How do I enable CEC on RPi4b?

This may be not entirely Slackware on Aarch64 related, but people here might know.

I want to play with controlling the computer with a TV remote, and it is supposed to be done with the CEC protocol.

It is known that RPi supports CEC, but how do I enable it?

Code:echo 'scan' | cec-client -s -d 1
autodetect FAILEDCode:cec-ctl -l
Failed to open /dev/cec0: No such file or directorybut,

Code:raspinfo | grep cec
hdmi_force_cec_address:0=65535
hdmi_force_cec_address:1=65535So it does know that such a thing as cec exists.
