Intel Blackhole Render Support Lands In Mesa 20.1
Intel Blackhole Render support was finally merged today for the new Intel "Iris" Gallium3D OpenGL driver default, the older i965 driver for pre-Broadwell hardware, and also the Mesa state tracker for Gallium3D drivers.
Proposed back in 2018 was the Intel blackhole render extension for OpenGL / GLES as an extension to disable all rendering operations emitted to the GPU through OpenGL rendering commands but without affecting OpenGL pipeline operations.
That extension, INTEL_blackhole_render, saw patches back around that point while now finally for Mesa 20.1-devel this Intel OpenGL extension is seeing mainline support for all drivers.
The INTEL_blackhole_render extension is principally useful for debugging / driver optimization analysis purposes. One of the driving motivators appears to be for analyzing the Intel kernel driver execbuffer overhead.
So INTEL_blackhole_renderer is now the latest OpenGL extension in Git for next quarter's Mesa 20.1.
