Merge tag 'regmap-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap updates from Mark Brown:
"A surprisingly large series of updates for regmap this time, mostly
due to all the work Stephen Warren has done to add support for MMIO
buses. This wasn't really the target for the framework but it turns
out that there's a reasonable number of cases where it's very helpful
to use the register cache support to allow the register map to remain
available while the device is suspended.
- A MMIO bus implementation, contributed by Stephen Warren. Currently
this is limited to 32 bit systems and native endian registers.
- Support for naming register maps, mainly intended for MMIO devices
with multiple register banks. This was also contributed by Stephen
Warren.
- Support for register striding, again contributed by Stephen Warren
and mainly intended for use with MMIO as typically the registers
will be a fixed size but byte addressed.
- irqdomain support for the generic regmap irq_chip, including support
for dynamically allocate interrupt numbers.
- A function dev_get_regmap() which allows frameworks using regmap to
obtain the regmap for a device from the struct device, making life a
little simpler for them.
- Updates to regmap-irq to support more chips (contributed by Graeme
Gregory) and to use irqdomains.
- Support for devices with 24 bit register addresses.
The striding support collided with all the topic branches so the
branches look a bit messy and eventually I just gave up. There's also
the TI Palmas driver and a couple of other isolated MFD patches that
all depend on new regmap features so are being merged here."

+* ARM architected timer
+
+ARM Cortex-A7 and Cortex-A15 have a per-core architected timer, which

+
+Example:
+
+ timer {

-3COM PCI TOKEN LINK VELOCITY XL TOKEN RING CARDS README
-
-Release 0.9.0 - Release
- Jul 17th 2000 Mike Phillips
-
- 1.2.0 - Final
- Feb 17th 2002 Mike Phillips
- Updated for submission to the 2.4.x kernel.
-
-Thanks:
- Terry Murphy from 3Com for tech docs and support,
- Adam D. Ligas for testing the driver.
-
-Note:
- This driver will NOT work with the 3C339 Token Ring cards, you need
-to use the tms380 driver instead.
-
-Options:
-
-The driver accepts three options: ringspeed, pkt_buf_sz and message_level.
-
-These options can be specified differently for each card found.
-
-ringspeed: Has one of three settings 0 (default), 4 or 16. 0 will
-make the card autosense the ringspeed and join at the appropriate speed,
-this will be the default option for most people. 4 or 16 allow you to
-explicitly force the card to operate at a certain speed. The card will fail
-if you try to insert it at the wrong speed. (Although some hubs will allow
-this so be *very* careful). The main purpose for explicitly setting the ring
-speed is for when the card is first on the ring. In autosense mode, if the card
-cannot detect any active monitors on the ring it will open at the same speed as
-its last opening. This can be hazardous if this speed does not match the speed
-you want the ring to operate at.
-
-pkt_buf_sz: This is this initial receive buffer allocation size. This will
-default to 4096 if no value is entered. You may increase performance of the
-driver by setting this to a value larger than the network packet size, although
-the driver now re-sizes buffers based on MTU settings as well.
-
-message_level: Controls level of messages created by the driver. Defaults to 0:
-which only displays start-up and critical messages. Presently any non-zero
-value will display all soft messages as well. NB This does not turn
-debugging messages on, that must be done by modified the source code.
-
-Variable MTU size:
-
-The driver can handle a MTU size up to either 4500 or 18000 depending upon
-ring speed. The driver also changes the size of the receive buffers as part
-of the mtu re-sizing, so if you set mtu = 18000, you will need to be able
-to allocate 16 * (sk_buff with 18000 buffer size) call it 18500 bytes per ring
-position = 296,000 bytes of memory space, plus of course anything
-necessary for the tx sk_buff's. Remember this is per card, so if you are
-building routers, gateway's etc, you could start to use a lot of memory
-real fast.

Introduction

+The MAC is the middle layer in the IEEE 802.15.4 Linux stack. This moment it

See header include/net/mac802154.h and several drivers in drivers/ieee802154/.

+Device drivers API
+==================
+
+The include/net/mac802154.h defines following functions:
+ - struct ieee802154_dev *ieee802154_alloc_device
+ (size_t priv_size, struct ieee802154_ops *ops):

+In addition there are two drivers available which simulate real devices with
+HardMAC (fakehard) and SoftMAC (fakelb - IEEE 802.15.4 loopback driver)
+interfaces. This option provides possibility to test and debug stack without
+usage of real hardware.

-IBM PCI Pit/Pit-Phy/Olympic CHIPSET BASED TOKEN RING CARDS README
-
-Release 0.2.0 - Release
- June 8th 1999 Peter De Schrijver & Mike Phillips
-Release 0.9.C - Release
- April 18th 2001 Mike Phillips
-
-Thanks:
-Erik De Cock, Adrian Bridgett and Frank Fiene for their
-patience and testing.
-Donald Champion for the cardbus support
-Kyle Lucke for the dma api changes.
-Jonathon Bitner for hardware support.
-Everybody on linux-tr for their continued support.
-
-Options:
-
-The driver accepts four options: ringspeed, pkt_buf_sz,
-message_level and network_monitor.
-
-These options can be specified differently for each card found.
-
-ringspeed: Has one of three settings 0 (default), 4 or 16. 0 will
-make the card autosense the ringspeed and join at the appropriate speed,
-this will be the default option for most people. 4 or 16 allow you to
-explicitly force the card to operate at a certain speed. The card will fail
-if you try to insert it at the wrong speed. (Although some hubs will allow
-this so be *very* careful). The main purpose for explicitly setting the ring
-speed is for when the card is first on the ring. In autosense mode, if the card
-cannot detect any active monitors on the ring it will not open, so you must
-re-init the card at the appropriate speed. Unfortunately at present the only
-way of doing this is rmmod and insmod which is a bit tough if it is compiled
-in the kernel.
-
-pkt_buf_sz: This is this initial receive buffer allocation size. This will
-default to 4096 if no value is entered. You may increase performance of the
-driver by setting this to a value larger than the network packet size, although
-the driver now re-sizes buffers based on MTU settings as well.
-
-message_level: Controls level of messages created by the driver. Defaults to 0:
-which only displays start-up and critical messages. Presently any non-zero
-value will display all soft messages as well. NB This does not turn
-debugging messages on, that must be done by modified the source code.
-
-network_monitor: Any non-zero value will provide a quasi network monitoring
-mode. All unexpected MAC frames (beaconing etc.) will be received
-by the driver and the source and destination addresses printed.
-Also an entry will be added in /proc/net called olympic_tr%d, where tr%d
-is the registered device name, i.e tr0, tr1, etc. This displays low
-level information about the configuration of the ring and the adapter.
-This feature has been designed for network administrators to assist in
-the diagnosis of network / ring problems. (This used to OLYMPIC_NETWORK_MONITOR,
-but has now changed to allow each adapter to be configured differently and
-to alleviate the necessity to re-compile olympic to turn the option on).
-
-Multi-card:
-
-The driver will detect multiple cards and will work with shared interrupts,
-each card is assigned the next token ring device, i.e. tr0 , tr1, tr2. The
-driver should also happily reside in the system with other drivers. It has
-been tested with ibmtr.c running, and I personally have had one Olicom PCI
-card and two IBM olympic cards (all on the same interrupt), all running
-together.
-
-Variable MTU size:
-
-The driver can handle a MTU size up to either 4500 or 18000 depending upon
-ring speed. The driver also changes the size of the receive buffers as part
-of the mtu re-sizing, so if you set mtu = 18000, you will need to be able
-to allocate 16 * (sk_buff with 18000 buffer size) call it 18500 bytes per ring
-position = 296,000 bytes of memory space, plus of course anything
-necessary for the tx sk_buff's. Remember this is per card, so if you are
-building routers, gateway's etc, you could start to use a lot of memory
-real fast.

