This series moves the MR cache to use RB tree to store the entries of the cache. By doing so, enabling more flexibility when managing the cache entries. The MR cache will now cache mkeys returned by the user even if they are not from one of the predefined pools, by that allowing restarting applications to reuse their released mkey and improve restart times. v4->v5: - Commit message fix: 'Remove implicit ODP' instead of 'explicit' - Fix return value of init function in case of no ODP in configuration v3->v4: - remove 'change-id' and 'issue' git trailers v2->v3: - Refactor MR cache init flow - Move rb_key decleration to rome unnecessary change in following patches v1->v2: - Rearrange patch order to first introduce the RB-tree and only then introduce the caching of previously non-cachable mkeys v0->v1: - Fix rb tree search from memcmp to dedicated cmp function - Rewording of some commit messages Aharon Landau (2): RDMA/mlx5: Don't keep umrable 'page_shift' in cache entries RDMA/mlx5: Remove explicit ODP cache entry Michael Guralnik (4): RDMA/mlx5: Change the cache structure to an RB-tree RDMA/mlx5: Introduce mlx5r_cache_rb_key RDMA/mlx5: Cache all user cacheable mkeys on dereg MR flow RDMA/mlx5: Add work to remove temporary entries from the cache drivers/infiniband/hw/mlx5/mlx5_ib.h | 38 ++- drivers/infiniband/hw/mlx5/mr.c | 478 +++++++++++++++++++++------ drivers/infiniband/hw/mlx5/odp.c | 40 +-- include/linux/mlx5/driver.h | 1 - 4 files changed, 417 insertions(+), 140 deletions(-) -- 2.17.2
