I'm using an ethernet cable to connect the raspberry pi to my laptop, and my wifi in my laptop is working.
My guess is that you have not enabled internet connection sharing on your laptop so it does not know that it has to provide an IP address to your locally connected RPi.

Re: CEC with Full KMS

Thanks.

Would it make sense to have
CONFIG_MEDIA_CEC_RC
as well?

I think it means that things received via CEC could then make their way into ir-keytable and other tools.

Re: CEC with Full KMS

If you want to use Full KMS then we strongly recommend using the 5.10 kernel. It's currently available via rpi-update, but is looking likely to be in apt within a "days to a few weeks" timescales. CEC is behind a kernel build option. It might be worth checking it's enabled on your build v...

That isn't a controller. You're looking at the Ethernet transformer. The model B Pi has an equivalent transformer integrated into the RJ45 socket so this isn't a hint at a future Pi with built-in PoE.

Re: The Raspberry Pi 400 thread!

Is it possible to use POE ? No. I see from Jeff's teardown video (at 4:40) that the new Ethernet controller supports POE+ - so I presume the issue is the lack of wiring inside the Pi400 to take power from there. Supporting the new controller is interesting though ... perhaps it means that the next ...

1.8GHz default clock? Is that a factory overclock, different revision of the chip or parts selected from the premium bin?
Different chip revision - see 5 minutes into Jeff's video

Edit:
same as CM4 ... which is clocked slower.
So does that mean that CM could safely go to 1.8GHz ?

There's no support for ethernet over HDMI, in just the same way there's no support for I2C over HDMI. The only extra HDMI interface that's available is CEC.
