+Block io priorities
+===================
+
+
+Intro
+-----
+
+With the introduction of cfq v3 (aka cfq-ts or time sliced cfq), basic io
+priorities is supported for reads on files. This enables users to io nice
+processes or process groups, similar to what has been possible to cpu
+scheduling for ages. This document mainly details the current possibilites
+with cfq, other io schedulers do not support io priorities so far.
+
+Scheduling classes
+------------------
+
+CFQ implements three generic scheduling classes that determine how io is
+served for a process.
+
+IOPRIO_CLASS_RT: This is the realtime io class. This scheduling class is given
+higher priority than any other in the system, processes from this class are
+given first access to the disk every time. Thus it needs to be used with some
+care, one io RT process can starve the entire system. Within the RT class,
+there are 8 levels of class data that determine exactly how much time this
+process needs the disk for on each service. In the future this might change
+to be more directly mappable to performance, by passing in a wanted data
+rate instead.
+
+IOPRIO_CLASS_BE: This is the best-effort scheduling class, which is the default
+for any process that hasn't set a specific io priority. The class data
+determines how much io bandwidth the process will get, it's directly mappable
+to the cpu nice levels just more coarsely implemented. 0 is the highest
+BE prio level, 7 is the lowest. The mapping between cpu nice level and io
+nice level is determined as: io_nice = (cpu_nice + 20) / 5.
+
+IOPRIO_CLASS_IDLE: This is the idle scheduling class, processes running at this
+level only get io time when no one else needs the disk. The idle class has no
+class data, since it doesn't really apply here.
+
+Tools
+-----
+
+See below for a sample ionice tool. Usage:
+
+# ionice -c<class> -n<level> -p<pid>
+
+If pid isn't given, the current process is assumed. IO priority settings
+are inherited on fork, so you can use ionice to start the process at a given
+level:
+
+# ionice -c2 -n0 /bin/ls
+
+will run ls at the best-effort scheduling class at the highest priority.
+For a running process, you can give the pid instead:
+
+# ionice -c1 -n2 -p100
+
+will change pid 100 to run at the realtime scheduling class, at priority 2.

+Then you may have to modify the default routing table with command :
+
+ route add default eth0
- B. The following steps teach you how to activate a DM9102 board:
-
- 1. Used the upper compiler command to compile dmfe.c
-
- 2. Insert dmfe module into kernel
- "insmod dmfe" ;;Auto Detection Mode (Suggest)
- "insmod dmfe mode=0" ;;Force 10M Half Duplex
- "insmod dmfe mode=1" ;;Force 100M Half Duplex
- "insmod dmfe mode=4" ;;Force 10M Full Duplex
- "insmod dmfe mode=5" ;;Force 100M Full Duplex
-
- 3. Config a dm9102 network interface
- "ifconfig eth0 172.22.3.18"
- ^^^^^^^^^^^ Your IP address
-
- 4. Activate the IP routing table. For some distributions, it is not
- necessary. You can type "route" to check.
-
- "route add default eth0"
+Now your ethernet card should be up and running.
- 5. Well done. Your DM9102 adapter is now activated.
+TODO:
+
+Implement pci_driver::suspend() and pci_driver::resume() power management methods.
+Check on 64 bit boxes.
+Check and fix on big endian boxes.
+Test and make sure PCI latency is now correct for all cases.
- C. Object files description:

+Matching of PCMCIA devices to drivers is done using one or more of the
+following criteria:
+
+- manufactor ID
+- card ID
+- product ID strings _and_ hashes of these strings
+- function ID
+- device function (actual and pseudo)
+
+You should use the helpers in include/pcmcia/device_id.h for generating the
+struct pcmcia_device_id[] entries which match devices to drivers.
+
+If you want to match product ID strings, you also need to pass the crc32
+hashes of the string to the macro, e.g. if you want to match the product ID
+string 1, you need to use
+
+PCMCIA_DEVICE_PROD_ID1("some_string", 0x(hash_of_some_string)),
+
+If the hash is incorrect, the kernel will inform you about this in "dmesg"
+upon module initialization, and tell you of the correct hash.
+
+You can determine the hash of the product ID strings by running
+"pcmcia-modalias %n.%m" [%n being replaced with the socket number and %m being
+replaced with the device function] from pcmciautils. It generates a string
+in the following form:
+pcmcia:m0149cC1ABf06pfn00fn00pa725B842DpbF1EFEE84pc0877B627pd00000000
+
+The hex value after "pa" is the hash of product ID string 1, after "pb" for
+string 2 and so on.
+
+Alternatively, you can use this small tool to determine the crc32 hash.
+simply pass the string you want to evaluate as argument to this program,
+e.g.
+$ ./crc32hash "Dual Speed"
+
+-------------------------------------------------------------------------
+/* crc32hash.c - derived from linux/lib/crc32.c, GNU GPL v2 */
+#include <string.h>
+#include <stdio.h>
+#include <ctype.h>
+#include <stdlib.h>
+
+unsigned int crc32(unsigned char const *p, unsigned int len)
+{
+ int i;
+ unsigned int crc = 0;
+ while (len--) {
+ crc ^= *p++;
+ for (i = 0; i < 8; i++)
+ crc = (crc >> 1) ^ ((crc & 1) ? 0xedb88320 : 0);
+ }
+ return crc;
+}
+
+int main(int argc, char **argv) {

