* [PATCH] libata-dev: Use new AC_ERR_* flagsAlbert Lee2006-02-09
| | | | | | | | | | | | - Use new AC_ERR_* flags as done in Tejun's patches - In ata_qc_timeout(), replace ac_err_mask(drv_stat) with AC_ERR_TIMEOUT. This makes time out handler always report error to upper layer. Otherwise if the drv_stat looks good, libata might falsely report OK to the upper layer.

| * [PATCH] libata: new ->probe_reset operationTejun Heo2006-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new ->probe_reset operation to ata_port_operations obsoleting ->phy_reset. The main difference from ->phy_reset is that the new operation is not allowed to manipulate libata internals directly. It's not allowed to configure or disable the port or devices. It can only succeed or fail and classify attached devices into passed @classes. This change gives more control to higher level and eases sharing reset methods with EH.

| | | | | | | | | | | | | | | | | | | | | | Implement ata_eh_qc_complete/retry() using scsi_eh_finish_cmd() and scsi_eh_flush_done_q().

| | | | | | | | | | | | | | | | | | Return AC_ERR_* mask from issue fuctions instead of 0/-1.

| * [PATCH] libata: add detailed AC_ERR_* flagsTejun Heo2006-01-26
| | | | | | | | | | | | | | | | | | | | | | Add detailed AC_ERR_* flags and use them. Long-term goal is to describe all errors with err_mask and tf combination (tf for failed sector information, etc...). After proper error diagnosis is implemented, sense data should also be generated from err_mask instead of directly from hardware tf registers as it is currently.

| * [PATCH] libata: fix ata_qc_issue() error handlingTejun Heo2006-01-26
| | | | | | | | | | | | | | | | | | | | When ata_qc_issue() fails, the qc might have been dma mapped or not. So, performing only ata_qc_free() results in dma map leak. This patch makes ata_qc_issue() mark dma map flags correctly on failure and calls ata_qc_complete() after ata_qc_issue() fails.

| * [PATCH] libata: make the owner of a qc responsible for freeing itTejun Heo2006-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | qc used to be freed automatically on command completion. However, as a qc can carry information about its completion status, it can be useful to its owner/issuer after command completion. This patch makes freeing qc responsibility of its owner. This simplifies ata_exec_internal() and makes command turn-around for atapi request sensing less hackish. This change was originally suggested by Jeff Garzik.

This patch makes ata_piix interpret MV properly on ICH6/7. Pre-ICH6/7 The value of these bits indicate the address range the SATA port responds to, and whether or not the SATA and IDE functions are combined. 000 = Non-combined. P0 is primary master. P1 is secondary master. 001 = Non-combined. P0 is secondary master. P1 is primary master. 100 = Combined. P0 is primary master. P1 is primary slave. P-ATA is 2:0 Map Value secondary. 101 = Combined. P0 is primary slave. P1 is primary master. P-ATA is secondary. 110 = Combined. P-ATA is primary. P0 is secondary master. P1 is secondary slave. 111 = Combined. P-ATA is primary. P0 is secondary slave. P1 is secondary master. ICH6/7 Map Value - R/W. Map Value (MV): The value in the bits below indicate the address range the SATA ports responds to, and whether or not the PATA and SATA functions are combined. When in combined mode, the AHCI memory space is not available and AHCI may not be used. 00 = Non-combined. P0 is primary master, P2 is the primary slave. P1 is secondary master, P3 is the 1:0 secondary slave (desktop only). P0 is primary master, P2 is the primary slave (mobile only). 01 = Combined. IDE is primary. P1 is secondary master, P3 is the secondary slave. (desktop only) 10 = Combined. P0 is primary master. P2 is primary slave. IDE is secondary 11 = Reserved Signed-off-by: Tejun Heo <htejun@gmail.com> -- Jeff, without this patch, ata_piix misdetects my ICH7's combined mode, ending up not applying bridge limits to PX-710SA and configuring IDE drive on 40-c cable to UDMA/66.
