35 | Selecting this option means that you wish to build a kernel | |

170 | bool "Workarounds for PPC601 bugs" | |
171 | depends on 6xx && (PPC_PREP || PPC_PMAC) | |
172 | help | |
173 | Some versions of the PPC601 (the first PowerPC chip) have bugs which | |
174 | mean that extra synchronization instructions are required near | |
175 | certain instructions, typically those that make major changes to the | |
176 | CPU state. These extra instructions reduce performance slightly. | |
177 | If you say N here, these extra instructions will not be included, | |
178 | resulting in a kernel which will run faster but may not run at all | |
179 | on some systems with the PPC601 chip. | |
180 | ||
181 | If in doubt, say Y here. | |

184 | bool "On-chip CPU temperature sensor support" | |
164a460d | 185 | depends on CLASSIC32 |
4330f5da KG |
186 | help |
187 | G3 and G4 processors have an on-chip temperature sensor called the | |
188 | 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die | |
189 | temperature within 2-4 degrees Celsius. This option shows the current | |
190 | on-die temperature in /proc/cpuinfo if the cpu supports it. | |
191 | ||
192 | Unfortunately, on some chip revisions, this sensor is very inaccurate | |
193 | and in many cases, does not work at all, so don't assume the cpu | |
194 | temp is actually what /proc/cpuinfo says it is. | |
195 | ||
196 | config TAU_INT | |
197 | bool "Interrupt driven TAU driver (DANGEROUS)" | |
198 | depends on TAU | |
199 | ---help--- | |
200 | The TAU supports an interrupt driven mode which causes an interrupt | |
201 | whenever the temperature goes out of range. This is the fastest way | |
202 | to get notified the temp has exceeded a range. With this option off, | |
203 | a timer is used to re-check the temperature periodically. | |
204 | ||
205 | However, on some cpus it appears that the TAU interrupt hardware | |
206 | is buggy and can cause a situation which would lead unexplained hard | |
207 | lockups. | |
208 | ||
209 | Unless you are extending the TAU driver, or enjoy kernel/hardware | |
210 | debugging, leave this option off. | |
211 | ||
212 | config TAU_AVERAGE | |
213 | bool "Average high and low temp" | |
214 | depends on TAU | |
215 | ---help--- | |
216 | The TAU hardware can compare the temperature to an upper and lower | |
217 | bound. The default behavior is to show both the upper and lower | |
218 | bound in /proc/cpuinfo. If the range is large, the temperature is | |
219 | either changing a lot, or the TAU hardware is broken (likely on some | |
220 | G4's). If the range is small (around 4 degrees), the temperature is | |
221 | relatively stable. If you say Y here, a single temperature value, | |
222 | halfway between the upper and lower bounds, will be reported in | |
223 | /proc/cpuinfo. | |
224 | ||
225 | If in doubt, say N here. | |
