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

  187. config TAU
  188. bool "On-chip CPU temperature sensor support"

  190. help
  191. G3 and G4 processors have an on-chip temperature sensor called the
  192. 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
  193. temperature within 2-4 degrees Celsius. This option shows the current
  194. on-die temperature in /proc/cpuinfo if the cpu supports it.
  195. Unfortunately, on some chip revisions, this sensor is very inaccurate
  196. and in many cases, does not work at all, so don't assume the cpu
  197. temp is actually what /proc/cpuinfo says it is.
  198. config TAU_INT
  199. bool "Interrupt driven TAU driver (DANGEROUS)"
  200. depends on TAU
  201. ---help---
  202. The TAU supports an interrupt driven mode which causes an interrupt
  203. whenever the temperature goes out of range. This is the fastest way
  204. to get notified the temp has exceeded a range. With this option off,
  205. a timer is used to re-check the temperature periodically.
  206. However, on some cpus it appears that the TAU interrupt hardware
  207. is buggy and can cause a situation which would lead unexplained hard
  208. lockups.
  209. Unless you are extending the TAU driver, or enjoy kernel/hardware
  210. debugging, leave this option off.
  211. config TAU_AVERAGE
  212. bool "Average high and low temp"
  213. depends on TAU
  214. ---help---
  215. The TAU hardware can compare the temperature to an upper and lower
  216. bound. The default behavior is to show both the upper and lower
  217. bound in /proc/cpuinfo. If the range is large, the temperature is
  218. either changing a lot, or the TAU hardware is broken (likely on some
  219. G4's). If the range is small (around 4 degrees), the temperature is
  220. relatively stable. If you say Y here, a single temperature value,
  221. halfway between the upper and lower bounds, will be reported in
  222. /proc/cpuinfo.
  223. If in doubt, say N here.
