AMD Preparing Linux For Enhanced SMT Protection "ESMTP" For EPYC VMs Written by Michael Larabel in AMD on 14 September 2026 at 02:03 PM EDT. Add A Comment AMD engineers today sent out patches on the Linux kernel mailing list for beginning to enable Enhanced SMT Protection "ESMTP" for better security with virtual machines running atop EPYC server processors with SEV-SNP. This is the first time seeing Enhanced SMT Protections on the Linux kernel mailing list. Searching around an ESMTP whitepaper was published on AMD.com earlier this year without attracting much attention. Given the timing of this enablement work, Enhanced SMT Protection is presumably a feature of the AMD EPYC 9006 "Venice" server processors.
