 238           Some versions of the PPC601 (the first PowerPC chip) have bugs which
 239           mean that extra synchronization instructions are required near
 240           certain instructions, typically those that make major changes to the
 241           CPU state.  These extra instructions reduce performance slightly.
 242           If you say N here, these extra instructions will not be included,
 243           resulting in a kernel which will run faster but may not run at all

 252           G3 and G4 processors have an on-chip temperature sensor called the
 253           'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
 254           temperature within 2-4 degrees Celsius. This option shows the current
 255           on-die temperature in /proc/cpuinfo if the cpu supports it.
 256
 257           Unfortunately, on some chip revisions, this sensor is very inaccurate
 258           and in many cases, does not work at all, so don't assume the cpu
 259           temp is actually what /proc/cpuinfo says it is.

 264         ---help---
 265           The TAU supports an interrupt driven mode which causes an interrupt
 266           whenever the temperature goes out of range. This is the fastest way
 267           to get notified the temp has exceeded a range. With this option off,
 268           a timer is used to re-check the temperature periodically.
 269
 270           However, on some cpus it appears that the TAU interrupt hardware
 271           is buggy and can cause a situation which would lead unexplained hard
 272           lockups.

 280         ---help---
 281           The TAU hardware can compare the temperature to an upper and lower
 282           bound.  The default behavior is to show both the upper and lower
 283           bound in /proc/cpuinfo. If the range is large, the temperature is
 284           either changing a lot, or the TAU hardware is broken (likely on some
 285           G4's). If the range is small (around 4 degrees), the temperature is
 286           relatively stable.  If you say Y here, a single temperature value,
 287           halfway between the upper and lower bounds, will be reported in
