The C-states and P-states data are used to support CPU power management. The hypervisor controls C-states and P-states for a User VM. ACRN userspace need to query the data from the hypervisor to build ACPI tables for a User VM. HSM provides ioctls for ACRN userspace to query C-states and P-states data obtained from the hypervisor.
