* [SCSI] mvsas: add support for Task collector mode and fixed relative bugsXiangliang Yu2011-05-011-0/+1
| | | | | | | | | | | | | 1. Add support for Task collector mode. 2. Fixed relative collector mode bug: - I/O failed when disks is on two ports - system hang when hotplug disk - system hang when unplug disk during run IO 3. Unlock ap->lock within .lldd_execute_task for direct mode to improve performance Signed-off-by: Xiangliang Yu <yuxiangl@marvell.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
* [SCSI] mvsas: fix hot plug handling and IO issuesSrinivas2010-04-111-2/+23
| | | | | | | | | | | | | | | | | | | | | This patch adds a bunch of fixes 1. Reduce sg table size to 64 (SG_MX) instead of default SG_ALL 2. clear task lists on phy down events 3. release all tasks on port deformation 4. release current task for device gone notification 5. Add sata abort handing 6. Add 10ms delay to each port reset (currently done serially and with interrupts disabled) [jejb: whitespace fixes and clean ups plus added description added dummy 94xx_clear_srs_irq function just to prevent the mismatch in the mvs_dispatch structure killing 94xx cards] Signed-off-by: Srinivas <satyasrinivasp@hcl.in> Cc: Andy Yan <ayan@marvell.com> Cc: qswang@marvell.com Cc: jfeng@marvell.com Signed-off-by: James Bottomley <James.Bottomley@suse.de>
