Without this patch, my server cannot start the DM. It is a Loongson

0000:03:00.0 VGA-compatible controller: ASPEED Technology, Inc.

When not working, there is the following information in dmesg:
loongson 0000:00:06.1: [drm] Private vram start: 0xe00472a6000,
size: 0MiB
Loongson 0000:00:06.1: [drm] *Error* Request (0MiB) failed
Anyway, this patch works fine with my server now, thank you.
Does the sever you are using has a dedicated VRAM for the 0000:00:06.1?
This hardware has no VRAM.
