I get confusing information.In Windows [] or Linx cpuid , the tools tell me there is support for encryption.
...
AMD Secure Encryption (0x8000001f):
SME: secure memory encryption support = true
SEV: secure encrypted virtualize support = true
VM page flush MSR support = true
SEV-ES: SEV encrypted state support = true
encryption bit position in PTE = 0x33 (51)
physical address space width reduction = 0x5 (5)
number of SEV-enabled guests supported = 0x1fd (509)
minimum SEV guest ASID = 0x1 (1)
...
But MSI and the amd test tool (https://github.com/AMDESE/mem-encryption-tests ) tell me the CPU does not support encryption, and no SME activated after setting mem_encrypt=on kvm_amd.sev=1:
Why cpuid reports encryption is supported?
