Blender on Archlinux ARM with Rockchip RK3288 (XFCE no composite)
After some usage tests (using glmark/glmark-es2), it appears that today, opengl is far faster when composite and OpenGLES driver are disable (remove veyron-gl & xf86-video-armsoc-rockchip packages).
Use XFCE or LXDE destktop. XFCE doesn't use useless candy eyes effects, but it works efficiently.
In practice OpenGL ES is well accelerated (if you don't use composite on your desktop : banish KDE/GNOME and other eyecandy oriented desktop), but barely no application use it. Even ChromeOS and Firefox that could use GLES for WebGL (100% GLES compliant) uses full OpenGL. Only glmark-es2 seems to use OpenGLES (we need to wait Vulkan next month, nobody want to port to GLES today for recoding next month to have more applications).
compositing activate vs not activated:
HW GLES acceleration
glmark2-es2 (GL ES): 12 FPS vs 93 FPS
glmark2 (full GL): 14 FPS vs 53 FPS
HW acceleration disable:
glmark2 ES2: 46 FPS vs 50 FPS
glmark2: 48 FPS vs 56 FPS

The PKGBUILD & patch beside. patch was accepted by blender team, so it will be in next blender release (in few days if there is a 2.76a, or in about 3 month else).
As ArchlinuxARM refused patch, if there is no 2.76a release, you will probably have to wait 3 month for ARMv8 working version, if nothing brake non-x86 build in next Blender release.
