+What:	/proc/<pid>/oom_adj
+When:	August 2012
+Why:	/proc/<pid>/oom_adj allows userspace to influence the oom killer's
+	badness heuristic used to determine which task to kill when the kernel
+	is out of memory.
+
+	The badness heuristic has since been rewritten since the introduction of
+	this tunable such that its meaning is deprecated.  The value was
+	implemented as a bitshift on a score generated by the badness()
+	function that did not have any precise units of measure.  With the
+	rewrite, the score is given as a proportion of available memory to the
+	task allocating pages, so using a bitshift which grows the score
+	exponentially is, thus, impossible to tune with fine granularity.
+
+	A much more powerful interface, /proc/<pid>/oom_score_adj, was
+	introduced with the oom killer rewrite that allows users to increase or
+	decrease the badness() score linearly.  This interface will replace
+	/proc/<pid>/oom_adj.
+
+	A warning will be emitted to the kernel log if an application uses this
+	deprecated interface.  After it is printed once, future warnings will be
+	suppressed until the kernel is rebooted.

+Description:
+
+Being used for adding and removing rbd block devices.
+
+Usage: <mon ip addr> <options> <pool name> <rbd image name> [snap name]
+
+ $ echo "192.168.0.1 name=admin rbd foo" > /sys/bus/rbd/add
+
+The snapshot name can be "-" or omitted to map the image read/write. A <dev-id>
+will be assigned for any registered block device. If snapshot is used, it will
+be mapped read-only.
+
+Removal of a device:
+
+  $ echo <dev-id> > /sys/bus/rbd/remove
+
+Entries under /sys/bus/rbd/devices/<dev-id>/
+--------------------------------------------
+
+client_id
+
+	The ceph unique client id that was assigned for this specific session.
+
+major
+
+	The block device major number.
+
+name
+
+	The name of the rbd image.
+
+pool
+
+	The pool where this rbd image resides. The pool-name pair is unique
+	per rados system.
+
+size
+
+	The size (in bytes) of the mapped block device.
+
+refresh
+
+	Writing to this file will reread the image header data and set
+	all relevant datastructures accordingly.
+
+current_snap
+
+	The current snapshot for which the device is mapped.
+
+create_snap
+
+	Create a snapshot:
+
+	 $ echo <snap-name> > /sys/bus/rbd/devices/<dev-id>/snap_create
+
+rollback_snap
+
+	Rolls back data to the specified snapshot. This goes over the entire
+	list of rados blocks and sends a rollback command to each.
+
+	 $ echo <snap-name> > /sys/bus/rbd/devices/<dev-id>/snap_rollback
+
+snap_*
+
+	A directory per each snapshot
+
+
+Entries under /sys/bus/rbd/devices/<dev-id>/snap_<snap-name>
+-------------------------------------------------------------
+
+id

+
+This is split into rcu_preempt, rcu_sched, and rcu_bh sections, with the
+rcu_preempt section appearing only in CONFIG_TINY_PREEMPT_RCU builds.
+The last three lines of the rcu_preempt section appear only in
+CONFIG_RCU_BOOST kernel builds.  The fields are as follows:
+
+o	"qlen" is the number of RCU callbacks currently waiting either
+	for an RCU grace period or waiting to be invoked.  This is the
+	only field present for rcu_sched and rcu_bh, due to the
+	short-circuiting of grace period in those two cases.
+
+o	"gp" is the number of grace periods that have completed.
+
+o	"g197/p197/c197" displays the grace-period state, with the
+	"g" number being the number of grace periods that have started
+	(mod 256), the "p" number being the number of grace periods
+	that the CPU has responded to (also mod 256), and the "c"
+	number being the number of grace periods that have completed
+	(once again mode 256).
+
+	Why have both "gp" and "g"?  Because the data flowing into
+	"gp" is only present in a CONFIG_RCU_TRACE kernel.
+
+o	"tasks" is a set of bits.  The first bit is "T" if there are
+	currently tasks that have recently blocked within an RCU
+	read-side critical section, the second bit is "N" if any of the
+	aforementioned tasks are blocking the current RCU grace period,
+	and the third bit is "E" if any of the aforementioned tasks are
+	blocking the current expedited grace period.  Each bit is "."
+	if the corresponding condition does not hold.
+
+o	"ttb" is a single bit.  It is "B" if any of the blocked tasks
+	need to be priority boosted and "." otherwise.
+
+o	"btg" indicates whether boosting has been carried out during
+	the current grace period, with "exp" indicating that boosting
+	is in progress for an expedited grace period, "no" indicating
+	that boosting has not yet started for a normal grace period,
+	"begun" indicating that boosting has bebug for a normal grace
+	period, and "done" indicating that boosting has completed for
+	a normal grace period.
+
+o	"ntb" is the total number of tasks subjected to RCU priority boosting
+	periods since boot.
+
+o	"neb" is the number of expedited grace periods that have had
+	to resort to RCU priority boosting since boot.
+
+o	"nnb" is the number of normal grace periods that have had
+	to resort to RCU priority boosting since boot.
+
+o	"j" is the low-order 12 bits of the jiffies counter in hexadecimal.
+
+o	"bt" is the low-order 12 bits of the value that the jiffies counter
+	will have at the next time that boosting is scheduled to begin.
+
+o	In the line beginning with "normal balk", the fields are as follows:
+
+	o	"nt" is the number of times that the system balked from
+		boosting because there were no blocked tasks to boost.
+		Note that the system will balk from boosting even if the
+		grace period is overdue when the currently running task
+		is looping within an RCU read-side critical section.
+		There is no point in boosting in this case, because
+		boosting a running task won't make it run any faster.
+
+	o	"gt" is the number of times that the system balked
+		from boosting because, although there were blocked tasks,
+		none of them were preventing the current grace period
+		from completing.
+
+	o	"bt" is the number of times that the system balked
+		from boosting because boosting was already in progress.
+
+	o	"b" is the number of times that the system balked from
+		boosting because boosting had already completed for
+		the grace period in question.
+
+	o	"ny" is the number of times that the system balked from
+		boosting because it was not yet time to start boosting
+		the grace period in question.
+
+	o	"nos" is the number of times that the system balked from
+		boosting for inexplicable ("not otherwise specified")
+		reasons.  This can actually happen due to races involving
+		increments of the jiffies counter.
+
+o	In the line beginning with "exp balk", the fields are as follows:
+
+	o	"bt" is the number of times that the system balked from
+		boosting because there were no blocked tasks to boost.
+
+	o	"nos" is the number of times that the system balked from

+Software emulation of deprecated SWP instruction (CONFIG_SWP_EMULATE)
+---------------------------------------------------------------------
+
+ARMv6 architecture deprecates use of the SWP/SWPB instructions, and recommeds
+moving to the load-locked/store-conditional instructions LDREX and STREX.
+
+ARMv7 multiprocessing extensions introduce the ability to disable these
+instructions, triggering an undefined instruction exception when executed.
+Trapped instructions are emulated using an LDREX/STREX or LDREXB/STREXB
+sequence. If a memory access fault (an abort) occurs, a segmentation fault is
+signalled to the triggering process.
+
+/proc/cpu/swp_emulation holds some statistics/information, including the PID of
+the last process to trigger the emulation to be invocated. For example:
+---
+Emulated SWP:		12
+Emulated SWPB:		0
+Aborted SWP{B}:		1
+Last process:		314
+---
+
+NOTE: when accessing uncached shared regions, LDREX/STREX rely on an external
+transaction monitoring block called a global monitor to maintain update
+atomicity. If your system does not implement a global monitor, this option can
+cause programs that perform SWP operations to uncached memory to deadlock, as
+the STREX operation will always fail.

-Device Interfaces
-
-Introduction
-~~~~~~~~~~~~
-
-Device interfaces are the logical interfaces of device classes that correlate
-directly to userspace interfaces, like device nodes. 
-   
-Each device class may have multiple interfaces through which you can 
-access the same device. An input device may support the mouse interface, 
-the 'evdev' interface, and the touchscreen interface. A SCSI disk would 
-support the disk interface, the SCSI generic interface, and possibly a raw 
-device interface. 
-
-Device interfaces are registered with the class they belong to. As devices
-are added to the class, they are added to each interface registered with
-the class. The interface is responsible for determining whether the device
-supports the interface or not. 
-
-
-Programming Interface
-~~~~~~~~~~~~~~~~~~~~~
-
-struct device_interface {
-	char			* name;
-	rwlock_t		lock;
-	u32			devnum;
-	struct device_class	* devclass;
-
-	struct list_head	node;
-	struct driver_dir_entry	dir;
-
-	int (*add_device)(struct device *);
-	int (*add_device)(struct intf_data *);
-};
-
-int interface_register(struct device_interface *);
-void interface_unregister(struct device_interface *);
-
-
-An interface must specify the device class it belongs to. It is added
-to that class's list of interfaces on registration.
-
-
-Interfaces can be added to a device class at any time. Whenever it is
-added, each device in the class is passed to the interface's
-add_device callback. When an interface is removed, each device is
-removed from the interface.
-
-
-Devices
-~~~~~~~
-Once a device is added to a device class, it is added to each
-interface that is registered with the device class. The class
-is expected to place a class-specific data structure in 
-struct device::class_data. The interface can use that (along with
-other fields of struct device) to determine whether or not the driver
-and/or device support that particular interface.
-
-
-Data
-~~~~
-
-struct intf_data {
-	struct list_head	node;
-	struct device_interface	* intf;
-	struct device 		* dev;
-	u32			intf_num;
-};
-
-int interface_add_data(struct interface_data *);
-
-The interface is responsible for allocating and initializing a struct 
-intf_data and calling interface_add_data() to add it to the device's list
-of interfaces it belongs to. This list will be iterated over when the device
-is removed from the class (instead of all possible interfaces for a class).
-This structure should probably be embedded in whatever per-device data 
-structure the interface is allocating anyway.
-   
-Devices are enumerated within the interface. This happens in interface_add_data()
-and the enumerated value is stored in the struct intf_data for that device. 
-
-sysfs
-~~~~~
-Each interface is given a directory in the directory of the device
-class it belongs to:
-
-Interfaces get a directory in the class's directory as well:
-
-   class/
-   `-- input
-       |-- devices
-       |-- drivers
-       |-- mouse
-       `-- evdev
-
-When a device is added to the interface, a symlink is created that points 
-to the device's directory in the physical hierarchy:
-
-   class/
-   `-- input
-       |-- devices
-       |   `-- 1 -> ../../../root/pci0/00:1f.0/usb_bus/00:1f.2-1:0/
-       |-- drivers
-       |   `-- usb:usb_mouse -> ../../../bus/drivers/usb_mouse/
-       |-- mouse
-       |   `-- 1 -> ../../../root/pci0/00:1f.0/usb_bus/00:1f.2-1:0/
-       `-- evdev
-           `-- 1 -> ../../../root/pci0/00:1f.0/usb_bus/00:1f.2-1:0/
-
-
-Future Plans
-~~~~~~~~~~~~
-A device interface is correlated directly with a userspace interface
-for a device, specifically a device node. For instance, a SCSI disk
-exposes at least two interfaces to userspace: the standard SCSI disk
-interface and the SCSI generic interface. It might also export a raw
-device interface. 
-
-Many interfaces have a major number associated with them and each
-device gets a minor number. Or, multiple interfaces might share one
-major number, and each will receive a range of minor numbers (like in
-the case of input devices).
-
-These major and minor numbers could be stored in the interface
-structure. Major and minor allocations could happen when the interface
-is registered with the class, or via a helper function.