+This file details changes in 2.6 which affect PCMCIA card driver authors:
+
+* in-kernel device<->driver matching
+ PCMCIA devices and their correct drivers can now be matched in
+ kernelspace. See 'devicetable.txt' for details.
+
+* Device model integration (as of 2.6.11)
+ A struct pcmcia_device is registered with the device model core,
+ and can be used (e.g. for SET_NETDEV_DEV) by using
+ handle_to_dev(client_handle_t * handle).
+
+* Convert internal I/O port addresses to unsigned long (as of 2.6.11)
+ ioaddr_t should be replaced by kio_addr_t in PCMCIA card drivers.
+
+* irq_mask and irq_list parameters (as of 2.6.11)
+ The irq_mask and irq_list parameters should no longer be used in
+ PCMCIA card drivers. Instead, it is the job of the PCMCIA core to
+ determine which IRQ should be used. Therefore, link->irq.IRQInfo2
+ is ignored.
+
+* client->PendingEvents is gone (as of 2.6.11)
+ client->PendingEvents is no longer available.
+
+* client->Attributes are gone (as of 2.6.11)
+ client->Attributes is unused, therefore it is removed from all
+ PCMCIA card drivers
+
+* core functions no longer available (as of 2.6.11)
+ The following functions have been removed from the kernel source
+ because they are unused by all in-kernel drivers, and no external
+ driver was reported to rely on them:
+ pcmcia_get_first_region()
+ pcmcia_get_next_region()
+ pcmcia_modify_window()
+ pcmcia_set_event_mask()
+ pcmcia_get_first_window()
+ pcmcia_get_next_window()
+
+* device list iteration upon module removal (as of 2.6.10)
+ It is no longer necessary to iterate on the driver's internal
+ client list and call the ->detach() function upon module removal.
+
+* Resource management. (as of 2.6.8)
+ Although the PCMCIA subsystem will allocate resources for cards,
+ it no longer marks these resources busy. This means that driver
+ authors are now responsible for claiming your resources as per
+ other drivers in Linux. You should use request_region() to mark
+ your IO regions in-use, and request_mem_region() to mark your
+ memory regions in-use. The name argument should be a pointer to
+ your driver name. Eg, for pcnet_cs, name should point to the
+ string "pcnet_cs".

-Video4Linux provides the following sets of device files. These live on the

-Video4Linux programs open and scan the devices to find what they are looking
-for. Capability queries define what each interface supports. The
-described API is only defined for video capture cards. The relevant subset
-applies to radio cards. Teletext interfaces talk the existing VTX API.
-<P>
-<H3>Capability Query Ioctl</H3>
-The <B>VIDIOCGCAP</B> ioctl call is used to obtain the capability
-information for a video device. The <b>struct video_capability</b> object
-passed to the ioctl is completed and returned. It contains the following
-information
-<P>
-<TABLE>

-<P>
-The type field lists the capability flags for the device. These are
-as follows
-<P>
-<TABLE>
-<TR><TH>Name</TH><TH>Description</TH>
-<TR><TD><b>VID_TYPE_CAPTURE</b><TD>Can capture to memory</TD>
-<TR><TD><b>VID_TYPE_TUNER</b><TD>Has a tuner of some form</TD>

-</TABLE>
-<P>
-The minimum and maximum sizes listed for a capture device do not imply all
-that all height/width ratios or sizes within the range are possible. A
-request to set a size will be honoured by the largest available capture
-size whose capture is no large than the requested rectangle in either
-direction. For example the quickcam has 3 fixed settings.
-<P>
-<H3>Frame Buffer</H3>
-Capture cards that drop data directly onto the frame buffer must be told the
-base address of the frame buffer, its size and organisation. This is a
-privileged ioctl and one that eventually X itself should set.
-<P>
-The <b>VIDIOCSFBUF</b> ioctl sets the frame buffer parameters for a capture
-card. If the card does not do direct writes to the frame buffer then this
-ioctl will be unsupported. The <b>VIDIOCGFBUF</b> ioctl returns the
-currently used parameters. The structure used in both cases is a
-<b>struct video_buffer</b>.

