FEX falling back to llvmpipe

[MitchellKagerKodiak]

I use the output of vulkaninfo to compare the GPU resolution on my host versus per FEXBash. On my host, I see the expected Turnip/Adreno drivers. Within the FEX shell, I see an llvmpipe fallback. This is also reflected when I check the hardware info in Steam within a FEX environment.

Aside from this, my subsystem seems to be working well -- Steam launches and I can download and run games, albeit with very poor performance.

Is there a specific configuration step I need to take to enable hardware GPU support in my subsystem? I installed i386 driver variants in my host machine.

Retroid Pocket 5, SD 685, Armbian 25.5

The latest FEX rootfs image has Turnip/Freedreno installed through kisak-ppa, which might not have the kgsl freedreno API enabled, only msm. We're waiting for Debian/Ubuntu to fix their llvm packages for i386 to continue building an "everything" driver config. This is usually fine because FEX doesn't support Android although.

This is a common issue for all arm gpu inside soc. FEX is using mesa inside x86 rootfs, and debian/ubuntu don't enable gpu driver inside arm socs like freedreno, panfrost.
