Yesterday I upgraded my system to use the following packages:
- xorg-server-1.6.0
- mesa-7.4
- libdrm-2.4.6
and configured video driver to use UXA acceleration. I had to disable "Tilling" option to make this work on my GM45 platform. Otherwise, the display was unusable.

Now, when I use the DisplayPort, I no longer observe the cooling problems I had before. I hope that UXA will work stable on my platform in this configuration.

When do you plan to merge the display-port branch to some release branch? In 2.8?

Thanks,
