Bug#1106135: linux-image-6.12.29-loong64: display driver of loongson 7A1000/7A2000 bridge chip is not enabled
Package: src:linux
Version: 6.12.29-1
Severity: important
Tags: patch
Linux kernel has included the display controller driver of Loongson ls7a1000/ls7a2000 since v6.6.
Now the kernel from debian doesn't enable it. When booting with monitor connected to the HDMI port
on motherboard with 7A2000 north bridge chip, there is no drm support, gnome can only run with X11
session. Output of ls -l /sys/class/drm/:
total 0
-r--r--r-- 1 root root 16384 May 20 14:47 version
After enabling CONFIG_DRM_LOONGSON, I can run gnome wayland session.
Here is the patch for debian:
