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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Heo2007-10-292-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | | libata: relocate and fix post-command processingTejun Heo2007-10-292-23/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
