- 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.

Adapted from patch Bar³omiej ¯o³nierkiewicz: - make straight8 a flag in ata_channel instead of byte - don't store tables as code in drive_is_flashcard() and ide_xfer_verbose() - fix init_gendisk() (due to 2.5.13 blksize_size[] change) - compress region requesting/releasing in channel_probe() and ide_unregister() - clean a bit ide_setup_ports() Start of DMA handling tratment. - Fix the parameters to ide_build_dmatable() to be channel and request. Rename it to udma_new_table(). udma will mark arch specific functions later. - Let ide_start_dma() take the request directly as an arguemnt. Rename it to ata_start_dma(). After realizing that the usage of the func argument of it was bogous and that nobody is using rwproc we where able to remove both of them. - Fix ide_destroy_dmatable() to take the channel as argument and rename it to udma_destroy_table(). This function should have possible architecture specific implementation as well at some point in time. - Split up the TCQ UDMA handling stuff in to proper functions. Jens must has been dreaming as he introduced them ;-).

- Synchronize with Jens. Applying tons of janitorian stuff to his TCQ code. Making functions static where appropriate and so on... Marking the config entry for it experimental and so on. His changelog: 2.5.13 now has the generic tag support that I wrote included, here's an IDE TCQ that uses that. Changes since the version posted for 2.5.12: Fix the ide_tcq_invalidate_queue() WIN_NOP usage needed to clear the internal queue on errors. It was disabled in the last version due to the ata_request changes, it should work now. Remove Promise tcq disable check, it works just fine on Promise as long as we handle the two-drives-with-tcq case like we currently do.

- Revoke the TCQ stuff. Well having it for some time showed just nicely what has to be done before it can be included cleanly. But it's just not ready yet. For more explanations please simply track the usage of the special field of struct request - *both* in the generic request handling code and in overall driver code.

- Integrate the TCQ stuff from Jens Axboe. Deal with the conflicts, apply some cosmetic changes. We are still not at a stage where we could immediately integrate ata_request and ata_taskfile but we are no longer far away. - Clean up the data transfer function in ide-disk to use ata_request structures directly. - Kill useless leading version information in ide-disk.c - Replace the ATA_AR_INIT macro with inline ata_ar_init() function. - Replace IDE_CLEAR_TAG with ata_clear_tag(). - Replace IDE_SET_TAG with ata_set_tag(). - Kill georgeous ide_dmafunc_verbose(). - Fix typo in ide_enable_queued() (ide-tcq.c!) Apparently there still problems with a TCQ enabled device and a not enabled device on the same channel, but let's first synchronize up with Jens.

- 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.

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...

1. Kill the ide-probe-mod by merging it with ide-mod. There is *really* no reaons for having this stuff split up into two different modules unless you wan't to create artificial module dependancies and waste space of page boundaries during memmory allocation for the modules 2. Kill the ide_module_t - which is unnecessary and presents a "reimplementation" of module handling inside the ide driver. This is achieved by attaching the initialization routine ot the ide_driver_t, which will be gone next time, since there is no sane reason apparently, which this couldn't be done during the module-generic initialization of the corresponding driver module. 3. Kill unnecessary tagging of "subdriver" with IDE_SUBDRIVER_VERSION - we have plenty of other mechanisms for module consistency checking. And anyway the ide code didn't any consistence checks on this value at all. NOTE: The ide_(un)register_module() functions will be killed in next round.
