| 287 | Select this option to enable more accurate task and CPU time |
| 288 | accounting. This is done by reading a CPU counter on each |
| 289 | kernel entry and exit and on transitions within the kernel |
| 290 | between system, softirq and hardirq state, so there is a |
| 291 | small performance impact. This also enables accounting of |
| 292 | stolen time on logically-partitioned systems running on |
| 293 | IBM POWER5-based machines. |
| 294 | |
| 295 | If in doubt, say Y here. |

| 309 | ---help--- |
| 310 | This enables support for systems with more than one CPU. If you have |
| 311 | a system with only one CPU, say N. If you have a system with more |
| 312 | than one CPU, say Y. Note that the kernel does not currently |
| 313 | support SMP machines with 603/603e/603ev or PPC750 ("G3") processors |
| 314 | since they have inadequate hardware support for multiprocessor |
| 315 | operation. |
| 316 | |
| 317 | If you say N here, the kernel will run on single and multiprocessor |
| 318 | machines, but will use only one CPU of a multiprocessor machine. If |
| 319 | you say Y here, the kernel will run on single-processor machines. |
| 320 | On a single-processor machine, the kernel will run faster if you say |
| 321 | N here. |
| 322 | |
| 323 | If you don't know what to do here, say N. |