-<TR><TD><b>int bytesperline</b></TD><TD>Number of bytes of memory between the start of two adjacent lines</TD>
-</TABLE>
-<P>
-Note that these values reflect the physical layout of the frame buffer.
-The visible area may be smaller. In fact under XFree86 this is commonly the
-case. XFree86 DGA can provide the parameters required to set up this ioctl.
-Setting the base address to NULL indicates there is no physical frame buffer
-access.
-<P>
-<H3>Capture Windows</H3>
-The capture area is described by a <b>struct video_window</b>. This defines
-a capture area and the clipping information if relevant. The
-<b>VIDIOCGWIN</b> ioctl recovers the current settings and the
-<b>VIDIOCSWIN</b> sets new values. A successful call to <b>VIDIOCSWIN</b>
-indicates that a suitable set of parameters have been chosen. They do not
-indicate that exactly what was requested was granted. The program should
-call <b>VIDIOCGWIN</b> to check if the nearest match was suitable. The
-<b>struct video_window</b> contains the following fields.

-<TR><TD><b>height</b></TD><TD>Height of rectangle to skip</TD>
-</TABLE>
-<P>
-Merely setting the window does not enable capturing. Overlay capturing
-(i.e. PCI-PCI transfer to the frame buffer of the video card)
-is activated by passing the <b>VIDIOCCAPTURE</b> ioctl a value of 1, and
-disabled by passing it a value of 0.
-<P>
-Some capture devices can capture a subfield of the image they actually see.
-This is indicated when VIDEO_TYPE_SUBCAPTURE is defined.

-the <b>struct video_channel</b> is filled in with information about the
-nature of the channel itself.
-<P>
-The <b>VIDIOCSCHAN</b> ioctl takes an integer argument and switches the
-capture to this input. It is not defined whether parameters such as colour
-settings or tuning are maintained across a channel switch. The caller should

-Once the mmap has been made the VIDIOCMCAPTURE ioctl starts the
-capture to a frame using the format and image size specified in the
-video_mmap (which should match or be below the initial query size).
-When the VIDIOCMCAPTURE ioctl returns the frame is <em>not</em>
-captured yet, the driver just instructed the hardware to start the
-capture. The application has to use the VIDIOCSYNC ioctl to wait
-until the capture of a frame is finished. VIDIOCSYNC takes the frame
-number you want to wait for as argument.
-<p>
-It is allowed to call VIDIOCMCAPTURE multiple times (with different
-frame numbers in video_mmap->frame of course) and thus have multiple
-outstanding capture requests. A simple way do to double-buffering
-using this feature looks like this:
-<pre>
-/* setup everything */
-VIDIOCMCAPTURE(0)
-while (whatever) {
- VIDIOCMCAPTURE(1)
- VIDIOCSYNC(0)
- /* process frame 0 while the hardware captures frame 1 */
- VIDIOCMCAPTURE(0)
- VIDIOCSYNC(1)
- /* process frame 1 while the hardware captures frame 0 */
-}
-</pre>
-Note that you are <em>not</em> limited to only two frames. The API
-allows up to 32 frames, the VIDIOCGMBUF ioctl returns the number of
-frames the driver granted. Thus it is possible to build deeper queues
-to avoid loosing frames on load peaks.
-<p>
-While capturing to memory the driver will make a "best effort" attempt
-to capture to screen as well if requested. This normally means all
-frames that "miss" memory mapped capture will go to the display.
-<P>
-A final ioctl exists to allow a device to obtain related devices if a
-driver has multiple components (for example video0 may not be associated
-with vbi0 which would cause an intercast display program to make a bad
-mistake). The VIDIOCGUNIT ioctl reports the unit numbers of the associated
-devices if any exist. The video_unit structure has the following fields.

