213 help
214 Some versions of the PPC601 (the first PowerPC chip) have bugs which
215 mean that extra synchronization instructions are required near
216 certain instructions, typically those that make major changes to the
217 CPU state. These extra instructions reduce performance slightly.
218 If you say N here, these extra instructions will not be included,
219 resulting in a kernel which will run faster but may not run at all
220 on some systems with the PPC601 chip.

222 If in doubt, say Y here.

224config TAU
225 bool "On-chip CPU temperature sensor support"
226 depends on CLASSIC32
227 help
228 G3 and G4 processors have an on-chip temperature sensor called the
229 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
230 temperature within 2-4 degrees Celsius. This option shows the current
231 on-die temperature in /proc/cpuinfo if the cpu supports it.
232
233 Unfortunately, on some chip revisions, this sensor is very inaccurate
234 and in many cases, does not work at all, so don't assume the cpu
235 temp is actually what /proc/cpuinfo says it is.
236
237config TAU_INT
238 bool "Interrupt driven TAU driver (DANGEROUS)"
239 depends on TAU
240 ---help---
241 The TAU supports an interrupt driven mode which causes an interrupt
242 whenever the temperature goes out of range. This is the fastest way
243 to get notified the temp has exceeded a range. With this option off,
244 a timer is used to re-check the temperature periodically.
245
246 However, on some cpus it appears that the TAU interrupt hardware
247 is buggy and can cause a situation which would lead unexplained hard
248 lockups.
249
250 Unless you are extending the TAU driver, or enjoy kernel/hardware
251 debugging, leave this option off.
252
253config TAU_AVERAGE
254 bool "Average high and low temp"
255 depends on TAU
256 ---help---
257 The TAU hardware can compare the temperature to an upper and lower
258 bound. The default behavior is to show both the upper and lower
259 bound in /proc/cpuinfo. If the range is large, the temperature is
260 either changing a lot, or the TAU hardware is broken (likely on some
261 G4's). If the range is small (around 4 degrees), the temperature is
262 relatively stable. If you say Y here, a single temperature value,
263 halfway between the upper and lower bounds, will be reported in
264 /proc/cpuinfo.
265
266 If in doubt, say N here.