-Text File for the SMC TokenCard TokenRing Linux driver (smctr.c).
- By Jay Schulist <jschlst@samba.org>
-
-The Linux SMC Token Ring driver works with the SMC TokenCard Elite (8115T)
-ISA and SMC TokenCard Elite/A (8115T/A) MCA adapters.
-
-Latest information on this driver can be obtained on the Linux-SNA WWW site.
-Please point your browser to: http://www.linux-sna.org
-
-This driver is rather simple to use. Select Y to Token Ring adapter support
-in the kernel configuration. A choice for SMC Token Ring adapters will
-appear. This drives supports all SMC ISA/MCA adapters. Choose this
-option. I personally recommend compiling the driver as a module (M), but if you
-you would like to compile it statically answer Y instead.
-
-This driver supports multiple adapters without the need to load multiple copies
-of the driver. You should be able to load up to 7 adapters without any kernel
-modifications, if you are in need of more please contact the maintainer of this
-driver.
-
-Load the driver either by lilo/loadlin or as a module. When a module using the

-
-Now just setup the device via ifconfig and set and routes you may have. After
-this you are ready to start sending some tokens.
-
-Errata:
-1). For anyone wondering where to pick up the SMC adapters please browse
- to http://www.smc.com
-
-2). If you are the first/only Token Ring Client on a Token Ring LAN, please
- specify the ringspeed with the ringspeed=[4/16] module option. If no
- ringspeed is specified the driver will attempt to autodetect the ring
- speed and/or if the adapter is the first/only station on the ring take
- the appropriate actions.
-
- NOTE: Default ring speed is 16MB UTP.
-
-3). PnP support for this adapter sucks. I recommend hard setting the
- IO/MEM/IRQ by the jumpers on the adapter. If this is not possible
- load the module with the following io=[ioaddr] mem=[mem_addr]
- irq=[irq_num].

+HCI backend for NFC Core
+
+Author: Eric Lapuyade, Samuel Ortiz
+Contact: eric.lapuyade@intel.com, samuel.ortiz@intel.com
+
+General
+-------
+
+The HCI layer implements much of the ETSI TS 102 622 V10.2.0 specification. It
+enables easy writing of HCI-based NFC drivers. The HCI layer runs as an NFC Core
+backend, implementing an abstract nfc device and translating NFC Core API
+to HCI commands and events.
+
+HCI
+---
+
+HCI registers as an nfc device with NFC Core. Requests coming from userspace are
+routed through netlink sockets to NFC Core and then to HCI. From this point,
+they are translated in a sequence of HCI commands sent to the HCI layer in the
+host controller (the chip). The sending context blocks while waiting for the
+response to arrive.
+HCI events can also be received from the host controller. They will be handled
+and a translation will be forwarded to NFC Core as needed.
+HCI uses 2 execution contexts:
+- one if for executing commands : nfc_hci_msg_tx_work(). Only one command
+can be executing at any given moment.
+- one if for dispatching received events and responses : nfc_hci_msg_rx_work()
+
+HCI Session initialization:
+---------------------------
+
+The Session initialization is an HCI standard which must unfortunately
+support proprietary gates. This is the reason why the driver will pass a list
+of proprietary gates that must be part of the session. HCI will ensure all
+those gates have pipes connected when the hci device is set up.
+
+HCI Gates and Pipes
+-------------------
+
+A gate defines the 'port' where some service can be found. In order to access
+a service, one must create a pipe to that gate and open it. In this
+implementation, pipes are totally hidden. The public API only knows gates.
+This is consistent with the driver need to send commands to proprietary gates
+without knowing the pipe connected to it.
+
+Driver interface
+----------------
+
+A driver would normally register itself with HCI and provide the following
+entry points:
+
+struct nfc_hci_ops {
+ int (*open)(struct nfc_hci_dev *hdev);
+ void (*close)(struct nfc_hci_dev *hdev);
+ int (*xmit)(struct nfc_hci_dev *hdev, struct sk_buff *skb);
+ int (*start_poll)(struct nfc_hci_dev *hdev, u32 protocols);
+ int (*target_from_gate)(struct nfc_hci_dev *hdev, u8 gate,
+ struct nfc_target *target);
+};
+
+open() and close() shall turn the hardware on and off. xmit() shall simply
+write a frame to the chip. start_poll() is an optional entrypoint that shall
+set the hardware in polling mode. This must be implemented only if the hardware
+uses proprietary gates or a mechanism slightly different from the HCI standard.
+target_from_gate() is another optional entrypoint to return the protocols
+corresponding to a proprietary gate.
+
+On the rx path, the driver is responsible to push incoming HCP frames to HCI
+using nfc_hci_recv_frame(). HCI will take care of re-aggregation and handling
+This must be done from a context that can sleep.
+
+SHDLC
+-----
+
+Most chips use shdlc to ensure integrity and delivery ordering of the HCP
+frames between the host controller (the chip) and hosts (entities connected
+to the chip, like the cpu). In order to simplify writing the driver, an shdlc
+layer is available for use by the driver.
+When used, the driver actually registers with shdlc, and shdlc will register
+with HCI. HCI sees shdlc as the driver and thus send its HCP frames
+through shdlc->xmit.
+SHDLC adds a new execution context (nfc_shdlc_sm_work()) to run its state
+machine and handle both its rx and tx path.
+
+Included Drivers
+----------------
+
+An HCI based driver for an NXP PN544, connected through I2C bus, and using
+shdlc is included.
+
+Execution Contexts
+------------------
+
+The execution contexts are the following:
+- IRQ handler (IRQH):
+fast, cannot sleep. stores incoming frames into an shdlc rx queue
+
+- SHDLC State Machine worker (SMW)
+handles shdlc rx & tx queues. Dispatches HCI cmd responses.
+
+- HCI Tx Cmd worker (MSGTXWQ)
+Serialize execution of HCI commands. Complete execution in case of resp timeout.
+
+- HCI Rx worker (MSGRXWQ)
+Dispatches incoming HCI commands or events.
+
+- Syscall context from a userspace call (SYSCALL)
+Any entrypoint in HCI called from NFC Core
+
+Workflow executing an HCI command (using shdlc)
+-----------------------------------------------
+
+Executing an HCI command can easily be performed synchronously using the
+following API:
+
+int nfc_hci_send_cmd (struct nfc_hci_dev *hdev, u8 gate, u8 cmd,
+ const u8 *param, size_t param_len, struct sk_buff **skb)
+
+The API must be invoked from a context that can sleep. Most of the time, this
+will be the syscall context. skb will return the result that was received in
+the response.
+
+Internally, execution is asynchronous. So all this API does is to enqueue the
+HCI command, setup a local wait queue on stack, and wait_event() for completion.
+The wait is not interruptible because it is guaranteed that the command will
+complete after some short timeout anyway.
+
+MSGTXWQ context will then be scheduled and invoke nfc_hci_msg_tx_work().
+This function will dequeue the next pending command and send its HCP fragments
+to the lower layer which happens to be shdlc. It will then start a timer to be
+able to complete the command with a timeout error if no response arrive.
+
+SMW context gets scheduled and invokes nfc_shdlc_sm_work(). This function
+handles shdlc framing in and out. It uses the driver xmit to send frames and
+receives incoming frames in an skb queue filled from the driver IRQ handler.
+SHDLC I(nformation) frames payload are HCP fragments. They are agregated to
+form complete HCI frames, which can be a response, command, or event.
+
+HCI Responses are dispatched immediately from this context to unblock
+waiting command execution. Reponse processing involves invoking the completion
+callback that was provided by nfc_hci_msg_tx_work() when it sent the command.
+The completion callback will then wake the syscall context.
+
+Workflow receiving an HCI event or command
+------------------------------------------
+
+HCI commands or events are not dispatched from SMW context. Instead, they are
+queued to HCI rx_queue and will be dispatched from HCI rx worker
+context (MSGRXWQ). This is done this way to allow a cmd or event handler
+to also execute other commands (for example, handling the
+NFC_HCI_EVT_TARGET_DISCOVERED event from PN544 requires to issue an
+ANY_GET_PARAMETER to the reader A gate to get information on the target
+that was discovered).
+
+Typically, such an event will be propagated to NFC Core from MSGRXWQ context.

