I have built my own image and the mali driver works smoothly in the OS. A score of 100+ in glmark2-es2, not bad. (Do I get to test the new patch when I build my own image?)
However, it is still problematic on the browser side. Both firefox and chromium do not work well in terms of hardware acceleration and WebGL. I got the exact same errors as shown in this thread:

What is the current version of mali driver in the source? I suppose it is r3p0 or r4p0, right? The thread says we need at least r4p1. Not sure if it's true tho.
I'm a newbie and whatever I said may not make sense. Feel free to correct me. Please let me know how I can help (I do not have the skills / experience in these low level stuff tho). Thanks.
