[Mesa-users] Etnaviv support in Mesa

[Gaylord Charles]

Hello Albert,

Thank you for your answer.
In fact, enabling hardware acceleration is the first step. My goal is to
run a WebKit-based browser with WebGL support. I did not plan to use
Wayland and I think that the browser (not chosen yet) could require GLX.

Regards,
Gaylord
