Subject: [PATCH] qemu: caps: Introduce QEMU_EGL_HEADLESS_RENDERNODE capability
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Now that we have QAPI introspection of display types in QEMU upstream,
we can check whether the 'rendernode' option is supported with
egl-headless display type.
