Hi, These are a set of patches [v5] which removes semaphores from infiniband. These are part of a bigger effort to eliminate all semaphores from the linux kernel.
v4 --> v5 --------- IB/isert: Replace semaphore sem with completion - Modified changelog to support use of completion IB/mlx5: Simplify completion into a wait_event - Avoid this patch. As umr_context is on the stack, and we are waiting for it to be fully done, it really should be a completion. v3 -> v4: --------- IB/mlx5: Added patch - Replace semaphore umr_common:sem with wait_event IB/mlx5: Fixed a bug pointed out by Leon Romanovsky v2 -> v3: --------- IB/mlx5: Move '&umr_context' into helper fn IB/mthca: Restructure mthca_cmd.c to manage free_head IB/hns: Restructure hns_roce_cmd.c to manage free_head IB/core: Convert completion to wait_event IB/mlx5: Simplify completion into a wait_event v1 -> v2: --------- IB/hns : Use wait_event instead of open coding counting semaphores IB/mthca : Use wait_event instead of open coding counting semaphores IB/mthca : Remove mutex_[un]lock from *_cmd_use_events/*_cmd_use_polling IB/mlx5 : Cleanup, add helper mlx5_ib_post_send_wait v1 --------- IB/core: iwpm_nlmsg_request: Replace semaphore with completion IB/core: Replace semaphore sm_sem with completion IB/hns: Replace semaphore poll_sem with mutex IB/mthca: Replace semaphore poll_sem with mutex IB/isert: Replace semaphore sem with completion IB/hns: Replace counting semaphore event_sem with wait condition IB/mthca: Replace counting semaphore event_sem with wait condition IB/mlx5: Replace counting semaphore sem with wait condition Thanks, Binoy Binoy Jayan (9): IB/core: iwpm_nlmsg_request: Replace semaphore with completion IB/core: Replace semaphore sm_sem with an atomic wait IB/hns: Replace semaphore poll_sem with mutex IB/mthca: Replace semaphore poll_sem with mutex IB/isert: Replace semaphore sem with completion IB/hns: Replace counting semaphore event_sem with wait_event IB/mthca: Replace counting semaphore event_sem with wait_event IB/mlx5: Add helper mlx5_ib_post_send_wait IB/mlx5: Replace semaphore umr_common:sem with wait_event drivers/infiniband/core/iwpm_msg.c | 8 +- drivers/infiniband/core/iwpm_util.c | 7 +- drivers/infiniband/core/iwpm_util.h | 3 +- drivers/infiniband/core/user_mad.c | 20 +++-- drivers/infiniband/hw/hns/hns_roce_cmd.c | 57 +++++++++----- drivers/infiniband/hw/hns/hns_roce_device.h | 5 +- drivers/infiniband/hw/mlx5/main.c | 6 +- drivers/infiniband/hw/mlx5/mlx5_ib.h | 7 +- drivers/infiniband/hw/mlx5/mr.c | 117 ++++++++-------------------- drivers/infiniband/hw/mthca/mthca_cmd.c | 57 ++++++++------ drivers/infiniband/hw/mthca/mthca_cmd.h | 1 + drivers/infiniband/hw/mthca/mthca_dev.h | 5 +- drivers/infiniband/ulp/isert/ib_isert.c | 6 +- drivers/infiniband/ulp/isert/ib_isert.h | 3 +- 14 files changed, 147 insertions(+), 155 deletions(-) -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project
