Hi All,
Intel's Trust Domain Extensions (TDX) protect guest VMs from malicious hosts and some physical attacks. TDX has a lot of similarities to AMD SEV. Features like encryption/decryption and string I/O unroll support can be shared between these two technologies.
This patch set adds infrastructure changes required to share the code between AMD SEV and TDX.
Kirill A. Shutemov (1): x86: Move common memory encryption code to mem_encrypt.c
Kuppuswamy Sathyanarayanan (3): x86/sev: Remove sev_enable_key usage in outs##bwl()/ins##bwl() x86/sev: Use CC_ATTR attribute to generalize string I/O unroll x86/sev: Rename mem_encrypt.c to mem_encrypt_amd.c
