2005-10-30[libata] ata_tf_to_host cleanupsJeff Garzik
Integrate ata_exec() and ata_tf_to_host() into their only caller, ata_bus_edd(). Rename ata_tf_to_host_nolock() to ata_tf_to_host(). This makes locking a bit easier to review, and may help pave the way for future changes.
2005-10-30[libata] change ata_qc_complete() to take error mask as second argJeff Garzik
The second argument to ata_qc_complete() was being used for two purposes: communicate the ATA Status register to the completion function, and indicate an error. On legacy PCI IDE hardware, the latter is often implicit in the former. On more modern hardware, the driver often completely emulated a Status register value, passing ATA_ERR as an indication that something went wrong. Now that previous code changes have eliminated the need to use drv_stat arg to communicate the ATA Status register value, we can convert it to a mask of possible error classes. This will lead to more flexible error handling in the future.

2005-10-22libata: const-ification bombing runJeff Garzik
Enforce access rules where appropriate. If the compiler is smart enough, this may buy us an optimization or two as a side effect.

2005-10-18[PATCH] libata CHS: calculate read/write commands and protocol on the fly ↵Albert Lee
(revise #6) - merge ata_prot_to_cmd() and ata_dev_set_protocol() as ata_rwcmd_protocol() - pave road for read/write multiple support - remove usage of pre-cached command and protocol values and call ata_rwcmd_protocol() instead Signed-off-by: Albert Lee <albertcc@tw.ibm.com> ============== Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2005-10-09[libata scsi] improve scsi error handling with ata_scsi_set_sense()Douglas Gilbert
- change "xlat" and "fill" actors in libata-scsi so they are responsible for SCSI status and sense data when they return 1. This allows GOOD status or a specialized error to be set. - yield an error for mode sense requests for saved values [sat-r06] - remove static inlines for ata_bad_scsiop() and ata_bad_cdb() which are no longer used Signed-off-by: Douglas Gilbert <dougg@torque.net> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-10-09[libata scsi] add ata_scsi_set_sense helperDouglas Gilbert

2005-10-05libata: move atapi_request_sense() to libata-scsi moduleJeff Garzik
No content changes, just moving code around.
2005-10-03[libata] improve device scanJeff Garzik
Replace SCSI's legacy "bang at the door" method of probing with one directly controlled by the underlying ATA transport layer. We now only call scsi_scan_target() for devices we find, rather than probing every possible channel/id within a certain range.

2005-08-30[libata] allow ATAPI to be enabled with new atapi_enabled module optionJeff Garzik
ATAPI is getting close to being ready. To increase exposure, we enable the code in the upstream kernel, but default it to off (present behavior). Users must pass atapi_enabled=1 as a module option (if module) or on the kernel command line (if built in) to turn on discovery of their ATAPI devices.

2005-08-28[libata] license change, other bitsJeff Garzik
- changes license of all code from OSL+GPL to plain ole GPL - except for NVIDIA, who hasn't yet responded about sata_nv - copyright holders were already contacted privately - adds info in each driver about where hardware/protocol docs may be obtained - where I have made major contributions, updated copyright dates

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
