dev drivers

Known driver bugs for Adreno 3xx (v45,v53, v53 (dev), v66):
glBufferSubData/glMapBufferRange stall driver
glBufferSubData causes new internal buffer - OOM error
Broken dynamic Uniform buffer member access
glVertexAttributePointer with type UNSIGNED_BYTE broken glGetShaderInfoLog returns max 1023 byte string

In many cases, the gpu clock is tied to the processor clock, and sometimes this affects things.

Another thing, Snapdragon is always using governer ondemand, plus there were few articles about Qualcomm's disappointing NEON/VeNum performance
