      [PATCH] alpha: common ev6/ev7 machine check handler · 353cc80d
      Ivan Kokshaysky authored
      Here is new ev6/ev7 machine check parser, which is a part of Jeff's
      titan/marvel patchset.
      Instead of fixing nautilus machine check handler, I've converted it
      to use this new code.  Works fine.
      Also, the CONFIG_VERBOSE_MCHECK is good for cia/pyxis - the detailed
      error reporting is completely useless unless you have faulty CPU or RAM.
      
      Ivan.

      [PATCH] 2.5.17 IDE 67 · 14cfb6a6
      Martin Dalecki authored
       - Nuke COMMERIAL and similar spurious configuration options...
         The fact that every single default configuration option contained
         those bits makes this trivial patch appear rather big.

      [PATCH] 2.5.15 IDE 63 · d7e09f7e
      Martin Dalecki authored
      - Propagate the queue handling changes to pmac as well.
      
      - Move set_transfer to ide-taskfile.c this is the only place where it's used
         and it can be made static there. Same applies to ide_ata66_check().
      
      - Move ide_auto_reduce_xfer to ide.c.
      
      - Make ide_cmd() local to the only place where it's used. Rename it to
         drive_cmd(). Don't pass drive_cmd_intr() as parameter.
      
      - Remove ide_next command completion type. Nobody is using it.
      
      - Move ide_do_drive_cmd to ide-taskfile. It's used there and in sub-drivers.
         Not in ide.c. The usage inside the device type drivers is entirely bogus
         inconsistent and so on...
      
      - Kill bogus IRQ masking code. The kernel is supposed to handle this properly.
         We should not try to work against possible bugs in the overall irq handling
         code. Wow this is increasing the systems overall responsibility by a
         significant margin.
      
      - Remove disfunctional pdcadma code. It is only misleading to the user.

      [PATCH] 2.5.14 IDE 55 · fb0bbfda
      Martin Dalecki authored
       - Update HPT374 driver carried over from 2.4.xx series by Andrew Morton.
         Resync it with the recent host chip driver changes, or better the
         introduction of an API at all.
      
       - Consolidate the handling of device ID byte order in one place.
         This was spotted and patched by Bartomiej onierkiewicz.
      
       - Eliminate CONFIG_BLK_DEV_IDEPCI - it's duplicating the functionality of the
         already present and fine CONFIG_PCI flag and if we are a PCI host, we are
         indeed very likely to need host chip support anyway.
      
       - Remove some redundant info about the model and channel number from
         /proc/ide. Remove the binary entries not helpful to the user, and not used
         by any program and redundant to corresponding ioctls.
      
       - Properly return udma_read and udma_write values in taskfile.
      
       - Only initialize XXX_udma to the default handlers if it has not been
         initialized by the host chip initialization.
      
      I have enabled spin lock debugging and can see that on device
      flush the spin locks get wrong counts... no problems elsewher ethus
      far. I will re check them next time around.

      [PATCH] 2.5.11 IDE 46 · 4a58bd1a
      Martin Dalecki authored
      - Remove the specific CONFIG_IDEDMA_PCI_WIP in favor of using the generic
         CONFIG_EXPERIMENTAL tag. (Pointed out by Vojtech Pavlik).
      
      - Change the signature of the IRQ handler to take the request directly as a
         parameter. This doesn't blow the code up but makes it much more obvious and
         finally it's reducing the number of side effects of the hwgroup->rq field.
      
      - A second sharp look after the above change allowed us to remove the wrq field
         from the hwgroup struct. It's just not used at all.
      
      - Change the signature of the end_request member of struct ata_operations to
         take the request as a second argument. Similar for __ide_end_request()
         and ide_end_request().
      
      - Remove BUG_ON() items just before ide_set_handler(). The check in
         ide_set_handler is clever enough now.
      
      - Remove the rq subfield from ide-scsi packet structure. We have now the
         request context always in place. Same for floppy.
      
      - Let the timer expiry function take the request as a direct argument.
      
      Yes I know those changes are extensive. But they are a necessary step
      in between for the following purposes:
      
      - Consolidate the whole ATA/ATAPI stuff on passing a single unified request
         handling object. Because after eliminating those side effects it's far easier
         to see what's passed where.
      
      - Minimizing the amount of side effects in the overall code. That's a good
         thing anyway and it *doesn't* cost us neither performance nor space, since
         the stack depths are small anyway here.
      
      - Minimizing the usage of hwgroup - which should go away if possible.

      [PATCH] 2.5.7-pre2 IDE 22a · 198231a8
      Martin Dalecki authored
      - Apply more patches from Vojtech Pavlik for the handling of host chip setup.
         Hopefully they are settled now.
      
      - Kill unused CONFIG_BLK_DEV_MODES
      
      - Push register addressing down in to task_vlb_sync.
      