-BTFIXUP
--------
-
-To build new kernels you have to issue "make image". The ready kernel
-in ELF format is placed in arch/sparc/boot/image. Explanation is below.
-
-BTFIXUP is a unique feature of Linux/sparc among other architectures,
-developed by Jakub Jelinek (I think... Obviously David S. Miller took
-part, too). It allows to boot the same kernel at different
-sub-architectures, such as sun4c, sun4m, sun4d, where SunOS uses
-different kernels. This feature is convinient for people who you move
-disks between boxes and for distrution builders.
-
-To function, BTFIXUP must link the kernel "in the draft" first,
-analyze the result, write a special stub code based on that, and
-build the final kernel with the stub (btfix.o).
-
-Kai Germaschewski improved the build system of the kernel in the 2.5 series
-significantly. Unfortunately, the traditional way of running the draft
-linking from architecture specific Makefile before the actual linking
-by generic Makefile is nearly impossible to support properly in the
-new build system. Therefore, the way we integrate BTFIXUP with the
-build system was changed in 2.5.40. Now, generic Makefile performs
-the draft linking and stores the result in file vmlinux. Architecture
-specific post-processing invokes BTFIXUP machinery and final linking
-in the same way as other architectures do bootstraps.
-
-Implications of that change are as follows.
-
-1. Hackers must type "make image" now, instead of just "make", in the same
- way as s390 people do now. It is analogous to "make bzImage" on i386.
- This does NOT affect sparc64, you continue to use "make" to build sparc64
- kernels.
-
-2. vmlinux is not the final kernel, so RPM builders have to adjust
- their spec files (if they delivered vmlinux for debugging).
- System.map generated for vmlinux is still valid.
-
-3. Scripts that produce a.out images have to be changed. First, if they
- invoke make, they have to use "make image". Second, they have to pick up
- the new kernel in arch/sparc/boot/image instead of vmlinux.
-
-4. Since we are compliant with Kai's build system now, make -j is permitted.

- * Normally, with the shift-and-add approach, if both numbers are
- * positive you get the correct result. With 32-bit two's-complement
- * numbers, -x is represented as
- *
- * x 32
- * ( 2 - ------ ) mod 2 * 2
- * 32
- * 2
- *
- * (the `mod 2' subtracts 1 from 1.bbbb). To avoid lots of 2^32s,
- * we can treat this as if the radix point were just to the left
- * of the sign bit (multiply by 2^32), and get
- *
- * -x = (2 - x) mod 2
- *
- * Then, ignoring the `mod 2's for convenience:
- *
- * x * y = xy
- * -x * y = 2y - xy
- * x * -y = 2x - xy
- * -x * -y = 4 - 2x - 2y + xy
- *
- * For signed multiplies, we subtract (x << 32) from the partial
- * product to fix this problem for negative multipliers (see mul.s).
- * Because of the way the shift into the partial product is calculated
- * (N xor V), this term is automatically removed for the multiplicand,
- * so we don't have to adjust.
- *
- * But for unsigned multiplies, the high order bit wasn't a sign bit,
- * and the correction is wrong. So for unsigned multiplies where the
- * high order bit is one, we end up with xy - (y << 32). To fix it
- * we add y << 32.

+/* A note about branch offset calculations. The addrs[] array,
+ * indexed by BPF instruction, records the address after all the
+ * sparc instructions emitted for that BPF instruction.
+ *
+ * The most common case is to emit a branch at the end of such
+ * a code sequence. So this would be two instructions, the
+ * branch and it's delay slot.
+ *
+ * Therefore by default the branch emitters calculate the branch
+ * offset field as:
+ *
+ * destination - (addrs[i] - 8)
+ *
+ * This "addrs[i] - 8" is the address of the branch itself or
+ * what "." would be in assembler notation. The "8" part is
+ * how we take into consideration the branch and it's delay
+ * slot mentioned above.
+ *
+ * Sometimes we need to emit a branch earlier in the code
+ * sequence. And in these situations we adjust "destination"
+ * to accomodate this difference. For example, if we needed
+ * to emit a branch (and it's delay slot) right before the
+ * final instruction emitted for a BPF opcode, we'd use
+ * "destination + 4" instead of just plain "destination" above.
+ *
+ * This is why you see all of these funny emit_branch() and
+ * emit_jump() calls with adjusted offsets.

- * If 1..15 or 17..31, an alternate time slot is used for D-channel.
- * In this case, the application must be able to handle this.
- * If -1 is given, the D-channel is disabled and all 31 slots can be used

+ * dmask and bmask:
+ * NOTE: One dmask value must be given for every HFC-E1 card.
+ * If omitted, the E1 card has D-channel on time slot 16, which is default.
+ * dmask is a 32 bit mask. The bit must be set for an alternate time slot.
+ * If multiple bits are set, multiple virtual card fragments are created.
+ * For each bit set, a bmask value must be given. Each bit on the bmask
+ * value stands for a B-channel. The bmask may not overlap with dmask or
+ * with other bmask values for that card.
+ * Example: dmask=0x00020002 bmask=0x0000fffc,0xfffc0000
+ * This will create one fragment with D-channel on slot 1 with
+ * B-channels on slots 2..15, and a second fragment with D-channel
+ * on slot 17 with B-channels on slot 18..31. Slot 16 is unused.
+ * If bit 0 is set (dmask=0x00000001) the D-channel is on slot 0 and will
+ * not function.
+ * Example: dmask=0x00000001 bmask=0xfffffffe
+ * This will create a port with all 31 usable timeslots as
+ * B-channels.
+ * If no bits are set on bmask, no B-channel is created for that fragment.
+ * Example: dmask=0xfffffffe bmask=0,0,0,0.... (31 0-values for bmask)
+ * This will create 31 ports with one D-channel only.

