In case you are using Sculpt OS 23.10, I re-published yesterday all packages with the fix. A short smoke test on a Gen12 notebook looks good so far. Cheers, Alex.

Hi Ivan, On 03.01.24 21:48, Ivan Loskutov wrote: I am trying to run seoul demos from genode-world in qemu. It works on my PC but doesn't work on my laptop. The VM is getting stuck on booting.

On PC I have i5-9600K, on laptop - i7-1270P. according to [0] the wrmsr to 0x2ff0 seems to be ADL_UNC_PERF_GLOBAL_CTL, so indeed is Adlerlake specific. Unknown wrmsr accesses are handled as fatal and the Seoul VMM with inject a general protection fault (GP) to the guest. So, you may try to whitelist the access in _handle_wrmsr_intel [2]. At moment the functionality of [0] is not supported/emulated. Cheers, Alex.
