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.
221
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.
