It\nis a raw device for allowing hardware DMA i.e. data copies in hardware.\n\nPerforming the copies in hardware can provide performance improvements\nfor applications where the average copy size is reasonably large, e.g.\n1k packets. For smaller packets, e.g. 64-256 bytes, offloading the copy\nmay reduce performance due to the overhead of using hardware.\n\nV2:\n* moved tests to rawdev selftest function\n* some checkpatch and other small cleanups\n* added extra documentation details on supported hardware\n* aligned the changes to dpdk-devbind with the changes in the NTB set\n for consistency\n\nBruce Richardson (8):\n raw/ioat: add initial support for ioat rawdev driver\n usertools/dpdk-devbind.py: add support for IOAT devices\n raw/ioat: add register definition file\n raw/ioat: create device on probe and destroy on release\n raw/ioat: add device info function\n raw/ioat: add configure, start and stop functions\n raw/ioat: add statistics functions\n raw/ioat: add local API to perform copies\n\n MAINTAINERS | 6 +-\n app/test/test_rawdev.c | 19 ++\n config/common_armv8a_linux | 1 +\n config/common_base | 5 +\n config/defconfig_arm-armv7a-linuxapp-gcc | 1 +\n config/defconfig_ppc_64-power8-linuxapp-gcc | 1 +\n doc/guides/rawdevs/index.rst | 1 +\n doc/guides/rawdevs/ioat_rawdev.rst | 265 +++++++++++++++++\n doc/guides/rel_notes/release_19_08.rst | 11 +\n drivers/raw/Makefile | 1 +\n drivers/raw/ioat/Makefile | 31 ++\n drivers/raw/ioat/ioat_rawdev.c | 313 ++++++++++++++++++++\n drivers/raw/ioat/ioat_rawdev_test.c | 235 +++++++++++++++\n drivers/raw/ioat/meson.build | 10 +\n drivers/raw/ioat/rte_ioat_rawdev.h | 242 +++++++++++++++\n drivers/raw/ioat/rte_ioat_spec.h | 301 +++++++++++++++++++\n drivers/raw/ioat/rte_pmd_ioat_version.map | 4 +\n drivers/raw/meson.build | 4 +-\n mk/rte.app.mk | 1 +\n usertools/dpdk-devbind.py | 10 +\n 20 files changed, 1460 insertions(+), 2 deletions(-)\n create mode 100644 doc/guides/rawdevs/ioat_rawdev.rst\n create mode 100644 drivers/raw/ioat/Makefile\n create mode 100644 drivers/raw/ioat/ioat_rawdev.c\n create mode 100644 drivers/raw/ioat/ioat_rawdev_test.c\n create mode 100644 drivers/raw/ioat/meson.build\n create mode 100644 drivers/raw/ioat/rte_ioat_rawdev.h\n create mode 100644 drivers/raw/ioat/rte_ioat_spec.h\n create mode 100644 drivers/raw/ioat/rte_pmd_ioat_version.map" }
