77 prompt "Processor Type"
81 bool "6xx/7xx/74xx/52xx/82xx/83xx"
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, 83xx), 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, & 83xx family have a 603e
93 core, specific support for that chipset is asked later on.

144 bool 'Large physical address support' if E500
145 depends on 44x || E500
148 This option enables kernel support for larger than 32-bit physical
149 addresses. This features is not be available on all e500 cores.
151 If in doubt, say N here.
154 bool "AltiVec Support"
156 depends on !8260 && !83xx
158 This option enables kernel support for the Altivec extensions to the
159 PowerPC processor. The kernel currently supports saving and restoring
160 altivec registers, and turning on the 'altivec enable' bit so user
161 processes can execute altivec instructions.
163 This option is only usefully if you have a processor that supports
164 altivec (G4, otherwise known as 74xx series), but does not have
165 any affect on a non-altivec cpu (it does, however add code to the
168 If in doubt, say Y here.
172 depends on E200 || E500
174 This option enables kernel support for the Signal Processing
175 Extensions (SPE) to the PowerPC processor. The kernel currently
176 supports saving and restoring SPE registers, and turning on the
177 'spe enable' bit so user processes can execute SPE instructions.
179 This option is only useful if you have a processor that supports
180 SPE (e500, otherwise known as 85xx series), but does not have any
181 effect on a non-spe cpu (it does, however add code to the kernel).
183 If in doubt, say Y here.
186 bool "Thermal Management Support"
187 depends on 6xx && !8260 && !83xx
189 G3 and G4 processors have an on-chip temperature sensor called the
190 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
191 temperature within 2-4 degrees Celsius. This option shows the current
192 on-die temperature in /proc/cpuinfo if the cpu supports it.
194 Unfortunately, on some chip revisions, this sensor is very inaccurate
195 and in some cases, does not work at all, so don't assume the cpu
196 temp is actually what /proc/cpuinfo says it is.
199 bool "Interrupt driven TAU driver (DANGEROUS)"
202 The TAU supports an interrupt driven mode which causes an interrupt
203 whenever the temperature goes out of range. This is the fastest way
204 to get notified the temp has exceeded a range. With this option off,
205 a timer is used to re-check the temperature periodically.
207 However, on some cpus it appears that the TAU interrupt hardware
208 is buggy and can cause a situation which would lead unexplained hard
211 Unless you are extending the TAU driver, or enjoy kernel/hardware
212 debugging, leave this option off.
215 bool "Average high and low temp"
218 The TAU hardware can compare the temperature to an upper and lower
219 bound. The default behavior is to show both the upper and lower
220 bound in /proc/cpuinfo. If the range is large, the temperature is
221 either changing a lot, or the TAU hardware is broken (likely on some
222 G4's). If the range is small (around 4 degrees), the temperature is
223 relatively stable. If you say Y here, a single temperature value,
224 halfway between the upper and lower bounds, will be reported in
227 If in doubt, say N here.
229 config MATH_EMULATION
230 bool "Math emulation"
231 depends on 4xx || 8xx || E200 || E500
233 Some PowerPC chips designed for embedded applications do not have
234 a floating-point unit and therefore do not implement the
235 floating-point instructions in the PowerPC instruction set. If you
236 say Y here, the kernel will include code to emulate a floating-point
237 unit, which will allow programs that use floating-point
240 If you have an Apple machine or an IBM RS/6000 or pSeries machine,
241 or any machine with a 6xx, 7xx or 7xxx series processor, say N
242 here. Saying Y here will not hurt performance (on any machine) but
243 will increase the size of the kernel.
246 bool "kexec system call (EXPERIMENTAL)"
247 depends on EXPERIMENTAL
249 kexec is a system call that implements the ability to shutdown your
250 current kernel, and to start another kernel. It is like a reboot
251 but it is independent of the system firmware. And like a reboot
252 you can start any kernel with it, not just Linux.
254 The name comes from the similarity to the exec system call.
256 It is an ongoing process to be certain the hardware in a machine
257 is properly shutdown, so do not be surprised if this code does not
258 initially work for you. It may help to enable device hotplugging
259 support. As of this writing the exact hardware interface is
260 strongly in flux, so no good recommendation can be made.
262 In the GameCube implementation, kexec allows you to load and
263 run DOL files, including kernel and homebrew DOLs.

268 bool "Workarounds for PPC601 bugs"
269 depends on 6xx && PPC_PREP
271 Some versions of the PPC601 (the first PowerPC chip) have bugs which
272 mean that extra synchronization instructions are required near
273 certain instructions, typically those that make major changes to the
274 CPU state. These extra instructions reduce performance slightly.
275 If you say N here, these extra instructions will not be included,
276 resulting in a kernel which will run faster but may not run at all
277 on some systems with the PPC601 chip.
279 If in doubt, say Y here.

987 bool "Support for PReP Residual Data"
990 Some PReP systems have residual data passed to the kernel by the
991 firmware. This allows detection of memory size, devices present and
992 other useful pieces of information. Sometimes this information is
993 not present or incorrect, in which case it could lead to the machine
994 behaving incorrectly. If this happens, either disable PREP_RESIDUAL
995 or pass the 'noresidual' option to the kernel.
997 If you are running a PReP system, say Y here, otherwise say N.
999 config PROC_PREPRESIDUAL
1000 bool "Support for reading of PReP Residual Data in /proc"
1001 depends on PREP_RESIDUAL && PROC_FS
1003 Enabling this option will create a /proc/residual file which allows
1004 you to get at the residual data on PReP systems. You will need a tool
1005 (lsresidual) to parse it. If you aren't on a PReP system, you don't

1013 depends on CMDLINE_BOOL
1014 default "console=ttyS0,9600 console=tty0 root=/dev/sda2"
1016 On some platforms, there is currently no way for the boot loader to
1017 pass arguments to the kernel. For these platforms, you can supply
1018 some command-line options at build time by entering them here. In
1019 most cases you will need to specify the root device here.

1026 bool "Enable seccomp to safely compute untrusted bytecode"
1030 This kernel feature is useful for number crunching applications
1031 that may need to compute untrusted bytecode during their
1032 execution. By using pipes or other transports made available to
1033 the process as file descriptors supporting the read/write
1034 syscalls, it's possible to isolate those applications in
1035 their own address space using seccomp. Once seccomp is
1036 enabled via /proc/<pid>/seccomp, it cannot be disabled
1037 and the task is only allowed to execute a few safe syscalls
1038 defined by each seccomp mode.
1040 If unsure, say Y. Only embedded should say N here.
1051 bool "Support for ISA-bus hardware"
1054 Find out whether you have ISA slots on your motherboard. ISA is the
1055 name of a bus system, i.e. the way the CPU talks to the other stuff
1056 inside your box. If you have an Apple machine, say N here; if you
1057 have an IBM RS/6000 or pSeries machine or a PReP machine, say Y. If
1058 you have an embedded board, consult your board documentation.
