84 bool "6xx/7xx/74xx/52xx/82xx"
87 There are four types of PowerPC chips supported. The more common
88 types (601, 603, 604, 740, 750, 7400), the older Freescale
89 (formerly Motorola) embedded versions (821, 823, 850, 855, 860,
90 52xx, 82xx), the IBM embedded versions (403 and 405) and
91 the Book E embedded processors from IBM (44x) and Freescale (85xx).
92 For support for 64-bit processors, set ARCH=powerpc.
93 Unless you are building a kernel for one of the embedded processor
95 Also note that because the 52xx, 82xx family have a 603e
96 core, specific support for that chipset is asked later on.

121 depends on PPC_DCR_NATIVE
134 This option enables kernel support for larger than 32-bit physical
135 addresses. This features is not be available on all e500 cores.
137 If in doubt, say N here.
140 bool "AltiVec Support"
144 This option enables kernel support for the Altivec extensions to the
145 PowerPC processor. The kernel currently supports saving and restoring
146 altivec registers, and turning on the 'altivec enable' bit so user
147 processes can execute altivec instructions.
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
154 If in doubt, say Y here.
157 bool "Thermal Management Support"
158 depends on 6xx && !8260
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.
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.
170 bool "Interrupt driven TAU driver (DANGEROUS)"
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.
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
182 Unless you are extending the TAU driver, or enjoy kernel/hardware
183 debugging, leave this option off.
186 bool "Average high and low temp"
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
198 If in doubt, say N here.
200 config MATH_EMULATION
201 bool "Math emulation"
202 depends on 4xx || 8xx
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
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.
217 bool "kexec system call (EXPERIMENTAL)"
218 depends on EXPERIMENTAL
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
222 but it is independent of the system firmware. And like a reboot
223 you can start any kernel with it, not just Linux.
225 The name comes from the similarity to the exec system call.
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.
233 In the GameCube implementation, kexec allows you to load and
234 run DOL files, including kernel and homebrew DOLs.
236 source "drivers/cpufreq/Kconfig"
238 config PPC601_SYNC_FIX
239 bool "Workarounds for PPC601 bugs"
240 depends on 6xx && PPC_PREP
242 Some versions of the PPC601 (the first PowerPC chip) have bugs which
243 mean that extra synchronization instructions are required near
244 certain instructions, typically those that make major changes to the
245 CPU state. These extra instructions reduce performance slightly.
246 If you say N here, these extra instructions will not be included,
247 resulting in a kernel which will run faster but may not run at all
248 on some systems with the PPC601 chip.
250 If in doubt, say Y here.

977 This kernel feature is useful for number crunching applications
978 that may need to compute untrusted bytecode during their
979 execution. By using pipes or other transports made available to
980 the process as file descriptors supporting the read/write
981 syscalls, it's possible to isolate those applications in
982 their own address space using seccomp. Once seccomp is
983 enabled via /proc/<pid>/seccomp, it cannot be disabled
984 and the task is only allowed to execute a few safe syscalls
985 defined by each seccomp mode.
987 If unsure, say Y. Only embedded should say N here.
998 bool "Support for ISA-bus hardware"
1001 Find out whether you have ISA slots on your motherboard. ISA is the
1002 name of a bus system, i.e. the way the CPU talks to the other stuff
1003 inside your box. If you have an Apple machine, say N here; if you
1004 have an IBM RS/6000 or pSeries machine or a PReP machine, say Y. If
1005 you have an embedded board, consult your board documentation.

1047 your box. If you say Y here, the kernel will include drivers and
1048 infrastructure code to support PCI bus devices.
