Mali has massive driver stalls as soon as you start touching VBOs directly (ex to make dynamic VBOs using glBufferData). There are also a lot of fun and easy ways to shoot yourself in the foot and cause the driver to exhaust memory.
I think mobile GPU drivers in general are pretty much a wasteland, but at least VideoCore is a documented wasteland.
- pcwalton 12y agoFair enough. It's really sad how we have enormous GPU power available in the mobile hardware, but in practice the drivers hold them back so much that that GPU power is really limited.
- TD-Linux 12y agoThere is a lot of work being done on the Mesa NIR-based VideoCore driver. I'll be exciting to see what becomes of it. http://dri.freedesktop.org/wiki/VC4/ http://dri.freedesktop.org/wiki/VC4/
- david-given 12y agoBack in a previous life I was doing OpenGL from the NDK on Android. At least one device could be hard reset by opening a 32-bit config and calling glReadPixels. It wasn't Android's fault; it was a shoddy vendor Mali driver. OpenGLES drivers are much, much better than they used to be (but still very bad).
