Hi Doug, Please find the following patch set from Artemy. This patch set fixes and extends ODP support. This patch set has the following steps: 1. Code simplification for all IB drivers. 2. Three fixes to existing ODP code. 3. Adds generic infrastructure for regions consisting of physically contiguous chunks of arbitrary order. Utilizing this infrastructure added specific treatment to ODP MRs allocated with MAP_HUGETLB. 4. Adds ODP suport to Memory Windows (MW). Memory windows allow the application to have more flexible control over access to its memory. The operation of associating an MW with an MR is called binding. When MW is bound to ODP MR it may cause page fault which should be properly handled. Thanks Changes from v0: * Remove temp variable (pg_shift) in i40iw driver as was suggested by Shiraz Artemy Kovalyov (10): IB: Replace ib_umem page_size by page_shift IB/mlx5: Fix function updating xlt emergency path IB/mlx5: Fix UMR size calculation IB/mlx5: Fix implicit MR GC IB/mlx5: Decrease verbosity level of ODP errors IB/umem: Add contiguous ODP support IB/mlx5: Add contiguous ODP support IB/umem: Add support to huge ODP IB/mlx5: Extract page fault code IB/mlx5: Add ODP support to MW drivers/infiniband/core/umem.c | 17 +- drivers/infiniband/core/umem_odp.c | 81 ++++-- drivers/infiniband/hw/bnxt_re/ib_verbs.c | 12 +- drivers/infiniband/hw/cxgb3/iwch_provider.c | 4 +- drivers/infiniband/hw/cxgb4/mem.c | 4 +- drivers/infiniband/hw/hns/hns_roce_cq.c | 3 +- drivers/infiniband/hw/hns/hns_roce_mr.c | 9 +- drivers/infiniband/hw/hns/hns_roce_qp.c | 3 +- drivers/infiniband/hw/i40iw/i40iw_verbs.c | 10 +- drivers/infiniband/hw/mlx4/cq.c | 2 +- drivers/infiniband/hw/mlx4/mr.c | 6 +- drivers/infiniband/hw/mlx4/qp.c | 2 +- drivers/infiniband/hw/mlx4/srq.c | 2 +- drivers/infiniband/hw/mlx5/mem.c | 13 +- drivers/infiniband/hw/mlx5/mlx5_ib.h | 1 + drivers/infiniband/hw/mlx5/mr.c | 6 +- drivers/infiniband/hw/mlx5/odp.c | 344 +++++++++++++++---------- drivers/infiniband/hw/mthca/mthca_provider.c | 5 +- drivers/infiniband/hw/nes/nes_verbs.c | 4 +- drivers/infiniband/hw/ocrdma/ocrdma_verbs.c | 15 +- drivers/infiniband/hw/qedr/verbs.c | 8 +- drivers/infiniband/hw/vmw_pvrdma/pvrdma_misc.c | 2 +- drivers/infiniband/sw/rdmavt/mr.c | 8 +- drivers/infiniband/sw/rxe/rxe_mr.c | 8 +- include/rdma/ib_umem.h | 8 +- include/rdma/ib_umem_odp.h | 6 +- include/rdma/ib_verbs.h | 1 + 27 files changed, 338 insertions(+), 246 deletions(-) -- 2.12.0 -- 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
