If consensus is in favour, I will submit a deprecation notice\nfor the changes for the 20.08 release, so that these ABI/API-breaking\nchanges can be merged in 20.11\n\nThe changes are in two areas:\n* For any APIs which take a void * parameter for driver-specific structs,\n add an additional parameter to provide the struct length. 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\nBruce Richardson (5):\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\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 | 34 ++++++++------\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 | 27 +++++++-----\n lib/librte_rawdev/rte_rawdev.h | 27 ++++++++++--\n lib/librte_rawdev/rte_rawdev_pmd.h | 22 ++++++---\n 16 files changed, 178 insertions(+), 91 deletions(-)" }
