From b1ee5998a5d2bb16fb2bb9a03a30a83a55012b92 Mon Sep 17 00:00:00 2001 From: Sanjay R Mehta Date: Fri, 15 Feb 2019 09:20:30 +0000 Subject: NTB: ntb_perf: Disable NTB link after clearing peer XLAT registers If ntb link disabled before clearing peer's XLAT register, the clearing won't have any effect since the link is already down. So modified the sequence so that the link is down only towards the end of the function after clearing the XLAT register Signed-off-by: Sanjay R Mehta Acked-by: Allen Hubbe Acked-by: Logan Gunthorpe Acked-by: Serge Semin Signed-off-by: Jon Mason --- drivers/ntb/test/ntb_perf.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'drivers/ntb') diff --git a/drivers/ntb/test/ntb_perf.c b/drivers/ntb/test/ntb_perf.c index 5ed84376ae56..32a70b6491cd 100644 --- a/drivers/ntb/test/ntb_perf.c +++ b/drivers/ntb/test/ntb_perf.c @@ -734,8 +734,6 @@ static void perf_disable_service(struct perf_ctx *perf) { int pidx; - ntb_link_disable(perf->ntb); - if (perf->cmd_send == perf_msg_cmd_send) { u64 inbits; @@ -752,6 +750,8 @@ static void perf_disable_service(struct perf_ctx *perf) for (pidx = 0; pidx < perf->pcnt; pidx++) flush_work(&perf->peers[pidx].service); + + ntb_link_disable(perf->ntb); } /*============================================================================== -- cgit v1.2.3
