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