For secondary GPUs in laptops, i.e. optimus or powerxpress, we have methods for powering down the GPU completely. This adds support to the drm core for powering back up the GPU on any access from ioctls or sysfs interfaces, and fires a 5s timer to test if we can power the GPU off.
Is there a reason for basically re-inventing the existing Linux dynamic power management layer ?
