Public bug reported: Hi,
The request is to backport 09689703d29a RDMA/mlx5: Do not race with mlx5_ib_invalidate_range during create and destroy with it the below list (divided to four sets) is required. most of the patches applied cleanly above focal tree four exceptions. 1. 806b101b2bfa RDMA/mlx5: Use a dedicated mkey xarray for ODP 2. b91e1751fbce RDMA/mlx5: Simplify how the MR cache bucket is located 3. 1769c4c57548 RDMA/mlx5: Always remove MRs from the cache before destroying them 4. b9358bdbc713 RDMA/mlx5: Fix locking in MR cache work queue the rejected hunks need to be manually applied. The rejected hunks are due to true<-->1 false<-->0 exchange added support for wc (b9358bdbc713) and other minor reasons. set 0: Unrelated code cleanups (needed for applying cleanly the mr cache set) https://patchwork.kernel.org/cover/11170991/ 909624d8db5b IB/cm: Use container_of() instead of typecast 6f26b2ac699c IB/mlx5: Remove unnecessary else statement 2d67c0798821 IB/mlx5: Remove unnecessary return statement 4b2a67362e78 RDMA/mlx5: Group boolean parameters to take less space set 1: Rework the locking and datastructures for mlx5 implicit ODP https://patchwork.kernel.org/cover/11181509/ 46870b2391d5 RDMA/odp: Remove broken debugging call to invalidate_range 09689703d29a RDMA/mlx5: Do not race with mlx5_ib_invalidate_range during create and destroy d561987f34f2 RDMA/mlx5: Do not store implicit children in the odp_mkeys xarray 5256edcb98a1 RDMA/mlx5: Rework implicit ODP destroy b70d785d237c RDMA/mlx5: Avoid double lookups on the pagefault path 3389baa831b6 RDMA/mlx5: Reduce locking in implicit_mr_get_data() 423f52d65005 RDMA/mlx5: Use an xarray for the children of an implicit ODP 54375e738295 RDMA/mlx5: Split implicit handling from pagefault_mr 9162420dde49 RDMA/mlx5: Set the HW IOVA of the child MRs to their place in the tree c2edcd69351f RDMA/mlx5: Lift implicit_mr_alloc() into the two routines that call it 3d5f3c54e7bc RDMA/mlx5: Rework implicit_mr_get_data 74bddb3682f6 RDMA/mlx5: Delete struct mlx5_priv->mkey_table 806b101b2bfa RDMA/mlx5: Use a dedicated mkey xarray for ODP 50211ec9443f RDMA/mlx5: Split sig_err MR data into its own xarray fb985e278a30 RDMA/mlx5: Use SRCU properly in ODP prefetch set 2: Consolidate the mmu notifier interval_tree and locking (only first two patches from this set) https://patchwork.kernel.org/cover/11240081/ 99cb252f5e68 mm/mmu_notifier: add an interval tree notifier 56f434f40f05 mm/mmu_notifier: define the header pre-processor parts even if disabled also needed for applying mr cache set cleanly. 03232cc43cff IB/mlx5: Introduce and use mkey context setting helper routine set 3: MR cache fixes and refactoring https://www.spinics.net/lists/linux-rdma/msg89706.html aad719dcf379 RDMA/mlx5: Allow MRs to be created in the cache synchronously 1c78a21a0c6f RDMA/mlx5: Revise how the hysteresis scheme works for cache filling b9358bdbc713 RDMA/mlx5: Fix locking in MR cache work queue ad2d3ef46d2a RDMA/mlx5: Lock access to ent->available_mrs/limit when doing queue_work a1d8854aae4e RDMA/mlx5: Fix MR cache size and limit debugfs 1769c4c57548 RDMA/mlx5: Always remove MRs from the cache before destroying them b91e1751fbce RDMA/mlx5: Simplify how the MR cache bucket is located 7c8691a396bd RDMA/mlx5: Rename the tracking variables for the MR cache f743ff3b37df RDMA/mlx5: Replace spinlock protected write with atomic var a3cfdd392811 {IB,net}/mlx5: Move asynchronous mkey creation to mlx5_ib fc6a9f86f08a {IB,net}/mlx5: Assign mkey variant in mlx5_ib only 54c62e13ad76 {IB,net}/mlx5: Setup mkey variant before mr create command invocation ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1894977 Title: IBM-iobrick patches for Ubuntu 20.04 Status in linux package in Ubuntu: Incomplete Bug description: Hi, The request is to backport 09689703d29a RDMA/mlx5: Do not race with mlx5_ib_invalidate_range during create and destroy with it the below list (divided to four sets) is required. most of the patches applied cleanly above focal tree four exceptions. 1. 806b101b2bfa RDMA/mlx5: Use a dedicated mkey xarray for ODP 2. b91e1751fbce RDMA/mlx5: Simplify how the MR cache bucket is located 3. 1769c4c57548 RDMA/mlx5: Always remove MRs from the cache before destroying them 4. b9358bdbc713 RDMA/mlx5: Fix locking in MR cache work queue the rejected hunks need to be manually applied.
