FKMS doesn't support hotplug - https://github.com/raspberrypi/linux/blob/rpi-5.10.y/drivers/gpu/drm/vc4/vc4_firmware_kms.c#L1303 will always return connected. What is connected at boot is what you get until you reboot. KMS supports hotplug properly, so changing monitors will...

Under FKMS you could run ```tvservice -M``` to monitor the events as you connect and disconnect the display. I suspect it won't change.

We are aware that shifting to the standard Linux approaches is heavily reliant on devices following the relevant specifications. There are many workaround hacks that have been added to the...

You have that way of getting the Pi to not look at hotplug by modifying /boot/cmdline.txt. The KMS driver did also do an EDID probe as well as checking hotplug,...

Seeing as the change is contained within CONFIG_DRM_TTM which isn't used by vc4 or v3d, the side effects of changing it on a Pi are very minimal. For some reason...

I'd initially made this comment on https://github.com/geerlingguy/raspberry-pi-pcie-devices/issues/2 as it was the earliest Github notification I'd had referencing nouveau WARNs. Duplicating here as it seems to be a better place. I'm...
