Raspberry Pi's Open-Source VC4 Graphics Driver Seeing More Performance Work

Eric Anholt at Broadcom has been focusing his latest VC4 driver efforts on performance tuning.

In Eric's latest weekly update on this open-source DRM+Gallium3D driver stack for the Broadcom SoCs used in the Raspberry Pi, he shares that he's been taking to performance tuning.

Multi-threaded fragment shaders support landed in DRM-Next and Mesa Git, some small performance fixes are comming for 3DMMES Taiji, a fix for folding ALU operations into texture coordinate writes, and other fixes/optimizations that range from 1~2% to around 8% improvements in OpenGL performance.

All the details on this latest performance work for VC4 via Eric's blog.
