[Mesa-dev] Broadcom VideoCore IV

[Mohamed MEDIOUNI]

The VideoCore IV GPU has 14 cores:

- 2 VPU Cores : Full-blown cores which run the ThreadX RTOS.
There is an experimental LLVM port to it and also the VBCC C89
compiler(which has'nt time support so classic benchmarks run indefinitely).
The binary blob run on that.
5 GFlops

- 12 QPU Cores : 3D cores officially documented by Broadcom and using a
tile-mode rendering architecture.
The full Android driver for that was open-sourced at the end of February.

24Gflops

Questions:

Can Gallium3D run with tile-mode rendering architecture ?
Is it better using Mesa and  the Broadcom shader compiler ?
Is it better using the VPU and an adapted LLVMpipe ?
