In linux kernel since version 5.10.250 (release Date: 2026-02-11)
The TEE (Trusted Execution Environment) Device Interface
Security Protocol (TDISP) defines a "TSM" as a platform agent
that manages device authentication, link encryption, link
integrity protection, and assignment of PCI device functions
(virtual or physical) to confidential computing VMs that can
access (DMA) guest private memory.
Enable a platform TSM driver to use this capability.
