drm/radeon/kms/pm: rework power management
- Separate dynpm and profile based power management methods. You can select the pm method by echoing the selected method ("dynpm" or "profile") to power_method in sysfs. - Expose basic 4 profile in profile method "default" - default clocks "auto" - select between low and high based on ac/dc state "low" - DC, low power mode "high" - AC, performance mode The current base profile is "default", but it should switched to "auto" once we've tested on more systems. Switching the state is a matter of echoing the requested profile to power_profile in sysfs. The lowest power states are selected automatically when dpms turns the monitors off in all states but default. - Remove dynamic fence-based reclocking for the moment. We can revisit this later once we have basic pm in. - Move pm init/fini to modesetting path. pm is tightly coupled with display state. Make sure display side is initialized before pm. - Add pm suspend/resume functions to make sure pm state is properly reinitialized on resume. - Remove dynpm module option. It's now selectable via sysfs. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
