Lines Matching full:slots

49 On Ice Lake, there is a new fixed counter 3: SLOTS, which reports
50 "pipeline SLOTS" (cycles multiplied by core issue width) and a
51 metric register that reports slots ratios for the different bottleneck
63 The application opens a group with fixed counter 3 (SLOTS) and any
86 /* Open slots counter file descriptor for current task. */
87 struct perf_event_attr slots = {
94 int slots_fd = perf_event_open(&slots, 0, -1, -1, 0);
100  * Set slots event as the leader of the group.
115 to read slots and the topdown metrics at different points of the program:
166 This can be done by scaling the metrics with the slots counter
169 Then it's possible to take deltas of these slots counts
241 - All the TopDown metric events must be in a group with the SLOTS event.
242 - The SLOTS event must be the leader of the group.
246 The SLOTS event and the TopDown metric events can be counting members of
247 a sampling read group. Since the SLOTS event must be the leader of a TopDown
249 For example, perf record -e '{slots, $sampling_event, topdown-retiring}:S'
