This is the series for adding TID RDMA read. Kaike put in a lot of effort into making this more consumable for review so special thanks to him. Allocating resources and tracing are separated out followed by patches which build up the read request. Then we have the patches to receive incoming TID RDMA read requests and handle integration with the RC protocol. See the cover letter of the original posting for more of a detailed overview of TID. https://www.spinics.net/lists/linux-rdma/msg66611.html --- Kaike Wan (17): IB/hfi: Move RC functions into a header file IB/hfi1: TID RDMA flow allocation IB/hfi1: TID RDMA RcvArray programming and TID allocation IB/hfi1: Add the counter n_tidwait IB/hfi1: Add static trace for flow and TID management functions IB/hfi1: Add functions to build TID RDMA READ request IB/hfi1: Set PbcInsertHcrc for TID RDMA packets IB/hfi1: Add functions to receive TID RDMA READ request IB/hfi1: Add a function to build TID RDMA READ response IB/hfi1: Add functions to receive TID RDMA READ response IB/hfi1: Add TID RDMA handlers IB/hfi1: Add functions for restarting TID RDMA READ request IB/hfi1: Increment the retry timeout value for TID RDMA READ request IB/hfi1: Integrate TID RDMA READ protocol into RC protocol IB/hfi1: Add interlock between a TID RDMA request and other requests IB/hfi1: Enable TID RDMA READ protocol IB/hfi1: Add static trace for TID RDMA READ protocol drivers/infiniband/hw/hfi1/chip.c | 2 drivers/infiniband/hw/hfi1/chip.h | 1 drivers/infiniband/hw/hfi1/common.h | 4 drivers/infiniband/hw/hfi1/driver.c | 58 - drivers/infiniband/hw/hfi1/hfi.h | 19 drivers/infiniband/hw/hfi1/init.c | 10 drivers/infiniband/hw/hfi1/qp.c | 5 drivers/infiniband/hw/hfi1/qp.h | 2 drivers/infiniband/hw/hfi1/rc.c | 542 +++++- drivers/infiniband/hw/hfi1/rc.h | 50 + drivers/infiniband/hw/hfi1/tid_rdma.c | 2714 +++++++++++++++++++++++++++++ drivers/infiniband/hw/hfi1/tid_rdma.h | 196 ++ drivers/infiniband/hw/hfi1/trace.c | 52 + drivers/infiniband/hw/hfi1/trace_ibhdrs.h | 2 drivers/infiniband/hw/hfi1/trace_rc.h | 48 + drivers/infiniband/hw/hfi1/trace_tid.h | 758 ++++++++ drivers/infiniband/hw/hfi1/trace_tx.h | 12 drivers/infiniband/hw/hfi1/user_exp_rcv.h | 1 drivers/infiniband/hw/hfi1/verbs.c | 176 ++ drivers/infiniband/hw/hfi1/verbs.h | 61 + drivers/infiniband/hw/qib/qib_rc.c | 7 drivers/infiniband/sw/rdmavt/qp.c | 13 drivers/infiniband/sw/rdmavt/rc.c | 13 include/rdma/ib_hdrs.h | 9 include/rdma/rdma_vt.h | 12 include/rdma/rdmavt_qp.h | 18 include/rdma/tid_rdma_defs.h | 52 + 27 files changed, 4664 insertions(+), 173 deletions(-) create mode 100644 drivers/infiniband/hw/hfi1/rc.h create mode 100644 include/rdma/tid_rdma_defs.h -- -Denny