source "drivers/Kconfig"
-config PRINTER
- tristate "Parallel printer support"
- depends on PARPORT
- ---help---
- If you intend to attach a printer to the parallel port of your Linux
- box (as opposed to using a serial printer; if the connector at the
- printer has 9 or 25 holes ["female"], then it's serial), say Y.
- Also read the Printing-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>.
-
- It is possible to share one parallel port among several devices
- (e.g. printer and ZIP drive) and it is safe to compile the
- corresponding drivers into the kernel. If you want to compile this
- driver as a module however, choose M here and read
- <file:Documentation/parport.txt>. The module will be called lp.
-
- If you have several parallel ports, you can specify which ports to
- use with the "lp" kernel command line option. (Try "man bootparam"
- or see the documentation of your boot loader (silo) about how to pass
- options to the kernel at boot time.) The syntax of the "lp" command
- line option can be found in <file:drivers/char/lp.c>.
-
- If you have more than 8 printers, you need to increase the LP_NO
- macro in lp.c and the PARPORT_MAX macro in parport.h.

+ *
+ * Copyright (C) 2004 Red Hat <alan@redhat.com>
+ *
+ * May be copied or modified under the terms of the GNU General Public License
+ * Based in part on the ITE vendor provided SCSI driver.
+ *
+ * Documentation available from
+ * http://www.ite.com.tw/pc/IT8212F_V04.pdf
+ * Some other documents are NDA.
+ *
+ * The ITE8212 isn't exactly a standard IDE controller. It has two
+ * modes. In pass through mode then it is an IDE controller. In its smart
+ * mode its actually quite a capable hardware raid controller disguised
+ * as an IDE controller. Smart mode only understands DMA read/write and
+ * identify, none of the fancier commands apply. The IT8211 is identical
+ * in other respects but lacks the raid mode.
+ *
+ * Errata:
+ * o Rev 0x10 also requires master/slave hold the same DMA timings and
+ * cannot do ATAPI MWDMA.
+ * o The identify data for raid volumes lacks CHS info (technically ok)
+ * but also fails to set the LBA28 and other bits. We fix these in
+ * the IDE probe quirk code.
+ * o If you write LBA48 sized I/O's (ie > 256 sector) in smart mode
+ * raid then the controller firmware dies
+ * o Smart mode without RAID doesn't clear all the necessary identify
+ * bits to reduce the command set to the one used
+ *
+ * This has a few impacts on the driver
+ * - In pass through mode we do all the work you would expect
+ * - In smart mode the clocking set up is done by the controller generally
+ * but we must watch the other limits and filter.
+ * - There are a few extra vendor commands that actually talk to the
+ * controller but only work PIO with no IRQ.
+ *
+ * Vendor areas of the identify block in smart mode are used for the
+ * timing and policy set up. Each HDD in raid mode also has a serial
+ * block on the disk. The hardware extra commands are get/set chip status,
+ * rebuild, get rebuild status.
+ *
+ * In Linux the driver supports pass through mode as if the device was
+ * just another IDE controller. If the smart mode is running then
+ * volumes are managed by the controller firmware and each IDE "disk"
+ * is a raid volume. Even more cute - the controller can do automated
+ * hotplug and rebuild.
+ *
+ * The pass through controller itself is a little demented. It has a
+ * flaw that it has a single set of PIO/MWDMA timings per channel so
+ * non UDMA devices restrict each others performance. It also has a
+ * single clock source per channel so mixed UDMA100/133 performance
+ * isn't perfect and we have to pick a clock. Thankfully none of this
+ * matters in smart mode. ATAPI DMA is not currently supported.
+ *
+ * It seems the smart mode is a win for RAID1/RAID10 but otherwise not.
+ *
+ * TODO
+ * - ATAPI UDMA is ok but not MWDMA it seems
+ * - RAID configuration ioctls
+ * - Move to libata once it grows up

- * The following sequence prevents a problem that is seen with O'Hare ASICs
- * (most versions -- also with some Heathrow and Hydra ASICs) where a zero

- * This problem can occur as a result of a zero bit at the receiver input

- * The SCC is initialized (hardware or software).
- * A framing error is detected.
- * The clocking option changes from synchronous or X1 asynchronous
- * clocking to X16, X32, or X64 asynchronous clocking.
- * The decoding mode is changed among NRZ, NRZI, FM0, or FM1.

