135 * The actual data counters are read/write. However, writing to the counters
136 * only takes effect if the PMU is enabled. Otherwise the value is stored in
137 * a hardware latch until the next time the PMU is enabled. So we save a copy

139 * disabled. The counter_value_in_latch field is a bitmap indicating which
