Regarding the comming Linux 4.4 release candidate:
- There's a Raspberry Pi KMS driver that's finally landed after the extensive work done by Eric Anholt at Broadcom. Unfortunately for Linux 4.4, this Raspberry Pi kernel graphics driver is just for kernel mode-setting and doesn't yet handle 3D hardware acceleration or power management. Eric is still working on that acceleration code as well as the accompanying VC4 Gallium3D driver.

@Fluffyfreak: FYI: I'll be buying a Raspberry Pi 2 soonish, so if you need any one to test stuff, I can give stuff a go. (My thinking is that I don't need a 3, and a Pi 2 costs almost half as much second hand)

It needs a renderer writing, or we need to switch to using a multiplatform renderer like BGFX as previously discussed, otherwise I think it builds and the modelcompiler runs.
Though I haven't tried it in a long time.

New Raspberry out:

One notable step forward is that for Raspberry Pi 4, we are retiring the legacy graphics driver stack used on previous models. Instead, we’re using the Mesa “V3D” driver developed by Eric Anholt at Broadcom over the last five years. This offers many benefits, including OpenGL-accelerated web browsing and desktop composition, and the ability to run 3D applications in a window under X. It also eliminates roughly half of the lines of closed-source code in the platform.

Of course the 4GB version has sold out already :)

I went through some videos last night on the Pi4, I think this had some interesting benchmarks (second half):

Performance is certainly an issue, but the main problem is finding out what verison of desktop OpenGL it supports.
OpenGL ES (3.0) is not the same thing, that's been pretty much thr only thing stopping us supporting the Pi.
