Most rework and enhancements\nare largely self-explanatory from the individual patches.\n\nThe new hardware support is for the Intel(R) DSA accelerator which will be\npresent in future Intel processors. A description of this new hardware is\ncovered in [1]. Functions specific to the new hardware use the \"idxd\"\nprefix, for consistency with the kernel driver.\n\nThis set is being sent for initial review and evaluation. Any documentation\nchanges needed and a few additional updates to the code are planned for V2\nof this patchset in the 20.11 timeframe.\n\n[1] https://01.org/blogs/2019/introducing-intel-data-streaming-accelerator\n\nBruce Richardson (16):\n raw/ioat: support multiple devices being tested\n app/test: change rawdev autotest to run selftest on all devs\n app/test: remove ioat-specific autotest\n raw/ioat: split header for readability\n raw/ioat: make the HW register spec private\n raw/ioat: add skeleton for vfio/uio based DSA device\n raw/ioat: create rawdev instances on idxd PCI probe\n raw/ioat: add datapath data structures for idxd devices\n raw/ioat: add configure function for idxd devices\n raw/ioat: add start and stop functions for idxd devices\n raw/ioat: add data path support for idxd devices\n raw/ioat: add info function for idxd devices\n raw/ioat: create separate statistics structure\n raw/ioat: move xstats functions to common file\n raw/ioat: add xstats tracking for idxd devices\n raw/ioat: clean up use of common test function\n\nCheng Jiang (1):\n raw/ioat: add a flag to control copying handle parameters\n\nKevin Laatz (3):\n usertools/dpdk-devbind.py: add support for DSA HW\n raw/ioat: add vdev probe for DSA/idxd devices\n raw/ioat: create rawdev instances for idxd vdevs\n\n app/test/test_rawdev.c | 37 +-\n drivers/raw/ioat/idxd_pci.c | 345 +++++++++++++\n drivers/raw/ioat/idxd_vdev.c | 344 +++++++++++++\n drivers/raw/ioat/ioat_common.c | 250 +++++++++\n drivers/raw/ioat/ioat_private.h | 82 +++\n drivers/raw/ioat/ioat_rawdev.c | 94 +---\n drivers/raw/ioat/ioat_rawdev_test.c | 18 +-\n .../raw/ioat/{rte_ioat_spec.h => ioat_spec.h} | 78 ++-\n drivers/raw/ioat/meson.build | 20 +-\n drivers/raw/ioat/rte_ioat_rawdev.h | 169 ++-----\n drivers/raw/ioat/rte_ioat_rawdev_fns.h | 475 ++++++++++++++++++\n usertools/dpdk-devbind.py | 4 +-\n 12 files changed, 1637 insertions(+), 279 deletions(-)\n create mode 100644 drivers/raw/ioat/idxd_pci.c\n create mode 100644 drivers/raw/ioat/idxd_vdev.c\n create mode 100644 drivers/raw/ioat/ioat_common.c\n create mode 100644 drivers/raw/ioat/ioat_private.h\n rename drivers/raw/ioat/{rte_ioat_spec.h => ioat_spec.h} (78%)\n create mode 100644 drivers/raw/ioat/rte_ioat_rawdev_fns.h" }