-RCU-based dcache locking model
-==============================
-
-On many workloads, the most common operation on dcache is to look up a
-dentry, given a parent dentry and the name of the child. Typically,
-for every open(), stat() etc., the dentry corresponding to the
-pathname will be looked up by walking the tree starting with the first
-component of the pathname and using that dentry along with the next
-component to look up the next level and so on. Since it is a frequent
-operation for workloads like multiuser environments and web servers,
-it is important to optimize this path.
-
-Prior to 2.5.10, dcache_lock was acquired in d_lookup and thus in
-every component during path look-up. Since 2.5.10 onwards, fast-walk
-algorithm changed this by holding the dcache_lock at the beginning and
-walking as many cached path component dentries as possible. This
-significantly decreases the number of acquisition of
-dcache_lock. However it also increases the lock hold time
-significantly and affects performance in large SMP machines. Since
-2.5.62 kernel, dcache has been using a new locking model that uses RCU
-to make dcache look-up lock-free.
-
-The current dcache locking model is not very different from the
-existing dcache locking model. Prior to 2.5.62 kernel, dcache_lock
-protected the hash chain, d_child, d_alias, d_lru lists as well as
-d_inode and several other things like mount look-up. RCU-based changes
-affect only the way the hash chain is protected. For everything else
-the dcache_lock must be taken for both traversing as well as
-updating. The hash chain updates too take the dcache_lock.  The
-significant change is the way d_lookup traverses the hash chain, it
-doesn't acquire the dcache_lock for this and rely on RCU to ensure
-that the dentry has not been *freed*.
-
-
-Dcache locking details
-======================
-
-For many multi-user workloads, open() and stat() on files are very
-frequently occurring operations. Both involve walking of path names to
-find the dentry corresponding to the concerned file. In 2.4 kernel,
-dcache_lock was held during look-up of each path component. Contention
-and cache-line bouncing of this global lock caused significant
-scalability problems. With the introduction of RCU in Linux kernel,
-this was worked around by making the look-up of path components during
-path walking lock-free.
-
-
-Safe lock-free look-up of dcache hash table
-===========================================
-
-Dcache is a complex data structure with the hash table entries also
-linked together in other lists. In 2.4 kernel, dcache_lock protected
-all the lists. We applied RCU only on hash chain walking. The rest of
-the lists are still protected by dcache_lock.  Some of the important
-changes are :
-
-1. The deletion from hash chain is done using hlist_del_rcu() macro
-   which doesn't initialize next pointer of the deleted dentry and
-   this allows us to walk safely lock-free while a deletion is
-   happening.
-
-2. Insertion of a dentry into the hash table is done using
-   hlist_add_head_rcu() which take care of ordering the writes - the
-   writes to the dentry must be visible before the dentry is
-   inserted. This works in conjunction with hlist_for_each_rcu(),
-   which has since been replaced by hlist_for_each_entry_rcu(), while
-   walking the hash chain. The only requirement is that all
-   initialization to the dentry must be done before
-   hlist_add_head_rcu() since we don't have dcache_lock protection
-   while traversing the hash chain. This isn't different from the
-   existing code.
-
-3. The dentry looked up without holding dcache_lock by cannot be
-   returned for walking if it is unhashed. It then may have a NULL
-   d_inode or other bogosity since RCU doesn't protect the other
-   fields in the dentry. We therefore use a flag DCACHE_UNHASHED to
-   indicate unhashed dentries and use this in conjunction with a
-   per-dentry lock (d_lock). Once looked up without the dcache_lock,
-   we acquire the per-dentry lock (d_lock) and check if the dentry is
-   unhashed. If so, the look-up is failed. If not, the reference count
-   of the dentry is increased and the dentry is returned.
-
-4. Once a dentry is looked up, it must be ensured during the path walk
-   for that component it doesn't go away. In pre-2.5.10 code, this was
-   done holding a reference to the dentry. dcache_rcu does the same.
-   In some sense, dcache_rcu path walking looks like the pre-2.5.10
-   version.
-
-5. All dentry hash chain updates must take the dcache_lock as well as
-   the per-dentry lock in that order. dput() does this to ensure that
-   a dentry that has just been looked up in another CPU doesn't get
-   deleted before dget() can be done on it.
-
-6. There are several ways to do reference counting of RCU protected
-   objects. One such example is in ipv4 route cache where deferred
-   freeing (using call_rcu()) is done as soon as the reference count
-   goes to zero. This cannot be done in the case of dentries because
-   tearing down of dentries require blocking (dentry_iput()) which
-   isn't supported from RCU callbacks. Instead, tearing down of
-   dentries happen synchronously in dput(), but actual freeing happens
-   later when RCU grace period is over. This allows safe lock-free
-   walking of the hash chains, but a matched dentry may have been
-   partially torn down. The checking of DCACHE_UNHASHED flag with
-   d_lock held detects such dentries and prevents them from being
-   returned from look-up.
-
-
-Maintaining POSIX rename semantics
-==================================
-
-Since look-up of dentries is lock-free, it can race against a
-concurrent rename operation. For example, during rename of file A to
-B, look-up of either A or B must succeed.  So, if look-up of B happens
-after A has been removed from the hash chain but not added to the new
-hash chain, it may fail.  Also, a comparison while the name is being
-written concurrently by a rename may result in false positive matches
-violating rename semantics.  Issues related to race with rename are
-handled as described below :
-
-1. Look-up can be done in two ways - d_lookup() which is safe from
-   simultaneous renames and __d_lookup() which is not.  If
-   __d_lookup() fails, it must be followed up by a d_lookup() to
-   correctly determine whether a dentry is in the hash table or
-   not. d_lookup() protects look-ups using a sequence lock
-   (rename_lock).
-
-2. The name associated with a dentry (d_name) may be changed if a
-   rename is allowed to happen simultaneously. To avoid memcmp() in
-   __d_lookup() go out of bounds due to a rename and false positive
-   comparison, the name comparison is done while holding the
-   per-dentry lock. This prevents concurrent renames during this
-   operation.
-
-3. Hash table walking during look-up may move to a different bucket as
-   the current dentry is moved to a different bucket due to rename.
-   But we use hlists in dcache hash table and they are
-   null-terminated.  So, even if a dentry moves to a different bucket,
-   hash chain walk will terminate. [with a list_head list, it may not
-   since termination is when the list_head in the original bucket is
-   reached].  Since we redo the d_parent check and compare name while
-   holding d_lock, lock-free look-up will not race against d_move().
-
-4. There can be a theoretical race when a dentry keeps coming back to
-   original bucket due to double moves. Due to this look-up may
-   consider that it has never moved and can end up in a infinite loop.
-   But this is not any worse that theoretical livelocks we already
-   have in the kernel.
-
-
-Important guidelines for filesystem developers related to dcache_rcu
-====================================================================
-
-1. Existing dcache interfaces (pre-2.5.62) exported to filesystem
-   don't change. Only dcache internal implementation changes. However
-   filesystems *must not* delete from the dentry hash chains directly
-   using the list macros like allowed earlier. They must use dcache
-   APIs like d_drop() or __d_drop() depending on the situation.
-
-2. d_flags is now protected by a per-dentry lock (d_lock). All access
-   to d_flags must be protected by it.
-
-3. For a hashed dentry, checking of d_count needs to be protected by
-   d_lock.

+Path walking and name lookup locking
+====================================
+
+Path resolution is the finding a dentry corresponding to a path name string, by
+performing a path walk. Typically, for every open(), stat() etc., the path name
+will be resolved. Paths are resolved by walking the namespace tree, starting
+with the first component of the pathname (eg. root or cwd) with a known dentry,
+then finding the child of that dentry, which is named the next component in the
+path string. Then repeating the lookup from the child dentry and finding its
+child with the next element, and so on.
+
+Since it is a frequent operation for workloads like multiuser environments and
+web servers, it is important to optimize this code.
+
+Path walking synchronisation history:
+Prior to 2.5.10, dcache_lock was acquired in d_lookup (dcache hash lookup) and
+thus in every component during path look-up. Since 2.5.10 onwards, fast-walk
+algorithm changed this by holding the dcache_lock at the beginning and walking
+as many cached path component dentries as possible. This significantly
+decreases the number of acquisition of dcache_lock. However it also increases
+the lock hold time significantly and affects performance in large SMP machines.
+Since 2.5.62 kernel, dcache has been using a new locking model that uses RCU to
+make dcache look-up lock-free.
+
+All the above algorithms required taking a lock and reference count on the
+dentry that was looked up, so that may be used as the basis for walking the
+next path element. This is inefficient and unscalable. It is inefficient
+because of the locks and atomic operations required for every dentry element
+slows things down. It is not scalable because many parallel applications that
+are path-walk intensive tend to do path lookups starting from a common dentry
+(usually, the root "/" or current working directory). So contention on these
+common path elements causes lock and cacheline queueing.
+
+Since 2.6.38, RCU is used to make a significant part of the entire path walk
+(including dcache look-up) completely "store-free" (so, no locks, atomics, or
+even stores into cachelines of common dentries). This is known as "rcu-walk"
+path walking.
+
+Path walking overview
+=====================
+
+A name string specifies a start (root directory, cwd, fd-relative) and a
+sequence of elements (directory entry names), which together refer to a path in
+the namespace. A path is represented as a (dentry, vfsmount) tuple. The name
+elements are sub-strings, seperated by '/'.
+
+Name lookups will want to find a particular path that a name string refers to
+(usually the final element, or parent of final element). This is done by taking
+the path given by the name's starting point (which we know in advance -- eg.
+current->fs->cwd or current->fs->root) as the first parent of the lookup. Then
+iteratively for each subsequent name element, look up the child of the current
+parent with the given name and if it is not the desired entry, make it the
+parent for the next lookup.
+
+A parent, of course, must be a directory, and we must have appropriate
+permissions on the parent inode to be able to walk into it.
+
+Turning the child into a parent for the next lookup requires more checks and
+procedures. Symlinks essentially substitute the symlink name for the target
+name in the name string, and require some recursive path walking.  Mount points
+must be followed into (thus changing the vfsmount that subsequent path elements
+refer to), switching from the mount point path to the root of the particular
+mounted vfsmount. These behaviours are variously modified depending on the
+exact path walking flags.
+
+Path walking then must, broadly, do several particular things:
+- find the start point of the walk;
+- perform permissions and validity checks on inodes;
+- perform dcache hash name lookups on (parent, name element) tuples;
+- traverse mount points;
+- traverse symlinks;
+- lookup and create missing parts of the path on demand.
+
+Safe store-free look-up of dcache hash table
+============================================
+
+Dcache name lookup
+------------------
+In order to lookup a dcache (parent, name) tuple, we take a hash on the tuple
+and use that to select a bucket in the dcache-hash table. The list of entries
+in that bucket is then walked, and we do a full comparison of each entry
+against our (parent, name) tuple.
+
+The hash lists are RCU protected, so list walking is not serialised with
+concurrent updates (insertion, deletion from the hash). This is a standard RCU
+list application with the exception of renames, which will be covered below.
+
+Parent and name members of a dentry, as well as its membership in the dcache
+hash, and its inode are protected by the per-dentry d_lock spinlock. A
+reference is taken on the dentry (while the fields are verified under d_lock),
+and this stabilises its d_inode pointer and actual inode. This gives a stable
+point to perform the next step of our path walk against.
+
+These members are also protected by d_seq seqlock, although this offers
+read-only protection and no durability of results, so care must be taken when
+using d_seq for synchronisation (see seqcount based lookups, below).
+
+Renames
+-------
+Back to the rename case. In usual RCU protected lists, the only operations that
+will happen to an object is insertion, and then eventually removal from the
+list. The object will not be reused until an RCU grace period is complete.
+This ensures the RCU list traversal primitives can run over the object without
+problems (see RCU documentation for how this works).
+
+However when a dentry is renamed, its hash value can change, requiring it to be
+moved to a new hash list. Allocating and inserting a new alias would be
+expensive and also problematic for directory dentries. Latency would be far to
+high to wait for a grace period after removing the dentry and before inserting
+it in the new hash bucket. So what is done is to insert the dentry into the
+new list immediately.
+
+However, when the dentry's list pointers are updated to point to objects in the
+new list before waiting for a grace period, this can result in a concurrent RCU
+lookup of the old list veering off into the new (incorrect) list and missing
+the remaining dentries on the list.
+
+There is no fundamental problem with walking down the wrong list, because the
+dentry comparisons will never match. However it is fatal to miss a matching
+dentry. So a seqlock is used to detect when a rename has occurred, and so the
+lookup can be retried.

