Issues with Lenovo Yoga Slim 7 ProX (AMD Ryzen 6800HS) #7620

Closed dylangerdaly closed 2 years ago

Qubes OS release

R4.1 (ISO built with kernel-latest - 5.18.9-1) - https://builds.sr.ht/~dylanger/job/804051

Brief summary

Following on from https://github.com/QubesOS/qubes-issues/issues/7570, in order to install and boot, I'm required to add dom0_max_vcpus=1 dom0_vcpus_pin to dom0's CMDLINE, this is similar to what I had to do when Ryzen 4000 series laptops had just come out

When I attempt to start an appVM, any appVM, fedora-36 templateVM for example, the VM starts, then the entire device hangs and resets, I'm unable to view any logs because the entire device resets before I can read logs.

I've submitted a PR to fix the keyboard on Ryzen 6000 platforms here -> https://github.com/QubesOS/qubes-linux-kernel/pull/614

You can download the rpm here: https://builds.sr.ht/~dylanger/job/805565 but you shouldn't trust it.

Getting the same thing on a Ryzen 9 6950HS with kernel 5.18.14-1. Booting template VM causes the system to hang, mouse stops responding, then the system reboots 5 seconds later. Anyone have ideas how to debug further?

Okay so this confirms it's not a Lenovo specific UEFI thing, it's affecting all AMD Ryzen 6000 series CPUs. This is the exact issue I'm having.

I've already written into the xen mailing list however I don't think anyone is running Xen on Ryzen 6000 yet, at all, if I had to guess it fees like a DMA/Memory violation issue.

I'm pleased to say I have Qubes working quite stable on the Yoga Slim 7 ProX (AMD Ryzen 6800HS)

In order to drop the dom0_max_vcpus, you simply add x2apic=false to Xen's CMDLINE this allows Xen to work correctly on AMD Ryzen 6000 Series laptops.

Aside from this, pciback'ing troublesome PCIe devices such as AMD's "Multimedia Controller" fixed the reset issues I was having.

The device is now functional.

I have same processor and It seems like Qubes doesn't support it. Anyone can help me?
