- simplify the driver - there are a lot of quirky racy conditions not handled - causes more aborts/resets when the number of commands to be aborted is large, such as in multi-path fail-overs. - has been turned off in our internal driver since 8/31/2015 Reviewed-by:

- Block I/O requests with 0 length transfers which go down the ioaccel path. This causes lockup issues down in the basecode. - These issues have been fixed, but there are customers who are experiencing the issues when running older firmware. Reviewed-by:

create new worker thread to monitor controller events - both the rescan and event monitor workers can cause a rescan to occur however for multipath we have found that we need to respond faster than the normal scheduled rescan interval for path fail-overs. - getting controller events only involves reading a register, but the rescan worker can obtain an updated LUN list when there is a PTRAID device present. - move common code to a separate function. advantages: - detect controller events more frequently. - leave rescan thread interval at 30 seconds.

The command thread checks the ctrl health periodically before sending updates to the controller. The function that it uses is aac_check_health which does more than get the health status. Signed-off-by:

Now the driver issues a soft reset and waits for the controller to be up and running by periodically checking on the status of the controller health registers. Also prevents ARC adapters from issuing soft reset if IOP resets failed. Signed-off-by:

The default queue depth for non NATIVE RAW disks is calculated from the number of fibs and number of disks or a max of 256. This causes poor disk IO performance. The fix is to set default qd based on the type of disks (SATA -32 and SAS -64) Signed-off-by:

The qd for ARC Native disks is calculated by dividing the max IO 1024 by the number of disks or 256 which ever is lower. This causes poor disk IO performance. The fix is set the qd based on the type of disk (SAS - 64 and SATA - 32). Signed-off-by:

The driver changed the DMA consistent map after consistent memory was allocated, this invalidated the IOMMU identity mapping. The fix was to make sure that we set the DMA consistent mask setting once depending on the controller card. Signed-off-by:

Commit abb2ea7d ("compiler, clang: suppress warning for unused static inline functions") just caused more warnings due to re-defining the 'inline' macro. So undef it before re-defining it, and also add the 'notrace' attribute like the gcc version that this is overriding does. Maybe this makes clang happier. Signed-off-by:
