Hi Lucas,

This is in response to your message
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=968181#14

>B/ RPI4 support in the kernel v3d driver
>(B) requires less work, so should come next quite quickly.

I tried loading v3d.ko to the vanilla 5.10.1 kernel, but
doing so did not bring /dev/dri/render*, which appears and
enables GPU acceleration on Ubuntu kernel for RPi4.

I reported it to 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=977441#27

Bringing GPU acceleration to Debian kernel seems to need some work.

On the other hand, I also have the garbled screen on my 4K HDMI display
as you wrote at

Best regards, Ryutaroh Matsumoto
