From f34a55e497e81347ffbdc6e828f123520d33ce5d Mon Sep 17 00:00:00 2001 From: Mark Zhang Date: Tue, 2 Jul 2019 13:02:42 +0300 Subject: RDMA/core: Get sum value of all counters when perform a sysfs stat read Since a QP can only be bound to one counter, then if it is bound to a separate counter, for backward compatibility purpose, the statistic value must be: * stat of default counter + stat of all running allocated counters + stat of all deallocated counters (history stats) Signed-off-by: Mark Zhang Reviewed-by: Majd Dibbiny Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe --- include/rdma/rdma_counter.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include/rdma') diff --git a/include/rdma/rdma_counter.h b/include/rdma/rdma_counter.h index f2a5c8efc404..bf2c3578768f 100644 --- a/include/rdma/rdma_counter.h +++ b/include/rdma/rdma_counter.h @@ -27,6 +27,7 @@ struct rdma_counter_mode { struct rdma_port_counter { struct rdma_counter_mode mode; + struct rdma_hw_stats *hstats; struct mutex lock; }; @@ -49,5 +50,6 @@ int rdma_counter_bind_qp_auto(struct ib_qp *qp, u8 port); int rdma_counter_unbind_qp(struct ib_qp *qp, bool force); int rdma_counter_query_stats(struct rdma_counter *counter); +u64 rdma_counter_get_hwstat_value(struct ib_device *dev, u8 port, u32 index); #endif /* _RDMA_COUNTER_H_ */ -- cgit v1.2.3
