We use Armbian's mainline kernel builds, so those cannot be compared to the ancient vendor kernel builds of Hardkernel, and it is expected that not all hardware features are supported (OOTB), especially the rarely used ones. I checked at the Armbian forum and could not find anyone asking for CEC support.

Actually it seems like the kernel driver itself needs to support it. In the kernel docs I see only older Odroid/meson chips being supported: https://www.kernel.org/doc/html/latest/admin-guide/media/cec.html

But it could be also a different issue: https://github.com/home-assistant/operating-system/pull/1717/files

Is the CEC module available, does it load, and in case does it throw errors?

modinfo cec
modprobe cec
dmesg -l 0,1,2,3

EDIT: Just checked myself: It is builtin, as is the meson DRM driver. Possibly we are bugged from the same issue HA OS was, and need to compile those as modules instead builtin, for whatever reason.

Hi

Thank you for your answer. I am not familiar at all with the modules mecanisms, so I just pasted blindly the commands you suggested :

modinfo cec

name: cec
filename: (builtin)
license: GPL
file: drivers/media/cec/core/cec
description: Device node registration for cec drivers
author: Hans Verkuil [email protected]
parm: debug:debug level (0-2) (int)
parm: debug_phys_addr:add CEC_CAP_PHYS_ADDR if set (bool)

modprobe cec
Nothing on the console

dmesg -l 0,1,2,3

[ 1.923562] genirq: Setting trigger mode 3 for irq 23 failed (meson_gpio_irq_set_type+0x0/0x60)
[ 4.040467] panfrost ffe40000.gpu: error -ENODEV: _opp_set_regulators: no regulator (mali) found
