185 | depends on 6xx && (PPC_PREP || PPC_PMAC) | |
186 | help | |
187 | Some versions of the PPC601 (the first PowerPC chip) have bugs which | |
188 | mean that extra synchronization instructions are required near | |
189 | certain instructions, typically those that make major changes to the | |
190 | CPU state. These extra instructions reduce performance slightly. | |
191 | If you say N here, these extra instructions will not be included, | |
192 | resulting in a kernel which will run faster but may not run at all | |
193 | on some systems with the PPC601 chip. | |

198 | bool "On-chip CPU temperature sensor support" | |
164a460d | 199 | depends on CLASSIC32 |
4330f5da KG |
200 | help |
201 | G3 and G4 processors have an on-chip temperature sensor called the | |
202 | 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die | |
203 | temperature within 2-4 degrees Celsius. This option shows the current | |
204 | on-die temperature in /proc/cpuinfo if the cpu supports it. | |
205 | ||
206 | Unfortunately, on some chip revisions, this sensor is very inaccurate | |
207 | and in many cases, does not work at all, so don't assume the cpu | |
208 | temp is actually what /proc/cpuinfo says it is. | |
209 | ||
210 | config TAU_INT | |
211 | bool "Interrupt driven TAU driver (DANGEROUS)" | |
212 | depends on TAU | |
213 | ---help--- | |
214 | The TAU supports an interrupt driven mode which causes an interrupt | |
215 | whenever the temperature goes out of range. This is the fastest way | |
216 | to get notified the temp has exceeded a range. With this option off, | |
217 | a timer is used to re-check the temperature periodically. | |
218 | ||
219 | However, on some cpus it appears that the TAU interrupt hardware | |
220 | is buggy and can cause a situation which would lead unexplained hard | |
221 | lockups. | |
222 | ||
223 | Unless you are extending the TAU driver, or enjoy kernel/hardware | |
224 | debugging, leave this option off. | |

226 | config TAU_AVERAGE | |
227 | bool "Average high and low temp" | |

229 | ---help--- | |
230 | The TAU hardware can compare the temperature to an upper and lower | |
231 | bound. The default behavior is to show both the upper and lower | |
232 | bound in /proc/cpuinfo. If the range is large, the temperature is | |
233 | either changing a lot, or the TAU hardware is broken (likely on some | |
234 | G4's). If the range is small (around 4 degrees), the temperature is | |
235 | relatively stable. If you say Y here, a single temperature value, | |
236 | halfway between the upper and lower bounds, will be reported in | |
237 | /proc/cpuinfo. | |

239 | If in doubt, say N here. | |
