IMPORTANT NOTE: this series should be applied on top of my previous series "Introduce a shared base for application VMs" [1]. This is a bit inconvenient I know, but I haven't committed the other series yet due to wanting to take a second pass at it. Changes since v1: - Fix syntax in img/app development Makefile target. - Enable virgl for virtio-gpu devices (see below). v1: https://spectrum-os.org/lists/archives/spectrum-devel/20220928170128.1583791... Introduction ------------ 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, virgl is enabled for all virtio-gpu devices. This means that all VMs will have GPU acceleration enabled. This is currently required to work around what appears to be a kernel bug that causes applications to freeze, but is likely not something we want to be enabling by default once that's fixed. I have tested with hello-wayland, as in the appvm provided as a demonstration here, and also with foot (by replacing hello-wayland with foot in that VM). I haven't done enough testing with this version of the code to guage how reliably they work yet. [1]: https://spectrum-os.org/lists/archives/spectrum-devel/20220919073659.1703271...