+
+This is a standard RCU-list deletion, which leaves the deleted object's
+pointers intact, so a concurrent list walker that is currently looking at
+object 2 will correctly continue to object 3 when it is time to traverse the
+next object.
+
+However, when inserting object 2 onto a new list, we end up with this:
+
+         1             3
+        +---+         +---+

+          <----+-P |
+               +---+
+
+Because we didn't wait for a grace period, there may be a concurrent lookup
+still at 2. Now when it follows 2's 'next' pointer, it will walk off into
+another list without ever having checked object 3.
+
+A related, but distinctly different, issue is that of rename atomicity versus
+lookup operations. If a file is renamed from 'A' to 'B', a lookup must only
+find either 'A' or 'B'. So if a lookup of 'A' returns NULL, a subsequent lookup
+of 'B' must succeed (note the reverse is not true).
+
+Between deleting the dentry from the old hash list, and inserting it on the new
+hash list, a lookup may find neither 'A' nor 'B' matching the dentry. The same
+rename seqlock is also used to cover this race in much the same way, by
+retrying a negative lookup result if a rename was in progress.
+
+Seqcount based lookups
+----------------------
+In refcount based dcache lookups, d_lock is used to serialise access to
+the dentry, stabilising it while comparing its name and parent and then
+taking a reference count (the reference count then gives a stable place to
+start the next part of the path walk from).
+
+As explained above, we would like to do path walking without taking locks or
+reference counts on intermediate dentries along the path. To do this, a per
+dentry seqlock (d_seq) is used to take a "coherent snapshot" of what the dentry
+looks like (its name, parent, and inode). That snapshot is then used to start
+the next part of the path walk. When loading the coherent snapshot under d_seq,
+care must be taken to load the members up-front, and use those pointers rather
+than reloading from the dentry later on (otherwise we'd have interesting things
+like d_inode going NULL underneath us, if the name was unlinked).
+
+Also important is to avoid performing any destructive operations (pretty much:
+no non-atomic stores to shared data), and to recheck the seqcount when we are
+"done" with the operation. Retry or abort if the seqcount does not match.
+Avoiding destructive or changing operations means we can easily unwind from
+failure.
+
+What this means is that a caller, provided they are holding RCU lock to
+protect the dentry object from disappearing, can perform a seqcount based
+lookup which does not increment the refcount on the dentry or write to
+it in any way. This returned dentry can be used for subsequent operations,
+provided that d_seq is rechecked after that operation is complete.
+
+Inodes are also rcu freed, so the seqcount lookup dentry's inode may also be
+queried for permissions.
+
+With this two parts of the puzzle, we can do path lookups without taking
+locks or refcounts on dentry elements.
+
+RCU-walk path walking design
+============================
+
+Path walking code now has two distinct modes, ref-walk and rcu-walk. ref-walk
+is the traditional[*] way of performing dcache lookups using d_lock to
+serialise concurrent modifications to the dentry and take a reference count on
+it. ref-walk is simple and obvious, and may sleep, take locks, etc while path
+walking is operating on each dentry. rcu-walk uses seqcount based dentry
+lookups, and can perform lookup of intermediate elements without any stores to
+shared data in the dentry or inode. rcu-walk can not be applied to all cases,
+eg. if the filesystem must sleep or perform non trivial operations, rcu-walk
+must be switched to ref-walk mode.
+
+[*] RCU is still used for the dentry hash lookup in ref-walk, but not the full
+    path walk.
+
+Where ref-walk uses a stable, refcounted ``parent'' to walk the remaining
+path string, rcu-walk uses a d_seq protected snapshot. When looking up a
+child of this parent snapshot, we open d_seq critical section on the child
+before closing d_seq critical section on the parent. This gives an interlocking
+ladder of snapshots to walk down.
+
+
+     proc 101
+      /----------------\
+     / comm:    "vi"    \
+    /  fs.root: dentry0  \
+    \  fs.cwd:  dentry2  /
+     \                  /
+      \----------------/
+
+So when vi wants to open("/home/npiggin/test.c", O_RDWR), then it will
+start from current->fs->root, which is a pinned dentry. Alternatively,
+"./test.c" would start from cwd; both names refer to the same path in
+the context of proc101.
+
+     dentry 0
+    +---------------------+   rcu-walk begins here, we note d_seq, check the
+    | name:    "/"        |   inode's permission, and then look up the next
+    | inode:   10         |   path element which is "home"...
+    | children:"home", ...|
+    +---------------------+
+              |
+     dentry 1 V
+    +---------------------+   ... which brings us here. We find dentry1 via
+    | name:    "home"     |   hash lookup, then note d_seq and compare name
+    | inode:   678        |   string and parent pointer. When we have a match,
+    | children:"npiggin"  |   we now recheck the d_seq of dentry0. Then we
+    +---------------------+   check inode and look up the next element.
+              |
+     dentry2  V
+    +---------------------+   Note: if dentry0 is now modified, lookup is
+    | name:    "npiggin"  |   not necessarily invalid, so we need only keep a
+    | inode:   543        |   parent for d_seq verification, and grandparents
+    | children:"a.c", ... |   can be forgotten.
+    +---------------------+
+              |
+     dentry3  V
+    +---------------------+   At this point we have our destination dentry.
+    | name:    "a.c"      |   We now take its d_lock, verify d_seq of this
+    | inode:   14221      |   dentry. If that checks out, we can increment
+    | children:NULL       |   its refcount because we're holding d_lock.
+    +---------------------+
+
+Taking a refcount on a dentry from rcu-walk mode, by taking its d_lock,
+re-checking its d_seq, and then incrementing its refcount is called
+"dropping rcu" or dropping from rcu-walk into ref-walk mode.
+
+It is, in some sense, a bit of a house of cards. If the seqcount check of the
+parent snapshot fails, the house comes down, because we had closed the d_seq
+section on the grandparent, so we have nothing left to stand on. In that case,
+the path walk must be fully restarted (which we do in ref-walk mode, to avoid
+live locks). It is costly to have a full restart, but fortunately they are
+quite rare.
+
+When we reach a point where sleeping is required, or a filesystem callout
+requires ref-walk, then instead of restarting the walk, we attempt to drop rcu
+at the last known good dentry we have. Avoiding a full restart in ref-walk in
+these cases is fundamental for performance and scalability because blocking
+operations such as creates and unlinks are not uncommon.
+
+The detailed design for rcu-walk is like this:
+* LOOKUP_RCU is set in nd->flags, which distinguishes rcu-walk from ref-walk.
+* Take the RCU lock for the entire path walk, starting with the acquiring
+  of the starting path (eg. root/cwd/fd-path). So now dentry refcounts are
+  not required for dentry persistence.
+* synchronize_rcu is called when unregistering a filesystem, so we can
+  access d_ops and i_ops during rcu-walk.
+* Similarly take the vfsmount lock for the entire path walk. So now mnt
+  refcounts are not required for persistence. Also we are free to perform mount
+  lookups, and to assume dentry mount points and mount roots are stable up and
+  down the path.
+* Have a per-dentry seqlock to protect the dentry name, parent, and inode,
+  so we can load this tuple atomically, and also check whether any of its
+  members have changed.
+* Dentry lookups (based on parent, candidate string tuple) recheck the parent
+  sequence after the child is found in case anything changed in the parent
+  during the path walk.
+* inode is also RCU protected so we can load d_inode and use the inode for
+  limited things.
+* i_mode, i_uid, i_gid can be tested for exec permissions during path walk.
+* i_op can be loaded.
+* When the destination dentry is reached, drop rcu there (ie. take d_lock,
+  verify d_seq, increment refcount).
+* If seqlock verification fails anywhere along the path, do a full restart
+  of the path lookup in ref-walk mode. -ECHILD tends to be used (for want of
+  a better errno) to signal an rcu-walk failure.
+
+The cases where rcu-walk cannot continue are:
+* NULL dentry (ie. any uncached path element)
+* Following links
+
+It may be possible eventually to make following links rcu-walk aware.
+
+Uncached path elements will always require dropping to ref-walk mode, at the
+very least because i_mutex needs to be grabbed, and objects allocated.
+
+Final note:
+"store-free" path walking is not strictly store free. We take vfsmount lock
+and refcounts (both of which can be made per-cpu), and we also store to the
+stack (which is essentially CPU-local), and we also have to take locks and
+refcount on final dentry.
+
+The point is that shared data, where practically possible, is not locked
+or stored into. The result is massive improvements in performance and
+scalability of path resolution.
+
+
+Interesting statistics
+======================
+
+The following table gives rcu lookup statistics for a few simple workloads
+(2s12c24t Westmere, debian non-graphical system). Ungraceful are attempts to
+drop rcu that fail due to d_seq failure and requiring the entire path lookup
+again. Other cases are successful rcu-drops that are required before the final
+element, nodentry for missing dentry, revalidate for filesystem revalidate
+routine requiring rcu drop, permission for permission check requiring drop,
+and link for symlink traversal requiring drop.
+
+     rcu-lookups     restart  nodentry          link  revalidate  permission
+bootup     47121           0      4624          1010       10283        7852
+dbench  25386793           0   6778659(26.7%)     55         549        1156
+kbuild   2696672          10     64442(2.3%)  108764(4.0%)     1        1590
+git diff   39605           0        28             2           0         106
+vfstest 24185492        4945    708725(2.9%) 1076136(4.4%)     0        2651
+
+What this shows is that failed rcu-walk lookups, ie. ones that are restarted
+entirely with ref-walk, are quite rare. Even the "vfstest" case which
+specifically has concurrent renames/mkdir/rmdir/ creat/unlink/etc to excercise
+such races is not showing a huge amount of restarts.
+
+Dropping from rcu-walk to ref-walk mean that we have encountered a dentry where
+the reference count needs to be taken for some reason. This is either because
+we have reached the target of the path walk, or because we have encountered a
+condition that can't be resolved in rcu-walk mode.  Ideally, we drop rcu-walk
+only when we have reached the target dentry, so the other statistics show where
+this does not happen.
+
+Note that a graceful drop from rcu-walk mode due to something such as the
+dentry not existing (which can be common) is not necessarily a failure of
+rcu-walk scheme, because some elements of the path may have been walked in
+rcu-walk mode. The further we get from common path elements (such as cwd or
+root), the less contended the dentry is likely to be. The closer we are to
+common path elements, the more likely they will exist in dentry cache.

+Description
+-----------
+CMA3000 Tri-axis accelerometer supports Motion detect, Measurement and
+Free fall modes.
+
+Motion Detect Mode: Its the low power mode where interrupts are generated only
+when motion exceeds the defined thresholds.
+
+Measurement Mode: This mode is used to read the acceleration data on X,Y,Z
+axis and supports 400, 100, 40 Hz sample frequency.
+
+Free fall Mode: This mode is intended to save system resources.
+
+Threshold values: Chip supports defining threshold values for above modes
+which includes time and g value. Refer product specifications for more details.
+
+CMA3000 chip supports mutually exclusive I2C and SPI interfaces for
+communication, currently the driver supports I2C based communication only.
+Initial configuration for bus mode is set in non volatile memory and can later
+be modified through bus interface command.
+
+Driver reports acceleration data through input subsystem. It generates ABS_MISC
+event with value 1 when free fall is detected.
+
+Platform data need to be configured for initial default values.

