32 The QUICC Engine (QE) is a new generation of communications
33 coprocessors on Freescale embedded CPUs (akin to CPM in older chips).
34 Selecting this option means that you wish to build a kernel

165 bool "Workarounds for PPC601 bugs"
166 depends on 6xx && (PPC_PREP || PPC_PMAC)
167 help
168 Some versions of the PPC601 (the first PowerPC chip) have bugs which
169 mean that extra synchronization instructions are required near
170 certain instructions, typically those that make major changes to the
171 CPU state. These extra instructions reduce performance slightly.
172 If you say N here, these extra instructions will not be included,
173 resulting in a kernel which will run faster but may not run at all
174 on some systems with the PPC601 chip.
175
176 If in doubt, say Y here.

179 bool "On-chip CPU temperature sensor support"
Kumar Gala164a4602007-04-12 15:35:50 -0500180 depends on CLASSIC32
Kumar Gala4330f5d2007-03-16 09:32:17 -0500181 help
182 G3 and G4 processors have an on-chip temperature sensor called the
183 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
184 temperature within 2-4 degrees Celsius. This option shows the current
185 on-die temperature in /proc/cpuinfo if the cpu supports it.
186
187 Unfortunately, on some chip revisions, this sensor is very inaccurate
188 and in many cases, does not work at all, so don't assume the cpu
189 temp is actually what /proc/cpuinfo says it is.

191config TAU_INT
192 bool "Interrupt driven TAU driver (DANGEROUS)"
193 depends on TAU
194 ---help---
195 The TAU supports an interrupt driven mode which causes an interrupt
196 whenever the temperature goes out of range. This is the fastest way
197 to get notified the temp has exceeded a range. With this option off,
198 a timer is used to re-check the temperature periodically.
199
200 However, on some cpus it appears that the TAU interrupt hardware
201 is buggy and can cause a situation which would lead unexplained hard
202 lockups.
203
204 Unless you are extending the TAU driver, or enjoy kernel/hardware
205 debugging, leave this option off.
206
207config TAU_AVERAGE
208 bool "Average high and low temp"
209 depends on TAU
210 ---help---
211 The TAU hardware can compare the temperature to an upper and lower
212 bound. The default behavior is to show both the upper and lower
213 bound in /proc/cpuinfo. If the range is large, the temperature is
214 either changing a lot, or the TAU hardware is broken (likely on some
215 G4's). If the range is small (around 4 degrees), the temperature is
216 relatively stable. If you say Y here, a single temperature value,
217 halfway between the upper and lower bounds, will be reported in
218 /proc/cpuinfo.
219
220 If in doubt, say N here.
