[PATCH 1/4] qemu: capabilities: Introduce QEMU_CAPS_QUERY_DISPLAY_OPTIONS

Peter Krempa pkrempa at redhat.com
Tue Jun 15 10:01:27 UTC 2021 

The command allows to query various display-related options. The absence
of the command will be used to imply certain video-related capabilities
before we would be able to detect them.
