* [PATCH] move ->eh_strategy_handler to the transport classChristoph Hellwig2006-04-101-1/+0
| | | | | | | | | | | | | Overriding the whole EH code is a per-transport, not per-host thing. Move ->eh_strategy_handler to the transport class, same as ->eh_timed_out. Downside is that scsi_host_alloc can't check for the total lack of EH anymore, but the transition period from old EH where we needed it is long gone already.

* [PATCH] libata: make per-dev transfer mode limits per-devTejun Heo2006-03-241-1/+1
| | | | | | | | Now that each ata_device has xfer masks, per-dev limits can be made per-dev instead of per-port. Make per-dev limits per-dev. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [SCSI] libata: implement minimal transport template for ->eh_timed_outTejun Heo2006-03-211-1/+0
| | | | | | | | | | SCSI midlayer has moved hostt->eh_timed_out to transport template. As libata doesn't need full-blown transport support yet, implement minimal transport for libata. No transport class or whatsoever, just empty transport template with ->eh_timed_out hook. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| * [PATCH] sata_sil: implement R_ERR on DMA activate FIS errata fixTejun Heo2006-02-251-6/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Silicon Image has disclosed a new sil3114/3152 errata and workaround which causes the controller to return R_ERR on DMA activate FIS if the FIS is received while the next PRD is being fetched. This patch implements the workaround. This errata results in lock up and doesn't trigger if m15w workaround is in effect. We stopped applying m15w to 3512 and 3114 in 2.6.14-rc1 which makes 3512/3114 lock up with some drives on all kernel versions since 2.6.14-rc1 upto now (2.6.16-rc4). This patch should fix the regression. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* | [PATCH] libata: add per-device max_sectorsTejun Heo2006-02-121-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a low level driver wants to control max_sectors, it had to adjust ap->host->max_sectors and set ATA_DFLAG_LOCK_SECTORS to tell ata_scsi_slave_config not to override the limit. This is not only cumbersome but also incorrect for hosts which support more than one devices per port. This patch adds per-device ->max_sectors. If the field is unset (zero), libata core layer will adjust ->max_sectors according to default rules. If the field is set, libata honors the setting.

* [libata sata_sil] implement 'slow_down' module parameterJeff Garzik2006-01-271-2/+8
| | | | | | | | | | | | | | | | | | | On occasion, a user will submit a patch that enables the "mod15write" quirk for their device. Enabling this quirk has the effect of clamping all ATA commands to no more than 15 sectors. The intended use of this quirk is to stop the controller from generating FIS's of unusual size ("but Wesley, what about the FOUS's?"), which in turn works around problems in a <list> of hard drives. One side effect of this quirk is greatly decreased performance. Users often enable the mod15write quirk to fix various system, power, chip, and/or driver problems. For a few rare problematic cases, enabling this has cured lockups or data corruption. Rather than add bogus listings to the mod15write quirk list (I get a patch every month doing such), we add a 'slow_down' module parameter. This allows users to employ a performance sledgehammer in the hopes of curing a problem. It defaults to off (0), of course.

| * [PATCH] sil: apply M15W quirk selectively (take 2)Tejun Heo2005-08-231-7/+20
| | | | | | | | | | | | | | | | | | | | | | | | As SII reports that only original 3112's are affected by M15W quirk, This patch adds SIL_FLAG_MOD15WRITE to selectively apply M15W quirk depending on chipsets. As of yet, we don't know exactly which PCI IDs are for original 3112, so M15W quirk is applied to all except for 3512 and 3124. Once more info is avaliable, we can change some of these sil_3112_m15w's to sil_3112. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

* libata: Fix use-after-iounmapJeff Garzik2005-05-261-0/+1
| | | | | | | | | | | | | | | | | | Jens Axboe pointed out that the iounmap() call in libata was occurring too early, and some drivers (ahci, probably others) were using ioremap'd memory after it had been unmapped. The patch should address that problem by way of improving the libata driver API: * move ->host_stop() call after all ->port_stop() calls have occurred. * create default helper function ata_host_stop(), and move iounmap() call there. * add ->host_stop_prewalk() hook, use it in sata_qstor.c (hi Mark). sata_qstor appears to require the host-stop-before-port-stop ordering that existed prior to applying the attached patch.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
