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.

Alexander Kanavin (23):
gtk+3: enable native/nativesdk variant
gtk+3: remove the gtk-icon-utils-native recipe
shared-mime-info: update the database also in native builds

gtk-update-icon-cache
pixbufcache.bbclass: remove a dependency loop introduced by enabling
gtk+3-native
meta: add native and nativesdk variants to various recipes to enable
gtk+3-native/nativesdk
libepoxy: enable native/nativesdk variants
mesa: enable native and nativesdk variants
virglrenderer: add a recipe
qemu: enable virglrenderer and glx options for native/nativesdk builds
qemu: drop --with-gtkabi option, as it is no longer supported
mesa-gl: do not enable nativesdk variant to avoid clashes with main
mesa recipe
local.conf.sample: adjust the qemu config to enable gtk+ instead of
sdl
qemu: build target variant with gtk+, and nativesdk variant without
sdl
qemu: remove support for building against host sdl
atk: disable gobject-introspection for nativesdk
qemu: add a gettext-native dependency
libjpeg-turbo: fix nativesdk build in same way as native builds are
qemu: add a patch to avoid a missing include error
runqemu: add support for virgl GL acceleration
runqemu: do not check for GL libraries
qemu: add environment variable wrappers to make qemu look good with
gtk frontend
selftest: add a test for virgl GL acceleration
