Doing that also\nmade possible to store devices references into\na linked list instead of a static array. Last\npatch makes the rte_vdpa_device structure\ncontent opaque to the applications, creating\na clear barrier between application visible\nAPI and drivers visble ones.\n\nThe first two patches fixes issues in some\nbusses iterators, causing segmentation faults\nwhen iterating only on a device class.\n\nWhile reviewing, if you notice further possible\nimprovements, please let me know. Target is to\nremove the experimental tag from vDPA APIs in\nnext LTS release.\n\nThanks to David for giving me some ideas of\nimprovements!\n\nMaxime Coquelin (14):\n bus/dpaa: fix null pointer dereference\n bus/fslmc: fix null pointer dereference\n vhost: introduce vDPA devices class\n vhost: make vDPA framework bus agnostic\n vhost: replace device ID in vDPA ops\n vhost: replace vDPA device ID in Vhost\n vhost: replace device ID in applications\n vhost: remove useless vDPA API\n vhost: use linked-list for vDPA devices\n vhost: introduce wrappers for some vDPA ops\n examples/vdpa: use new wrappers instead of ops\n examples/vdpa: remove useless device count\n vhost: remove vDPA device count API\n vhost: split vDPA header file\n\n drivers/bus/dpaa/dpaa_bus.c | 5 +\n drivers/bus/fslmc/fslmc_bus.c | 5 +\n drivers/vdpa/ifc/ifcvf_vdpa.c | 84 ++++-----\n drivers/vdpa/mlx5/mlx5_vdpa.c | 85 +++++----\n drivers/vdpa/mlx5/mlx5_vdpa.h | 5 +-\n examples/vdpa/main.c | 108 +++++------\n lib/librte_vhost/Makefile | 3 +-\n lib/librte_vhost/meson.build | 3 +-\n lib/librte_vhost/rte_vdpa.h | 172 ++++--------------\n lib/librte_vhost/rte_vdpa_dev.h | 135 ++++++++++++++\n lib/librte_vhost/rte_vhost.h | 20 ++-\n lib/librte_vhost/rte_vhost_version.map | 11 +-\n lib/librte_vhost/socket.c | 48 ++---\n lib/librte_vhost/vdpa.c | 238 ++++++++++++++++---------\n lib/librte_vhost/vhost.c | 19 +-\n lib/librte_vhost/vhost.h | 9 +-\n lib/librte_vhost/vhost_user.c | 28 +--\n 17 files changed, 545 insertions(+), 433 deletions(-)\n create mode 100644 lib/librte_vhost/rte_vdpa_dev.h", "diff": null, "prefixes": [ "00/14" ] }
