  143. help
  144. Some versions of the PPC601 (the first PowerPC chip) have bugs which
  145. mean that extra synchronization instructions are required near
  146. certain instructions, typically those that make major changes to the
  147. CPU state. These extra instructions reduce performance slightly.
  148. If you say N here, these extra instructions will not be included,
  149. resulting in a kernel which will run faster but may not run at all
  150. on some systems with the PPC601 chip.
  151. If in doubt, say Y here.
  152. config TAU
  153. bool "On-chip CPU temperature sensor support"
  154. depends on CLASSIC32
  155. help
  156. G3 and G4 processors have an on-chip temperature sensor called the
  157. 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
  158. temperature within 2-4 degrees Celsius. This option shows the current
  159. on-die temperature in /proc/cpuinfo if the cpu supports it.
  160. Unfortunately, on some chip revisions, this sensor is very inaccurate
  161. and in many cases, does not work at all, so don't assume the cpu
  162. temp is actually what /proc/cpuinfo says it is.
  163. config TAU_INT
  164. bool "Interrupt driven TAU driver (DANGEROUS)"
  165. depends on TAU
  166. ---help---
  167. The TAU supports an interrupt driven mode which causes an interrupt
  168. whenever the temperature goes out of range. This is the fastest way
  169. to get notified the temp has exceeded a range. With this option off,
  170. a timer is used to re-check the temperature periodically.
  171. However, on some cpus it appears that the TAU interrupt hardware
  172. is buggy and can cause a situation which would lead unexplained hard
  173. lockups.
  174. Unless you are extending the TAU driver, or enjoy kernel/hardware
  175. debugging, leave this option off.
  176. config TAU_AVERAGE
  177. bool "Average high and low temp"
  178. depends on TAU
  179. ---help---
  180. The TAU hardware can compare the temperature to an upper and lower
  181. bound. The default behavior is to show both the upper and lower
  182. bound in /proc/cpuinfo. If the range is large, the temperature is
  183. either changing a lot, or the TAU hardware is broken (likely on some
  184. G4's). If the range is small (around 4 degrees), the temperature is
  185. relatively stable. If you say Y here, a single temperature value,
  186. halfway between the upper and lower bounds, will be reported in
  187. /proc/cpuinfo.
  188. If in doubt, say N here.
