223 certain instructions, typically those that make major changes to the
224 CPU state. These extra instructions reduce performance slightly.
225 If you say N here, these extra instructions will not be included,

Kumar Gala4330f5d2007-03-16 09:32:17 -0500234 help
235 G3 and G4 processors have an on-chip temperature sensor called the
236 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
237 temperature within 2-4 degrees Celsius. This option shows the current
238 on-die temperature in /proc/cpuinfo if the cpu supports it.
239
240 Unfortunately, on some chip revisions, this sensor is very inaccurate
241 and in many cases, does not work at all, so don't assume the cpu
242 temp is actually what /proc/cpuinfo says it is.
243
244config TAU_INT

248 The TAU supports an interrupt driven mode which causes an interrupt
249 whenever the temperature goes out of range. This is the fastest way
250 to get notified the temp has exceeded a range. With this option off,
251 a timer is used to re-check the temperature periodically.
252
253 However, on some cpus it appears that the TAU interrupt hardware
254 is buggy and can cause a situation which would lead unexplained hard
255 lockups.
256
257 Unless you are extending the TAU driver, or enjoy kernel/hardware
258 debugging, leave this option off.
259
260config TAU_AVERAGE
261 bool "Average high and low temp"

264 The TAU hardware can compare the temperature to an upper and lower
265 bound. The default behavior is to show both the upper and lower
266 bound in /proc/cpuinfo. If the range is large, the temperature is
267 either changing a lot, or the TAU hardware is broken (likely on some
268 G4's). If the range is small (around 4 degrees), the temperature is
269 relatively stable. If you say Y here, a single temperature value,
270 halfway between the upper and lower bounds, will be reported in
271 /proc/cpuinfo.
272
273 If in doubt, say N here.
