## AI overview

AMD submitted 17 Linux kernel patches to enable SEV-TIO TDISP for PCIe 6.0 and newer. The work is intended to secure direct I/O device assignment for confidential-computing environments, including AMD Secure Encrypted Virtualization guest VMs, and includes a common TEE Security Manager developed with Intel, Arm, and RISC-V.

## Source excerpt

The newest Linux kernel patches out of AMD for enhancing the upstream support with the new AMD EPYC 9006 "Venice" processors is for enabling SEV-TIO TDISP that is supported with PCI Express 6.0 and beyond...