- the RTL8139 chips. If you have one of those, say Y and read
- the Ethernet-HOWTO <http://www.tldp.org/docs.html#howto>.
+ the RTL 8129/8130/8139 chips. If you have one of those, say Y and
+ read the Ethernet-HOWTO <http://www.tldp.org/docs.html#howto>.
To compile this driver as a module, choose M here: the module
will be called 8139too. This is recommended.

- * o Added some module metadata
- *
- * v0.06e -> v0.06f - 14/8/2001 - David Gibson

- *
- * v0.07a -> v0.08 - 3/10/2001 - David Gibson
- * o Fixed a possible buffer overrun found by the Stanford checker (in
- * dldwd_ioctl_setiwencode()). Can only be called by root anyway, so not
- * a big problem.
- * o Turned has_big_wep on for Intersil cards. That's not true for all of
- * them but we should at least let the capable ones try.
- * o Wait for BUSY to clear at the beginning of hermes_bap_seek(). I
- * realized that my assumption that the driver's serialization
- * would prevent the BAP being busy on entry was possibly false, because
- * things other than seeks may make the BAP busy.
- * o Use "alternate" (oui 00:00:00) encapsulation by default.
- * Setting use_old_encaps will mimic the old behaviour, but I think we
- * will be able to eliminate this.
- * o Don't try to make __initdata const (the version string). This can't
- * work because of the way the __initdata sectioning works.
- * o Added MODULE_LICENSE tags.
- * o Support for PLX (transparent PCMCIA->PCI bridge) cards.
- * o Changed to using the new type-fascist min/max.
- *
- * v0.08 -> v0.08a - 9/10/2001 - David Gibson
- * o Inserted some missing acknowledgements/info into the Changelog.
- * o Fixed some bugs in the normalization of signal level reporting.
- * o Fixed bad bug in WEP key handling on Intersil and Symbol firmware,
- * which led to an instant crash on big-endian machines.
- *
- * v0.08a -> v0.08b - 20/11/2001 - David Gibson
- * o Lots of cleanup and bugfixes in orinoco_plx.c
- * o Cleanup to handling of Tx rate setting.
- * o Removed support for old encapsulation method.
- * o Removed old "dldwd" names.
- * o Split RID constants into a new file hermes_rid.h
- * o Renamed RID constants to match linux-wlan-ng and prism2.o
- * o Bugfixes in hermes.c
- * o Poke the PLX's INTCSR register, so it actually starts
- * generating interrupts. These cards might actually work now.
- * o Update to wireless extensions v12 (Jean II)
- * o Support for tallies and inquire command (Jean II)
- * o Airport updates for newer PPC kernels (BenH)
- *
- * v0.08b -> v0.09 - 21/12/2001 - David Gibson
- * o Some new PCI IDs for PLX cards.
- * o Removed broken attempt to do ALLMULTI reception. Just use
- * promiscuous mode instead
- * o Preliminary work for list-AP (Jean II)
- * o Airport updates from (BenH)
- * o Eliminated racy hw_ready stuff
- * o Fixed generation of fake events in irq handler. This should
- * finally kill the EIO problems (Jean II & dgibson)
- * o Fixed breakage of bitrate set/get on Agere firmware (Jean II)
- *
- * v0.09 -> v0.09a - 2/1/2002 - David Gibson
- * o Fixed stupid mistake in multicast list handling, triggering
- * a BUG()
- *
- * v0.09a -> v0.09b - 16/1/2002 - David Gibson
- * o Fixed even stupider mistake in new interrupt handling, which
- * seriously broke things on big-endian machines.
- * o Removed a bunch of redundant includes and exports.
- * o Removed a redundant MOD_{INC,DEC}_USE_COUNT pair in airport.c
- * o Don't attempt to do hardware level multicast reception on
- * Intersil firmware, just go promisc instead.
- * o Typo fixed in hermes_issue_cmd()
- * o Eliminated WIRELESS_SPY #ifdefs
- * o Status code reported on Tx exceptions
- * o Moved netif_wake_queue() from ALLOC interrupts to TX and TXEXC
- * interrupts, which should fix the timeouts we're seeing.
- *
- * v0.09b -> v0.10 - 25 Feb 2002 - David Gibson
- * o Removed nested structures used for header parsing, so the
- * driver should now work without hackery on ARM
- * o Fix for WEP handling on Intersil (Hawk Newton)
- * o Eliminated the /proc/hermes/ethXX/regs debugging file. It
- * was never very useful.
- * o Make Rx errors less noisy.
- *
- * v0.10 -> v0.11 - 5 Apr 2002 - David Gibson
