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

 216         depends on CLASSIC32
 217         help
 218           G3 and G4 processors have an on-chip temperature sensor called the
 219           'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
 220           temperature within 2-4 degrees Celsius. This option shows the current
 221           on-die temperature in /proc/cpuinfo if the cpu supports it.
 222
 223           Unfortunately, on some chip revisions, this sensor is very inaccurate
 224           and in many cases, does not work at all, so don't assume the cpu
 225           temp is actually what /proc/cpuinfo says it is.

 228         bool "Interrupt driven TAU driver (DANGEROUS)"
 229         depends on TAU
 230         ---help---
 231           The TAU supports an interrupt driven mode which causes an interrupt
 232           whenever the temperature goes out of range. This is the fastest way
 233           to get notified the temp has exceeded a range. With this option off,
 234           a timer is used to re-check the temperature periodically.
 235
 236           However, on some cpus it appears that the TAU interrupt hardware
 237           is buggy and can cause a situation which would lead unexplained hard
 238           lockups.
 239
 240           Unless you are extending the TAU driver, or enjoy kernel/hardware
 241           debugging, leave this option off.
 242

 245         depends on TAU
 246         ---help---
 247           The TAU hardware can compare the temperature to an upper and lower
 248           bound.  The default behavior is to show both the upper and lower
 249           bound in /proc/cpuinfo. If the range is large, the temperature is
 250           either changing a lot, or the TAU hardware is broken (likely on some
 251           G4's). If the range is small (around 4 degrees), the temperature is
 252           relatively stable.  If you say Y here, a single temperature value,
 253           halfway between the upper and lower bounds, will be reported in
 254           /proc/cpuinfo.
