DRM VC4 V3D driver for Rasberry Pi 4B.

Postby maigonis » 2020-11-22 12:58

Hi.

I just got my Rasberry Pi 4B SBC and trying out multiple operating systems. As I like Debian a lot I gave it a try and I like it the most, but I have issue is whit GPU,VPU performance. As this is my first Pi I don't know how to enable VC4 V3D driver in https://wiki.debian.org/RaspberryPiImages images. Everything else seems to work just fine, better than official Pi OS is some cases.

Can anyone share knowledge about this issue?

Looks like the driver is developed directly in the upstream Mesa git repositories: https://www.raspberrypi.org/blog/vc4-an ... an-update/

You might need a newer Mesa version than is available in Debian buster. I think the MX Linux AHS repositories have backported a newer version, see viewtopic.php?f=16&t=146083 for a way to add them so you can test my theory.
