+ BestComm is the name of the communication coprocessor found
+ on the Freescale MPC5200 family of processor. Its usage is
+ optional for some drivers (like ATA), but required for
+ others (like FEC).
+
+ If you want to use drivers that require DMA operations,
+ answer Y or M. Otherwise say N.

+. Where should we do eviction (detatch_pages())? We aren't necessarily
+ accessing the pages via a GART, so maybe we need some other threshold
+ to put a cap on the # of pages that can be pin'd.
+ . Use mm_shrinker to trigger unpinning pages.
+ . This is mainly theoretical since most of these devices don't actually
+ have swap or harddrive.
+. GEM/shmem backed pages can have existing mappings (kernel linear map,
+ etc..), which isn't really ideal.
+. Revisit GEM sync object infrastructure.. TTM has some framework for this
+ already. Possibly this could be refactored out and made more common?
+ There should be some way to do this with less wheel-reinvention.
+ . This can be handled by the dma-buf fence/reservation stuff when it
+ lands

- Choose this option if you want kernel modesetting enabled by default.
+ Choose this option if you still need userspace modesetting.
- This is a completely new driver. It's only part of the existing drm
- for compatibility reasons. It requires an entirely different graphics
- stack above it and works very differently from the old drm stack.
- i.e. don't enable this unless you know what you are doing it may
- cause issues or bugs compared to the previous userspace driver stack.
-
- When kernel modesetting is enabled the IOCTL of radeon/drm
- driver are considered as invalid and an error message is printed
- in the log and they return failure.
-
- KMS enabled userspace will use new API to talk with the radeon/drm
- driver. The new API provide functions to create/destroy/share/mmap
- buffer object which are then managed by the kernel memory manager
- (here TTM). In order to submit command to the GPU the userspace
- provide a buffer holding the command stream, along this buffer
- userspace have to provide a list of buffer object used by the
- command stream. The kernel radeon driver will then place buffer
- in GPU accessible memory and will update command stream to reflect
- the position of the different buffers.
-
- The kernel will also perform security check on command stream
- provided by the user, we want to catch and forbid any illegal use
- of the GPU such as DMA into random system memory or into memory
- not owned by the process supplying the command stream.
+ Userspace modesetting is deprecated for quite some time now, so
+ enable this only if you have ancient versions of the DDX drivers.

/*
- Changes:
- 24.08.2002
- Fixed the typo in sis630_access (Thanks to Mark M. Hoffman)
- Changed sis630_transaction.(Thanks to Mark M. Hoffman)
- 18.09.2002
- Added SIS730 as supported.
- 21.09.2002
- Added high_clock module option.If this option is set
- used Host Master Clock 56KHz (default 14KHz).For now we save old Host
- Master Clock and after transaction completed restore (otherwise
- it's confuse BIOS and hung Machine).
- 24.09.2002
- Fixed typo in sis630_access
- Fixed logical error by restoring of Host Master Clock
- 31.07.2003
- Added block data read/write support.

+ | SMB_COUNT | 4:0 bits | 5:0 bits |
+ +------------------------+--------------------+-------------------+
+ (Other differences don't affect the functions provided by the driver)
Note: we assume there can only be one device, with one SMBus interface.

+ *
+ * o There is one CPU Interface per CPU, which sends interrupts sent
+ * by the Distributor, and interrupts generated locally, to the
+ * associated CPU. The base address of the CPU interface is usually
+ * aliased so that the same address points to different chips depending
+ * on the CPU it is accessed from.
+ *
+ * Note that IRQs 0-31 are special - they are local to each CPU.
+ * As such, the enable set/clear, pending set/clear and active bit
+ * registers are banked per-cpu for these sources.

+ * In the following, we will distinguish between two kinds of VMX processes -
+ * the ones with versions lower than VMCI_VERSION_NOVMVM that use specialized
+ * VMCI page files in the VMX and supporting VM to VM communication and the
+ * newer ones that use the guest memory directly. We will in the following
+ * refer to the older VMX versions as old-style VMX'en, and the newer ones as
+ * new-style VMX'en.
+ *
+ * The state transition datagram is as follows (the VMCIQPB_ prefix has been
+ * removed for readability) - see below for more details on the transtions:
+ *
+ * -------------- NEW -------------
+ * | |
+ * \_/ \_/
+ * CREATED_NO_MEM <-----------------> CREATED_MEM
+ * | | |
+ * | o-----------------------o |
+ * | | |
+ * \_/ \_/ \_/
+ * ATTACHED_NO_MEM <----------------> ATTACHED_MEM
+ * | | |
+ * | o----------------------o |
+ * | | |
+ * \_/ \_/ \_/
+ * SHUTDOWN_NO_MEM <----------------> SHUTDOWN_MEM
+ * | |
+ * | |
+ * -------------> gone <-------------
+ *
+ * In more detail. When a VMCI queue pair is first created, it will be in the
+ * VMCIQPB_NEW state. It will then move into one of the following states:
+ *
+ * - VMCIQPB_CREATED_NO_MEM: this state indicates that either:
+ *
+ * - the created was performed by a host endpoint, in which case there is
+ * no backing memory yet.
+ *
+ * - the create was initiated by an old-style VMX, that uses
+ * vmci_qp_broker_set_page_store to specify the UVAs of the queue pair at
+ * a later point in time. This state can be distinguished from the one
+ * above by the context ID of the creator. A host side is not allowed to
+ * attach until the page store has been set.
+ *
+ * - VMCIQPB_CREATED_MEM: this state is the result when the queue pair
+ * is created by a VMX using the queue pair device backend that
+ * sets the UVAs of the queue pair immediately and stores the
+ * information for later attachers. At this point, it is ready for
+ * the host side to attach to it.
+ *
+ * Once the queue pair is in one of the created states (with the exception of
+ * the case mentioned for older VMX'en above), it is possible to attach to the
+ * queue pair. Again we have two new states possible:
+ *
+ * - VMCIQPB_ATTACHED_MEM: this state can be reached through the following
+ * paths:
+ *
+ * - from VMCIQPB_CREATED_NO_MEM when a new-style VMX allocates a queue
+ * pair, and attaches to a queue pair previously created by the host side.
+ *
+ * - from VMCIQPB_CREATED_MEM when the host side attaches to a queue pair
+ * already created by a guest.
+ *
+ * - from VMCIQPB_ATTACHED_NO_MEM, when an old-style VMX calls
+ * vmci_qp_broker_set_page_store (see below).
+ *
+ * - VMCIQPB_ATTACHED_NO_MEM: If the queue pair already was in the
+ * VMCIQPB_CREATED_NO_MEM due to a host side create, an old-style VMX will
+ * bring the queue pair into this state. Once vmci_qp_broker_set_page_store
+ * is called to register the user memory, the VMCIQPB_ATTACH_MEM state
+ * will be entered.
+ *
+ * From the attached queue pair, the queue pair can enter the shutdown states
+ * when either side of the queue pair detaches. If the guest side detaches
+ * first, the queue pair will enter the VMCIQPB_SHUTDOWN_NO_MEM state, where
+ * the content of the queue pair will no longer be available. If the host
+ * side detaches first, the queue pair will either enter the
+ * VMCIQPB_SHUTDOWN_MEM, if the guest memory is currently mapped, or
+ * VMCIQPB_SHUTDOWN_NO_MEM, if the guest memory is not mapped
+ * (e.g., the host detaches while a guest is stunned).
+ *
+ * New-style VMX'en will also unmap guest memory, if the guest is
+ * quiesced, e.g., during a snapshot operation. In that case, the guest
+ * memory will no longer be available, and the queue pair will transition from
+ * *_MEM state to a *_NO_MEM state. The VMX may later map the memory once more,
+ * in which case the queue pair will transition from the *_NO_MEM state at that
+ * point back to the *_MEM state. Note that the *_NO_MEM state may have changed,
+ * since the peer may have either attached or detached in the meantime. The
+ * values are laid out such that ++ on a state will move from a *_NO_MEM to a
+ * *_MEM state, and vice versa.

- This is a device driver for the 3Com Etherlink 3c501.
- Do not purchase this card, even as a joke. It's performance is horrible,
- and it breaks in many ways.

- Fixed (again!) the missing interrupt locking on TX/RX shifting.
- Alan Cox <alan@lxorguk.ukuu.org.uk>
-
- Removed calls to init_etherdev since they are no longer needed, and
- cleaned up modularization just a bit. The driver still allows only
- the default address for cards when loaded as a module, but that's
- really less braindead than anyone using a 3c501 board. :)
- 19950208 (invid@msen.com)
-
- Added traps for interrupts hitting the window as we clear and TX load
- the board. Now getting 150K/second FTP with a 3c501 card. Still playing
- with a TX-TX optimisation to see if we can touch 180-200K/second as seems
- theoretically maximum.
- 19950402 Alan Cox <alan@lxorguk.ukuu.org.uk>

- Cleaned up for 2.3.x because we broke SMP now.

- * DOC: 3c501 Card Notes
- *
- * Some notes on this thing if you have to hack it. [Alan]
- *
- * Some documentation is available from 3Com. Due to the boards age
- * standard responses when you ask for this will range from 'be serious'
- * to 'give it to a museum'. The documentation is incomplete and mostly
- * of historical interest anyway.
- *
- * The basic system is a single buffer which can be used to receive or
- * transmit a packet. A third command mode exists when you are setting
- * things up.
- *
- * If it's transmitting it's not receiving and vice versa. In fact the
- * time to get the board back into useful state after an operation is
- * quite large.
- *
- * The driver works by keeping the board in receive mode waiting for a
- * packet to arrive. When one arrives it is copied out of the buffer
- * and delivered to the kernel. The card is reloaded and off we go.
- *
- * When transmitting lp->txing is set and the card is reset (from
- * receive mode) [possibly losing a packet just received] to command
- * mode. A packet is loaded and transmit mode triggered. The interrupt
- * handler runs different code for transmit interrupts and can handle
- * returning to receive mode or retransmissions (yes you have to help
- * out with those too).
- *
- * DOC: Problems
- *
- * There are a wide variety of undocumented error returns from the card
- * and you basically have to kick the board and pray if they turn up. Most
- * only occur under extreme load or if you do something the board doesn't
- * like (eg touching a register at the wrong time).
- *
- * The driver is less efficient than it could be. It switches through
- * receive mode even if more transmits are queued. If this worries you buy
- * a real Ethernet card.
- *
- * The combination of slow receive restart and no real multicast
- * filter makes the board unusable with a kernel compiled for IP
- * multicasting in a real multicast environment. That's down to the board,
- * but even with no multicast programs running a multicast IP kernel is
- * in group 224.0.0.1 and you will therefore be listening to all multicasts.
- * One nv conference running over that Ethernet and you can give up.

