For now we explicitly return -ENODEV for generic bindings. Remove this check once IP discovery based checking is in place. v2: rebase (Alex) Reviewed-by: Christian König <christian.koenig@xxxxxxx> Signed-off-by: Alex Deucher <alexander.deucher@xxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c index f65b4b233ffb..c294081022bd 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c @@ -1952,6 +1952,16 @@ static const struct pci_device_id pciidlist[] = { {0x1002, 0x7424, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CHIP_BEIGE_GOBY}, {0x1002, 0x743F, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CHIP_BEIGE_GOBY}, + { PCI_DEVICE(0x1002, PCI_ANY_ID), + .class = PCI_CLASS_DISPLAY_VGA << 8, + .class_mask = 0xffffff, + .driver_data = 0 }, + + { PCI_DEVICE(0x1002, PCI_ANY_ID), + .class = PCI_CLASS_DISPLAY_OTHER << 8, + .class_mask = 0xffffff, + .driver_data = 0 }, + {0, 0, 0} }; @@ -1999,6 +2009,11 @@ static int amdgpu_pci_probe(struct pci_dev *pdev, return -ENODEV; } + if (flags == 0) { + DRM_INFO("Unsupported asic.
