Hi everyone.
It looks like 5.7.0-rc7 kernel already has the panfrost drm support.
dmesg:

git mesa already has G-52 support too (it’s still likely initial and the perfomance isn’t optimal)
I’ve tested kmscube - it works great.

But i still have a problem starting. xorg:
1209496.020] (II) glamor: OpenGL accelerated X.org driver based.
[1209496.067] (II) glamor: EGL version 1.4:
[1209496.067] EGL_MESA_drm_image required.
[1209496.068] (EE) modeset(0): glamor initialization failed
[1209496.068] (II) modeset(0): ShadowFB: preferred NO, enabled NO
[1209496.122] (II) modeset(0): Output HDMI-1 has no monitor section
[1209496.176] (II) modeset(0): EDID for output HDMI-1
unfortunately it’s not possible to upload full log.
After that i’ve tested wayland, and it works great!

The main issue is wrong colors
glxinfo and glxgears under wayland with --xwayland support also works great:

It’s also possible to play supertuxkart under wayland with nice perfomance ( colors are wrong too)
So imho the problem is in xorg server (or it’s config), but ubuntu is not my system, i’m not sure if any lib may be missing, so i’m helpless until i can run my favorite distro (WIP).
If anyone knows how to verbose Xorg log to see more details - feel free to share
