* [SCSI] libsas: async ata scanningDan Williams2012-02-293-16/+32
| | | | | | | | | | | | | | | | | | libsas ata error handling is already async but this does not help the scan case. Move initial link recovery out from under host->scan_mutex, and delay synchronization with eh until after all port probe/recovery work has been queued. Device ordering is maintained with scan order by still calling sas_rphy_add() in order of domain discovery. Since we now scan the domain list when invoking libata-eh we need to be careful to check for fully initialized ata ports.

* [SCSI] libsas: execute transport link resets with libata-eh via host workqueueDan Williams2012-02-192-1/+1
| | | | | | | | | | | | | | | | | Link resets leave ata affiliations intact, so arrange for libsas to make an effort to avoid dropping the device due to a slow-to-recover link. Towards this end carry out reset in the host workqueue so that it can check for ata devices and kick the reset request to libata. Hard resets, in contrast, bypass libata since they are meant for associating an ata device with another initiator in the domain (tears down affiliations). Need to add a new transport_sas_phy_reset() since the current sas_phy_reset() is a utility function to libsas lldds. They are not prepared for it to loop back into eh.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The author of this driver clearly wasn't familiar with the BMIDE specification (also known as SFF-8038i) when he implemented the bmdma_status() method: first, the interrupt bit of the BMIDE status register corresponds to nothing else but INTRQ signal (ATAPI_DEV_INT here); second, the error bit is only set if the controller encounters issue doing the bus master transfers, not on the IDE DMA burst termination interrupts like here (moreover, setting the error bit doesn't cause an interrupt). We now need to disable all those unused interrupts... (The only thing I couldn't figure out is how to flush the FIFO to memory once the interrupt happens as required by the mentioned spec.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the device tree of ata port and scsi host looks as below, /sys/devices/pci0000:00/0000:00:1f.2 (ahci controller) |-- ata1 (ata port) |-- host0 (scsi host) |-- target0:0:0 (scsi target) |-- 0:0:0:0 (disk) This patch makes ata port as parent device of scsi host, then it becomes /sys/devices/pci0000:00/0000:00:1f.2 (ahci controller) |-- ata1 (ata port) |-- host0 (scsi host) |-- target0:0:0 (scsi target) |-- 0:0:0:0 (disk) With this change, the ata port runtime PM is easier.

| * ahci: start engine only during soft/hard resetsTejun Heo2012-01-091-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is another attempt at fixing the same problem that 270dac35c2 (libata: ahci_start_engine compliant to AHCI spec) tried to solve. Unfortunately, 270dac35c2 created regressions for a lot more common controllers and got reverted. This specific AHCI IP block becomes a brick if the DMA engine is started while DRQ is set. It is not possible to avoid the condition completely but the most common occurrence is caused by spurious use of ahci_start_engine() from ahci_start_port() during init sequence. DMA engine is started after both soft and hard resets and ahci_start_port() is always followed by resets, so there is no reason to start DMA engine from ahci_start_port(). This patch removes ahci_start_engine() invocation from ahci_start_port(). This change makes failure path of ahci_port_suspend() leave engine stopped without following resets. This is resolved by replacing ahci_start_port() call with ata_port_freeze() which forces resets afterwards, which is the better behavior anyway.

| * [SCSI] libsas,libata: fix ->change_queue_{depth|type} for sata devicesDan Williams2011-10-022-15/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Pass queue_depth change requests to libata, and prevent queue_type changes for ATA devices. Otherwise: 1/ we do not honor the libata specific restrictions on the queue depth 2/ libsas drivers that do not set sdev->tagged_supported are unable to change the queue_depth of ata devices via sysfs Signed-off-by: Dan Williams <dan.j.williams@intel.com> Acked-by: Jeff Garzik <jgarzik@redhat.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

* | | libata: make ata_sff_data_xfer_noirq() work with 32-bit PIOBartlomiej Zolnierkiewicz2011-10-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Always use ata_sff_data_xfer32() in ata_sff_data_xfer_noirq() so the latter can be also used for host controllers supporting 32-bit PIO operations. It is a completely safe thing to do because if 32-bit PIO is not supported or enabled ata_sff_data_xfer32() will fallback to a standard method.

There shouldn't be any problems with it as corresponding IDE's host driver (aec62xx) has been supporting PCI Power Management since Oct 10 2008 (commit feb22b7f "ide: add proper PCI PM support (v2)") and IDE PM since Jun 14 2003 (patch v2.5.73 "ide: Power Management").
