There is good explanation to manage pm in the arch wiki : https://wiki.archlinux.org/index.php...th_KMS_enabled

*Turn off SwapbuffersWait
*Force off DRI vsync
*Build the driver with -march=native -O3 -flto
*Compile own kernel with full preemption model
Unfortunately, even then, bug 37168 keeps me on Catalyst. Every few days I try the latest git master stuff and latest kernel to see if it fixes the bug, but nope. That makes r600g unusable for me.
I could go back to mesa 7.10.2 where the bug doesn't manifest, but then the performance is horrid, and it doesn't work with the other 3D apps I run.
It's kinda like how wine works: app "foo" runs fine with wine x.y.z, but with wine x.y.z+1, app "bar" runs fine but "foo" is broken. So you either `make install' a different version of wine each time you want to run one of the different apps, or you just give up and say, eh, too many regressions for me, goodbye.
/me can't seem to get onto SL from work, will have to play around from home at some point.

low:

mid:

memory clock: 1200 MHz
voltage: 1000 mV
high:
current engine clock: 850 MHz
current memory clock: 1200 MHz
voltage: 1200 mV
but I used to have lower frequencies with single monitor in less recent kernel versions. e.g.:
low:
engine clock: 156 MHz
memory clock: 300 MHz
voltage: 950 mV

Originally posted by airlied View Postthe R600 and up GPUs have a power management unit that needs to be programmed, AMD are looking into releasing source code to drive it, but its a lot of code, and I'm sure someone will claim its a big secret. Maybe someone should just RE it already.
