How to file a helpful issue

Qubes OS release

4.1

Brief summary

Qubes OS does not support Ryzen 7000 series
More specifically, Xen panic saying that it doesn't known the CPU family n° 25
From my understanding, supporting recent hardware would require upgrading xen+libvirt+dom0
( Started few day ago a work to try to upgrade that, but unsure if I will suceed )

Steps to reproduce

Try to run the qubes installer on a computer with a ryzen 7000 serie

Expected behavior

Qubes installer is running

Actual behavior

Xen panic

@marmarek can the needed Xen patches be backported?

I have made a lot of progress lately, and I am now confident that I will make it work as I want (A lot of work is still required on my side. And a lot of testing.).
It is a major upgrade of many dependencies (dom0 fc37+, xen 4.16+, libvirt 8.9+, qemu 7.1+, python 3.11+), so lot of breaking changes, lot of repository that need to be modified etc etc.

Is that a work that interest the Qubes projet for a futur major upgrade (5.x ? 4.3+ ? ... ) ?
In case it is of interest for Qubes projet, do you know how you want to proceed ?

Qubes 4.2 will include at least Xen 4.17 and libvirt 8.9, part of that is already done here: QubesOS/qubes-vmm-xen#144 QubesOS/qubes-core-libvirt#43. Such major changes will not be supported on 4.1.

@neowutran could the relevant patches be backported to the versions used in R4.1?

I will try to find the set of patches required next week. If I succeed I will post it here.
Before that I am still trying to understand some issue I have with my AM5 motherboard (bios is buggy / unstable & unreliable, but maybe some of the issues could be related to kernel version, will try to rule out that)

Did this work include support for AMD Phoenix CPUs, such as Ryzen 7940HS?
