This allows\n some runtime type-checking, as well as possible ABI-compatibility support\n in the future as structure change generally involve a change in the size\n of the structure.\n* Ensure all APIs which can return error values have int type, rather than\n void. Since functions like info_get and queue_default_get can now do some\n typechecking, they need to be modified to allow them to return error\n codes on failure.\n\nV2:\n - add additional patch to make start/stop functions optional\n - remove deprecation notice once changes applied\n\nBruce Richardson (7):\n rawdev: add private data length parameter to info fn\n rawdev: allow drivers to return error from info function\n rawdev: add private data length parameter to config fn\n rawdev: add private data length parameter to queue fns\n rawdev: allow queue default config query to return error\n rawdev: mark start and stop functions optional\n doc: remove rawdev deprecation notice\n\n app/test/test_rawdev.c | 2 +-\n doc/guides/rawdevs/ioat.rst | 4 +-\n doc/guides/rawdevs/octeontx2_dma.rst | 2 +-\n doc/guides/rawdevs/octeontx2_ep.rst | 3 +-\n doc/guides/rel_notes/deprecation.rst | 7 ---\n doc/guides/sample_app_ug/ioat.rst | 4 +-\n drivers/bus/ifpga/ifpga_bus.c | 2 +-\n drivers/raw/ifpga/ifpga_rawdev.c | 23 +++++-----\n drivers/raw/ioat/ioat_rawdev.c | 17 ++++---\n drivers/raw/ioat/ioat_rawdev_test.c | 6 +--\n drivers/raw/ntb/ntb.c | 49 ++++++++++++++++-----\n drivers/raw/octeontx2_dma/otx2_dpi_rawdev.c | 7 +--\n drivers/raw/octeontx2_dma/otx2_dpi_test.c | 3 +-\n drivers/raw/octeontx2_ep/otx2_ep_rawdev.c | 7 +--\n drivers/raw/octeontx2_ep/otx2_ep_test.c | 2 +-\n drivers/raw/skeleton/skeleton_rawdev.c | 36 +++++++++------\n drivers/raw/skeleton/skeleton_rawdev_test.c | 32 ++++++++------\n examples/ioat/ioatfwd.c | 4 +-\n examples/ntb/ntb_fwd.c | 7 +--\n lib/librte_rawdev/rte_rawdev.c | 47 +++++++++++++-------\n lib/librte_rawdev/rte_rawdev.h | 27 ++++++++++--\n lib/librte_rawdev/rte_rawdev_pmd.h | 22 ++++++---\n 22 files changed, 201 insertions(+), 112 deletions(-)" }
