+What:		legacy isochronous ABI of raw1394 (1st generation iso ABI)
+Date:		June 2007 (scheduled), removed in kernel v2.6.23
+Contact:	linux1394-devel@lists.sourceforge.net
+Description:
+	The two request types RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN have
+	been deprecated for quite some time.  They are very inefficient as they
+	come with high interrupt load and several layers of callbacks for each
+	packet.  Because of these deficiencies, the video1394 and dv1394 drivers
+	and the 3rd-generation isochronous ABI in raw1394 (rawiso) were created.
+
+Users:
+	libraw1394 users via the long deprecated API raw1394_iso_write,
+	raw1394_start_iso_write, raw1394_start_iso_rcv, raw1394_stop_iso_rcv
+
+	libdc1394, which optionally uses these old libraw1394 calls
+	alternatively to the more efficient video1394 ABI

+            The Spidernet Device Driver
+            ===========================
+
+Written by Linas Vepstas <linas@austin.ibm.com>
+
+Version of 7 June 2007
+
+Abstract
+========
+This document sketches the structure of portions of the spidernet
+device driver in the Linux kernel tree. The spidernet is a gigabit
+ethernet device built into the Toshiba southbridge commonly used
+in the SONY Playstation 3 and the IBM QS20 Cell blade.
+
+The Structure of the RX Ring.
+=============================
+The receive (RX) ring is a circular linked list of RX descriptors,
+together with three pointers into the ring that are used to manage its
+contents.
+
+The elements of the ring are called "descriptors" or "descrs"; they
+describe the received data. This includes a pointer to a buffer
+containing the received data, the buffer size, and various status bits.
+
+There are three primary states that a descriptor can be in: "empty",
+"full" and "not-in-use".  An "empty" or "ready" descriptor is ready
+to receive data from the hardware. A "full" descriptor has data in it,
+and is waiting to be emptied and processed by the OS. A "not-in-use"
+descriptor is neither empty or full; it is simply not ready. It may
+not even have a data buffer in it, or is otherwise unusable.
+
+During normal operation, on device startup, the OS (specifically, the
+spidernet device driver) allocates a set of RX descriptors and RX
+buffers. These are all marked "empty", ready to receive data. This
+ring is handed off to the hardware, which sequentially fills in the
+buffers, and marks them "full". The OS follows up, taking the full
+buffers, processing them, and re-marking them empty.
+
+This filling and emptying is managed by three pointers, the "head"
+and "tail" pointers, managed by the OS, and a hardware current
+descriptor pointer (GDACTDPA). The GDACTDPA points at the descr
+currently being filled. When this descr is filled, the hardware
+marks it full, and advances the GDACTDPA by one.  Thus, when there is
+flowing RX traffic, every descr behind it should be marked "full",
+and everything in front of it should be "empty".  If the hardware
+discovers that the current descr is not empty, it will signal an
+interrupt, and halt processing.
+
+The tail pointer tails or trails the hardware pointer. When the
+hardware is ahead, the tail pointer will be pointing at a "full"
+descr. The OS will process this descr, and then mark it "not-in-use",
+and advance the tail pointer.  Thus, when there is flowing RX traffic,
+all of the descrs in front of the tail pointer should be "full", and
+all of those behind it should be "not-in-use". When RX traffic is not
+flowing, then the tail pointer can catch up to the hardware pointer.
+The OS will then note that the current tail is "empty", and halt
+processing.
+
+The head pointer (somewhat mis-named) follows after the tail pointer.
+When traffic is flowing, then the head pointer will be pointing at
+a "not-in-use" descr. The OS will perform various housekeeping duties
+on this descr. This includes allocating a new data buffer and
+dma-mapping it so as to make it visible to the hardware. The OS will
+then mark the descr as "empty", ready to receive data. Thus, when there
+is flowing RX traffic, everything in front of the head pointer should
+be "not-in-use", and everything behind it should be "empty". If no
+RX traffic is flowing, then the head pointer can catch up to the tail
+pointer, at which point the OS will notice that the head descr is
+"empty", and it will halt processing.
+
+Thus, in an idle system, the GDACTDPA, tail and head pointers will
+all be pointing at the same descr, which should be "empty". All of the
+other descrs in the ring should be "empty" as well.
+
+The show_rx_chain() routine will print out the the locations of the
+GDACTDPA, tail and head pointers. It will also summarize the contents
+of the ring, starting at the tail pointer, and listing the status
+of the descrs that follow.
+
+A typical example of the output, for a nearly idle system, might be
+
+net eth1: Total number of descrs=256
+net eth1: Chain tail located at descr=20
+net eth1: Chain head is at 20
+net eth1: HW curr desc (GDACTDPA) is at 21
+net eth1: Have 1 descrs with stat=x40800101
+net eth1: HW next desc (GDACNEXTDA) is at 22
+net eth1: Last 255 descrs with stat=xa0800000
+
+In the above, the hardware has filled in one descr, number 20. Both
+head and tail are pointing at 20, because it has not yet been emptied.
+Meanwhile, hw is pointing at 21, which is free.
+
+The "Have nnn decrs" refers to the descr starting at the tail: in this
+case, nnn=1 descr, starting at descr 20. The "Last nnn descrs" refers
+to all of the rest of the descrs, from the last status change. The "nnn"
+is a count of how many descrs have exactly the same status.
+
+The status x4... corresponds to "full" and status xa... corresponds
+to "empty". The actual value printed is RXCOMST_A.
+
+In the device driver source code, a different set of names are
+used for these same concepts, so that
+
+"empty" == SPIDER_NET_DESCR_CARDOWNED == 0xa
+"full"  == SPIDER_NET_DESCR_FRAME_END == 0x4
+"not in use" == SPIDER_NET_DESCR_NOT_IN_USE == 0xf
+
+
+The RX RAM full bug/feature
+===========================
+
+As long as the OS can empty out the RX buffers at a rate faster than
+the hardware can fill them, there is no problem. If, for some reason,
+the OS fails to empty the RX ring fast enough, the hardware GDACTDPA
+pointer will catch up to the head, notice the not-empty condition,
+ad stop. However, RX packets may still continue arriving on the wire.
+The spidernet chip can save some limited number of these in local RAM.
+When this local ram fills up, the spider chip will issue an interrupt
+indicating this (GHIINT0STS will show ERRINT, and the GRMFLLINT bit
+will be set in GHIINT1STS).  When the RX ram full condition occurs,
+a certain bug/feature is triggered that has to be specially handled.
+This section describes the special handling for this condition.
+
+When the OS finally has a chance to run, it will empty out the RX ring.
+In particular, it will clear the descriptor on which the hardware had
+stopped. However, once the hardware has decided that a certain
+descriptor is invalid, it will not restart at that descriptor; instead
+it will restart at the next descr. This potentially will lead to a
+deadlock condition, as the tail pointer will be pointing at this descr,
+which, from the OS point of view, is empty; the OS will be waiting for
+this descr to be filled. However, the hardware has skipped this descr,
+and is filling the next descrs. Since the OS doesn't see this, there
+is a potential deadlock, with the OS waiting for one descr to fill,
+while the hardware is waiting for a different set of descrs to become
+empty.
+
+A call to show_rx_chain() at this point indicates the nature of the
+problem. A typical print when the network is hung shows the following:
+
+net eth1: Spider RX RAM full, incoming packets might be discarded!
+net eth1: Total number of descrs=256
+net eth1: Chain tail located at descr=255
+net eth1: Chain head is at 255
+net eth1: HW curr desc (GDACTDPA) is at 0
+net eth1: Have 1 descrs with stat=xa0800000
+net eth1: HW next desc (GDACNEXTDA) is at 1
+net eth1: Have 127 descrs with stat=x40800101
+net eth1: Have 1 descrs with stat=x40800001
+net eth1: Have 126 descrs with stat=x40800101
+net eth1: Last 1 descrs with stat=xa0800000
+
+Both the tail and head pointers are pointing at descr 255, which is
+marked xa... which is "empty". Thus, from the OS point of view, there
+is nothing to be done. In particular, there is the implicit assumption
+that everything in front of the "empty" descr must surely also be empty,
+as explained in the last section. The OS is waiting for descr 255 to
+become non-empty, which, in this case, will never happen.
+
+The HW pointer is at descr 0. This descr is marked 0x4.. or "full".
+Since its already full, the hardware can do nothing more, and thus has
+halted processing. Notice that descrs 0 through 254 are all marked
+"full", while descr 254 and 255 are empty. (The "Last 1 descrs" is
+descr 254, since tail was at 255.) Thus, the system is deadlocked,
+and there can be no forward progress; the OS thinks there's nothing
+to do, and the hardware has nowhere to put incoming data.
+
+This bug/feature is worked around with the spider_net_resync_head_ptr()
+routine. When the driver receives RX interrupts, but an examination
+of the RX chain seems to show it is empty, then it is probable that
+the hardware has skipped a descr or two (sometimes dozens under heavy
+network conditions). The spider_net_resync_head_ptr() subroutine will
+search the ring for the next full descr, and the driver will resume
+operations there.  Since this will leave "holes" in the ring, there
+is also a spider_net_resync_tail_ptr() that will skip over such holes.
+
+As of this writing, the spider_net_resync() strategy seems to work very
+well, even under heavy network loads.
+
+
+The TX ring
+===========
+The TX ring uses a low-watermark interrupt scheme to make sure that
+the TX queue is appropriately serviced for large packet sizes.
+
+For packet sizes greater than about 1KBytes, the kernel can fill
+the TX ring quicker than the device can drain it. Once the ring
+is full, the netdev is stopped. When there is room in the ring,
+the netdev needs to be reawakened, so that more TX packets are placed
+in the ring. The hardware can empty the ring about four times per jiffy,
+so its not appropriate to wait for the poll routine to refill, since
+the poll routine runs only once per jiffy.  The low-watermark mechanism
+marks a descr about 1/4th of the way from the bottom of the queue, so
+that an interrupt is generated when the descr is processed. This
+interrupt wakes up the netdev, which can then refill the queue.
+For large packets, this mechanism generates a relatively small number
+of interrupts, about 1K/sec. For smaller packets, this will drop to zero
+interrupts, as the hardware can empty the queue faster than the kernel
+can fill it.

