186	help
187	  Some versions of the PPC601 (the first PowerPC chip) have bugs which
188	  mean that extra synchronization instructions are required near
189	  certain instructions, typically those that make major changes to the
190	  CPU state.  These extra instructions reduce performance slightly.
191	  If you say N here, these extra instructions will not be included,
192	  resulting in a kernel which will run faster but may not run at all
193	  on some systems with the PPC601 chip.
194
195	  If in doubt, say Y here.
196
197config TAU
198	bool "On-chip CPU temperature sensor support"
199	depends on CLASSIC32
200	help
201	  G3 and G4 processors have an on-chip temperature sensor called the
202	  'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
203	  temperature within 2-4 degrees Celsius. This option shows the current
204	  on-die temperature in /proc/cpuinfo if the cpu supports it.
205
206	  Unfortunately, on some chip revisions, this sensor is very inaccurate
207	  and in many cases, does not work at all, so don't assume the cpu
208	  temp is actually what /proc/cpuinfo says it is.
209
210config TAU_INT
211	bool "Interrupt driven TAU driver (DANGEROUS)"
212	depends on TAU
213	---help---
214	  The TAU supports an interrupt driven mode which causes an interrupt
215	  whenever the temperature goes out of range. This is the fastest way
216	  to get notified the temp has exceeded a range. With this option off,
217	  a timer is used to re-check the temperature periodically.
218
219	  However, on some cpus it appears that the TAU interrupt hardware
220	  is buggy and can cause a situation which would lead unexplained hard
221	  lockups.
222
223	  Unless you are extending the TAU driver, or enjoy kernel/hardware
224	  debugging, leave this option off.
225
226config TAU_AVERAGE
227	bool "Average high and low temp"
228	depends on TAU
229	---help---
230	  The TAU hardware can compare the temperature to an upper and lower
231	  bound.  The default behavior is to show both the upper and lower
232	  bound in /proc/cpuinfo. If the range is large, the temperature is
233	  either changing a lot, or the TAU hardware is broken (likely on some
234	  G4's). If the range is small (around 4 degrees), the temperature is
235	  relatively stable.  If you say Y here, a single temperature value,
236	  halfway between the upper and lower bounds, will be reported in
237	  /proc/cpuinfo.
238
239	  If in doubt, say N here.

245	help
246	  The QUICC Engine (QE) is a new generation of communications
247	  coprocessors on Freescale embedded CPUs (akin to CPM in older chips).
248	  Selecting this option means that you wish to build a kernel
249	  for a machine with a QE coprocessor.

256	select PPC_PCI_CHOICE
257	help
258	  The CPM2 (Communications Processor Module) is a coprocessor on
259	  embedded CPUs made by Freescale.  Selecting this option means that
260	  you wish to build a kernel for a machine with a CPM2 coprocessor
261	  on it (826x, 827x, 8560).
