The 200mhz freq is probably the actual minimum on these processors. You can check by connecting and disconnecting a power supply and watching the frequencies. The CPU will throttle for...
Could also be a problem with the measurement tool. What does `sudo turbostat -s Bzy_MHz -i 0.1` have to say? (you might need to be on kernel 6.8 for this)
on Ubuntu 24.10 turbostat shows 200-350 minimum, /proc/cpuinfo shows a pretty constant 400MHz but with some dips below. Not sure if it's an issue with measurement or if the CPU...
Everything I've tested seems to tell me that the CPU does actually clock below the advertised minimum. Seems like a bug with the CPU moreso than with our firmware
Solved in v1.0.0-rc4
The GOP driver doesn't support HDMI 2.1 FRL. The port is configured for FRL 10Gbps, so maybe that's why it doesn't work. Although I would expect GOP to fall back...
@macpijan I just tested disabling FRL and disabling the fixed mode feature we enabled for scaling, and it didn't help. I'm not sure what's going wrong here, GPIOs and VBT...
Confirmed resolved by linked PRs, closing
Applies to dGPU models too - on those models the HDMI port is wired to the discrete graphics, so we'd have to somehow handle dual GPUs in UEFI.
Running Intel GOP and Nvidia GOP from the opROM in UEFI, when screen resolutions aren't the same, causes artifacts in the setup menu. The logo is rendered in the topleft...
