In v3 PTPL is supported, which is passed as a parameter. v1->v2: - Add sg_persist --report-capabilities for SCSI protocol and enable oncs and rescap for NVMe protocol. - Add persistent reservation capabilities constants and helper functions for SCSI and NVMe protocol. - Add comments for necessary APIs. v1: - Add seven APIs about persistent reservation command for block layer. These APIs including reading keys, reading reservations, registering, reserving, releasing, clearing and preempting. - Add the necessary pr-related operation APIs for both the SCSI protocol and NVMe protocol at the device layer. - Add scsi driver at the driver layer to verify the functions Changqi Lu (10): block: add persistent reservation in/out api block/raw: add persistent reservation in/out driver scsi/constant: add persistent reservation in/out protocol constants scsi/util: add helper functions for persistent reservation types conversion hw/scsi: add persistent reservation in/out api for scsi device block/nvme: add reservation command protocol constants hw/nvme: add helper functions for converting reservation types hw/nvme: enable ONCS and rescap function hw/nvme: add reservation protocal command block/iscsi: add persistent reservation in/out driver block/block-backend.c | 403 +++++++++++++++++++++++++++ block/io.c | 163 +++++++++++ block/iscsi.c | 443 ++++++++++++++++++++++++++++++ block/raw-format.c | 56 ++++ hw/nvme/ctrl.c | 326 +++++++++++++++++++++- hw/nvme/ns.c | 5 + hw/nvme/nvme.h | 84 ++++++ hw/scsi/scsi-disk.c | 352 ++++++++++++++++++++++++ include/block/block-common.h | 40 +++ include/block/block-io.h | 20 ++ include/block/block_int-common.h | 84 ++++++ include/block/nvme.h | 98 +++++++ include/scsi/constants.h | 52 ++++ include/scsi/utils.h | 8 + include/sysemu/block-backend-io.h | 24 ++ scsi/utils.c | 81 ++++++ 16 files changed, 2237 insertions(+), 2 deletions(-)