+Linux power supply class
+========================
+
+Synopsis
+~~~~~~~~
+Power supply class used to represent battery, UPS, AC or DC power supply
+properties to user-space.
+
+It defines core set of attributes, which should be applicable to (almost)
+every power supply out there. Attributes are available via sysfs and uevent
+interfaces.
+
+Each attribute has well defined meaning, up to unit of measure used. While
+the attributes provided are believed to be universally applicable to any
+power supply, specific monitoring hardware may not be able to provide them
+all, so any of them may be skipped.
+
+Power supply class is extensible, and allows to define drivers own attributes.
+The core attribute set is subject to the standard Linux evolution (i.e.
+if it will be found that some attribute is applicable to many power supply
+types or their drivers, it can be added to the core set).
+
+It also integrates with LED framework, for the purpose of providing
+typically expected feedback of battery charging/fully charged status and
+AC/USB power supply online status. (Note that specific details of the
+indication (including whether to use it at all) are fully controllable by
+user and/or specific machine defaults, per design principles of LED
+framework).
+
+
+Attributes/properties
+~~~~~~~~~~~~~~~~~~~~~
+Power supply class has predefined set of attributes, this eliminates code
+duplication across drivers. Power supply class insist on reusing its
+predefined attributes *and* their units.
+
+So, userspace gets predictable set of attributes and their units for any
+kind of power supply, and can process/present them to a user in consistent
+manner. Results for different power supplies and machines are also directly
+comparable.
+
+See drivers/power/ds2760_battery.c and drivers/power/pda_power.c for the
+example how to declare and handle attributes.
+
+
+Units
+~~~~~
+Quoting include/linux/power_supply.h:
+
+  All voltages, currents, charges, energies, time and temperatures in µV,
+  µA, µAh, µWh, seconds and tenths of degree Celsius unless otherwise
+  stated. It's driver's job to convert its raw values to units in which
+  this class operates.
+
+

+~                                                                       ~
+~ Because both "charge" (µAh) and "energy" (µWh) represents "capacity"  ~
+~ of battery, this class distinguish these terms. Don't mix them!       ~
+~                                                                       ~

+
+Postfixes:
+_AVG - *hardware* averaged value, use it if your hardware is really able to
+report averaged values.
+_NOW - momentary/instantaneous values.
+
+STATUS - this attribute represents operating status (charging, full,
+discharging (i.e. powering a load), etc.). This corresponds to
+BATTERY_STATUS_* values, as defined in battery.h.
+
+HEALTH - represents health of the battery, values corresponds to
+POWER_SUPPLY_HEALTH_*, defined in battery.h.
+
+VOLTAGE_MAX_DESIGN, VOLTAGE_MIN_DESIGN - design values for maximal and
+minimal power supply voltages. Maximal/minimal means values of voltages
+when battery considered "full"/"empty" at normal conditions. Yes, there is
+no direct relation between voltage and battery capacity, but some dumb
+batteries use voltage for very approximated calculation of capacity.
+Battery driver also can use this attribute just to inform userspace
+about maximal and minimal voltage thresholds of a given battery.
+
+CHARGE_FULL_DESIGN, CHARGE_EMPTY_DESIGN - design charge values, when
+battery considered full/empty.
+
+ENERGY_FULL_DESIGN, ENERGY_EMPTY_DESIGN - same as above but for energy.
+
+CHARGE_FULL, CHARGE_EMPTY - These attributes means "last remembered value
+of charge when battery became full/empty". It also could mean "value of
+charge when battery considered full/empty at given conditions (temperature,
+age)". I.e. these attributes represents real thresholds, not design values.
+
+ENERGY_FULL, ENERGY_EMPTY - same as above but for energy.
+
+CAPACITY - capacity in percents.
+CAPACITY_LEVEL - capacity level. This corresponds to
+POWER_SUPPLY_CAPACITY_LEVEL_*.
+
+TEMP - temperature of the power supply.
+TEMP_AMBIENT - ambient temperature.
+
+TIME_TO_EMPTY - seconds left for battery to be considered empty (i.e.
+while battery powers a load)
+TIME_TO_FULL - seconds left for battery to be considered full (i.e.
+while battery is charging)
+
+
+Battery <-> external power supply interaction
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Often power supplies are acting as supplies and supplicants at the same
+time. Batteries are good example. So, batteries usually care if they're
+externally powered or not.
+
+For that case, power supply class implements notification mechanism for
+batteries.
+
+External power supply (AC) lists supplicants (batteries) names in
+"supplied_to" struct member, and each power_supply_changed() call
+issued by external power supply will notify supplicants via
+external_power_changed callback.
+
+
+QA
+~~
+Q: Where is POWER_SUPPLY_PROP_XYZ attribute?
+A: If you cannot find attribute suitable for your driver needs, feel free
+   to add it and send patch along with your driver.
+
+   The attributes available currently are the ones currently provided by the
+   drivers written.
+
+   Good candidates to add in future: model/part#, cycle_time, manufacturer,
+   etc.
+
+
+Q: I have some very specific attribute (e.g. battery color), should I add
+   this attribute to standard ones?
+A: Most likely, no. Such attribute can be placed in the driver itself, if
+   it is useful. Of course, if the attribute in question applicable to
+   large set of batteries, provided by many drivers, and/or comes from
+   some general battery specification/standard, it may be a candidate to
+   be added to the core attribute set.
+
+
+Q: Suppose, my battery monitoring chip/firmware does not provides capacity
+   in percents, but provides charge_{now,full,empty}. Should I calculate
+   percentage capacity manually, inside the driver, and register CAPACITY
+   attribute? The same question about time_to_empty/time_to_full.
+A: Most likely, no. This class is designed to export properties which are
+   directly measurable by the specific hardware available.
+
+   Inferring not available properties using some heuristics or mathematical
+   model is not subject of work for a battery driver. Such functionality
+   should be factored out, and in fact, apm_power, the driver to serve
+   legacy APM API on top of power supply class, uses a simple heuristic of
+   approximating remaining battery capacity based on its charge, current,
+   voltage and so on. But full-fledged battery model is likely not subject
+   for kernel at all, as it would require floating point calculation to deal
+   with things like differential equations and Kalman filters. This is
+   better be handled by batteryd/libbattery, yet to be written.

+This is the CFS scheduler.
+
+80% of CFS's design can be summed up in a single sentence: CFS basically
+models an "ideal, precise multi-tasking CPU" on real hardware.
+
+"Ideal multi-tasking CPU" is a (non-existent  :-))  CPU that has 100%
+physical power and which can run each task at precise equal speed, in
+parallel, each at 1/nr_running speed. For example: if there are 2 tasks
+running then it runs each at 50% physical power - totally in parallel.

+On real hardware, we can run only a single task at once, so while that
+one task runs, the other tasks that are waiting for the CPU are at a
+disadvantage - the current task gets an unfair amount of CPU time. In
+CFS this fairness imbalance is expressed and tracked via the per-task
+p->wait_runtime (nanosec-unit) value. "wait_runtime" is the amount of
+time the task should now run on the CPU for it to become completely fair
+and balanced.
+
+( small detail: on 'ideal' hardware, the p->wait_runtime value would
+  always be zero - no task would ever get 'out of balance' from the
+  'ideal' share of CPU time. )
+
+CFS's task picking logic is based on this p->wait_runtime value and it
+is thus very simple: it always tries to run the task with the largest
+p->wait_runtime value. In other words, CFS tries to run the task with
+the 'gravest need' for more CPU time. So CFS always tries to split up
+CPU time between runnable tasks as close to 'ideal multitasking
+hardware' as possible.
+
+Most of the rest of CFS's design just falls out of this really simple
+concept, with a few add-on embellishments like nice levels,
+multiprocessing and various algorithm variants to recognize sleepers.
+
+In practice it works like this: the system runs a task a bit, and when
+the task schedules (or a scheduler tick happens) the task's CPU usage is
+'accounted for': the (small) time it just spent using the physical CPU
+is deducted from p->wait_runtime. [minus the 'fair share' it would have
+gotten anyway]. Once p->wait_runtime gets low enough so that another
+task becomes the 'leftmost task' of the time-ordered rbtree it maintains
+(plus a small amount of 'granularity' distance relative to the leftmost
+task so that we do not over-schedule tasks and trash the cache) then the
+new leftmost task is picked and the current task is preempted.
+
+The rq->fair_clock value tracks the 'CPU time a runnable task would have
+fairly gotten, had it been runnable during that time'. So by using
+rq->fair_clock values we can accurately timestamp and measure the
+'expected CPU time' a task should have gotten. All runnable tasks are
+sorted in the rbtree by the "rq->fair_clock - p->wait_runtime" key, and
+CFS picks the 'leftmost' task and sticks to it. As the system progresses
+forwards, newly woken tasks are put into the tree more and more to the
+right - slowly but surely giving a chance for every task to become the
+'leftmost task' and thus get on the CPU within a deterministic amount of
+time.
+
+Some implementation details:
+
+ - the introduction of Scheduling Classes: an extensible hierarchy of
+   scheduler modules. These modules encapsulate scheduling policy
+   details and are handled by the scheduler core without the core
+   code assuming about them too much.
+
+ - sched_fair.c implements the 'CFS desktop scheduler': it is a
+   replacement for the vanilla scheduler's SCHED_OTHER interactivity
+   code.
+
+   I'd like to give credit to Con Kolivas for the general approach here:
+   he has proven via RSDL/SD that 'fair scheduling' is possible and that
+   it results in better desktop scheduling. Kudos Con!
+
+   The CFS patch uses a completely different approach and implementation
+   from RSDL/SD. My goal was to make CFS's interactivity quality exceed
+   that of RSDL/SD, which is a high standard to meet :-) Testing
+   feedback is welcome to decide this one way or another. [ and, in any
+   case, all of SD's logic could be added via a kernel/sched_sd.c module
+   as well, if Con is interested in such an approach. ]
+
+   CFS's design is quite radical: it does not use runqueues, it uses a
+   time-ordered rbtree to build a 'timeline' of future task execution,
+   and thus has no 'array switch' artifacts (by which both the vanilla
+   scheduler and RSDL/SD are affected).
+
+   CFS uses nanosecond granularity accounting and does not rely on any
+   jiffies or other HZ detail. Thus the CFS scheduler has no notion of
+   'timeslices' and has no heuristics whatsoever. There is only one
+   central tunable:
+
+         /proc/sys/kernel/sched_granularity_ns
+
+   which can be used to tune the scheduler from 'desktop' (low
+   latencies) to 'server' (good batching) workloads. It defaults to a
+   setting suitable for desktop workloads. SCHED_BATCH is handled by the
+   CFS scheduler module too.
+
+   Due to its design, the CFS scheduler is not prone to any of the
+   'attacks' that exist today against the heuristics of the stock
+   scheduler: fiftyp.c, thud.c, chew.c, ring-test.c, massive_intr.c all
+   work fine and do not impact interactivity and produce the expected
+   behavior.
+
+   the CFS scheduler has a much stronger handling of nice levels and
+   SCHED_BATCH: both types of workloads should be isolated much more
+   agressively than under the vanilla scheduler.
+
+   ( another detail: due to nanosec accounting and timeline sorting,
+     sched_yield() support is very simple under CFS, and in fact under
+     CFS sched_yield() behaves much better than under any other
+     scheduler i have tested so far. )
+
+ - sched_rt.c implements SCHED_FIFO and SCHED_RR semantics, in a simpler
+   way than the vanilla scheduler does. It uses 100 runqueues (for all
+   100 RT priority levels, instead of 140 in the vanilla scheduler)
+   and it needs no expired array.
+
+ - reworked/sanitized SMP load-balancing: the runqueue-walking
+   assumptions are gone from the load-balancing code now, and
+   iterators of the scheduling modules are used. The balancing code got
+   quite a bit simpler as a result.

- *    the interrupt service routine while interrupts are disabled.
- *    Maybe a timer interrupt will get lost :-(
- */
-
-/*
- * General notes:
- *
- *  - All ACSI devices (disks, CD-ROMs, ...) use major number 28.
- *    Minors are organized like it is with SCSI: The upper 4 bits
- *    identify the device, the lower 4 bits the partition.
- *    The device numbers (the upper 4 bits) are given in the same
- *    order as the devices are found on the bus.
- *  - Up to 8 LUNs are supported for each target (if CONFIG_ACSI_MULTI_LUN
- *    is defined), but only a total of 16 devices (due to minor
- *    numbers...). Note that Atari allows only a maximum of 4 targets
- *    (i.e. controllers, not devices) on the ACSI bus!
- *  - A optimizing scheme similar to SCSI scatter-gather is implemented.
- *  - Removable media are supported. After a medium change to device
- *    is reinitialized (partition check etc.). Also, if the device
- *    knows the PREVENT/ALLOW MEDIUM REMOVAL command, the door should
- *    be locked and unlocked when mounting the first or unmounting the
- *    last filesystem on the device. The code is untested, because I
- *    don't have a removable hard disk.

-	  <http://www.tldp.org/docs.html#howto>.
-
-	  Note that the answer to this question doesn't directly affect the

-	  the questions about these CD-ROM drives. If you are unsure what you
-	  have, say Y and find out whether you have one of the following
-	  drives.
-
-	  For each of these drivers, a <file:Documentation/cdrom/{driver_name}>
-	  exists. Especially in cases where you do not know exactly which kind
-	  of drive you have you should read there. Most of these drivers use a
-	  file drivers/cdrom/{driver_name}.h where you can define your
-	  interface parameters and switch some internal goodies.
-
-	  To compile these CD-ROM drivers as a module, choose M instead of Y.
-
-	  If you want to use any of these CD-ROM drivers, you also have to

-	  "electrically compatible" drives (Vertos, Genoa, some Funai models)
-	  are currently not supported; for the Sanyo H94A drive currently a
-	  separate driver (asked later) is responsible.  Most drives have a
-	  uniquely shaped faceplate, with a caddyless motorized drawer, but
-	  without external brand markings.  The older CR-52x drives have a
-	  caddy and manual loading/eject, but still no external markings.  The
-	  driver is able to do an extended auto-probing for interface
-	  addresses and drive types; this can help to find facts in cases you
-	  are not sure, but can consume some time during the boot process if

-	HISTORY
-	V0.0    Adaption to Aztech CD268-01A Version 1.3
-		Version is PRE_ALPHA, unresolved points:
-		1. I use busy wait instead of timer wait in STEN_LOW,DTEN_LOW
-		   thus driver causes CPU overhead and is very slow 
-		2. could not find a way to stop the drive, when it is
-		   in data read mode, therefore I had to set
-		   msf.end.min/sec/frame to 0:0:1 (in azt_poll); so only one
-		   frame can be read in sequence, this is also the reason for
-		3. getting 'timeout in state 4' messages, but nevertheless
-		   it works
-		W.Zimmermann, Oct. 31, 1994
-	V0.1    Version is ALPHA, problems #2 and #3 resolved.  
-		W.Zimmermann, Nov. 3, 1994
-	V0.2    Modification to some comments, debugging aids for partial test
-		with Borland C under DOS eliminated. Timer interrupt wait 
-		STEN_LOW_WAIT additionally to busy wait for STEN_LOW implemented; 
-		use it only for the 'slow' commands (ACMD_GET_Q_CHANNEL, ACMD_
-		SEEK_TO_LEAD_IN), all other commands are so 'fast', that busy 
-		waiting seems better to me than interrupt rescheduling.
-		Besides that, when used in the wrong place, STEN_LOW_WAIT causes
-		kernel panic.
-		In function aztPlay command ACMD_PLAY_AUDIO added, should make
-		audio functions work. The Aztech drive needs different commands
-		to read data tracks and play audio tracks.
-		W.Zimmermann, Nov. 8, 1994
-	V0.3    Recognition of missing drive during boot up improved (speeded up).
-		W.Zimmermann, Nov. 13, 1994
-	V0.35   Rewrote the control mechanism in azt_poll (formerly mcd_poll) 
-		including removal of all 'goto' commands. :-); 
-		J. Nardone, Nov. 14, 1994
-	V0.4    Renamed variables and constants to 'azt' instead of 'mcd'; had
-		to make some "compatibility" defines in azt.h; please note,
-		that the source file was renamed to azt.c, the include file to
-		azt.h                
-		Speeded up drive recognition during init (will be a little bit 
-		slower than before if no drive is installed!); suggested by
-		Robby Schirmer.
-		read_count declared volatile and set to AZT_BUF_SIZ to make
-		drive faster (now 300kB/sec, was 60kB/sec before, measured
-		by 'time dd if=/dev/cdrom of=/dev/null bs=2048 count=4096';
-		different AZT_BUF_SIZes were test, above 16 no further im-
-		provement seems to be possible; suggested by E.Moenkeberg.
-		W.Zimmermann, Nov. 18, 1994
-	V0.42   Included getAztStatus command in GetQChannelInfo() to allow
-		reading Q-channel info on audio disks, if drive is stopped, 
-		and some other bug fixes in the audio stuff, suggested by 
-		Robby Schirmer.
-		Added more ioctls (reading data in mode 1 and mode 2).
-		Completely removed the old azt_poll() routine.
-		Detection of ORCHID CDS-3110 in aztcd_init implemented.
-		Additional debugging aids (see the readme file).
-		W.Zimmermann, Dec. 9, 1994  
-	V0.50   Autodetection of drives implemented.
-		W.Zimmermann, Dec. 12, 1994
-	V0.52   Prepared for including in the standard kernel, renamed most
-		variables to contain 'azt', included autoconf.h
-		W.Zimmermann, Dec. 16, 1994        
-	V0.6    Version for being included in the standard Linux kernel.
-		Renamed source and header file to aztcd.c and aztcd.h
-		W.Zimmermann, Dec. 24, 1994
-	V0.7    Changed VERIFY_READ to VERIFY_WRITE in aztcd_ioctl, case
-		CDROMREADMODE1 and CDROMREADMODE2; bug fix in the ioctl,
-		which causes kernel crashes when playing audio, changed 
-		include-files (config.h instead of autoconf.h, removed
-		delay.h)
-		W.Zimmermann, Jan. 8, 1995
-	V0.72   Some more modifications for adaption to the standard kernel.
-		W.Zimmermann, Jan. 16, 1995
-        V0.80   aztcd is now part of the standard kernel since version 1.1.83.
-                Modified the SET_TIMER and CLEAR_TIMER macros to comply with
-                the new timer scheme.
-                W.Zimmermann, Jan. 21, 1995
-        V0.90   Included CDROMVOLCTRL, but with my Aztech drive I can only turn
-                the channels on and off. If it works better with your drive, 
-                please mail me. Also implemented ACMD_CLOSE for CDROMSTART.
-                W.Zimmermann, Jan. 24, 1995
-        V1.00   Implemented close and lock tray commands. Patches supplied by
-		Frank Racis        
-                Added support for loadable MODULEs, so aztcd can now also be
-                loaded by insmod and removed by rmmod during run time
-                Werner Zimmermann, Mar. 24, 95
-        V1.10   Implemented soundcard configuration for Orchid CDS-3110 drives
-                connected to Soundwave32 cards. Release for LST 2.1.
-                (still experimental)
-                Werner Zimmermann, May 8, 95
-        V1.20   Implemented limited support for DOSEMU0.60's cdrom.c. Now it works, but
-                sometimes DOSEMU may hang for 30 seconds or so. A fully functional ver-
-                sion needs an update of Dosemu0.60's cdrom.c, which will come with the 
-                next revision of Dosemu.
-                Also Soundwave32 support now works.
-                Werner Zimmermann, May 22, 95
-	V1.30   Auto-eject feature. Inspired by Franc Racis (racis@psu.edu)
-	        Werner Zimmermann, July 4, 95
-	V1.40   Started multisession support. Implementation copied from mcdx.c
-	        by Heiko Schlittermann. Not tested yet.
-	        Werner Zimmermann, July 15, 95
-        V1.50   Implementation of ioctl CDROMRESET, continued multisession, began
-                XA, but still untested. Heavy modifications to drive status de-
-                tection.
-                Werner Zimmermann, July 25, 95
-        V1.60   XA support now should work. Speeded up drive recognition in cases, 
-                where no drive is installed.
-                Werner Zimmermann, August 8, 1995
-        V1.70   Multisession support now is completed, but there is still not 
-                enough testing done. If you can test it, please contact me. For
-                details please read Documentation/cdrom/aztcd
-                Werner Zimmermann, August 19, 1995
-        V1.80   Modification to suit the new kernel boot procedure introduced
-                with kernel 1.3.33. Will definitely not work with older kernels.
-                Programming done by Linus himself.
-                Werner Zimmermann, October 11, 1995
-	V1.90   Support for Conrad TXC drives, thank's to Jochen Kunz and Olaf Kaluza.
-	        Werner Zimmermann, October 21, 1995
-        V2.00   Changed #include "blk.h" to <linux/blk.h> as the directory
-                structure was changed. README.aztcd is now /usr/src/docu-
-                mentation/cdrom/aztcd
-                Werner Zimmermann, November 10, 95
-        V2.10   Started to modify azt_poll to prevent reading beyond end of
-                tracks.
-                Werner Zimmermann, December 3, 95
-        V2.20   Changed some comments
-                Werner Zimmermann, April 1, 96
-        V2.30   Implemented support for CyCDROM CR520, CR940, Code for CR520 
-        	delivered by H.Berger with preworks by E.Moenkeberg.
-                Werner Zimmermann, April 29, 96
-        V2.40   Reorganized the placement of functions in the source code file
-                to reflect the layered approach; did not actually change code
-                Werner Zimmermann, May 1, 96
-        V2.50   Heiko Eissfeldt suggested to remove some VERIFY_READs in 
-                aztcd_ioctl; check_aztcd_media_change modified 
-                Werner Zimmermann, May 16, 96       
-	V2.60   Implemented Auto-Probing; made changes for kernel's 2.1.xx blocksize
-                Adaption to linux kernel > 2.1.0
-		Werner Zimmermann, Nov 29, 97
-		
-        November 1999 -- Make kernel-parameter implementation work with 2.3.x 
-	                 Removed init_module & cleanup_module in favor of 
-			 module_init & module_exit.

-* Sony CDU-31A CDROM interface device driver.
-*
-* Corey Minyard (minyard@wf-rch.cirr.com)
-*
-* Colossians 3:17
-*
-*  See Documentation/cdrom/cdu31a for additional details about this driver.
-* 
-* The Sony interface device driver handles Sony interface CDROM
-* drives and provides a complete block-level interface as well as an
-* ioctl() interface compatible with the Sun (as specified in
-* include/linux/cdrom.h).  With this interface, CDROMs can be
-* accessed and standard audio CDs can be played back normally.
-*
-* WARNING - 	All autoprobes have been removed from the driver.
-*		You MUST configure the CDU31A via a LILO config
-*		at boot time or in lilo.conf.  I have the
-*		following in my lilo.conf:
-*
-*                append="cdu31a=0x1f88,0,PAS"
-*
-*		The first number is the I/O base address of the
-*		card.  The second is the interrupt (0 means none).
- *		The third should be "PAS" if on a Pro-Audio
- *		spectrum, or nothing if on something else.
- *
- * This interface is (unfortunately) a polled interface.  This is
- * because most Sony interfaces are set up with DMA and interrupts
- * disables.  Some (like mine) do not even have the capability to
- * handle interrupts or DMA.  For this reason you will see a lot of
- * the following:
- *
- *   retry_count = jiffies+ SONY_JIFFIES_TIMEOUT;
- *   while (time_before(jiffies, retry_count) && (! <some condition to wait for))
- *   {
- *      while (handle_sony_cd_attention())
- *         ;
- *
- *      sony_sleep();
- *   }
- *   if (the condition not met)
- *   {
- *      return an error;
- *   }
- *
- * This ugly hack waits for something to happen, sleeping a little
- * between every try.  it also handles attentions, which are
- * asynchronous events from the drive informing the driver that a disk
- * has been inserted, removed, etc.
- *
- * NEWS FLASH - The driver now supports interrupts but they are
- * turned off by default.  Use of interrupts is highly encouraged, it
- * cuts CPU usage down to a reasonable level.  I had DMA in for a while
- * but PC DMA is just too slow.  Better to just insb() it.
- *
- * One thing about these drives: They talk in MSF (Minute Second Frame) format.
- * There are 75 frames a second, 60 seconds a minute, and up to 75 minutes on a
- * disk.  The funny thing is that these are sent to the drive in BCD, but the
- * interface wants to see them in decimal.  A lot of conversion goes on.
- *
- * DRIVER SPECIAL FEATURES
- * -----------------------
- *
- * This section describes features beyond the normal audio and CD-ROM
- * functions of the drive.
- *
- * XA compatibility
- *
- * The driver should support XA disks for both the CDU31A and CDU33A.
- * It does this transparently, the using program doesn't need to set it.
- *
- * Multi-Session
- *
- * A multi-session disk looks just like a normal disk to the user.
- * Just mount one normally, and all the data should be there.
- * A special thanks to Koen for help with this!
- * 
- * Raw sector I/O
- *
- * Using the CDROMREADAUDIO it is possible to read raw audio and data
- * tracks.  Both operations return 2352 bytes per sector.  On the data
- * tracks, the first 12 bytes is not returned by the drive and the value
- * of that data is indeterminate.

- * Credits:
- *    Heiko Eissfeldt <heiko@colossus.escape.de>
- *         For finding abug in the return of the track numbers.
- *         TOC processing redone for proper multisession support.
- *
- *
- *  It probably a little late to be adding a history, but I guess I
- *  will start.
- *
- *  10/24/95 - Added support for disabling the eject button when the
- *             drive is open.  Note that there is a small problem
- *             still here, if the eject button is pushed while the
- *             drive light is flashing, the drive will return a bad
- *             status and be reset.  It recovers, though.
- *
- *  03/07/97 - Fixed a problem with timers.
- *
- *
- *  18 Spetember 1997 -- Ported to Uniform CD-ROM driver by 
- *                 Heiko Eissfeldt <heiko@colossus.escape.de> with additional
- *                 changes by Erik Andersen <andersee@debian.org>
- *
- *  24 January 1998 -- Removed the scd_disc_status() function, which was now
- *                     just dead code left over from the port.
- *                          Erik Andersen <andersee@debian.org>
- *
- *  16 July 1998 -- Drive donated to Erik Andersen by John Kodis
- *                   <kodis@jagunet.com>.  Work begun on fixing driver to
- *                   work under 2.1.X.  Added temporary extra printks
- *                   which seem to slow it down enough to work.
- *
- *  9 November 1999 -- Make kernel-parameter implementation work with 2.3.x 
- *	               Removed init_module & cleanup_module in favor of 
- *		       module_init & module_exit.
- *		       Torben Mathiasen <tmm@image.dk>
- *
- * 22 October 2004 -- Make the driver work in 2.6.X
- *		      Added workaround to fix hard lockups on eject
- *		      Fixed door locking problem after mounting empty drive
- *		      Set double-speed drives to double speed by default
- *		      Removed all readahead things - not needed anymore

-History:
- Started 25 jan 1994. Waiting for documentation...
- 22 feb 1995: 0.1a first reasonably safe polling driver.
-	      Two major bugs, one in read_sector and one in 
-	      do_cm206_request, happened to cancel!
- 25 feb 1995: 0.2a first reasonable interrupt driven version of above.
-              uart writes are still done in polling mode. 
- 25 feb 1995: 0.21a writes also in interrupt mode, still some
-	      small bugs to be found... Larger buffer. 
-  2 mrt 1995: 0.22 Bug found (cd-> nowhere, interrupt was called in
-              initialization), read_ahead of 16. Timeouts implemented.
-	      unclear if they do something...
-  7 mrt 1995: 0.23 Start of background read-ahead.
- 18 mrt 1995: 0.24 Working background read-ahead. (still problems)
- 26 mrt 1995: 0.25 Multi-session ioctl added (kernel v1.2).
-              Statistics implemented, though separate stats206.h.
-	      Accessible through ioctl 0x1000 (just a number).
-	      Hard to choose between v1.2 development and 1.1.75.
-	      Bottom-half doesn't work with 1.2...
-	      0.25a: fixed... typo. Still problems...
-  1 apr 1995: 0.26 Module support added. Most bugs found. Use kernel 1.2.n.
-  5 apr 1995: 0.27 Auto-probe for the adapter card base address.
-              Auto-probe for the adaptor card irq line.
-  7 apr 1995: 0.28 Added lilo setup support for base address and irq.
-              Use major number 32 (not in this source), officially
-	      assigned to this driver.
-  9 apr 1995: 0.29 Added very limited audio support. Toc_header, stop, pause,
-              resume, eject. Play_track ignores track info, because we can't 
-	      read a table-of-contents entry. Toc_entry is implemented
-	      as a `placebo' function: always returns start of disc. 
-  3 may 1995: 0.30 Audio support completed. The get_toc_entry function
-              is implemented as a binary search. 
- 15 may 1995: 0.31 More work on audio stuff. Workman is not easy to 
-              satisfy; changed binary search into linear search.
-	      Auto-probe for base address somewhat relaxed.
-  1 jun 1995: 0.32 Removed probe_irq_on/off for module version.
- 10 jun 1995: 0.33 Workman still behaves funny, but you should be
-              able to eject and substitute another disc.
-
- An adaptation of 0.33 is included in linux-1.3.7 by Eberhard Moenkeberg
-
- 18 jul 1995: 0.34 Patch by Heiko Eissfeldt included, mainly considering 
-              verify_area's in the ioctls. Some bugs introduced by 
-	      EM considering the base port and irq fixed. 
-
- 18 dec 1995: 0.35 Add some code for error checking... no luck...
-
- We jump to reach our goal: version 1.0 in the next stable linux kernel.
-
- 19 mar 1996: 0.95 Different implementation of CDROM_GET_UPC, on
-	      request of Thomas Quinot. 
- 25 mar 1996: 0.96 Interpretation of opening with O_WRONLY or O_RDWR:
-	      open only for ioctl operation, e.g., for operation of
-	      tray etc.
- 4 apr 1996:  0.97 First implementation of layer between VFS and cdrom
-              driver, a generic interface. Much of the functionality
-	      of cm206_open() and cm206_ioctl() is transferred to a
-	      new file cdrom.c and its header ucdrom.h. 
-
-	      Upgrade to Linux kernel 1.3.78. 
-
- 11 apr 1996  0.98 Upgrade to Linux kernel 1.3.85
-              More code moved to cdrom.c
- 
- 	      0.99 Some more small changes to decrease number
- 	      of oopses at module load; 
- 
- 27 jul 1996  0.100 Many hours of debugging, kernel change from 1.2.13
-	      to 2.0.7 seems to have introduced some weird behavior
-	      in (interruptible_)sleep_on(&cd->data): the process
-	      seems to be woken without any explicit wake_up in my own
-	      code. Patch to try 100x in case such untriggered wake_up's 
-	      occur. 
-
- 28 jul 1996  0.101 Rewriting of the code that receives the command echo,
-	      using a fifo to store echoed bytes. 
-
- 	      Branch from 0.99:
- 
- 	      0.99.1.0 Update to kernel release 2.0.10 dev_t -> kdev_t
- 	      (emoenke) various typos found by others.  extra
- 	      module-load oops protection.
- 
- 	      0.99.1.1 Initialization constant cdrom_dops.speed
- 	      changed from float (2.0) to int (2); Cli()-sti() pair
- 	      around cm260_reset() in module initialization code.
- 
- 	      0.99.1.2 Changes literally as proposed by Scott Snyder
- 	      <snyder@d0sgif.fnal.gov> for the 2.1 kernel line, which
- 	      have to do mainly with the poor minor support i had. The
- 	      major new concept is to change a cdrom driver's
- 	      operations struct from the capabilities struct. This
- 	      reflects the fact that there is one major for a driver,
- 	      whilst there can be many minors whith completely
- 	      different capabilities.
-
-	      0.99.1.3 More changes for operations/info separation.
-
-	      0.99.1.4 Added speed selection (someone had to do this
-	      first).
-
-  23 jan 1997 0.99.1.5 MODULE_PARMS call added.
-
-  23 jan 1997 0.100.1.2--0.100.1.5 following similar lines as 
-  	      0.99.1.1--0.99.1.5. I get too many complaints about the
-	      drive making read errors. What't wrong with the 2.0+
-	      kernel line? Why get i (and othe cm206 owners) weird
-	      results? Why were things good in the good old 1.1--1.2 
-	      era? Why don't i throw away the drive?
-
- 2 feb 1997   0.102 Added `volatile' to values in cm206_struct. Seems to 
- 	      reduce many of the problems. Rewrote polling routines
-	      to use fixed delays between polls. 
-	      0.103 Changed printk behavior. 
-	      0.104 Added a 0.100 -> 0.100.1.1 change
-
-11 feb 1997   0.105 Allow auto_probe during module load, disable
-              with module option "auto_probe=0". Moved some debugging
-	      statements to lower priority. Implemented select_speed()
-	      function. 
-
-13 feb 1997   1.0 Final version for 2.0 kernel line. 
-
-	      All following changes will be for the 2.1 kernel line. 
-
-15 feb 1997   1.1 Keep up with kernel 2.1.26, merge in changes from 
-              cdrom.c 0.100.1.1--1.0. Add some more MODULE_PARMS. 
-
-14 sep 1997   1.2 Upgrade to Linux 2.1.55.  Added blksize_size[], patch
-              sent by James Bottomley <James.Bottomley@columbiasc.ncr.com>.
-
-21 dec 1997   1.4 Upgrade to Linux 2.1.72.  
-
-24 jan 1998   Removed the cm206_disc_status() function, as it was now dead
-              code.  The Uniform CDROM driver now provides this functionality.
-	      
-9 Nov. 1999   Make kernel-parameter implementation work with 2.3.x 
-	      Removed init_module & cleanup_module in favor of 
-	      module_init & module_exit.
-	      Torben Mathiasen <tmm@image.dk>
- * 
- * Parts of the code are based upon lmscd.c written by Kai Petzke,
- * sbpcd.c written by Eberhard Moenkeberg, and mcd.c by Martin
- * Harriss, but any off-the-shelf dynamic programming algorithm won't
- * be able to find them.
- *
- * The cm206 drive interface and the cm260 adapter card seem to be 
- * sufficiently different from their cm205/cm250 counterparts
- * in order to write a complete new driver.
- * 
- * I call all routines connected to the Linux kernel something
- * with `cm206' in it, as this stuff is too series-dependent. 
- * 
- * Currently, my limited knowledge is based on:
- * - The Linux Kernel Hacker's guide, v. 0.5, by Michael K. Johnson
- * - Linux Kernel Programmierung, by Michael Beck and others
- * - Philips/LMS cm206 and cm226 product specification
- * - Philips/LMS cm260 product specification

-/*	Revision history
-
-
-	14-5-95		v0.0	Plays sound tracks. No reading of data CDs yet.
-				Detection of disk change doesn't work.
-	21-5-95		v0.1	First ALPHA version. CD can be mounted. The
-				device major nr is borrowed from the Aztech
-				driver. Speed is around 240 kb/s, as measured
-				with "time dd if=/dev/cdrom of=/dev/null \
-				bs=2048 count=4096".
-	24-6-95		v0.2	Reworked the #defines for the command codes
-				and the like, as well as the structure of
-				the hardware communication protocol, to
-				reflect the "official" documentation, kindly
-				supplied by C.K. Tan, Optics Storage Pte. Ltd.
-				Also tidied up the state machine somewhat.
-	28-6-95		v0.3	Removed the ISP-16 interface code, as this
-				should go into its own driver. The driver now
-				has its own major nr.
-				Disk change detection now seems to work, too.
-				This version became part of the standard
-				kernel as of version 1.3.7
-	24-9-95		v0.4	Re-inserted ISP-16 interface code which I
-				copied from sjcd.c, with a few changes.
-				Updated README.optcd. Submitted for
-				inclusion in 1.3.21
-	29-9-95		v0.4a	Fixed bug that prevented compilation as module
-	25-10-95	v0.5	Started multisession code. Implementation
-				copied from Werner Zimmermann, who copied it
-				from Heiko Schlittermann's mcdx.
-	17-1-96		v0.6	Multisession works; some cleanup too.
-	18-4-96		v0.7	Increased some timing constants;
-				thanks to Luke McFarlane. Also tidied up some
-				printk behaviour. ISP16 initialization
-				is now handled by a separate driver.
-				
-	09-11-99 	  	Make kernel-parameter implementation work with 2.3.x 
-	                 	Removed init_module & cleanup_module in favor of 
-			 	module_init & module_exit.

- *  VERSION HISTORY
- *
- *  0.1  initial release, April/May 93, after mcd.c (Martin Harriss)
- *
- *  0.2  thek "repeat:"-loop in do_sbpcd_request did not check for
- *       end-of-request_queue (resulting in kernel panic).
- *       Flow control seems stable, but throughput is not better.  
- *
- *  0.3  interrupt locking totally eliminated (maybe "inb" and "outb"
- *       are still locking) - 0.2 made keyboard-type-ahead losses.
- *       check_sbpcd_media_change added (to use by isofs/inode.c)
- *       - but it detects almost nothing.
- *
- *  0.4  use MAJOR 25 definitely.
- *       Almost total re-design to support double-speed drives and
- *       "naked" (no sound) interface cards ("LaserMate" interface type).
- *       Flow control should be exact now.
- *       Don't occupy the SbPro IRQ line (not needed either); will
- *       live together with Hannu Savolainen's sndkit now.
- *       Speeded up data transfer to 150 kB/sec, with help from Kai
- *       Makisara, the "provider" of the "mt" tape utility.
- *       Give "SpinUp" command if necessary.
- *       First steps to support up to 4 drives (but currently only one).
- *       Implemented audio capabilities - workman should work, xcdplayer
- *       gives some problems.
- *       This version is still consuming too much CPU time, and
- *       sleeping still has to be worked on.
- *       During "long" implied seeks, it seems possible that a 
- *       ReadStatus command gets ignored. That gives the message
- *       "ResponseStatus timed out" (happens about 6 times here during
- *       a "ls -alR" of the YGGDRASIL LGX-Beta CD). Such a case is
- *       handled without data error, but it should get done better.
- *
- *  0.5  Free CPU during waits (again with help from Kai Makisara).
- *       Made it work together with the LILO/kernel setup standard.
- *       Included auto-probing code, as suggested by YGGDRASIL.
- *       Formal redesign to add DDI debugging.
- *       There are still flaws in IOCTL (workman with double speed drive).
- *
- *  1.0  Added support for all drive IDs (0...3, no longer only 0)
- *       and up to 4 drives on one controller.
- *       Added "#define MANY_SESSION" for "old" multi session CDs.
- *
- *  1.1  Do SpinUp for new drives, too.
- *       Revised for clean compile under "old" kernels (0.99pl9).
- *
- *  1.2  Found the "workman with double-speed drive" bug: use the driver's
- *       audio_state, not what the drive is reporting with ReadSubQ.
- *
- *  1.3  Minor cleanups.
- *       Refinements regarding Workman.
- *
- *  1.4  Read XA disks (PhotoCDs) with "old" drives, too (but only the first
- *       session - no chance to fully access a "multi-session" CD).
- *       This currently still is too slow (50 kB/sec) - but possibly
- *       the old drives won't do it faster.
- *       Implemented "door (un)lock" for new drives (still does not work
- *       as wanted - no lock possible after an unlock).
- *       Added some debugging printout for the UPC/EAN code - but my drives 
- *       return only zeroes. Is there no UPC/EAN code written?
- *
- *  1.5  Laborate with UPC/EAN code (not better yet).
- *       Adapt to kernel 1.1.8 change (have to explicitly include
- *       <linux/string.h> now).
- *
- *  1.6  Trying to read audio frames as data. Impossible with the current
- *       drive firmware levels, as it seems. Awaiting any hint. ;-)
- *       Changed "door unlock": repeat it until success.
- *       Changed CDROMSTOP routine (stop somewhat "softer" so that Workman
- *       won't get confused).
- *       Added a third interface type: Sequoia S-1000, as used with the SPEA
- *       Media FX sound card. This interface (usable for Sony and Mitsumi 
- *       drives, too) needs a special configuration setup and behaves like a 
- *       LaserMate type after that. Still experimental - I do not have such
- *       an interface.
- *       Use the "variable BLOCK_SIZE" feature (2048). But it does only work
- *       if you give the mount option "block=2048".
- *       The media_check routine is currently disabled; now that it gets
- *       called as it should I fear it must get synchronized for not to
- *       disturb the normal driver's activity.
- *
- *  2.0  Version number bumped - two reasons:
- *       - reading audio tracks as data works now with CR-562 and CR-563. We
- *       currently do it by an IOCTL (yet has to get standardized), one frame
- *       at a time; that is pretty slow. But it works.
- *       - we are maintaining now up to 4 interfaces (each up to 4 drives):
- *       did it the easy way - a different MAJOR (25, 26, ...) and a different
- *       copy of the driver (sbpcd.c, sbpcd2.c, sbpcd3.c, sbpcd4.c - only
- *       distinguished by the value of SBPCD_ISSUE and the driver's name),
- *       and a common sbpcd.h file.
- *       Bettered the "ReadCapacity error" problem with old CR-52x drives (the
- *       drives sometimes need a manual "eject/insert" before work): just
- *       reset the drive and do again. Needs lots of resets here and sometimes
- *       that does not cure, so this can't be the solution.
- *
- *  2.1  Found bug with multisession CDs (accessing frame 16).
- *       "read audio" works now with address type CDROM_MSF, too.
- *       Bigger audio frame buffer: allows reading max. 4 frames at time; this
- *       gives a significant speedup, but reading more than one frame at once
- *       gives missing chunks at each single frame boundary.
- *
- *  2.2  Kernel interface cleanups: timers, init, setup, media check.
- *
- *  2.3  Let "door lock" and "eject" live together.
- *       Implemented "close tray" (done automatically during open).
- *
- *  2.4  Use different names for device registering.
- *
- *  2.5  Added "#if EJECT" code (default: enabled) to automatically eject
- *       the tray during last call to "sbpcd_release".
- *       Added "#if JUKEBOX" code (default: disabled) to automatically eject
- *       the tray during call to "sbpcd_open" if no disk is in.
- *       Turn on the CD volume of "compatible" sound cards, too; just define
- *       SOUND_BASE (in sbpcd.h) accordingly (default: disabled).
- *
- *  2.6  Nothing new.  
- *
- *  2.7  Added CDROMEJECT_SW ioctl to set the "EJECT" behavior on the fly:
- *       0 disables, 1 enables auto-ejecting. Useful to keep the tray in
- *       during shutdown.
- *
- *  2.8  Added first support (still BETA, I need feedback or a drive) for
- *       the Longshine LCS-7260 drives. They appear as double-speed drives
- *       using the "old" command scheme, extended by tray control and door
- *       lock functions.
- *       Found (and fixed preliminary) a flaw with some multisession CDs: we
- *       have to re-direct not only the accesses to frame 16 (the isofs
- *       routines drive it up to max. 100), but also those to the continuation
- *       (repetition) frames (as far as they exist - currently set fix as
- *       16..20).
- *       Changed default of the "JUKEBOX" define. If you use this default,
- *       your tray will eject if you try to mount without a disk in. Next
- *       mount command will insert the tray - so, just fill in a disk. ;-)
- *
- *  2.9  Fulfilled the Longshine LCS-7260 support; with great help and
- *       experiments by Serge Robyns.
- *       First attempts to support the TEAC CD-55A drives; but still not
- *       usable yet.
- *       Implemented the CDROMMULTISESSION ioctl; this is an attempt to handle
- *       multi session CDs more "transparent" (redirection handling has to be
- *       done within the isofs routines, and only for the special purpose of
- *       obtaining the "right" volume descriptor; accesses to the raw device
- *       should not get redirected).
- *
- *  3.0  Just a "normal" increment, with some provisions to do it better. ;-)
- *       Introduced "#define READ_AUDIO" to specify the maximum number of 
- *       audio frames to grab with one request. This defines a buffer size
- *       within kernel space; a value of 0 will reserve no such space and
- *       disable the CDROMREADAUDIO ioctl. A value of 75 enables the reading
- *       of a whole second with one command, but will use a buffer of more
- *       than 172 kB.
- *       Started CD200 support. Drive detection should work, but nothing
- *       more.
- *
- *  3.1  Working to support the CD200 and the Teac CD-55A drives.
- *       AT-BUS style device numbering no longer used: use SCSI style now.
- *       So, the first "found" device has MINOR 0, regardless of the
- *       jumpered drive ID. This implies modifications to the /dev/sbpcd*
- *       entries for some people, but will help the DAU (german TLA, english:
- *       "newbie", maybe ;-) to install his "first" system from a CD.
- *
- *  3.2  Still testing with CD200 and CD-55A drives.
- *
- *  3.3  Working with CD200 support.
- *
- *  3.4  Auto-probing stops if an address of 0 is seen (to be entered with
- *       the kernel command line).
- *       Made the driver "loadable". If used as a module, "audio copy" is
- *       disabled, and the internal read ahead data buffer has a reduced size
- *       of 4 kB; so, throughput may be reduced a little bit with slow CPUs.
- *
- *  3.5  Provisions to handle weird photoCDs which have an interrupted
- *       "formatting" immediately after the last frames of some files: simply
- *       never "read ahead" with MultiSession CDs. By this, CPU usage may be
- *       increased with those CDs, and there may be a loss in speed.
- *       Re-structured the messaging system.
- *       The "loadable" version no longer has a limited READ_AUDIO buffer
- *       size.
- *       Removed "MANY_SESSION" handling for "old" multi session CDs.
- *       Added "private" IOCTLs CDROMRESET and CDROMVOLREAD.
- *       Started again to support the TEAC CD-55A drives, now that I found
- *       the money for "my own" drive. ;-)
- *       The TEAC CD-55A support is fairly working now.
- *       I have measured that the drive "delivers" at 600 kB/sec (even with
- *       bigger requests than the drive's 64 kB buffer can satisfy), but
- *       the "real" rate does not exceed 520 kB/sec at the moment. 
- *       Caused by the various changes to build in TEAC support, the timed
- *       loops are de-optimized at the moment (less throughput with CR-52x
- *       drives, and the TEAC will give speed only with SBP_BUFFER_FRAMES 64).
- *
- *  3.6  Fixed TEAC data read problems with SbPro interfaces.
- *       Initial size of the READ_AUDIO buffer is 0. Can get set to any size
- *       during runtime.
- *
- *  3.7  Introduced MAX_DRIVES for some poor interface cards (seen with TEAC
- *       drives) which allow only one drive (ID 0); this avoids repetitive
- *       detection under IDs 1..3. 
- *       Elongated cmd_out_T response waiting; necessary for photo CDs with
- *       a lot of sessions.
- *       Bettered the sbpcd_open() behavior with TEAC drives.
- *
- *  3.8  Elongated max_latency for CR-56x drives.
- *
- *  3.9  Finally fixed the long-known SoundScape/SPEA/Sequoia S-1000 interface
- *       configuration bug.
- *       Now Corey, Heiko, Ken, Leo, Vadim/Eric & Werner are invited to copy
- *       the config_spea() routine into their drivers. ;-)
- *
- *  4.0  No "big step" - normal version increment.
- *       Adapted the benefits from 1.3.33.
- *       Fiddled with CDROMREADAUDIO flaws.
- *       Avoid ReadCapacity command with CD200 drives (the MKE 1.01 version
- *       seems not to support it).
- *       Fulfilled "read audio" for CD200 drives, with help of Pete Heist
- *       (heistp@rpi.edu).
- *
- *  4.1  Use loglevel KERN_INFO with printk().
- *       Added support for "Vertos 100" drive ("ECS-AT") - it is very similar
- *       to the Longshine LCS-7260. Give feedback if you can - I never saw
- *       such a drive, and I have no specs.
- *
- *  4.2  Support for Teac 16-bit interface cards. Can't get auto-detected,
- *       so you have to jumper your card to 0x2C0. Still not 100% - come
- *       in contact if you can give qualified feedback.
- *       Use loglevel KERN_NOTICE with printk(). If you get annoyed by a
- *       flood of unwanted messages and the accompanied delay, try to read
- *       my documentation. Especially the Linux CDROM drivers have to do an
- *       important job for the newcomers, so the "distributed" version has
- *       to fit some special needs. Since generations, the flood of messages
- *       is user-configurable (even at runtime), but to get aware of this, one
- *       needs a special mental quality: the ability to read.
- *       
- *  4.3  CD200F does not like to receive a command while the drive is
- *       reading the ToC; still trying to solve it.
- *       Removed some redundant verify_area calls (yes, Heiko Eissfeldt
- *       is visiting all the Linux CDROM drivers ;-).
- *       
- *  4.4  Adapted one idea from tiensivu@pilot.msu.edu's "stripping-down"
- *       experiments: "KLOGD_PAUSE".
- *       Inhibited "play audio" attempts with data CDs. Provisions for a
- *       "data-safe" handling of "mixed" (data plus audio) Cds.
- *
- *  4.5  Meanwhile Gonzalo Tornaria <tornaria@cmat.edu.uy> (GTL) built a
- *       special end_request routine: we seem to have to take care for not
- *       to have two processes working at the request list. My understanding
- *       was and is that ll_rw_blk should not call do_sbpcd_request as long
- *       as there is still one call active (the first call will care for all
- *       outstanding I/Os, and if a second call happens, that is a bug in
- *       ll_rw_blk.c).
- *       "Check media change" without touching any drive.
- *
- *  4.6  Use a semaphore to synchronize multi-activity; elaborated by Rob
- *       Riggs <rriggs@tesser.com>. At the moment, we simply block "read"
- *       against "ioctl" and vice versa. This could be refined further, but
- *       I guess with almost no performance increase.
- *       Experiments to speed up the CD-55A; again with help of Rob Riggs
- *       (to be true, he gave both, idea & code. ;-)
- *
- *  4.61 Ported to Uniform CD-ROM driver by 
- *       Heiko Eissfeldt <heiko@colossus.escape.de> with additional
- *       changes by Erik Andersen <andersee@debian.org>
- *
- *  4.62 Fix a bug where playing audio left the drive in an unusable state.
- *         Heiko Eissfeldt <heiko@colossus.escape.de>
- *
- *  November 1999 -- Make kernel-parameter implementation work with 2.3.x 
- *	             Removed init_module & cleanup_module in favor of 
- *	             module_init & module_exit.
- *	             Torben Mathiasen <tmm@image.dk>
- *
- *  4.63 Bug fixes for audio annoyances, new legacy CDROM maintainer.
- *		Annoying things fixed:
- *		TOC reread on automated disk changes
- *		TOC reread on manual cd changes
- *		Play IOCTL tries to play CD before it's actually ready... sometimes.
- *		CD_AUDIO_COMPLETED state so workman (and other playes) can repeat play.
- *		Andrew J. Kroll <ag784@freenet.buffalo.edu> Wed Jul 26 04:24:10 EDT 2000
- *
- *  4.64 Fix module parameters - were being completely ignored.
- *	 Can also specify max_drives=N as a setup int to get rid of
- *	 "ghost" drives on crap hardware (aren't they all?)   Paul Gortmaker
- *
- *  TODO
- *     implement "read all subchannel data" (96 bytes per frame)
- *     remove alot of the virtual status bits and deal with hardware status
- *     move the change of cd for audio to a better place
- *     add debug levels to insmod parameters (trivial)
- *
- *     special thanks to Kai Makisara (kai.makisara@vtt.fi) for his fine
- *     elaborated speed-up experiments (and the fabulous results!), for
- *     the "push" towards load-free wait loops, and for the extensive mail
- *     thread which brought additional hints and bug fixes.

- *
- *  In any case, the race here would be much small than it was, and

- *
- *  The race could be: suppose CURRENT==NULL. We put our req in the list,

- * Attention! This file contains user-serviceable parts!
- * I recommend to make use of it...
- * If you feel helpless, look into Documentation/cdrom/sbpcd
- * (good idea anyway, at least before mailing me).
- *
- * The definitions for the first controller can get overridden by
- * the kernel command line ("lilo boot option").
- * Examples:
- *                                 sbpcd=0x300,LaserMate
- *                             or

- *                             or
- *                                 sbpcd=0x338,SoundScape
- *                             or
- *                                 sbpcd=0x2C0,Teac16bit
- *
- * If sbpcd gets used as a module, you can load it with
- *     insmod sbpcd.o sbpcd=0x300,0
- * or
- *     insmod sbpcd.o sbpcd=0x230,1
- * or
- *     insmod sbpcd.o sbpcd=0x338,2
- * or
- *     insmod sbpcd.o sbpcd=0x2C0,3
- * respective to override the configured address and type.
- */
-
-/*
- * define your CDROM port base address as CDROM_PORT
- * and specify the type of your interface card as SBPRO.
- *
- * address:
- * ========
- * SBPRO type addresses typically are 0x0230 (=0x220+0x10), 0x0250, ...
- * LASERMATE type (CI-101P, WDH-7001C) addresses typically are 0x0300, ...
- * SOUNDSCAPE addresses are from the LASERMATE type and range. You have to
- * specify the REAL address here, not the configuration port address. Look
- * at the CDROM driver's invoking line within your DOS CONFIG.SYS, or let
- * sbpcd auto-probe, if you are not firm with the address.
- * There are some soundcards on the market with 0x0630, 0x0650, ...; their
- * type is not obvious (both types are possible).
- *
- * example: if your SBPRO audio address is 0x220, specify 0x230 and SBPRO 1.
- *          if your soundcard has its CDROM port above 0x300, specify
- *          that address and try SBPRO 0 first.
- *          if your SoundScape configuration port is at 0x330, specify
- *          0x338 and SBPRO 2.
- *
- * interface type:
- * ===============
- * set SBPRO to 1 for "true" SoundBlaster card
- * set SBPRO to 0 for "compatible" soundcards and
- *                for "poor" (no sound) interface cards.
- * set SBPRO to 2 for Ensonic SoundScape or SPEA Media FX cards
- * set SBPRO to 3 for Teac 16bit interface cards
- *
- * Almost all "compatible" sound boards need to set SBPRO to 0.
- * If SBPRO is set wrong, the drives will get found - but any
- * data access will give errors (audio access will work).
- * The "OmniCD" no-sound interface card from CreativeLabs and most Teac
- * interface cards need SBPRO 1.
- *
- * sound base:
- * ===========
- * The SOUND_BASE definition tells if we should try to turn the CD sound
- * channels on. It will only be of use regarding soundcards with a SbPro
- * compatible mixer.
- *
- * Example: #define SOUND_BASE 0x220 enables the sound card's CD channels
- *          #define SOUND_BASE 0     leaves the soundcard untouched

- *
- *
- *  This driver is based on pre-works by Eberhard Moenkeberg (emoenke@gwdg.de);
- *  it was developed under use of mcd.c from Martin Harriss, with help of
- *  Eric van der Maarel (H.T.M.v.d.Maarel@marin.nl).
- *
- *  It is planned to include these routines into sbpcd.c later - to make
- *  a "mixed use" on one cable possible for all kinds of drives which use
- *  the SoundBlaster/Panasonic style CDROM interface. But today, the
- *  ability to install directly from CDROM is more important than flexibility.

- *  History:
- *  1.1 First public release with kernel version 1.3.7.
- *      Written by Vadim Model.
- *  1.2 Added detection and configuration of cdrom interface
- *      on ISP16 soundcard.
- *      Allow for command line options: sjcd=<io_base>,<irq>,<dma>
- *  1.3 Some minor changes to README.sjcd.
- *  1.4 MSS Sound support!! Listen to a CD through the speakers.
- *  1.5 Module support and bugfixes.
- *      Tray locking.
- *  1.6 Removed ISP16 code from this driver.
- *      Allow only to set io base address on command line: sjcd=<io_base>
- *      Changes to Documentation/cdrom/sjcd
- *      Added cleanup after any error in the initialisation.
- *  1.7 Added code to set the sector size tables to prevent the bug present in 
- *      the previous version of this driver.  Coded added by Anthony Barbachan 
- *      from bugfix tip originally suggested by Alan Cox.
- *
- *  November 1999 -- Make kernel-parameter implementation work with 2.3.x 
- *	             Removed init_module & cleanup_module in favor of 
- *	             module_init & module_exit.
- *	             Torben Mathiasen <tmm@image.dk>

- * Sony CDU-535 interface device driver
- *
- * This is a modified version of the CDU-31A device driver (see below).
- * Changes were made using documentation for the CDU-531 (which Sony
- * assures me is very similar to the 535) and partial disassembly of the
- * DOS driver.  I used Minyard's driver and replaced the CDU-31A
- * commands with the CDU-531 commands.  This was complicated by a different
- * interface protocol with the drive.  The driver is still polled.
- *
- * Data transfer rate is about 110 Kb/sec, theoretical maximum is 150 Kb/sec.
- * I tried polling without the sony_sleep during the data transfers but
- * it did not speed things up any.
- *
- * 1993-05-23 (rgj) changed the major number to 21 to get rid of conflict
- * with CDU-31A driver.  This is the also the number from the Linux
- * Device Driver Registry for the Sony Drive.  Hope nobody else is using it.
- *
- * 1993-08-29 (rgj) remove the configuring of the interface board address
- * from the top level configuration, you have to modify it in this file.
- *
- * 1995-01-26 Made module-capable (Joel Katz <Stimpson@Panix.COM>)
- *
- * 1995-05-20
- *  Modified to support CDU-510/515 series
- *      (Claudio Porfiri<C.Porfiri@nisms.tei.ericsson.se>)
- *  Fixed to report verify_area() failures
- *      (Heiko Eissfeldt <heiko@colossus.escape.de>)
- *
- * 1995-06-01
- *  More changes to support CDU-510/515 series
- *      (Claudio Porfiri<C.Porfiri@nisms.tei.ericsson.se>)
- *
- * November 1999 -- Make kernel-parameter implementation work with 2.3.x 
- *	            Removed init_module & cleanup_module in favor of 
- *	            module_init & module_exit.
- *                  Torben Mathiasen <tmm@image.dk>
- *
- * September 2003 - Fix SMP support by removing cli/sti calls.

- *
- * Things to do:
- *  - handle errors and status better, put everything into a single word
- *  - use interrupts (code mostly there, but a big hole still missing)
- *  - handle multi-session CDs?
- *  - use DMA?
- *
- *  Known Bugs:

- *------------------------------------------------------------------------
- * Sony CDROM interface device driver.
- *
- * Corey Minyard (minyard@wf-rch.cirr.com) (CDU-535 complaints to Ken above)
- *
- * Colossians 3:17
- *
- * The Sony interface device driver handles Sony interface CDROM
- * drives and provides a complete block-level interface as well as an
- * ioctl() interface compatible with the Sun (as specified in
- * include/linux/cdrom.h).  With this interface, CDROMs can be
- * accessed and standard audio CDs can be played back normally.
- *
- * This interface is (unfortunately) a polled interface.  This is
- * because most Sony interfaces are set up with DMA and interrupts
- * disables.  Some (like mine) do not even have the capability to
- * handle interrupts or DMA.  For this reason you will see a bit of
- * the following:
- *
- *   snap = jiffies;
- *   while (jiffies-snap < SONY_JIFFIES_TIMEOUT)
- *   {
- *		if (some_condition())
- *         break;
- *      sony_sleep();
- *   }
- *   if (some_condition not met)
- *   {
- *      return an_error;
- *   }
- *
- * This ugly hack waits for something to happen, sleeping a little
- * between every try.  (The conditional is written so that jiffies
- * wrap-around is handled properly.)
- *
- * One thing about these drives: They talk in MSF (Minute Second Frame) format.
- * There are 75 frames a second, 60 seconds a minute, and up to 75 minutes on a
- * disk.  The funny thing is that these are sent to the drive in BCD, but the
- * interface wants to see them in decimal.  A lot of conversion goes on.

+/* lasi_82596.c -- driver for the intel 82596 ethernet controller, as
+   munged into HPPA boxen .
+
+   This driver is based upon 82596.c, original credits are below...
+   but there were too many hoops which HP wants jumped through to
+   keep this code in there in a sane manner.
+
+   3 primary sources of the mess --
+   1) hppa needs *lots* of cacheline flushing to keep this kind of
+   MMIO running.
+
+   2) The 82596 needs to see all of its pointers as their physical
+   address.  Thus virt_to_bus/bus_to_virt are *everywhere*.
+
+   3) The implementation HP is using seems to be significantly pickier
+   about when and how the command and RX units are started.  some
+   command ordering was changed.
+
+   Examination of the mach driver leads one to believe that there
+   might be a saner way to pull this off...  anyone who feels like a
+   full rewrite can be my guest.
+
+   Split 02/13/2000 Sam Creasey (sammy@oh.verio.com)
+
+   02/01/2000  Initial modifications for parisc by Helge Deller (deller@gmx.de)

+
+/* 82596.c: A generic 82596 ethernet driver for linux. */
+/*
+   Based on Apricot.c
+   Written 1994 by Mark Evans.
+   This driver is for the Apricot 82596 bus-master interface
+
+   Modularised 12/94 Mark Evans
+
+
+   Modified to support the 82596 ethernet chips on 680x0 VME boards.
+   by Richard Hirst <richard@sleepie.demon.co.uk>
+   Renamed to be 82596.c
+
+   980825:  Changed to receive directly in to sk_buffs which are
+   allocated at open() time.  Eliminates copy on incoming frames
+   (small ones are still copied).  Shared data now held in a
+   non-cached page, so we can run on 68060 in copyback mode.
+
+   TBD:
+   * look at deferring rx frames rather than discarding (as per tulip)
+   * handle tx ring full as per tulip
+   * performace test to tune rx_copybreak
+
+   Most of my modifications relate to the braindead big-endian
+   implementation by Intel.  When the i596 is operating in
+   'big-endian' mode, it thinks a 32 bit value of 0x12345678
+   should be stored as 0x56781234.  This is a real pain, when
+   you have linked lists which are shared by the 680x0 and the
+   i596.

-=========================================================================
- r8169.c: A RealTek RTL-8169 Gigabit Ethernet driver for Linux kernel 2.4.x.
- --------------------------------------------------------------------
-
- History:
- Feb  4 2002	- created initially by ShuChen <shuchen@realtek.com.tw>.
- May 20 2002	- Add link status force-mode and TBI mode support.
-	2004	- Massive updates. See kernel SCM system for details.
-=========================================================================
-  1. [DEPRECATED: use ethtool instead] The media can be forced in 5 modes.
-	 Command: 'insmod r8169 media = SET_MEDIA'
-	 Ex:	  'insmod r8169 media = 0x04' will force PHY to operate in 100Mpbs Half-duplex.
-
-	 SET_MEDIA can be:
- 		_10_Half	= 0x01
- 		_10_Full	= 0x02
- 		_100_Half	= 0x04
- 		_100_Full	= 0x08
- 		_1000_Full	= 0x10
-
-  2. Support TBI mode.
-=========================================================================
-VERSION 1.1	<2002/10/4>
-
-	The bit4:0 of MII register 4 is called "selector field", and have to be
-	00001b to indicate support of IEEE std 802.3 during NWay process of
-	exchanging Link Code Word (FLP).
-
-VERSION 1.2	<2002/11/30>
-
-	- Large style cleanup
-	- Use ether_crc in stock kernel (linux/crc32.h)
-	- Copy mc_filter setup code from 8139cp
-	  (includes an optimization, and avoids set_bit use)
-
-VERSION 1.6LK	<2004/04/14>
-
-	- Merge of Realtek's version 1.6
-	- Conversion to DMA API
-	- Suspend/resume
-	- Endianness
-	- Misc Rx/Tx bugs
-
-VERSION 2.2LK	<2005/01/25>
-
-	- RX csum, TX csum/SG, TSO
-	- VLAN
-	- baby (< 7200) Jumbo frames support
-	- Merge of Realtek's version 2.2 (new phy)

+ * @sdp: The GFS2 superblock
+ *
+ * This is complex.  We need to reserve room for all our currently used
+ * metadata buffers (e.g. normal file I/O rewriting file time stamps) and 
+ * all our journaled data buffers for journaled files (e.g. files in the 
+ * meta_fs like rindex, or files for which chattr +j was done.)
+ * If we don't reserve enough space, gfs2_log_refund and gfs2_log_flush
+ * will count it as free space (sd_log_blks_free) and corruption will follow.
+ *
+ * We can have metadata bufs and jdata bufs in the same journal.  So each
+ * type gets its own log header, for which we need to reserve a block.
+ * In fact, each type has the potential for needing more than one header 
+ * in cases where we have more buffers than will fit on a journal page.
+ * Metadata journal entries take up half the space of journaled buffer entries.
+ * Thus, metadata entries have buf_limit (502) and journaled buffers have
+ * databuf_limit (251) before they cause a wrap around.
+ *
+ * Also, we need to reserve blocks for revoke journal entries and one for an
+ * overall header for the lot.

+ * It is convenient to program the OATRAN register so that

+ * The only hard restrictions on the value of OATRAN is that

+ * to I/O accesses.
+ *
+ * To program OATRAN to make Athena virtual address space
+ * and PCI address space have the same values, OATRAN
+ * is to be programmed to 0xB8000000. The top seven
+ * bits of the value mimic the seven bits clipped off
+ * by the PCI Host controller.

+ * With OATRAN at the said value, when the CPU does

+ * SMP/VPE-safe functions to access "registers" (see note).
+ *
+ * NOTES:
+* - These macros use ll/sc instructions, so it is your responsibility to
+ * ensure these are available on your platform before including this file.
+ * - The MIPS32 spec states that ll/sc results are undefined for uncached
+ * accesses. This means they can't be used on HW registers accessed
+ * through kseg1. Code which requires these macros for this purpose must
+ * front-end the registers with cached memory "registers" and have a single
+ * thread update the actual HW registers.
+ * - A maximum of 2k of code can be inserted between ll and sc. Every
+ * memory accesses between the instructions will increase the chance of
+ * sc failing and having to loop.
+ * - When using custom_read_reg32/custom_write_reg32 only perform the
+ * necessary logical operations on the register value in between these
+ * two calls. All other logic should be performed before the first call.
+  * - There is a bug on the R10000 chips which has a workaround. If you
+ * are affected by this bug, make sure to define the symbol 'R10000_LLSC_WAR'
+ * to be non-zero.  If you are using this header from within linux, you may
+ * include <asm/war.h> before including this file to have this defined
+ * appropriately for you.

+ * Notes:
+ *  1) The SPI registers are split into two blocks, one offset from the
+ *     MSP_SPI_BASE by 0x00 and the other offset from the MSP_SPI_BASE by
+ *     0x68.  The SPI driver definitions for the register must be aware
+ *     of this.
+ *  2) The block copy engine register are divided into two regions, one
+ *     for the control/configuration of the engine proper and one for the
+ *     values of the descriptors used in the copy process.  These have
+ *     different base defines (CTRL_BASE vs DESC_BASE)
+ *  3) These constants are for physical addresses which means that they
+ *     work correctly with "ioremap" and friends.  This means that device
+ *     drivers will need to remap these addresses using ioremap and perhaps
+ *     the readw/writew macros.  Or they could use the regptr() macro
+ *     defined below, but the readw/writew calls are the correct thing.
+ *  4) The UARTs have an additional status register offset from the base
+ *     address.  This register isn't used in the standard 8250 driver but
+ *     may be used in other software.  Consult the hardware datasheet for
+ *     offset details.
+ *  5) For some unknown reason the security engine (MSP_SEC_BASE) registers
+ *     start at an offset of 0x84 from the base address but the block of
+ *     registers before this is reserved for the security engine.  The
+ *     driver will have to be aware of this but it makes the register
+ *     definitions line up better with the documentation.

- *  TASK_INTERACTIVE(-20): [1,1,1,1,1,1,1,1,1,0,0]

- * (the X axis represents the possible -5 ... 0 ... +5 dynamic

- *  task is rated interactive.)
- *
- * Ie. nice +19 tasks can never get 'interactive' enough to be