+timers that may have been required for blinking.
+
+The blink_set() function should choose a user friendly blinking value
+if it is called with *delay_on==0 && *delay_off==0 parameters. In this
+case the driver should give back the chosen value through delay_on and
+delay_off parameters to the leds subsystem.
 
 Setting the brightness to zero with brightness_set() callback function
 should completely turn off the LED and cancel the previously programmed

+Description
+-----------
+
+LP5521 can drive up to 3 channels. Leds can be controlled directly via
+the led class control interface. Channels have generic names:
+lp5521:channelx, where x is 0 .. 2
+
+All three channels can be also controlled using the engine micro programs.
+More details of the instructions can be found from the public data sheet.
+
+Control interface for the engines:
+x is 1 .. 3
+enginex_mode : disabled, load, run
+enginex_load : store program (visible only in engine load mode)
+
+Example (start to blink the channel 2 led):
+cd   /sys/class/leds/lp5521:channel2/device
+echo "load" > engine3_mode
+echo "037f4d0003ff6000" > engine3_load
+echo "run" > engine3_mode
+
+stop the engine:
+echo "disabled" > engine3_mode
+
+sysfs contains a selftest entry.
+The test communicates with the chip and checks that
+the clock mode is automatically set to the requested one.
+
+Each channel has its own led current settings.

+Kernel driver for lp5523
+========================

+Description
+-----------
+LP5523 can drive up to 9 channels. Leds can be controlled directly via
+the led class control interface. Channels have generic names:
+lp5523:channelx where x is 0...8
+
+The chip provides 3 engines. Each engine can control channels without
+interaction from the main CPU. Details of the micro engine code can be found
+from the public data sheet. Leds can be muxed to different channels.
+
+Control interface for the engines:
+x is 1 .. 3
+enginex_mode : disabled, load, run
+enginex_load : microcode load (visible only in load mode)
+enginex_leds : led mux control (visible only in load mode)
+
+cd /sys/class/leds/lp5523:channel2/device
+echo "load" > engine3_mode
+echo "9d80400004ff05ff437f0000" > engine3_load
+echo "111111111" > engine3_leds
+echo "run" > engine3_mode
+
+sysfs contains a selftest entry. It measures each channel
+voltage level and checks if it looks reasonable. If the level is too high,
+the led is missing; if the level is too low, there is a short circuit.
+
+Selftest uses always the current from the platform data.
+
+Each channel contains led current settings.

+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                           Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                   GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                           NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.

+
+BATMAN-ADV
+----------
+
+Batman  advanced  is  a new approach to wireless networking which
+does no longer operate on the IP basis. Unlike the batman daemon,
+which  exchanges  information  using UDP packets and sets routing
+tables, batman-advanced operates on ISO/OSI Layer 2 only and uses
+and  routes  (or  better: bridges) Ethernet Frames. It emulates a
+virtual network switch of all nodes participating.  Therefore all
+nodes  appear  to be link local, thus all higher operating proto-
+cols won't be affected by any changes within the network. You can
+run almost any protocol above batman advanced, prominent examples
+are: IPv4, IPv6, DHCP, IPX.
+
+Batman advanced was implemented as a Linux kernel driver  to  re-
+duce the overhead to a minimum. It does not depend on any (other)
+network driver, and can be used on wifi as well as ethernet  lan,
+vpn,  etc ... (anything with ethernet-style layer 2).
+
+CONFIGURATION
+-------------
+
+Load the batman-adv module into your kernel:
+
+# insmod batman-adv.ko
+
+The  module  is now waiting for activation. You must add some in-
+terfaces on which batman can operate. After  loading  the  module
+batman  advanced  will scan your systems interfaces to search for
+compatible interfaces. Once found, it will create  subfolders  in
+the /sys directories of each supported interface, e.g.
+
+# ls /sys/class/net/eth0/batman_adv/
+# iface_status  mesh_iface
+
+If an interface does not have the "batman_adv" subfolder it prob-
+ably is not supported. Not supported  interfaces  are:  loopback,
+non-ethernet and batman's own interfaces.
+
+Note:  After the module was loaded it will continuously watch for
+new interfaces to verify the compatibility. There is no  need  to
+reload the module if you plug your USB wifi adapter into your ma-
+chine after batman advanced was initially loaded.
+
+To activate a  given  interface  simply  write  "bat0"  into  its
+"mesh_iface" file inside the batman_adv subfolder:
+
+# echo bat0 > /sys/class/net/eth0/batman_adv/mesh_iface
+
+Repeat  this step for all interfaces you wish to add.  Now batman
+starts using/broadcasting on this/these interface(s).
+
+By reading the "iface_status" file you can check its status:
+
+# cat /sys/class/net/eth0/batman_adv/iface_status
+# active
+
+To deactivate an interface you have  to  write  "none"  into  its
+"mesh_iface" file:
+
+# echo none > /sys/class/net/eth0/batman_adv/mesh_iface
+
+
+All  mesh  wide  settings  can be found in batman's own interface
+folder:
+
+#  ls  /sys/class/net/bat0/mesh/
+#  aggregated_ogms  bonding  fragmentation  orig_interval
+#  vis_mode
+
+
+There is a special folder for debugging informations:
+
+#  ls /sys/kernel/debug/batman_adv/bat0/
+#  originators  socket  transtable_global  transtable_local
+#  vis_data
+
+
+Some of the files contain all sort of status information  regard-
+ing  the  mesh  network.  For  example, you can view the table of
+originators (mesh participants) with:
+
+# cat /sys/kernel/debug/batman_adv/bat0/originators
+
+Other files allow to change batman's behaviour to better fit your
+requirements.  For instance, you can check the current originator
+interval (value in milliseconds which determines how often batman
+sends its broadcast packets):
+
+# cat /sys/class/net/bat0/mesh/orig_interval
+# 1000
+
+and also change its value:
+
+# echo 3000 > /sys/class/net/bat0/mesh/orig_interval
+
+In very mobile scenarios, you might want to adjust the originator
+interval to a lower value. This will make the mesh  more  respon-
+sive to topology changes, but will also increase the overhead.
+
+
+USAGE
+-----
+
+To  make use of your newly created mesh, batman advanced provides
+a new interface "bat0" which you should use from this  point  on.
+All  interfaces  added  to  batman  advanced are not relevant any
+longer because batman handles them for you. Basically, one "hands
+over" the data by using the batman interface and batman will make
+sure it reaches its destination.
+
+The "bat0" interface can be used like any  other  regular  inter-
+face.  It needs an IP address which can be either statically con-
+figured or dynamically (by using DHCP or similar services):
+
+# NodeA: ifconfig bat0 192.168.0.1
+# NodeB: ifconfig bat0 192.168.0.2
+# NodeB: ping 192.168.0.1
+
+Note:  In  order to avoid problems remove all IP addresses previ-
+ously assigned to interfaces now used by batman advanced, e.g.
+
+# ifconfig eth0 0.0.0.0
+
+
+VISUALIZATION
+-------------
+
+If you want topology visualization, at least one mesh  node  must
+be configured as VIS-server:
+
+# echo "server" > /sys/class/net/bat0/mesh/vis_mode
+
+Each  node  is  either configured as "server" or as "client" (de-
+fault: "client").  Clients send their topology data to the server
+next to them, and server synchronize with other servers. If there
+is no server configured (default) within the  mesh,  no  topology
+information   will  be  transmitted.  With  these  "synchronizing
+servers", there can be 1 or more vis servers sharing the same (or
+at least very similar) data.
+
+When  configured  as  server,  you can get a topology snapshot of
+your mesh:
+
+# cat /sys/kernel/debug/batman_adv/bat0/vis_data
+
+This raw output is intended to be easily parsable and convertable
+with  other tools. Have a look at the batctl README if you want a
+vis output in dot or json format for instance and how those  out-
+puts could then be visualised in an image.
+
+The raw format consists of comma separated values per entry where
+each entry is giving information about a  certain  source  inter-
+face.  Each  entry can/has to have the following values:
+-> "mac" - mac address of an originator's source interface
+           (each line begins with it)
+-> "TQ mac  value"  -  src mac's link quality towards mac address
+                       of a neighbor originator's interface which
+                       is being used for routing
+-> "HNA mac" - HNA announced by source mac
+-> "PRIMARY" - this  is a primary interface
+-> "SEC mac" - secondary mac address of source
+               (requires preceding PRIMARY)
+
+The TQ value has a range from 4 to 255 with 255 being  the  best.
+The HNA entries are showing which hosts are connected to the mesh
+via bat0 or being bridged into the mesh network.  The PRIMARY/SEC
+values are only applied on primary interfaces
+
+
+LOGGING/DEBUGGING
+-----------------
+
+All error messages, warnings and information messages are sent to
+the kernel log. Depending on your operating  system  distribution
+this  can  be read in one of a number of ways. Try using the com-
+mands: dmesg, logread, or looking in the files  /var/log/kern.log
+or  /var/log/syslog.  All  batman-adv  messages are prefixed with
+"batman-adv:" So to see just these messages try
+
+# dmesg | grep batman-adv
+
+When investigating problems with your mesh network  it  is  some-
+times  necessary  to see more detail debug messages. This must be
+enabled when compiling the batman-adv module. When building  bat-
+man-adv  as  part of kernel, use "make menuconfig" and enable the
+option "B.A.T.M.A.N. debugging".
+
+Those additional  debug messages can be accessed  using a special
+file in debugfs
+
+# cat /sys/kernel/debug/batman_adv/bat0/log
+
+The additional debug output is by default disabled. It can be en-
+abled  during run time. Following log_levels are defined:
+
+0 - All  debug  output  disabled
+1 - Enable messages related to routing / flooding / broadcasting
+2 - Enable route or hna added / changed / deleted
+3 - Enable all messages
+
+The debug output can be changed at runtime  using  the  file
+/sys/class/net/bat0/mesh/log_level. e.g.
+
+# echo 2 > /sys/class/net/bat0/mesh/log_level
+
+will enable debug messages for when routes or HNAs change.
+
+
+BATCTL
+------
+
+As batman advanced operates on layer 2 all hosts participating in
+the  virtual switch are completely transparent for all  protocols
+above layer 2. Therefore the common diagnosis tools do  not  work
+as  expected.  To  overcome these problems batctl was created. At
+the  moment the  batctl contains ping,  traceroute,  tcpdump  and
+interfaces to the kernel module settings.
+
+For more information, please see the manpage (man batctl).
+
+batctl is available on http://www.open-mesh.org/

 Socket options
 ==============
+DCCP_SOCKOPT_QPOLICY_ID sets the dequeuing policy for outgoing packets. It takes
+a policy ID as argument and can only be set before the connection (i.e. changes
+during an established connection are not supported). Currently, two policies are
+defined: the "simple" policy (DCCPQ_POLICY_SIMPLE), which does nothing special,
+and a priority-based variant (DCCPQ_POLICY_PRIO). The latter allows to pass an
+u32 priority value as ancillary data to sendmsg(), where higher numbers indicate
+a higher packet priority (similar to SO_PRIORITY). This ancillary data needs to
+be formatted using a cmsg(3) message header filled in as follows:
+	cmsg->cmsg_level = SOL_DCCP;
+	cmsg->cmsg_type	 = DCCP_SCM_PRIORITY;
+	cmsg->cmsg_len	 = CMSG_LEN(sizeof(uint32_t));	/* or CMSG_LEN(4) */
+
+DCCP_SOCKOPT_QPOLICY_TXQLEN sets the maximum length of the output queue. A zero
+value is always interpreted as unbounded queue length. If different from zero,
+the interpretation of this parameter depends on the current dequeuing policy
+(see above): the "simple" policy will enforce a fixed queue size by returning
+EAGAIN, whereas the "prio" policy enforces a fixed queue length by dropping the
+lowest-priority packet first. The default value for this parameter is
+initialised from /proc/sys/net/dccp/default/tx_qlen.
+
 DCCP_SOCKOPT_SERVICE sets the service. The specification mandates use of
 service codes (RFC 4340, sec. 8.1.2); if this socket option is not set,
 the socket will fall back to 0 (which means that no meaningful service code

-3. Assign an IP address to the interface by entering the following, where
-   x is the interface number:
 
-     ifconfig ethx <IP_address>
+Flow Control
+------------
+Ethernet Flow Control (IEEE 802.3x) can be configured with ethtool to enable
+receiving and transmitting pause frames for ixgbe. When TX is enabled, PAUSE
+frames are generated when the receive packet buffer crosses a predefined
+threshold.  When rx is enabled, the transmit unit will halt for the time delay
+specified when a PAUSE frame is received.
 
