Kumar Gala4330f5d2007-03-16 09:32:17 -0500251 help
252 G3 and G4 processors have an on-chip temperature sensor called the
253 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
254 temperature within 2-4 degrees Celsius. This option shows the current
255 on-die temperature in /proc/cpuinfo if the cpu supports it.
256
257 Unfortunately, on some chip revisions, this sensor is very inaccurate
258 and in many cases, does not work at all, so don't assume the cpu
259 temp is actually what /proc/cpuinfo says it is.

261config TAU_INT

264 ---help---
265 The TAU supports an interrupt driven mode which causes an interrupt
266 whenever the temperature goes out of range. This is the fastest way
267 to get notified the temp has exceeded a range. With this option off,
268 a timer is used to re-check the temperature periodically.
269
270 However, on some cpus it appears that the TAU interrupt hardware
271 is buggy and can cause a situation which would lead unexplained hard
272 lockups.
273
274 Unless you are extending the TAU driver, or enjoy kernel/hardware
275 debugging, leave this option off.
276
277config TAU_AVERAGE

281 The TAU hardware can compare the temperature to an upper and lower

283 bound in /proc/cpuinfo. If the range is large, the temperature is
284 either changing a lot, or the TAU hardware is broken (likely on some
285 G4's). If the range is small (around 4 degrees), the temperature is
286 relatively stable. If you say Y here, a single temperature value,
287 halfway between the upper and lower bounds, will be reported in
288 /proc/cpuinfo.
289
290 If in doubt, say N here.
