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