4330f5da KG |
220 | help |
221 | Some versions of the PPC601 (the first PowerPC chip) have bugs which | |
222 | mean that extra synchronization instructions are required near | |
223 | certain instructions, typically those that make major changes to the | |
224 | CPU state. These extra instructions reduce performance slightly. | |
225 | If you say N here, these extra instructions will not be included, | |
226 | resulting in a kernel which will run faster but may not run at all | |
227 | on some systems with the PPC601 chip. | |

232 | bool "On-chip CPU temperature sensor support" | |
28794d34 | 233 | depends on 6xx |
4330f5da KG |
234 | help |
235 | G3 and G4 processors have an on-chip temperature sensor called the | |
236 | 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die | |
237 | temperature within 2-4 degrees Celsius. This option shows the current | |
238 | on-die temperature in /proc/cpuinfo if the cpu supports it. | |
239 | ||
240 | Unfortunately, on some chip revisions, this sensor is very inaccurate | |
241 | and in many cases, does not work at all, so don't assume the cpu | |
242 | temp is actually what /proc/cpuinfo says it is. | |
243 | ||
244 | config TAU_INT | |
245 | bool "Interrupt driven TAU driver (DANGEROUS)" | |
246 | depends on TAU | |
247 | ---help--- | |
248 | The TAU supports an interrupt driven mode which causes an interrupt | |
249 | whenever the temperature goes out of range. This is the fastest way | |
250 | to get notified the temp has exceeded a range. With this option off, | |
251 | a timer is used to re-check the temperature periodically. | |
252 | ||
253 | However, on some cpus it appears that the TAU interrupt hardware | |
254 | is buggy and can cause a situation which would lead unexplained hard | |
255 | lockups. | |
256 | ||
257 | Unless you are extending the TAU driver, or enjoy kernel/hardware | |
258 | debugging, leave this option off. | |
259 | ||

264 | The TAU hardware can compare the temperature to an upper and lower | |
265 | bound. The default behavior is to show both the upper and lower | |
266 | bound in /proc/cpuinfo. If the range is large, the temperature is | |
267 | either changing a lot, or the TAU hardware is broken (likely on some | |
268 | G4's). If the range is small (around 4 degrees), the temperature is | |
269 | relatively stable. If you say Y here, a single temperature value, | |
270 | halfway between the upper and lower bounds, will be reported in | |
271 | /proc/cpuinfo. | |
