The uring passthrough was introduced with 5.19 io_uring. To send nvme uring passthrough commands we require helpers to fetch NVMe char device (/dev/ngXnY) specific fields such as namespace id, lba size etc. How to run: ./test/io_uring_passthrough.t /dev/ng0n1 It requires argument to be NVMe device, if not the test will be skipped. The test covers write/read with verify for sqthread poll, vectored / nonvectored and fixed IO buffers, which can be extended in future. As of now iopoll is not supported for passthrough commands, there is a test for such case. Changes from v2 to v3 - Skip test if argument is not nvme device and remove prints, as suggested by Jens. - change nvme helper function name, as pointed by Jens. - Remove wrong comment about command size, as per Kanchan's review Ankit Kumar (5): configure: check for nvme uring command support io_uring.h: sync sqe entry with 5.20 io_uring nvme: add nvme opcodes, structures and helper functions test: add io_uring passthrough test test/io_uring_passthrough: add test case for poll IO configure | 20 ++ src/include/liburing/io_uring.h | 17 +- test/Makefile | 1 + test/io_uring_passthrough.c | 390 ++++++++++++++++++++++++++++++++ test/nvme.h | 168 ++++++++++++++ 5 files changed, 594 insertions(+), 2 deletions(-) create mode 100644 test/io_uring_passthrough.c create mode 100644 test/nvme.h -- 2.17.1
