scsi: aacraid: change event_wait to a completion

2018-12-13T01:35:33Z

The event_wait semaphore has completion semantics, so we can change it over to the completion interface for clarity without changing the behavior. Signed-off-by: Arnd Bergmann Reviewed-by: Johannes Thumshirn Reviewed-by: Dave Carroll Signed-off-by: Martin K. Petersen

scsi: aacraid: Added support for response path

This patch enables the driver to actually process the I/O, or srb replies from adapter. In addition to any HBA1000 or SmartIOC2000 adapter events. Signed-off-by: Raghava Aditya Renukunta Signed-off-by: Dave Carroll Reviewed-by: Johannes Thumshirn Signed-off-by: Martin K. Petersen

aacraid: Remove code to needlessly complete fib

2016-04-29T23:08:24Z

Currently driver completes double completed or spurious interrupted fibs. This is not necessary and causes the SCSI mid layer to issue aborts and resets, since completing a fib prematurely might trigger a race condition resulting in the driver not calling the scsi_done callback. Fixed by removing the call to fib complete. Signed-off-by: Raghava Aditya Renukunta Reviewed-by: Johannes Thumshirn Signed-off-by: Martin K. Petersen

aacraid: SCSI blk tag support

2016-02-24T02:27:02Z

The method to allocate and free FIB's in the present code utilizes spinlocks. Multiple IO's have to wait on the spinlock to acquire or free fibs creating a performance bottleneck. An alternative solution would be to use block layer tags to keep track of the fibs allocated and freed. To this end aac_fib_alloc_tag was created to utilize the blk layer tags to plug into the Fib pool.These functions are used exclusively in the IO path. 8 fibs are reserved for the use of AIF management software and utilize the previous spinlock based implementations.
