|  | 439 | help | 
|  | 440 | G3 and G4 processors have an on-chip temperature sensor called the | 
|  | 441 | 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die | 
|  | 442 | temperature within 2-4 degrees Celsius. This option shows the current | 
|  | 443 | on-die temperature in /proc/cpuinfo if the cpu supports it. | 
|  | 444 |  | 
|  | 445 | Unfortunately, on some chip revisions, this sensor is very inaccurate | 
|  | 446 | and in some cases, does not work at all, so don't assume the cpu | 
|  | 447 | temp is actually what /proc/cpuinfo says it is. |

|  | 453 | The TAU supports an interrupt driven mode which causes an interrupt | 
|  | 454 | whenever the temperature goes out of range. This is the fastest way | 
|  | 455 | to get notified the temp has exceeded a range. With this option off, | 
|  | 456 | a timer is used to re-check the temperature periodically. | 
|  | 457 |  | 
|  | 458 | However, on some cpus it appears that the TAU interrupt hardware | 
|  | 459 | is buggy and can cause a situation which would lead unexplained hard | 
|  | 460 | lockups. | 
|  | 461 |  | 
|  | 462 | Unless you are extending the TAU driver, or enjoy kernel/hardware |

|  | 471 | bound in /proc/cpuinfo. If the range is large, the temperature is | 
|  | 472 | either changing a lot, or the TAU hardware is broken (likely on some | 
|  | 473 | G4's). If the range is small (around 4 degrees), the temperature is | 
|  | 474 | relatively stable.  If you say Y here, a single temperature value, |
