Hi guys,
starting with Linux 5.14-rc1 the framebuffer console on Raspberry Pi 3/4 (no U-Boot, multi_v7_defconfig) isn't available anymore. The display shows the rainbow screen from the bootloader and than the HDMI screen goes black instead of kernel messages.
I bisected the issue:

drm: Avoid circular dependencies for CONFIG_FB When cleaning up other drm config dependencies, it is too easy to create larger problems. Instead, mark CONFIG_FB as a "depends": drivers/gpu/drm/Kconfig:74:error: recursive dependency detected!
I compared the changes to the config (based on multi_v7_defconfig) with and without this patch and it shows a lot of changes. Is this intended?

Or with other words should we re-enable CONFIG_FB like this [1] but for Raspberry Pi related configs?

No, just the fbdev emulation but it can work perfectly fine without it.
Or with other words should we re-enable CONFIG_FB like this [1] but for Raspberry Pi related configs?

It should work indeed

If I remember well, this was added some time in the middle of last year, so it wouldn't surprise me that your firmware doesn't support it.
It's not really harmful, but it might still be a good idea to upgrade your firmware. The display pipeline has an unflushable FIFO between devices and if we don't take special care when disabling all the devices in that pipeline, we end up with a shift of one pixel for the rest of the system's life.
We have some code to deal with the transition between the firmware and the kernel, but we couldn't make it work reliably so we ended up asking the firmware instead.
So.. Yeah, it's bad if you want to use the displays output, but it not critical either.

I understand. I think it would be nice to give the user a more helpful warning how to possible fix this, because we cannot assume that every system has the latest firmware.
Also i'm not sure if should give this warning once or on every probing attempt.

while chasing a vchiq performance regression, i was possibly able to crash the VPU firmware (2021-04-30T13:47:07) during boot of my Raspberry Pi 3B+ based on 3d7285a335ed + the bcm2835 clock fix. So this is just a warning, it's not totally harmless:
