+ * APEI Generic Hardware Error Source support
+ *
+ * Generic Hardware Error Source provides a way to report platform
+ * hardware errors (such as that from chipset). It works in so called
+ * "Firmware First" mode, that is, hardware errors are reported to
+ * firmware firstly, then reported to Linux by firmware. This way,
+ * some non-standard hardware error registers or non-standard hardware
+ * link can be checked by firmware to produce more hardware error
+ * information for Linux.
+ *
+ * For more information about Generic Hardware Error Source, please
+ * refer to ACPI Specification version 4.0, section 17.3.2.6
+ *
+ * Now, only SCI notification type and memory errors are
+ * supported. More notification type and hardware error type will be
+ * added later.

+ *	Partly done: 	hooks so you can pull off frames to non tty devs
+ *	Restart DLCI 0 when it closes ?
+ *	Test basic encoding
+ *	Improve the tx engine
+ *	Resolve tx side locking by adding a queue_head and routing
+ *		all control traffic via it
+ *	General tidy/document
+ *	Review the locking/move to refcounts more (mux now moved to an
+ *		alloc/free model ready)
+ *	Use newest tty open/close port helpers and install hooks
+ *	What to do about power functions ?
+ *	Termios setting and negotiation
+ *	Do we need a 'which mux are you' ioctl to correlate mux and tty sets

+ * Software methods, why they are needed, and how they all work:
+ *
+ * NV04 and NV05 keep most of the state in PGRAPH context itself, but some
+ * 2d engine settings are kept inside the grobjs themselves. The grobjs are
+ * 3 words long on both. grobj format on NV04 is:
+ *
+ * word 0:
+ *  - bits 0-7: class
+ *  - bit 12: color key active
+ *  - bit 13: clip rect active
+ *  - bit 14: if set, destination surface is swizzled and taken from buffer 5
+ *            [set by NV04_SWIZZLED_SURFACE], otherwise it's linear and taken
+ *            from buffer 0 [set by NV04_CONTEXT_SURFACES_2D or
+ *            NV03_CONTEXT_SURFACE_DST].
+ *  - bits 15-17: 2d operation [aka patch config]
+ *  - bit 24: patch valid [enables rendering using this object]
+ *  - bit 25: surf3d valid [for tex_tri and multitex_tri only]
+ * word 1:
+ *  - bits 0-1: mono format
+ *  - bits 8-13: color format
+ *  - bits 16-31: DMA_NOTIFY instance
+ * word 2:
+ *  - bits 0-15: DMA_A instance
+ *  - bits 16-31: DMA_B instance
+ *
+ * On NV05 it's:
+ *
+ * word 0:
+ *  - bits 0-7: class
+ *  - bit 12: color key active
+ *  - bit 13: clip rect active
+ *  - bit 14: if set, destination surface is swizzled and taken from buffer 5
+ *            [set by NV04_SWIZZLED_SURFACE], otherwise it's linear and taken
+ *            from buffer 0 [set by NV04_CONTEXT_SURFACES_2D or
+ *            NV03_CONTEXT_SURFACE_DST].
+ *  - bits 15-17: 2d operation [aka patch config]
+ *  - bits 20-22: dither mode
+ *  - bit 24: patch valid [enables rendering using this object]
+ *  - bit 25: surface_dst/surface_color/surf2d/surf3d valid
+ *  - bit 26: surface_src/surface_zeta valid
+ *  - bit 27: pattern valid
+ *  - bit 28: rop valid
+ *  - bit 29: beta1 valid
+ *  - bit 30: beta4 valid
+ * word 1:
+ *  - bits 0-1: mono format
+ *  - bits 8-13: color format
+ *  - bits 16-31: DMA_NOTIFY instance
+ * word 2:
+ *  - bits 0-15: DMA_A instance
+ *  - bits 16-31: DMA_B instance
+ *
+ * NV05 will set/unset the relevant valid bits when you poke the relevant
+ * object-binding methods with object of the proper type, or with the NULL
+ * type. It'll only allow rendering using the grobj if all needed objects
+ * are bound. The needed set of objects depends on selected operation: for
+ * example rop object is needed by ROP_AND, but not by SRCCOPY_AND.
+ *
+ * NV04 doesn't have these methods implemented at all, and doesn't have the
+ * relevant bits in grobj. Instead, it'll allow rendering whenever bit 24
+ * is set. So we have to emulate them in software, internally keeping the
+ * same bits as NV05 does. Since grobjs are aligned to 16 bytes on nv04,
+ * but the last word isn't actually used for anything, we abuse it for this
+ * purpose.
+ *
+ * Actually, NV05 can optionally check bit 24 too, but we disable this since
+ * there's no use for it.
+ *
+ * For unknown reasons, NV04 implements surf3d binding in hardware as an
+ * exception. Also for unknown reasons, NV04 doesn't implement the clipping
+ * methods on the surf3d object, so we have to emulate them too.

