From 4628d3e178430d418703f39e86d63e22a6af209f Mon Sep 17 00:00:00 2001
Message-Id: <4628d3e178430d418703f39e86d63e22a6af209f@dist-git>

Subject: [PATCH] qemu: caps: Introduce a capability for egl-headless
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Since QEMU 2.10, it's possible to use a new type of display -
egl-headless which uses drm nodes to provide OpenGL support. This patch
adds a capability for that. However, since QEMU doesn't provide a QMP
command to probe it, we have to base the capability on specific QEMU
version.
