We are dropping DIX support for now, based on issues discussed in the following: https://marc.info/?l=linux-scsi&m=154357719329297&w=4 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: - Fix pre-existing sparse warnings - 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() v2->v3: - fix sparse warnings - drop DIX support John Garry (1): scsi: hisi_sas: Fix warnings detected by sparse 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 feature for v3 hw drivers/scsi/hisi_sas/hisi_sas.h | 20 ++- drivers/scsi/hisi_sas/hisi_sas_main.c | 248 +++++++++++++++++++++++---------- drivers/scsi/hisi_sas/hisi_sas_v1_hw.c | 17 +-- drivers/scsi/hisi_sas/hisi_sas_v2_hw.c | 68 +++++---- drivers/scsi/hisi_sas/hisi_sas_v3_hw.c | 227 +++++++++++++++++++++++++++--- 5 files changed, 448 insertions(+), 132 deletions(-)
