Set $MESA_LOADER_DRIVER_OVERRIDE to "asahi" to make Windows visible. #4

Closed SO5005 closed 1 month ago

Thanks for the PR! The plan was, on krun (the one that runs on the host), detect that we're running on Asahi and then export MESA_LOADER_DRIVER_OVERRIDE. @teohhanhui WDYT?

I had a commit where we were calling LANG=C eglinfo and just looking for EGL driver name: asahi. Is that okay?

It'd be very complex to try to call EGL APIs directly. But sure, we could do it if you don't mind more code... (Will just port it from here: https://github.com/mpv-player/mpv/blob/d347ee0e916de83e74fc4dca1d35300307ce3f6b/video/out/opengl/egl_helpers.c#L313)

I think it's better to just check /proc/device-tree/model or /proc/device-tree/compatible. We can take advantage that GPUs are embedded in this computers so we can safely assume that the asahi mesa driver must be used on them.

@SO5005 do you want to give this approach a try on this PR?
