186 bool "Workarounds for PPC601 bugs"
187 depends on 6xx && (PPC_PREP || PPC_PMAC)
189 Some versions of the PPC601 (the first PowerPC chip) have bugs which
190 mean that extra synchronization instructions are required near
191 certain instructions, typically those that make major changes to the
192 CPU state. These extra instructions reduce performance slightly.
193 If you say N here, these extra instructions will not be included,
194 resulting in a kernel which will run faster but may not run at all
195 on some systems with the PPC601 chip.
197 If in doubt, say Y here.
200 bool "On-chip CPU temperature sensor support"
203 G3 and G4 processors have an on-chip temperature sensor called the
204 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
205 temperature within 2-4 degrees Celsius. This option shows the current
206 on-die temperature in /proc/cpuinfo if the cpu supports it.
208 Unfortunately, on some chip revisions, this sensor is very inaccurate
209 and in many cases, does not work at all, so don't assume the cpu
210 temp is actually what /proc/cpuinfo says it is.
213 bool "Interrupt driven TAU driver (DANGEROUS)"
216 The TAU supports an interrupt driven mode which causes an interrupt
217 whenever the temperature goes out of range. This is the fastest way
218 to get notified the temp has exceeded a range. With this option off,
219 a timer is used to re-check the temperature periodically.
221 However, on some cpus it appears that the TAU interrupt hardware
222 is buggy and can cause a situation which would lead unexplained hard
225 Unless you are extending the TAU driver, or enjoy kernel/hardware
226 debugging, leave this option off.
229 bool "Average high and low temp"
232 The TAU hardware can compare the temperature to an upper and lower
233 bound. The default behavior is to show both the upper and lower
234 bound in /proc/cpuinfo. If the range is large, the temperature is
235 either changing a lot, or the TAU hardware is broken (likely on some
236 G4's). If the range is small (around 4 degrees), the temperature is
237 relatively stable. If you say Y here, a single temperature value,
238 halfway between the upper and lower bounds, will be reported in
241 If in doubt, say N here.
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.
255 The CPM2 (Communications Processor Module) is a coprocessor on
256 embedded CPUs made by Freescale. Selecting this option means that
257 you wish to build a kernel for a machine with a CPM2 coprocessor
258 on it (826x, 827x, 8560).
