196 Some versions of the PPC601 (the first PowerPC chip) have bugs which
197 mean that extra synchronization instructions are required near
198 certain instructions, typically those that make major changes to the
199 CPU state. These extra instructions reduce performance slightly.
200 If you say N here, these extra instructions will not be included,
201 resulting in a kernel which will run faster but may not run at all

Kumar Gala4330f5d2007-03-16 09:32:17 -0500209 help
210 G3 and G4 processors have an on-chip temperature sensor called the
211 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
212 temperature within 2-4 degrees Celsius. This option shows the current
213 on-die temperature in /proc/cpuinfo if the cpu supports it.
214
215 Unfortunately, on some chip revisions, this sensor is very inaccurate
216 and in many cases, does not work at all, so don't assume the cpu
217 temp is actually what /proc/cpuinfo says it is.
218
219config TAU_INT

222 ---help---
223 The TAU supports an interrupt driven mode which causes an interrupt
224 whenever the temperature goes out of range. This is the fastest way
225 to get notified the temp has exceeded a range. With this option off,
226 a timer is used to re-check the temperature periodically.
227
228 However, on some cpus it appears that the TAU interrupt hardware
229 is buggy and can cause a situation which would lead unexplained hard
230 lockups.
231
232 Unless you are extending the TAU driver, or enjoy kernel/hardware
233 debugging, leave this option off.
234
235config TAU_AVERAGE
236 bool "Average high and low temp"
237 depends on TAU
238 ---help---
239 The TAU hardware can compare the temperature to an upper and lower
240 bound. The default behavior is to show both the upper and lower
241 bound in /proc/cpuinfo. If the range is large, the temperature is
242 either changing a lot, or the TAU hardware is broken (likely on some
243 G4's). If the range is small (around 4 degrees), the temperature is
244 relatively stable. If you say Y here, a single temperature value,
245 halfway between the upper and lower bounds, will be reported in
246 /proc/cpuinfo.
247
248 If in doubt, say N here.
