What have you tried nouveau on?

I only have a really old NV44 laptop.

The missing intel files had also been reported by prlw1@, I had been
trying to work out where to put the intel_perf files.

I got most of the way through adding files for Intel Iris and Crocus
but I don't think they are supported by the kernel code so stopped.

I see you have made the switch now, not suggesting you revert.

I have been using HAVE_MESA_VER=21 on a Radeon 5450 as well with no
problems.

Tried amdgpu on a ThinkPad T295, doesn't really work but looks like
kernel problems, maybe fixed by a DRI update.

For aarch64, I have been building with LLVMRT disabled so that I could
be sure that the lima or panfrost code was being used, I haven't tried
llvmpipe on it for a while.

Also have the Makefile changes to build libGLESv2 if we wanted to add
that.

I still get a core dump from glxgears on my one nouveau system, this
didn't happen with Mesa 19.
