ESXi 7.0e with Ryzen 5950x

CPUID — Mon, 06 Jun 2022 14:53:26 GMT

I would like to add code to a vSphere virtual machine config file (*.vmx ) like this:

cpuid.0.eax = "0000:0000:0000:0000:0000:0000:0000:1011"
cpuid.0.ebx = "0111:0101:0110:1110:0110:0101:0100:0111"
cpuid.0.ecx = "0110:1100:0110:0101:0111:0100:0110:1110"
cpuid.0.edx = "0100:1001:0110:0101:0110:1110:0110:1001"
cpuid.1.eax = "0000:0000:0000:0001:0000:0110:0111:0001"
cpuid.1.ebx = "0000:0010:0000:0001:0000:1000:0000:0000"
cpuid.1.ecx = "1000:0010:1001:1000:0010:0010:0000:0011"
cpuid.1.edx = "0000:0111:1000:1011:1111:1011:1111:1111"

but that would expose the AVX2 feature of my AMD 5950x Processor. I think the code is masking the AMD Processor with an Intel Processor. Whatever it's doing works, but I need to be able to see (and use) AVX2 inside a guest Virtual Machine.

Can anyone provide similar code to try?

Kind Regards

ps I think this code represents an older duel core processor that does not support AVX so I need the same syntax but a more modern Intel processor. I know i7-7700k works.

Hello CPUID,

By any chance, are you programming? If so, you may visit our Developer Zone (https://www.intel.com/content/www/us/en/developer/overview.html#gs.37ccn6) for support, however, since you are not using an Intel product, you may get better assistance from the app developer or AMD.

Best regards,
