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. *** SUBJECT HERE ***\n\n[1] https://01.org/blogs/2019/introducing-intel-data-streaming-accelerator\n\n---\nV2:\n * Included documentation additions in the set\n * Split off the rawdev unit test changes to a separate patchset for easier\n review\n * General code improvements and cleanups\n\n\nBruce Richardson (14):\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: include example configuration script\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 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 doc/guides/rawdevs/ioat.rst | 131 +++--\n drivers/raw/ioat/dpdk_idxd_cfg.py | 79 +++\n drivers/raw/ioat/idxd_pci.c | 344 +++++++++++++\n drivers/raw/ioat/idxd_vdev.c | 234 +++++++++\n drivers/raw/ioat/ioat_common.c | 237 +++++++++\n drivers/raw/ioat/ioat_private.h | 80 +++\n drivers/raw/ioat/ioat_rawdev.c | 95 +---\n drivers/raw/ioat/ioat_rawdev_test.c | 1 +\n .../raw/ioat/{rte_ioat_spec.h => ioat_spec.h} | 90 +++-\n drivers/raw/ioat/meson.build | 15 +-\n drivers/raw/ioat/rte_ioat_rawdev.h | 169 ++-----\n drivers/raw/ioat/rte_ioat_rawdev_fns.h | 474 ++++++++++++++++++\n usertools/dpdk-devbind.py | 4 +-\n 13 files changed, 1646 insertions(+), 307 deletions(-)\n create mode 100755 drivers/raw/ioat/dpdk_idxd_cfg.py\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} (74%)\n create mode 100644 drivers/raw/ioat/rte_ioat_rawdev_fns.h" }
