Don't set reserved bits in MSR_FMASK

Open arturkow2000 opened this issue 6 months ago • 0 comments

Setting reserved bits causes loader to triple-fault when setting MSR_FMASK at least on Ryzen 4650 when running nested under QEMU/KVM.

With reserved bits cleared (upper half of register) the hypervisor can boot successfully.