-4. Verify that the interface works. Enter the following, where <IP_address>
-   is the IP address for another machine on the same subnet as the interface
-   that is being tested:
+Flow Control is enabled by default. If you want to disable a flow control
+capable link partner, use ethtool:
 
-     ping  <IP_address>
+     ethtool -A eth? autoneg off RX off TX off
 
+NOTE: For 82598 backplane cards entering 1 gig mode, flow control default
+behavior is changed to off.  Flow control in 1 gig mode on these devices can
+lead to Tx hangs.

+  Enabling SR-IOV in a 32-bit Microsoft* Windows* Server 2008 Guest OS using
+  Intel (R) 82576-based GbE or Intel (R) 82599-based 10GbE controller under KVM
+  -----------------------------------------------------------------------------
+  KVM Hypervisor/VMM supports direct assignment of a PCIe device to a VM.  This
+  includes traditional PCIe devices, as well as SR-IOV-capable devices using
+  Intel 82576-based and 82599-based controllers.
+
+  While direct assignment of a PCIe device or an SR-IOV Virtual Function (VF)
+  to a Linux-based VM running 2.6.32 or later kernel works fine, there is a
+  known issue with Microsoft Windows Server 2008 VM that results in a "yellow
+  bang" error. This problem is within the KVM VMM itself, not the Intel driver,
+  or the SR-IOV logic of the VMM, but rather that KVM emulates an older CPU
+  model for the guests, and this older CPU model does not support MSI-X
+  interrupts, which is a requirement for Intel SR-IOV.
 
-  NAPI (Rx polling mode) is supported in the ixgbe driver.  NAPI is enabled
-  by default in the driver.
+  If you wish to use the Intel 82576 or 82599-based controllers in SR-IOV mode
+  with KVM and a Microsoft Windows Server 2008 guest try the following
+  workaround. The workaround is to tell KVM to emulate a different model of CPU
+  when using qemu to create the KVM guest:

+                        RS485 SERIAL COMMUNICATIONS
+
+1. INTRODUCTION
+
+   EIA-485, also known as TIA/EIA-485 or RS-485, is a standard defining the
+   electrical characteristics of drivers and receivers for use in balanced
+   digital multipoint systems.
+   This standard is widely used for communications in industrial automation
+   because it can be used effectively over long distances and in electrically
+   noisy environments.
+
+2. HARDWARE-RELATED CONSIDERATIONS
+
+   Some CPUs/UARTs (e.g., Atmel AT91 or 16C950 UART) contain a built-in
+   half-duplex mode capable of automatically controlling line direction by
+   toggling RTS or DTR signals. That can be used to control external
+   half-duplex hardware like an RS485 transceiver or any RS232-connected
+   half-duplex devices like some modems.
+
+   For these microcontrollers, the Linux driver should be made capable of
+   working in both modes, and proper ioctls (see later) should be made
+   available at user-level to allow switching from one mode to the other, and
+   vice versa.
+
+3. DATA STRUCTURES ALREADY AVAILABLE IN THE KERNEL
+
+   The Linux kernel provides the serial_rs485 structure (see [1]) to handle
+   RS485 communications. This data structure is used to set and configure RS485
+   parameters in the platform data and in ioctls.
+
+   Any driver for devices capable of working both as RS232 and RS485 should
+   provide at least the following ioctls:
+
+    - TIOCSRS485 (typically associated with number 0x542F). This ioctl is used
+      to enable/disable RS485 mode from user-space
+
+    - TIOCGRS485 (typically associated with number 0x542E). This ioctl is used
+      to get RS485 mode from kernel-space (i.e., driver) to user-space.
+
+   In other words, the serial driver should contain a code similar to the next
+   one:
+
+	static struct uart_ops atmel_pops = {
+		/* ... */
+		.ioctl		= handle_ioctl,
+	};
+
+	static int handle_ioctl(struct uart_port *port,
+		unsigned int cmd,
+		unsigned long arg)
+	{
+		struct serial_rs485 rs485conf;
+
+		switch (cmd) {
+		case TIOCSRS485:
+			if (copy_from_user(&rs485conf,
+				(struct serial_rs485 *) arg,
+				sizeof(rs485conf)))
+					return -EFAULT;
+
+			/* ... */
+			break;
+
+		case TIOCGRS485:
+			if (copy_to_user((struct serial_rs485 *) arg,
+				...,
+				sizeof(rs485conf)))
+					return -EFAULT;
+			/* ... */
+			break;
+
+		/* ... */
+		}
+	}
+
+
+4. USAGE FROM USER-LEVEL
+
+   From user-level, RS485 configuration can be get/set using the previous
+   ioctls. For instance, to set RS485 you can use the following code:
+
+	#include <linux/serial.h>
+
+	/* Driver-specific ioctls: */
+	#define TIOCGRS485      0x542E
+	#define TIOCSRS485      0x542F
+
+	/* Open your specific device (e.g., /dev/mydevice): */
+	int fd = open ("/dev/mydevice", O_RDWR);
+	if (fd < 0) {
+		/* Error handling. See errno. */
+	}
+
+	struct serial_rs485 rs485conf;
+
+	/* Set RS485 mode: */
+	rs485conf.flags |= SER_RS485_ENABLED;
+
+	/* Set rts delay before send, if needed: */
+	rs485conf.flags |= SER_RS485_RTS_BEFORE_SEND;
+	rs485conf.delay_rts_before_send = ...;
+
+	/* Set rts delay after send, if needed: */
+	rs485conf.flags |= SER_RS485_RTS_AFTER_SEND;
+	rs485conf.delay_rts_after_send = ...;
+
+	if (ioctl (fd, TIOCSRS485, &rs485conf) < 0) {
+		/* Error handling. See errno. */
+	}
+
+	/* Use read() and write() syscalls here... */
+
+	/* Close the device when finished: */
+	if (close (fd) < 0) {
+		/* Error handling. See errno. */
+	}

+
+			Subsystem Trace Points: power
+
+The power tracing system captures events related to power transitions
+within the kernel. Broadly speaking there are three major subheadings:
+
+  o Power state switch which reports events related to suspend (S-states),
+     cpuidle (C-states) and cpufreq (P-states)
+  o System clock related changes
+  o Power domains related changes and transitions
+
+This document describes what each of the tracepoints is and why they
+might be useful.
+
+Cf. include/trace/events/power.h for the events definitions.
+
+1. Power state switch events
+============================
+
+1.1 New trace API
+-----------------
+
+A 'cpu' event class gathers the CPU-related events: cpuidle and
+cpufreq.
+
+cpu_idle		"state=%lu cpu_id=%lu"
+cpu_frequency		"state=%lu cpu_id=%lu"
+
+A suspend event is used to indicate the system going in and out of the
+suspend mode:
+
+machine_suspend		"state=%lu"
+
+
+Note: the value of '-1' or '4294967295' for state means an exit from the current state,
+i.e. trace_cpu_idle(4, smp_processor_id()) means that the system
+enters the idle state 4, while trace_cpu_idle(PWR_EVENT_EXIT, smp_processor_id())
+means that the system exits the previous idle state.
+
+The event which has 'state=4294967295' in the trace is very important to the user
+space tools which are using it to detect the end of the current state, and so to
+correctly draw the states diagrams and to calculate accurate statistics etc.
+
+1.2 DEPRECATED trace API
+------------------------
+
+A new Kconfig option CONFIG_EVENT_POWER_TRACING_DEPRECATED with the default value of
+'y' has been created. This allows the legacy trace power API to be used conjointly
+with the new trace API.
+The Kconfig option, the old trace API (in include/trace/events/power.h) and the
+old trace points will disappear in a future release (namely 2.6.41).
+
+power_start		"type=%lu state=%lu cpu_id=%lu"
+power_frequency		"type=%lu state=%lu cpu_id=%lu"
+power_end		"cpu_id=%lu"
+
+The 'type' parameter takes one of those macros:
+ . POWER_NONE	= 0,
+ . POWER_CSTATE	= 1,	/* C-State */
+ . POWER_PSTATE	= 2,	/* Fequency change or DVFS */
+
+The 'state' parameter is set depending on the type:
+ . Target C-state for type=POWER_CSTATE,
+ . Target frequency for type=POWER_PSTATE,
+
+power_end is used to indicate the exit of a state, corresponding to the latest
+power_start event.
+
+2. Clocks events
+================
+The clock events are used for clock enable/disable and for
+clock rate change.
+
+clock_enable		"%s state=%lu cpu_id=%lu"
+clock_disable		"%s state=%lu cpu_id=%lu"
+clock_set_rate		"%s state=%lu cpu_id=%lu"
+
+The first parameter gives the clock name (e.g. "gpio1_iclk").
+The second parameter is '1' for enable, '0' for disable, the target
+clock rate for set_rate.
+
+3. Power domains events
+=======================
+The power domain events are used for power domains transitions
+
+power_domain_target	"%s state=%lu cpu_id=%lu"
+
+The first parameter gives the power domain name (e.g. "mpu_pwrdm").
+The second parameter is the power domain target state.

