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

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

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

 222         bool "Average high and low temp"
 223         depends on TAU
 224         ---help---
 225           The TAU hardware can compare the temperature to an upper and lower
 226           bound.  The default behavior is to show both the upper and lower
 227           bound in /proc/cpuinfo. If the range is large, the temperature is
 228           either changing a lot, or the TAU hardware is broken (likely on some
 229           G4's). If the range is small (around 4 degrees), the temperature is
 230           relatively stable.  If you say Y here, a single temperature value,
 231           halfway between the upper and lower bounds, will be reported in
 232           /proc/cpuinfo.
