From d0fa84f174770679ea22076f4f754bfde2f3f0e1 Mon Sep 17 00:00:00 2001 From: Lijo Lazar Date: Wed, 21 Sep 2022 17:37:37 +0530 Subject: drm/amdgpu: Disable verbose for p2p dist calc MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Disable verbose while getting p2p distance. With verbose, it shows warning if ACS redirect is set between the devices. Adds noise to dmesg logs when a few GPU devices are on the same platform. Example log: amdgpu 0000:34:00.0: ACS redirect is set between the client and provider (0000:31:00.0) amdgpu 0000:34:00.0: to disable ACS redirect for this path, add the kernel parameter: pci=disable_acs_redir=0000:30:00.0;0000:2e:00.0;0000:33:00.0;0000:2e:10.0 Signed-off-by: Lijo Lazar Reviewed-by: Christian König Reviewed-by: Guchun Chen Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_dma_buf.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_dma_buf.c') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_dma_buf.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_dma_buf.c index 782cbca37538..9e2a4c552a4a 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_dma_buf.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_dma_buf.c @@ -58,7 +58,7 @@ static int amdgpu_dma_buf_attach(struct dma_buf *dmabuf, struct amdgpu_device *adev = amdgpu_ttm_adev(bo->tbo.bdev); int r; - if (pci_p2pdma_distance_many(adev->pdev, &attach->dev, 1, true) < 0) + if (pci_p2pdma_distance_many(adev->pdev, &attach->dev, 1, false) < 0) attach->peer2peer = false; r = pm_runtime_get_sync(adev_to_drm(adev)->dev); -- cgit v1.2.3
