scsi: aacraid: Fix controller initialization failure

2017-11-02T08:54:48Z

commit 45348de2c8a7a1e64c5be27b22c9786b4152dd41 upstream. This is a fix to an issue where the driver sends its periodic WELLNESS command to the controller after the driver shut it down.This causes the controller to crash. The window where this can happen is small, but it can be hit at around 4 hours of constant resets.

scsi: aacraid: Change wait time for fib completion

2017-06-13T00:47:59Z

Change the completion wait time for the fibs in the reset and abort callback from 2 minutes to 15 seconds. 2 minutes is too long for waiting for completion. Signed-off-by: Raghava Aditya Renukunta Reviewed-by: David Carroll Signed-off-by: Martin K. Petersen

scsi: aacraid: Set correct Queue Depth for HBA1000 RAW disks

2017-06-13T00:47:59Z

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: Raghava Aditya Renukunta Reviewed-by: David Carroll Signed-off-by: Martin K. Petersen

scsi: aacraid: Added 32 and 64 queue depth for arc natives

2017-06-13T00:47:59Z

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: Raghava Aditya Renukunta Reviewed-by: David Carroll Signed-off-by: Martin K. Petersen

scsi: aacraid: Fix DMAR issues with iommu=pt

2017-06-13T00:47:59Z

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: Raghava Aditya Renukunta Reviewed-by: Dave Carroll Signed-off-by: Martin K.