- * o Laid the groundwork in hermes.[ch] for devices which map
- * into PCI memory space rather than IO space.
- * o Fixed bug in multicast handling (cleared multicast list when
- * leaving promiscuous mode).
- * o Relegated Tx error messages to debug.
- * o Cleaned up / corrected handling of allocation lengths.
- * o Set OWNSSID in IBSS mode for WinXP interoperability (jimc).
- * o Change to using alloc_etherdev() for structure allocations.
- * o Check for and drop undersized packets.
- * o Fixed a race in stopping/waking the queue. This should fix
- * the timeout problems (Pavel Roskin)
- * o Reverted to netif_wake_queue() on the ALLOC event.
- * o Fixes for recent Symbol firmwares which lack AP density
- * (Pavel Roskin).
- *
- * v0.11 -> v0.11a - 29 Apr 2002 - David Gibson
- * o Handle different register spacing, necessary for Prism 2.5
- * PCI adaptors (Steve Hill).
- * o Cleaned up initialization of card structures in orinoco_cs
- * and airport. Removed card->priv field.
- * o Make response structure optional for hermes_docmd_wait()
- * Pavel Roskin)
- * o Added PCI id for Nortel emobility to orinoco_plx.c.
- * o Cleanup to handling of Symbol's allocation bug. (Pavel Roskin)
- * o Cleanups to firmware capability detection.
- * o Arrange for orinoco_pci.c to override firmware detection.
- * We should be able to support the PCI Intersil cards now.
- * o Cleanup handling of reset_cor and hard_reset (Pavel Roskin).
- * o Remove erroneous use of USER_BAP in the TxExc handler (Jouni
- * Malinen).
- * o Makefile changes for better integration into David Hinds
- * pcmcia-cs package.
- *
- * v0.11a -> v0.11b - 1 May 2002 - David Gibson
- * o Better error reporting in orinoco_plx_init_one()
- * o Fixed multiple bad kfree() bugs introduced by the
- * alloc_orinocodev() changes.
- *
- * v0.11b -> v0.12 - 19 Jun 2002 - David Gibson
- * o Support changing the MAC address.
- * o Correct display of Intersil firmware revision numbers.
- * o Entirely revised locking scheme. Should be both simpler and
- * better.
- * o Merged some common code in orinoco_plx, orinoco_pci and
- * airport by creating orinoco_default_{open,stop,reset}()
- * which are used as the dev->open, dev->stop, priv->reset
- * callbacks if none are specified when alloc_orinocodev() is
- * called.
- * o Removed orinoco_plx_interrupt() and orinoco_pci_interrupt().
- * They didn't do anything.
- *
- * v0.12 -> v0.12a - 4 Jul 2002 - David Gibson
- * o Some rearrangement of code.
- * o Numerous fixups to locking and rest handling, particularly
- * for PCMCIA.
- * o This allows open and stop net_device methods to be in
- * orinoco.c now, rather than in the init modules.
- * o In orinoco_cs.c link->priv now points to the struct
- * net_device not to the struct orinoco_private.
- * o Added a check for undersized SNAP frames, which could cause
- * crashes.
- *
- * v0.12a -> v0.12b - 11 Jul 2002 - David Gibson
- * o Fix hw->num_init testing code, so num_init is actually
- * incremented.
- * o Fix very stupid bug in orinoco_cs which broke compile with
- * CONFIG_SMP.
- * o Squashed a warning.
- *
- * v0.12b -> v0.12c - 26 Jul 2002 - David Gibson
- * o Change to C9X style designated initializers.
- * o Add support for 3Com AirConnect PCI.
- * o No longer ignore the hard_reset argument to
- * alloc_orinocodev(). Oops.
- *
- * v0.12c -> v0.13beta1 - 13 Sep 2002 - David Gibson
- * o Revert the broken 0.12* locking scheme and go to a new yet
- * simpler scheme.
- * o Do firmware resets only in orinoco_init() and when waking
- * the card from hard sleep.
- *
- * v0.13beta1 -> v0.13 - 27 Sep 2002 - David Gibson
- * o Re-introduced full resets (via schedule_task()) on Tx
- * timeout.
- *
- * v0.13 -> v0.13a - 30 Sep 2002 - David Gibson
- * o Minor cleanups to info frame handling. Add basic support
- * for linkstatus info frames.
- * o Include required kernel headers in orinoco.h, to avoid
- * compile problems.
- *
- * v0.13a -> v0.13b - 10 Feb 2003 - David Gibson
- * o Implemented hard reset for Airport cards
- * o Experimental suspend/resume implementation for orinoco_pci
- * o Abolished /proc debugging support, replaced with a debugging
