From b96a6506d0095ef7271b9fadaba2e0dc6ca33484 Mon Sep 17 00:00:00 2001 From: Deepak Nibade Date: Mon, 10 Sep 2018 19:48:14 +0530 Subject: gpu: nvgpu: rename PMU perf unit to pmu_perf Move all files under perf/* to pmu_perf/* since pmu_perf is logically appropriate name for PMU's perf unit Rename perf.c to pmu_perf.c Also rename the HAL from gops.perf to gops.pmu_perf Jira NVGPU-1102 Change-Id: I79e73b8b102ddf6b49783c2f38d861cd43b0b4c6 Signed-off-by: Deepak Nibade Reviewed-on: https://git-master.nvidia.com/r/1819301 Reviewed-by: mobile promotions Tested-by: mobile promotions --- drivers/gpu/nvgpu/perf/perf.c | 128 ------------------------------------------ 1 file changed, 128 deletions(-) delete mode 100644 drivers/gpu/nvgpu/perf/perf.c (limited to 'drivers/gpu/nvgpu/perf/perf.c') diff --git a/drivers/gpu/nvgpu/perf/perf.c b/drivers/gpu/nvgpu/perf/perf.c deleted file mode 100644 index 582b2577..00000000 --- a/drivers/gpu/nvgpu/perf/perf.c +++ /dev/null @@ -1,128 +0,0 @@ -/* - * Copyright (c) 2016-2018, NVIDIA CORPORATION.
