[PATCH] libata: clear sdev->locked on door lock failure

2006-08-09T05:16:27+00:00

SCSI EH locks door if sdev->locked is set. Sometimes door lock command fails continuously (e.g. when medium is not present) and as libata uses EH to acquire sense data, this easily creates a loop where a failed lock door invokes EH and EH issues lock door on completion. This patch clears sdev->locked on door lock failure to break this loop. This problem has been spotted and diagnosed by Unicorn Chang . Signed-off-by: Tejun Heo Signed-off-by: Jeff Garzik

[PATCH] libata: Add support for SATA attachment to SAS adapters

2006-08-09T04:08:39+00:00

The following patch enhances libata to allow SAS device drivers to utilize libata to talk to SATA devices. It introduces some new APIs which allow libata to be used without allocating a virtual scsi host. New APIs: ata_sas_port_alloc - Allocate an ata_port ata_sas_port_init - Initialize an ata_port (probe device, etc) ata_sas_port_destroy - Free an ata_port allocated by ata_sas_port_alloc ata_sas_slave_configure - configure scsi device ata_sas_queuecmd - queue a scsi command, similar to ata_scsi_queuecomand These new APIs can be used either directly by a SAS LLDD or could be used by the SAS transport class. Possible usage for a SAS LLDD would be: scsi_scan_host target_alloc ata_sas_port_alloc slave_alloc ata_sas_port_init slave_configure ata_sas_slave_configure Commands received by the LLDD for SATA devices would call ata_sas_queuecmd. Device teardown would occur with: slave_destroy port_disable target_destroy ata_sas_port_destroy Signed-off-by: Brian King Signed-off-by: Jeff Garzik

[PATCH] libata: reimplement per-dev PM

2006-07-06T02:16:28+00:00

Reimplement per-dev PM. The original implementation directly put the device into suspended mode and didn't synchronize w/ EH operations including hotplug. This patch reimplements ata_scsi_device_suspend() and ata_scsi_device_resume() such that they request EH to perform the respective operations. Both functions synchronize with hotplug such that it doesn't operate on detached devices. Suspend waits for completion but resume just issues request and returns. This allows parallel wake up of devices and thus speeds up system resume. Due to sdev detach synchronization, it's not feasible to separate out EH requesting from sdev handling; thus, ata_device_suspend/resume() are removed and everything is implemented in the respective libata-scsi functions.

[PATCH] libata: implement ATA_EHI_RESUME_LINK

2006-07-06T02:16:27+00:00

Implement ATA_EHI_RESUME_LINK, which indicates that the link needs to be resumed. This used to be implied by ATA_EHI_HOTPLUGGED. However, hotplug isn't the only event which requires link resume and separating this out allows other places to request link resume. This differentiation also allows better debounce timing selection. This patch converts user scan to use ATA_EHI_RESUME_LINK. Signed-off-by: Tejun Heo Signed-off-by: Jeff Garzik

[PATCH] libata: add ap->pflags and move core dynamic flags to it

2006-07-06T01:51:42+00:00

ap->flags is way too clamped. Separate out core dynamic flags to ap->pflags. ATA_FLAG_DISABLED is a dynamic flag but left alone as it's referenced by a lot of LLDs and it's gonna be removed once all LLDs are converted to new EH. Signed-off-by: Tejun Heo Signed-off-by: Jeff Garzik