-	tristate "Aironet Arlan 655 & IC2200 DS support"
-	depends on ISA && !64BIT && WLAN
-	select WIRELESS_EXT
-	---help---
-	  Aironet makes Arlan, a class of wireless LAN adapters. These use the
-	  www.Telxon.com chip, which is also used on several similar cards.
-	  This driver is tested on the 655 and IC2200 series cards. Look at
-	  <http://www.ylenurme.ee/~elmer/655/> for the latest information.
-
-	  The driver is built as two modules, arlan and arlan-proc. The latter
-	  is the /proc interface and is not needed most of time.
-
-	  On some computers the card ends up in non-valid state after some
-	  time. Use a ping-reset script to clear it.

 BATMAN-ADV
 ----------
 
-Batman-advanced is a new approach to wireless networking which does no longer
-operate on the IP basis. Unlike B.A.T.M.A.N, 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 protocols won't be
-affected by any changes within the network. You can run almost any protocol
-above B.A.T.M.A.N. Advanced, prominent examples are: IPv4, IPv6, DHCP, IPX.

+Batman advanced was implemented as a Linux kernel driver  to  re-

+vpn,  etc ... (anything with ethernet-style layer 2).
 
-USAGE
------
+CONFIGURATION
+-------------
 
-insmod the batman-adv.ko in your kernel:
+Load the batman-adv module into your kernel:
 
 # insmod batman-adv.ko
 
-the module is now waiting for activation. You must add some interfaces
-on which batman can operate. Each interface must be added separately:
+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).
 
-# echo wlan0 > /proc/net/batman-adv/interfaces
+By reading the "iface_status" file you can check its status:
 
-( # echo wlan1 > /proc/net/batman-adv/interfaces )
-( # echo eth0 > /proc/net/batman-adv/interfaces )
-( ... )
+# cat /sys/class/net/eth0/batman_adv/iface_status
+# active
 
-Now batman starts broadcasting on this interface.
-You can now view the table of originators (mesh participants) with:
+To deactivate an interface you have  to  write  "none"  into  its
+"mesh_iface" file:
 
-# cat /proc/net/batman-adv/originators
+# echo none > /sys/class/net/eth0/batman_adv/mesh_iface
 
-The module will create a new interface "bat0", which can be used as a
-regular interface:
 
-# ifconfig bat0 inet 192.168.0.1 up
-# ping 192.168.0.2
-...
+All  mesh  wide  settings  can be found in batman's own interface
+folder:
 
-If you want topology visualization, your meshnode must be configured
-as VIS-server:
+#  ls  /sys/class/net/bat0/mesh/
+#  aggregate_ogm   originators        transtable_global  vis_mode
+#  orig_interval   transtable_local   vis_data
 
-# echo "server" > /proc/net/batman-adv/vis
 
-Each node is either configured as "server" or as "client" (default:
-"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.
+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:
 
-When configured as server, you can get a topology snapshot of your mesh:
+# cat /sys/class/net/bat0/mesh/originators
 
-# cat /proc/net/batman-adv/vis
+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):
 
-The output is in a generic raw format. Use the batctl tool (See below)
-to convert this to other formats more suitable for graphing, eg
-graphviz dot, or JSON data-interchange format.
+# cat /sys/class/net/bat0/mesh/orig_interval
+# status: 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 responsive to
-topology changes, but will also increase the overhead. Please make sure
-that all nodes in your mesh use the same interval. The default value
-is 1000 ms (1 second).
+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.
 
-# echo 1000 > /proc/net/batman-adv/orig_interval
+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):
 
-To deactivate batman, do:
+# 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/class/net/bat0/mesh/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
 -----------------

-kernel log. Depending on your operating system distribution this can be

+     *    (Hack by Paul.Russell@rustcorp.com.au)
+     * 2) Set *start = an address within the buffer.

+KernelVersion:	2.6.35
+Contact:	linux-iio@vger.kernel.org
+Description:
+		Some devices have internal clocks.  This parameter sets the

+		simply controlling when the input is sampled.  As this
+		effects datardy triggers, hardware buffers and the sysfs
+		direct access interfaces, it may be found in any of the
+		relevant directories.  If it effects all of the above
+		then it is to be found in the base device directory as here.

+RAR Handler (memrar) Driver TODO Items
+======================================
+
+Maintainer: Ossama Othman <ossama.othman@intel.com>
+
+memrar.h
+--------
+1. This header exposes the driver's user space and kernel space
+   interfaces.  It should be moved to <linux/rar/memrar.h>, or
+   something along those lines, when this memrar driver is moved out
+   of `staging'.
+     a. It would be ideal if staging/rar_register/rar_register.h was
+        moved to the same directory.
+
+memrar_allocator.[ch]
+---------------------
+1. Address potential fragmentation issues with the memrar_allocator.
+
+2. Hide struct memrar_allocator details/fields.  They need not be
+   exposed to the user.
+     a. Forward declare struct memrar_allocator.
+     b. Move all three struct definitions to `memrar_allocator.c'
+        source file.
+     c. Add a memrar_allocator_largest_free_area() function, or
+        something like that to get access to the value of the struct
+        memrar_allocator "largest_free_area" field.  This allows the
+        struct memrar_allocator fields to be completely hidden from
+        the user.  The memrar_handler code really only needs this for
+        statistic gathering on-demand.
+     d. Do the same for the "capacity" field as the
+        "largest_free_area" field.
+
+3. Move memrar_allocator.* to kernel `lib' directory since it is HW
+   neutral.
+     a. Alternatively, use lib/genalloc.c instead.
+     b. A kernel port of Doug Lea's malloc() implementation may also
+        be an option.
+
+memrar_handler.c
+----------------
+1. Split user space interface (ioctl code) from core/kernel code,
+   e.g.:
+     memrar_handler.c -> memrar_core.c, memrar_user.c

