Our focus is mainly on Passthrough (and Headless) GPUs for which Virgl is not n= eeded. However, I am assuming you are already collaborating with CrossVM folks on the imple= mentation of these features in Virtio-gpu Linux Guest driver? >> a new DisplayChangeListenerOps implementation, [Kasireddy, Vivek] Could you please elaborate on this? Which backend are yo= u planning to add? I am working on adding a plain and simple Wayland UI backend for Qemu = to reduce the GPU Blits: https://lists.nongnu.org/archive/html/qemu-devel/2021-06/msg06482.html The above version does not have keyboard and mouse support added but I do h= ave a version which does and it is more or less working. However, the only problem I have= run into with this backend is: https://gitlab.freedesktop.org/wayland/weston/-/issues/514 Not sure if you'd run into a similar issue with your use-case or interested= in the Wayland UI backend but I am currently working on trying to come up with a plan to deco= uple OUT_FENCE signalling from atomic pageflip completion event as suggested by Weston ups= tream (Pekka) to fix the above issue.
