| 18 | .Sh DESCRIPTION | |
| 19 | A | |
| 20 | .Tn KL-11 | |
| 21 | or | |
| 22 | .Tn DL-11W | |
| 23 | can be used as an alternate real | |
| 604e52c8 KM |
24 | time clock |
| 25 | source. When configured, certain system | |
| 26 | statistics and, optionally, system profiling work | |
| 27 | will be collected each time the clock interrupts. For | |
| 9903e566 CL |
28 | optimum accuracy in profiling, the |
| 29 | .Tn DL-11W | |
| 30 | should be | |
| 604e52c8 KM |
31 | configured to interrupt at the highest possible priority |
| 32 | level. The | |
| 9903e566 | 33 | .Nm kg |
| 604e52c8 KM |
34 | device driver automatically calibrates itself to the |
| 35 | line clock frequency. | |
