| 18 | </ul> | |

| 21 | <tt> | |
| 22 | <ul> | |
| 23 | pdisable [<i>cpu-mask</i>]<br> | |
| 24 | pdisable -cpu <i>cpu_set</i> | |
| 25 | <p> | |
| 26 | penable [<i>cpu-mask</i>]<br> | |
| 27 | penable -cpu <i>cpu_set</i> | |

| 31 | <h4>DESCRIPTION</h4> | |
| 32 | <ul> | |
| 33 | penable enables a collection of cpus for execution. This collection | |
| 34 | is a set of cpus, specified through either the <a | |
| 35 | href="flag_cpu.html">-cpu</a> flag or, alternatively | |
| 36 | <i>cpu-mask</i>, which is a bitmask corresponding to cpus | |
| 37 | numbered 63 through 0, most significant bit to least. | |
| 38 | <p> | |
| 39 | If no argument is given, penable will list all enabled strands. | |
| 40 | <p> | |
| 41 | pdisable disables a collection of cpus. This collection is specified | |
| 42 | using the <a href="flag_cpu.html">-cpu</a> or a cpu mask as with penable. | |
| 43 | A disabled strand is simply stalled for an infinite | |
| 44 | amount of time. | |
| 45 | Take care that least one cpu is enabled to guarantee forward progress. | |
| 46 | <p> | |
| 47 | If no argument is given, pdisable will list all disabled strands. | |
| 48 | </ul> | |
