From d240cd9eddd943dbe0267d081697195ff1e90b65 Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Tue, 3 Apr 2018 13:05:03 -0400 Subject: drm/amdgpu: optionally do a writeback but don't invalidate TC for IB fences MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is a new IB flag that enables this new behavior. Full invalidation is unnecessary for RELEASE_MEM and doesn't make sense when draw calls from two adjacent gfx IBs run in parallel. This will be the new default for Mesa. v2: bump the version Signed-off-by: Marek Olšák Reviewed-by: Christian König Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_fence.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_fence.c') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_fence.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_fence.c index 97449e06a242..d09fcab2398f 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_fence.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_fence.c @@ -131,7 +131,8 @@ static u32 amdgpu_fence_read(struct amdgpu_ring *ring) * Emits a fence command on the requested ring (all asics). * Returns 0 on success, -ENOMEM on failure. */ -int amdgpu_fence_emit(struct amdgpu_ring *ring, struct dma_fence **f) +int amdgpu_fence_emit(struct amdgpu_ring *ring, struct dma_fence **f, + unsigned flags) { struct amdgpu_device *adev = ring->adev; struct amdgpu_fence *fence; @@ -149,7 +150,7 @@ int amdgpu_fence_emit(struct amdgpu_ring *ring, struct dma_fence **f) adev->fence_context + ring->idx, seq); amdgpu_ring_emit_fence(ring, ring->fence_drv.gpu_addr, - seq, AMDGPU_FENCE_FLAG_INT); + seq, flags | AMDGPU_FENCE_FLAG_INT); ptr = &ring->fence_drv.fences[seq & ring->fence_drv.num_fences_mask]; /* This function can't be called concurrently anyway, otherwise -- cgit v1.2.3
