I can't wait to see benchmarks about this interesting feature Thank you Jerome Glisse!

This is just fantastic! All Linux Radeon users thank you, Jerome
Have a nice break, and please do HiZ if it is your domain. Thanks.

How to enable it? Which option must be added to xorg.conf?

If you have to ask, you probably don't have the skillset to test the patches without exact step by step instructions, which would take too much time (and be too machine-dependent) to be worthwhile.

However, if you must know:

Section Device
Identifier "blah"
Driver "radeon"
Option "ColorTiling2D" "on"
EndSection

Put something like that in /etc/xorg.conf.d/01-heh.conf

NB: If this breaks your X because of invalid syntax or something, I am not responsible! This is untested "air code". You are responsible for figuring out how to debug X and get it working if there's an error.

That would be great! For those who don't know what HiZ stands for, it means Hierarchical Z-Buffer. There is some code to support this feature, but it's stuck since August as you can see here and according to freedesktop's bug report it doesn't work.

Hi-Z seems stalled unfortunately

3.4 is a long wait.

3.4 is a long wait.

This is a large patch, and 3.3 merge windows is closed. I wish it could be faster
