AOSC OS/Retro loongson2f Xorg siliconmotion driver doesn't work

[janprunk]

Bug description

Hello,

I am trying to debug Xorg on a Linux mips loongson2f machine. When I type
"startx" as user or as root, the screen goes black. At that point the
Ctrl+Alt+Fn keypress doesn't react anymore. The screen stays black,
and the Xorg process ends. At that point I am still able to use remote
ssh session, to reboot the machine.

My current /etc/X11/xorg.conf settings are at:
https://termbin.com/pdv7

My /var/log/Xorg.log is at:
https://termbin.com/goju

My gdb trace is at:
https://paste.debian.net/hidden/4adf33e8/

Steps to reproduce

By using /etc/X11/xorg.conf settings from:
https://termbin.com/pdv7
