2006-08-09[PATCH] libata: clear sdev->locked on door lock failureTejun Heo1-0/+13
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 <uchang@tw.ibm.com>.

2006-08-09[PATCH] ahci: remove IRQ mask clearing from init_controller()Tejun Heo1-2/+1

2006-08-09[PATCH] libata: Add support for SATA attachment to SAS adaptersBrian King3-1/+151
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 <brking@us.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-07-29[PATCH] libata: improve driver initialization and deinitializationTejun Heo1-51/+151
Implement ahci_[de]init_port() and use it during initialization and de-initialization. ahci_[de]init_port() are supersets of what used to be done during driver [de-]initialization. This patch makes the following behavior changes. * Per-port IRQ mask is cleared on driver load as done in other drivers. The mask will be configured properly during probe. * During init_one(), HOST_IRQ_STAT is cleared after masking port IRQs such that there is no race window. * CMD_SPIN_UP is cleared during init_one() instead of being set. It is set in port_start(). This is more consistent with overall structure of initialization. Note that CMD_SPIN_UP simply controls PHY activation. * Slumber and staggered spin-up are handled properly. * All init/deinit operations are done in step-by-step manner as described in the spec instead of issued as single merged command.

2006-07-29[PATCH] ahci: simplify ahci_start_engine()Tejun Heo1-19/+2
Simplify ahci_start_engine() by killing prerequisite condition checks. Rationales are.. * No user checks error return from ahci_start_engine() * Code flow guarantees the prerequisite conditions unless the controller is malfunctioning. In such cases, the driver had chances to learn about the problem _before_ calling this function. * Closely related to the above two, driver calls into this function even when prerequisites fail hoping for the best. Basically, ahci_start_engine() should only do the operation itself. It isn't the right place to check for prerequisites.

2006-07-26[PATCH] fix compile regression for a few scsi driversChristoph Hellwig2-12/+6
This fixes three drivers to compile again after my patch that removes the data_cmnd member from struct scsi_cmnd. The fas216 change is trivial, it should have been using ->cmnd all the time. NCR53C9 (which seem to be mostly duplicate driver with esp.c!) is doing something odd, it should only have looked at ->cmnd before not the saved copy that is kept for the error handlers sake. Note that it really should deal with the sync setting themselves but use the generic domain validation code that get this right - but that's for later let's push this simple compile fix for now. And sorry for the late fix for this, I have been busy with OLS and associated activities last week. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-07-19[PATCH] libata: improve EH action and EHI flag handlingTejun Heo1-5/+28
Update ata_eh_about_to_do() and ata_eh_done() to improve EH action and EHI flag handling. * There are two types of EHI flags - one which expires on successful EH and the other which expires on a successful reset. Make this distinction clear. * Unlike other EH actions, reset actions are represented by two EH action masks and a EHI modifier. Implement correct about_to_do/done semantics for resets. That is, prior to reset, related EH info is sucked in from ehi and cleared, and after reset is complete, related EH info in ehc is cleared. These changes improve consistency and remove unnecessary EH actions caused by stale EH action masks and EHI flags.

2006-07-19[PATCH] libata: fix eh_skip_recovery conditionTejun Heo1-3/+4
* (ata_dev_absent() || ata_dev_ready()) test doesn't indicate SUSPENDED state properly. Fix it. * Link resuming resets shouldn't be skipped. Don't skip recovery on EHI_RESUME_LINK. This doesn't matter for host ports as EHI_RESUME always coincides with EHI_HOTPLUGGED which makes attached disabled devices vacant. However, PMP reset causes non-hotplug link-resuming resets which shouldn't be skipped. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-07-19[PATCH] libata: fix autopsy ehc->i.action and ehc->i.dev handlingTejun Heo1-17/+12
Commit 0662c58b3265f52f708a6d59476bc7862b01f9c0 updated ata_eh_autopsy() to OR determined action to ehc->i.action to preserve action mask set directly into ehc->i.action by nested functions. This broke action mask clearing on SENSE_VALID case causing revalidation and EH complete message on successful ATAPI CC. This patch removes two local variables - action and failed_dev - which cache ehc->i.action and ehc->i.dev respectively, and make the function directly modify ehc->i.* fields to remove aliasing issues.

2006-07-16[libata] ata_piix: Consolidate PCS register writingJeff Garzik1-25/+28
Prior to this patch, the driver would do this for each port: read 8-bit PCS write 8-bit PCS read 8-bit PCS write 8-bit PCS In the field, flaky behavior has been observed related to this register. In particular, these overzealous register writes can cause misdetection problems. Update to do the following once (not once per port) at boot: read 16-bit PCS if needs changing, write 16-bit PCS And thereafter, we only perform a 'read 16-bit PCS' per port. This should eliminate all PCS writes in many cases, and be more friendly in the cases where we do need to enable ports. Signed-off-by: Jeff Garzik <jeff@garzik.org>