- * iwpriv. Now it's ugly and simple instead of ugly and complex.
- * o Bugfix in hermes.c if the firmware returned a record length
- * of 0, we could go clobbering memory.
- * o Bugfix in orinoco_stop() - it used to fail if hw_unavailable
- * was set, which was usually true on PCMCIA hot removes.
- * o Track LINKSTATUS messages, silently drop Tx packets before
- * we are connected (avoids confusing the firmware), and only
- * give LINKSTATUS printk()s if the status has changed.
- *
- * v0.13b -> v0.13c - 11 Mar 2003 - David Gibson
- * o Cleanup: use dev instead of priv in various places.
- * o Bug fix: Don't ReleaseConfiguration on RESET_PHYSICAL event
- * if we're in the middle of a (driver initiated) hard reset.
- * o Bug fix: ETH_ZLEN is supposed to include the header
- * (Dionysus Blazakis & Manish Karir)
- * o Convert to using workqueues instead of taskqueues (and
- * backwards compatibility macros for pre 2.5.41 kernels).
- * o Drop redundant (I think...) MOD_{INC,DEC}_USE_COUNT in
- * airport.c
- * o New orinoco_tmd.c init module from Joerg Dorchain for
- * TMD7160 based PCI to PCMCIA bridges (similar to
- * orinoco_plx.c).
- *
- * v0.13c -> v0.13d - 22 Apr 2003 - David Gibson
- * o Make hw_unavailable a counter, rather than just a flag, this
- * is necessary to avoid some races (such as a card being
- * removed in the middle of orinoco_reset().
- * o Restore Release/RequestConfiguration in the PCMCIA event handler
- * when dealing with a driver initiated hard reset. This is
- * necessary to prevent hangs due to a spurious interrupt while
- * the reset is in progress.
- * o Clear the 802.11 header when transmitting, even though we
- * don't use it. This fixes a long standing bug on some
- * firmwares, which seem to get confused if that isn't done.
- * o Be less eager to de-encapsulate SNAP frames, only do so if
- * the OUI is 00:00:00 or 00:00:f8, leave others alone. The old
- * behaviour broke CDP (Cisco Discovery Protocol).
- * o Use dev instead of priv for free_irq() as well as
- * request_irq() (oops).
- * o Attempt to reset rather than giving up if we get too many
- * IRQs.
- * o Changed semantics of __orinoco_down() so it can be called
- * safely with hw_unavailable set. It also now clears the
- * linkstatus (since we're going to have to reassociate).
- *
- * v0.13d -> v0.13e - 12 May 2003 - David Gibson
- * o Support for post-2.5.68 return values from irq handler.
- * o Fixed bug where underlength packets would be double counted
- * in the rx_dropped statistics.
- * o Provided a module parameter to suppress linkstatus messages.
- *
- * v0.13e -> v0.14alpha1 - 30 Sep 2003 - David Gibson
- * o Replaced priv->connected logic with netif_carrier_on/off()
- * calls.
- * o Remove has_ibss_any and never set the CREATEIBSS RID when
- * the ESSID is empty. Too many firmwares break if we do.
- * o 2.6 merges: Replace pdev->slot_name with pci_name(), remove
- * __devinitdata from PCI ID tables, use free_netdev().
- * o Enabled shared-key authentication for Agere firmware (from
- * Robert J. Moore <Robert.J.Moore AT allanbank.com>
- * o Move netif_wake_queue() (back) to the Tx completion from the
- * ALLOC event. This seems to prevent/mitigate the rolling
- * error -110 problems at least on some Intersil firmwares.
- * Theoretically reduces performance, but I can't measure it.
- * Patch from Andrew Tridgell <tridge AT samba.org>
- *
- * v0.14alpha1 -> v0.14alpha2 - 20 Oct 2003 - David Gibson
- * o Correctly turn off shared-key authentication when requested
- * (bugfix from Robert J. Moore).
- * o Correct airport sleep interfaces for current 2.6 kernels.
- * o Add code for key change without disabling/enabling the MAC
- * port. This is supposed to allow 802.1x to work sanely, but
- * doesn't seem to yet.
- *
* TODO
- * o New wireless extensions API (patch from Moustafa
- * Youssef, updated by Jim Carter and Pavel Roskin).
* o Handle de-encapsulation within network layer, provide 802.11
* headers (patch from Thomas 'Dent' Mirlacher)
- * o RF monitor mode support
* o Fix possible races in SPY handling.
* o Disconnect wireless extensions from fundamental configuration.
* o (maybe) Software WEP support (patch from Stano Meduna).

