+ * 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.

+ * use again, in our shadow copy.
+ *
+ * It's up to the caller to free the tids when they are done.
+ * We'll unlock the pages as they free them.

- 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.

-TODO:
- - 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>.

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.

-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
-# echo "" > /proc/net/batman-adv/interfaces

+ * How to be a proc read function
+ * ------------------------------

+ *
+ * Assume that the buffer is "count" bytes in size.
+ *
+ * If you know you have supplied all the data you
+ * have, set *peof.
+ *
+ * You have three ways to return data:
+ * 0) Leave *start = NULL. (This is the default.)
+ * Put the data of the requested offset at that
+ * offset within the buffer. Return the number (n)
+ * of bytes there are from the beginning of the
+ * buffer up to the last byte of data. If the
+ * number of supplied bytes (= n - offset) is
+ * greater than zero and you didn't signal eof
+ * and the reader is prepared to take more data
+ * you will be called again with the requested
+ * offset advanced by the number of bytes
+ * absorbed. This interface is useful for files
+ * no larger than the buffer.
+ * 1) Set *start = an unsigned long value less than
+ * the buffer address but greater than zero.
+ * Put the data of the requested offset at the
+ * beginning of the buffer. Return the number of
+ * bytes of data placed there. If this number is
+ * greater than zero and you didn't signal eof
+ * and the reader is prepared to take more data
+ * you will be called again with the requested
+ * offset advanced by *start. This interface is
+ * useful when you have a large file consisting
+ * of a series of blocks which you want to count
+ * and return as wholes.
+ * (Hack by Paul.Russell@rustcorp.com.au)
+ * 2) Set *start = an address within the buffer.
+ * Put the data of the requested offset at *start.
+ * Return the number of bytes of data placed there.
+ * If this number is greater than zero and you
+ * didn't signal eof and the reader is prepared to
+ * take more data you will be called again with the
+ * requested offset advanced by the number of bytes

+Description:
+ Some devices have internal clocks. This parameter sets the
+ resulting sampling frequency. In many devices this
+ parameter has an effect on input filters etc rather than
+ 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.

+Description:
+ If known for a device, offset to be added to in[m]_raw prior
+ to scaling by in[_name][m]_scale in order to obtain voltage in
+ millivolts. Not present if the offset is always 0 or unknown.
+ If m is not present, then voltage offset applies to all in
+ channels. May be writable if a variable offset is controlled
+ by the device. Note that this is different to calibbias which
+ is for devices that apply offsets to compensate for variation
+ between different instances of the part, typically adjusted by
+ using some hardware supported calibration procedure.

+ ---help---
+ This driver provides a memory management interface to
+ restricted access regions (RAR) available on the Intel
+ Moorestown platform.
+
+ Once locked down, restricted access regions are only
+ accessible by specific hardware on the platform. The x86
+ CPU is typically not one of those platforms. As such this
+ driver does not access RAR, and only provides a buffer
+ allocation/bookkeeping mechanism.
+
+ If unsure, say N.

+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

+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.

-/*********************************************************************
- *
- * Filename: netwave_cs.c
- * Version: 0.4.1
- * Description: Netwave AirSurfer Wireless LAN PC Card driver
- * Status: Experimental.
- * Authors: John Markus Bjørndalen <johnm@cs.uit.no>
- * Dag Brattli <dagb@cs.uit.no>
- * David Hinds <dahinds@users.sourceforge.net>
- * Created at: A long time ago!
- * Modified at: Mon Nov 10 11:54:37 1997
- * Modified by: Dag Brattli <dagb@cs.uit.no>
- *
- * Copyright (c) 1997 University of Tromsø, Norway
- *
- * 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)

- - handle device unplug case
- - handle temperature above threshold
- - use bus address instead of physical address for DMA

- 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.

- * 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>.

- The Lucent WaveLAN (formerly NCR and AT&T; or DEC RoamAbout DS) is
- a Radio LAN (wireless Ethernet-like Local Area Network) using the
- radio frequencies 900 MHz and 2.4 GHz.
-
- If you want to use an ISA WaveLAN card under Linux, say Y and read
- the Ethernet-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>. Some more specific
- information is contained in
- <file:Documentation/networking/wavelan.txt> and in the source code
- <file:drivers/net/wireless/wavelan.p.h>.
-
- You will also need the wireless tools package available from
- <http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
- Please read the man pages contained therein.
-
- To compile this driver as a module, choose M here: the module will be
- called wavelan.

- driver is for the non-IEEE-802.11 Wavelan cards.
-
- To compile this driver as a module, choose M here: the module will be

-/************************** DOCUMENTATION ***************************/
-/*
- * 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.

- * and want their original copyright to remain somewhere in the
- * code (for myself, I go with the GPL).

- *
- * 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...

- * 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.

+ * On 310/325, there are three queue modes available which
+ * are chosen by setting bits 7:5 in SR26:
+ * 1. MMIO queue mode (bit 5, 0x20). The hardware will keep
+ * track of the queue, the FIFO, command parsing and so
+ * on. This is the one comparable to the 300 series.
+ * 2. VRAM queue mode (bit 6, 0x40). In this case, one will
+ * have to do queue management himself. Register 0x85c4 will
+ * hold the location of the next free queue slot, 0x85c8
+ * is the "queue read pointer" whose way of working is
+ * unknown to me. Anyway, this mode would require a
+ * translation of the MMIO commands to some kind of
+ * accelerator assembly and writing these commands
+ * to the memory location pointed to by 0x85c4.
+ * We will not use this, as nobody knows how this
+ * "assembly" works, and as it would require a complete
+ * re-write of the accelerator code.
+ * 3. AGP queue mode (bit 7, 0x80). Works as 2., but keeps the
+ * queue in AGP memory space.
+ *
+ * SR26 bit 4 is called "Bypass H/W queue".
+ * SR26 bit 1 is called "Enable Command Queue Auto Correction"
+ * SR26 bit 0 resets the queue
+ * Size of queue memory is encoded in bits 3:2 like this:
+ * 00 (0x00) 512K
+ * 01 (0x04) 1M
+ * 10 (0x08) 2M
+ * 11 (0x0C) 4M
+ * The queue location is to be written to 0x85C0.
