qemu: add a hint on how to enable CPU render nodes when a suitable GPU is absent
This is particularly useful for llvm-accelerated GL rendering from qemu guest to an offscreen buffer (accessible over vnc or spice) using llvmpipe on the host, rather than using unaccelerated swrast renderer in the guest. This is the best that can be done in the absence of a host GPU with render node support (such as old Matrox cards common in servers, or fully virtualized cloud environments with no GPU at all). Note: even though NVidia blob drivers do support render nodes, they do not support gbm (yet?), and so rendering will fall back to llvmpipe as well even when the system has a 3000 euro NVidia GPU. Cue Linus picture. (From OE-Core rev: 9b1daa173481f7f560e00e0dc22b4010ff1dc0ec) Signed-off-by: Alexander Kanavin <> Signed-off-by: Richard Purdie <>
