vc4 and v3d module not loaded

[miskol]

I am testing ubuntu 21.04 beta on raspberry pi 4
and after installation and also after restart
vc4 v3d kernel module isn't loaded
So 3d acceleration don't work

uname -a
Linux misko-desktop 5.11.0-1004-raspi #4-Ubuntu SMP PREEMPT Mon Mar 22 15:51:28 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux

Which image are you using, desktop or server? What's the content of /boot/firmware/config.txt?

[miskol (xlazom00)]

http://cdimage.ubuntu.com/releases/21.04/beta/ubuntu-21.04-beta-preinstalled-desktop-arm64+raspi.img.xz
And config.txt looks like this
[pi4]
max_framebuffers=2

[all]
kernel=vmlinuz
cmdline=cmdline.txt
initramfs initrd.img followkernel

I don't have problem with hirsute-budgie-preinstalled-desktop-arm64+raspi.img

And this bug should be fix only for ubuntu Hirsute Hippo

[miskol (xlazom00)]

Older ubuntu versions don't have kernel with fixed vc4 v3d modules

[Juerg Haefliger (juergh)]

The problem is due to LP: #1918110. A fix for that was released today so you should update and rerun flash-kernel (if it doesn't run automatically).

I don't understand your comment #4.

[miskol (xlazom00)]

Are there any daily builds for raspbery pi ?

for my comment
I saw this:
Changed in linux-raspi (Ubuntu Groovy)
But It is should ubuntu Hirsute I think

[Juerg Haefliger (juergh)]

Ah yes, you're right, thanks. I removed Groovy and added instead Hirsute.

Daily hirsute images:

[miskol (xlazom00)]

Any reason why images from http://cdimage.ubuntu.com/daily-preinstalled/20210409/
don't have it fixed aleardy ???
and still I need to call flash-kernel to fix it?

[miskol (xlazom00)]

I am checking 21.04 release image
and bug is still there

[miskol (xlazom00)]

I need to run sudo flash-kernel to fix it :(

[Juerg Haefliger (juergh)]

It seems the image build process is still broken. It's not a kernel problem and flash-kernel is fixed. Which you've confirmed by running flash-kernel manually which fixes the issue. I'm going to close this ticket, since it's not a kernel problem.

[Dave Jones (waveform)]

Yes, flash-kernel was indeed fixed but there was an issue in the gadget I'd missed.

In the end it's not affecting the desktop image as initial user setup winds up implicitly running flash-kernel anyway, but it's certainly an issue for anyone installing a desktop on top of the server image (up until the first time flash-kernel is run anyway). I've added a note to the hirsute release notes, and patched the gadget accordingly (https://github.com/snapcore/pi-gadget/commit/7c06269154195c500b0f1027bc4d180c964501ed which I'll cherry-pick to the relevant branches).

[miskol (xlazom00)]

I did fresh install of ubuntu 21.04 desktop on pi
And I don't see drivers when I run lsmod
Only sudo flash-kernel will fix it