-/* ne2.c: A NE/2 Ethernet Driver for Linux. */
-/*
- Based on the NE2000 driver written by Donald Becker (1992-94).
- modified by Wim Dumon (Apr 1996)
-
- This software may be used and distributed according to the terms
- of the GNU General Public License, incorporated herein by reference.
-
- The author may be reached as wimpie@linux.cc.kuleuven.ac.be
-
- Currently supported: NE/2
- This patch was never tested on other MCA-ethernet adapters, but it
- might work. Just give it a try and let me know if you have problems.
- Also mail me if it really works, please!
-
- Changelog:
- Mon Feb 3 16:26:02 MET 1997
- - adapted the driver to work with the 2.1.25 kernel

- - module support (untested)
-
- Fri Aug 28 00:18:36 CET 1998 (David Weinehall)
- - fixed a few minor typos
- - made the MODULE_PARM conditional (it only works with the v2.1.x kernels)
- - fixed the module support (Now it's working...)
-
- Mon Sep 7 19:01:44 CET 1998 (David Weinehall)
- - added support for Arco Electronics AE/2-card (experimental)

- - Miscellaneous bugfixes
-
- Tue Sep 19 16:21:12 CET 1998 (Magnus Jonsson)
- - Cleanup
-
- Wed Sep 23 14:33:34 CET 1998 (David Weinehall)
- - Restructuring and rewriting for v2.1.x compliance
-
- Wed Oct 14 17:19:21 CET 1998 (David Weinehall)
- - Added code that unregisters irq and proc-info
- - Version# bump
-
- Mon Nov 16 15:28:23 CET 1998 (Wim Dumon)
- - pass 'dev' as last parameter of request_irq in stead of 'NULL'
-
- Wed Feb 7 21:24:00 CET 2001 (Alfred Arnold)
- - added support for the D-Link DE-320CT
-
- * WARNING
- -------
- This is alpha-test software. It is not guaranteed to work. As a
- matter of fact, I'm quite sure there are *LOTS* of bugs in here. I
- would like to hear from you if you use this driver, even if it works.
- If it doesn't work, be sure to send me a mail with the problems !

-/* smc-mca.c: A SMC Ultra ethernet driver for linux. */
-/*
- Most of this driver, except for ultramca_probe is nearly
- verbatim from smc-ultra.c by Donald Becker. The rest is
- written and copyright 1996 by David Weis, weisd3458@uni.edu
-
- This is a driver for the SMC Ultra and SMC EtherEZ ethercards.
-
- This driver uses the cards in the 8390-compatible, shared memory mode.
- Most of the run-time complexity is handled by the generic code in
- 8390.c.
-
- This driver enables the shared memory only when doing the actual data
- transfers to avoid a bug in early version of the card that corrupted
- data transferred by a AHA1542.
-
- This driver does not support the programmed-I/O data transfer mode of
- the EtherEZ. That support (if available) is smc-ez.c. Nor does it
- use the non-8390-compatible "Altego" mode. (No support currently planned.)
-
- Changelog:
-
- Paul Gortmaker : multiple card support for module users.
- David Weis : Micro Channel-ized it.
- Tom Sightler : Added support for IBM PS/2 Ethernet Adapter/A
- Christopher Turcksin : Changed MCA-probe so that multiple adapters are
- found correctly (Jul 16, 1997)
- Chris Beauregard : Tried to merge the two changes above (Dec 15, 1997)
- Tom Sightler : Fixed minor detection bug caused by above merge
- Tom Sightler : Added support for three more Western Digital
- MCA-adapters
- Tom Sightler : Added support for 2.2.x mca_find_unused_adapter
- Hartmut Schmidt : - Modified parameter detection to handle each
- card differently depending on a switch-list
- - 'card_ver' removed from the adapter list
- - Some minor bug fixes

- Support for MCA EtherWORKS cards added 11-3-98.
+ Support for MCA EtherWORKS cards added 11-3-98. (MCA since deleted)
Verified to work with up to 2 DE212 cards in a system (although not
fully stress-tested).
- Currently known bugs/limitations:
-
- Note: with the MCA stuff as a module, it trusts the MCA configuration,
- not the command line for IRQ and memory address. You can
- specify them if you want, but it will throw your values out.
- You still have to pass the IO address it was configured as
- though.

-
- Changelog:
-
- Mike Cruse : mcruse@cti-ltd.com
- : Changes for Linux 2.0 compatibility.
- : Added dev_id parameter in net_interrupt(),
- : request_irq() and free_irq(). Just NULL for now.
-
- Mike Cruse : Added MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros
- : in net_open() and net_close() so kerneld would know
- : that the module is in use and wouldn't eject the
- : driver prematurely.
-
- Mike Cruse : Rewrote init_module() and cleanup_module using 8390.c
- : as an example. Disabled autoprobing in init_module(),
- : not a good thing to do to other devices while Linux
- : is running from all accounts.
-
- Russ Nelson : Jul 13 1998. Added RxOnly DMA support.
-
- Melody Lee : Aug 10 1999. Changes for Linux 2.2.5 compatibility.
- : email: ethernet@crystal.cirrus.com
-
- Alan Cox : Removed 1.2 support, added 2.1 extra counters.
-
- Andrew Morton : Kernel 2.3.48
- : Handle kmalloc() failures
- : Other resource allocation fixes
- : Add SMP locks
- : Integrate Russ Nelson's ALLOW_DMA functionality back in.
- : If ALLOW_DMA is true, make DMA runtime selectable
- : Folded in changes from Cirrus (Melody Lee
- : <klee@crystal.cirrus.com>)
- : Don't call netif_wake_queue() in net_send_packet()
- : Fixed an out-of-mem bug in dma_rx()
- : Updated Documentation/networking/cs89x0.txt
-
- Andrew Morton : Kernel 2.3.99-pre1
- : Use skb_reserve to longword align IP header (two places)
- : Remove a delay loop from dma_rx()
- : Replace '100' with HZ
- : Clean up a couple of skb API abuses
- : Added 'cs89x0_dma=N' kernel boot option
- : Correctly initialise lp->lock in non-module compile
-
- Andrew Morton : Kernel 2.3.99-pre4-1
- : MOD_INC/DEC race fix (see
- : http://www.uwsg.indiana.edu/hypermail/linux/kernel/0003.3/1532.html)
-
- Andrew Morton : Kernel 2.4.0-test7-pre2
- : Enhanced EEPROM support to cover more devices,
- : abstracted IRQ mapping to support CONFIG_ARCH_CLPS7500 arch
- : (Jason Gunthorpe <jgg@ualberta.ca>)
-
- Andrew Morton : Kernel 2.4.0-test11-pre4
- : Use dev->name in request_*() (Andrey Panin)
- : Fix an error-path memleak in init_module()
- : Preserve return value from request_irq()
- : Fix type of `media' module parm (Keith Owens)
- : Use SET_MODULE_OWNER()
- : Tidied up strange request_irq() abuse in net_open().
-
- Andrew Morton : Kernel 2.4.3-pre1
- : Request correct number of pages for DMA (Hugh Dickens)
- : Select PP_ChipID _after_ unregister_netdev in cleanup_module()
- : because unregister_netdev() calls get_stats.
- : Make `version[]' __initdata
- : Uninlined the read/write reg/word functions.
-
- Oskar Schirmer : oskar@scara.com
- : HiCO.SH4 (superh) support added (irq#1, cs89x0_media=)
-
- Deepak Saxena : dsaxena@plexity.net
- : Intel IXDP2x01 (XScale ixp2x00 NPU) platform support
-
- Dmitry Pervushin : dpervushin@ru.mvista.com
- : PNX010X platform support
-
- Deepak Saxena : dsaxena@plexity.net
- : Intel IXDP2351 platform support
-
- Dmitry Pervushin : dpervushin@ru.mvista.com
- : PNX010X platform support
-
- Domenico Andreoli : cavokz@gmail.com
- : QQ2440 platform support

- net-3-driver for the 3c523 Etherlink/MC card (i82586 Ethernet chip)
-
-
- This is an extension to the Linux operating system, and is covered by the

