If anyone has any objections, please let me know. ------------------ From: Alex Deucher commit 432e664e7c98c243fab4c3c95bd463bea3aeed28 upstream. 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 Signed-off-by: Greg Kroah-Hartman --- drivers/gpu/drm/amd/amdgpu/amdgpu_bios.c | 5 +++++ 1 file changed, 5 insertions(+) --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_bios.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_bios.c @@ -29,6 +29,7 @@ #include "amdgpu.h" #include "atom.h" +#include #include #include #include @@ -289,6 +290,10 @@ static bool amdgpu_atrm_get_bios(struct if (adev->flags & AMD_IS_APU) return false; + /* ATRM is for on-platform devices only */ + if (dev_is_removable(&adev->pdev->dev)) + return false; + while ((pdev = pci_get_class(PCI_CLASS_DISPLAY_VGA << 8, pdev)) != NULL) { dhandle = ACPI_HANDLE(&pdev->dev); if (!dhandle)
