Hi Hiep, This and potential follow on questions are probably best discussed on the Mali forums http://forums.arm.com/index.php?/forum/10-mali-forums/ at least when it comes to the capabilities of the binary driver.

For instance Android as of 2.3 (gingerbread) has EGL and there's certainly no X involved in that use case. The rub as I'm sure you know is that EGL need to be connected to something, X, Wayland, drm... With Mesa for instance configuring with --enable-egl-platforms=drm would do that, however obviously with the mali driver you're not running Mesa and I would imagine that the Mali SDK provides it's own EGL. It'll be a capabilities of that EGL implementation that you'll be interested in. Thus the reference to make a posting to the Mali fora. You do bring up a good use case tho and one that seems well worth documenting in a FAQ. > Hiep -- Regards, Tom "Where's the kaboom!? There was supposed to be an earth-shattering kaboom!"
