| 477 | help |
| 478 | G3 and G4 processors have an on-chip temperature sensor called the |

| 480 | temperature within 2-4 degrees Celsius. This option shows the current |
| 481 | on-die temperature in /proc/cpuinfo if the cpu supports it. |
| 482 | |
| 483 | Unfortunately, on some chip revisions, this sensor is very inaccurate |
| 484 | and in some cases, does not work at all, so don't assume the cpu |
| 485 | temp is actually what /proc/cpuinfo says it is. |

| 491 | The TAU supports an interrupt driven mode which causes an interrupt |
| 492 | whenever the temperature goes out of range. This is the fastest way |

| 494 | a timer is used to re-check the temperature periodically. |
| 495 | |
| 496 | However, on some cpus it appears that the TAU interrupt hardware |
| 497 | is buggy and can cause a situation which would lead unexplained hard |
| 498 | lockups. |

| 511 | G4's). If the range is small (around 4 degrees), the temperature is |
| 512 | relatively stable. If you say Y here, a single temperature value, |
| 513 | halfway between the upper and lower bounds, will be reported in |
