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

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

 213         bool "Interrupt driven TAU driver (DANGEROUS)"
 214         depends on TAU
 215         ---help---
 216           The TAU supports an interrupt driven mode which causes an interrupt
 217           whenever the temperature goes out of range. This is the fastest way
 218           to get notified the temp has exceeded a range. With this option off,
 219           a timer is used to re-check the temperature periodically.
 220
 221           However, on some cpus it appears that the TAU interrupt hardware
 222           is buggy and can cause a situation which would lead unexplained hard
 223           lockups.
 224
 225           Unless you are extending the TAU driver, or enjoy kernel/hardware
 226           debugging, leave this option off.
 227
 228 config TAU_AVERAGE
 229         bool "Average high and low temp"
 230         depends on TAU
 231         ---help---
 232           The TAU hardware can compare the temperature to an upper and lower
 233           bound.  The default behavior is to show both the upper and lower
 234           bound in /proc/cpuinfo. If the range is large, the temperature is
 235           either changing a lot, or the TAU hardware is broken (likely on some
 236           G4's). If the range is small (around 4 degrees), the temperature is
 237           relatively stable.  If you say Y here, a single temperature value,
 238           halfway between the upper and lower bounds, will be reported in
 239           /proc/cpuinfo.