-
- The E2100 series ethercard is a fairly generic shared memory 8390
- implementation. The only unusual aspect is the way the shared memory
- registers are set: first you do an inb() in what is normally the
- station address region, and the low three bits of next outb() *address*
- is used as the write value for that register. Either someone wasn't
- too used to dem bit en bites, or they were trying to obfuscate the
- programming interface.
-
- There is an additional complication when setting the window on the packet
- buffer. You must first do a read into the packet buffer region with the
- low 8 address bits the address setting the page for the start of the packet
- buffer window, and then do the above operation. See mem_on() for details.
-
- One bug on the chip is that even a hard reset won't disable the memory
- window, usually resulting in a hung machine if mem_off() isn't called.
- If this happens, you must power down the machine for about 30 seconds.

- es3210.c
-
- Linux driver for Racal-Interlan ES3210 EISA Network Adapter
-
- Copyright (C) 1996, Paul Gortmaker.
-
- This software may be used and distributed according to the terms
- of the GNU General Public License, incorporated herein by reference.
-
- Information and Code Sources:
-
- 1) The existing myriad of Linux 8390 drivers written by Donald Becker.
-
- 2) Once again Russ Nelson's asm packet driver provided additional info.
-
- 3) Info for getting IRQ and sh-mem gleaned from the EISA cfg files.
- Too bad it doesn't work -- see below.
-
- The ES3210 is an EISA shared memory NS8390 implementation. Note
- that all memory copies to/from the board must be 32bit transfers.
- Which rules out using eth_io_copy_and_sum() in this driver.
-
- Apparently there are two slightly different revisions of the
- card, since there are two distinct EISA cfg files (!rii0101.cfg
- and !rii0102.cfg) One has media select in the cfg file and the
- other doesn't. Hopefully this will work with either.
-
- That is about all I can tell you about it, having never actually
- even seen one of these cards. :) Try http://www.interlan.com
- if you want more info.
-
- Thanks go to Mark Salazar for testing v0.02 of this driver.
-
- Bugs, to-fix, etc:
-
- 1) The EISA cfg ports that are *supposed* to have the IRQ and shared
- mem values just read 0xff all the time. Hrrmpf. Apparently the
- same happens with the packet driver as the code for reading
- these registers is disabled there. In the meantime, boot with:
- ether=<IRQ>,0,0x<shared_mem_addr>,eth0 to override the IRQ and
- shared memory detection. (The i/o port detection is okay.)
-
- 2) Module support currently untested. Probably works though.

-/*
- The HP EtherTwist chip implementation is a fairly routine DP8390
- implementation. It allows both shared memory and programmed-I/O buffer
- access, using a custom interface for both. The programmed-I/O mode is
- entirely implemented in the HP EtherTwist chip, bypassing the problem
- ridden built-in 8390 facilities used on NE2000 designs. The shared
- memory mode is likewise special, with an offset register used to make
- packets appear at the shared memory base. Both modes use a base and bounds
- page register to hide the Rx ring buffer wrap -- a packet that spans the
- end of physical buffer memory appears continuous to the driver. (c.f. the
- 3c503 and Cabletron E2100)
-
- A special note: the internal buffer of the board is only 8 bits wide.
- This lays several nasty traps for the unaware:
- - the 8390 must be programmed for byte-wide operations
- - all I/O and memory operations must work on whole words (the access
- latches are serially preloaded and have no byte-swapping ability).
-
- This board is laid out in I/O space much like the earlier HP boards:
- the first 16 locations are for the board registers, and the second 16 are
- for the 8390. The board is easy to identify, with both a dedicated 16 bit
- ID register and a constant 0x530* value in the upper bits of the paging
- register.

-
- 1) Based upon framework of es3210 driver.
- 2) The existing myriad of other Linux 8390 drivers by Donald Becker.
- 3) Russ Nelson's asm packet driver provided additional info.
- 4) Info for getting IRQ and sh-mem gleaned from the EISA cfg files.
-
- The LNE390 is an EISA shared memory NS8390 implementation. Note
- that all memory copies to/from the board must be 32bit transfers.
- There are two versions of the card: the lne390a and the lne390b.
- Going by the EISA cfg files, the "a" has jumpers to select between
- BNC/AUI, but the "b" also has RJ-45 and selection is via the SCU.
- The shared memory address selection is also slightly different.
- Note that shared memory address > 1MB are supported with this driver.
-
- You can try <http://www.mylex.com> if you want more info, as I've
- never even seen one of these cards. :)
-

-
- This software may be used and distributed according to the terms

-
- Information and Code Sources:
-
- 1) Based upon my other EISA 8390 drivers (lne390, es3210, smc-ultra32)
- 2) The existing myriad of other Linux 8390 drivers by Donald Becker.
- 3) Info for getting IRQ and sh-mem gleaned from the EISA cfg file
-
- The NE3210 is an EISA shared memory NS8390 implementation. Shared
- memory address > 1MB should work with this driver.
-
- Note that the .cfg file (3/11/93, v1.0) has AUI and BNC switched
- around (or perhaps there are some defective/backwards cards ???)
-
- This driver WILL NOT WORK FOR THE NE3200 - it is completely different
- and does not use an 8390 at all.
-
- Updated to EISA probing API 5/2003 by Marc Zyngier.

-/* smc-ultra32.c: An SMC Ultra32 EISA ethernet driver for linux.
-
-Sources:
-
- This driver is based on (cloned from) the ISA SMC Ultra driver
- written by Donald Becker. Modifications to support the EISA
- version of the card by Paul Gortmaker and Leonard N. Zubkoff.
-
- This software may be used and distributed according to the terms
- of the GNU General Public License, incorporated herein by reference.
-
-Theory of Operation:
-
- The SMC Ultra32C card uses the SMC 83c790 chip which is also
- found on the ISA SMC Ultra cards. It has a shared memory mode of
- operation that makes it similar to the ISA version of the card.
- The main difference is that the EISA card has 32KB of RAM, but
- only an 8KB window into that memory. The EISA card also can be
- set for a bus-mastering mode of operation via the ECU, but that
- is not (and probably will never be) supported by this driver.
- The ECU should be run to enable shared memory and to disable the
- bus-mastering feature for use with linux.
-
- By programming the 8390 to use only 8KB RAM, the modifications
- to the ISA driver can be limited to the probe and initialization
- code. This allows easy integration of EISA support into the ISA
- driver. However, the driver development kit from SMC provided the
- register information for sliding the 8KB window, and hence the 8390
- is programmed to use the full 32KB RAM.
-
- Unfortunately this required code changes outside the probe/init
- routines, and thus we decided to separate the EISA driver from
- the ISA one. In this way, ISA users don't end up with a larger
- driver due to the EISA code, and EISA users don't end up with a
- larger driver due to the ISA EtherEZ PIO code. The driver is
- similar to the 3c503/16 driver, in that the window must be set
- back to the 1st 8KB of space for access to the two 8390 Tx slots.
-
- In testing, using only 8KB RAM (3 Tx / 5 Rx) didn't appear to
- be a limiting factor, since the EISA bus could get packets off
- the card fast enough, but having the use of lots of RAM as Rx
- space is extra insurance if interrupt latencies become excessive.

- This driver is written for the Digital Equipment Corporation series
- of DEPCA and EtherWORKS ethernet cards:

- DEPCA (the original)
- DE100
- DE101
- DE200 Turbo
- DE201 Turbo
- DE202 Turbo (TP BNC)
- DE210
- DE422 (EISA)
-
- The driver has been tested on DE100, DE200 and DE202 cards in a
- relatively busy network. The DE422 has been tested a little.
-
- This driver will NOT work for the DE203, DE204 and DE205 series of
- cards, since they have a new custom ASIC in place of the AMD LANCE
- chip. See the 'ewrk3.c' driver in the Linux source tree for running
- those cards.
-
- I have benchmarked the driver with a DE100 at 595kB/s to (542kB/s from)
- a DECstation 5000/200.

- The driver was originally based on the 'lance.c' driver from Donald
- Becker which is included with the standard driver distribution for

-
-
- Peter Bauer's depca.c (V0.5) was referred to when debugging V0.1 of this
- driver.
-
- The original DEPCA card requires that the ethernet ROM address counter
- be enabled to count and has an 8 bit NICSR. The ROM counter enabling is
- only done when a 0x08 is read as the first address octet (to minimise
- the chances of writing over some other hardware's I/O register). The
- NICSR accesses have been changed to byte accesses for all the cards
- supported by this driver, since there is only one useful bit in the MSB
- (remote boot timeout) and it is not used. Also, there is a maximum of
- only 48kB network RAM for this card. My thanks to Torbjorn Lindh for
- help debugging all this (and holding my feet to the fire until I got it
- right).
-
- The DE200 series boards have on-board 64kB RAM for use as a shared
- memory network buffer. Only the DE100 cards make use of a 2kB buffer
- mode which has not been implemented in this driver (only the 32kB and
- 64kB modes are supported [16kB/48kB for the original DEPCA]).
-
- At the most only 2 DEPCA cards can be supported on the ISA bus because
- there is only provision for two I/O base addresses on each card (0x300
- and 0x200). The I/O address is detected by searching for a byte sequence
- in the Ethernet station address PROM at the expected I/O address for the
- Ethernet PROM. The shared memory base address is 'autoprobed' by
- looking for the self test PROM and detecting the card name. When a
- second DEPCA is detected, information is placed in the base_addr
- variable of the next device structure (which is created if necessary),
- thus enabling ethif_probe initialization for the device. More than 2
- EISA cards can be supported, but care will be needed assigning the
- shared memory to ensure that each slot has the correct IRQ, I/O address
- and shared memory address assigned.
-
- ************************************************************************
-
- NOTE: If you are using two ISA DEPCAs, it is important that you assign
- the base memory addresses correctly. The driver autoprobes I/O 0x300
- then 0x200. The base memory address for the first device must be less
- than that of the second so that the auto probe will correctly assign the
- I/O and memory addresses on the same card. I can't think of a way to do
- this unambiguously at the moment, since there is nothing on the cards to
- tie I/O and memory information together.
-
- I am unable to test 2 cards together for now, so this code is
- unchecked. All reports, good or bad, are welcome.
-
- ************************************************************************
-
- The board IRQ setting must be at an unused IRQ which is auto-probed
- using Donald Becker's autoprobe routines. DEPCA and DE100 board IRQs are
- {2,3,4,5,7}, whereas the DE200 is at {5,9,10,11,15}. Note that IRQ2 is
- really IRQ9 in machines with 16 IRQ lines.
-
- No 16MB memory limitation should exist with this driver as DMA is not
- used and the common memory area is in low memory on the network card (my
- current system has 20MB and I've not had problems yet).
-
- The ability to load this driver as a loadable module has been added. To
- utilise this ability, you have to do <8 things:
-
- 0) have a copy of the loadable modules code installed on your system.
- 1) copy depca.c from the /linux/drivers/net directory to your favourite
- temporary directory.
- 2) if you wish, edit the source code near line 1530 to reflect the I/O
- address and IRQ you're using (see also 5).
- 3) compile depca.c, but include -DMODULE in the command line to ensure
- that the correct bits are compiled (see end of source code).
- 4) if you are wanting to add a new card, goto 5. Otherwise, recompile a
- kernel with the depca configuration turned off and reboot.
- 5) insmod depca.o [irq=7] [io=0x200] [mem=0xd0000] [adapter_name=DE100]
- [Alan Cox: Changed the code to allow command line irq/io assignments]
- [Dave Davies: Changed the code to allow command line mem/name
- assignments]
- 6) run the net startup bits for your eth?? interface manually
- (usually /etc/rc.inet[12] at boot time).
- 7) enjoy!
-
- Note that autoprobing is not allowed in loadable modules - the system is
- already up and running and you're messing with interrupts.
-
- To unload a module, turn off the associated interface
- 'ifconfig eth?? down' then 'rmmod depca'.
-
- To assign a base memory address for the shared memory when running as a
- loadable module, see 5 above. To include the adapter name (if you have
- no PROM but know the card name) also see 5 above. Note that this last
- option will not work with kernel built-in depca's.
-
- The shared memory assignment for a loadable module makes sense to avoid
- the 'memory autoprobe' picking the wrong shared memory (for the case of
- 2 depca's in a PC).
-
- ************************************************************************
- 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).

