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

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

 242         depends on TAU
 243         ---help---
 244           The TAU supports an interrupt driven mode which causes an interrupt
 245           whenever the temperature goes out of range. This is the fastest way
 246           to get notified the temp has exceeded a range. With this option off,
 247           a timer is used to re-check the temperature periodically.
 248
 249           However, on some cpus it appears that the TAU interrupt hardware
 250           is buggy and can cause a situation which would lead unexplained hard
 251           lockups.
 252
 253           Unless you are extending the TAU driver, or enjoy kernel/hardware
 254           debugging, leave this option off.

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