72 *
73 * PERF_COUNT_HW_STALLED_CYCLES_BACKEND
74 * PERF_COUNT_HW_STALLED_CYCLES_FRONTEND
75 * The ARC 700 can either measure stalls per pipeline stage, or all stalls
76 * combined; for now we assign all stalls to STALLED_CYCLES_BACKEND
77 * and all pipeline flushes (e.g. caused by mispredicts, etc.) to
78 * STALLED_CYCLES_FRONTEND.
79 *
80 * We could start multiple performance counters and combine everything
81 * afterwards, but that makes it complicated.
82 *
83 * Note that I$ cache misses aren't counted by either of the two!
