  168. help
  169. Some versions of the PPC601 (the first PowerPC chip) have bugs which
  170. mean that extra synchronization instructions are required near
  171. certain instructions, typically those that make major changes to the
  172. CPU state. These extra instructions reduce performance slightly.
  173. If you say N here, these extra instructions will not be included,
  174. resulting in a kernel which will run faster but may not run at all
  175. on some systems with the PPC601 chip.
  176. If in doubt, say Y here.
  177. config TAU

  179. depends on CLASSIC32
  180. help
  181. G3 and G4 processors have an on-chip temperature sensor called the
  182. 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
  183. temperature within 2-4 degrees Celsius. This option shows the current
  184. on-die temperature in /proc/cpuinfo if the cpu supports it.
  185. Unfortunately, on some chip revisions, this sensor is very inaccurate
  186. and in many cases, does not work at all, so don't assume the cpu
  187. temp is actually what /proc/cpuinfo says it is.
  188. config TAU_INT
  189. bool "Interrupt driven TAU driver (DANGEROUS)"
  190. depends on TAU
  191. ---help---
  192. The TAU supports an interrupt driven mode which causes an interrupt
  193. whenever the temperature goes out of range. This is the fastest way
  194. to get notified the temp has exceeded a range. With this option off,
  195. a timer is used to re-check the temperature periodically.
  196. However, on some cpus it appears that the TAU interrupt hardware
  197. is buggy and can cause a situation which would lead unexplained hard
  198. lockups.
  199. Unless you are extending the TAU driver, or enjoy kernel/hardware
  200. debugging, leave this option off.
  201. config TAU_AVERAGE
  202. bool "Average high and low temp"
  203. depends on TAU
  204. ---help---
  205. The TAU hardware can compare the temperature to an upper and lower
  206. bound. The default behavior is to show both the upper and lower
  207. bound in /proc/cpuinfo. If the range is large, the temperature is
  208. either changing a lot, or the TAU hardware is broken (likely on some
  209. G4's). If the range is small (around 4 degrees), the temperature is
  210. relatively stable. If you say Y here, a single temperature value,
  211. halfway between the upper and lower bounds, will be reported in
  212. /proc/cpuinfo.
  213. If in doubt, say N here.
