84 | There are four types of PowerPC chips supported. The more common | |
0a26b136 PM |
85 | types (601, 603, 604, 740, 750, 7400), the older Freescale |
86 | (formerly Motorola) embedded versions (821, 823, 850, 855, 860, | |
87 | 52xx, 82xx, 83xx), the IBM embedded versions (403 and 405) and | |
88 | the Book E embedded processors from IBM (44x) and Freescale (85xx). | |
89 | For support for 64-bit processors, set ARCH=powerpc. | |
1da177e4 | 90 | Unless you are building a kernel for one of the embedded processor |
0a26b136 PM |
91 | systems, choose 6xx. |

186 | bool "Thermal Management Support" | |
187 | depends on 6xx && !8260 && !83xx | |
188 | help | |
189 | G3 and G4 processors have an on-chip temperature sensor called the | |
190 | 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die | |
191 | temperature within 2-4 degrees Celsius. This option shows the current | |
192 | on-die temperature in /proc/cpuinfo if the cpu supports it. | |
193 | ||
194 | Unfortunately, on some chip revisions, this sensor is very inaccurate | |
195 | and in some cases, does not work at all, so don't assume the cpu | |
196 | temp is actually what /proc/cpuinfo says it is. | |
197 | ||
198 | config TAU_INT | |
199 | bool "Interrupt driven TAU driver (DANGEROUS)" | |
200 | depends on TAU | |
201 | ---help--- | |
202 | The TAU supports an interrupt driven mode which causes an interrupt | |
203 | whenever the temperature goes out of range. This is the fastest way | |
204 | to get notified the temp has exceeded a range. With this option off, | |
205 | a timer is used to re-check the temperature periodically. | |
206 | ||
207 | However, on some cpus it appears that the TAU interrupt hardware | |
208 | is buggy and can cause a situation which would lead unexplained hard | |
209 | lockups. | |
210 | ||
211 | Unless you are extending the TAU driver, or enjoy kernel/hardware | |
212 | debugging, leave this option off. | |
213 | ||
214 | config TAU_AVERAGE | |
215 | bool "Average high and low temp" | |
216 | depends on TAU | |
217 | ---help--- | |
218 | The TAU hardware can compare the temperature to an upper and lower | |
219 | bound. The default behavior is to show both the upper and lower | |
220 | bound in /proc/cpuinfo. If the range is large, the temperature is | |
221 | either changing a lot, or the TAU hardware is broken (likely on some | |
222 | G4's). If the range is small (around 4 degrees), the temperature is | |
223 | relatively stable. If you say Y here, a single temperature value, | |
224 | halfway between the upper and lower bounds, will be reported in | |
225 | /proc/cpuinfo. | |

1da177e4 LT |
232 | ---help--- |
233 | Some PowerPC chips designed for embedded applications do not have | |
234 | a floating-point unit and therefore do not implement the | |
235 | floating-point instructions in the PowerPC instruction set. If you | |
236 | say Y here, the kernel will include code to emulate a floating-point | |
237 | unit, which will allow programs that use floating-point | |
238 | instructions to run. | |
239 | ||
240 | If you have an Apple machine or an IBM RS/6000 or pSeries machine, | |
241 | or any machine with a 6xx, 7xx or 7xxx series processor, say N | |
242 | here. Saying Y here will not hurt performance (on any machine) but | |
243 | will increase the size of the kernel. | |

245 | config KEXEC |
246 | bool "kexec system call (EXPERIMENTAL)" | |
247 | depends on EXPERIMENTAL | |
248 | help | |
249 | kexec is a system call that implements the ability to shutdown your | |
250 | current kernel, and to start another kernel. It is like a reboot | |
1f1332f7 | 251 | but it is independent of the system firmware. And like a reboot |
70765aa4 EB |
252 | you can start any kernel with it, not just Linux. |
253 | ||
1f1332f7 | 254 | The name comes from the similarity to the exec system call. |
70765aa4 EB |
255 | |
256 | It is an ongoing process to be certain the hardware in a machine | |
257 | is properly shutdown, so do not be surprised if this code does not | |
258 | initially work for you. It may help to enable device hotplugging | |
259 | support. As of this writing the exact hardware interface is | |
260 | strongly in flux, so no good recommendation can be made. | |
261 | ||
262 | In the GameCube implementation, kexec allows you to load and | |
263 | run DOL files, including kernel and homebrew DOLs. | |

270 | help |
271 | Some versions of the PPC601 (the first PowerPC chip) have bugs which | |
272 | mean that extra synchronization instructions are required near | |
273 | certain instructions, typically those that make major changes to the | |
274 | CPU state. These extra instructions reduce performance slightly. | |
275 | If you say N here, these extra instructions will not be included, | |
