Do you have docs for how to compile a new kernel. I can found below doc link

For the wanland issues, I understood it as comments in #15, that is:
Blur screen for GDM login was caused by wayland, it can be fix by force
to use Xorg in
/etc/gdm3/customer.conf to uncoment WaylandEnable=false
Is this right for your wanland issues on D05?

This issue also occurs on arm64. Attached is a screenshot from a

Why would hibmc_drm be arm64-specific? It is the same PCI device

** Attachment added:
Hisilicon team said this driver (hibmc_drm) are only for arm64. For X86
