Alex Deucher 18e7c4b1a1 Revert "drm/radeon: disable runtime pm on PX laptops without dGPU power control" ... [ Upstream commit bfaddd9fc8 ] This reverts commit e64c952efb. ATPX is the ACPI method for controlling AMD PowerXpress laptops. There are flags to indicate which methods are supported. If the dGPU power down flag is not supported, the driver needs to implement the dGPU power down manually. We had previously always forced the driver to assume the ATPX dGPU power down was present, but this causes problems on boards where it is not, leading to GPU hangs when attempting to power down the dGPU. Manual dGPU power down is not currently supported in the Linux driver. Some laptops indicate that the ATPX dGPU power down method is not present, but it actually apparently is. I'm not sure if this is a bios bug and it should be set or if there is a reason it was unset and the method should not be used. This is not an issue on other OSes since both the ATPX and the manual driver power down methods are supported. This is apparently fairly widespread, so just revert for now. bugs: https://bugzilla.kernel.org/show_bug.cgi?id=115321 https://bugzilla.kernel.org/show_bug.cgi?id=116581 https://bugzilla.kernel.org/show_bug.cgi?id=116251 Cc: stable@vger.kernel.org Signed-off-by: Sasha Levin <sasha.levin@oracle.com>		History 2016-05-10 12:17:30 -04:00
