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 <lijo.lazar@xxxxxxx> --- drivers/gpu/drm/amd/amdgpu/amdgpu_device.c | 2 +- drivers/gpu/drm/amd/amdgpu/amdgpu_dma_buf.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c index c04ea7f1e819..f600f3a3fe50 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c @@ -5578,7 +5578,7 @@ bool amdgpu_device_is_peer_accessible(struct amdgpu_device *adev, adev->gmc.aper_base + adev->gmc.aper_size - 1; bool p2p_access = !adev->gmc.xgmi.connected_to_cpu && !(pci_p2pdma_distance_many(adev->pdev, - &peer_adev->dev, 1, true) < 0); + &peer_adev->dev, 1, false) < 0); return pcie_p2p && p2p_access && (adev->gmc.visible_vram_size && adev->gmc.real_vram_size == adev->gmc.visible_vram_size && 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); -- 2.25.1
