80 There are four types of PowerPC chips supported. The more common
81 types (601, 603, 604, 740, 750, 7400), the older Freescale
82 (formerly Motorola) embedded versions (821, 823, 850, 855, 860,
83 52xx, 82xx, 83xx), the IBM embedded versions (403 and 405) and
84 the Book E embedded processors from IBM (44x) and Freescale (85xx).
85 For support for 64-bit processors, set ARCH=powerpc.
86 Unless you are building a kernel for one of the embedded processor
87 systems, choose 6xx.
88 Also note that because the 52xx, 82xx, & 83xx family have a 603e

155 altivec registers, and turning on the 'altivec enable' bit so user
156 processes can execute altivec instructions.
157
158 This option is only usefully if you have a processor that supports
159 altivec (G4, otherwise known as 74xx series), but does not have

173
174 This option is only useful if you have a processor that supports
175 SPE (e500, otherwise known as 85xx series), but does not have any
176 effect on a non-spe cpu (it does, however add code to the kernel).

180config TAU
181 bool "Thermal Management Support"
182 depends on 6xx && !8260 && !83xx
183 help
184 G3 and G4 processors have an on-chip temperature sensor called the
185 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
186 temperature within 2-4 degrees Celsius. This option shows the current
187 on-die temperature in /proc/cpuinfo if the cpu supports it.
188
189 Unfortunately, on some chip revisions, this sensor is very inaccurate
190 and in some cases, does not work at all, so don't assume the cpu
191 temp is actually what /proc/cpuinfo says it is.
192
193config TAU_INT
194 bool "Interrupt driven TAU driver (DANGEROUS)"
195 depends on TAU
196 ---help---
197 The TAU supports an interrupt driven mode which causes an interrupt
198 whenever the temperature goes out of range. This is the fastest way
199 to get notified the temp has exceeded a range. With this option off,
200 a timer is used to re-check the temperature periodically.
201
202 However, on some cpus it appears that the TAU interrupt hardware
203 is buggy and can cause a situation which would lead unexplained hard
204 lockups.
205
206 Unless you are extending the TAU driver, or enjoy kernel/hardware
207 debugging, leave this option off.
208
209config TAU_AVERAGE
210 bool "Average high and low temp"
211 depends on TAU
212 ---help---
213 The TAU hardware can compare the temperature to an upper and lower
214 bound. The default behavior is to show both the upper and lower
215 bound in /proc/cpuinfo. If the range is large, the temperature is
216 either changing a lot, or the TAU hardware is broken (likely on some
217 G4's). If the range is small (around 4 degrees), the temperature is
218 relatively stable. If you say Y here, a single temperature value,
219 halfway between the upper and lower bounds, will be reported in
220 /proc/cpuinfo.
221
222 If in doubt, say N here.
223
224config MATH_EMULATION
225 bool "Math emulation"
226 depends on 4xx || 8xx || E200 || E500
227 ---help---
228 Some PowerPC chips designed for embedded applications do not have
229 a floating-point unit and therefore do not implement the
230 floating-point instructions in the PowerPC instruction set. If you
231 say Y here, the kernel will include code to emulate a floating-point
232 unit, which will allow programs that use floating-point
233 instructions to run.
234
235 If you have an Apple machine or an IBM RS/6000 or pSeries machine,
236 or any machine with a 6xx, 7xx or 7xxx series processor, say N
237 here. Saying Y here will not hurt performance (on any machine) but
238 will increase the size of the kernel.
239
240config KEXEC
241 bool "kexec system call (EXPERIMENTAL)"
242 depends on EXPERIMENTAL
243 help
244 kexec is a system call that implements the ability to shutdown your
245 current kernel, and to start another kernel. It is like a reboot
246 but it is independent of the system firmware. And like a reboot
247 you can start any kernel with it, not just Linux.
248
249 The name comes from the similarity to the exec system call.
250
251 It is an ongoing process to be certain the hardware in a machine
252 is properly shutdown, so do not be surprised if this code does not
253 initially work for you. It may help to enable device hotplugging
254 support. As of this writing the exact hardware interface is
255 strongly in flux, so no good recommendation can be made.
256
257 In the GameCube implementation, kexec allows you to load and
258 run DOL files, including kernel and homebrew DOLs.

265 help
266 Some versions of the PPC601 (the first PowerPC chip) have bugs which
267 mean that extra synchronization instructions are required near
268 certain instructions, typically those that make major changes to the
269 CPU state. These extra instructions reduce performance slightly.
270 If you say N here, these extra instructions will not be included,
271 resulting in a kernel which will run faster but may not run at all
272 on some systems with the PPC601 chip.

1225 a bus system, i.e. the way the CPU talks to the other stuff inside
1226 your box. If you say Y here, the kernel will include drivers and
1227 infrastructure code to support PCI bus devices.
