0. TLDR: $ . oe-init-build-env build-virgl $ bitbake core-image-sato-sdk $ runqemu kvm gl $$ run glxgears or any other GL-capable binary inside qemu
1. qemu is switched over to use gtk frontend. I simply couldn't get SDL frontend to work properly, it only displays a blank black window or doesn't start at all. Same thing happens with qemu binaries provided by Fedora and opensuse (Ubuntu's qemu lacks virgl support). Seems like SDL support has regressed. 2. While the components are built against the most minimum necessary mesa-native set (gbm, egl, dri with no drivers), libepoxy loads and uses the host GL implementation (through a chrpath hack). This is both to save build times, and because the host is likely to have a set of drivers more appropriate for the physical machine (e.g. proprietary nvidia stack, although I didn't test that). 3. I tested this with - glamor X server - weston compositor with drm backend (build core-image-weston, then edit weston.ini in the image to use drm backed instead of fbdev). - kmscube - glxgears - https://www.geeks3d.com/gputest/ The latter two show FPS that is similar to running them directly on the host. 4. Some things I am not sure about: - how much of a 'default' should this be for running qemu. It works for me, but other people might find it less stable compared to the existing sdl-vmware-swrast setup. - what other tests and demos could be run - how could this be tested on the autobuilder. I wrote an oe-selftest for this, but it does require an X session, and ability to create opengl contexts on the host.
