73 prompt "Processor Type"
77 bool "6xx/7xx/74xx/52xx/82xx/83xx"
80 There are four types of PowerPC chips supported. The more common
81 types (601, 603, 604, 740, 750, 7400), the older Freescale
82 (formerly Motorola) embedded versions (821, 823, 850, 855, 860,
83 52xx, 82xx, 83xx), the IBM embedded versions (403 and 405) and
84 the Book E embedded processors from IBM (44x) and Freescale (85xx).
85 For support for 64-bit processors, set ARCH=powerpc.
86 Unless you are building a kernel for one of the embedded processor
88 Also note that because the 52xx, 82xx, & 83xx family have a 603e
89 core, specific support for that chipset is asked later on.

136 default y if E500 && PHYS_64BIT
139 bool 'Large physical address support' if E500
140 depends on 44x || E500
143 This option enables kernel support for larger than 32-bit physical
144 addresses. This features is not be available on all e500 cores.
146 If in doubt, say N here.
149 bool "AltiVec Support"
151 depends on !8260 && !83xx
153 This option enables kernel support for the Altivec extensions to the
154 PowerPC processor. The kernel currently supports saving and restoring
155 altivec registers, and turning on the 'altivec enable' bit so user
156 processes can execute altivec instructions.
158 This option is only usefully if you have a processor that supports
159 altivec (G4, otherwise known as 74xx series), but does not have
160 any affect on a non-altivec cpu (it does, however add code to the
163 If in doubt, say Y here.
167 depends on E200 || E500
169 This option enables kernel support for the Signal Processing
170 Extensions (SPE) to the PowerPC processor. The kernel currently
171 supports saving and restoring SPE registers, and turning on the
172 'spe enable' bit so user processes can execute SPE instructions.
174 This option is only useful if you have a processor that supports
175 SPE (e500, otherwise known as 85xx series), but does not have any
176 effect on a non-spe cpu (it does, however add code to the kernel).
178 If in doubt, say Y here.
181 bool "Thermal Management Support"
182 depends on 6xx && !8260 && !83xx
184 G3 and G4 processors have an on-chip temperature sensor called the
185 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
186 temperature within 2-4 degrees Celsius. This option shows the current
187 on-die temperature in /proc/cpuinfo if the cpu supports it.
189 Unfortunately, on some chip revisions, this sensor is very inaccurate
190 and in some cases, does not work at all, so don't assume the cpu
191 temp is actually what /proc/cpuinfo says it is.
194 bool "Interrupt driven TAU driver (DANGEROUS)"
197 The TAU supports an interrupt driven mode which causes an interrupt
198 whenever the temperature goes out of range. This is the fastest way
199 to get notified the temp has exceeded a range. With this option off,
200 a timer is used to re-check the temperature periodically.
202 However, on some cpus it appears that the TAU interrupt hardware
203 is buggy and can cause a situation which would lead unexplained hard
206 Unless you are extending the TAU driver, or enjoy kernel/hardware
207 debugging, leave this option off.
210 bool "Average high and low temp"
213 The TAU hardware can compare the temperature to an upper and lower
214 bound. The default behavior is to show both the upper and lower
215 bound in /proc/cpuinfo. If the range is large, the temperature is
216 either changing a lot, or the TAU hardware is broken (likely on some
217 G4's). If the range is small (around 4 degrees), the temperature is
218 relatively stable. If you say Y here, a single temperature value,
219 halfway between the upper and lower bounds, will be reported in
222 If in doubt, say N here.
224 config MATH_EMULATION
225 bool "Math emulation"
226 depends on 4xx || 8xx || E200 || E500
228 Some PowerPC chips designed for embedded applications do not have
229 a floating-point unit and therefore do not implement the
230 floating-point instructions in the PowerPC instruction set. If you
231 say Y here, the kernel will include code to emulate a floating-point
232 unit, which will allow programs that use floating-point
235 If you have an Apple machine or an IBM RS/6000 or pSeries machine,
236 or any machine with a 6xx, 7xx or 7xxx series processor, say N
237 here. Saying Y here will not hurt performance (on any machine) but
238 will increase the size of the kernel.
241 bool "kexec system call (EXPERIMENTAL)"
242 depends on EXPERIMENTAL
244 kexec is a system call that implements the ability to shutdown your
245 current kernel, and to start another kernel. It is like a reboot
246 but it is independent of the system firmware. And like a reboot
247 you can start any kernel with it, not just Linux.
249 The name comes from the similarity to the exec system call.
251 It is an ongoing process to be certain the hardware in a machine
252 is properly shutdown, so do not be surprised if this code does not
253 initially work for you. It may help to enable device hotplugging
254 support. As of this writing the exact hardware interface is
255 strongly in flux, so no good recommendation can be made.
257 In the GameCube implementation, kexec allows you to load and
258 run DOL files, including kernel and homebrew DOLs.
260 source "drivers/cpufreq/Kconfig"
262 config PPC601_SYNC_FIX
263 bool "Workarounds for PPC601 bugs"
264 depends on 6xx && PPC_PREP
266 Some versions of the PPC601 (the first PowerPC chip) have bugs which
267 mean that extra synchronization instructions are required near
268 certain instructions, typically those that make major changes to the
269 CPU state. These extra instructions reduce performance slightly.
270 If you say N here, these extra instructions will not be included,
271 resulting in a kernel which will run faster but may not run at all
272 on some systems with the PPC601 chip.
274 If in doubt, say Y here.

993 Some PReP systems have residual data passed to the kernel by the
994 firmware. This allows detection of memory size, devices present and
995 other useful pieces of information. Sometimes this information is
996 not present or incorrect, in which case it could lead to the machine
997 behaving incorrectly. If this happens, either disable PREP_RESIDUAL
998 or pass the 'noresidual' option to the kernel.

1006 Enabling this option will create a /proc/residual file which allows
1007 you to get at the residual data on PReP systems. You will need a tool
1008 (lsresidual) to parse it. If you aren't on a PReP system, you don't

1021 some command-line options at build time by entering them here. In
1022 most cases you will need to specify the root device here.

1036 This enables support for the Zorro bus in the Amiga. If you have
1037 expansion cards in your Amiga that conform to the Amiga
1038 AutoConfig(tm) specification, say Y, otherwise N. Note that even
1039 expansion cards that do not fit in the Zorro slots but fit in e.g.

1101 depends on EXPERIMENTAL && APUS
1103 This option supports the 2232 7-port serial card shipped with the
1104 Amiga 2000 and other Zorro-bus machines, dating from 1989. At
1105 a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
1106 each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
1107 ports were connected with 8 pin DIN connectors on the card bracket,
1108 for which 8 pin to DB25 adapters were supplied. The card also had
1109 jumpers internally to toggle various pinning configurations.
1111 This driver can be built as a module; but then "generic_serial"
1112 will also be built as a module. This has to be loaded before
1113 "ser_a2232". If you want to do this, answer M here.

1155 bool "Enable seccomp to safely compute untrusted bytecode"
1159 This kernel feature is useful for number crunching applications
1160 that may need to compute untrusted bytecode during their
1161 execution. By using pipes or other transports made available to
1162 the process as file descriptors supporting the read/write
1163 syscalls, it's possible to isolate those applications in
1164 their own address space using seccomp. Once seccomp is
1165 enabled via /proc/<pid>/seccomp, it cannot be disabled
1166 and the task is only allowed to execute a few safe syscalls
1167 defined by each seccomp mode.
