2014-03-15[SCSI] qla4xxx: Reduce rom-lock contention during reset recovery.Vikas Chaudhary1-21/+12
Issue: Driver holds rom-lock for too long during reset recovery. During adapter reset testing, it was found that the driver holds the rom-lock for too long, because of which other drivers fail to acquire the rom-lock, leading to reset failures. The primary cause is, in the bootstrap code, while holding the rom-lock, the driver checks if the peg is halted, causing a 2 second contention. Fix: When a reset recovery starts, the driver deduces the cause, and sets appropriate flags in watchdog & recover_adapter routines. This flag should be used to determine if bootstrap is invoked from probe or reset context, reducing the rom-lock footprint of the drivers.

chip reset Issue: Pending IO wait does not complete after triggering Graceful reset, causing ack timeout and call traces. Fix: 1. Reducing the IO command wait timeout before triggering reset, as logically also timeout should be less than reset timeout (10sec). 2.

Add controller-based data-at-rest encryption compatibility to ioaccel2 path (HP SSD Smart Path). Encryption feature requires driver to supply additional fields for encryption enable, tweak index, and data encryption key index in the ioaccel2 request structure. Encryption enable flag and data encryption key index come from raid_map data structure from raid offload command. During ioaccel2 submission, check device structure's raid map to see if encryption is enabled for the device. If so, call new function below. Add function set_encrypt_ioaccel2 to set encryption flag, data encryption key index, and calculate tweak value from request's logical block address.

2014-03-15[SCSI] hpsa: rescan devices on ioaccel2 errorScott Teel2-2/+11
Allow driver to schedule a rescan whenever a request fails on the ioaccel2 path. This eliminates the possibility of driver getting stuck in non-ioaccel mode. IOaccel mode (HP SSD Smart Path) is disabled by driver upon error detection. Driver relied on idea that request would be retried through normal path, and a subsequent error would occur on that path, and be processed by controller firmware. As part of that process, controller disables ioaccel mode and later reinstates it, signalling driver to change modes. In some error cases, the error will not duplicate on the standard path, so the driver could get stuck in non-ioaccel mode. To avoid that, we allow driver to request a rescan during the next run of the rescan thread. Signed-off-by: Scott Teel <[email protected]> Signed-off-by: Stephen M.