-This is a driver for the CPiA PPC2 driven parallel connected
-Camera. For example the Creative WebcamII is CPiA driven.
-
-   ) [1]Peter Pregler, Linz 2000, published under the [2]GNU GPL
-
----------------------------------------------------------------------------
-
-USAGE:
-
-General:
-========
-
-1) Make sure you have created the video devices (/dev/video*):
-
-- if you have a recent MAKEDEV do a 'cd /dev;./MAKEDEV video'
-- otherwise do a:
-
-cd /dev
-mknod video0 c 81 0
-ln -s video0 video
-
-2) Compile the kernel (see below for the list of options to use),
-   configure your parport and reboot.
-
-3) If all worked well you should get messages similar
-   to the following (your versions may be different) on the console:
-
-V4L-Driver for Vision CPiA based cameras v0.7.4
-parport0: read2 timeout.
-parport0: Multimedia device, VLSI Vision Ltd PPC2
-Parallel port driver for Vision CPiA based camera
-  CPIA Version: 1.20 (2.0)
-  CPIA PnP-ID: 0553:0002:0100
-  VP-Version: 1.0 0100
-  1 camera(s) found
-
-
-As modules:
-===========
-
-Make sure you have selected the following kernel options (you can
-select all stuff as modules):
-
-The cpia-stuff is in the section 'Character devices -> Video For Linux'.
-
-CONFIG_PARPORT=m
-CONFIG_PARPORT_PC=m
-CONFIG_PARPORT_PC_FIFO=y
-CONFIG_PARPORT_1284=y
-CONFIG_VIDEO_DEV=m
-CONFIG_VIDEO_CPIA=m
-CONFIG_VIDEO_CPIA_PP=m
-
-For autoloading of all those modules you need to tell module-init-tools
-some stuff. Add the following line to your module-init-tools config-file
-(e.g. /etc/modprobe.conf or wherever your distribution does store that
-stuff):
-
-options parport_pc io=0x378 irq=7 dma=3
-alias char-major-81 cpia_pp
-
-The first line tells the dma/irq channels to use. Those _must_ match
-the settings of your BIOS. Do NOT simply use the values above.  See
-Documentation/parport.txt for more information about this. The second
-line associates the video-device file with the driver. Of cause you
-can also load the modules once upon boot (usually done in /etc/modules).
-
-Linked into the kernel:
-=======================
-
-Make sure you have selected the following kernel options. Note that
-you cannot compile the parport-stuff as modules and the cpia-driver
-statically (the other way round is okay though).
-
-The cpia-stuff is in the section 'Character devices -> Video For Linux'.
-
-CONFIG_PARPORT=y
-CONFIG_PARPORT_PC=y
-CONFIG_PARPORT_PC_FIFO=y
-CONFIG_PARPORT_1284=y
-CONFIG_VIDEO_DEV=y
-CONFIG_VIDEO_CPIA=y
-CONFIG_VIDEO_CPIA_PP=y
-
-To use DMA/irq you will need to tell the kernel upon boot time the
-hardware configuration of the parport. You can give the boot-parameter
-at the LILO-prompt or specify it in lilo.conf. I use the following
-append-line in lilo.conf:
-
-	append="parport=0x378,7,3"
-
-See Documentation/parport.txt for more information about the
-configuration of the parport and the values given above. Do not simply
-use the values given above.

-FEATURES:
-
-- mmap/read v4l-interface (but no overlay)
-- image formats: CIF/QCIF, SIF/QSIF, various others used by isabel;
-  note: all sizes except CIF/QCIF are implemented by clipping, i.e.
-  pixels are not uploaded from the camera
-- palettes: VIDEO_PALETTE_GRAY, VIDEO_PALETTE_RGB565, VIDEO_PALETTE_RGB555,
-  VIDEO_PALETTE_RGB24, VIDEO_PALETTE_RGB32, VIDEO_PALETTE_YUYV,
-  VIDEO_PALETTE_UYVY, VIDEO_PALETTE_YUV422
-- state information (color balance, exposure, ...) is preserved between
-  device opens
-- complete control over camera via proc-interface (_all_ camera settings are
-  supported), there is also a python-gtk application available for this [3]
-- works under SMP (but the driver is completely serialized and synchronous)
-  so you get no benefit from SMP, but at least it does not crash your box
-- might work for non-Intel architecture, let us know about this
-
----------------------------------------------------------------------------
-TESTED APPLICATIONS:
-
-- a simple test application based on Xt is available at [3]
-- another test-application based on gqcam-0.4 (uses GTK)
-- gqcam-0.6 should work
-- xawtv-3.x (also the webcam software)
-- xawtv-2.46
-- w3cam (cgi-interface and vidcat, e.g. you may try out 'vidcat  |xv
-  -maxpect -root -quit +noresetroot -rmode 5 -')
-- vic, the MBONE video conferencing tool (version 2.8ucl4-1)
-- isabel 3R4beta (barely working, but AFAICT all the problems are on
-  their side)
-- camserv-0.40
-
-See [3] for pointers to v4l-applications.
-
----------------------------------------------------------------------------
-KNOWN PROBLEMS:
-
-- some applications do not handle the image format correctly, you will
-  see strange horizontal stripes instead of a nice picture -> make sure
-  your application does use a supported image size or queries the driver
-  for the actually used size (reason behind this: the camera cannot
-  provide any image format, so if size NxM is requested the driver will
-  use a format to the closest fitting N1xM1, the application should now
-  query for this granted size, most applications do not).
-- all the todo ;)
-- if there is not enough light and the picture is too dark try to
-  adjust the SetSensorFPS setting, automatic frame rate adjustment
-  has its price
-- do not try out isabel 3R4beta (built 135), you will be disappointed
-
----------------------------------------------------------------------------
-TODO:
-
-- multiple camera support (struct camera or something) - This should work,
-  but hasn't been tested yet.
-- architecture independence?
-- SMP-safe asynchronous mmap interface
-- nibble mode for old parport interfaces
-- streaming capture, this should give a performance gain
-
----------------------------------------------------------------------------
-IMPLEMENTATION NOTES:
-
-The camera can act in two modes, streaming or grabbing. Right now a
-polling grab-scheme is used. Maybe interrupt driven streaming will be
-used for a asynchronous mmap interface in the next major release of the
-driver. This might give a better frame rate.

 4. Programming interface
 
-This driver conforms to video4linux and video4linux2, both can be used to
-use the driver. Since video4linux didn't provide adequate calls to fully
-use the cards' features, we've introduced several programming extensions,
-which are currently officially accepted in the 2.4.x branch of the kernel.
-These extensions are known as the v4l/mjpeg extensions. See zoran.h for
-details (structs/ioctls).

-The ioctls for that interface are as follows:
-
-BUZIOC_G_PARAMS
-BUZIOC_S_PARAMS
-
-Get and set the parameters of the buz. The user should always do a
-BUZIOC_G_PARAMS (with a struct buz_params) to obtain the default
-settings, change what he likes and then make a BUZIOC_S_PARAMS call.
-
-BUZIOC_REQBUFS
-
-Before being able to capture/playback, the user has to request
-the buffers he is wanting to use. Fill the structure
-zoran_requestbuffers with the size (recommended: 256*1024) and
-the number (recommended 32 up to 256). There are no such restrictions
-as for the Video for Linux buffers, you should LEAVE SUFFICIENT
-MEMORY for your system however, else strange things will happen ....
-On return, the zoran_requestbuffers structure contains number and
-size of the actually allocated buffers.
-You should use these numbers for doing a mmap of the buffers
-into the user space.
-The BUZIOC_REQBUFS ioctl also makes it happen, that the next mmap
-maps the MJPEG buffer instead of the V4L buffers.
-
-BUZIOC_QBUF_CAPT
-BUZIOC_QBUF_PLAY
-
-Queue a buffer for capture or playback. The first call also starts
-streaming capture. When streaming capture is going on, you may
-only queue further buffers or issue syncs until streaming
-capture is switched off again with a argument of -1 to
-a BUZIOC_QBUF_CAPT/BUZIOC_QBUF_PLAY ioctl.
-
-BUZIOC_SYNC
-
-Issue this ioctl when all buffers are queued. This ioctl will
-block until the first buffer becomes free for saving its
-data to disk (after BUZIOC_QBUF_CAPT) or for reuse (after BUZIOC_QBUF_PLAY).
-
-BUZIOC_G_STATUS
-
-Get the status of the input lines (video source connected/norm).
+This driver conforms to video4linux2. Support for V4L1 and for the custom

- * ARMv6 Performance counter handling code.
- *
- * ARMv6 has 2 configurable performance counters and a single cycle counter.
- * They all share a single reset bit but can be written to zero so we can use
- * that for a reset.
- *
- * The counters can't be individually enabled or disabled so when we remove
- * one event and replace it with another we could get spurious counts from the
- * wrong event. However, we can take advantage of the fact that the
- * performance counters can export events to the event bus, and the event bus
- * itself can be monitored. This requires that we *don't* export the events to
- * the event bus. The procedure for disabling a configurable counter is:
- *	- change the counter to count the ETMEXTOUT[0] signal (0x20). This
- *	  effectively stops the counter from counting.
- *	- disable the counter's interrupt generation (each counter has it's
- *	  own interrupt enable bit).
- * Once stopped, the counter value can be written as 0 to reset.
- *
- * To enable a counter:
- *	- enable the counter's interrupt generation.
- *	- set the new event type.
- *
- * Note: the dedicated cycle counter only counts cycles and can't be
- * enabled/disabled independently of the others. When we want to disable the
- * cycle counter, we have to just disable the interrupt reporting and start
- * ignoring that counter. When re-enabling, we have to reset the value and
- * enable the interrupt.

+/*
+ * ARMv6 Performance counter handling code.
+ *
+ * Copyright (C) 2009 picoChip Designs, Ltd., Jamie Iles
+ *
+ * ARMv6 has 2 configurable performance counters and a single cycle counter.
+ * They all share a single reset bit but can be written to zero so we can use
+ * that for a reset.
+ *
+ * The counters can't be individually enabled or disabled so when we remove
+ * one event and replace it with another we could get spurious counts from the
+ * wrong event. However, we can take advantage of the fact that the
+ * performance counters can export events to the event bus, and the event bus
+ * itself can be monitored. This requires that we *don't* export the events to
+ * the event bus. The procedure for disabling a configurable counter is:
+ *	- change the counter to count the ETMEXTOUT[0] signal (0x20). This
+ *	  effectively stops the counter from counting.
+ *	- disable the counter's interrupt generation (each counter has it's
+ *	  own interrupt enable bit).
+ * Once stopped, the counter value can be written as 0 to reset.
+ *
+ * To enable a counter:
+ *	- enable the counter's interrupt generation.
+ *	- set the new event type.
+ *
+ * Note: the dedicated cycle counter only counts cycles and can't be
+ * enabled/disabled independently of the others. When we want to disable the
+ * cycle counter, we have to just disable the interrupt reporting and start
+ * ignoring that counter. When re-enabling, we have to reset the value and
+ * enable the interrupt.

+	 * As per Errata i520, in some cases, user will not be able to

+	 * This situation occurs while the warm-reset happens during a read
+	 * access to DDR memory. In that particular condition, DDR memory
+	 * does not respond to a corrupted read command due to the warm
+	 * reset occurrence but SDRC is waiting for read completion.
+	 * SDRC is not sensitive to the warm reset, but the interconnect is
+	 * reset on the fly, thus causing a misalignment between SDRC logic,
+	 * interconnect logic and DDR memory state.
+	 * WORKAROUND:
+	 * Steps to perform before a Warm reset is trigged:
+	 * 1. enable self-refresh on idle request
+	 * 2. put SDRC in idle
+	 * 3. wait until SDRC goes to idle
+	 * 4. generate SW reset (Global SW reset)
+	 *
+	 * Steps to be performed after warm reset occurs (in bootloader):
+	 * if HW warm reset is the source, apply below steps before any
+	 * accesses to SDRAM:
+	 * 1. Reset SMS and SDRC and wait till reset is complete
+	 * 2. Re-initialize SMS, SDRC and memory
+	 *
+	 * NOTE: Above work around is required only if arch reset is implemented
+	 * using Global SW reset(GLOBAL_SW_RST). DPLL3 reset does not need
+	 * the WA since it resets SDRC as well as part of cold reset.

