 215           Some versions of the PPC601 (the first PowerPC chip) have bugs which

 217           certain instructions, typically those that make major changes to the
 218           CPU state.  These extra instructions reduce performance slightly.
 219           If you say N here, these extra instructions will not be included,
 220           resulting in a kernel which will run faster but may not run at all
 221           on some systems with the PPC601 chip.

 227         depends on CLASSIC32
 228         help
 229           G3 and G4 processors have an on-chip temperature sensor called the
 230           'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
 231           temperature within 2-4 degrees Celsius. This option shows the current
 232           on-die temperature in /proc/cpuinfo if the cpu supports it.
 233
 234           Unfortunately, on some chip revisions, this sensor is very inaccurate
 235           and in many cases, does not work at all, so don't assume the cpu
 236           temp is actually what /proc/cpuinfo says it is.

 240         depends on TAU
 241         ---help---
 242           The TAU supports an interrupt driven mode which causes an interrupt
 243           whenever the temperature goes out of range. This is the fastest way
 244           to get notified the temp has exceeded a range. With this option off,
 245           a timer is used to re-check the temperature periodically.
 246
 247           However, on some cpus it appears that the TAU interrupt hardware
 248           is buggy and can cause a situation which would lead unexplained hard
 249           lockups.
 250

 252           debugging, leave this option off.

 257         ---help---
 258           The TAU hardware can compare the temperature to an upper and lower
 259           bound.  The default behavior is to show both the upper and lower
 260           bound in /proc/cpuinfo. If the range is large, the temperature is
 261           either changing a lot, or the TAU hardware is broken (likely on some
 262           G4's). If the range is small (around 4 degrees), the temperature is
 263           relatively stable.  If you say Y here, a single temperature value,
 264           halfway between the upper and lower bounds, will be reported in
 265           /proc/cpuinfo.
