This patchset introduces the following: - DIX support for v3 hw
- Optimisation based on mapping CPUs to queues, much the same as other SCSI drivers do today, without exposing > 1 queue to upper layer.
It is disabled by default and marked as experimental, due to ongoing discussion here: https://marc.info/?l=linux-scsi&m=154876335707751&w=2
In addition, hopefully we can eventually expose > 1 queue to upper layer and remove the reply_map, if performance issue discussed here has a positive outcome: https://marc.info/?l=linux-scsi&m=154874776701343&w=2
- And some other minor tidying and a driver debugfs feature
This series is based on Martin's 5.1 queue + "scsi: hisi_sas: Set protection parameters prior to adding SCSI host"
John Garry (2): scsi: hisi_sas: Issue internal abort on all relevant queues scsi: hisi_sas: Do some more tidy-up
Luo Jiaxing (1): scsi: hisi_sas: Add manual trigger for debugfs dump
Xiang Chen (3): scsi: hisi_sas: Add support for DIX feature for v3 hw scsi: hisi_sas: change queue depth from 512 to 4096 scsi: hisi_sas: Use pci_irq_get_affinity() for v3 hw as experimental
