This is most likely my fault as I'm new to most of this sort of thing. This is
what I did, maybe you'll see where I went wrong:

- Patch
This is the patched version of src/gallium/drivers/radeonsi/si_gfx_cs.c
http://termbin.com/ypet

- Build
I installed this build of mesa to a different prefix, rather than overriding my
system install (I use this computer for work, everything).

System install:
glxinfo |grep Mesa\ 18
OpenGL core profile version string: 4.5 (Core Profile) Mesa 18.3.0-devel
(git-e345247092)
OpenGL version string: 4.4 (Compatibility Profile) Mesa 18.3.0-devel
(git-e345247092)
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 18.3.0-devel
(git-e345247092)

New build:

OpenGL core profile version string: 4.5 (Core Profile) Mesa 18.3.0-devel
(git-a72dbc461b)
OpenGL version string: 4.4 (Compatibility Profile) Mesa 18.3.0-devel
(git-a72dbc461b)
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 18.3.0-devel
(git-a72dbc461b)

- Running:
I then ran Cemu like this:
LD_LIBRARY_PATH=/home/paul/mesa_log/lib/ GALLIUM_HUD="fps" GALLIUM_DDEBUG=1000
wine64 Cemu.exe

I know wine lets you do this because this is how we used to use a fork of mesa
called 'mesa_mild' to get the required compatibility profile prior to mesa 18.2
which provided core compatibility 4.4

If installing to a prefix like that isn't adequate for this testing, let me
know and I'll re-install the OS on an external drive, do a system-wide install
of this patched mesa and try again.