-/* ewrk3.c: A DIGITAL EtherWORKS 3 ethernet driver for Linux.
-
- Written 1994 by David C. Davies.
-
- Copyright 1994 Digital Equipment Corporation.
-
- This software may be used and distributed according to the terms of
- the GNU General Public License, incorporated herein by reference.
-
- This driver is written for the Digital Equipment Corporation series
- of EtherWORKS ethernet cards:
-
- DE203 Turbo (BNC)
- DE204 Turbo (TP)
- DE205 Turbo (TP BNC)
-
- The driver has been tested on a relatively busy network using the DE205
- card and benchmarked with 'ttcp': it transferred 16M of data at 975kB/s
- (7.8Mb/s) to a DECstation 5000/200.
-
- The author may be reached at davies@maniac.ultranet.com.
-
- =========================================================================
- This driver has been written substantially from scratch, although its
- inheritance of style and stack interface from 'depca.c' and in turn from
- Donald Becker's 'lance.c' should be obvious.
-
- The DE203/4/5 boards all use a new proprietary chip in place of the
- LANCE chip used in prior cards (DEPCA, DE100, DE200/1/2, DE210, DE422).
- Use the depca.c driver in the standard distribution for the LANCE based
- cards from DIGITAL; this driver will not work with them.
-
- The DE203/4/5 cards have 2 main modes: shared memory and I/O only. I/O
- only makes all the card accesses through I/O transactions and no high
- (shared) memory is used. This mode provides a >48% performance penalty
- and is deprecated in this driver, although allowed to provide initial
- setup when hardstrapped.
-
- The shared memory mode comes in 3 flavours: 2kB, 32kB and 64kB. There is
- no point in using any mode other than the 2kB mode - their performances
- are virtually identical, although the driver has been tested in the 2kB
- and 32kB modes. I would suggest you uncomment the line:
-
- FORCE_2K_MODE;
-
- to allow the driver to configure the card as a 2kB card at your current
- base address, thus leaving more room to clutter your system box with
- other memory hungry boards.
-
- As many ISA and EISA cards can be supported under this driver as you
- wish, limited primarily by the available IRQ lines, rather than by the
- available I/O addresses (24 ISA, 16 EISA). I have checked different
- configurations of multiple depca cards and ewrk3 cards and have not
- found a problem yet (provided you have at least depca.c v0.38) ...
-
- The board IRQ setting must be at an unused IRQ which is auto-probed
- using Donald Becker's autoprobe routines. All these cards are at
- {5,10,11,15}.
-
- No 16MB memory limitation should exist with this driver as DMA is not
- used and the common memory area is in low memory on the network card (my
- current system has 20MB and I've not had problems yet).
-
- The ability to load this driver as a loadable module has been included
- and used extensively during the driver development (to save those long
- reboot sequences). To utilise this ability, you have to do 8 things:
-
- 0) have a copy of the loadable modules code installed on your system.
- 1) copy ewrk3.c from the /linux/drivers/net directory to your favourite
- temporary directory.
- 2) edit the source code near line 1898 to reflect the I/O address and
- IRQ you're using.
- 3) compile ewrk3.c, but include -DMODULE in the command line to ensure
- that the correct bits are compiled (see end of source code).
- 4) if you are wanting to add a new card, goto 5. Otherwise, recompile a
- kernel with the ewrk3 configuration turned off and reboot.
- 5) insmod ewrk3.o
- [Alan Cox: Changed this so you can insmod ewrk3.o irq=x io=y]
- [Adam Kropelin: now accepts irq=x1,x2 io=y1,y2 for multiple cards]
- 6) run the net startup bits for your new eth?? interface manually
- (usually /etc/rc.inet[12] at boot time).
- 7) enjoy!
-
- Note that autoprobing is not allowed in loadable modules - the system is
- already up and running and you're messing with interrupts.
-
- To unload a module, turn off the associated interface
- 'ifconfig eth?? down' then 'rmmod ewrk3'.
-
- Promiscuous mode has been turned off in this driver, but all the
- multicast address bits have been turned on. This improved the send
- performance on a busy network by about 13%.
-
- Ioctl's have now been provided (primarily because I wanted to grab some
- packet size statistics). They are patterned after 'plipconfig.c' from a
- suggestion by Alan Cox. Using these ioctls, you can enable promiscuous
- mode, add/delete multicast addresses, change the hardware address, get
- packet size distribution statistics and muck around with the control and
- status register. I'll add others if and when the need arises.

-
- This is a device driver for the Allied Telesis AT1700, and
- Fujitsu FMV-181/182/181A/182A/183/184/183A/184A, which are
- straight-forward Fujitsu MB86965 implementations.
-
- Modification for Fujitsu FMV-18X cards is done by Yutaka Tamiya
- (tamy@flab.fujitsu.co.jp).
-
- Sources:
- The Fujitsu MB86965 datasheet.
-
- After the initial version of this driver was written Gerry Sawkins of
- ATI provided their EEPROM configuration code header file.
- Thanks to NIIBE Yutaka <gniibe@mri.co.jp> for bug fixes.
-
- MCA bus (AT1720) support (now deleted) by Rene Schmit <rene@bss.lu>
-
- Bugs:
- The MB86965 has a design flaw that makes all probes unreliable. Not
- only is it difficult to detect, it also moves around in I/O space in
- response to inb()s from other device probes!

-/* eth16i.c An ICL EtherTeam 16i and 32 EISA ethernet driver for Linux
-
- Written 1994-1999 by Mika Kuoppala

- Copyright (C) 1994-1999 by Mika Kuoppala
- Based on skeleton.c and heavily on at1700.c by Donald Becker
-
- 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 miku@iki.fi
-
- This driver supports following cards :
- - ICL EtherTeam 16i
- - ICL EtherTeam 32 EISA
- (Uses true 32 bit transfers rather than 16i compatibility mode)
-
- Example Module usage:
- insmod eth16i.o io=0x2a0 mediatype=bnc
-
- mediatype can be one of the following: bnc,tp,dix,auto,eprom
-
- 'auto' will try to autoprobe mediatype.
- 'eprom' will use whatever type defined in eprom.
-
- I have benchmarked driver with PII/300Mhz as a ftp client
- and 486/33Mhz as a ftp server. Top speed was 1128.37 kilobytes/sec.

- Revision history:
-
- Version Date Description
-
- 0.01 15.12-94 Initial version (card detection)
- 0.02 23.01-95 Interrupt is now hooked correctly
- 0.03 01.02-95 Rewrote initialization part
- 0.04 07.02-95 Base skeleton done...
- Made a few changes to signature checking
- to make it a bit reliable.
- - fixed bug in tx_buf mapping
- - fixed bug in initialization (DLC_EN
- wasn't enabled when initialization
- was done.)
- 0.05 08.02-95 If there were more than one packet to send,
- transmit was jammed due to invalid
- register write...now fixed
- 0.06 19.02-95 Rewrote interrupt handling
- 0.07 13.04-95 Wrote EEPROM read routines
- Card configuration now set according to
- data read from EEPROM
- 0.08 23.06-95 Wrote part that tries to probe used interface
- port if AUTO is selected
-
- 0.09 01.09-95 Added module support
-
- 0.10 04.09-95 Fixed receive packet allocation to work
- with kernels > 1.3.x
-
- 0.20 20.09-95 Added support for EtherTeam32 EISA
-
- 0.21 17.10-95 Removed the unnecessary extern
- init_etherdev() declaration. Some
- other cleanups.
-
- 0.22 22.02-96 Receive buffer was not flushed
- correctly when faulty packet was
- received. Now fixed.
-
- 0.23 26.02-96 Made resetting the adapter
- more reliable.
-
- 0.24 27.02-96 Rewrote faulty packet handling in eth16i_rx
-
- 0.25 22.05-96 kfree() was missing from cleanup_module.
-
- 0.26 11.06-96 Sometimes card was not found by
- check_signature(). Now made more reliable.
-
- 0.27 23.06-96 Oops. 16 consecutive collisions halted
- adapter. Now will try to retransmit
- MAX_COL_16 times before finally giving up.
-
- 0.28 28.10-97 Added dev_id parameter (NULL) for free_irq
-
- 0.29 29.10-97 Multiple card support for module users
-
- 0.30 30.10-97 Fixed irq allocation bug.
- (request_irq moved from probe to open)
-
- 0.30a 21.08-98 Card detection made more relaxed. Driver
- had problems with some TCP/IP-PROM boots
- to find the card. Suggested by
- Kurt Huwig <kurt@huwig.de>
-
- 0.31 28.08-98 Media interface port can now be selected
- with module parameters or kernel
- boot parameters.
-
- 0.32 31.08-98 IRQ was never freed if open/close
- pair wasn't called. Now fixed.
-
- 0.33 10.09-98 When eth16i_open() was called after
- eth16i_close() chip never recovered.
- Now more shallow reset is made on
- close.
-
- 0.34 29.06-99 Fixed one bad #ifdef.
- Changed ioaddr -> io for consistency
-
- 0.35 01.07-99 transmit,-receive bytes were never
- updated in stats.
-
- Bugs:
- In some cases the media interface autoprobing code doesn't find
- the correct interface type. In this case you can
- manually choose the interface type in DOS with E16IC.EXE which is
- configuration software for EtherTeam16i and EtherTeam32 cards.
- This is also true for IRQ setting. You cannot use module
- parameter to configure IRQ of the card (yet).
-
- To do:
- - Real multicast support
- - Rewrite the media interface autoprobing code. Its _horrible_ !
- - Possibly merge all the MB86965 specific code to external
- module for use by eth16.c and Donald's at1700.c
- - IRQ configuration with module parameter. I will do
- this when i will get enough info about setting
- irq without configuration utility.