+What:		/dev/memrar
+Date:		March 2010
+KernelVersion:	Kernel version this feature first showed up in.
+Contact:	Ossama Othman <ossama.othman@intel.com>
+Description:	The Intel Moorestown Restricted Access Region (RAR)
+		Handler driver exposes an ioctl() based interface that
+		allows a user to reserve and release blocks of RAR
+		memory.
+
+		Note:  A sysfs based one was not appropriate for the
+		RAR handler's usage model.
+
+		=========================================================
+				ioctl() Requests
+		=========================================================
+		RAR_HANDLER_RESERVE
+		-------------------
+		Description:	Reserve RAR block.
+		Type:		struct RAR_block_info
+		Direction:	in/out
+		Errors:		EINVAL (invalid RAR type or size)
+				ENOMEM (not enough RAR memory)
+
+		RAR_HANDLER_STAT
+		----------------
+		Description:	Get RAR statistics.
+		Type:		struct RAR_stat
+		Direction:	in/out
+		Errors:		EINVAL (invalid RAR type)
+
+		RAR_HANDLER_RELEASE
+		-------------------
+		Description:	Release previously reserved RAR block.
+		Type:		32 bit unsigned integer
+				(e.g. uint32_t), i.e the RAR "handle".
+		Direction:	in
+		Errors:		EINVAL (invalid RAR handle)
+
+
+		=========================================================
+			ioctl() Request Parameter Types
+		=========================================================
+		The structures referred to above are defined as
+		follows:
+
+		/**
+		 * struct RAR_block_info - user space struct that
+		 *			   describes RAR buffer
+		 * @type:	Type of RAR memory (e.g.,
+		 *		RAR_TYPE_VIDEO or RAR_TYPE_AUDIO) [in]
+		 * @size:	Requested size of a block in bytes to
+		 *		be reserved in RAR. [in]
+		 * @handle:	Handle that can be used to refer to
+		 *		reserved block. [out]
+		 *
+		 * This is the basic structure exposed to the user
+		 * space that describes a given RAR buffer.  It used
+		 * as the parameter for the RAR_HANDLER_RESERVE ioctl.
+		 * The buffer's underlying bus address is not exposed
+		 * to the user.  User space code refers to the buffer
+		 * entirely by "handle".
+		 */
+		struct RAR_block_info {
+			__u32 type;
+			__u32 size;
+			__u32 handle;
+		};
+
+		/**
+		 * struct RAR_stat - RAR statistics structure
+		 * @type:		Type of RAR memory (e.g.,
+		 *			RAR_TYPE_VIDEO or
+		 *			RAR_TYPE_AUDIO) [in]
+		 * @capacity:		Total size of RAR memory
+		 *			region. [out]
+		 * @largest_block_size:	Size of the largest reservable
+		 *			block. [out]
+		 *
+		 * This structure is used for RAR_HANDLER_STAT ioctl.
+		 */
+		struct RAR_stat {
+			__u32 type;
+			__u32 capacity;
+			__u32 largest_block_size;
+		};
+
+		Lastly, the RAR_HANDLER_RELEASE ioctl expects a
+		"handle" to the RAR block of memory.  It is a 32 bit
+		unsigned integer.

- * Revision History:
- *
- *   08-Nov-97 15:14:47   John Markus Bjørndalen <johnm@cs.uit.no>
- *    - Fixed some bugs in netwave_rx and cleaned it up a bit. 
- *      (One of the bugs would have destroyed packets when receiving
- *      multiple packets per interrupt). 
- *    - Cleaned up parts of newave_hw_xmit. 
- *    - A few general cleanups. 
- *   24-Oct-97 13:17:36   Dag Brattli <dagb@cs.uit.no>
- *    - Fixed netwave_rx receive function (got updated docs)
- *   Others:
- *    - Changed name from xircnw to netwave, take a look at 
- *      http://www.netwave-wireless.com
- *    - Some reorganizing of the code
- *    - Removed possible race condition between interrupt handler and transmit
- *      function
- *    - Started to add wireless extensions, but still needs some coding
- *    - Added watchdog for better handling of transmission timeouts 
- *      (hopefully this works better)

-TODO:
-	- Rx block size is limited to < 2048, hardware bug?
-	- Group size is limited to < page size, kernel alloc/mmap API issues
-	- test whether Tx is transmitting data from provided buffers
-	- handle device unplug case
-	- handle temperature above threshold
-	- use bus address instead of physical address for DMA
-	- support for snapshot mode
-	- audit userspace interfaces
-	- get reserved major/minor if needed

