We only support vga_switcheroo and runtime pm on PX/HG systems so forcing runpm to 1 doesn't do anything useful anyway. Only call vga_switcheroo_init_domain_pm_ops() for PX/HG so that the cleanup path is correct as well. This mirrors what radeon does as well. v2: rework the patch originally sent by Lukas (Alex) Acked-by: Lukas Wunner <lukas@xxxxxxxxx> Reported-by: Lukas Wunner <lukas@xxxxxxxxx> Signed-off-by: Alex Deucher <alexander.deucher@xxxxxxx> Signed-off-by: Lukas Wunner <lukas@xxxxxxxxx> (v1) Cc: stable@xxxxxxxxxxxxxxx Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/gpu/drm/amd/amdgpu/amdgpu_device.c | 2 -- 1 file changed, 2 deletions(-) --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c @@ -2228,8 +2228,6 @@ int amdgpu_device_init(struct amdgpu_dev * ignore it */ vga_client_register(adev->pdev, adev, NULL, amdgpu_vga_set_decode); - if (amdgpu_runtime_pm == 1) - runtime = true; if (amdgpu_device_is_px(ddev)) runtime = true; if (!pci_is_thunderbolt_attached(adev->pdev)) Patches currently in stable-queue which might be from alexander.deucher@xxxxxxx are queue-4.15/drm-amdgpu-add-new-device-to-use-atpx-quirk.patch queue-4.15/drm-amdgpu-add-dpm-quirk-for-jet-pro-v2.patch queue-4.15/drm-amdgpu-only-check-mmbif_iov_func_identifier-on-tonga-fiji.patch queue-4.15/drm-amdgpu-disable-mmhub-power-gating-on-raven.patch queue-4.15/drm-amdgpu-fix-va-hole-handling-on-vega10-v3.patch queue-4.15/drm-amdgpu-avoid-leaking-pm-domain-on-driver-unbind-v2.patch queue-4.15/drm-amdgpu-add-atpx-quirk-handling-v2.patch
