ENGR00220834 Disable GPU IRQ trigger for CPU governor to save power
Disable GPU IRQ trigger for CPU governor to save power
Current GPU trigger will let CPU work at 1G no matter any 3D draw
that make much power waste, to balance power and performance
we desire to disable GPU trigger for CPU governor, this change
will impact some benchmark performance but the drop is acceptable,
android will add performance mode, for any demo or customer who care
performance more than power please select performance mode.