+ * This is rather complicated for humans and ugly to verify, but for a machine
+ * it's OK.  Still more as it is usually only applied to constants.  The upsides
+ * on using this approach are:
+ *
+ *  - same mapping on all i.MX machines
+ *  - works for assembler, too
+ *  - no need to nurture #defines for virtual addresses
+ *
+ * The downside it, it's hard to verify (but I have a script for that).
+ *
+ * Obviously this needs to be injective for each SoC.  In general it maps the
+ * whole address space to [0xf4000000, 0xf5ffffff].  So [0xf6000000,0xfeffffff]

+ * This structure partially defines a queue of empty buffers which have been
+ * obtained via requests to the IPP.  (The elements of the queue are packet
+ * handles, which are transformed into a full netio_pkt_t when the buffer is
+ * retrieved.)  The queue as a whole is written to by an interrupt handler and
+ * read by non-interrupt code; this data structure is what's touched by the
+ * interrupt handler.  The other parts of the queue state, the read offset and
+ * requested write offset, are kept in user space, not in hypervisor space, so
+ * they are in a separate data structure.
+ *
+ * The read offset (__buffer_read in the user part of the queue structure)
+ * points to the next buffer to be read. When the read offset is equal to the
+ * write offset, the queue is empty; therefore the queue must contain one more
+ * slot than the required maximum queue size.
+ *
+ * The requested write offset (__buffer_requested_write in the user part of
+ * the queue structure) points to the slot which will hold the next buffer we
+ * request from the IPP, once we get around to sending such a request.  When
+ * the requested write offset is equal to the write offset, no requests for
+ * new buffers are outstanding; when the requested write offset is one greater
+ * than the read offset, no more requests may be sent.
+ *
+ * Note that, unlike the packet_queue, the buffer_queue places incoming
+ * buffers at decreasing addresses.  This makes the check for "is it time to
+ * wrap the buffer pointer" cheaper in the assembly code which receives new
+ * buffers, and means that the value which defines the queue size,
+ * __last_buffer, is different than in the packet queue.  Also, the offset
+ * used in the packet_queue is already scaled by the size of a packet; here we
+ * use unscaled slot indices for the offsets.  (These differences are
+ * historical, and in the future it's possible that the packet_queue will look
+ * more like this queue.)

+/**
+ * @brief An object for specifying the characteristics of NetIO communication
+ * endpoint.
+ *
+ * @ingroup setup
+ *
+ * The @ref netio_input_register() function uses this structure to define
+ * how an application tile will communicate with an IPP.
+ *
+ *
+ * Future updates to NetIO may add new members to this structure,
+ * which can affect the success of the registration operation.  Thus,
+ * if dynamically initializing the structure, applications are urged to
+ * zero it out first, for example:
+ *
+ * @code
+ * netio_input_config_t config;
+ * memset(&config, 0, sizeof (config));
+ * config.flags = NETIO_RECV | NETIO_XMIT_CSUM | NETIO_TAG_NONE;
+ * config.num_receive_packets = NETIO_MAX_RECEIVE_PKTS;
+ * config.queue_id = 0;
+ *     .
+ *     .
+ *     .
+ * @endcode
+ *
+ * since that guarantees that any unused structure members, including
+ * members which did not exist when the application was first developed,
+ * will not have unexpected values.
+ *
+ * If statically initializing the structure, we strongly recommend use of
+ * C99-style named initializers, for example:
+ *
+ * @code
+ * netio_input_config_t config = {
+ *    .flags = NETIO_RECV | NETIO_XMIT_CSUM | NETIO_TAG_NONE,
+ *    .num_receive_packets = NETIO_MAX_RECEIVE_PKTS,
+ *    .queue_id = 0,
+ * },
+ * @endcode
+ *
+ * instead of the old-style structure initialization:
+ *
+ * @code
+ * // Bad example! Currently equivalent to the above, but don't do this.
+ * netio_input_config_t config = {
+ *    NETIO_RECV | NETIO_XMIT_CSUM | NETIO_TAG_NONE, NETIO_MAX_RECEIVE_PKTS, 0
+ * },
+ * @endcode
+ *
+ * since the C99 style requires no changes to the code if elements of the
+ * config structure are rearranged.  (It also makes the initialization much
+ * easier to understand.)
+ *
+ * Except for items which address a particular tile's transmit or receive
+ * characteristics, such as the ::NETIO_RECV flag, applications are advised
+ * to specify the same set of configuration data on all registrations.
+ * This prevents differing results if multiple tiles happen to do their
+ * registration operations in a different order on different invocations of
+ * the application.  This is particularly important for things like link
+ * management flags, and buffer size and homing specifications.
+ *
+ * Unless the ::NETIO_FIXED_BUFFER_VA flag is specified in flags, the NetIO
+ * buffer pool is automatically created and mapped into the application's
+ * virtual address space at an address chosen by the operating system,
+ * using the common memory (cmem) facility in the Tilera Multicore
+ * Components library.  The cmem facility allows multiple processes to gain
+ * access to shared memory which is mapped into each process at an
+ * identical virtual address.  In order for this to work, the processes
+ * must have a common ancestor, which must create the common memory using
+ * tmc_cmem_init().
+ *
+ * In programs using the iLib process creation API, or in programs which use
+ * only one process (which include programs using the pthreads library),
+ * tmc_cmem_init() is called automatically.  All other applications
+ * must call it explicitly, before any child processes which might call
+ * netio_input_register() are created.
+ */
+typedef struct
+{
+  /** Registration characteristics.
+
+      This value determines several characteristics of the registration;
+      flags for different types of behavior are ORed together to make the
+      final flag value.  Generally applications should specify exactly
+      one flag from each of the following categories:
+
+      - Whether the application will be receiving packets on this queue
+        (::NETIO_RECV or ::NETIO_NO_RECV).
+
+      - Whether the application will be transmitting packets on this queue,
+        and if so, whether it will request egress checksum calculation
+        (::NETIO_XMIT, ::NETIO_XMIT_CSUM, or ::NETIO_NO_XMIT).  It is
+        legal to call netio_get_buffer() without one of the XMIT flags,
+        as long as ::NETIO_RECV is specified; in this case, the retrieved
+        buffers must be passed to another tile for transmission.
+
+      - Whether the application expects any vendor-specific tags in
+        its packets' L2 headers (::NETIO_TAG_NONE, ::NETIO_TAG_BRCM,
+        or ::NETIO_TAG_MRVL).  This must match the configuration of the
+        target IPP.
+
+      To accommodate applications written to previous versions of the NetIO
+      interface, none of the flags above are currently required; if omitted,
+      NetIO behaves more or less as if ::NETIO_RECV | ::NETIO_XMIT_CSUM |
+      ::NETIO_TAG_NONE were used.  However, explicit specification of
+      the relevant flags allows NetIO to do a better job of resource
+      allocation, allows earlier detection of certain configuration errors,
+      and may enable advanced features or higher performance in the future,
+      so their use is strongly recommended.
+
+      Note that specifying ::NETIO_NO_RECV along with ::NETIO_NO_XMIT
+      is a special case, intended primarily for use by programs which
+      retrieve network statistics or do link management operations.
+      When these flags are both specified, the resulting queue may not
+      be used with NetIO routines other than netio_get(), netio_set(),
+      and netio_input_unregister().  See @ref link for more information
+      on link management.
+
+      Other flags are optional; their use is described below.

+  uint64_t total_buffer_size;
+
+  /** Buffer placement weighting factors.
+
+      This array specifies the relative amount of buffering to place
+      on each of the available Linux NUMA nodes.  This array is
+      indexed by the NUMA node, and the values in the array are
+      proportional to the amount of buffer space to allocate on that
+      node.
+
+      If memory striping is enabled in the Hypervisor, then there is
+      only one logical NUMA node (node 0). In that case, NetIO will by
+      default ignore the suggested buffer node weights, and buffers
+      will be striped across the physical memory controllers. See
+      UG209 System Programmer's Guide for a description of the
+      hypervisor option that controls memory striping.
+
+      If memory striping is disabled, then there are up to four NUMA
+      nodes, corresponding to the four DDRAM controllers in the TILE
+      processor architecture.  See UG100 Tile Processor Architecture
+      Overview for a diagram showing the location of each of the DDRAM
+      controllers relative to the tile array.
+
+      For instance, if memory striping is disabled, the following
+      configuration strucure:
+
+      @code
+      netio_input_config_t config = {
+            .
+            .
+            .
+        .total_buffer_size = 4 * 16 * 1024 * 1024;
+        .buffer_node_weights = { 1, 0, 1, 0 },
+      },
+      @endcode
+
+      would result in 32 MB of buffers being placed on controller 0, and
+      32 MB on controller 2.  (Since buffers are allocated in units of
+      16 MB, some sets of weights will not be able to be matched exactly.)
+
+      For the weights to be effective, @ref total_buffer_size must be
+      nonzero.  If @ref total_buffer_size is zero, causing the default
+      32 MB of buffer space to be used, then any specified weights will
+      be ignored, and buffers will positioned as they were in previous
+      versions of NetIO:
+
+      - For xgbe/0 and gbe/0, 16 MB of buffers will be placed on controller 1,
+        and the other 16 MB will be placed on controller 2.
+
+      - For xgbe/1 and gbe/1, 16 MB of buffers will be placed on controller 2,
+        and the other 16 MB will be placed on controller 3.
+
+      If @ref total_buffer_size is nonzero, but all weights are zero,
+      then all buffer space will be allocated on Linux NUMA node zero.
+
+      By default, the specified buffer placement is treated as a hint;
+      if sufficient free memory is not available on the specified
+      controllers, the buffers will be allocated elsewhere.  However,
+      if the ::NETIO_STRICT_HOMING flag is specified in @ref flags, then a
+      failure to allocate buffer space exactly as requested will cause the
+      registration operation to fail with an error of ::NETIO_CANNOT_HOME.
+
+      Note that maximal network performance cannot be achieved with
+      only one memory controller.

+      Modifying this value is generally only helpful when using @ref

+ * Since P4 has quite the different architecture of

+ *
+ * 1) Since both ESCR and CCCR registers have only low
+ *    32 bits valuable, we pack them into a single 64 bit
+ *    configuration. Low 32 bits of such config correspond
+ *    to low 32 bits of CCCR register and high 32 bits
+ *    correspond to low 32 bits of ESCR register.
+ *
+ * 2) The meaning of every bit of such config field can
+ *    be found in Intel SDM but it should be noted that
+ *    we "borrow" some reserved bits for own usage and
+ *    clean them or set to a proper value when we do
+ *    a real write to hardware registers.
+ *
+ * 3) The format of bits of config is the following

-   Instructions for use
-   --------------------
+   For usage instructions, please refer to:
 
-   1) Map a Linux block device to an existing rbd image.
-
-      Usage: <mon ip addr> <options> <pool name> <rbd image name> [snap name]
-
-      $ echo "192.168.0.1 name=admin rbd foo" > /sys/class/rbd/add
-
-      The snapshot name can be "-" or omitted to map the image read/write.
-
-   2) List all active blkdev<->object mappings.
-
-      In this example, we have performed step #1 twice, creating two blkdevs,
-      mapped to two separate rados objects in the rados rbd pool
-
-      $ cat /sys/class/rbd/list
-      #id     major   client_name     pool    name    snap    KB
-      0       254     client4143      rbd     foo     -      1024000
-
-      The columns, in order, are:
-      - blkdev unique id
-      - blkdev assigned major
-      - rados client id
-      - rados pool name
-      - rados block device name
-      - mapped snapshot ("-" if none)
-      - device size in KB
-
-
-   3) Create a snapshot.
-
-      Usage: <blkdev id> <snapname>
-
-      $ echo "0 mysnap" > /sys/class/rbd/snap_create
-
-
-   4) Listing a snapshot.
-
-      $ cat /sys/class/rbd/snaps_list
-      #id     snap    KB
-      0       -       1024000 (*)
-      0       foo     1024000
-
-      The columns, in order, are:
-      - blkdev unique id
-      - snapshot name, '-' means none (active read/write version)
-      - size of device at time of snapshot
-      - the (*) indicates this is the active version
-
-   5) Rollback to snapshot.
-
-      Usage: <blkdev id> <snapname>
-
-      $ echo "0 mysnap" > /sys/class/rbd/snap_rollback
-
-
-   6) Mapping an image using snapshot.
-
-      A snapshot mapping is read-only. This is being done by passing
-      snap=<snapname> to the options when adding a device.
-
-      $ echo "192.168.0.1 name=admin,snap=mysnap rbd foo" > /sys/class/rbd/add
-
-
-   7) Remove an active blkdev<->rbd image mapping.
-
-      In this example, we remove the mapping with blkdev unique id 1.
-
-      $ echo 1 > /sys/class/rbd/remove
-
-
-   NOTE:  The actual creation and deletion of rados objects is outside the scope
-   of this driver.

