179 bool "Workarounds for PPC601 bugs"
180 depends on 6xx && (PPC_PREP || PPC_PMAC)
182 Some versions of the PPC601 (the first PowerPC chip) have bugs which
183 mean that extra synchronization instructions are required near
184 certain instructions, typically those that make major changes to the
185 CPU state. These extra instructions reduce performance slightly.
186 If you say N here, these extra instructions will not be included,
187 resulting in a kernel which will run faster but may not run at all
188 on some systems with the PPC601 chip.
190 If in doubt, say Y here.
193 bool "On-chip CPU temperature sensor support"
196 G3 and G4 processors have an on-chip temperature sensor called the
197 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
198 temperature within 2-4 degrees Celsius. This option shows the current
199 on-die temperature in /proc/cpuinfo if the cpu supports it.
201 Unfortunately, on some chip revisions, this sensor is very inaccurate
202 and in many cases, does not work at all, so don't assume the cpu
203 temp is actually what /proc/cpuinfo says it is.
206 bool "Interrupt driven TAU driver (DANGEROUS)"
209 The TAU supports an interrupt driven mode which causes an interrupt
210 whenever the temperature goes out of range. This is the fastest way
211 to get notified the temp has exceeded a range. With this option off,
212 a timer is used to re-check the temperature periodically.
214 However, on some cpus it appears that the TAU interrupt hardware
215 is buggy and can cause a situation which would lead unexplained hard
218 Unless you are extending the TAU driver, or enjoy kernel/hardware
219 debugging, leave this option off.
222 bool "Average high and low temp"
225 The TAU hardware can compare the temperature to an upper and lower
226 bound. The default behavior is to show both the upper and lower
227 bound in /proc/cpuinfo. If the range is large, the temperature is
228 either changing a lot, or the TAU hardware is broken (likely on some
229 G4's). If the range is small (around 4 degrees), the temperature is
230 relatively stable. If you say Y here, a single temperature value,
231 halfway between the upper and lower bounds, will be reported in
234 If in doubt, say N here.
239 The QUICC Engine (QE) is a new generation of communications
240 coprocessors on Freescale embedded CPUs (akin to CPM in older chips).
241 Selecting this option means that you wish to build a kernel
242 for a machine with a QE coprocessor.
248 The CPM2 (Communications Processor Module) is a coprocessor on
249 embedded CPUs made by Freescale. Selecting this option means that
250 you wish to build a kernel for a machine with a CPM2 coprocessor
251 on it (826x, 827x, 8560).
