From: Daniel Vetter <daniel.vetter@xxxxxxxx> commit 8a3bddf67ce88b96531fb22c5a75d7f4dc41d155 upstream. This doesn't do anything except auto-init drm_agp support when you call drm_get_pci_dev(). Which amdgpu stopped doing with commit b58c11314a1706bf094c489ef5cb28f76478c704 Author: Alex Deucher <alexander.deucher@xxxxxxx> Date: Fri Jun 2 17:16:31 2017 -0400 drm/amdgpu: drop deprecated drm_get_pci_dev and drm_put_dev No idea whether this was intentional or accidental breakage, but I guess anyone who manages to boot a this modern gpu behind an agp bridge deserves a price. A price I never expect anyone to ever collect :-) Cc: Alex Deucher <alexander.deucher@xxxxxxx> Cc: "Christian König" <christian.koenig@xxxxxxx> Cc: Hawking Zhang <Hawking.Zhang@xxxxxxx> Cc: Xiaojie Yuan <xiaojie.yuan@xxxxxxx> Cc: Evan Quan <evan.quan@xxxxxxx> Cc: "Tianci.Yin" <tianci.yin@xxxxxxx> Cc: "Marek Olšák" <marek.olsak@xxxxxxx> Cc: Hans de Goede <hdegoede@xxxxxxxxxx> Reviewed-by: Emil Velikov <emil.velikov@xxxxxxxxxxxxx> Reviewed-by: Alex Deucher <alexander.deucher@xxxxxxx> Signed-off-by: Daniel Vetter <daniel.vetter@xxxxxxxxx> Signed-off-by: Alex Deucher <alexander.deucher@xxxxxxx> Cc: stable@xxxxxxxxxxxxxxx Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c @@ -1357,7 +1357,7 @@ amdgpu_get_crtc_scanout_position(struct static struct drm_driver kms_driver = { .driver_features = - DRIVER_USE_AGP | DRIVER_ATOMIC | + DRIVER_ATOMIC | DRIVER_GEM | DRIVER_RENDER | DRIVER_MODESET | DRIVER_SYNCOBJ | DRIVER_SYNCOBJ_TIMELINE,
