/** @defgroup PerfCntr Performance Counter Functions
 *  These functions are used to configure, query and control performance
 *  counting.
 *
 *  These functions use the same mechanisms as the "perf" command line
 *  utility. They share the same underlying resources and have some similarities
 *  in how they are used. The events supported by this API should have
 *  corresponding perf events that can be seen with "perf stat ...". 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_gpu_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_get_gpu_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_gpu_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_gpu_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_gpu_read_counter() reads an event counter.
 *
 *  Once the counter is no longer needed, the resources it uses should be freed
 *  by calling ::amdsmi_gpu_destroy_counter().
 *
 *
 *  Important Notes about Counter Values
 *  ====================================
 *  - A running "absolute" counter is kept internally. For the discussion that
 *  follows, we will call the internal counter value at time @a t @a
 *  val<sub>t</sub>
 *  - Issuing ::AMDSMI_CNTR_CMD_START or calling ::amdsmi_gpu_read_counter(), causes
 *  AMDSMI (in kernel) to internally record the current absolute counter value
 *  - ::amdsmi_gpu_read_counter() returns the number of events that have occurred
 *  since the previously recorded value (ie, a relative value,
 *  @a val<sub>t</sub> - val<sub>t-1</sub>) from the issuing of
 *  ::AMDSMI_CNTR_CMD_START or calling ::amdsmi_gpu_read_counter()
 *
 *  Example of event counting sequence:
 *
 *  @latexonly
