77 prompt "Processor Type"
81 bool "6xx/7xx/74xx/52xx/82xx"
84 There are four types of PowerPC chips supported. The more common
85 types (601, 603, 604, 740, 750, 7400), the older Freescale
86 (formerly Motorola) embedded versions (821, 823, 850, 855, 860,
87 52xx, 82xx), 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.
90 Unless you are building a kernel for one of the embedded processor
92 Also note that because the 52xx, 82xx family have a 603e
93 core, specific support for that chipset is asked later on.
101 select PPC_DCR_NATIVE
112 config PPC_DCR_NATIVE
118 depends on PPC_DCR_NATIVE
131 This option enables kernel support for larger than 32-bit physical
132 addresses. This features is not be available on all e500 cores.
134 If in doubt, say N here.
137 bool "AltiVec Support"
141 This option enables kernel support for the Altivec extensions to the
142 PowerPC processor. The kernel currently supports saving and restoring
143 altivec registers, and turning on the 'altivec enable' bit so user
144 processes can execute altivec instructions.
146 This option is only usefully if you have a processor that supports
147 altivec (G4, otherwise known as 74xx series), but does not have
148 any affect on a non-altivec cpu (it does, however add code to the
151 If in doubt, say Y here.
154 bool "Thermal Management Support"
155 depends on 6xx && !8260
157 G3 and G4 processors have an on-chip temperature sensor called the
158 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
159 temperature within 2-4 degrees Celsius. This option shows the current
160 on-die temperature in /proc/cpuinfo if the cpu supports it.
162 Unfortunately, on some chip revisions, this sensor is very inaccurate
163 and in some cases, does not work at all, so don't assume the cpu
164 temp is actually what /proc/cpuinfo says it is.
167 bool "Interrupt driven TAU driver (DANGEROUS)"
170 The TAU supports an interrupt driven mode which causes an interrupt
171 whenever the temperature goes out of range. This is the fastest way
172 to get notified the temp has exceeded a range. With this option off,
173 a timer is used to re-check the temperature periodically.
175 However, on some cpus it appears that the TAU interrupt hardware
176 is buggy and can cause a situation which would lead unexplained hard
179 Unless you are extending the TAU driver, or enjoy kernel/hardware
180 debugging, leave this option off.
183 bool "Average high and low temp"
186 The TAU hardware can compare the temperature to an upper and lower
187 bound. The default behavior is to show both the upper and lower
188 bound in /proc/cpuinfo. If the range is large, the temperature is
189 either changing a lot, or the TAU hardware is broken (likely on some
190 G4's). If the range is small (around 4 degrees), the temperature is
191 relatively stable. If you say Y here, a single temperature value,
192 halfway between the upper and lower bounds, will be reported in
195 If in doubt, say N here.
197 config MATH_EMULATION
198 bool "Math emulation"
199 depends on 4xx || 8xx
201 Some PowerPC chips designed for embedded applications do not have
202 a floating-point unit and therefore do not implement the
203 floating-point instructions in the PowerPC instruction set. If you
204 say Y here, the kernel will include code to emulate a floating-point
205 unit, which will allow programs that use floating-point
208 If you have an Apple machine or an IBM RS/6000 or pSeries machine,
209 or any machine with a 6xx, 7xx or 7xxx series processor, say N
210 here. Saying Y here will not hurt performance (on any machine) but
211 will increase the size of the kernel.
214 bool "kexec system call (EXPERIMENTAL)"
215 depends on EXPERIMENTAL
217 kexec is a system call that implements the ability to shutdown your
218 current kernel, and to start another kernel. It is like a reboot
219 but it is independent of the system firmware. And like a reboot
220 you can start any kernel with it, not just Linux.
222 The name comes from the similarity to the exec system call.
224 It is an ongoing process to be certain the hardware in a machine
225 is properly shutdown, so do not be surprised if this code does not
226 initially work for you. It may help to enable device hotplugging
227 support. As of this writing the exact hardware interface is
228 strongly in flux, so no good recommendation can be made.
230 In the GameCube implementation, kexec allows you to load and
231 run DOL files, including kernel and homebrew DOLs.
233 source "drivers/cpufreq/Kconfig"
235 config PPC601_SYNC_FIX
236 bool "Workarounds for PPC601 bugs"
237 depends on 6xx && PPC_PREP
239 Some versions of the PPC601 (the first PowerPC chip) have bugs which
240 mean that extra synchronization instructions are required near
241 certain instructions, typically those that make major changes to the
242 CPU state. These extra instructions reduce performance slightly.
243 If you say N here, these extra instructions will not be included,
244 resulting in a kernel which will run faster but may not run at all
245 on some systems with the PPC601 chip.
247 If in doubt, say Y here.

975 that may need to compute untrusted bytecode during their
976 execution. By using pipes or other transports made available to
977 the process as file descriptors supporting the read/write
978 syscalls, it's possible to isolate those applications in
979 their own address space using seccomp. Once seccomp is
980 enabled via /proc/<pid>/seccomp, it cannot be disabled
981 and the task is only allowed to execute a few safe syscalls
982 defined by each seccomp mode.

995 bool "Support for ISA-bus hardware"
998 Find out whether you have ISA slots on your motherboard. ISA is the
999 name of a bus system, i.e. the way the CPU talks to the other stuff
1000 inside your box. If you have an Apple machine, say N here; if you
1001 have an IBM RS/6000 or pSeries machine or a PReP machine, say Y. If
1002 you have an embedded board, consult your board documentation.
