Multiple "fdee0000.hdmi_receiver: hdmirx_wait_lock_and_get_timing: HDMI pull out, return" on boot

[ArtP]

After upgrading to kernel 6.10.1-edge-rockchip-rk3588 I started getting:

fdee0000.hdmi_receiver: hdmirx_wait_lock_and_get_timing: HDMI pull out, return

on the console. This repeats constantly and quite rapidly, and just doesn't stop. I can silence it by plugging a monitor into HDMI port, but...

I prefer to run my board headless (serial + net). Does anybody know any other way to get rid of this?

This "feature" was absent with the -rc7 kernel.

It will get fixed by this PR: https://github.com/armbian/build/pull/7015

 

If you don't want to wait approval of the PR, copy this overlay https://github.com/efectn-forks/build/blob/rk3588-edge-v6.11/patch/kernel/archive/rockchip-rk3588-6.11/overlay/rockchip-rk3588-hdmirx.dtso & replace okay with disabled and then add if as an user overlay using armbian-add-overlay -> https://docs.armbian.com/User-Guide_Allwinner_overlays/

I noticed the same and since I mainly run server stuff and don't rely on a monitor, my current workaround is modprobe -r synopsys_hdmirx. Don't know what this module is for, but console output is still working via hdmi.

 

And to do it permanently, I have the following:

root@dumpster ~# cat /etc/modprobe.d/hdmi.conf
blacklist synopsys_hdmirx