- * Linux Ethernet device driver for the 3Com Etherlink Plus (3C505)
- * By Craig Southeren, Juha Laiho and Philip Blundell
- *
- * 3c505.c This module implements an interface to the 3Com
- * Etherlink Plus (3c505) Ethernet card. Linux device
- * driver interface reverse engineered from the Linux 3C509
- * device drivers. Some 3C505 information gleaned from
- * the Crynwr packet driver. Still this driver would not
- * be here without 3C505 technical reference provided by
- * 3Com.

-/* Theory of operation:
- *
- * The 3c505 is quite an intelligent board. All communication with it is done
- * by means of Primary Command Blocks (PCBs); these are transferred using PIO
- * through the command register. The card has 256k of on-board RAM, which is
- * used to buffer received packets. It might seem at first that more buffers
- * are better, but in fact this isn't true. From my tests, it seems that
- * more than about 10 buffers are unnecessary, and there is a noticeable
- * performance hit in having more active on the card. So the majority of the
- * card's memory isn't, in fact, used. Sadly, the card only has one transmit
- * buffer and, short of loading our own firmware into it (which is what some
- * drivers resort to) there's nothing we can do about this.
- *
- * We keep up to 4 "receive packet" commands active on the board at a time.
- * When a packet comes in, so long as there is a receive command active, the
- * board will send us a "packet received" PCB and then add the data for that
- * packet to the DMA queue. If a DMA transfer is not already in progress, we
- * set one up to start uploading the data. We have to maintain a list of
- * backlogged receive packets, because the card may decide to tell us about
- * a newly-arrived packet at any time, and we may not be able to start a DMA
- * transfer immediately (ie one may already be going on). We can't NAK the
- * PCB, because then it would throw the packet away.
- *
- * Trying to send a PCB to the card at the wrong moment seems to have bad
- * effects. If we send it a transmit PCB while a receive DMA is happening,
- * it will just NAK the PCB and so we will have wasted our time. Worse, it
- * sometimes seems to interrupt the transfer. The majority of the low-level
- * code is protected by one huge semaphore -- "busy" -- which is set whenever
- * it probably isn't safe to do anything to the card. The receive routine
- * must gain a lock on "busy" before it can start a DMA transfer, and the
- * transmit routine must gain a lock before it sends the first PCB to the card.
- * The send_pcb() routine also has an internal semaphore to protect it against
- * being re-entered (which would be disastrous) -- this is needed because
- * several things can happen asynchronously (re-priming the receiver and
- * asking the card for statistics, for example). send_pcb() will also refuse
- * to talk to the card at all if a DMA upload is happening. The higher-level
- * networking code will reschedule a later retry if some part of the driver
- * is blocked. In practice, this doesn't seem to happen very often.
- */
-
-/* This driver may now work with revision 2.x hardware, since all the read
- * operations on the HCR have been removed (we now keep our own softcopy).
- * But I don't have an old card to test it on.
- *
- * This has had the bad effect that the autoprobe routine is now a bit
- * less friendly to other devices. However, it was never very good.
- * before, so I doubt it will hurt anybody.
- */
-
-/* The driver is a mess. I took Craig's and Juha's code, and hacked it firstly
- * to make it more reliable, and secondly to add DMA mode. Many things could
- * probably be done better; the concurrency protection is particularly awful.

- That's it: only 86 bytes to set up the beast, including every extra
- command available. The 170 byte buffer at DUMP_DATA is shared between the
- Dump command (called only by the diagnostic program) and the SetMulticastList
- command.
-
- To complete the memory setup you only have to write the station address at
- SA_OFFSET and create the Tx & Rx buffer lists.
-
- The Tx command chain and buffer list is setup as follows:
- A Tx command table, with the data buffer pointing to...
- A Tx data buffer descriptor. The packet is in a single buffer, rather than
- chaining together several smaller buffers.
- A NoOp command, which initially points to itself,
- And the packet data.
-
- A transmit is done by filling in the Tx command table and data buffer,
- re-writing the NoOp command, and finally changing the offset of the last
- command to point to the current Tx command. When the Tx command is finished,
- it jumps to the NoOp, when it loops until the next Tx command changes the
- "link offset" in the NoOp. This way the 82586 never has to go through the
- slow restart sequence.
-
- The Rx buffer list is set up in the obvious ring structure. We have enough
- memory (and low enough interrupt latency) that we can avoid the complicated
- Rx buffer linked lists by alway associating a full-size Rx data buffer with
- each Rx data frame.
-
- I current use four transmit buffers starting at TX_BUF_START (0x0100), and
- use the rest of memory, from RX_BUF_START to RX_BUF_END, for Rx buffers.

-
- Things remaining to do:
- Better record keeping of errors.
- Eliminate transmit interrupt to reduce overhead.
- Implement "concurrent processing". I won't be doing it!
-
- Bugs:
-
- If you have a problem of not detecting the 82595 during a
- reboot (warm reset), disable the FLASH memory should fix it.
- This is a compatibility hardware problem.
-
- Versions:
- 0.13b basic ethtool support (aris, 09/13/2004)
- 0.13a in memory shortage, drop packets also in board
- (Michael Westermann <mw@microdata-pos.de>, 07/30/2002)
- 0.13 irq sharing, rewrote probe function, fixed a nasty bug in
- hardware_send_packet and a major cleanup (aris, 11/08/2001)
- 0.12d fixing a problem with single card detected as eight eth devices
- fixing a problem with sudden drop in card performance
- (chris (asdn@go2.pl), 10/29/2001)
- 0.12c fixing some problems with old cards (aris, 01/08/2001)
- 0.12b misc fixes (aris, 06/26/2000)
- 0.12a port of version 0.12a of 2.2.x kernels to 2.3.x
- (aris (aris@conectiva.com.br), 05/19/2000)
- 0.11e some tweaks about multiple cards support (PdP, jul/aug 1999)
- 0.11d added __initdata, __init stuff; call spin_lock_init
- in eepro_probe1. Replaced "eepro" by dev->name. Augmented
- the code protected by spin_lock in interrupt routine
- (PdP, 12/12/1998)
- 0.11c minor cleanup (PdP, RMC, 09/12/1998)
- 0.11b Pascal Dupuis (dupuis@lei.ucl.ac.be): works as a module
- under 2.1.xx. Debug messages are flagged as KERN_DEBUG to
- avoid console flooding. Added locking at critical parts. Now
- the dawn thing is SMP safe.
- 0.11a Attempt to get 2.1.xx support up (RMC)
- 0.11 Brian Candler added support for multiple cards. Tested as
- a module, no idea if it works when compiled into kernel.
-
- 0.10e Rick Bressler notified me that ifconfig up;ifconfig down fails
- because the irq is lost somewhere. Fixed that by moving
- request_irq and free_irq to eepro_open and eepro_close respectively.
- 0.10d Ugh! Now Wakeup works. Was seriously broken in my first attempt.
- I'll need to find a way to specify an ioport other than
- the default one in the PnP case. PnP definitively sucks.
- And, yes, this is not the only reason.
- 0.10c PnP Wakeup Test for 595FX. uncomment #define PnPWakeup;
- to use.
- 0.10b Should work now with (some) Pro/10+. At least for
- me (and my two cards) it does. _No_ guarantee for
- function with non-Pro/10+ cards! (don't have any)
- (RMC, 9/11/96)
-
- 0.10 Added support for the Etherexpress Pro/10+. The
- IRQ map was changed significantly from the old
- pro/10. The new interrupt map was provided by
- Rainer M. Canavan (Canavan@Zeus.cs.bonn.edu).
- (BCH, 9/3/96)
-
- 0.09 Fixed a race condition in the transmit algorithm,
- which causes crashes under heavy load with fast
- pentium computers. The performance should also
- improve a bit. The size of RX buffer, and hence
- TX buffer, can also be changed via lilo or insmod.
- (BCH, 7/31/96)
-
- 0.08 Implement 32-bit I/O for the 82595TX and 82595FX
- based lan cards. Disable full-duplex mode if TPE
- is not used. (BCH, 4/8/96)
-
- 0.07a Fix a stat report which counts every packet as a
- heart-beat failure. (BCH, 6/3/95)
-
- 0.07 Modified to support all other 82595-based lan cards.
- The IRQ vector of the EtherExpress Pro will be set
- according to the value saved in the EEPROM. For other
- cards, I will do autoirq_request() to grab the next
- available interrupt vector. (BCH, 3/17/95)
-
- 0.06a,b Interim released. Minor changes in the comments and
- print out format. (BCH, 3/9/95 and 3/14/95)
-
- 0.06 First stable release that I am comfortable with. (BCH,
- 3/2/95)
-
- 0.05 Complete testing of multicast. (BCH, 2/23/95)
-
- 0.04 Adding multicast support. (BCH, 2/14/95)
-
- 0.03 First widely alpha release for public testing.
- (BCH, 2/14/95)

-
- This driver is written by cutting and pasting the skeleton.c driver

- Details of the i82595.
-
-You will need either the datasheet or the user manual to understand what
-is going on here. The 82595 is very different from the 82586, 82593.
-
-The receive algorithm in eepro_rx() is just an implementation of the
-RCV ring structure that the Intel 82595 imposes at the hardware level.
-The receive buffer is set at 24K, and the transmit buffer is 8K. I
-am assuming that the total buffer memory is 32K, which is true for the
-Intel EtherExpress Pro/10. If it is less than that on a generic card,
-the driver will be broken.
-
-The transmit algorithm in the hardware_send_packet() is similar to the
-one in the eepro_rx(). The transmit buffer is a ring linked list.
-I just queue the next available packet to the end of the list. In my
-system, the 82595 is so fast that the list seems to always contain a
-single packet. In other systems with faster computers and more congested
-network traffics, the ring linked list should improve performance by
-allowing up to 8K worth of packets to be queued.
-
-The sizes of the receive and transmit buffers can now be changed via lilo
-or insmod. Lilo uses the appended line "ether=io,irq,debug,rx-buffer,eth0"
-where rx-buffer is in KB unit. Modules uses the parameter mem which is
-also in KB unit, for example "insmod io=io-address irq=0 mem=rx-buffer."
-The receive buffer has to be more than 3K or less than 29K. Otherwise,
-it is reset to the default of 24K, and, hence, 8K for the trasnmit
-buffer (transmit-buffer = 32K - receive-buffer).

