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

160 bool "Workarounds for PPC601 bugs"
161 depends on 6xx && (PPC_PREP || PPC_PMAC)
163 Some versions of the PPC601 (the first PowerPC chip) have bugs which
164 mean that extra synchronization instructions are required near
165 certain instructions, typically those that make major changes to the
166 CPU state. These extra instructions reduce performance slightly.
167 If you say N here, these extra instructions will not be included,
168 resulting in a kernel which will run faster but may not run at all
169 on some systems with the PPC601 chip.
171 If in doubt, say Y here.
174 bool "On-chip CPU temperature sensor support"
177 G3 and G4 processors have an on-chip temperature sensor called the
178 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
179 temperature within 2-4 degrees Celsius. This option shows the current
180 on-die temperature in /proc/cpuinfo if the cpu supports it.
182 Unfortunately, on some chip revisions, this sensor is very inaccurate
183 and in many cases, does not work at all, so don't assume the cpu
184 temp is actually what /proc/cpuinfo says it is.
187 bool "Interrupt driven TAU driver (DANGEROUS)"
190 The TAU supports an interrupt driven mode which causes an interrupt
191 whenever the temperature goes out of range. This is the fastest way
192 to get notified the temp has exceeded a range. With this option off,
193 a timer is used to re-check the temperature periodically.
195 However, on some cpus it appears that the TAU interrupt hardware
196 is buggy and can cause a situation which would lead unexplained hard
199 Unless you are extending the TAU driver, or enjoy kernel/hardware
200 debugging, leave this option off.
203 bool "Average high and low temp"
206 The TAU hardware can compare the temperature to an upper and lower
207 bound. The default behavior is to show both the upper and lower
208 bound in /proc/cpuinfo. If the range is large, the temperature is
209 either changing a lot, or the TAU hardware is broken (likely on some
210 G4's). If the range is small (around 4 degrees), the temperature is
211 relatively stable. If you say Y here, a single temperature value,
212 halfway between the upper and lower bounds, will be reported in
215 If in doubt, say N here.
