2006-04-10[PATCH] move ->eh_strategy_handler to the transport classChristoph Hellwig1-1/+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.

2006-03-31[PATCH] libata: make ata_qc_issue complete failed qcsTejun Heo1-1/+1
There is no reason for the issuer to diddle with a failed qc as the issuer has complete control over when a qc gets freed (usually in ->complete_fn). Make ata_qc_issue() responsible for completing qcs which failed to issue. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-21[SCSI] libata: implement minimal transport template for ->eh_timed_outTejun Heo1-0/+2
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>
2006-03-11[PATCH] libata: implement port_taskTejun Heo1-0/+1
Implement port_task. LLDD's can schedule a function to be executed with context after specified delay. libata core takes care of synchronization against EH. This is generalized form of pio_task and packet_task which are tied to PIO hsm implementation. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-02-11[PATCH] libata: inline ata_qc_complete()Tejun Heo1-1/+0
This patch inlines ata_qc_complete() and uninlines __ata_qc_complete() as suggested by Jeff Garzik. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2006-02-10[PATCH] libata: add ATA_QCFLAG_EH_SCHEDULEDTejun Heo1-0/+1
Add ATA_QCFLAG_EH_SCHEDULED. If this flag is set, the qc is owned by EH and normal completion path is not allowed to finish it. This patch doesn't actually use this flag. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2006-01-26[PATCH] libata: return AC_ERR_* from issue functionsTejun Heo1-1/+1
Return AC_ERR_* mask from issue fuctions instead of 0/-1. This enables things like failing a qc with AC_ERR_HSM when the device doesn't set DRDY when the qc is about to be issued. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2005-12-13[PATCH] libata: remove unused functionsTejun Heo1-1/+0

2005-12-06[PATCH] libata: move err_mask to ata_queued_cmdAlbert Lee1-1/+1
- remove err_mask from the parameter list of the complete functions - move err_mask to ata_queued_cmd - initialize qc->err_mask when needed - for each function call to ata_qc_complete(), replace the err_mask parameter with qc->err_mask.

2005-11-14[libata] REQUEST SENSE handling fixesJeff Garzik1-2/+0
- Move ATAPI check-condition handling out of the timeout handler - Use multi-qc-issue feature to issue REQUEST SENSE ATAPI PACKET command upon receiving an ATAPI check-condition. This cleans things up a lot, and eliminates a nasty recursion bug.
2005-10-30[libata] ata_tf_to_host cleanupsJeff Garzik1-1/+0
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 Garzik1-1/+1
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.

Enforce access rules where appropriate. If the compiler is smart enough, this may buy us an optimization or two as a side effect.

- 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>

No content changes, just moving code around.
2005-10-03[libata] improve device scanJeff Garzik1-0/+1
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 Garzik1-0/+1
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.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+89
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!