-	  Say Y if you have a Metricom radio and intend to use Starmode Radio
-	  IP. STRIP is a radio protocol developed for the MosquitoNet project
-	  to send Internet traffic using Metricom radios.  Metricom radios are
-	  small, battery powered, 100kbit/sec packet radio transceivers, about
-	  the size and weight of a cellular telephone. (You may also have heard
-	  them called "Metricom modems" but we avoid the term "modem" because
-	  it misleads many people into thinking that you can plug a Metricom
-	  modem into a phone line and use it as a modem.)
-
-	  You can use STRIP on any Linux machine with a serial port, although
-	  it is obviously most useful for people with laptop computers. If you
-	  think you might get a Metricom radio in the future, there is no harm
-	  in saying Y to STRIP now, except that it makes the kernel a bit
-	  bigger.
-
-	  To compile this as a module, choose M here: the module will be
-	  called strip.

- * strip.c	This module implements Starmode Radio IP (STRIP)
- *		for kernel-based devices like TTY.  It interfaces between a
- *		raw TTY, and the kernel's INET protocol layers (via DDI).
- *
- * Version:	@(#)strip.c	1.3	July 1997
- *
- * Author:	Stuart Cheshire <cheshire@cs.stanford.edu>
- *
- * Fixes:	v0.9 12th Feb 1996 (SC)
- *		New byte stuffing (2+6 run-length encoding)
- *		New watchdog timer task
- *		New Protocol key (SIP0)
- *		
- *		v0.9.1 3rd March 1996 (SC)
- *		Changed to dynamic device allocation -- no more compile
- *		time (or boot time) limit on the number of STRIP devices.
- *		
- *		v0.9.2 13th March 1996 (SC)
- *		Uses arp cache lookups (but doesn't send arp packets yet)
- *		
- *		v0.9.3 17th April 1996 (SC)
- *		Fixed bug where STR_ERROR flag was getting set unneccessarily
- *		(causing otherwise good packets to be unneccessarily dropped)
- *		
- *		v0.9.4 27th April 1996 (SC)
- *		First attempt at using "&COMMAND" Starmode AT commands
- *		
- *		v0.9.5 29th May 1996 (SC)
- *		First attempt at sending (unicast) ARP packets
- *		
- *		v0.9.6 5th June 1996 (Elliot)
- *		Put "message level" tags in every "printk" statement
- *		
- *		v0.9.7 13th June 1996 (laik)
- *		Added support for the /proc fs
- *
- *              v0.9.8 July 1996 (Mema)
- *              Added packet logging
- *
- *              v1.0 November 1996 (SC)
- *              Fixed (severe) memory leaks in the /proc fs code
- *              Fixed race conditions in the logging code
- *
- *              v1.1 January 1997 (SC)
- *              Deleted packet logging (use tcpdump instead)
- *              Added support for Metricom Firmware v204 features
- *              (like message checksums)
- *
- *              v1.2 January 1997 (SC)
- *              Put portables list back in
- *
- *              v1.3 July 1997 (SC)
- *              Made STRIP driver set the radio's baud rate automatically.
- *              It is no longer necessarily to manually set the radio's
- *              rate permanently to 115200 -- the driver handles setting
- *              the rate automatically.

-/*
- * Note: manual_dev_addr hack
- * 
- * It is not possible to change the hardware address of a Metricom radio,
- * or to send packets with a user-specified hardware source address, thus
- * trying to manually set a hardware source address is a questionable
- * thing to do.  However, if the user *does* manually set the hardware
- * source address of a STRIP interface, then the kernel will believe it,
- * and use it in certain places. For example, the hardware address listed
- * by ifconfig will be the manual address, not the true one.
- * (Both addresses are listed in /proc/net/strip.)
- * Also, ARP packets will be sent out giving the user-specified address as
- * the source address, not the real address. This is dangerous, because
- * it means you won't receive any replies -- the ARP replies will go to
- * the specified address, which will be some other radio. The case where
- * this is useful is when that other radio is also connected to the same
- * machine. This allows you to connect a pair of radios to one machine,
- * and to use one exclusively for inbound traffic, and the other
- * exclusively for outbound traffic. Pretty neat, huh?
- * 
- * Here's the full procedure to set this up:
- * 
- * 1. "slattach" two interfaces, e.g. st0 for outgoing packets,
- *    and st1 for incoming packets
- * 
- * 2. "ifconfig" st0 (outbound radio) to have the hardware address
- *    which is the real hardware address of st1 (inbound radio).
- *    Now when it sends out packets, it will masquerade as st1, and
- *    replies will be sent to that radio, which is exactly what we want.
- * 
- * 3. Set the route table entry ("route add default ..." or
- *    "route add -net ...", as appropriate) to send packets via the st0
- *    interface (outbound radio). Do not add any route which sends packets
- *    out via the st1 interface -- that radio is for inbound traffic only.
- * 
- * 4. "ifconfig" st1 (inbound radio) to have hardware address zero.
- *    This tells the STRIP driver to "shut down" that interface and not
- *    send any packets through it. In particular, it stops sending the
- *    periodic gratuitous ARP packets that a STRIP interface normally sends.
- *    Also, when packets arrive on that interface, it will search the
- *    interface list to see if there is another interface who's manual
- *    hardware address matches its own real address (i.e. st0 in this
- *    example) and if so it will transfer ownership of the skbuff to
- *    that interface, so that it looks to the kernel as if the packet
- *    arrived on that interface. This is necessary because when the
- *    kernel sends an ARP packet on st0, it expects to get a reply on
- *    st0, and if it sees the reply come from st1 then it will ignore
- *    it (to be accurate, it puts the entry in the ARP table, but
- *    labelled in such a way that st0 can't use it).
- * 
- * Thanks to Petros Maniatis for coming up with the idea of splitting
- * inbound and outbound traffic between two interfaces, which turned
- * out to be really easy to implement, even if it is a bit of a hack.
- * 
- * Having set a manual address on an interface, you can restore it
- * to automatic operation (where the address is automatically kept
- * consistent with the real address of the radio) by setting a manual
- * address of all ones, e.g. "ifconfig st0 hw strip FFFFFFFFFFFF"
- * This 'turns off' manual override mode for the device address.
- * 
- * Note: The IEEE 802 headers reported in tcpdump will show the *real*
- * radio addresses the packets were sent and received from, so that you
- * can see what is really going on with packets, and which interfaces
- * they are really going through.

