It is a raw device for allowing hardware DMA i.e. data copies in hardware. Performing the copies in hardware can provide performance improvements for applications where the average copy size is reasonably large, e.g. 1k packets. For smaller packets, e.g. 64-256 bytes, offloading the copy may reduce performance due to the overhead of using hardware. V5: * updated doxygen comment for internal rawdev pmd API V4: * changed memory management to use contiguous memzones instead of malloc memory * added missing device ids for BDX platforms * other misc cleanup following review (see individual patches logs) V3: * removed DPDK-specific structure for the descriptor format and reused the structure in the imported file rte_ioat_spec.h V2: * moved tests to rawdev selftest function * some checkpatch and other small cleanups * added extra documentation details on supported hardware * aligned the changes to dpdk-devbind with the changes in the NTB set for consistency Bruce Richardson (9): rawdev: allow devices to skip extra memory allocation raw/ioat: add initial support for ioat rawdev driver usertools/dpdk-devbind.py: add support for IOAT devices raw/ioat: add register definition file raw/ioat: create device on probe and destroy on release raw/ioat: add device info function raw/ioat: add configure, start and stop functions raw/ioat: add statistics functions raw/ioat: add local API to perform copies MAINTAINERS | 5 + app/test/test_rawdev.c | 20 ++ config/common_armv8a_linux | 1 + config/common_base | 5 + config/defconfig_arm-armv7a-linuxapp-gcc | 1 + config/defconfig_ppc_64-power8-linuxapp-gcc | 1 + doc/guides/rawdevs/index.rst | 1 + doc/guides/rawdevs/ioat_rawdev.rst | 265 +++++++++++++++ doc/guides/rel_notes/release_19_08.rst | 11 + drivers/raw/Makefile | 1 + drivers/raw/ioat/Makefile | 31 ++ drivers/raw/ioat/ioat_rawdev.c | 356 ++++++++++++++++++++ drivers/raw/ioat/ioat_rawdev_test.c | 235 +++++++++++++ drivers/raw/ioat/meson.build | 10 + drivers/raw/ioat/rte_ioat_rawdev.h | 234 +++++++++++++ drivers/raw/ioat/rte_ioat_spec.h | 301 +++++++++++++++++ drivers/raw/ioat/rte_pmd_ioat_version.map | 4 + drivers/raw/meson.build | 4 +- lib/librte_rawdev/rte_rawdev.c | 11 +- lib/librte_rawdev/rte_rawdev_pmd.h | 4 +- mk/rte.app.mk | 1 + usertools/dpdk-devbind.py | 10 + 22 files changed, 1505 insertions(+), 7 deletions(-) create mode 100644 doc/guides/rawdevs/ioat_rawdev.rst create mode 100644 drivers/raw/ioat/Makefile create mode 100644 drivers/raw/ioat/ioat_rawdev.c create mode 100644 drivers/raw/ioat/ioat_rawdev_test.c create mode 100644 drivers/raw/ioat/meson.build create mode 100644 drivers/raw/ioat/rte_ioat_rawdev.h create mode 100644 drivers/raw/ioat/rte_ioat_spec.h create mode 100644 drivers/raw/ioat/rte_pmd_ioat_version.map -- 2.21.0
