drm/nouveau/acpi: use DSM if bridge does not support D3cold 2016-08-31T06:54:05+00:00 Peter Wu peter@lekensteyn.nl 2016-08-25T23:00:54+00:00 279cf3f23870f7eb8ca071115e06d3d5ca0a2b9e Even if PR3 support is available on the bridge, it will not be used if the PCI layer considers it unavailable (i.e. on all laptops from 2013 and 2014). Ensure that this condition is checked to allow a fallback to the Optimus DSM for device poweroff. Initially I wanted to call pci_d3cold_enable before checking bridge_d3 (in case the user changed d3cold_allowed), but that is such an unlikely case and likely fragile anyway.
