Intel recommends that libva-1.0.15 goes together with xf86-video-intel-2.17.0 which is planned to be stabilized.
If you agree to have libva-1.0.15 and libva-intel-driver-1.0.15 stable, please CC: arch teams and make this bug block bug 394393.
amd64 : works for me (gma 3100).
amd64 stable, thanks Mepho
Builds fine on x86. Rdeps build fine as well. No hardware to test the functionality. Fine for me to be marked stable on x86.
x86 stable, thanks Myckel
