The Platform Security Processor (PSP) is part of the AMD Secure Processor (AMD-SP) functionality. The PSP is a dedicated processor that provides support for key management commands in Secure Encrypted Virtualization (SEV) mode, along with software-based Trusted Execution Environment (TEE) to enable third-party trusted applications. Note that the key management functionality provided by the SEV firmware can be used outside of the kvm-amd driver hence it doesn't need to depend on CONFIG_KVM_AMD.
