 187           Some versions of the PPC601 (the first PowerPC chip) have bugs which
 188           mean that extra synchronization instructions are required near
 189           certain instructions, typically those that make major changes to the
 190           CPU state.  These extra instructions reduce performance slightly.
 191           If you say N here, these extra instructions will not be included,
 192           resulting in a kernel which will run faster but may not run at all
 193           on some systems with the PPC601 chip.

 199         depends on CLASSIC32
 200         help
 201           G3 and G4 processors have an on-chip temperature sensor called the
 202           'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
 203           temperature within 2-4 degrees Celsius. This option shows the current
 204           on-die temperature in /proc/cpuinfo if the cpu supports it.
 205
 206           Unfortunately, on some chip revisions, this sensor is very inaccurate
 207           and in many cases, does not work at all, so don't assume the cpu
 208           temp is actually what /proc/cpuinfo says it is.

 211         bool "Interrupt driven TAU driver (DANGEROUS)"
 212         depends on TAU
 213         ---help---
 214           The TAU supports an interrupt driven mode which causes an interrupt
 215           whenever the temperature goes out of range. This is the fastest way
 216           to get notified the temp has exceeded a range. With this option off,
 217           a timer is used to re-check the temperature periodically.
 218
 219           However, on some cpus it appears that the TAU interrupt hardware
 220           is buggy and can cause a situation which would lead unexplained hard
 221           lockups.
 222
 223           Unless you are extending the TAU driver, or enjoy kernel/hardware
 224           debugging, leave this option off.

 229         ---help---
 230           The TAU hardware can compare the temperature to an upper and lower
 231           bound.  The default behavior is to show both the upper and lower
 232           bound in /proc/cpuinfo. If the range is large, the temperature is
 233           either changing a lot, or the TAU hardware is broken (likely on some
 234           G4's). If the range is small (around 4 degrees), the temperature is
 235           relatively stable.  If you say Y here, a single temperature value,
 236           halfway between the upper and lower bounds, will be reported in
 237           /proc/cpuinfo.
