Panfrost Changelog

[icecream95]

@icecream95 - you guys are incredible

So what exactly in panfrost is going to benefit from this cooperation as a first thing ?

So far, some Bifrost compiler stuff has already been merged, though that doesn't impact any Pine64 devices.

It turns out there are some hardware features we didn't know existed so had to emulate them, so performance will be improved for some applications, especially those that use fixed function OpenGL features that were impossible to test with the blob driver.

Currently, the most incomplete parts of the driver are in framebuffer descriptors and the draw flags that control fixed-function behaviour before and after shader execution. Knowing all the parts of framebuffer descriptors will allow using more formats and enabling some optimisations, while knowing the draw flags will help with implementing a lot of extensions.
