21 The ID Registers
24 The Arm architecture specifies a range of *ID Registers* that describe the set
26 the guest's ID registers to the maximum set of CPU features supported by the
27 system. The ID register values may be VM-scoped in KVM, meaning that the
30 KVM allows userspace to *opt-out* of certain CPU features described by the ID
31 registers by writing values to them via the ``KVM_SET_ONE_REG`` ioctl. The ID
34 are mutable in the ID registers using the ``KVM_ARM_GET_REG_WRITABLE_MASKS``.
