79 prompt "Processor Type"
83 bool "6xx/7xx/74xx/52xx/82xx"
86 There are four types of PowerPC chips supported. The more common
87 types (601, 603, 604, 740, 750, 7400), the older Freescale
88 (formerly Motorola) embedded versions (821, 823, 850, 855, 860,
89 52xx, 82xx), the IBM embedded versions (403 and 405) and
90 the Book E embedded processors from IBM (44x) and Freescale (85xx).
91 For support for 64-bit processors, set ARCH=powerpc.
92 Unless you are building a kernel for one of the embedded processor
94 Also note that because the 52xx, 82xx family have a 603e
95 core, specific support for that chipset is asked later on.
103 select PPC_DCR_NATIVE
114 config PPC_DCR_NATIVE
120 depends on PPC_DCR_NATIVE
133 This option enables kernel support for larger than 32-bit physical
134 addresses. This features is not be available on all e500 cores.
136 If in doubt, say N here.
139 bool "AltiVec Support"
143 This option enables kernel support for the Altivec extensions to the
144 PowerPC processor. The kernel currently supports saving and restoring
145 altivec registers, and turning on the 'altivec enable' bit so user
146 processes can execute altivec instructions.
148 This option is only usefully if you have a processor that supports
149 altivec (G4, otherwise known as 74xx series), but does not have
150 any affect on a non-altivec cpu (it does, however add code to the
153 If in doubt, say Y here.
156 bool "Thermal Management Support"
157 depends on 6xx && !8260
159 G3 and G4 processors have an on-chip temperature sensor called the
160 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
161 temperature within 2-4 degrees Celsius. This option shows the current
162 on-die temperature in /proc/cpuinfo if the cpu supports it.
164 Unfortunately, on some chip revisions, this sensor is very inaccurate
165 and in some cases, does not work at all, so don't assume the cpu
166 temp is actually what /proc/cpuinfo says it is.
169 bool "Interrupt driven TAU driver (DANGEROUS)"
172 The TAU supports an interrupt driven mode which causes an interrupt
173 whenever the temperature goes out of range. This is the fastest way
174 to get notified the temp has exceeded a range. With this option off,
175 a timer is used to re-check the temperature periodically.
177 However, on some cpus it appears that the TAU interrupt hardware
178 is buggy and can cause a situation which would lead unexplained hard
181 Unless you are extending the TAU driver, or enjoy kernel/hardware
182 debugging, leave this option off.
185 bool "Average high and low temp"
188 The TAU hardware can compare the temperature to an upper and lower
189 bound. The default behavior is to show both the upper and lower
190 bound in /proc/cpuinfo. If the range is large, the temperature is
191 either changing a lot, or the TAU hardware is broken (likely on some
192 G4's). If the range is small (around 4 degrees), the temperature is
193 relatively stable. If you say Y here, a single temperature value,
194 halfway between the upper and lower bounds, will be reported in
197 If in doubt, say N here.
199 config MATH_EMULATION
200 bool "Math emulation"
201 depends on 4xx || 8xx
203 Some PowerPC chips designed for embedded applications do not have
204 a floating-point unit and therefore do not implement the
205 floating-point instructions in the PowerPC instruction set. If you
206 say Y here, the kernel will include code to emulate a floating-point
207 unit, which will allow programs that use floating-point
210 If you have an Apple machine or an IBM RS/6000 or pSeries machine,
211 or any machine with a 6xx, 7xx or 7xxx series processor, say N
212 here. Saying Y here will not hurt performance (on any machine) but
213 will increase the size of the kernel.
216 bool "kexec system call (EXPERIMENTAL)"
217 depends on EXPERIMENTAL
219 kexec is a system call that implements the ability to shutdown your
220 current kernel, and to start another kernel. It is like a reboot
221 but it is independent of the system firmware. And like a reboot
222 you can start any kernel with it, not just Linux.
224 The name comes from the similarity to the exec system call.
226 It is an ongoing process to be certain the hardware in a machine
227 is properly shutdown, so do not be surprised if this code does not
228 initially work for you. It may help to enable device hotplugging
229 support. As of this writing the exact hardware interface is
230 strongly in flux, so no good recommendation can be made.
232 In the GameCube implementation, kexec allows you to load and
233 run DOL files, including kernel and homebrew DOLs.
235 source "drivers/cpufreq/Kconfig"
237 config PPC601_SYNC_FIX
238 bool "Workarounds for PPC601 bugs"
239 depends on 6xx && PPC_PREP
241 Some versions of the PPC601 (the first PowerPC chip) have bugs which
242 mean that extra synchronization instructions are required near
243 certain instructions, typically those that make major changes to the
244 CPU state. These extra instructions reduce performance slightly.
245 If you say N here, these extra instructions will not be included,
246 resulting in a kernel which will run faster but may not run at all
247 on some systems with the PPC601 chip.
249 If in doubt, say Y here.

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

1003 have an IBM RS/6000 or pSeries machine or a PReP machine, say Y. If
1004 you have an embedded board, consult your board documentation.
