From fad061270ac43ff9eed315f0eae7c40b694592de Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Thu, 9 Feb 2017 11:33:37 +0100 Subject: drm/amdgpu: report the number of bytes moved at buffer creation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Like ttm_bo_validate(), ttm_bo_init() might need to move BO and the number of bytes moved by TTM should be reported. This can help the throttle buffer migration mechanism to make a better decision. v2: fix computation Reviewed-by: Christian König Signed-off-by: Samuel Pitoiset Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_object.c | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_object.c') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c index 993c003a42e4..be80a4a68d7b 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c @@ -323,6 +323,7 @@ int amdgpu_bo_create_restricted(struct amdgpu_device *adev, struct amdgpu_bo *bo; enum ttm_bo_type type; unsigned long page_align; + u64 initial_bytes_moved; size_t acc_size; int r; @@ -401,10 +402,15 @@ int amdgpu_bo_create_restricted(struct amdgpu_device *adev, locked = ww_mutex_trylock(&bo->tbo.ttm_resv.lock); WARN_ON(!locked); } + + initial_bytes_moved = atomic64_read(&adev->num_bytes_moved); r = ttm_bo_init(&adev->mman.bdev, &bo->tbo, size, type, &bo->placement, page_align, !kernel, NULL, acc_size, sg, resv ? resv : &bo->tbo.ttm_resv, &amdgpu_ttm_bo_destroy); + amdgpu_cs_report_moved_bytes(adev, + atomic64_read(&adev->num_bytes_moved) - initial_bytes_moved); + if (unlikely(r != 0)) { if (!resv) ww_mutex_unlock(&bo->tbo.resv->lock); -- cgit v1.2.3
