Ah, hm. Both OpenBSD and Linux enumerate SEV and SEV-ES among the supported CPU features.
OpenBSD: "cpu0: cpuid 8000001F eax=f<SME,SEV,PFLUSH_MSR,SEVES> ecx=f" Linux /proc/cpuinfo: "... sev sev_es ..." Are the PRO models simply missing the necessary parts from the PSP in order to support SEV all the way? On 2026-09-13 01:59:15 Mike Larkin wrote: > this cpu does not support SEV