+ * A CAN frame has a can_id (11 bit standard frame format OR 29 bit extended
+ * frame format) a data length code (can_dlc) which can be from 0 to 8
+ * and up to <can_dlc> data bytes as payload.
+ * Additionally a CAN frame may become a remote transmission frame if the
+ * RTR-bit is set. This causes another ECU to send a CAN frame with the
+ * given can_id.
+ *
+ * The SLCAN ASCII representation of these different frame types is:
+ * <type> <id> <dlc> <data>*
+ *
+ * Extended frames (29 bit) are defined by capital characters in the type.
+ * RTR frames are defined as 'r' types - normal frames have 't' type:
+ * t => 11 bit data frame
+ * r => 11 bit RTR frame
+ * T => 29 bit data frame
+ * R => 29 bit RTR frame
+ *
+ * The <id> is 3 (standard) or 8 (extended) bytes in ASCII Hex (base64).
+ * The <dlc> is a one byte ASCII number ('0' - '8')
+ * The <data> section has at much ASCII Hex bytes as defined by the <dlc>
+ *
+ * Examples:
+ *
+ * t1230 : can_id 0x123, can_dlc 0, no data
+ * t4563112233 : can_id 0x456, can_dlc 3, data 0x11 0x22 0x33
+ * T12ABCDEF2AA55 : extended can_id 0x12ABCDEF, can_dlc 2, data 0xAA 0x55
+ * r1230 : can_id 0x123, can_dlc 0, no data, remote transmission request

  *
  * Notes on locking strategy:
  *
- * Most NIC registers require 16-byte (or 8-byte, for SRAM) atomic writes
- * which necessitates locking.
- * Under normal operation few writes to NIC registers are made and these
- * registers (EVQ_RPTR_REG, RX_DESC_UPD_REG and TX_DESC_UPD_REG) are special
- * cased to allow 4-byte (hence lockless) accesses.
+ * Most CSRs are 128-bit (oword) and therefore cannot be read or
+ * written atomically.  Access from the host is buffered by the Bus
+ * Interface Unit (BIU).  Whenever the host reads from the lowest
+ * address of such a register, or from the address of a different such
+ * register, the BIU latches the register's value.  Subsequent reads
+ * from higher addresses of the same register will read the latched
+ * value.  Whenever the host writes part of such a register, the BIU
+ * collects the written value and does not write to the underlying
+ * register until all 4 dwords have been written.  A similar buffering
+ * scheme applies to host access to the NIC's 64-bit SRAM.
  *
- * It *is* safe to write to these 4-byte registers in the middle of an
- * access to an 8-byte or 16-byte register.  We therefore use a
- * spinlock to protect accesses to the larger registers, but no locks
- * for the 4-byte registers.
+ * Access to different CSRs and 64-bit SRAM words must be serialised,
+ * since interleaved access can result in lost writes or lost
+ * information from read-to-clear fields.  We use efx_nic::biu_lock
+ * for this.  (We could use separate locks for read and write, but
+ * this is not normally a performance bottleneck.)
  *
- * A write barrier is needed to ensure that DW3 is written after DW0/1/2
- * due to the way the 16byte registers are "collected" in the BIU.
+ * The DMA descriptor pointers (RX_DESC_UPD and TX_DESC_UPD) are
+ * 128-bit but are special-cased in the BIU to avoid the need for
+ * locking in the host:
  *
- * We also lock when carrying out reads, to ensure consistency of the
- * data (made possible since the BIU reads all 128 bits into a cache).
- * Reads are very rare, so this isn't a significant performance
- * impact.  (Most data transferred from NIC to host is DMAed directly
- * into host memory).
- *
- * I/O BAR access uses locks for both reads and writes (but is only provided
- * for testing purposes).
+ * - They are write-only.
+ * - The semantics of writing to these registers are such that
+ *   replacing the low 96 bits with zero does not affect functionality.
+ * - If the host writes to the last dword address of such a register
+ *   (i.e. the high 32 bits) the underlying register will always be
+ *   written.  If the collector does not hold values for the low 96
+ *   bits of the register, they will be written as zero.  Writing to
+ *   the last qword does not have this effect and must not be done.
+ * - If the host writes to the address of any other part of such a
+ *   register while the collector already holds values for some other
+ *   register, the write is discarded and the collector maintains its
+ *   current state.

+ * First, "tile_net_init_module()" initializes all four "devices" which

+ *
+ * Then, "ifconfig DEVICE up" calls "tile_net_open()", which analyzes
+ * the network cpus, then uses "tile_net_open_aux()" to initialize
+ * LIPP/LEPP, and then uses "tile_net_open_inner()" to register all
+ * the tiles, provide buffers to LIPP, allow ingress to start, and
+ * turn on hypervisor interrupt handling (and NAPI) on all tiles.
+ *
+ * If registration fails due to the link being down, then "retry_work"
+ * is used to keep calling "tile_net_open_inner()" until it succeeds.
+ *
+ * If "ifconfig DEVICE down" is called, it uses "tile_net_stop()" to
+ * stop egress, drain the LIPP buffers, unregister all the tiles, stop
+ * LIPP/LEPP, and wipe the LEPP queue.
+ *
+ * We start out with the ingress interrupt enabled on each CPU.  When
+ * this interrupt fires, we disable it, and call "napi_schedule()".
+ * This will cause "tile_net_poll()" to be called, which will pull
+ * packets from the netio queue, filtering them out, or passing them
+ * to "netif_receive_skb()".  If our budget is exhausted, we will
+ * return, knowing we will be called again later.  Otherwise, we
+ * reenable the ingress interrupt, and call "napi_complete()".
+ *
+ *
+ * NOTE: The use of "native_driver" ensures that EPP exists, and that
+ * "epp_sendv" is legal, and that "LIPP" is being used.
+ *
+ * NOTE: Failing to free completions for an arbitrarily long time
+ * (which is defined to be illegal) does in fact cause bizarre
+ * problems.  The "egress_timer" helps prevent this from happening.

- * The iwl_eeprom_band definitions below provide the mapping from the
- * EEPROM contents to the specific channel number supported for each
- * band.
- *
- * For example, iwl_priv->eeprom.band_3_channels[4] from the band_3
- * definition below maps to physical channel 42 in the 5.2GHz spectrum.
- * The specific geography and calibration information for that channel
- * is contained in the eeprom map itself.
- *
- * During init, we copy the eeprom information and channel map
- * information into priv->channel_info_24/52 and priv->channel_map_24/52
- *
- * channel_map_24/52 provides the index in the channel_info array for a
- * given channel.  We have to have two separate maps as there is channel
- * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
- * band_2
- *
- * A value of 0xff stored in the channel_map indicates that the channel
- * is not supported by the hardware at all.
- *
- * A value of 0xfe in the channel_map indicates that the channel is not
- * valid for Tx with the current hardware.  This means that
- * while the system can tune and receive on a given channel, it may not
- * be able to associate or transmit any frames on that
- * channel.  There is no corresponding channel information for that

- * expired.  When the queue read_ptr is at the same place, the timer is
- * shorten to 100mSecs.  This is

- *      2) to detect the stuck queues quicker before the station and AP can
- *      disassociate each other.
- *
- * This function monitors all the tx queues and recover from it if any
- * of the queues are stuck.
- * 1. It first check the cmd queue for stuck conditions.  If it is stuck,
- *      it will recover by resetting the firmware and return.
- * 2. Then, it checks for station association.  If it associates it will check
- *      other queues.  If any queue is stuck, it will recover by resetting
- *      the firmware.
- * Note: It the number of times the queue read_ptr to be at the same place to

+ *	notes by areas that may need addressing
+ * o	Some of the GPIO naming/setup assumptions may need revisiting if

 	The only goal of this restrictions was that all data
-	fit into one 4K page :-). Struct sfq_sched_data is
-	organized in anti-cache manner: all the data for a bucket
-	are scattered over different locations. This is not good,

- * Debugging code used by link routines only

- * allow the output from multiple links to be intermixed.  For this reason
- * routines of the form "dbg_link_XXX()" have been created that will capture
- * debug info into a link's personal print buffer, which can then be dumped
- * into the TIPC system log (TIPC_LOG) upon request.
- *
- * To enable per-link debugging, use LINK_LOG_BUF_SIZE to specify the size
- * of the print buffer used by each link.  If LINK_LOG_BUF_SIZE is set to 0,
- * the dbg_link_XXX() routines simply send their output to the standard
- * debug print buffer (DBG_OUTPUT), if it has been defined; this can be useful
- * when there is only a single link in the system being debugged.
- *
- * Notes:
- * - When enabled, LINK_LOG_BUF_SIZE should be set to at least TIPC_PB_MIN_SIZE
- * - "l_ptr" must be valid when using dbg_link_XXX() macros

+DESCRIPTION
+-----------
+This command reads the input file and displays the trace recorded.
+
+There are several variants of perf script:
+
+  'perf script' to see a detailed trace of the workload that was
+  recorded.
+
+  You can also run a set of pre-canned scripts that aggregate and
+  summarize the raw trace data in various ways (the list of scripts is
+  available via 'perf script -l').  The following variants allow you to
+  record and run those scripts:
+
+  'perf script record <script> <command>' to record the events required
+  for 'perf script report'.  <script> is the name displayed in the
+  output of 'perf script --list' i.e. the actual script name minus any
+  language extension.  If <command> is not specified, the events are
+  recorded using the -a (system-wide) 'perf record' option.
+
+  'perf script report <script> [args]' to run and display the results
+  of <script>.  <script> is the name displayed in the output of 'perf
+  trace --list' i.e. the actual script name minus any language
+  extension.  The perf.data output from a previous run of 'perf script
+  record <script>' is used and should be present for this command to
+  succeed.  [args] refers to the (mainly optional) args expected by
+  the script.
+
+  'perf script <script> <required-script-args> <command>' to both
+  record the events required for <script> and to run the <script>
+  using 'live-mode' i.e. without writing anything to disk.  <script>
+  is the name displayed in the output of 'perf script --list' i.e. the
+  actual script name minus any language extension.  If <command> is
+  not specified, the events are recorded using the -a (system-wide)
+  'perf record' option.  If <script> has any required args, they
+  should be specified before <command>.  This mode doesn't allow for
+  optional script args to be specified; if optional script args are
+  desired, they can be specified using separate 'perf script record'
+  and 'perf script report' commands, with the stdout of the record step
+  piped to the stdin of the report script, using the '-o -' and '-i -'
+  options of the corresponding commands.
+
+  'perf script <top-script>' to both record the events required for
+  <top-script> and to run the <top-script> using 'live-mode'
+  i.e. without writing anything to disk.  <top-script> is the name
+  displayed in the output of 'perf script --list' i.e. the actual
+  script name minus any language extension; a <top-script> is defined
+  as any script name ending with the string 'top'.
+
+  [<record-options>] can be passed to the record steps of 'perf script
+  record' and 'live-mode' variants; this isn't possible however for
+  <top-script> 'live-mode' or 'perf script report' variants.
+
+  See the 'SEE ALSO' section for links to language-specific
+  information on how to write and run your own trace scripts.
