From: Leon Romanovsky <leonro@xxxxxxxxxx> >From Jason: Move the remaining cases working with umems to use versions of ib_umem_find_best_pgsz() tailored to the calculations the devices requires. Unlike a MR there is no IOVA, instead a page offset from the starting page is possible, with various restrictions. Compute the best page size to meet the page_offset restrictions. Thanks Jason Gunthorpe (6): RDMA/mlx5: Use ib_umem_find_best_pgsz() for devx RDMA/mlx5: Use ib_umem_find_best_pgoff() for SRQ RDMA/mlx5: Use mlx5_umem_find_best_quantized_pgoff() for WQ RDMA/mlx5: Use mlx5_umem_find_best_quantized_pgoff() for QP RDMA/mlx5: mlx5_umem_find_best_quantized_pgoff() for CQ RDMA/mlx5: Lower setting the umem's PAS for SRQ drivers/infiniband/hw/mlx5/cq.c | 48 ++++++++--- drivers/infiniband/hw/mlx5/devx.c | 56 ++++++------ drivers/infiniband/hw/mlx5/mem.c | 115 +++++++++---------------- drivers/infiniband/hw/mlx5/mlx5_ib.h | 56 ++++++++++-- drivers/infiniband/hw/mlx5/qp.c | 124 ++++++++++++--------------- drivers/infiniband/hw/mlx5/srq.c | 27 +----- drivers/infiniband/hw/mlx5/srq.h | 1 + drivers/infiniband/hw/mlx5/srq_cmd.c | 80 ++++++++++++++++- include/rdma/ib_umem.h | 42 +++++++++ 9 files changed, 326 insertions(+), 223 deletions(-) -- 2.26.2
