In addition,\nthe indexes of the queues in hardware are represented by 32-bit compared\nto the rte_flow indexes represented by 16-bit, so the processes need to\nshare some mapping between the indexes.\n\nThese patches allow the external process to provide devargs which enable\nimporting its context and PD, instead of prepare new ones. In addition,\nan API is provided for mapping for the indexes of the queues. \n\nv2:\n- Rebase.\n- Add ABI exception for common/mlx5 library.\n- Correct DevX flag updating.\n- Improve explanations in doc and comments.\n- Remove teatpmd part.\n\n\nMichael Baum (6):\n common/mlx5: consider local functions as internal\n common/mlx5: glue device and PD importation\n common/mlx5: add remote PD and CTX support\n net/mlx5: optimize RxQ/TxQ control structure\n net/mlx5: add external RxQ mapping API\n net/mlx5: support queue/RSS action for external RxQ\n\n devtools/libabigail.abignore | 4 +\n doc/guides/nics/mlx5.rst | 1 +\n doc/guides/platform/mlx5.rst | 37 ++-\n doc/guides/rel_notes/release_22_03.rst | 1 +\n drivers/common/mlx5/linux/meson.build | 2 +\n drivers/common/mlx5/linux/mlx5_common_os.c | 196 ++++++++++++--\n drivers/common/mlx5/linux/mlx5_common_os.h | 7 +-\n drivers/common/mlx5/linux/mlx5_glue.c | 41 +++\n drivers/common/mlx5/linux/mlx5_glue.h | 4 +\n drivers/common/mlx5/mlx5_common.c | 64 ++++-\n drivers/common/mlx5/mlx5_common.h | 23 +-\n drivers/common/mlx5/version.map | 3 +\n drivers/common/mlx5/windows/mlx5_common_os.c | 37 ++-\n drivers/common/mlx5/windows/mlx5_common_os.h | 1 -\n drivers/net/mlx5/linux/mlx5_os.c | 18 ++\n drivers/net/mlx5/mlx5.c | 6 +\n drivers/net/mlx5/mlx5.h | 1 +\n drivers/net/mlx5/mlx5_defs.h | 3 +\n drivers/net/mlx5/mlx5_devx.c | 52 ++--\n drivers/net/mlx5/mlx5_ethdev.c | 18 +-\n drivers/net/mlx5/mlx5_flow.c | 43 ++--\n drivers/net/mlx5/mlx5_flow_dv.c | 14 +-\n drivers/net/mlx5/mlx5_rx.h | 49 +++-\n drivers/net/mlx5/mlx5_rxq.c | 258 +++++++++++++++++--\n drivers/net/mlx5/mlx5_trigger.c | 36 +--\n drivers/net/mlx5/mlx5_tx.h | 7 +-\n drivers/net/mlx5/mlx5_txq.c | 14 +-\n drivers/net/mlx5/rte_pmd_mlx5.h | 50 +++-\n drivers/net/mlx5/version.map | 3 +\n 29 files changed, 821 insertions(+), 172 deletions(-)" }
