On my ppc64le machine with 32 hardware threads, this speeds up OpenArena
(1920x1200) from 7.2 fps to 8.1 fps.

OpenGL 3.0 requires RGTC support, and until we have emulation in place,
we should document that requirement.

We now have lowering-code in the mesa state-tracker, meaning we no

There are many subtleties to laying out twiddled images on AGX. Document
the known ones in a central place. Many of the hairy details of
twiddling were discovered by Asahi Lina and Dougall Johnson, many thanks
to them.

Varying interpolation is quite involved in the hardware. Now that I
understand how it works, add some documentation. This documentation is
too long and uses too much fancy formatting to put inline with the XML,
so put in our external documentation space.

This requirement is for ARB_texture_buffer_object_rgb32, which obviously
needs the UNIFORM_TEXEL_BUFFER bit, not SAMPLED_IMAGE.

It should be more efficient than u_blitter since it skips
vertex shader stage. Also it's a prerequisite for supporting
MSAA since u_blitter can't do MSAA resolve for us.

Document how to build and use Panfrost's drm-shim implementation. I hope by
documenting this process, other Mesa developers are better able to test
Panfrost. In particular, this allows developers without Mali hardware to run
shader-db for any Mali target, which may be useful for debugging regressions
from common NIR changes.
drm-shim is not a substitute for testing against real hardware.
Special thanks to Emma Anholt and Icecream95 for building this infrastructure.

The optimized routine documented the tiling format together with the software
algorithm. The reference implementation wants the tiling format alone
documented. Let's break out the high level documentation into somewhere
centrally accessible, and refocus the comments in the optimized file on the
optimization.
This documentation is linked bidirectionally with both implementations, so it
should be easy to find.

RADV is the last driver in Mesa that doesn't have a webpage somewhere
that we can link to from mesa3d.org. So let's make a minimal docs article
for it where we link to relevant information elsewhere.

The multiViewport feature isn't required for GL 4.3, it's required for
GL 4.1. Technically speaking, we could have just dropped it because we
already list the maxViewports requirement. But it seems better to be
very clear here to me.

Since this text was written, VirGL has become a shipping, production
quality solution. It's no longer a research project. Let's update the
text to reflect that.
While we're at it, let's drop the project from the page title, as this
is no longer the docs for the entire project.
