Each driver creates for itself all the\nobjects required for communication with the hardware, as well as a\nglobal MR cache that manages memory mappings.\nThe management of the caches separately by the different drivers, is not\nvery efficient. In fact the same memory is managed several times and\neach caching handle is done by doubling the number of drivers, so we\nwant to manage this cache jointly by the common driver.\nThis feature will move management to common driver in two phases.\n\nPhase 1: sharing HW objects between drivers (11 patches)\nThe communication with the hardware - for any MR handle - is conducted\nby the Protection Domain, so we are motivated to share it between the\ndrivers. However, to create it we need to give the context of the\ndevice, so the context must also be shared between the drivers.\nAt this point we will share between the drivers the next trio (CTX, PD,\npdn) to create an infrastructure that will allow sharing of dependent\nobjects, and in particular the global MR cache.\nThe common driver itself will create this trio individually for all\ndrivers, before calling their probe function. As a parameter to the\nprobe function, it will give them a pointer to the structure containing\nthe trio.\n\nPhase 2: sharing global MR cache between drivers (7 patches)\nThe common driver will add to the structure containing the trio also the\nstructure that manages the global MR cache, and will keep a list of such\nstructures for memory management. In each driver, each queue will manage\nits own local MR cache. If the queue does not find its cache, it will\nswitch to searching the global MR cache shared by all. Caching access\nwill be through the pointer that the driver received as a parameter in\nprobing.\n\nDepends-on: series-19267 (\"mempool: add event callbacks\")\nhttps://patchwork.dpdk.org/project/dpdk/list/?series=19267\n\nv2: rebase\n\nMichael Baum (18):\n net/mlx5/windows: fix miss callback register for mem event\n common/mlx5: share basic probing with the internal drivers\n common/mlx5: share common definitions\n common/mlx5: share memory related devargs\n net/mlx5/windows: rearrange probing code\n common/mlx5: move basic probing functions to common\n net/mlx5: remove redundant flag in device config\n common/mlx5: share device context object\n common/mlx5: add ROCE disable in context device creation\n common/mlx5: share the protection domain object\n common/mlx5: share the HCA capabilities handle\n net/mlx5: remove redundancy in MR file\n common/mlx5: add MR ctrl init function\n common/mlx5: add global MR cache create function\n common/mlx5: share MR top-half search function\n common/mlx5: share MR management\n common/mlx5: support device DMA map and unmap\n common/mlx5: share MR mempool registration\n\n drivers/common/mlx5/linux/mlx5_common_os.c | 280 +++++++-\n drivers/common/mlx5/linux/mlx5_common_os.h | 16 +-\n drivers/common/mlx5/linux/mlx5_common_verbs.c | 96 ++-\n drivers/common/mlx5/linux/mlx5_nl.c | 2 +-\n drivers/common/mlx5/linux/mlx5_nl.h | 6 +-\n drivers/common/mlx5/mlx5_common.c | 596 +++++++++++++++---\n drivers/common/mlx5/mlx5_common.h | 96 +--\n drivers/common/mlx5/mlx5_common_defs.h | 45 ++\n drivers/common/mlx5/mlx5_common_mp.h | 11 +\n drivers/common/mlx5/mlx5_common_mr.c | 192 +++++-\n drivers/common/mlx5/mlx5_common_mr.h | 76 ++-\n drivers/common/mlx5/mlx5_common_private.h | 6 -\n drivers/common/mlx5/mlx5_devx_cmds.h | 12 +-\n drivers/common/mlx5/mlx5_malloc.h | 1 -\n drivers/common/mlx5/version.map | 29 +-\n drivers/common/mlx5/windows/mlx5_common_os.c | 245 ++++++-\n drivers/common/mlx5/windows/mlx5_common_os.h | 9 +-\n drivers/compress/mlx5/mlx5_compress.c | 237 ++-----\n drivers/crypto/mlx5/mlx5_crypto.c | 201 +-----\n drivers/crypto/mlx5/mlx5_crypto.h | 6 +-\n drivers/crypto/mlx5/mlx5_crypto_dek.c | 5 +-\n drivers/net/mlx5/linux/mlx5_ethdev_os.c | 6 +-\n drivers/net/mlx5/linux/mlx5_mp_os.c | 12 +-\n drivers/net/mlx5/linux/mlx5_os.c | 511 ++++-----------\n drivers/net/mlx5/linux/mlx5_verbs.c | 99 +--\n drivers/net/mlx5/linux/mlx5_verbs.h | 2 -\n drivers/net/mlx5/meson.build | 1 -\n drivers/net/mlx5/mlx5.c | 241 ++-----\n drivers/net/mlx5/mlx5.h | 57 +-\n drivers/net/mlx5/mlx5_defs.h | 22 +-\n drivers/net/mlx5/mlx5_devx.c | 39 +-\n drivers/net/mlx5/mlx5_flow.c | 6 +-\n drivers/net/mlx5/mlx5_flow_aso.c | 50 +-\n drivers/net/mlx5/mlx5_flow_dv.c | 66 +-\n drivers/net/mlx5/mlx5_flow_verbs.c | 4 +-\n drivers/net/mlx5/mlx5_mr.c | 397 ------------\n drivers/net/mlx5/mlx5_mr.h | 26 -\n drivers/net/mlx5/mlx5_rx.c | 16 +-\n drivers/net/mlx5/mlx5_rx.h | 20 +-\n drivers/net/mlx5/mlx5_rxq.c | 11 +-\n drivers/net/mlx5/mlx5_rxtx.c | 1 -\n drivers/net/mlx5/mlx5_rxtx.h | 27 -\n drivers/net/mlx5/mlx5_rxtx_vec.h | 1 -\n drivers/net/mlx5/mlx5_trigger.c | 8 +-\n drivers/net/mlx5/mlx5_tx.c | 1 -\n drivers/net/mlx5/mlx5_tx.h | 30 +-\n drivers/net/mlx5/mlx5_txpp.c | 23 +-\n drivers/net/mlx5/mlx5_txq.c | 10 +-\n drivers/net/mlx5/windows/mlx5_ethdev_os.c | 12 +-\n drivers/net/mlx5/windows/mlx5_os.c | 402 ++----------\n drivers/regex/mlx5/mlx5_regex.c | 144 +----\n drivers/regex/mlx5/mlx5_regex.h | 27 +-\n drivers/regex/mlx5/mlx5_regex_control.c | 19 +-\n drivers/regex/mlx5/mlx5_regex_fastpath.c | 47 +-\n drivers/regex/mlx5/mlx5_rxp.c | 62 +-\n drivers/vdpa/mlx5/mlx5_vdpa.c | 212 +------\n drivers/vdpa/mlx5/mlx5_vdpa.h | 5 +-\n drivers/vdpa/mlx5/mlx5_vdpa_event.c | 25 +-\n drivers/vdpa/mlx5/mlx5_vdpa_lm.c | 6 +-\n drivers/vdpa/mlx5/mlx5_vdpa_mem.c | 13 +-\n drivers/vdpa/mlx5/mlx5_vdpa_steer.c | 11 +-\n drivers/vdpa/mlx5/mlx5_vdpa_virtq.c | 15 +-\n 62 files changed, 2075 insertions(+), 2779 deletions(-)\n create mode 100644 drivers/common/mlx5/mlx5_common_defs.h\n delete mode 100644 drivers/net/mlx5/mlx5_mr.c\n delete mode 100644 drivers/net/mlx5/mlx5_mr.h", "diff": null, "prefixes": [ "v2", "00/18" ] }
