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

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

1001 inside your box. If you have an Apple machine, say N here; if you
1002 have an IBM RS/6000 or pSeries machine or a PReP machine, say Y. If
1003 you have an embedded board, consult your board documentation.
