Subject: [Xen-devel] Ryzen 3xxx works with Windows

Hello All,

I compared the CPUID listings from Ryzen 2700X (attached as tar.xz) to 
3700X and found only very few differences. I added

cpuid = [ "0x80000008:ecx=xxxxxxxxxxxxxxxx0100xxxxxxxxxxxx" ]

to xl.cfg and then Windows runs great with 16 vCPUs. Cinebench R15 score 
is >2050 which is more or less the bare metal value.

Regards Andreas
