- From previous analysis, EMC voltage is set before AMS loads on Mariko, and will not be set again or changed afterwards.
- sys-clk-OC will take care of setting emc voltage on Mariko once it loads.
- OS will not hang at boot as it always boots with EMC @ 1600 MHz.
- Sys-clk-OC
- Major cleanup in clock_manager, preparing to add basic Erista support.
- Added an experimental CPU & GPU frequency governor.
- Known issue:
- Occasional stuttering is expected: GPU load% metric PMU_GET_GPU_LOAD does not reflect real utilization precisely. Use another metric, some interpolation algo or add min frequency option for improvement.
- Loader
- Addressed an issue for Erista variants: Boot with unmodified Fusee or Hekate, nn::pcv::EmcDvfsPeriodicCompHandler will fail with rc 0x8C5. Fixed by removing 40.8 MHz while retaining 1600.0 MHz MEM table -- however, this means user has to use modified sys-clk.
