7 * struct intel_pqr_state - State cache for the PQR MSR
8 * @rmid: The cached Resource Monitoring ID
9 * @closid: The cached Class Of Service ID
10 * @rmid_usecnt: The usage counter for rmid
12 * The upper 32 bits of MSR_IA32_PQR_ASSOC contain closid and the
13 * lower 10 bits rmid. The update to MSR_IA32_PQR_ASSOC always
14 * contains both parts, so we need to cache them.
16 * The cache also helps to avoid pointless updates if the value does
