Introduce a new compress PMD for hardware accelerators based on UADK [1]. UADK is a framework for user applications to access hardware accelerators. UADK relies on IOMMU SVA (Shared Virtual Address) feature, which share the same page table between IOMMU and MMU. Thereby user application can directly use virtual address for device dma, which enhances the performance as well as easy usability.
Besides, crypto PMD is under drivers/crypto/uadk/ [1] https://github.com/Linaro/uadk Test: sudo dpdk-test --vdev=compress_uadk RTE>>compressdev_autotest RTE>>quit dd if=/dev/random of=data bs=1M count=1; sudo dpdk-test-compress-perf -l 1,2 --vdev compress_uadk \ -- --driver-name compress_uadk --input-file data Zhangfei Gao (3): compress/uadk: Introduce UADK compression driver compress/uadk: support basic operations compress/uadk: support burst enqueue/dequeue MAINTAINERS | 6 + doc/guides/compressdevs/features/uadk.ini | 11 + doc/guides/compressdevs/index.rst | 1 + doc/guides/compressdevs/uadk.rst | 98 ++++ doc/guides/rel_notes/release_24_07.rst | 5 + drivers/compress/meson.build | 1 + drivers/compress/uadk/meson.build | 30 ++ drivers/compress/uadk/uadk_compress_pmd.c | 476 ++++++++++++++++++ .../compress/uadk/uadk_compress_pmd_private.h | 36 ++ 9 files changed, 664 insertions(+) create mode 100644 doc/guides/compressdevs/features/uadk.ini create mode 100644 doc/guides/compressdevs/uadk.rst create mode 100644 drivers/compress/uadk/meson.build create mode 100644 drivers/compress/uadk/uadk_compress_pmd.c create mode 100644 drivers/compress/uadk/uadk_compress_pmd_private.h -- 2.25.1
