GFXOFF is the new GPU feature that save power consumption. It used RLC to
poweroff the gfx engine dynamicly when there is no workload on gfx pipe and make
gfx into "idle" state.
1. Add three additional RLC ucodes, and use psp to load them.
2. Revise RLC save restore list.
3. Enable CGPG (GFX power gating).
4. Enable gfxoff.
5. Revise suspend/resume sequence.
Currently, only raven is able to support gfxoff at first. And after CQE do
series rounds of testing, and there is no regression that bring by gfxoff
feature till now.
We support two types of gfxoff, and user is able to build them manually from
firmware repo:
1. Real CGPG
$ make clean
$ make REAL_CGPG=1
2. Faked CGPG: (by default)
$ make clean
$ make
Then configure to enable gfxoff with ppfeaturemask=0xffffbfff.
Thanks,
Ray
