From mboxrd@z Thu Jan 1 00:00:00 1970 From: Steve Wise Subject: [PATCH v3 0/3] new ib_drain_qp() API Date: Thu, 11 Feb 2016 14:44:06 -0800 Message-ID: Return-path: Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org Cc: bart.vanassche-XdAiOPVOjttBDgjK7y7TUQ@public.gmane.org List-Id: linux-rdma@vger.kernel.org This series creates new helper API functions for draining a queue pair. It is a rework of an original patch created by Christoph Hellwig as part of the CQ API rework and was dropped to be resubmitted by me with iw_cxgb4 support. Original thread: http://www.spinics.net/lists/linux-rdma/msg30296.html Changes since v2: - created 3 drain API functions: ib_drain_rq(), ib_drain_sq(), and ib_drain_qp() - add provider-specific drain function pointers for the sq and rq - refactored the code a bit - support for IB_DIRECT_POLL CQs Changes since v1: - added comments to the ib_drain_qp() function header specifying the consumer requirements - in __ib_drain_qp(), if the ib_post_send() fails, still wait for the recv wr to drain since we already posted it. - CC the SRP maintainer, bart.vanassche-XdAiOPVOjtvowKkBSvOlow@public.gmane.org --- Steve Wise (3): IB: new common API for draining queues iw_cxgb4: add queue drain functions IB/srp: use ib_drain_rq() drivers/infiniband/core/verbs.c | 144 +++++++++++++++++++++++++++++++++ drivers/infiniband/hw/cxgb4/cq.c | 9 ++- drivers/infiniband/hw/cxgb4/iw_cxgb4.h | 4 + drivers/infiniband/hw/cxgb4/provider.c | 2 + drivers/infiniband/hw/cxgb4/qp.c | 16 ++++ drivers/infiniband/ulp/srp/ib_srp.c | 40 +-------- include/rdma/ib_verbs.h | 5 ++ 7 files changed, 183 insertions(+), 37 deletions(-) -- 2.7.0 -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
