Abstract
Mechanisms for controlling rollover or reset of hardware performance counters in the data processing system. A signal indicating that a rollover or reset of a first hardware performance counter has occurred is received and it is determined if the first hardware performance counter is analytically related to one or more second hardware performance counters based on defined ganged hardware performance counter sets. A signal is sent to each of the one or more second hardware performance counters in response to a determination that the first hardware performance counter is analytically related to the one or more second hardware performance counters. Each of the one or more second hardware performance counters is reset to an initial value in response to the one or more second hardware performance counters receiving the signal from the ganged hardware performance counter rollover/reset logic.
