The events * supported by perf can be seen with "perf list" * * The types of events available and the ability to count those * events are dependent on which device is being targeted and if counters are * still available for that device, respectively. * ::amdsmi_dev_counter_group_supported() can be used to see which event types * (::amdsmi_event_group_t) are supported for a given device. Assuming a device * supports a given event type, we can then check to see if there are counters * available to count a specific event with * :: amdsmi_counter_get_available_counters(). Counters may be occupied by other * perf based programs. * * Once it is determined that events are supported and counters are available, * an event counter can be created/destroyed and controlled. * * ::amdsmi_dev_create_counter() allocates internal data structures that will be * used to used to control the event counter, and return a handle to this data * structure. * * Once an event counter handle is obtained, the event counter can be * controlled (i.e., started, stopped,...) with ::amdsmi_control_counter() by * passing ::amdsmi_counter_command_t commands. ::AMDSMI_CNTR_CMD_START starts an * event counter and ::AMDSMI_CNTR_CMD_STOP stops a counter. * ::amdsmi_read_counter() reads an event counter. * * Once the counter is no longer needed, the resources it uses should be freed * by calling ::amdsmi_dev_destroy_counter(). * * * Important Notes about Counter Values * ==================================== * - A running "absolute" counter is kept internally.
