But since there is no FIFO here, only support file which is\nno more than 4M. And will add FIFO in the future.\n\nv2:\n* Replaced ! with NULL check for pointers.\n* Added ntb_ops valid check before use it.\n* Replaced RTE_MEMZONE_1GB with RTE_MEMZONE_IOVA_CONTIG in case users do\n not use 1G hugepage.\n* Added a timeout for dev_stop handshake in case that the peer stopped\n abnormally such as crashed while debugging.\n* Updated docs especailly about how to setup BIOS for skylake.\n* Fixed not return issue and not free issue in example.\n* Renamed ntb_devices to communication_devices to be more generic in\n usertools.\n* Polish the codes and docs.\n\nXiaoyun Li (6):\n raw/ntb: introduce ntb rawdev driver\n raw/ntb: add intel ntb support\n raw/ntb: add handshake process\n examples/ntb: enable an example for ntb\n usertools/dpdk-devbind.py: add support for ntb\n doc: update docs for ntb driver\n\n MAINTAINERS | 8 +\n config/common_base | 5 +\n doc/guides/rawdevs/index.rst | 1 +\n doc/guides/rawdevs/ntb_rawdev.rst | 41 +\n doc/guides/rel_notes/release_19_08.rst | 16 +\n doc/guides/sample_app_ug/index.rst | 1 +\n doc/guides/sample_app_ug/ntb.rst | 47 +\n drivers/raw/Makefile | 1 +\n drivers/raw/meson.build | 2 +-\n drivers/raw/ntb_rawdev/Makefile | 28 +\n drivers/raw/ntb_rawdev/meson.build | 8 +\n drivers/raw/ntb_rawdev/ntb_hw_intel.c | 368 ++++++++\n drivers/raw/ntb_rawdev/ntb_hw_intel.h | 86 ++\n drivers/raw/ntb_rawdev/ntb_rawdev.c | 849 ++++++++++++++++++\n drivers/raw/ntb_rawdev/ntb_rawdev.h | 158 ++++\n .../ntb_rawdev/rte_pmd_ntb_rawdev_version.map | 4 +\n examples/Makefile | 1 +\n examples/meson.build | 21 +-\n examples/ntb/Makefile | 68 ++\n examples/ntb/meson.build | 16 +\n examples/ntb/ntb_fwd.c | 384 ++++++++\n mk/rte.app.mk | 1 +\n usertools/dpdk-devbind.py | 9 +\n 23 files changed, 2112 insertions(+), 11 deletions(-)\n create mode 100644 doc/guides/rawdevs/ntb_rawdev.rst\n create mode 100644 doc/guides/sample_app_ug/ntb.rst\n create mode 100644 drivers/raw/ntb_rawdev/Makefile\n create mode 100644 drivers/raw/ntb_rawdev/meson.build\n create mode 100644 drivers/raw/ntb_rawdev/ntb_hw_intel.c\n create mode 100644 drivers/raw/ntb_rawdev/ntb_hw_intel.h\n create mode 100644 drivers/raw/ntb_rawdev/ntb_rawdev.c\n create mode 100644 drivers/raw/ntb_rawdev/ntb_rawdev.h\n create mode 100644 drivers/raw/ntb_rawdev/rte_pmd_ntb_rawdev_version.map\n create mode 100644 examples/ntb/Makefile\n create mode 100644 examples/ntb/meson.build\n create mode 100644 examples/ntb/ntb_fwd.c" }
