Subject: [PATCH] qemu: caps: Introduce a capability for egl-headless

Since QEMU 2.10, it's possible to use a new type of display -
|
|
|
edecca |
egl-headless which uses drm nodes to provide OpenGL support. This patch
|
|
|
edecca |
adds a capability for that. However, since QEMU doesn't provide a QMP
|
|
|
edecca |
command to probe it, we have to base the capability on specific QEMU
|
|
|
edecca |
version.
