There is an issue with the HDMI in that caused the system run with >1 in load with heat and performance issues as a result. (https://github.com/Joshua-Riek/ubuntu-rockchip/issues/606) So short term this is disabled by default.
@Joshua-Riek added some sort of overlay to enable it, dont know how that works though but suspect you need to enable it to get it working again https://github.com/Joshua-Riek/linux-rockchip/commit/03b1f58bd995f0d8a6701d868d3fbfa06ffed5c7
I guess you need to do this kind of thing: https://github.com/Joshua-Riek/ubuntu-rockchip/wiki/Device-Tree-Overlays
overlays=rk3588-hdmirx

Thanks so much @nilo85, that does indeed reenable the hdmi in device - I guess I'll need to keep an eye on load and see how it goes!
Thanks to this thread, i also got HDMI Rx to show up.
One thing differed from the last comment is that the device tree overlay usage has changed. Here's the latest description for ubuntu 24.04: https://github.com/Joshua-Riek/ubuntu-rockchip/wiki/Ubuntu-24.04-LTS#using-a-device-tree-overlay
I ended first locating the device tree overlay:
root@yax-opi5p:~# find /lib/firmware/ -name '*rk3588-hdmirx*'
/lib/firmware/6.1.0-1021-rockchip/device-tree/rockchip/overlay/rk3588-hdmirx.dtbo
Then specify that in file /etc/default/u-boot
in this way:
U_BOOT_FDT_OVERLAYS="device-tree/rockchip/overlay/rk3588-hdmirx.dtbo"
Then sudo u-boot-update
and reboot.
I did it with:
root@yax-opi5p:~# uname -a

A recent update seems to have broken the hdmi in capability at a driver level - there is no /dev/video device, so therefore
v4l2-ctl --list-devices
fails withCannot open device /dev/video0, exiting.
There are quite a few hdmi related errors in dmesg, perhaps some of these are relevant (however I'm also having a few other screen related issues, :
rockchip-hdptx-phy-hdmi fed70000.hdmiphy: hdptx phy pll locked!
phy phy-fed70000.hdmiphy.10: phy poweron failed --> -22
dwhdmi-rockchip fdea0000.hdmi: dw_hdmi_qp_setup hdmi set operation mode failed
or perhaps the only message related to hdmirx:
The test bash script below used to work fine, unfortunately I'm not aware which update seems to have broken the functionality.
Any advice on what to roll back to, or what could have disabled the hdmi would be appreciated!
