87 | There are four types of PowerPC chips supported. The more common | |
0a26b136 PM |
88 | types (601, 603, 604, 740, 750, 7400), the older Freescale |
89 | (formerly Motorola) embedded versions (821, 823, 850, 855, 860, | |
3155f7f2 | 90 | 52xx, 82xx), the IBM embedded versions (403 and 405) and |
0a26b136 PM |
91 | the Book E embedded processors from IBM (44x) and Freescale (85xx). |
92 | For support for 64-bit processors, set ARCH=powerpc. | |
1da177e4 | 93 | Unless you are building a kernel for one of the embedded processor |
0a26b136 | 94 | systems, choose 6xx. |
3155f7f2 | 95 | Also note that because the 52xx, 82xx family have a 603e |
0a26b136 | 96 | core, specific support for that chipset is asked later on. |

144 | This option enables kernel support for the Altivec extensions to the | |

146 | altivec registers, and turning on the 'altivec enable' bit so user | |
147 | processes can execute altivec instructions. | |
148 | ||
149 | This option is only usefully if you have a processor that supports | |
150 | altivec (G4, otherwise known as 74xx series), but does not have | |
151 | any affect on a non-altivec cpu (it does, however add code to the | |

3155f7f2 | 158 | depends on 6xx && !8260 |
1da177e4 LT |
159 | help |
160 | G3 and G4 processors have an on-chip temperature sensor called the | |
161 | 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die | |
162 | temperature within 2-4 degrees Celsius. This option shows the current | |
163 | on-die temperature in /proc/cpuinfo if the cpu supports it. | |
164 | ||
165 | Unfortunately, on some chip revisions, this sensor is very inaccurate | |
166 | and in some cases, does not work at all, so don't assume the cpu | |
167 | temp is actually what /proc/cpuinfo says it is. | |
168 | ||
169 | config TAU_INT | |
170 | bool "Interrupt driven TAU driver (DANGEROUS)" | |
171 | depends on TAU | |
172 | ---help--- | |
173 | The TAU supports an interrupt driven mode which causes an interrupt | |
174 | whenever the temperature goes out of range. This is the fastest way | |
175 | to get notified the temp has exceeded a range. With this option off, | |
176 | a timer is used to re-check the temperature periodically. | |
177 | ||
178 | However, on some cpus it appears that the TAU interrupt hardware | |
179 | is buggy and can cause a situation which would lead unexplained hard | |
180 | lockups. | |
181 | ||
182 | Unless you are extending the TAU driver, or enjoy kernel/hardware | |
183 | debugging, leave this option off. | |
184 | ||
185 | config TAU_AVERAGE | |
186 | bool "Average high and low temp" | |
187 | depends on TAU | |
188 | ---help--- | |
189 | The TAU hardware can compare the temperature to an upper and lower | |
190 | bound. The default behavior is to show both the upper and lower | |
191 | bound in /proc/cpuinfo. If the range is large, the temperature is | |
192 | either changing a lot, or the TAU hardware is broken (likely on some | |
193 | G4's). If the range is small (around 4 degrees), the temperature is | |
194 | relatively stable. If you say Y here, a single temperature value, | |
195 | halfway between the upper and lower bounds, will be reported in | |
196 | /proc/cpuinfo. | |

1da177e4 LT |
203 | ---help--- |
204 | Some PowerPC chips designed for embedded applications do not have | |
205 | a floating-point unit and therefore do not implement the | |
206 | floating-point instructions in the PowerPC instruction set. If you | |
207 | say Y here, the kernel will include code to emulate a floating-point | |
208 | unit, which will allow programs that use floating-point | |
209 | instructions to run. | |
210 | ||
211 | If you have an Apple machine or an IBM RS/6000 or pSeries machine, | |
212 | or any machine with a 6xx, 7xx or 7xxx series processor, say N | |
213 | here. Saying Y here will not hurt performance (on any machine) but | |
214 | will increase the size of the kernel. | |

216 | config KEXEC |
217 | bool "kexec system call (EXPERIMENTAL)" | |
218 | depends on EXPERIMENTAL | |
219 | help | |
220 | kexec is a system call that implements the ability to shutdown your | |
221 | current kernel, and to start another kernel. It is like a reboot | |
1f1332f7 | 222 | but it is independent of the system firmware. And like a reboot |
70765aa4 EB |
223 | you can start any kernel with it, not just Linux. |
224 | ||
1f1332f7 | 225 | The name comes from the similarity to the exec system call. |
70765aa4 EB |
226 | |
227 | It is an ongoing process to be certain the hardware in a machine | |
228 | is properly shutdown, so do not be surprised if this code does not | |
229 | initially work for you. It may help to enable device hotplugging | |
230 | support. As of this writing the exact hardware interface is | |
231 | strongly in flux, so no good recommendation can be made. | |
232 | ||
233 | In the GameCube implementation, kexec allows you to load and | |
234 | run DOL files, including kernel and homebrew DOLs. | |

242 | Some versions of the PPC601 (the first PowerPC chip) have bugs which | |

245 | CPU state. These extra instructions reduce performance slightly. | |
246 | If you say N here, these extra instructions will not be included, | |

937 | Some PReP systems have residual data passed to the kernel by the | |
938 | firmware. This allows detection of memory size, devices present and | |
939 | other useful pieces of information. Sometimes this information is | |
940 | not present or incorrect, in which case it could lead to the machine | |
941 | behaving incorrectly. If this happens, either disable PREP_RESIDUAL | |
