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 drivers/scsi/hisi_sas/hisi_sas.h | 48 +++-- drivers/scsi/hisi_sas/hisi_sas_main.c | 237 +++++++++++++++++++++---- drivers/scsi/hisi_sas/hisi_sas_v1_hw.c | 2 + drivers/scsi/hisi_sas/hisi_sas_v2_hw.c | 3 + drivers/scsi/hisi_sas/hisi_sas_v3_hw.c | 157 +++++++++++++--- 5 files changed, 377 insertions(+), 70 deletions(-) -- 2.17.1