      - Make the taskfile parsing stuff actually readable. This is compressing the
         code by an incredible amount. We use just one function doing the whole
         scanning right now. This should make sure that the IRQ handler used by a
         particular command is always right.  I didn't introduce typos hopefully
         here.
      
      - Don't call ide_handler_parser as argument for do_taskfile() any longer. We
         have killed this function by coalescing it's functionality with
         ide_cmd_type_parser() anyway.
      
      - Kill unused SLC90E66 code, which Vojtech apparently missed in his patch.
      
      - sync up with 2.5.7-pre2
      
      Once again the actual patch is rather big mostly due to the removal of
      some default configuration variables which are not used anylonger. So time for
      the next patch stage.

      If I was to give this patch a name it would be:
      
      "Vojtech Pavlik unleashed from the chains".
      
      So credit where credit is due :-).
      
      Anyway here follows the change log:
      
      Mon Mar 11 23:48:28 CET 2002 ide-clean-21
      
      - Swallow rewritten amd74xx host chip setup code from Vojtech Pavlik.  We can
         revert it easly if it turns out to be a bad thing. However the code looks
         quite sane to me. In esp. it doesn't containg that many magic numbers.
      
      - Clean stale white spaces in ide-timing.h tirvial fix.
      
      - Make ide_release_dma return void. It's value is never used anyway.
      
      - Swallow more timing setup code cleanup by Vojtech Pavlik. Apply some
         cosmetics to it. Port opti621 to the new setup code.
      
      - Kill abuse of ide_do_reset() on error return paths for atapi floppy tape and
         cd-rom devices. Just stop them. This gives better changes that defect
         removable media will not cause suddenly broken timings on hard discs
         containing system data! Even then comments in ide_do_reset() admit, that
         resetting the whole channel can have adverse effects on the second interface
         on this channel. And I have too frequently observed linux struggling on
         defect cd-rom for a far too long time to wish it to continue.
      
         Oh did I forget to say that the corresponding "how can I break my system fast
         and reliable" ioctl is gone as well?
      
         Removing it recovered the fact that the CONFIG_BLK_DEV_IDEDMA_TIMEOUT is
         completely bogous. I have removed this option therefore as well, because it's
         playing the same wrack havoc on the devices if enabled. This cat has been in
         an unfinished and *unfunctional* state anyway.
      
      - Actually add physical suspend code to the power handling code.  Still the
         resume code isn't finished just jet. This is all subject to change at the
         point in time when we get to proper command queueing.
         I think however that Pavel will be interrested in tidding this bit up...
      
      - Resync with 2.5.7-pre1.

      [PATCH] 2.5.6 IDE 18 · 4dabe948
      Martin Dalecki authored
      No fixes for new problems which occured since today, just syncup.
      
       - Remove help text about suitable compiler versions, which is obsoleted
         by the overall kernel reality.
      
       - Remove traces of not progressing work in progress code for the
         CONFIG_BLK_DEV_ADMA option as well as the empty ide-adma.c file as
         well as CONFIG_BLK_DEV_IDEDMA_TCQ.
      
       - Remove redundant CONFIG_BLK_DEV_IDE != n check in ide/Config.in. Hugh,
         this is a tricky one...
      
       - Add EXPORT_SYMBOL(ide_fops) again, since it's used in ide-cd.c add a
         note there that this is actually possibly adding the same device twice
         to the devfs stuff.
      
       - Finally change the MAINTAINER entry. Just too many persons bogged me
         about it and it doesn't take me too much time apparently.
      
       - Apply sis.patch.20020304_1.
      
       - Don't call ide_release_dma twice in cleanup_ata, since ide_unregister
         is already calling it for us. Change prototype of ide_unregister to
         take a hwif as parameter and disable an ioctl for removing/scanning
         hwif from the list of handled interfaces. I see no reasons for having
         it and doing it is the fastest DOS attack on my home system I know
         about it. Contrary to the comments found here and there, hdparm
         doesn't use it. There are better hot plugging interfaces coming to the
         kernel right now anyway.
      
       - Wrap invalidate_drives in ide_unregister under the ide_lock instead of
         disabling and enabling interrupts during this operation. There are
         plenty of other places where the IDE drivers are enabling and
         disabling interrupts just to protect some data structures.
      
       - Don't call destroy_proc_ide_drives(hwif) for every single drive out
         there.This routine takes a hwif as a parameter.
      
       - Resync with the instable 2.5.6...

      [PATCH] IDE 17 (not just cleanup) · a925c40f
      Martin Dalecki authored
      This is actually an attempt to remove some stall code from
      this driver. However if some *real* users complain (Not just
      the usuall: "Hey - if someone!" but the "Hey I'm using this!")
      I'm all open to reenable it. Since I prepared this patch
      yerstoday it doesn't contain the ide_module.h fixup. This will
      follow later.
      
      - Don't use the convoluted byte type in ide-pci.c. Just use the proper
         u8instead.
      
      - Move ide_get_or_set_dma_base to the only place where it's used and
         reorganize the code there by killing the unnecessary
         CONFIG_BLK_DEV_IDEDMA_FORCED configuration option.
      
      - Remove unfunctional CONFIG_PKT_TASK_IOCTL code.
      
      - Kill unused ALTSTAT_SCREW_UP code.
      
      - Tons of dead code removed from ide-taskfile.c (#if 0 #endif and
         friends)
      
      - Remove unused IDE_DEBUG macro as well as lots of other name space
         pollution from ide.h.
      
      - Start using the ide_lock spin-lock for protecting access to data
         structures instead of the excessive interrupt disabling games.
      
      - Shorten the proc ouput of the piix initialization module.
      
      - Remove special /proc tape "name" output from ide-tape.c. This was
         redundant data which should only show up on syslog anyway.
      
      - Kill the REALLY_FAST_IO undef from the ide.h. This was a mistake
         present since far too many years in this driver. The proper way to
         deal with broken systems is to define REALLY_SLOW_IO in system
         dependent headers or particular driver files.  We can always
         reintroduce it easy if real users will complain, since OUT_BYTE() and
         similar can be used as hooks. But I don't expect anybody reporting
         about this. Even on the most broken IDE chip in the world (cmd640
         at VLB) undefining this *always* worked for me. Nearly all the code
         pieces in the ide driver code *reverted* it's effects explicitly
         anyway.
      
      - Remove the obsolete CONFIG_BLK_DEV_4DRIVES support. This was supposed
         to support 4 drivers attached at one channel on some older chipsets,
         in esp. Tekram 690CD, in the last century. They where all supposed to
         work at a register set starting at the base address 0x1f0.  Before
         complaining that this is removing functionality, please note that this
         must have been broken for already quite a long time, since the ide
         driver didn't contain the special device selection methods implicated
         by this any longer.  It didn't scan   this port too if PCI host chip
         support was enabled (as it is in all those distributions around
         there).  On the other hand this is the most prominent case of
         incoherent use of the mate member in the struct hwif_s. And please
         think about how big the probability is, that there are systems out
         there, where there are actually 4 drivers on such a channel?
      
      - Streamline module initialization code by removing one shoot functions.
      
      - Make the WAIT_READY value used in case of CONFIG_APM or
         CONFIG_APM_MODULE the default, since this is what really reflects the
         behavior of modern drives. It won't hurt any other case and finally
         removing it is reducing the necessary coverage for overall driver code
         testing/analysis.
      
      - Move the IDE_LARGE_SEEK macro to the only place where it's actually
         used. Replace the IDE_MIN() and IDE_MAX() drivers with the obvious.
         Remove unused SPLIT_WORD and MAKE WORD from the local header.
      
      - Remove CMD640_DUMP_REGS from global scope, since there is no
         development done on this any longer. Finally, the way the host chip
         initialization routines are called changed in the time between allows
         this to remain fully local to the host chip driver in question.
      
      - Some spell checking of comments in the code. (Yeep I have extended my
         Vim to do this the "Word" way with nice undercurl lines... mozilla
         remains to be fixed...)

      [PATCH] 2.5.6-pre2 IDE cleanup 16 · 24ae9cff
      Martin Dalecki authored
      There is no such a thing like a ide-clean-15. Never was.  But here comes
      what has been done in ide-clean-16:
      
      - Apply a patch for the initialization of the second PIIX channel.
         Found by Daniel Quinlan <quinlan@transmeta.com>
      
      - Apply a patch for the DMA initialization of the serverworks chip.
         Ken Brownfield <brownfld@irridia.com>
      
      - Make the ata_operations methods immune against device type drivers,
         which donot provide them by separating the access to them out. Audit
         them all.
      
      - Resynchronize with 2.5.6-pre1.
      
      - Remove unused IDE_DRIVE_CMD, IDE_DRIVE_TASK, IDE_DRIVE_TASK_MASK,
         IDE_DRIVE_TASKFILE macros.
      
      - Disable configuration of the task file stuff. It is going to go away
         and will be replaced by a truly abstract interface based on
         functionality and *not* direct mess-up of hardware.
      
      - Resync with 2.5.6-pre2.
      
      - Add HPT entries to the fall-back list, since otherwise the driver
         won'trecognize the drives. We will have to make this the default
         behavior for allnot recognized host chip types.
      
      - Fix compilation with no PCI host chip support enabled.
      
      - Apply the overflow fixes for HPT366 by Vojtech Pavlik.
      
      - Kill the one-shoot functions ide_wait_cmd_taks() ide_wait_cmd() by
         moving them to the places where they are actually used. Fix a
         potential buffer overflow on the way.
      
      - Fix usage of ide.c as module. Thanks to Adam J. Richter for figuring
         out what was wrong.
      
      - Various cleanups all along as well as removal of TONS of
         unfinished/dead code.
      
      I think it's sometimes better to remove stuff, which isn't there,
      instead of hoping for a "magical day" where it will be finished.