-
- Copyright 1995, 1996 by Chris Beauregard (cpbeaure@undergrad.math.uwaterloo.ca)
-
- This is basically Michael Hipp's ni52 driver, with a new probing
- algorithm and some minor changes to the 82586 CA and reset routines.
- Thanks a lot Michael for a really clean i82586 implementation! Unless
- otherwise documented in ni52.c, any bugs are mine.
-
- Contrary to the Ethernet-HOWTO, this isn't based on the 3c507 driver in
- any way. The ni52 is a lot easier to modify.
-
- sources:
- ni52.c
-
- Crynwr packet driver collection was a great reference for my first
- attempt at this sucker. The 3c507 driver also helped, until I noticed
- that ni52.c was a lot nicer.
-
- EtherLink/MC: Micro Channel Ethernet Adapter Technical Reference
- Manual, courtesy of 3Com CardFacts, documents the 3c523-specific
- stuff. Information on CardFacts is found in the Ethernet HOWTO.
- Also see <a href="http://www.3com.com/">
-
- Microprocessor Communications Support Chips, T.J. Byers, ISBN
- 0-444-01224-9, has a section on the i82586. It tells you just enough
- to know that you really don't want to learn how to program the chip.
-
- The original device probe code was stolen from ps2esdi.c
-
- Known Problems:
- Since most of the code was stolen from ni52.c, you'll run across the
- same bugs in the 0.62 version of ni52.c, plus maybe a few because of
- the 3c523 idiosynchacies. The 3c523 has 16K of RAM though, so there
- shouldn't be the overrun problem that the 8K ni52 has.
-
- This driver is for a 16K adapter. It should work fine on the 64K
- adapters, but it will only use one of the 4 banks of RAM. Modifying
- this for the 64K version would require a lot of heinous bank
- switching, which I'm sure not interested in doing. If you try to
- implement a bank switching version, you'll basically have to remember
- what bank is enabled and do a switch every time you access a memory
- location that's not current. You'll also have to remap pointers on
- the driver side, because it only knows about 16K of the memory.
- Anyone desperate or masochistic enough to try?
-
- It seems to be stable now when multiple transmit buffers are used. I
- can't see any performance difference, but then I'm working on a 386SX.
-
- Multicast doesn't work. It doesn't even pretend to work. Don't use
- it. Don't compile your kernel with multicast support. I don't know
- why.
-
- Features:
- This driver is useable as a loadable module. If you try to specify an
- IRQ or a IO address (via insmod 3c523.o irq=xx io=0xyyy), it will
- search the MCA slots until it finds a 3c523 with the specified
- parameters.
-
- This driver does support multiple ethernet cards when used as a module
- (up to MAX_3C523_CARDS, the default being 4)
-
- This has been tested with both BNC and TP versions, internal and
- external transceivers. Haven't tested with the 64K version (that I
- know of).
-
- History:
- Jan 1st, 1996
- first public release
- Feb 4th, 1996
- update to 1.3.59, incorporated multicast diffs from ni52.c
- Feb 15th, 1996
- added shared irq support
- Apr 1999
- added support for multiple cards when used as a module
- added option to disable multicast as is causes problems
- Ganesh Sittampalam <ganesh.sittampalam@magdalen.oxford.ac.uk>
- Stuart Adamson <stuart.adamson@compsoc.net>
- Nov 2001
- added support for ethtool (jgarzik)

-/**
- * DOC: Traps for the unwary
- *
- * The diagram (Figure 1-1) and the POS summary disagree with the
- * "Interrupt Level" section in the manual.
- *
- * The manual contradicts itself when describing the minimum number
- * buffers in the 'configure lists' command.
- * My card accepts a buffer config of 4/4.
- *
- * Setting the SAV BP bit does not save bad packets, but
- * only enables RX on-card stats collection.
- *
- * The documentation in places seems to miss things. In actual fact
- * I've always eventually found everything is documented, it just
- * requires careful study.
- *
- * DOC: Theory Of Operation
- *
- * The 3com 3c527 is a 32bit MCA bus mastering adapter with a large
- * amount of on board intelligence that housekeeps a somewhat dumber
- * Intel NIC. For performance we want to keep the transmit queue deep
- * as the card can transmit packets while fetching others from main
- * memory by bus master DMA. Transmission and reception are driven by
- * circular buffer queues.
- *
- * The mailboxes can be used for controlling how the card traverses
- * its buffer rings, but are used only for initial setup in this
- * implementation. The exec mailbox allows a variety of commands to
- * be executed. Each command must complete before the next is
- * executed. Primarily we use the exec mailbox for controlling the
- * multicast lists. We have to do a certain amount of interesting
- * hoop jumping as the multicast list changes can occur in interrupt
- * state when the card has an exec command pending. We defer such
- * events until the command completion interrupt.
- *
- * A copy break scheme (taken from 3c59x.c) is employed whereby
- * received frames exceeding a configurable length are passed
- * directly to the higher networking layers without incuring a copy,
- * in what amounts to a time/space trade-off.
- *
- * The card also keeps a large amount of statistical information
- * on-board. In a perfect world, these could be used safely at no
- * cost. However, lacking information to the contrary, processing
- * them without races would involve so much extra complexity as to
- * make it unworthwhile to do so. In the end, a hybrid SW/HW
- * implementation was made necessary --- see mc32_update_stats().
- *
- * DOC: Notes
- *
- * It should be possible to use two or more cards, but at this stage
- * only by loading two copies of the same module.
- *
- * The on-board 82586 NIC has trouble receiving multiple
- * back-to-back frames and so is likely to drop packets from fast
- * senders.

+ * The 82599 and the X540 do not have true 64bit nanosecond scale
+ * counter registers. Instead, SYSTIME is defined by a fixed point
+ * system which allows the user to define the scale counter increment
+ * value at every level change of the oscillator driving the SYSTIME
+ * value. For both devices the TIMINCA:IV field defines this
+ * increment. On the X540 device, 31 bits are provided. However on the
+ * 82599 only provides 24 bits. The time unit is determined by the
+ * clock frequency of the oscillator in combination with the TIMINCA
+ * register. When these devices link at 10Gb the oscillator has a
+ * period of 6.4ns. In order to convert the scale counter into
+ * nanoseconds the cyclecounter and timecounter structures are
+ * used. The SYSTIME registers need to be converted to ns values by use
+ * of only a right shift (division by power of 2). The following math
+ * determines the largest incvalue that will fit into the available
+ * bits in the TIMINCA register.
+ *
+ * PeriodWidth: Number of bits to store the clock period
+ * MaxWidth: The maximum width value of the TIMINCA register
+ * Period: The clock period for the oscillator
+ * round(): discard the fractional portion of the calculation
+ *
+ * Period * [ 2 ^ ( MaxWidth - PeriodWidth ) ]
+ *
+ * For the X540, MaxWidth is 31 bits, and the base period is 6.4 ns
+ * For the 82599, MaxWidth is 24 bits, and the base period is 6.4 ns
+ *
+ * The period also changes based on the link speed:
+ * At 10Gb link or no link, the period remains the same.
+ * At 1Gb link, the period is multiplied by 10. (64ns)
+ * At 100Mb link, the period is multiplied by 100. (640ns)
+ *
+ * The calculated value allows us to right shift the SYSTIME register
+ * value in order to quickly convert it into a nanosecond clock,
+ * while allowing for the maximum possible adjustment value.
+ *
+ * These diagrams are only for the 10Gb link period

- To compile this driver as a module, choose M here. The only

- *
- * Assumptions made in this code:
- * - The IXP2400 MSF is configured for POS-PHY mode, in a mode where
- * only one full element list is used. This includes, for example,
- * 1x32 SPHY and 1x32 MPHY32, but not 4x8 SPHY or 1x32 MPHY4. (This
- * is not an exhaustive list.)
- * - The RBUF uses 64-byte mpackets.
- * - RX descriptors reside in SRAM, and have the following format:
- * struct rx_desc
- * {
- * // to uengine
- * u32 buf_phys_addr;
- * u32 buf_length;
- *
- * // from uengine
- * u32 channel;
- * u32 pkt_length;
- * };
- * - Packet data resides in DRAM.
- * - Packet buffer addresses are 8-byte aligned.
- * - Scratch ring 0 is rx_pending.
- * - Scratch ring 1 is rx_done, and has status condition 'full'.
- * - The host triggers rx_done flush and rx_pending refill on seeing INTA.
- * - This code is run on all eight threads of the microengine it runs on.
- *
- * Local memory is used for per-channel RX state.

- * Assumptions made in this code:
- * - The IXP2400 MSF is configured for POS-PHY mode, in a mode where
- * only one TBUF partition is used. This includes, for example,
- * 1x32 SPHY and 1x32 MPHY32, but not 4x8 SPHY or 1x32 MPHY4. (This
- * is not an exhaustive list.)
- * - The TBUF uses 64-byte mpackets.
- * - TX descriptors reside in SRAM, and have the following format:
- * struct tx_desc
- * {
- * // to uengine
- * u32 buf_phys_addr;
- * u32 pkt_length;
- * u32 channel;
- * };
- * - Packet data resides in DRAM.
- * - Packet buffer addresses are 8-byte aligned.
- * - Scratch ring 2 is tx_pending.
- * - Scratch ring 3 is tx_done, and has status condition 'full'.
- * - This code is run on all eight threads of the microengine it runs on.

- * Technical Card Details
- *
- * All access to data is done with 16/8 bit transfers. The transfer
- * method really sucks. You can only read or write one location at a time.
- *
- * Also, the microcode for the card must be uploaded if the card does not have
- * the flashrom on board. This is a 28K bloat in the driver when compiled
- * as a module.
- *
- * Rx is very simple, status into a ring of descriptors, dma data transfer,
- * interrupts to tell us when a packet is received.
- *
- * Tx is a little more interesting. Similar scenario, descriptor and dma data
- * transfers, but we don't have to interrupt the card to tell it another packet
- * is ready for transmission, we are just doing simple memory writes, not io or mmio
- * writes. The card can be set up to simply poll on the next
- * descriptor pointer and when this value is non-zero will automatically download
- * the next packet. The card then interrupts us when the packet is done.

- * available descriptor and keeps reading the next_ptr until next_ptr is set

- * position to 0, therefore making the current position the last position on the ring.
- * The last position on the ring therefore loops continually loops around the rx ring.
- *
- * rx_ring_tail is the position on the ring to process next. (Think of a snake, the head
- * expands as the card adds new packets and we go around eating the tail processing the
- * packets.)

-/* ibmtr.c: A shared-memory IBM Token Ring 16/4 driver for linux
- *
- * Written 1993 by Mark Swanson and Peter De Schrijver.
- * This software may be used and distributed according to the terms
- * of the GNU General Public License, incorporated herein by reference.
- *
- * This device driver should work with Any IBM Token Ring Card that does
- * not use DMA.
- *
- * I used Donald Becker's (becker@scyld.com) device driver work
- * as a base for most of my initial work.
- *
- * Changes by Peter De Schrijver
- * (Peter.Deschrijver@linux.cc.kuleuven.ac.be) :
- *
- * + changed name to ibmtr.c in anticipation of other tr boards.
- * + changed reset code and adapter open code.
- * + added SAP open code.
- * + a first attempt to write interrupt, transmit and receive routines.
- *
- * Changes by David W. Morris (dwm@shell.portal.com) :
- * 941003 dwm: - Restructure tok_probe for multiple adapters, devices.
- * + Add comments, misc reorg for clarity.
- * + Flatten interrupt handler levels.
- *
- * Changes by Farzad Farid (farzy@zen.via.ecp.fr)
- * and Pascal Andre (andre@chimay.via.ecp.fr) (March 9 1995) :
- * + multi ring support clean up.
- * + RFC1042 compliance enhanced.
- *
- * Changes by Pascal Andre (andre@chimay.via.ecp.fr) (September 7 1995) :
- * + bug correction in tr_tx
- * + removed redundant information display
- * + some code reworking
- *
- * Changes by Michel Lespinasse (walken@via.ecp.fr),
- * Yann Doussot (doussot@via.ecp.fr) and Pascal Andre (andre@via.ecp.fr)
- * (February 18, 1996) :
- * + modified shared memory and mmio access port the driver to
- * alpha platform (structure access -> readb/writeb)
- *
- * Changes by Steve Kipisz (bungy@ibm.net or kipisz@vnet.ibm.com)
- * (January 18 1996):
- * + swapped WWOR and WWCR in ibmtr.h
- * + moved some init code from tok_probe into trdev_init. The
- * PCMCIA code can call trdev_init to complete initializing
- * the driver.
- * + added -DPCMCIA to support PCMCIA
- * + detecting PCMCIA Card Removal in interrupt handler. If
- * ISRP is FF, then a PCMCIA card has been removed
- * 10/2000 Burt needed a new method to avoid crashing the OS
- *
- * Changes by Paul Norton (pnorton@cts.com) :
- * + restructured the READ.LOG logic to prevent the transmit SRB
- * from being rudely overwritten before the transmit cycle is
- * complete. (August 15 1996)
- * + completed multiple adapter support. (November 20 1996)
- * + implemented csum_partial_copy in tr_rx and increased receive
- * buffer size and count. Minor fixes. (March 15, 1997)
- *
- * Changes by Christopher Turcksin <wabbit@rtfc.demon.co.uk>
- * + Now compiles ok as a module again.
- *
- * Changes by Paul Norton (pnorton@ieee.org) :
- * + moved the header manipulation code in tr_tx and tr_rx to
- * net/802/tr.c. (July 12 1997)
- * + add retry and timeout on open if cable disconnected. (May 5 1998)
- * + lifted 2000 byte mtu limit. now depends on shared-RAM size.
- * May 25 1998)
- * + can't allocate 2k recv buff at 8k shared-RAM. (20 October 1998)
- *
- * Changes by Joel Sloan (jjs@c-me.com) :
- * + disable verbose debug messages by default - to enable verbose
- * debugging, edit the IBMTR_DEBUG_MESSAGES define below
- *
- * Changes by Mike Phillips <phillim@amtrak.com> :
- * + Added extra #ifdef's to work with new PCMCIA Token Ring Code.
- * The PCMCIA code now just sets up the card so it can be recognized
- * by ibmtr_probe. Also checks allocated memory vs. on-board memory
- * for correct figure to use.
- *
- * Changes by Tim Hockin (thockin@isunix.it.ilstu.edu) :
- * + added spinlocks for SMP sanity (10 March 1999)
- *
- * Changes by Jochen Friedrich to enable RFC1469 Option 2 multicasting
- * i.e. using functional address C0 00 00 04 00 00 to transmit and
- * receive multicast packets.
- *
- * Changes by Mike Sullivan (based on original sram patch by Dave Grothe
- * to support windowing into on adapter shared ram.
- * i.e. Use LANAID to setup a PnP configuration with 16K RAM. Paging
- * will shift this 16K window over the entire available shared RAM.
- *
- * Changes by Peter De Schrijver (p2@mind.be) :
- * + fixed a problem with PCMCIA card removal
- *
- * Change by Mike Sullivan et al.:
- * + added turbo card support. No need to use lanaid to configure
- * the adapter into isa compatibility mode.
- *
- * Changes by Burt Silverman to allow the computer to behave nicely when
- * a cable is pulled or not in place, or a PCMCIA card is removed hot.

