[PATCH 0/5] hisi_sas: Interrupt aggregation support

From: John Garry
Date: Fri Nov 09 2018 - 09:05:07 EST


This patchset adds 2 forms of interrupt aggregation support to the
driver:
- Interrupt converge: Interrupts from all completion queues can be
reported through completion queue #0 interrupt only.
- Interrupt coalesce: Ability to set timeout period at which we report
completions on that queue (as an interrupt).
The HW report completion interrupt as either
happens:
- configurable threshold of completions occur
- a timeout, so we don't pend indefinitely until
the threshold is reached

There is also 2 minor patches to fix some register setting and also
rearrange some code for proper condition checking.

Xiang Chen (5):
scsi: hisi_sas: Create separate host attributes per HBA
scsi: hisi_sas: Add support for interrupt converge for v3 hw
scsi: hisi_sas: Add support for interrupt coalescing for v3 hw
scsi: hisi_sas: Relocate some codes to avoid an unused check
scsi: hisi_sas: change the time of SAS SSP connection
