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