Doug, please consider this patch set for 4.13. This patch set is aiming to automatically find the optimal queue <-> irq multi-queue assignments in storage ULPs (demonstrated on nvme-rdma) based on the underlying rdma device irq affinity settings. Changes from v3: - Renamed mlx5_disable_msix -> mlx5_free_pci_vectors for symmetry reasons Changes from v2: - rebased to 4.12 - added review tags Changes from v1: - Removed mlx5e_get_cpu as Christoph suggested - Fixed up nvme-rdma queue comp_vector selection to get a better match - Added a comment on why we limit on @dev->num_comp_vectors - rebased to Jens's for-4.12/block - Collected review tags Sagi Grimberg (6): mlx5: convert to generic pci_alloc_irq_vectors mlx5: move affinity hints assignments to generic code RDMA/core: expose affinity mappings per completion vector mlx5: support ->get_vector_affinity block: Add rdma affinity based queue mapping helper nvme-rdma: use intelligent affinity based queue mappings block/Kconfig | 5 + block/Makefile | 1 + block/blk-mq-rdma.c | 54 ++++++++++ drivers/infiniband/hw/mlx5/main.c | 10 ++ drivers/net/ethernet/mellanox/mlx5/core/en_main.c | 14 +-- drivers/net/ethernet/mellanox/mlx5/core/eq.c | 9 +- drivers/net/ethernet/mellanox/mlx5/core/eswitch.c | 2 +- drivers/net/ethernet/mellanox/mlx5/core/health.c | 2 +- drivers/net/ethernet/mellanox/mlx5/core/main.c | 114 +++------------------ .../net/ethernet/mellanox/mlx5/core/mlx5_core.h | 1 - drivers/nvme/host/rdma.c | 29 ++++-- include/linux/blk-mq-rdma.h | 10 ++ include/linux/mlx5/driver.h | 2 - include/rdma/ib_verbs.h | 25 ++++- 14 files changed, 152 insertions(+), 126 deletions(-) create mode 100644 block/blk-mq-rdma.c create mode 100644 include/linux/blk-mq-rdma.h -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
