◆ amdsmi_event_type_t

enum amdsmi_event_type_t

Event types Event type enum. Events belonging to a particular event group amdsmi_event_group_t should begin enumerating at the amdsmi_event_group_t value for that group.

Data beats sent to neighbor 0; Each beat represents 32 bytes.

XGMI throughput can be calculated by multiplying a BEATs event such as AMDSMI_EVNT_XGMI_0_BEATS_TX by 32 and dividing by the time for which event collection occurred, amdsmi_counter_value_t.time_running (which is in nanoseconds). To get bytes per second, multiply this value by 10⁹.

Throughput = BEATS/time_running * 10⁹ (bytes/second)

Events in the AMDSMI_EVNT_GRP_XGMI_DATA_OUT group measure the number of beats sent on an XGMI link. Each beat represents 32 bytes. AMDSMI_EVNT_XGMI_DATA_OUT_n represents the number of outbound beats (each representing 32 bytes) on link n.

XGMI throughput can be calculated by multiplying a event such as ::AMDSMI_EVNT_XGMI_DATA_OUT_n by 32 and dividing by the time for which event collection occurred, amdsmi_counter_value_t.time_running (which is in nanoseconds). To get bytes per second, multiply this value by 10⁹.
