This patchset introduces support to the driver for DIF/DIX (or PI - protection information). We will only support PI in v3 hw at the moment, even though previous hw versions also support it. The series is broken down as follows: - Tidy sg table size config - Some tidy-up to accept PI support - Add components for PI support for main and v3 driver Difference v1->v2: - drop scsi_prot_op_normal() Xiang Chen (3): scsi: hisi_sas: Relocate some code to reduce complexity scsi: hisi_sas: Make sg_tablesize consistent value scsi: hisi_sas: Add support for DIF/DIX feature for v3 hw drivers/scsi/hisi_sas/hisi_sas.h | 18 +++ drivers/scsi/hisi_sas/hisi_sas_main.c | 242 ++++++++++++++++++++++++--------- drivers/scsi/hisi_sas/hisi_sas_v1_hw.c | 2 +- drivers/scsi/hisi_sas/hisi_sas_v2_hw.c | 2 +- drivers/scsi/hisi_sas/hisi_sas_v3_hw.c | 192 +++++++++++++++++++++++++- 5 files changed, 380 insertions(+), 76 deletions(-) -- 1.9.1
