Help text

This is a driver for the AMD SVSM vTPM protocol that a SEV-SNP guest OS can use to discover and talk to a vTPM emulated by the Secure VM Service Module (SVSM) in the guest context, but at a more privileged level (usually VMPL0). To compile this driver as a module, choose M here; the module will be called tpm_svsm.
