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