[Mesa-dev] [PATCH 0/4] mesa/i965: Add support for INTEL_blackhole_render

[Lionel Landwerlin]

Hi all,

This series implements a new extension that just landed in the Khronos
repository :

https://github.com/KhronosGroup/OpenGL-Registry/commit/a4f25a7ec733d397d8ea78794a066ea519493688

The purpose of this extension is mostly to enable a feature that is
used in GPA [1], allowing to disable all rendering. The reasoning
being that you could figure how fast your application/engine could be
if the GPU was rendering really fast, helping you identify potential
bottlenecks.

We have special registers on Gen hardware that we can set to implement
this but this could be implemented in other ways (turning operations
in NO-OPs in your command streamer).

Cheers,
