Depending on HW generation, BAR that needs to be excluded from pci_resize_resource() is either 2 or 5.
Suggested-by: Christian König <[email protected]> Signed-off-by: Ilpo Järvinen <[email protected]> --- This change should be be folded into the commit 73cd7ee85e78 ("PCI: Fix restoring BARs on BAR resize rollback path") in the pci/resource branch. Also the changelog should be changed: "(BAR 5)" -> "(BAR 2 or 5)". --- drivers/gpu/drm/amd/amdgpu/amdgpu_device.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c index 4e241836ae68..bf0bc38e1c47 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c @@ -1736,7 +1736,9 @@ int amdgpu_device_resize_fb_bar(struct amdgpu_device *adev) pci_release_resource(adev->pdev, 0); - r = pci_resize_resource(adev->pdev, 0, rbar_size, 1 << 5); + r = pci_resize_resource(adev->pdev, 0, rbar_size, + (adev->asic_type >= CHIP_BONAIRE) ? 1 << 5 + : 1 << 2); if (r == -ENOSPC) dev_info(adev->dev, "Not enough PCI address space for a large BAR."); base-commit: 73cd7ee85e788bc2541bfce2500e3587cf79f081 -- 2.39.5
