40 metric register that reports slots ratios for the different bottleneck
53 metric event, and allow user programs to read the performance counters.
58 The metric events are mapped to the pseudo event event=0x00, umask=0x8X.

124 #define RDPMC_METRIC (1 << 29) /* return metric counters */
158 The binary ratios in the metric value can be converted to float ratios:
162 /* L1 Topdown metric events */
169 * L2 Topdown metric events.
179 The ratios in the metric accumulate for the time when the counter
210 Later the individual ratios of L1 metric events for the measurement period can
225 The individual ratios of L2 metric events for the measurement period can be
226 recreated from L1 and L2 metric counters. (Available on Sapphire Rapids and
296 Four pseudo TopDown metric events are exposed for the end-users,
300 - All the TopDown metric events must be in a group with the SLOTS event.
302 - The PERF_FORMAT_GROUP flag must be applied for each TopDown metric
305 The SLOTS event and the TopDown metric events can be counting members of
315 metrics. Four more TopDown metric events are exposed for the end-users,
320 corresponding level 1 metric in the lower half. Software can deduce the
351 capture retire_latency value of required events(event with :R in metric formula)
352 with perf record. The retire_latency value would be used in metric calculation.
