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

Kumar Gala4330f5d2007-03-16 09:32:17 -0500199 help
200 G3 and G4 processors have an on-chip temperature sensor called the
201 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
202 temperature within 2-4 degrees Celsius. This option shows the current
203 on-die temperature in /proc/cpuinfo if the cpu supports it.
204
205 Unfortunately, on some chip revisions, this sensor is very inaccurate
206 and in many cases, does not work at all, so don't assume the cpu
207 temp is actually what /proc/cpuinfo says it is.
208
209config TAU_INT

212 ---help---
213 The TAU supports an interrupt driven mode which causes an interrupt
214 whenever the temperature goes out of range. This is the fastest way
215 to get notified the temp has exceeded a range. With this option off,
216 a timer is used to re-check the temperature periodically.
217
218 However, on some cpus it appears that the TAU interrupt hardware
219 is buggy and can cause a situation which would lead unexplained hard
220 lockups.
221
222 Unless you are extending the TAU driver, or enjoy kernel/hardware
223 debugging, leave this option off.
224
225config TAU_AVERAGE
226 bool "Average high and low temp"
227 depends on TAU
228 ---help---
229 The TAU hardware can compare the temperature to an upper and lower
230 bound. The default behavior is to show both the upper and lower
231 bound in /proc/cpuinfo. If the range is large, the temperature is
232 either changing a lot, or the TAU hardware is broken (likely on some
233 G4's). If the range is small (around 4 degrees), the temperature is
234 relatively stable. If you say Y here, a single temperature value,
235 halfway between the upper and lower bounds, will be reported in
236 /proc/cpuinfo.
237
238 If in doubt, say N here.