-/*======================================================================
-
- A PCMCIA token-ring driver for IBM-based cards
-
- This driver supports the IBM PCMCIA Token-Ring Card.
- Written by Steve Kipisz, kipisz@vnet.ibm.com or
- bungy@ibm.net
-
- Written 1995,1996.
-
- This code is based on pcnet_cs.c from David Hinds.
-
- V2.2.0 February 1999 - Mike Phillips phillim@amtrak.com
-
- Linux V2.2.x presented significant changes to the underlying
- ibmtr.c code. Mainly the code became a lot more organized and
- modular.
-
- This caused the old PCMCIA Token Ring driver to give up and go
- home early. Instead of just patching the old code to make it
- work, the PCMCIA code has been streamlined, updated and possibly
- improved.
-
- This code now only contains code required for the Card Services.
- All we do here is set the card up enough so that the real ibmtr.c
- driver can find it and work with it properly.
-
- i.e. We set up the io port, irq, mmio memory and shared ram
- memory. This enables ibmtr_probe in ibmtr.c to find the card and
- configure it as though it was a normal ISA and/or PnP card.
-
- CHANGES
-
- v2.2.5 April 1999 Mike Phillips (phillim@amtrak.com)
- Obscure bug fix, required changed to ibmtr.c not ibmtr_cs.c
-
- v2.2.7 May 1999 Mike Phillips (phillim@amtrak.com)
- Updated to version 2.2.7 to match the first version of the kernel
- that the modification to ibmtr.c were incorporated into.
-
- v2.2.17 July 2000 Burt Silverman (burts@us.ibm.com)
- Address translation feature of PCMCIA controller is usable so
- memory windows can be placed in High memory (meaning above
- 0xFFFFF.)

- *
- * 12/10/99 - Alpha Release 0.1.0
- * First release to the public
- * 03/03/00 - Merged to kernel, indented -kr -i8 -bri0, fixed some missing
- * malloc free checks, reviewed code. <alan@redhat.com>
- * 03/13/00 - Added spinlocks for smp
- * 03/08/01 - Added support for module_init() and module_exit()
- * 08/15/01 - Added ioctl() functionality for debugging, changed netif_*_queue
- * calls and other incorrectness - Kent Yoder <yoder1@us.ibm.com>
- * 11/05/01 - Restructured the interrupt function, added delays, reduced the
- * the number of TX descriptors to 1, which together can prevent
- * the card from locking up the box - <yoder1@us.ibm.com>
- * 09/27/02 - New PCI interface + bug fix. - <yoder1@us.ibm.com>
- * 11/13/02 - Removed free_irq calls which could cause a hang, added
- * netif_carrier_{on|off} - <yoder1@us.ibm.com>
- *
- * To Do:
- *
- *
- * If Problems do Occur
- * Most problems can be rectified by either closing and opening the interface
- * (ifconfig down and up) or rmmod and insmod'ing the driver (a bit difficult
- * if compiled into the kernel).

- * Handle interrupts generated by the card
- *
- * The MicroChannel Madge cards need slightly more handling
- * after an interrupt than other TMS380 cards do.
- *
- * First we must make sure it was this card that generated the
- * interrupt (since interrupt sharing is allowed). Then,
- * because we're using level-triggered interrupts (as is
- * standard on MCA), we must toggle the interrupt line
- * on the card in order to claim and acknowledge the interrupt.
- * Once that is done, the interrupt should be handlable in
- * the normal tms380tr_interrupt() routine.
- *
- * There's two ways we can check to see if the interrupt is ours,
- * both with their own disadvantages...
- *
- * 1) Read in the SIFSTS register from the TMS controller. This
- * is guaranteed to be accurate, however, there's a fairly
- * large performance penalty for doing so: the Madge chips
- * must request the register from the Eagle, the Eagle must
- * read them from its internal bus, and then take the route
- * back out again, for a 16bit read.
- *
- * 2) Use the MC_CONTROL_REG0_SINTR bit from the Madge ASICs.
- * The major disadvantage here is that the accuracy of the
- * bit is in question. However, it cuts out the extra read
- * cycles it takes to read the Eagle's SIF, as its only an
- * 8bit read, and theoretically the Madge bit is directly
- * connected to the interrupt latch coming out of the Eagle
- * hardware (that statement is not verified).
- *
- * I can't determine which of these methods has the best win. For now,
- * we make a compromise. Use the Madge way for the first interrupt,
- * which should be the fast-path, and then once we hit the first
- * interrupt, keep on trying using the SIF method until we've
- * exhausted all contiguous interrupts.

- * 1999/2000 Mike Phillips (mikep@linuxtr.net)
- *
- * Linux driver for IBM PCI tokenring cards based on the Pit/Pit-Phy/Olympic
- * chipset.
- *
- * Base Driver Skeleton:
- * Written 1993-94 by Donald Becker.
- *
- * Copyright 1993 United States Government as represented by the
- * Director, National Security Agency.
- *
- * Thanks to Erik De Cock, Adrian Bridgett and Frank Fiene for their
- * assistance and perserverance with the testing of this driver.
- *
- * This software may be used and distributed according to the terms
- * of the GNU General Public License, incorporated herein by reference.
- *
- * 4/27/99 - Alpha Release 0.1.0
- * First release to the public
- *
- * 6/8/99 - Official Release 0.2.0
- * Merged into the kernel code
- * 8/18/99 - Updated driver for 2.3.13 kernel to use new pci
- * resource. Driver also reports the card name returned by
- * the pci resource.
- * 1/11/00 - Added spinlocks for smp
- * 2/23/00 - Updated to dev_kfree_irq
- * 3/10/00 - Fixed FDX enable which triggered other bugs also
- * squashed.
- * 5/20/00 - Changes to handle Olympic on LinuxPPC. Endian changes.
- * The odd thing about the changes is that the fix for
- * endian issues with the big-endian data in the arb, asb...
- * was to always swab() the bytes, no matter what CPU.
- * That's because the read[wl]() functions always swap the
- * bytes on the way in on PPC.
- * Fixing the hardware descriptors was another matter,
- * because they weren't going through read[wl](), there all
- * the results had to be in memory in le32 values. kdaaker
- *
- * 12/23/00 - Added minimal Cardbus support (Thanks Donald).
- *
- * 03/09/01 - Add new pci api, dev_base_lock, general clean up.
- *
- * 03/27/01 - Add new dma pci (Thanks to Kyle Lucke) and alloc_trdev
- * Change proc_fs behaviour, now one entry per adapter.
- *
- * 04/09/01 - Couple of bug fixes to the dma unmaps and ejecting the
- * adapter when live does not take the system down with it.
- *
- * 06/02/01 - Clean up, copy skb for small packets
- *
- * 06/22/01 - Add EISR error handling routines
- *
- * 07/19/01 - Improve bad LAA reporting, strip out freemem
- * into a separate function, its called from 3
- * different places now.
- * 02/09/02 - Replaced sleep_on.
- * 03/01/02 - Replace access to several registers from 32 bit to
- * 16 bit. Fixes alignment errors on PPC 64 bit machines.
- * Thanks to Al Trautman for this one.
- * 03/10/02 - Fix BUG in arb_cmd. Bug was there all along but was
- * silently ignored until the error checking code
- * went into version 1.0.0
- * 06/04/02 - Add correct start up sequence for the cardbus adapters.
- * Required for strict compliance with pci power mgmt specs.
- * To Do:
- *
- * Wake on lan
- *
- * If Problems do Occur
- * Most problems can be rectified by either closing and opening the interface
- * (ifconfig down and up) or rmmod and insmod'ing the driver (a bit difficult
- * if compiled into the kernel).

-/*
- * tms380tr.c: A network driver library for Texas Instruments TMS380-based
- * Token Ring Adapters.
- *
- * Originally sktr.c: Written 1997 by Christoph Goos
- *
- * A fine result of the Linux Systems Network Architecture Project.
- * http://www.vanheusden.com/sna/
- *
- * This software may be used and distributed according to the terms
- * of the GNU General Public License, incorporated herein by reference.
- *
- * The following modules are currently available for card support:
- * - tmspci (Generic PCI card support)
- * - abyss (Madge PCI support)
- * - tmsisa (SysKonnect TR4/16 ISA)
- *
- * Sources:
- * - The hardware related parts of this driver are take from
- * the SysKonnect Token Ring driver for Windows NT.
- * - I used the IBM Token Ring driver 'ibmtr.c' as a base for this
- * driver, as well as the 'skeleton.c' driver by Donald Becker.
- * - Also various other drivers in the linux source tree were taken
- * as samples for some tasks.
- * - TI TMS380 Second-Generation Token Ring User's Guide
- * - TI datasheets for respective chips
- * - David Hein at Texas Instruments
- * - Various Madge employees
- *
- * Maintainer(s):
- * JS Jay Schulist jschlst@samba.org
- * CG Christoph Goos cgoos@syskonnect.de
- * AF Adam Fritzler
- * MLP Mike Phillips phillim@amtrak.com
- * JF Jochen Friedrich jochen@scram.de
- *
- * Modification History:
- * 29-Aug-97 CG Created
- * 04-Apr-98 CG Fixed problems caused by tok_timer_check
- * 10-Apr-98 CG Fixed lockups at cable disconnection
- * 27-May-98 JS Formated to Linux Kernel Format
- * 31-May-98 JS Hacked in PCI support
- * 16-Jun-98 JS Modulized for multiple cards with one driver
- * Sep-99 AF Renamed to tms380tr (supports more than SK's)
- * 23-Sep-99 AF Added Compaq and Thomas-Conrad PCI support
- * Fixed a bug causing double copies on PCI
- * Fixed for new multicast stuff (2.2/2.3)
- * 25-Sep-99 AF Uped TPL_NUM from 3 to 9
- * Removed extraneous 'No free TPL'
- * 22-Dec-99 AF Added Madge PCI Mk2 support and generalized
- * parts of the initilization procedure.
- * 30-Dec-99 AF Turned tms380tr into a library ala 8390.
- * Madge support is provided in the abyss module
- * Generic PCI support is in the tmspci module.
- * 30-Nov-00 JF Updated PCI code to support IO MMU via
- * pci_map_static(). Alpha uses this MMU for ISA
- * as well.
- * 14-Jan-01 JF Fix DMA on ifdown/ifup sequences. Some
- * cleanup.
- * 13-Jan-02 JF Add spinlock to fix race condition.
- * 09-Nov-02 JF Fixed printks to not SPAM the console during
- * normal operation.
- * 30-Dec-02 JF Removed incorrect __init from
- * tms380tr_init_card.
- * 22-Jul-05 JF Converted to dma-mapping.
- *
- * To do:
- * 1. Multi/Broadcast packet handling (this may have fixed itself)
- * 2. Write a sktrisa module that includes the old ISA support (done)
- * 3. Allow modules to load their own microcode
- * 4. Speed up the BUD process -- freezing the kernel for 3+sec is
- * quite unacceptable.
- * 5. Still a few remaining stalls when the cable is unplugged.

-/**
- * DOC: shared area - role and goal
- *
- * The shared area contains all the data exported by the upper layer to the
- * other layers. Since the bus and transport layer shouldn't dereference
- * iwl_priv, all the data needed by the upper layer and the transport / bus
- * layer must be here.
- * The shared area also holds pointer to all the other layers. This allows a
- * layer to call a function from another layer.
- *
- * NOTE: All the layers hold a pointer to the shared area which must be shrd.
- * A few macros assume that (_m)->shrd points to the shared area no matter
- * what _m is.
- *
- * gets notifications about enumeration, suspend, resume.
- * For the moment, the bus layer is not a linux kernel module as itself, and
- * the module_init function of the driver must call the bus specific
- * registration functions. These functions are listed at the end of this file.
- * For the moment, there is only one implementation of this interface: PCI-e.
- * This implementation is iwl-pci.c

/**
+ * DOC: HW queue control
+ *
+ * Before HW queue control was introduced, mac80211 only had a single static
+ * assignment of per-interface AC software queues to hardware queues. This
+ * was problematic for a few reasons:
+ * 1) off-channel transmissions might get stuck behind other frames
+ * 2) multiple virtual interfaces couldn't be handled correctly
+ * 3) after-DTIM frames could get stuck behind other frames
+ *
+ * To solve this, hardware typically uses multiple different queues for all
+ * the different usages, and this needs to be propagated into mac80211 so it
+ * won't have the same problem with the software queues.
+ *
+ * Therefore, mac80211 now offers the %IEEE80211_HW_QUEUE_CONTROL capability
+ * flag that tells it that the driver implements its own queue control. To do
+ * so, the driver will set up the various queues in each &struct ieee80211_vif
+ * and the offchannel queue in &struct ieee80211_hw. In response, mac80211 will
+ * use those queue IDs in the hw_queue field of &struct ieee80211_tx_info and
+ * if necessary will queue the frame on the right software queue that mirrors
+ * the hardware queue.
+ * Additionally, the driver has to then use these HW queue IDs for the queue
+ * management functions (ieee80211_stop_queue() et al.)
+ *
+ * The driver is free to set up the queue mappings as needed, multiple virtual
+ * interfaces may map to the same hardware queues if needed. The setup has to
+ * happen during add_interface or change_interface callbacks. For example, a
+ * driver supporting station+station and station+AP modes might decide to have
+ * 10 hardware queues to handle different scenarios:
+ *
+ * 4 AC HW queues for 1st vif: 0, 1, 2, 3
+ * 4 AC HW queues for 2nd vif: 4, 5, 6, 7
+ * after-DTIM queue for AP: 8
+ * off-channel queue: 9
+ *
+ * It would then set up the hardware like this:
+ * hw.offchannel_tx_hw_queue = 9
+ *
+ * and the first virtual interface that is added as follows:
+ * vif.hw_queue[IEEE80211_AC_VO] = 0
+ * vif.hw_queue[IEEE80211_AC_VI] = 1
+ * vif.hw_queue[IEEE80211_AC_BE] = 2
+ * vif.hw_queue[IEEE80211_AC_BK] = 3
+ * vif.cab_queue = 8 // if AP mode, otherwise %IEEE80211_INVAL_HW_QUEUE
+ * and the second virtual interface with 4-7.
+ *
+ * If queue 6 gets full, for example, mac80211 would only stop the second
+ * virtual interface's BE queue since virtual interface queues are per AC.
+ *
+ * Note that the vif.cab_queue value should be set to %IEEE80211_INVAL_HW_QUEUE
+ * whenever the queue is not used (i.e. the interface is not in AP mode) if the
+ * queue could potentially be shared since mac80211 will look at cab_queue when
+ * a queue is stopped/woken even if the interface is not in AP mode.

- ---help---
- Econet is a fairly old and slow networking protocol mainly used by
- Acorn computers to access file and print servers. It uses native
- Econet network cards. AUN is an implementation of the higher level
- parts of Econet that runs over ordinary Ethernet connections, on
- top of the UDP packet protocol, which in turn runs on top of the
- Internet protocol IP.
-
- If you say Y here, you can choose with the next two options whether
- to send Econet/AUN traffic over a UDP Ethernet connection or over

+
+ The target allows you to create rules in the "raw" and "mangle" tables
+ which set the skbuff mark by means of hash calculation within a given

+ change their behaviour.
+
+ To compile it as a module, choose M here. If unsure, say N.
