Type:u64
Parameter:
| Type | Parameter | Name |

| struct trace_buffer * | buf | |
| int | cpu |
| 611 | If Not buffer Then Return race_clock_local(): the simplest and least coherent tracing clock.* Useful for tracing that does not cross to other CPUs nor* does it go through idle events. |

| 615 | ring_buffer_normalize_time_stamp(buffer, cpu, & ts) |
| 617 | Return ts |
