Subject: [PATCH 00/15 V3] nvme-rdma/nvmet-rdma: Add metadata/T10-PI support
Date: Mon, 6 Jan 2020 15:37:20 +0200 [thread overview]
Message-ID: <20200106133736.123038-1-maxg@mellanox.com> (raw)
Hello Sagi, Christoph, Keith, Martin and Co
This patchset adds metadata (T10-PI) support for NVMeoF/RDMA host side and
target side, using signature verbs API. 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)