+TODO:
+
+1. A per-device/tty port context required to support multiple devices
+on same platform.
+
+2. REMOVE the sysfs entry PID passing mechanism, since there should
+be a better way to request user-space to install line discipline.
+
+3. Re-view/Re-work on the locking.
+
+4. Re-structure to make the ldisc driver more generic for chipsets which mux
+multiple connectivity (BT, FM, GPS) upon 1 TTY port.
+
+5. Step up and maintain this driver to ensure that it continues
+to work.  Having the hardware for this is pretty much a
+requirement.  If this does not happen, the will be removed in
+the 2.6.35 kernel release.
+
+Please send patches to Greg Kroah-Hartman <greg@kroah.com>.

-A single command encodes one contiguous horizontal line of pixels

-The function fills the supplied command buffer, providing information
-on where it left off, so the client may call in again with additional
-buffers if the line will take several buffers to complete.
-
-A single command can transmit a maximum of 256 pixels,

-To the hardware, 0 for a size byte means 256
-
-Rather than 256 pixel commands which are either rl or raw encoded,
-the rlx command simply assumes alternating raw and rl spans within one cmd.
-This has a slightly larger header overhead, but produces more even results.
-It also processes all data (read and write) in a single pass.
-Performance benchmarks of common cases show it having just slightly better

+ * (the protocol doesn't require this, but we enforce it to allow
+ * multiple buffers to be potentially encoded and sent in parallel).
+ * A single command encodes one contiguous horizontal line of pixels
+ *
+ * The function relies on the client to do all allocation, so that
+ * rendering can be done directly to output buffers (e.g. USB URBs).
+ * The function fills the supplied command buffer, providing information
+ * on where it left off, so the client may call in again with additional
+ * buffers if the line will take several buffers to complete.
+ *
+ * A single command can transmit a maximum of 256 pixels,
+ * regardless of the compression ratio (protocol design limit).
+ * To the hardware, 0 for a size byte means 256
+ * 
+ * Rather than 256 pixel commands which are either rl or raw encoded,
+ * the rlx command simply assumes alternating raw and rl spans within one cmd.
+ * This has a slightly larger header overhead, but produces more even results.
+ * It also processes all data (read and write) in a single pass.
+ * Performance benchmarks of common cases show it having just slightly better
+ * compression than 256 pixel raw -or- rle commands, with similar CPU consumpion.
+ * But for very rl friendly data, will compress not quite as well.

-/*
- * This driver provides a Linux interface to the WaveLAN ISA hardware.
- * The WaveLAN is a product of Lucent (http://www.wavelan.com/).
- * This division was formerly part of NCR and then AT&T.
- * WaveLANs are also distributed by DEC (RoamAbout DS) and Digital Ocean.
- *
- * To learn how to use this driver, read the NET3 HOWTO.
- * If you want to exploit the many other functionalities, read the comments
- * in the code.
- *
- * This driver is the result of the effort of many people (see below).
- */
-
-/* ------------------------ SPECIFIC NOTES ------------------------ */
-/*
- * Web page
- * --------
- *	I try to maintain a web page with the Wireless LAN Howto at :
- *	    http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html
- *
- * SMP
- * ---
- *	We now are SMP compliant (I eventually fixed the remaining bugs).
- *	The driver has been tested on a dual P6-150 and survived my usual
- *	set of torture tests.
- *	Anyway, I spent enough time chasing interrupt re-entrancy during
- *	errors or reconfigure, and I designed the locked/unlocked sections
- *	of the driver with great care, and with the recent addition of
- *	the spinlock (thanks to the new API), we should be quite close to
- *	the truth.
- *	The SMP/IRQ locking is quite coarse and conservative (i.e. not fast),
- *	but better safe than sorry (especially at 2 Mb/s ;-).
- *
- *	I have also looked into disabling only our interrupt on the card
- *	(via HACR) instead of all interrupts in the processor (via cli),
- *	so that other driver are not impacted, and it look like it's
- *	possible, but it's very tricky to do right (full of races). As
- *	the gain would be mostly for SMP systems, it can wait...
- *
- * Debugging and options
- * ---------------------
- *	You will find below a set of '#define" allowing a very fine control
- *	on the driver behaviour and the debug messages printed.
- *	The main options are :
- *	o SET_PSA_CRC, to have your card correctly recognised by
- *	  an access point and the Point-to-Point diagnostic tool.
- *	o USE_PSA_CONFIG, to read configuration from the PSA (EEprom)
- *	  (otherwise we always start afresh with some defaults)
- *
- * wavelan.o is too darned big
- * ---------------------------
- *	That's true!  There is a very simple way to reduce the driver
- *	object by 33%!  Comment out the following line:
- *		#include <linux/wireless.h>
- *	Other compile options can also reduce the size of it...
- *
- * MAC address and hardware detection:
- * -----------------------------------
- *	The detection code for the WaveLAN checks that the first three
- *	octets of the MAC address fit the company code.  This type of
- *	detection works well for AT&T cards (because the AT&T code is
- *	hardcoded in wavelan.h), but of course will fail for other
- *	manufacturers.
- *
- *	If you are sure that your card is derived from the WaveLAN,
- *	here is the way to configure it:
- *	1) Get your MAC address
- *		a) With your card utilities (wfreqsel, instconf, etc.)
- *		b) With the driver:
- *			o compile the kernel with DEBUG_CONFIG_INFO enabled
- *			o Boot and look the card messages
- *	2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan.h)
- *	3) Compile and verify
- *	4) Send me the MAC code.  I will include it in the next version.
- *

-
-/* --------------------- WIRELESS EXTENSIONS --------------------- */
-/*
- * This driver is the first to support "wireless extensions".
- * This set of extensions provides a standard way to control the wireless
- * characteristics of the hardware.  Applications such as mobile IP may
- * take advantage of it.
- *
- * It might be a good idea as well to fetch the wireless tools to
- * configure the device and play a bit.

-/* --------------------------- HISTORY --------------------------- */
-/*
- * This is based on information in the drivers' headers. It may not be
- * accurate, and I guarantee only my best effort.
- *
- * The history of the WaveLAN drivers is as complicated as the history of
- * the WaveLAN itself (NCR -> AT&T -> Lucent).
- *
- * It all started with Anders Klemets <klemets@paul.rutgers.edu>
- * writing a WaveLAN ISA driver for the Mach microkernel.  Girish
- * Welling <welling@paul.rutgers.edu> had also worked on it.
- * Keith Moore modified this for the PCMCIA hardware.
- * 
- * Robert Morris <rtm@das.harvard.edu> ported these two drivers to BSDI
- * and added specific PCMCIA support (there is currently no equivalent
- * of the PCMCIA package under BSD).
- *
- * Jim Binkley <jrb@cs.pdx.edu> ported both BSDI drivers to FreeBSD.
- *
- * Bruce Janson <bruce@cs.usyd.edu.au> ported the BSDI ISA driver to Linux.
- *
- * Anthony D. Joseph <adj@lcs.mit.edu> started to modify Bruce's driver
- * (with help of the BSDI PCMCIA driver) for PCMCIA.
- * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished this work.
- * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
- * 2.00 cards correctly (2.4 GHz with frequency selection).
- * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
- * PCMCIA package (and bug corrections).
- *
- * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
- * patches to the PCMCIA driver.  Later, I added code in the ISA driver
- * for Wireless Extensions and full support of frequency selection
- * cards.  Then, I did the same to the PCMCIA driver, and did some
- * reorganisation.  Finally, I came back to the ISA driver to
- * upgrade it at the same level as the PCMCIA one and reorganise
- * the code.
- * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
- * much needed information on the WaveLAN hardware.

