drm/amdgpu: Prefer shadow rom when available

2025-04-25T08:47:58+00:00

commit 27145f78f56a3178c4f9ffe51c4406d8dd0ca90c upstream. Fetch VBIOS from shadow ROM when available before trying other methods like EFI method.

drm/amdgpu: fix vbios fetching for SR-IOV

2024-09-26T21:04:10+00:00

SR-IOV fetches the vbios from VRAM in some cases. Re-enable the VRAM path for dGPUs and rename the function to make it clear that it is not IGP specific. Fixes: 042658d17a54 ("drm/amdgpu: clean up vbios fetching code") Reviewed-by: Yang Wang Tested-by: Yang Wang Signed-off-by: Alex Deucher

drm/amdgpu: clean up vbios fetching code

After splitting the logic between APU and dGPU, clean up some of the APU and dGPU specific logic that no longer applied. Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher

drm/amdgpu/bios: split vbios fetching between APU and dGPU

2024-09-18T20:15:09+00:00

We need some different logic for dGPUs and the APU path can be simplified because there are some methods which are never used on APUs. This also fixes a regression on some older APUs causing the driver to fetch the unpatched ROM image rather than the patched image.

drm/amdgpu: Reorder to read EFI exported ROM first

On EFI BIOSes, PCI ROM may be exported through EFI_PCI_IO_PROTOCOL and expansion ROM BARs may not be enabled. Choose to read from EFI exported ROM data before reading PCI Expansion ROM BAR. Signed-off-by: Lijo Lazar Reviewed-by: Hawking Zhang Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: don't use ATRM for external devices

2023-11-03T15:59:13+00:00

The ATRM ACPI method is for fetching the dGPU vbios rom image on laptops and all-in-one systems. It should not be used for external add in cards. If the dGPU is thunderbolt connected, don't try ATRM. v2: pci_is_thunderbolt_attached only works for Intel. Use pdev->external_facing instead. v3: dev_is_removable() seems to be what we want Link: https://gitlab.freedesktop.org/drm/amd/-/issues/2925 Reviewed-by: Mario Limonciello Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org
