Name:XXX PERF_SAMPLE_READ vs inherited events seems difficult.* The problem is that its both hard and excessively expensive to iterate the* child list, not to mention that its impossible to IPI the children running* on another CPU, from interrupt/NMI context.
Proto:static void perf_output_read(struct perf_output_handle *handle, struct perf_event *event)
Type:void
Parameter:
Type | Parameter | Name |
---|---|---|
struct perf_output_handle * | handle | |
struct perf_event * | event |
6538 | read_format = read_format |
6549 | If read_format & PERF_FORMAT_TOTAL_TIMES Then calc_timer_values(event, & now, & enabled, & running) |
6552 | If read_format & PERF_FORMAT_GROUP Then perf_output_read_group(handle, event, enabled, running) |
6554 | Else perf_output_read_one(handle, event, enabled, running) |
