[Qemu-devel] [RFC 0/2] Use SDL to create an OpenGL ES context for virglrenderer.

[Elie Tournier <tournier.elie@gmail.com>]

Hello everyone,

At Collabora, we are working on adding an OpenGL ES backend on virglrenderer [1].
I submit these patches as an RFC because our work didn't land in virglrenderer yet.
Currently, we support OpenGL ES 2.0 on the guest side and OpenGL ES 3.0 on the host side.
Our plan is to increase the guest support to OpenGL ES 3.0.
Thanks to this work, we are able to run QEMU on system that only support OpenGL ES.

In order to use this feature, we need to create a gles context.
This series add an option (`-display sdl,gles=on`) in the SDL display to create that context.

The source code is available on our gitlab instance.
For virglrenderer [2] and qemu [3].

Feel free to review/comment the series.

Have a nice day,
Elie
