Changes since v2: - Disable virgl for virtio-gpu devices - Ensure wayland-proxy-virtwl isn't started before card0 appears - Build everything with musl - Support testing netvm with crosvm in addition to appvms v1: https://spectrum-os.org/lists/archives/spectrum-devel/20220928170128.1583791... v2: https://spectrum-os.org/lists/archives/spectrum-devel/20220930213533.1710618... This series adds the Spectrum-side support for running VMs that can display Wayland windows on the host compositor, using virtio-gpu. There are various small things still to be resolved, but it's ready for other people to try out and test. The easiest way to test this out is to run "vm-start hello-wayland" on the Spectrum host. If everything goes well, a small window with a picture of a cat (hello-wayland) should appear. This window is running in a VM. Currently, Wayland clients more complex than hello-wayland are unlikely to work, due to a couple of upstream bugs: - https://chromium-review.googlesource.com/c/crosvm/crosvm/+/4584252 - https://chromium-review.googlesource.com/c/crosvm/crosvm/+/4684048 With those two fixes applied, I've been able to run much more complex applications, e.g. Krita. But I don't want to keep this waiting any longer, so let's get the basics in, and not block on fixing the remaining upstream problems. This has felt so close for so long, so I'm not going to miss this opportunity. As for what took this so long, mostly it's been stuff that isn't part of this series. Fixing crosvm, refining my cloud-hypervisor vhost-user-gpu implementation, etc. The previous submissions of this series were marked as RFC because there were bits I just wasn't quite happy enough with to merge them at the time — having to use Glibc for certain components, having virgl always enabled, etc. Those things have all been resolved.