-/* ------------------------- IMPROVEMENTS ------------------------- */
-/*
- * I proudly present:
- *
- * Changes made in first pre-release:
- * ----------------------------------
- *	- reorganisation of the code, function name change
- *	- creation of private header (wavelan.p.h)
- *	- reorganised debug messages
- *	- more comments, history, etc.
- *	- mmc_init:  configure the PSA if not done
- *	- mmc_init:  correct default value of level threshold for PCMCIA
- *	- mmc_init:  2.00 detection better code for 2.00 initialization
- *	- better info at startup
- *	- IRQ setting (note:  this setting is permanent)
- *	- watchdog:  change strategy (and solve module removal problems)
- *	- add wireless extensions (ioctl and get_wireless_stats)
- *	  get/set nwid/frequency on fly, info for /proc/net/wireless
- *	- more wireless extensions:  SETSPY and GETSPY
- *	- make wireless extensions optional
- *	- private ioctl to set/get quality and level threshold, histogram
- *	- remove /proc/net/wavelan
- *	- suppress useless stuff from lp (net_local)
- *	- kernel 2.1 support (copy_to/from_user instead of memcpy_to/fromfs)
- *	- add message level (debug stuff in /var/adm/debug and errors not
- *	  displayed at console and still in /var/adm/messages)
- *	- multi device support
- *	- start fixing the probe (init code)
- *	- more inlines
- *	- man page
- *	- many other minor details and cleanups
- *
- * Changes made in second pre-release:
- * -----------------------------------
- *	- clean up init code (probe and module init)
- *	- better multiple device support (module)
- *	- name assignment (module)
- *
- * Changes made in third pre-release:
- * ----------------------------------
- *	- be more conservative on timers
- *	- preliminary support for multicast (I still lack some details)
- *
- * Changes made in fourth pre-release:
- * -----------------------------------
- *	- multicast (revisited and finished)
- *	- avoid reset in set_multicast_list (a really big hack)
- *	  if somebody could apply this code for other i82586 based drivers
- *	- share onboard memory 75% RU and 25% CU (instead of 50/50)
- *
- * Changes made for release in 2.1.15:
- * -----------------------------------
- *	- change the detection code for multi manufacturer code support
- *
- * Changes made for release in 2.1.17:
- * -----------------------------------
- *	- update to wireless extensions changes
- *	- silly bug in card initial configuration (psa_conf_status)
- *
- * Changes made for release in 2.1.27 & 2.0.30:
- * --------------------------------------------
- *	- small bug in debug code (probably not the last one...)
- *	- remove extern keyword for wavelan_probe()
- *	- level threshold is now a standard wireless extension (version 4 !)
- *	- modules parameters types (new module interface)
- *
- * Changes made for release in 2.1.36:
- * -----------------------------------
- *	- byte count stats (courtesy of David Hinds)
- *	- remove dev_tint stuff (courtesy of David Hinds)
- *	- encryption setting from Brent Elphick (thanks a lot!)
- *	- 'ioaddr' to 'u_long' for the Alpha (thanks to Stanislav Sinyagin)
- *
- * Other changes (not by me) :
- * -------------------------
- *	- Spelling and gramar "rectification".
- *
- * Changes made for release in 2.0.37 & 2.2.2 :
- * ------------------------------------------
- *	- Correct status in /proc/net/wireless
- *	- Set PSA CRC to make PtP diagnostic tool happy (Bob Gray)
- *	- Module init code don't fail if we found at least one card in
- *	  the address list (Karlis Peisenieks)
- *	- Missing parenthesis (Christopher Peterson)
- *	- Correct i82586 configuration parameters
- *	- Encryption initialisation bug (Robert McCormack)
- *	- New mac addresses detected in the probe
- *	- Increase watchdog for busy environments
- *
- * Changes made for release in 2.0.38 & 2.2.7 :
- * ------------------------------------------
- *	- Correct the reception logic to better report errors and avoid
- *	  sending bogus packet up the stack
- *	- Delay RU config to avoid corrupting first received packet
- *	- Change config completion code (to actually check something)
- *	- Avoid reading out of bound in skbuf to transmit
- *	- Rectify a lot of (useless) debugging code
- *	- Change the way to `#ifdef SET_PSA_CRC'
- *
- * Changes made for release in 2.2.11 & 2.3.13 :
- * -------------------------------------------
- *	- Change e-mail and web page addresses
- *	- Watchdog timer is now correctly expressed in HZ, not in jiffies
- *	- Add channel number to the list of frequencies in range
- *	- Add the (short) list of bit-rates in range
- *	- Developp a new sensitivity... (sens.value & sens.fixed)
- *
- * Changes made for release in 2.2.14 & 2.3.23 :
- * -------------------------------------------
- *	- Fix check for root permission (break instead of exit)
- *	- New nwid & encoding setting (Wireless Extension 9)
- *
- * Changes made for release in 2.3.49 :
- * ----------------------------------
- *	- Indentation reformating (Alan)
- *	- Update to new network API (softnet - 2.3.43) :
- *		o replace dev->tbusy (Alan)
- *		o replace dev->tstart (Alan)
- *		o remove dev->interrupt (Alan)
- *		o add SMP locking via spinlock in splxx (me)
- *		o add spinlock in interrupt handler (me)
- *		o use kernel watchdog instead of ours (me)
- *		o increase watchdog timeout (kernel is more sensitive) (me)
- *		o verify that all the changes make sense and work (me)
- *	- Fixup a potential gotcha when reconfiguring and thighten a bit
- *		the interactions with Tx queue.
- *
- * Changes made for release in 2.4.0 :
- * ---------------------------------
- *	- Fix spinlock stupid bugs that I left in. The driver is now SMP
- *		compliant and doesn't lockup at startup.
- *
- * Changes made for release in 2.5.2 :
- * ---------------------------------
- *	- Use new driver API for Wireless Extensions :
- *		o got rid of wavelan_ioctl()
- *		o use a bunch of iw_handler instead
- *
- * Changes made for release in 2.5.35 :
- * ----------------------------------
- *	- Set dev->trans_start to avoid filling the logs
- *	- Handle better spurious/bogus interrupt
- *	- Avoid deadlocks in mmc_out()/mmc_in()
- *
- * Wishes & dreams:
- * ----------------
- *	- roaming (see Pcmcia driver)

