[POC PATCH 0/6] guest_memfd in-place conversion selftests for SNP

[Ackerley Tng]

With these POC patches, I was able to test the set memory
attributes/conversion ioctls with SNP. The content policies work :)

Ackerley Tng (6):
  KVM: selftests: Initialize guest_memfd with INIT_SHARED
  KVM: selftests: Call snp_launch_update_data() providing copy of memory
  KVM: selftests: Make guest_code_xsave more friendly
  KVM: selftests: Allow specifying CoCo-privateness while mapping a page
  KVM: selftests: Test conversions for SNP
  KVM: selftests: Test content modes ZERO and PRESERVE for SNP
