25 * The approach taken for protected VMs is to allow features that are:
26 * - Needed by common Linux distributions (e.g., floating point)
27 * - Trivial to support, e.g., supporting the feature does not introduce or
29 * - Cannot be trapped or prevent the guest from using anyway
33 * Allow for protected VMs:
34 * - Floating-point and Advanced SIMD
35 * - Data Independent Timing
36 * - Spectre/Meltdown Mitigation
47 * Restrict to the following *unsigned* features for protected VMs:
