Hi all,
FYI: chromium-browser can now also run with GPU acceleration, see: http://forum.odroid.com/viewtopic.php?f=112&t=8267
Steps:
1. Run chromium.
2. Enter about:flags as URL.
3. Disable Override software rendering list (1st one).
4. Close the browser.
5. Run the chromium with "chromium-browser --use-gl=egl" in a terminal/shell
6. Enter about:gpu as URL
You can see it is fully hardware accelerated
Youtube.com plays video. Too bad netflix does not play, because widevine is not supported for armhf.
In order to get a feeling of current GPU performance in X11, see: http://seemore.playcanvas.com/. It takes some time loading, bar progresses slowly. Then click on the menu-icon and select render mode "Albedo" and you should see some GPU rendering. Then click on the statistics-icon to show the performance. I get about 30 fps and that seems a bit slow regarding the GPU processor. Wonder what the fps would be in chrome on Android as a reference.
Also strange that on odroid xu3 they reach twice the fps in X11 with similar hardware (t62x). I feel it has to do with the complete graphics stack, and especially the armsoc ddx being the bottleneck. That is why I asked ARM if they plan to release a mali t76x weston/wayland GBM user space driver for firefly / rk3288 like they did for odroid xu3, see https://community.arm.com/message/37177. That way we would not need armsoc anymore, just weston/xwayland that does more effective and efficient compositing.
