[SOLVED] Using DRI3 with Radeon

Hello.

I try to activate DRI3 with x86-video-ati driver.

I followed the instructions and I created a file in /etc/X11/xorg.conf.d

20-radeon.conf

Section "Device"
        Identifier  "radeon"
        Driver "radeon"
        Option "AccelMethod"           "Glamor" #valid options are XAA, EXA and Glamor. Default value varies per-GPU.
        Option "DRI3"                  "on" #enable DRI3 instead of the default DRI2-mode
EndSection

Unfortunately the option does not want to activate and my xorg.log tell me :
cat /var/log/Xorg.0.log | grep DRI
[     3.550] (II) glamor: EGL version 1.4 (DRI2):
[     3.643] (II) RADEON(0): [DRI2] Setup complete
[     3.643] (II) RADEON(0): [DRI2]   DRI driver: radeonsi
[     3.643] (II) RADEON(0): [DRI2]   VDPAU driver: radeonsi
[     3.704] (WW) RADEON(0): Option "DRI3" is not used
[     3.708] (II) GLX: Initialized DRI2 GL provider for screen 0

I tried to change the option to "DRI3" "1" or "DRI" "3" but the return of xorg.log still the same.

So, have you ever had a similar trouble? And if yes, how did you resolve it?

Re: [SOLVED] Using DRI3 with Radeon

To  enable DRI3? I'm using the opensource/mesa driver
# nano /etc/pacman.conf
Add first repositories
[mesa-git]
Server = http://pkgbuild.com/~lcarlier/$repo/$arch
pacman -Syy mesa-git
pacman -S xf86-video-ati-git

nano /etc/X11/xorg.conf.d/20-radeon.conf
Section "Device"
        Identifier  "HD7850"
        Driver "radeon"
        option "swapbufferwait" "0"
        Option "ColorTiling" "on"
        Option "DRI3"        "1"
        option "AccelMethod"  "glamor"
Endsection

Re: [SOLVED] Using DRI3 with Radeon

XF86-video-ati 1:7.5.0-2 in [extra] doesn't have DRI3 support yet, you'll have to use xf86-video-ati-git .

Get it from Lordheavy's mesa-git repo (see john29 post just above this one) or use the AUR package.

clean chroot building not flexible enough ?
