A detailed description of the new formats can be found in the NVMe's NVM Command Set Specification, section 5.2, available at: https://nvmexpress.org/wp-content/uploads/NVM-Command-Set-Specification-1.0b-2021.12.18-Ratified.pdf This series implements one possible new format: the CRC64 guard with 48-bit reference tags. This does not add support for the variable "storage tag" field, or any potential hardware acceleration. Changes since RFC v1: - Generated the reflected CRC table and cacluated CRC accordingly instead of reflecting the input/output (Eric Biggers, patch 3) - Fixed Kconfig.debug dependency for CRC tests (patch 4) - Fixed endian conversion sparse error (patch 7). - Added support for PRACT (Klaus Jensen, patch 7) Keith Busch (7): block: support pi with extended metadata nvme: allow integrity on extended metadata formats lib: add rocksoft model crc64 lib: add crc64 tests asm-generic: introduce be48 unaligned accessors block: add pi for nvme enhanced integrity nvme: add support for enhanced metadata block/Kconfig | 1 + block/bio-integrity.c | 1 + block/t10-pi.c | 198 +++++++++++++++++++++++++++++++- drivers/nvme/host/core.c | 167 ++++++++++++++++++++++----- drivers/nvme/host/nvme.h | 4 +- include/asm-generic/unaligned.h | 26 +++++ include/linux/blk-integrity.h | 1 + include/linux/crc64.h | 2 + include/linux/nvme.h | 53 ++++++++- include/linux/t10-pi.h | 20 ++++ lib/Kconfig.debug | 4 + lib/Makefile | 1 + lib/crc64.c | 26 +++++ lib/gen_crc64table.c | 51 ++++++-- lib/test_crc64.c | 68 +++++++++++ 15 files changed, 576 insertions(+), 47 deletions(-) create mode 100644 lib/test_crc64.c -- 2.25.4
