From ba37a1438aeb540cc48722d629f4b2e7e4398466 Mon Sep 17 00:00:00 2001 From: Michael Roth Date: Mon, 7 Mar 2022 15:33:50 -0600 Subject: x86/sev: Add a sev= cmdline option For debugging purposes it is very useful to have a way to see the full contents of the SNP CPUID table provided to a guest. Add an sev=debug kernel command-line option to do so. Also introduce some infrastructure so that additional options can be specified via sev=option1[,option2] over time in a consistent manner.
