V2 changes: addressed feedback from the first review round V3 changes: - better fix for missing qemu X11 include, as discussed with upstream - maintainers.inc entry for virglrenderer - egl-headless support (see below for details) - improvements to kmscube recipe - fix to vte-native to allow building it with gcc 4.8 V4 changes - address failures uncovered by yocto autobuilder V5 changes - remove patches that have been merged to master - replace BBCLASSEXTEND_remove with PREFERRED_PROVIDER for mesa recipe variants V6 changes - again rebase to master - tweak oe-selftest to remove unnecessary re-builds of qemu-native V7 changes - rename virglrender_git.bb to virglrendender_0.7.0.bb - update the status of virglrenderer patches - further clarify the PACKAGECONFIG settings for qemu
Why this? Why now? 1. I think we are heading towards a reality where some kind of working GL is a 'must' for any kind of UI work. 2. Typically people build images and then transfer them to the NUC or even target boards for testing - using qemu would be less awkward. 3. Current qemu configuration is basically useless here, as it only provides a very slow software GL driver from mesa. 0. TLDR: a) Gtk UI frontend $ . oe-init-build-env build-virgl $ bitbake core-image-sato-sdk $ runqemu kvm gl $$ run glxgears or any other GL-capable binary inside qemu b) egl-headless $ . oe-init-build-env build-virgl $ bitbake core-image-sato-sdk $ runqemu kvm egl-headless publicvnc $ <connect with a vnc viewer to 127.0.0.1:5900> $$ run glxgears or any other GL-capable binary inside qemu 1. For the local UI, 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. What is egl-headless? In this variant, Qemu does not open a UI window at all. Instead, it renders all graphics, including GL, into a memory buffer, which can be seen with a vnc or spice client (over a TCP socket). This has the following advantages: - no need to be physically present at the host machine, output (including GL bits!) can be seen remotely - no need for the host machine to run an X session 3. 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). 4. 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. 5. 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 two oe-selftests for this (gtk, egl-headless), but one of them does require an X session, and both require ability to create opengl contexts on the host.
