215	help
216	  Some versions of the PPC601 (the first PowerPC chip) have bugs which
217	  mean that extra synchronization instructions are required near
218	  certain instructions, typically those that make major changes to the
219	  CPU state.  These extra instructions reduce performance slightly.
220	  If you say N here, these extra instructions will not be included,
221	  resulting in a kernel which will run faster but may not run at all
222	  on some systems with the PPC601 chip.
223
224	  If in doubt, say Y here.

226config TAU
227	bool "On-chip CPU temperature sensor support"
228	depends on CLASSIC32
229	help
230	  G3 and G4 processors have an on-chip temperature sensor called the
231	  'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
232	  temperature within 2-4 degrees Celsius. This option shows the current
233	  on-die temperature in /proc/cpuinfo if the cpu supports it.
234
235	  Unfortunately, on some chip revisions, this sensor is very inaccurate
236	  and in many cases, does not work at all, so don't assume the cpu
237	  temp is actually what /proc/cpuinfo says it is.
238
239config TAU_INT
240	bool "Interrupt driven TAU driver (DANGEROUS)"
241	depends on TAU
242	---help---
243	  The TAU supports an interrupt driven mode which causes an interrupt
244	  whenever the temperature goes out of range. This is the fastest way
245	  to get notified the temp has exceeded a range. With this option off,
246	  a timer is used to re-check the temperature periodically.
247
248	  However, on some cpus it appears that the TAU interrupt hardware
249	  is buggy and can cause a situation which would lead unexplained hard
250	  lockups.
251
252	  Unless you are extending the TAU driver, or enjoy kernel/hardware
253	  debugging, leave this option off.
254
255config TAU_AVERAGE
256	bool "Average high and low temp"
257	depends on TAU
258	---help---
259	  The TAU hardware can compare the temperature to an upper and lower
260	  bound.  The default behavior is to show both the upper and lower
261	  bound in /proc/cpuinfo. If the range is large, the temperature is
262	  either changing a lot, or the TAU hardware is broken (likely on some
263	  G4's). If the range is small (around 4 degrees), the temperature is
264	  relatively stable.  If you say Y here, a single temperature value,
265	  halfway between the upper and lower bounds, will be reported in
266	  /proc/cpuinfo.
267
268	  If in doubt, say N here.

286	  The CPM2 (Communications Processor Module) is a coprocessor on
287	  embedded CPUs made by Freescale.  Selecting this option means that
288	  you wish to build a kernel for a machine with a CPM2 coprocessor
289	  on it (826x, 827x, 8560).
