* libata: flush is an IO commandTejun Heo2007-10-30
| | | | | | | | | | | ATA_QCFLAG_IO is used to mark commands which are used to perform regluar IO transfers via block layer. These commands are assumed to be valid and taken more seriously during error handling. Cache flush is used by regular IO path and necessary for data integrity. Mark it with ATA_QCFLAG_IO.

* sata_promise: ASIC PRD table bug workaround, take 2Mikael Pettersson2007-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | Second-generation Promise SATA controllers have an ASIC bug which can trigger if the last PRD entry is larger than 164 bytes, resulting in intermittent errors and possible data corruption. Work around this by replacing calls to ata_qc_prep() with a private version that fills the PRD, checks the size of the last entry, and if necessary splits it to avoid the bug. Also reduce sg_tablesize by 1 to accommodate the new entry. Tested on the second-generation SATA300 TX4 and SATA300 TX2plus, and the first-generation PDC20378. Thanks to Alexander Sabourenkov for verifying the bug by studying the vendor driver, and for writing the initial patch upon which this one is based.

| * [libata] AHCI: add hw link power management supportKristen Carlson Accardi2007-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch will set the correct bits to turn on Aggressive Link Power Management (ALPM) for the ahci driver. This will cause the controller and disk to negotiate a lower power state for the link when there is no activity (see the AHCI 1.x spec for details). This feature is mutually exclusive with Hot Plug, so when ALPM is enabled, Hot Plug is disabled. ALPM will be enabled by default, but it is settable via the scsi host syfs interface. Possible settings for this feature are: Setting Effect ---------------------------------------------------------- min_power ALPM is enabled, and link set to enter lowest power state (SLUMBER) when idle Hot plug not allowed. max_performance ALPM is disabled, Hot Plug is allowed medium_power ALPM is enabled, and link set to enter second lowest power state (PARTIAL) when idle. Hot plug not allowed. Signed-off-by: Kristen Carlson Accardi <kristen.c.accardi@intel.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
| * [libata] Link power management infrastructureKristen Carlson Accardi2007-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Device Initiated Power Management, which is defined in SATA 2.5 can be enabled for disks which support it. This patch enables DIPM when the user sets the link power management policy to "min_power". Additionally, libata drivers can define a function (enable_pm) that will perform hardware specific actions to enable whatever power management policy the user set up for Host Initiated Power management (HIPM). This power management policy will be activated after all disks have been enumerated and intialized. Drivers should also define disable_pm, which will turn off link power management, but not change link power management policy. Documentation/scsi/link_power_management_policy.txt has additional information. Signed-off-by: Kristen Carlson Accardi <kristen.c.accardi@intel.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Forcing PIO0 on reset was done inside ata_bus_softreset(), which is a bit out of place as it should be applied to all resets - hard, soft and implementation which don't use ata_bus_softreset(). Relocate it such that... * For new EH, it's done in ata_eh_reset() before calling prereset. * For old EH, it's done before calling ap->ops->phy_reset() in ata_bus_probe(). This makes PIO0 forced after all resets. Another difference is that reset itself is done after PIO0 is forced.

| * libata: implement ata_wait_after_reset()Tejun Heo2007-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On certain device/controller combination, 0xff status is asserted after reset and doesn't get cleared during 150ms post-reset wait. As 0xff status is interpreted as no device (for good reasons), this can lead to misdetection on such cases. This patch implements ata_wait_after_reset() which replaces the 150ms sleep and waits upto ATA_TMOUT_FF_WAIT if status is 0xff. ATA_TMOUT_FF_WAIT is currently 800ms which is enough for HHD424020F7SV00 to get detected but not enough for Quantum GoVault drive which is known to take upto 2s. Without parallel probing, spending 2s on 0xff port would incur too much delay on ata_piix's which use 0xff to indicate empty port and doesn't have SCR register, so GoVault needs to wait till parallel probing.

| * libata: track SLEEP state and issue SRST to wake it upTejun Heo2007-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ATA devices in SLEEP mode don't respond to any commands. SRST is necessary to wake it up. Till now, when a command is issued to a device in SLEEP mode, the command times out, which makes EH reset the device and retry the command after that, causing a long delay. This patch makes libata track SLEEP state and issue SRST automatically if a command is about to be issued to a device in SLEEP.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some commands need post-processing after successful completion. This was done in ata_scsi_qc_complete() till now but this has the following problems. * Post-command processing gets executed when qc is completed from EH. Some qc's are retried from EH with zero err_mask and thus triggers unnecessary/incorrect post-command processing. * Command post processing doesn't belong to SAT layer. * Link-wide revalidation was scheduled where device revalidation suffices. This patch moves post-command processing to success completion path of ata_qc_complete() which is travelled iff the command is going to be completed without passing through EH and updates post-command processing such that device-specific action is used. While at it, restructure code a bit for readability. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| * | | | [BLOCK] Fix bad sharing of tag busy list on queues with shared tag mapsJens Axboe2007-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the locking to work, only the tag map and tag bit map may be shared (incidentally, I was just explaining this to Nick yesterday, but I apparently didn't review the code well enough myself). But we also share the busy list! The busy_list must be queue private, or we need a block_queue_tag covering lock as well. So we have to move the busy_list to the queue. This'll work fine, and it'll actually also fix a problem with blk_queue_invalidate_tags() which will invalidate tags across all shared queues. This is a bit confusing, the low level driver should call it for each queue seperately since otherwise you cannot kill tags on just a single queue for eg a hard drive that stops responding. Since the function has no callers currently, it's not an issue. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
