Question regarding OpenGL 2.1 support and Xorg

[Luís Mendes]

Hi,

I've read that Open GL 2.1 support is available through latest patches for
mesa etnaviv:
[PATCH] etnaviv: add ext_texture_srgb support
https://lists.freedesktop.org/archives/etnaviv/2017-October/001193.html

Could this mean that it is possible to run Xorg without the
xf86-video-armada driver?
It wouldn't make use of the GC320 unit, but it could allow another option
for running X.

Currently the problem seems just to be that etnaviv doesn't support openGL
2.1 causing glamor to fail with:
[    41.867] Require OpenGL version 2.1 or later.
[    41.867] (EE) modeset(0): Failed to initialize glamor at ScreenInit()
time.

as detailed in the log below.
Or I am getting something wrong?

Regards,
Luís
