Ummm Why isn't enabled by default on Cayman GPU's?

I assume you are talking about dpm. It was enabled by default on cayman GPU a while ago, but was disabled due to stability issues. The root cause was found and fixed in 3.16, so now I'm enabling dpm by default again in 3.17.

Big Thanks! Can you say what the issue was? just with few words.

How can i test this on archlinux? Is there any pkgbuild to build drm-next-3.17 kernel?

Just a small typo in the driver:

Ohhh Thanks agd5f, yes I was refering to dpm. Just today I have obtained a cayman gpu. So from what you say I can safely enbale dpm on kernel 3.16.

Thanks.

What cards don't have DPM enabled yet?

Is it just the old r600 level gpus now?

Just use linux-git and change the first source line from

source=('git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git'

to

source=('git://people.freedesktop.org/~agd5f/linux#branch=drm-next-3.17'

Then makepkg, hit enter a few times to accept new default config, ready.

Yes, just the r6xx-based asics.