- bind_request() and bind_device() are merged by now. Register_client()
- is called right at the end of bind_request(), during the driver's
- ->attach() call. Individual descriptions:
-
- bind_request() connects a socket to a particular client driver.
- It looks up the specified device ID in the list of registered
- drivers, binds it to the socket, and tries to create an instance
- of the device. unbind_request() deletes a driver instance.
-
- Bind_device() associates a device driver with a particular socket.
- It is normally called by Driver Services after it has identified
- a newly inserted card. An instance of that driver will then be
- eligible to register as a client of this socket.
-
- Register_client() uses the dev_info_t handle to match the
- caller with a socket. The driver must have already been bound
- to a socket with bind_device() -- in fact, bind_device()
- allocates the client structure that will be used.

- * 1.7+: - See the check-in logs
- *
- * 1.6: - No longer opens a connection if the firmware is not loaded
- * - Added support for the speedtouch 330
- * - Removed the limit on the number of devices
- * - Module now autoloads on device plugin
- * - Merged relevant parts of sarlib
- * - Replaced the kernel thread with a tasklet
- * - New packet transmission code
- * - Changed proc file contents
- * - Fixed all known SMP races
- * - Many fixes and cleanups
- * - Various fixes by Oliver Neukum (oliver@neukum.name)
- *
- * 1.5A: - Version for inclusion in 2.5 series kernel
- * - Modifications by Richard Purdie (rpurdie@rpsys.net)
- * - made compatible with kernel 2.5.6 onwards by changing
- * udsl_usb_send_data_context->urb to a pointer and adding code
- * to alloc and free it
- * - remove_wait_queue() added to udsl_atm_processqueue_thread()
- *
- * 1.5: - fixed memory leak when atmsar_decode_aal5 returned NULL.
- * (reported by stephen.robinson@zen.co.uk)
- *
- * 1.4: - changed the spin_lock() under interrupt to spin_lock_irqsave()
- * - unlink all active send urbs of a vcc that is being closed.
- *
- * 1.3.1: - added the version number
- *
- * 1.3: - Added multiple send urb support
- * - fixed memory leak and vcc->tx_inuse starvation bug
- * when not enough memory left in vcc.
- *
- * 1.2: - Fixed race condition in udsl_usb_send_data()
- * 1.1: - Turned off packet debugging

+ * Written by Johan Verrept, Duncan Sands (duncan.sands@free.fr) and David Woodhouse
+ *
+ * 1.7+: - See the check-in logs
+ *
+ * 1.6: - No longer opens a connection if the firmware is not loaded
+ * - Added support for the speedtouch 330
+ * - Removed the limit on the number of devices
+ * - Module now autoloads on device plugin
+ * - Merged relevant parts of sarlib
+ * - Replaced the kernel thread with a tasklet
+ * - New packet transmission code
+ * - Changed proc file contents
+ * - Fixed all known SMP races
+ * - Many fixes and cleanups
+ * - Various fixes by Oliver Neukum (oliver@neukum.name)
+ *
+ * 1.5A: - Version for inclusion in 2.5 series kernel
+ * - Modifications by Richard Purdie (rpurdie@rpsys.net)
+ * - made compatible with kernel 2.5.6 onwards by changing
+ * usbatm_usb_send_data_context->urb to a pointer and adding code
+ * to alloc and free it
+ * - remove_wait_queue() added to usbatm_atm_processqueue_thread()
+ *
+ * 1.5: - fixed memory leak when atmsar_decode_aal5 returned NULL.
+ * (reported by stephen.robinson@zen.co.uk)
+ *
+ * 1.4: - changed the spin_lock() under interrupt to spin_lock_irqsave()
+ * - unlink all active send urbs of a vcc that is being closed.
+ *
+ * 1.3.1: - added the version number
+ *
+ * 1.3: - Added multiple send urb support
+ * - fixed memory leak and vcc->tx_inuse starvation bug
+ * when not enough memory left in vcc.
+ *
+ * 1.2: - Fixed race condition in usbatm_usb_send_data()
+ * 1.1: - Turned off packet debugging