-/*
- * This driver provide a Linux interface to the Wavelan Pcmcia hardware
- * The Wavelan is a product of Lucent (http://www.wavelan.com/).
- * This division was formerly part of NCR and then AT&T.
- * Wavelan are also distributed by DEC (RoamAbout DS)...
- *
- * To know how to use this driver, read the PCMCIA HOWTO.
- * If you want to exploit the many other fonctionalities, look comments
- * in the code...
- *
- * This driver is the result of the effort of many peoples (see below).
- */
-
-/* ------------------------ SPECIFIC NOTES ------------------------ */
-/*
- * Web page
- * --------
- *	I try to maintain a web page with the Wireless LAN Howto at :
- *	    http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html
- *
- * SMP
- * ---
- *	We now are SMP compliant (I eventually fixed the remaining bugs).
- *	The driver has been tested on a dual P6-150 and survived my usual
- *	set of torture tests.
- *	Anyway, I spent enough time chasing interrupt re-entrancy during
- *	errors or reconfigure, and I designed the locked/unlocked sections
- *	of the driver with great care, and with the recent addition of
- *	the spinlock (thanks to the new API), we should be quite close to
- *	the truth.
- *	The SMP/IRQ locking is quite coarse and conservative (i.e. not fast),
- *	but better safe than sorry (especially at 2 Mb/s ;-).
- *
- *	I have also looked into disabling only our interrupt on the card
- *	(via HACR) instead of all interrupts in the processor (via cli),
- *	so that other driver are not impacted, and it look like it's
- *	possible, but it's very tricky to do right (full of races). As
- *	the gain would be mostly for SMP systems, it can wait...
- *
- * Debugging and options
- * ---------------------
- *	You will find below a set of '#define" allowing a very fine control
- *	on the driver behaviour and the debug messages printed.
- *	The main options are :
- *	o WAVELAN_ROAMING, for the experimental roaming support.
- *	o SET_PSA_CRC, to have your card correctly recognised by
- *	  an access point and the Point-to-Point diagnostic tool.
- *	o USE_PSA_CONFIG, to read configuration from the PSA (EEprom)
- *	  (otherwise we always start afresh with some defaults)
- *
- * wavelan_cs.o is darn too big
- * -------------------------
- *	That's true ! There is a very simple way to reduce the driver
- *	object by 33% (yes !). Comment out the following line :
- *		#include <linux/wireless.h>
- *	Other compile options can also reduce the size of it...
- *
- * MAC address and hardware detection :
- * ----------------------------------
- *	The detection code of the wavelan chech that the first 3
- *	octets of the MAC address fit the company code. This type of
- *	detection work well for AT&T cards (because the AT&T code is
- *	hardcoded in wavelan_cs.h), but of course will fail for other
- *	manufacturer.
- *
- *	If you are sure that your card is derived from the wavelan,
- *	here is the way to configure it :
- *	1) Get your MAC address
- *		a) With your card utilities (wfreqsel, instconf, ...)
- *		b) With the driver :
- *			o compile the kernel with DEBUG_CONFIG_INFO enabled
- *			o Boot and look the card messages
- *	2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan_cs.h)
- *	3) Compile & verify
- *	4) Send me the MAC code - I will include it in the next version...
- *
- */
-
-/* --------------------- WIRELESS EXTENSIONS --------------------- */
-/*
- * This driver is the first one to support "wireless extensions".
- * This set of extensions provide you some way to control the wireless
- * caracteristics of the hardware in a standard way and support for
- * applications for taking advantage of it (like Mobile IP).
- *
- * It might be a good idea as well to fetch the wireless tools to
- * configure the device and play a bit.

-/* --------------------------- HISTORY --------------------------- */
-/*
- * The history of the Wavelan drivers is as complicated as history of
- * the Wavelan itself (NCR -> AT&T -> Lucent).
- *
- * All started with Anders Klemets <klemets@paul.rutgers.edu>,
- * writing a Wavelan ISA driver for the MACH microkernel. Girish
- * Welling <welling@paul.rutgers.edu> had also worked on it.
- * Keith Moore modify this for the Pcmcia hardware.
- * 
- * Robert Morris <rtm@das.harvard.edu> port these two drivers to BSDI
- * and add specific Pcmcia support (there is currently no equivalent
- * of the PCMCIA package under BSD...).
- *
- * Jim Binkley <jrb@cs.pdx.edu> port both BSDI drivers to FreeBSD.
- *
- * Bruce Janson <bruce@cs.usyd.edu.au> port the BSDI ISA driver to Linux.
- *
- * Anthony D. Joseph <adj@lcs.mit.edu> started modify Bruce driver
- * (with help of the BSDI PCMCIA driver) for PCMCIA.
- * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished is work.
- * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
- * correctly 2.00 cards (2.4 GHz with frequency selection).
- * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
- * Pcmcia package (+ bug corrections).
- *
- * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
- * patchs to the Pcmcia driver. After, I added code in the ISA driver
- * for Wireless Extensions and full support of frequency selection
- * cards. Now, I'm doing the same to the Pcmcia driver + some
- * reorganisation.
- * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
- * much needed informations on the Wavelan hardware.
