AMD Ryzen 7 8845HS could be incompatible:

"no IOMMU for Dev_Id 0" first goes to Xen Bug

my new laptop with a ryzen 7 8845hs is supposed to feature amd-v but IOMMU keeps troubling xen The Panic on CPU 0 points to: I tried bootoptions x2apic=false, iommu=no-intremap so far booting the device but of course not making HVM usable so not network and no usb… when installing bare metal Fedora 40 i am shown plenty of iommu groups for my pci hardware. so i hope its not locked by the bios somewhat? is this a mapping issue for said dev_id 0? and i could maybe get lucky by tinkerin…