-/* Intel EtherExpress 16 device driver for Linux
- *
- * Written by John Sullivan, 1995
- * based on original code by Donald Becker, with changes by
- * Alan Cox and Pauline Middelink.
- *
- * Support for 8-bit mode by Zoltan Szilagyi <zoltans@cs.arizona.edu>
- *
- * Many modifications, and currently maintained, by
- * Philip Blundell <philb@gnu.org>
- * Added the Compaq LTE Alan Cox <alan@lxorguk.ukuu.org.uk>
- * Added MCA support Adam Fritzler (now deleted)
- *
- * Note - this driver is experimental still - it has problems on faster
- * machines. Someone needs to sit down and go through it line by line with
- * a databook...
- */
-
-/* The EtherExpress 16 is a fairly simple card, based on a shared-memory
- * design using the i82586 Ethernet coprocessor. It bears no relationship,
- * as far as I know, to the similarly-named "EtherExpress Pro" range.
- *
- * Historically, Linux support for these cards has been very bad. However,
- * things seem to be getting better slowly.
- */
-
-/* If your card is confused about what sort of interface it has (eg it
- * persistently reports "10baseT" when none is fitted), running 'SOFTSET /BART'
- * or 'SOFTSET /LISA' from DOS seems to help.
- */
-
-/* Here's the scoop on memory mapping.
- *
- * There are three ways to access EtherExpress card memory: either using the
- * shared-memory mapping, or using PIO through the dataport, or using PIO
- * through the "shadow memory" ports.
- *
- * The shadow memory system works by having the card map some of its memory
- * as follows:
- *
- * (the low five bits of the SMPTR are ignored)
- *
- * base+0x4000..400f memory at SMPTR+0..15
- * base+0x8000..800f memory at SMPTR+16..31
- * base+0xc000..c007 dubious stuff (memory at SMPTR+16..23 apparently)
- * base+0xc008..c00f memory at 0x0008..0x000f
- *
- * This last set (the one at c008) is particularly handy because the SCB
- * lives at 0x0008. So that set of ports gives us easy random access to data
- * in the SCB without having to mess around setting up pointers and the like.
- * We always use this method to access the SCB (via the scb_xx() functions).
- *
- * Dataport access works by aiming the appropriate (read or write) pointer
- * at the first address you're interested in, and then reading or writing from
- * the dataport. The pointers auto-increment after each transfer. We use
- * this for data transfer.
- *
- * We don't use the shared-memory system because it allegedly doesn't work on
- * all cards, and because it's a bit more prone to go wrong (it's one more
- * thing to configure...).
- */
-
-/* Known bugs:
- *
- * - The card seems to want to give us two interrupts every time something
- * happens, where just one would be better.
- */
-
-/*
- *
- * Note by Zoltan Szilagyi 10-12-96:
- *
- * I've succeeded in eliminating the "CU wedged" messages, and hence the
- * lockups, which were only occurring with cards running in 8-bit mode ("force
- * 8-bit operation" in Intel's SoftSet utility). This version of the driver
- * sets the 82586 and the ASIC to 8-bit mode at startup; it also stops the
- * CU before submitting a packet for transmission, and then restarts it as soon
- * as the process of handing the packet is complete. This is definitely an
- * unnecessary slowdown if the card is running in 16-bit mode; therefore one
- * should detect 16-bit vs 8-bit mode from the EEPROM settings and act
- * accordingly. In 8-bit mode with this bugfix I'm getting about 150 K/s for
- * ftp's, which is significantly better than I get in DOS, so the overhead of
- * stopping and restarting the CU with each transmit is not prohibitive in
- * practice.
- *
- * Update by David Woodhouse 11/5/99:
- *
- * I've seen "CU wedged" messages in 16-bit mode, on the Alpha architecture.
- * I assume that this is because 16-bit accesses are actually handled as two
- * 8-bit accesses.

-through linked lists of commands and buffers in the hostprocessors memory.
-A complete description of the 82596 is available from intel. Search for
-a file called "29021806.pdf". It is a complete description of the chip itself.
-To use it for the pws some additions are needed regarding generation of
-the PORT and CA signal, and the interrupt glue needed for a pc.
-I/O map:
-PORT SIZE ACTION MEANING
-0xCB0 2 WRITE Lower 16 bits for PORT command
-0xCB2 2 WRITE Upper 16 bits for PORT command, and issue of PORT command
-0xCB4 1 WRITE Generation of CA signal
-0xCB8 1 WRITE Clear interrupt glue
-All other communication is through memory!

- * CAN YOU PLEASE REPORT ME YOUR PERFORMANCE EXPERIENCES !!.
- *
- * If you find a bug, please report me:
- * The kernel panic output and any kmsg from the ni52 driver
- * the ni5210-driver-version and the linux-kernel version
- * how many shared memory (memsize) on the netcard,
- * bootprom: yes/no, base_addr, mem_start
- * maybe the ni5210-card revision and the i82586 version
- *
- * autoprobe for: base_addr: 0x300,0x280,0x360,0x320,0x340

- * 0xd8000,0xcc000,0xce000,0xda000,0xdc000
- *
- * sources:
- * skeleton.c from Donald Becker
- *
- * I have also done a look in the following sources: (mail me if you need them)
- * crynwr-packet-driver by Russ Nelson
- * Garret A. Wollman's (fourth) i82586-driver for BSD
- * (before getting an i82596 (yes 596 not 586) manual, the existing drivers
- * helped me a lot to understand this tricky chip.)
- *
- * Known Problems:
- * The internal sysbus seems to be slow. So we often lose packets because of
- * overruns while receiving from a fast remote host.
- * This can slow down TCP connections. Maybe the newer ni5210 cards are
- * better. My experience is, that if a machine sends with more than about
- * 500-600K/s the fifo/sysbus overflows.
- *
- * IMPORTANT NOTE:
- * On fast networks, it's a (very) good idea to have 16K shared memory. With
- * 8K, we can store only 4 receive frames, so it can (easily) happen that a
- * remote machine 'overruns' our system.
- *
- * Known i82586/card problems (I'm sure, there are many more!):
- * Running the NOP-mode, the i82586 sometimes seems to forget to report
- * every xmit-interrupt until we restart the CU.
- * Another MAJOR bug is, that the RU sometimes seems to ignore the EL-Bit
- * in the RBD-Struct which indicates an end of the RBD queue.
- * Instead, the RU fetches another (randomly selected and
- * usually used) RBD and begins to fill it. (Maybe, this happens only if
- * the last buffer from the previous RFD fits exact into the queue and
- * the next RFD can't fetch an initial RBD. Anyone knows more? )
- *
- * results from ftp performance tests with Linux 1.2.5
- * send and receive about 350-400 KByte/s (peak up to 460 kbytes/s)
- * sending in NOP-mode: peak performance up to 530K/s (but better don't
- * run this mode)

-/* znet.c: An Zenith Z-Note ethernet driver for linux. */
-
-/*
- Written by Donald Becker.
-
- The author may be reached as becker@scyld.com.
- This driver is based on the Linux skeleton driver. The copyright of the
- skeleton driver is held by the United States Government, as represented
- by DIRNSA, and it is released under the GPL.
-
- Thanks to Mike Hollick for alpha testing and suggestions.
-
- References:
- The Crynwr packet driver.
-
- "82593 CSMA/CD Core LAN Controller" Intel datasheet, 1992
- Intel Microcommunications Databook, Vol. 1, 1990.
- As usual with Intel, the documentation is incomplete and inaccurate.
- I had to read the Crynwr packet driver to figure out how to actually
- use the i82593, and guess at what register bits matched the loosely
- related i82586.
-
- Theory of Operation
-
- The i82593 used in the Zenith Z-Note series operates using two(!) slave
- DMA channels, one interrupt, and one 8-bit I/O port.
-
- While there several ways to configure '593 DMA system, I chose the one
- that seemed commensurate with the highest system performance in the face
- of moderate interrupt latency: Both DMA channels are configured as
- recirculating ring buffers, with one channel (#0) dedicated to Rx and
- the other channel (#1) to Tx and configuration. (Note that this is
- different than the Crynwr driver, where the Tx DMA channel is initialized
- before each operation. That approach simplifies operation and Tx error
- recovery, but requires additional I/O in normal operation and precludes
- transmit buffer chaining.)
-
- Both rings are set to 8192 bytes using {TX,RX}_RING_SIZE. This provides
- a reasonable ring size for Rx, while simplifying DMA buffer allocation --
- DMA buffers must not cross a 128K boundary. (In truth the size selection
- was influenced by my lack of '593 documentation. I thus was constrained
- to use the Crynwr '593 initialization table, which sets the Rx ring size
- to 8K.)
-
- Despite my usual low opinion about Intel-designed parts, I must admit
- that the bulk data handling of the i82593 is a good design for
- an integrated system, like a laptop, where using two slave DMA channels
- doesn't pose a problem. I still take issue with using only a single I/O
- port. In the same controlled environment there are essentially no
- limitations on I/O space, and using multiple locations would eliminate
- the need for multiple operations when looking at status registers,
- setting the Rx ring boundary, or switching to promiscuous mode.
-
- I also question Zenith's selection of the '593: one of the advertised
- advantages of earlier Intel parts was that if you figured out the magic
- initialization incantation you could use the same part on many different
- network types. Zenith's use of the "FriendlyNet" (sic) connector rather
- than an on-board transceiver leads me to believe that they were planning
- to take advantage of this. But, uhmmm, the '593 omits all but ethernet
- functionality from the serial subsystem.

-/* 10/2002
-
- o Resurected for Linux 2.5+ by Marc Zyngier <maz@wild-wind.fr.eu.org> :
-
- - Removed strange DMA snooping in znet_sent_packet, which lead to
- TX buffer corruption on my laptop.
- - Use init_etherdev stuff.
- - Use kmalloc-ed DMA buffers.
- - Use as few global variables as possible.
- - Use proper resources management.
- - Use wireless/i82593.h as much as possible (structure, constants)
- - Compiles as module or build-in.
- - Now survives unplugging/replugging cable.
-
- Some code was taken from wavelan_cs.
-
- Tested on a vintage Zenith Z-Note 433Lnp+. Probably broken on
- anything else. Testers (and detailed bug reports) are welcome :-).
-
- o TODO :
-
- - Properly handle multicast
- - Understand why some traffic patterns add a 1s latency...

-special acknowledgements to:
- - Bob Eager for helping me out with documentation from IBM
- - Jim Shorney for his endless patience with me while I was using
- him as a beta tester to trace down the address filter bug ;-)
-
- Missing things:
-
- -> set debug level via ioctl instead of compile-time switches
- -> I didn't follow the development of the 2.1.x kernels, so my
- assumptions about which things changed with which kernel version
- are probably nonsense
-
-History:
- Nov 6th, 1999
- startup from SK_MCA driver
- Dec 6th, 1999
- finally got docs about the card. A big thank you to Bob Eager!
- Dec 12th, 1999
- first packet received
- Dec 13th, 1999
- recv queue done, tcpdump works
- Dec 15th, 1999
- transmission part works
- Dec 28th, 1999
- added usage of the isa_functions for Linux 2.3 . Things should
- still work with 2.0.x....
- Jan 28th, 2000
- in Linux 2.2.13, the version.h file mysteriously didn't get
- included. Added a workaround for this. Furthermore, it now
- not only compiles as a modules ;-)
- Jan 30th, 2000
- newer kernels automatically probe more than one board, so the
- 'startslot' as a variable is also needed here
- Apr 12th, 2000
- the interrupt mask register is not set 'hard' instead of individually
- setting registers, since this seems to set bits that shouldn't be
- set
- May 21st, 2000
- reset interrupt status immediately after CAM load
- add a recovery delay after releasing the chip's reset line
- May 24th, 2000
- finally found the bug in the address filter setup - damned signed
- chars!
- June 1st, 2000
- corrected version codes, added support for the latest 2.3 changes
- Oct 28th, 2002
- cleaned up for the 2.5 tree <alan@lxorguk.ukuu.org.uk>

- * janpascal@vanbest.org andi@lisas.de
- *
- * Sources:
- * Donald Becker's "skeleton.c"
- * Crynwr ni5010 packet driver
- *
- * Changes:
- * v0.0: First test version
- * v0.1: First working version
- * v0.2:
- * v0.3->v0.90: Now demand setting io and irq when loading as module
- * 970430 v0.91: modified for Linux 2.1.14
- * v0.92: Implemented Andreas' (better) NI5010 probe
- * 970503 v0.93: Fixed auto-irq failure on warm reboot (JB)
- * 970623 v1.00: First kernel version (AM)
- * 970814 v1.01: Added detection of onboard receive buffer size (AM)
- * 060611 v1.02: slight cleanup: email addresses, driver modernization.
- * Bugs:
- * - not SMP-safe (no locking of I/O accesses)
- * - Note that you have to patch ifconfig for the new /proc/net/dev
- * format. It gives incorrect stats otherwise.
- *
- * To do:
- * Fix all bugs :-)
- * Move some stuff to chipset_init()
- * Handle xmt errors other than collisions
- * Complete merge with Andreas' driver
- * Implement ring buffers (Is this useful? You can't squeeze
- * too many packet in a 2k buffer!)
- * Implement DMA (Again, is this useful? Some docs say DMA is
- * slower than programmed I/O)
- *
- * Compile with:
- * gcc -O2 -fomit-frame-pointer -m486 -D__KERNEL__ \
- * -DMODULE -c ni5010.c
- *
- * Insert with e.g.:
- * insmod ni5010.ko io=0x300 irq=5

-* ============================================================================
-* 2001/01/12 acme use dev_kfree_skb_irq on interrupt context
-* 2000/04/02 acme dprintk, cycx_debug
-* fixed the bug introduced in get_dev_by_lcn and
-* get_dev_by_dte_addr by the anonymous hacker
-* that converted this driver to softnet
-* 2000/01/08 acme cleanup
-* 1999/10/27 acme use ARPHRD_HWX25 so that the X.25 stack know
-* that we have a X.25 stack implemented in
-* firmware onboard
-* 1999/10/18 acme support for X.25 sockets in if_send,
-* beware: socket(AF_X25...) IS WORK IN PROGRESS,
-* TCP/IP over X.25 via wanrouter not affected,
-* working.
-* 1999/10/09 acme chan_disc renamed to chan_disconnect,
-* began adding support for X.25 sockets:
-* conf->protocol in new_if
-* 1999/10/05 acme fixed return E... to return -E...
-* 1999/08/10 acme serialized access to the card thru a spinlock
-* in x25_exec
-* 1999/08/09 acme removed per channel spinlocks
-* removed references to enable_tx_int
-* 1999/05/28 acme fixed nibble_to_byte, ackvc now properly treated
-* if_send simplified
-* 1999/05/25 acme fixed t1, t2, t21 & t23 configuration
-* use spinlocks instead of cli/sti in some points
-* 1999/05/24 acme finished the x25_get_stat function
-* 1999/05/23 acme dev->type = ARPHRD_X25 (tcpdump only works,
-* AFAIT, with ARPHRD_ETHER). This seems to be
-* needed to use socket(AF_X25)...
-* Now the config file must specify a peer media
-* address for svc channels over a crossover cable.
-* Removed hold_timeout from x25_channel_t,
-* not used.
-* A little enhancement in the DEBUG processing
-* 1999/05/22 acme go to DISCONNECTED in disconnect_confirm_intr,
-* instead of chan_disc.
-* 1999/05/16 marcelo fixed timer initialization in SVCs
-* 1999/01/05 acme x25_configure now get (most of) all
-* parameters...
-* 1999/01/05 acme pktlen now (correctly) uses log2 (value
-* configured)
-* 1999/01/03 acme judicious use of data types (u8, u16, u32, etc)
-* 1999/01/03 acme cyx_isr: reset dpmbase to acknowledge
-* indication (interrupt from cyclom 2x)
-* 1999/01/02 acme cyx_isr: first hackings...
-* 1999/01/0203 acme when initializing an array don't give less
-* elements than declared...
-* example: char send_cmd[6] = "?\xFF\x10";
-* you'll gonna lose a couple hours, 'cause your
-* brain won't admit that there's an error in the
-* above declaration... the side effect is that
-* memset is put into the unresolved symbols
-* instead of using the inline memset functions...
-* 1999/01/02 acme began chan_connect, chan_send, x25_send
-* 1998/12/31 acme x25_configure
-* this code can be compiled as non module
-* 1998/12/27 acme code cleanup
-* IPX code wiped out! let's decrease code
-* complexity for now, remember: I'm learning! :)
-* bps_to_speed_code OK
-* 1998/12/26 acme Minimal debug code cleanup
-* 1998/08/08 acme Initial version.

+/**
+ * DOC: station table - introduction
+ *
+ * The station table is a list of data structure that reprensent the stations.
+ * In STA/P2P client mode, the driver will hold one station for the AP/ GO.
+ * In GO/AP mode, the driver will have as many stations as associated clients.
+ * All these stations are reflected in the fw's station table. The driver
+ * keeps the fw's station table up to date with the ADD_STA command. Stations
+ * can be removed by the REMOVE_STA command.
+ *
+ * All the data related to a station is held in the structure %iwl_mvm_sta
+ * which is embed in the mac80211's %ieee80211_sta (in the drv_priv) area.
+ * This data includes the index of the station in the fw, per tid information
+ * (sequence numbers, Block-ack state machine, etc...). The stations are
+ * created and deleted by the %sta_state callback from %ieee80211_ops.
+ *
+ * The driver holds a map: %fw_id_to_mac_id that allows to fetch a
+ * %ieee80211_sta (and the %iwl_mvm_sta embedded into it) based on a fw
+ * station index. That way, the driver is able to get the tid related data in
+ * O(1) in time sensitive paths (Tx / Tx response / BA notification). These
+ * paths are triggered by the fw, and the driver needs to get a pointer to the
+ * %ieee80211 structure. This map helps to get that pointer quickly.
+ */
+
+/**
+ * DOC: station table - locking
+ *
+ * As stated before, the station is created / deleted by mac80211's %sta_state
+ * callback from %ieee80211_ops which can sleep. The next paragraph explains
+ * the locking of a single stations, the next ones relates to the station
+ * table.
+ *
+ * The station holds the sequence number per tid. So this data needs to be
+ * accessed in the Tx path (which is softIRQ). It also holds the Block-Ack
+ * information (the state machine / and the logic that checks if the queues
+ * were drained), so it also needs to be accessible from the Tx response flow.
+ * In short, the station needs to be access from sleepable context as well as
+ * from tasklets, so the station itself needs a spinlock.
+ *
+ * The writers of %fw_id_to_mac_id map are serialized by the global mutex of
+ * the mvm op_mode. This is possible since %sta_state can sleep.
+ * The pointers in this map are RCU protected, hence we won't replace the
+ * station while we have Tx / Tx response / BA notification running.
+ *
+ * If a station is deleted while it still has packets in its A-MPDU queues,
+ * then the reclaim flow will notice that there is no station in the map for
+ * sta_id and it will dump the responses.
+ */
+
+/**
+ * DOC: station table - internal stations
+ *
+ * The FW needs a few internal stations that are not reflected in
+ * mac80211, such as broadcast station in AP / GO mode, or AUX sta for
+ * scanning and P2P device (during the GO negotiation).
+ * For these kind of stations we have %iwl_mvm_int_sta struct which holds the
+ * data relevant for them from both %iwl_mvm_sta and %ieee80211_sta.
+ * Usually the data for these stations is static, so no locking is required,
+ * and no TID data as this is also not needed.
+ * One thing to note, is that these stations have an ID in the fw, but not
+ * in mac80211. In order to "reserve" them a sta_id in %fw_id_to_mac_id
+ * we fill ERR_PTR(EINVAL) in this mapping and all other dereferencing of
+ * pointers from this mapping need to check that the value is not error
+ * or NULL.
+ *
+ * Currently there is only one auxiliary station for scanning, initialized
+ * on init.

+/**
+ * DOC: station table - AP Station in STA mode
+ *
+ * %iwl_mvm_vif includes the index of the AP station in the fw's STA table:
+ * %ap_sta_id. To get the point to the coresponsding %ieee80211_sta,
+ * &fw_id_to_mac_id can be used. Due to the way the fw works, we must not remove
+ * the AP station from the fw before setting the MAC context as unassociated.
+ * Hence, %fw_id_to_mac_id[%ap_sta_id] will be NULLed when the AP station is
+ * removed by mac80211, but the station won't be removed in the fw until the
+ * VIF is set as unassociated. Then, %ap_sta_id will be invalidated.
+ */
+
+/**
+ * DOC: station table - Drain vs. Flush
+ *
+ * Flush means that all the frames in the SCD queue are dumped regardless the
+ * station to which they were sent. We do that when we disassociate and before
+ * we remove the STA of the AP. The flush can be done synchronously against the
+ * fw.
+ * Drain means that the fw will drop all the frames sent to a specific station.
+ * This is useful when a client (if we are IBSS / GO or AP) disassociates. In
+ * that case, we need to drain all the frames for that client from the AC queues
+ * that are shared with the other clients. Only then, we can remove the STA in
+ * the fw. In order to do so, we track the non-AMPDU packets for each station.
+ * If mac80211 removes a STA and if it still has non-AMPDU packets pending in
+ * the queues, we mark this station as %EBUSY in %fw_id_to_mac_id, and drop all
+ * the frames for this STA (%iwl_mvm_rm_sta). When the last frame is dropped
+ * (we know about it with its Tx response), we remove the station in fw and set
+ * it as %NULL in %fw_id_to_mac_id: this is the purpose of
+ * %iwl_mvm_sta_drained_wk.
+ */
+
+/**
+ * DOC: station table - fw restart
+ *
+ * When the fw asserts, or we have any other issue that requires to reset the
+ * driver, we require mac80211 to reconfigure the driver. Since the private
+ * data of the stations is embed in mac80211's %ieee80211_sta, that data will
+ * not be zeroed and needs to be reinitialized manually.
+ * %IWL_MVM_STATUS_IN_HW_RESTART is set during restart and that will hint us
+ * that we must not allocate a new sta_id but reuse the previous one. This
+ * means that the stations being re-added after the reset will have the same
+ * place in the fw as before the reset. We do need to zero the %fw_id_to_mac_id
+ * map, since the stations aren't in the fw any more. Internal stations that
+ * are not added by mac80211 will be re-added in the init flow that is called
+ * after the restart: mac80211 call's %iwl_mvm_mac_start which calls to
+ * %iwl_mvm_up.
+ */
+
+/**
+ * DOC: AP mode - PS
+ *
+ * When a station is asleep, the fw will set it as "asleep". All the
+ * non-aggregation frames to that station will be dropped by the fw
+ * (%TX_STATUS_FAIL_DEST_PS failure code).
+ * AMPDUs are in a separate queue that is stopped by the fw. We just need to
+ * let mac80211 know how many frames we have in these queues so that it can
+ * properly handle trigger frames.
+ * When the a trigger frame is received, mac80211 tells the driver to send
+ * frames from the AMPDU queues or AC queue depending on which queue are
+ * delivery-enabled and what TID has frames to transmit (Note that mac80211 has
+ * all the knowledege since all the non-agg frames are buffered / filtered, and
+ * the driver tells mac80211 about agg frames). The driver needs to tell the fw
+ * to let frames out even if the station is asleep. This is done by
+ * %iwl_mvm_sta_modify_sleep_tx_count.
+ * When we receive a frame from that station with PM bit unset, the
+ * driver needs to let the fw know that this station isn't alseep any more.

+/**
+ * DOC: Time Events - what is it?
+ *
+ * Time Events are a fw feature that allows the driver to control the presence
+ * of the device on the channel. Since the fw supports multiple channels
+ * concurrently, the fw may choose to jump to another channel at any time.
+ * In order to make sure that the fw is on a specific channel at a certain time
+ * and for a certain duration, the driver needs to issue a time event.
+ *
+ * The simplest example is for BSS association. The driver issues a time event,
+ * waits for it to start, and only then tells mac80211 that we can start the
+ * association. This way, we make sure that the association will be done
+ * smoothly and won't be interrupted by channel switch decided within the fw.
+ */
+
+ /**
+ * DOC: The flow against the fw
+ *
+ * When the driver needs to make sure we are in a certain channel, at a certain
+ * time and for a certain duration, it sends a Time Event. The flow against the
+ * fw goes like this:
+ * 1) Driver sends a TIME_EVENT_CMD to the fw
+ * 2) Driver gets the response for that command. This response contains the
+ * Unique ID (UID) of the event.
+ * 3) The fw sends notification when the event starts.
+ *
+ * Of course the API provides various options that allow to cover parameters
+ * of the flow.
+ * What is the duration of the event?
+ * What is the start time of the event?
+ * Is there an end-time for the event?
+ * How much can the event be delayed?

+/* This source file contains the implementation of a special device driver
+ * that intends to provide a *very* fast communication channel between the
+ * guest system and the QEMU emulator.
+ *
+ * Usage from the guest is simply the following (error handling simplified):
+ *
+ * int fd = open("/dev/qemu_pipe",O_RDWR);
+ * .... write() or read() through the pipe.
+ *
+ * This driver doesn't deal with the exact protocol used during the session.
+ * It is intended to be as simple as something like:
+ *
+ * // do this _just_ after opening the fd to connect to a specific
+ * // emulator service.
+ * const char* msg = "<pipename>";
+ * if (write(fd, msg, strlen(msg)+1) < 0) {
+ * ... could not connect to <pipename> service
+ * close(fd);
+ * }
+ *
+ * // after this, simply read() and write() to communicate with the
+ * // service. Exact protocol details left as an exercise to the reader.
+ *
+ * This driver is very fast because it doesn't copy any data through
+ * intermediate buffers, since the emulator is capable of translating
+ * guest user addresses into host ones.
+ *
+ * Note that we must however ensure that each user page involved in the
+ * exchange is properly mapped during a transfer.

- * This is a rewrite of the das08 and das08jr drivers.
+ * This driver is used by the das08_isa, das08_cs, and das08_pci
+ * drivers to provide the common support for the DAS-08 hardware.
*
- * Options (for ISA cards):
- * [0] - base io address
- *
- * Manual configuration of PCI cards is not supported; they are
- * configured automatically.
- *
- * The das08 driver doesn't support asynchronous commands, since
- * the cheap das08 hardware doesn't really support them. The
- * comedi_rt_timer driver can be used to emulate commands for this
- * driver.

1. This driver uses the same unregistered vendor id that the firewire core does
(0xd00d1e). Perhaps this could be exposed as a define in

--- Issues with TTY core --
- 1. Hack for alternate device name scheme
- - because udev no longer allows device renaming, devices should have
- their proper names on creation. This is an issue for creating the
- fwloop<n> device with the fwtty<n> devices because although duplicating
- roughly the same operations as tty_port_register_device() isn't difficult,
- access to the tty_class & tty_fops is restricted in scope.
-
- This is currently being worked around in create_loop_device() by
- extracting the tty_class ptr and tty_fops ptr from the previously created
- tty devices. Perhaps an add'l api can be added -- eg.,
- tty_{port_}register_named_device().

+TODO (general):
+==================================
+
+- User space interface refinement
+ - Controls should be used when possible rather than private ioctl
+ - No enums should be used
+ - Use of MC and V4L2 subdev APIs when applicable
+ - Single interface header might suffice
+ - Current interface forces to configure everything at once
+- Get rid of the dm365_ipipe_hw.[ch] layer
+- Active external sub-devices defined by link configuration; no strcmp
+ needed
+- More generic platform data (i2c adapters)
+- The driver should have no knowledge of possible external subdevs; see
+ struct vpfe_subdev_id
+- Some of the hardware control should be refactorede
+- Check proper serialisation (through mutexes and spinlocks)
+- Names that are visible in kernel global namespace should have a common
+ prefix (or a few)
+- While replacing the older driver in media folder, provide a compatibility
+ layer and compatibility tests that warrants (using the libv4l's LD_PRELOAD
+ approach) there is no regression for the users using the older driver.
+
+Building of uImage and Applications:
+==================================
+
+As of now since the interface will undergo few changes all the include
+files are present in staging itself, to build for dm365 follow below steps,

+Introduction
+============
+
+This file documents the Texas Instruments Davinci Video processing Front End
+(VPFE) driver located under drivers/media/platform/davinci. The original driver
+exists for Davinci VPFE, which is now being changed to Media Controller
+Framework.
+
+Currently the driver has been successfully used on the following
+version of Davinci:
+
+ DM365/DM368
+
+The driver implements V4L2, Media controller and v4l2_subdev interfaces. Sensor,
+lens and flash drivers using the v4l2_subdev interface in the kernel are
+supported.
+
+
+Split to subdevs
+================
+
+The Davinci VPFE is split into V4L2 subdevs, each of the blocks inside the VPFE
+having one subdev to represent it. Each of the subdevs provide a V4L2 subdev
+interface to userspace.
+
+ DAVINCI ISIF
+ DAVINCI IPIPEIF
+ DAVINCI IPIPE
+ DAVINCI CROP RESIZER
+ DAVINCI RESIZER A
+ DAVINCI RESIZER B
+
+Each possible link in the VPFE is modeled by a link in the Media controller
+interface. For an example program see [1].
+
+
+ISIF, IPIPE, and RESIZER block IOCTLs
+======================================
+
+The Davinci Video processing Front End (VPFE) driver supports standard V4L2
+IOCTLs and controls where possible and practical. Much of the functions provided
+by the VPFE, however, does not fall under the standard IOCTL's.
+
+In general, there is a private ioctl for configuring each of the blocks
+containing hardware-dependent functions.
+
+The following private IOCTLs are supported:
+
+ VIDIOC_VPFE_ISIF_[S/G]_RAW_PARAMS
+ VIDIOC_VPFE_IPIPE_[S/G]_CONFIG
+ VIDIOC_VPFE_RSZ_[S/G]_CONFIG
+
+The parameter structures used by these ioctl's are described in
+include/uapi/linux/davinci_vpfe.h.
+
+The VIDIOC_VPFE_ISIF_S_RAW_PARAMS, VIDIOC_VPFE_IPIPE_S_CONFIG and
+VIDIOC_VPFE_RSZ_S_CONFIG are used to configure, enable and disable functions in
+the isif, ipipe and resizer blocks respectively. These IOCTL's control several
+functions in the blocks they control. VIDIOC_VPFE_ISIF_S_RAW_PARAMS IOCTL
+accepts a pointer to struct vpfe_isif_raw_config as its argument. Similarly
+VIDIOC_VPFE_IPIPE_S_CONFIG accepts a pointer to struct vpfe_ipipe_config. And
+VIDIOC_VPFE_RSZ_S_CONFIG accepts a pointer to struct vpfe_rsz_config as its
+argument. Similarly VIDIOC_VPFE_ISIF_G_RAW_PARAMS, VIDIOC_VPFE_IPIPE_G_CONFIG
+and VIDIOC_VPFE_RSZ_G_CONFIG are used to get the current configuration set in
+the isif, ipipe and resizer blocks respectively.
+
+The detailed functions of the VPFE itself related to a given VPFE block is
+described in the Technical Reference Manuals (TRMs) --- see the end of the
+document for those.
+
+
+IPIPEIF block IOCTLs
+======================================
+
+The following private IOCTLs are supported:
+
+ VIDIOC_VPFE_IPIPEIF_[S/G]_CONFIG
+
+The parameter structures used by these ioctl's are described in
+include/uapi/linux/dm365_ipipeif.h
+
+The VIDIOC_VPFE_IPIPEIF_S_CONFIG is used to configure the ipipeif
+hardware block. The VIDIOC_VPFE_IPIPEIF_S_CONFIG and
+VIDIOC_VPFE_IPIPEIF_G_CONFIG accepts a pointer to struct ipipeif_params
+as its argument.
+

+ * Driver name : VPFE Capture driver
+ * VPFE Capture driver allows applications to capture and stream video
+ * frames on DaVinci SoCs (DM6446, DM355 etc) from a YUV source such as
+ * TVP5146 or Raw Bayer RGB image data from an image sensor
+ * such as Microns' MT9T001, MT9T031 etc.
+ *
+ * These SoCs have, in common, a Video Processing Subsystem (VPSS) that
+ * consists of a Video Processing Front End (VPFE) for capturing
+ * video/raw image data and Video Processing Back End (VPBE) for displaying
+ * YUV data through an in-built analog encoder or Digital LCD port. This
+ * driver is for capture through VPFE. A typical EVM using these SoCs have
+ * following high level configuration.
+ *
+ * decoder(TVP5146/ YUV/
+ * MT9T001) --> Raw Bayer RGB ---> MUX -> VPFE (CCDC/ISIF)
+ * data input | |
+ * V |
+ * SDRAM |
+ * V
+ * Image Processor
+ * |
+ * V
+ * SDRAM
+ * The data flow happens from a decoder connected to the VPFE over a
+ * YUV embedded (BT.656/BT.1120) or separate sync or raw bayer rgb interface
+ * and to the input of VPFE through an optional MUX (if more inputs are
+ * to be interfaced on the EVM). The input data is first passed through
+ * CCDC (CCD Controller, a.k.a Image Sensor Interface, ISIF). The CCDC
+ * does very little or no processing on YUV data and does pre-process Raw
+ * Bayer RGB data through modules such as Defect Pixel Correction (DFC)
+ * Color Space Conversion (CSC), data gain/offset etc. After this, data
+ * can be written to SDRAM or can be connected to the image processing
+ * block such as IPIPE (on DM355/DM365 only).
+ *
+ * Features supported
+ * - MMAP IO
+ * - USERPTR IO
+ * - Capture using TVP5146 over BT.656
+ * - Support for interfacing decoders using sub device model
+ * - Work with DM365 or DM355 or DM6446 CCDC to do Raw Bayer
+ * RGB/YUV data capture to SDRAM.
+ * - Chaining of Image Processor
+ * - SINGLE-SHOT mode

ToDo list (incomplete, unordered)
- add compile as module support
- - fix clk usage
- should not be using clk_get_sys(), but clk_get(&pdev->dev, conn)
- where conn is either NULL if the device only has one clock, or
- the device specific name if it has multiple clocks.
- move half of the nvec init stuff to i2c-tegra.c
- move event handling to nvec_events
- finish suspend/resume support

-TODO
-. add video decode/encode support (via syslink3 + codec-engine)
- . NOTE: with dmabuf this probably could be split into different driver
- so perhaps this TODO doesn't belong here
-. where should we do eviction (detatch_pages())? We aren't necessarily
- accessing the pages via a GART, so maybe we need some other threshold
- to put a cap on the # of pages that can be pin'd. (It is mostly only
- of interest in case you have a swap partition/file.. which a lot of
- these devices do not.. but it doesn't hurt for the driver to do the
- right thing anyways.)
- . Use mm_shrinker to trigger unpinning pages. Need to figure out how
- to handle next issue first (I think?)
- . Note TTM already has some mm_shrinker stuff.. maybe an argument to
- move to TTM? Or maybe something that could be factored out in common?
-. GEM/shmem backed pages can have existing mappings (kernel linear map,
- etc..), which isn't really ideal.
-. Revisit GEM sync object infrastructure.. TTM has some framework for this
- already. Possibly this could be refactored out and made more common?
- There should be some way to do this with less wheel-reinvention.
-. Solve PM sequencing on resume. DMM/TILER must be reloaded before any
- access is made from any component in the system. Which means on suspend
- CRTC's should be disabled, and on resume the LUT should be reprogrammed
- before CRTC's are re-enabled, to prevent DSS from trying to DMA from a
- buffer mapped in DMM/TILER before LUT is reloaded.

- Zcache2 doubles RAM efficiency while providing a significant
- performance boosts on many workloads. Zcache2 uses
- compression and an in-kernel implementation of transcendent
- memory to store clean page cache pages and swap in RAM,
- providing a noticeable reduction in disk I/O. Zcache2
- is a complete rewrite of the older zcache; it was intended to
- be a merge but that has been blocked due to political and
- technical disagreements. It is intended that they will merge
- again in the future. Until then, zcache2 is a single-node
- version of ramster.

- help
- RAMster allows RAM on other machines in a cluster to be utilized
- dynamically and symmetrically instead of swapping to a local swap
- disk, thus improving performance on memory-constrained workloads
- while minimizing total RAM across the cluster. RAMster, like
- zcache2, compresses swap pages into local RAM, but then remotifies
- the compressed pages to another node in the RAMster cluster.

- * In-kernel transcendent memory (generic implementation)
- *
- * Copyright (c) 2009-2012, Dan Magenheimer, Oracle Corp.
- *
- * The primary purpose of Transcedent Memory ("tmem") is to map object-oriented
- * "handles" (triples containing a pool id, and object id, and an index), to
- * pages in a page-accessible memory (PAM). Tmem references the PAM pages via
- * an abstract "pampd" (PAM page-descriptor), which can be operated on by a
- * set of functions (pamops). Each pampd contains some representation of
- * PAGE_SIZE bytes worth of data. For those familiar with key-value stores,
- * the tmem handle is a three-level hierarchical key, and the value is always
- * reconstituted (but not necessarily stored) as PAGE_SIZE bytes and is
- * referenced in the datastore by the pampd. The hierarchy is required
- * to ensure that certain invalidation functions can be performed efficiently
- * (i.e. flush all indexes associated with this object_id, or
- * flush all objects associated with this pool).
- *
- * Tmem must support potentially millions of pages and must be able to insert,
- * find, and delete these pages at a potential frequency of thousands per
- * second concurrently across many CPUs, (and, if used with KVM, across many
- * vcpus across many guests). Tmem is tracked with a hierarchy of data
- * structures, organized by the elements in the handle-tuple: pool_id,
- * object_id, and page index. One or more "clients" (e.g. guests) each
- * provide one or more tmem_pools. Each pool, contains a hash table of
- * rb_trees of tmem_objs. Each tmem_obj contains a radix-tree-like tree
- * of pointers, with intermediate nodes called tmem_objnodes. Each leaf
- * pointer in this tree points to a pampd, which is accessible only through
- * a small set of callbacks registered by the PAM implementation (see
- * tmem_register_pamops). Tmem only needs to memory allocation for objs
- * and objnodes and this is done via a set of callbacks that must be
- * registered by the tmem host implementation (e.g. see tmem_register_hostops).

- * Zcache provides an in-kernel "host implementation" for transcendent memory
- * ("tmem") and, thus indirectly, for cleancache and frontswap. Zcache uses
- * lzo1x compression to improve density and an embedded allocator called
- * "zbud" which "buddies" two compressed pages semi-optimally in each physical
- * pageframe. Zbud is integrally tied into tmem to allow pageframes to
- * be "reclaimed" efficiently.

+** ZCACHE PLAN FOR PROMOTION FROM STAGING **
+
+Last updated: Feb 13, 2013
+
+PLAN STEPS
+
+1. merge zcache and ramster to eliminate horrible code duplication
+2. converge on a predictable, writeback-capable allocator
+3. use debugfs instead of sysfs (per akpm feedback in 2011)
+4. zcache side of cleancache/mm WasActive patch
+5. zcache side of frontswap exclusive gets
+6. zcache must be able to writeback to physical swap disk
+ (per Andrea Arcangeli feedback in 2011)
+7. implement adequate policy for writeback
+8. frontswap/cleancache work to allow zcache to be loaded
+ as a module
+9. get core mm developer to review
+10. incorporate feedback from review
+11. get review/acks from 1-2 additional mm developers
+12. incorporate any feedback from additional mm reviews
+13. propose location/file-naming in mm tree
+14. repeat 9-13 as necessary until akpm is happy and merges
+
+STATUS/OWNERSHIP
+
+1. DONE as part of "new" zcache; in staging/zcache for 3.9
+2. DONE as part of "new" zcache (cf zbud.[ch]); in staging/zcache for 3.9
+ (this was the core of the zcache1 vs zcache2 flail)
+3. DONE as part of "new" zcache; in staging/zcache for 3.9
+4. DONE (w/caveats) as part of "new" zcache; per cleancache performance
+ feedback see https://lkml.org/lkml/2011/8/17/351, in
+ staging/zcache for 3.9; dependent on proposed mm patch, see
+ https://lkml.org/lkml/2012/1/25/300
+5. DONE as part of "new" zcache; performance tuning only,
+ in staging/zcache for 3.9; dependent on frontswap patch
+ merged in 3.7 (33c2a174)
+6. DONE (w/caveats), prototyped as part of "new" zcache, had
+ bad memory leak; reimplemented to use sjennings clever tricks
+ and proposed mm patches with new version in staging/zcache
+ for 3.9, see https://lkml.org/lkml/2013/2/6/437;
+7. PROTOTYPED as part of "new" zcache; in staging/zcache for 3.9;
+ needs more review (plan to discuss at LSF/MM 2013)
+8. IN PROGRESS; owned by Konrad Wilk; v2 recently posted
+ http://lkml.org/lkml/2013/2/1/542
+9. IN PROGRESS; owned by Konrad Wilk; Mel Gorman provided
+ great feedback in August 2012 (unfortunately of "old"
+ zcache)
+10. Konrad posted series of fixes (that now need rebasing)
+ https://lkml.org/lkml/2013/2/1/566
+11. NOT DONE; owned by Konrad Wilk
+12. TBD (depends on quantity of feedback)
+13. PROPOSED; one suggestion proposed by Dan; needs more ideas/feedback
+14. TBD (depends on feedback)
+
+WHO NEEDS TO AGREE
+
+Not sure. Seth Jennings is now pursuing a separate but semi-parallel
+track. Akpm clearly has to approve for any mm merge to happen. Minchan
+Kim has interest but may be happy if/when zram is merged into mm. Konrad
+Wilk may be maintainer if akpm decides compression is maintainable
+separately from the rest of mm. (More LSF/MM 2013 discussion.)
+
+ZCACHE FUTURE NEW FUNCTIONALITY
+
+A. Support zsmalloc as an alternative high-density allocator
+ (See https://lkml.org/lkml/2013/1/23/511)
+B. Support zero-filled pages more efficiently
+C. Possibly support three zbuds per pageframe when space allows

* Zcache provides an in-kernel "host implementation" for transcendent memory
- * and, thus indirectly, for cleancache and frontswap. Zcache includes two
- * page-accessible memory [1] interfaces, both utilizing the crypto compression
- * API:
- * 1) "compression buddies" ("zbud") is used for ephemeral pages
- * 2) zsmalloc is used for persistent pages.
- * Xvmalloc (based on the TLSF allocator) has very low fragmentation
- * so maximizes space efficiency, while zbud allows pairs (and potentially,
- * in the future, more than a pair of) compressed pages to be closely linked
- * so that reclaiming can be done via the kernel's physical-page-oriented
- * "shrinker" interface.
- *
- * [1] For a definition of page-accessible memory (aka PAM), see:
- * http://marc.info/?l=linux-mm&m=127811271605009
+ * ("tmem") and, thus indirectly, for cleancache and frontswap. Zcache uses
+ * lzo1x compression to improve density and an embedded allocator called
+ * "zbud" which "buddies" two compressed pages semi-optimally in each physical
+ * pageframe. Zbud is integrally tied into tmem to allow pageframes to
+ * be "reclaimed" efficiently.
