This patchset introduces support to the driver for DIF/DIX. We are making DIX support as RFC for now, based on issues discussed in the following: https://marc.info/?l=linux-scsi&m=154357719329297&w=4 and https://marc.info/?l=linux-scsi&m=154406987703456&w=2 We will only support PI in v3 hw at the moment, even though previous hw versions also support it. Differences: v4->v5: - Drop already accepted patches - Fix comments according to Martin - use t10_pi_ref_tag() - stop using protection options in LLDD in favour of prot flags - allow user to set prot mask v3->v4: - re-add DIX support as RFC - do not commit please! - also DIX support is labelled experimental in the driver v2->v3: - fix sparse warnings - drop DIX support v1->v2: - drop scsi_prot_op_normal() Xiang Chen (2): scsi: hisi_sas: Add support for DIF feature for v2 hw scsi: hisi_sas: Add support for DIX feature for v3 hw as experimental drivers/scsi/hisi_sas/hisi_sas.h | 28 +++++ drivers/scsi/hisi_sas/hisi_sas_main.c | 97 ++++++++++++++-- drivers/scsi/hisi_sas/hisi_sas_v3_hw.c | 197 ++++++++++++++++++++++++++++++++- 3 files changed, 305 insertions(+), 17 deletions(-) -- 1.9.1
