This set starts with a few preparation commits to the NVMe host core layer. It continues with NVMeoF/RDMA host implementation + few preparation commits to the NVMe target core layer. The patchset ends with NVMeoF/RDMA target implementation. Configuration: Host: - nvme connect --pi_enable --transport=rdma --traddr=10.0.1.1 --nqn=test-nvme Target: - echo 1 > /config/nvmet/subsystems/${NAME}/attr_pi_enable - echo 1 > /config/nvmet/ports/${PORT_NUM}/param_pi_enable The code was tested using Mellanox's ConnectX-4/ConnectX-5 HCAs. This series applies on top of nvme_5.5 branch cleanly. Changes from v2: - Convert the virtual start sector (which passed to bip_set_seed function) to be in integrity interval units (Patch 14/15) - Clarify some commit messages Changes from v1: - Added Reviewed-by signatures - Added namespace features flag (Patch 01/15) - Remove nvme_ns_has_pi function (Patch 01/15) - Added has_pi field to struct nvme_request (Patch 01/15) - Subject change for patch 02/15 - Fix comment for PCI metadata (Patch 03/15) - Rebase over "nvme: Avoid preallocating big SGL for data" patchset - Introduce NVME_INLINE_PROT_SG_CNT flag (Patch 05/15) - Introduce nvme_rdma_sgl structure (Patch 06/15) - Remove first_sgl pointer from struct nvme_rdma_request (Patch 06/15) - Split nvme-rdma patches (Patches 06/15, 07/15) - Rename is_protected to use_pi (Patch 07/15) - Refactor nvme_rdma_get_max_fr_pages function (Patch 07/15) - Added ifdef CONFIG_BLK_DEV_INTEGRITY (Patches 07/15, 09/15, 13/15, 14/15, 15/15) - Added port configfs pi_enable (Patch 14/15) Israel Rukshin (12): nvme: Introduce namespace features flag nvme-fabrics: Allow user enabling metadata/T10-PI support nvme: Introduce NVME_INLINE_PROT_SG_CNT nvme-rdma: Introduce nvme_rdma_sgl structure nvmet: Prepare metadata request nvmet: Add metadata characteristics for a namespace nvmet: Rename nvmet_rw_len to nvmet_rw_data_len nvmet: Rename nvmet_check_data_len to nvmet_check_transfer_len nvme: Add Metadata Capabilities enumerations nvmet: Add metadata/T10-PI support nvmet: Add metadata support for block devices nvmet-rdma: Add metadata/T10-PI support Max Gurtovoy (3): nvme: Enforce extended LBA format for fabrics metadata nvme: Introduce max_integrity_segments ctrl attribute nvme-rdma: Add metadata/T10-PI support drivers/nvme/host/core.c | 75 +++++--- drivers/nvme/host/fabrics.c | 11 ++ drivers/nvme/host/fabrics.h | 3 + drivers/nvme/host/nvme.h | 9 +- drivers/nvme/host/pci.c | 7 + drivers/nvme/host/rdma.c | 368 +++++++++++++++++++++++++++++++++----- drivers/nvme/target/admin-cmd.c | 37 ++-- drivers/nvme/target/configfs.c | 61 +++++++ drivers/nvme/target/core.c | 54 ++++-- drivers/nvme/target/discovery.c | 8 +- drivers/nvme/target/fabrics-cmd.c | 19 +- drivers/nvme/target/io-cmd-bdev.c | 115 +++++++++++- drivers/nvme/target/io-cmd-file.c | 8 +- drivers/nvme/target/nvmet.h | 40 ++++- drivers/nvme/target/rdma.c | 235 ++++++++++++++++++++++-- include/linux/nvme.h | 2 + 16 files changed, 925 insertions(+), 127 deletions(-) -- 1.8.3.1 _______________________________________________ linux-nvme mailing list linux-nvme@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-nvme
