> > More concretely > - CPU feature (Secure Arbitration Mode: SEAM) as "seam" flag in /proc/cpuinfo In my current patchset we don't have "seam" flag in /proc/cpuinfo. https://lore.kernel.org/kvm/cover.1647167475.git.kai.huang@xxxxxxxxx/T/#m02542eb723394a81c35b9542b2763c783222d594 TDX architecture doesn't have a CPUID to report SEAM, so we will need a synthetic flag if we want to add. If userspace has requirement to use it, then it makes sense to add it and expose to /proc/cpuinfo. But so far I don't know there's any. Thanks -Kai
