Bug Description

Our raspberry pi kernel builds don't include the v3d drm driver
(The relevant diff between the raspbian kernel config and ours)
-CONFIG_DRM_V3D=m
+# CONFIG_DRM_V3D is not set

This means 3D acceleration is unavailable on our Pi 4 images.

Thanks, what version will it appear in please, I would like to test it on (Pi4/arm64)
The last one that got updated/upgraded was 5.4.0-1011-raspi (which I have ignored so far)

NOTE: In order to see this change in the linux config you may want to change
    linux/drivers/gpu/drm/v3d/kconfig

- depends on ARCH_BCM || ARCH_BCMSTB || COMPILE_TEST
+ depends on ARCH_BCM || ARCH_BCMSTB || ARCH_BCM2835 || COMPILE_TEST

ogra, I tried it on bionic originally and it failed:

I am willing to test bionic too if you push me :)

I believe this change is necessary, but not sufficient, to make OpenGL use the GPU on a pi 4 running 20.04. After making the change and trying it, I filed a new bug report:
