55 prompt "Processor Type"
59 bool "6xx/7xx/74xx/52xx/82xx/83xx"
62 There are four types of PowerPC chips supported. The more common
63 types (601, 603, 604, 740, 750, 7400), the Motorola embedded
64 versions (821, 823, 850, 855, 860, 52xx, 82xx, 83xx), the IBM embedded
65 versions (403 and 405) and the high end 64 bit Power processors
66 (POWER 3, POWER4, and IBM 970 also known as G5)
67 Unless you are building a kernel for one of the embedded processor
68 systems, 64 bit IBM RS/6000 or an Apple G5, choose 6xx.
69 Note that the kernel runs in 32-bit mode even on 64-bit chips.
70 Also note that because the 52xx, 82xx, & 83xx family has a 603e core,
71 specific support for that chipset is asked later on.

104 depends on E200 || E500

116 default y if E500 && PHYS_64BIT
119 bool 'Large physical address support' if E500
120 depends on 44x || E500
123 This option enables kernel support for larger than 32-bit physical
124 addresses. This features is not be available on all e500 cores.
126 If in doubt, say N here.
129 bool "AltiVec Support"
130 depends on 6xx || POWER4
131 depends on !8260 && !83xx
133 This option enables kernel support for the Altivec extensions to the
134 PowerPC processor. The kernel currently supports saving and restoring
135 altivec registers, and turning on the 'altivec enable' bit so user
136 processes can execute altivec instructions.
138 This option is only usefully if you have a processor that supports
139 altivec (G4, otherwise known as 74xx series), but does not have
140 any affect on a non-altivec cpu (it does, however add code to the
143 If in doubt, say Y here.
147 depends on E200 || E500
149 This option enables kernel support for the Signal Processing
150 Extensions (SPE) to the PowerPC processor. The kernel currently
151 supports saving and restoring SPE registers, and turning on the
152 'spe enable' bit so user processes can execute SPE instructions.
154 This option is only useful if you have a processor that supports
155 SPE (e500, otherwise known as 85xx series), but does not have any
156 effect on a non-spe cpu (it does, however add code to the kernel).
158 If in doubt, say Y here.
161 bool "Thermal Management Support"
162 depends on 6xx && !8260 && !83xx
164 G3 and G4 processors have an on-chip temperature sensor called the
165 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
166 temperature within 2-4 degrees Celsius. This option shows the current
167 on-die temperature in /proc/cpuinfo if the cpu supports it.
169 Unfortunately, on some chip revisions, this sensor is very inaccurate
170 and in some cases, does not work at all, so don't assume the cpu
171 temp is actually what /proc/cpuinfo says it is.
174 bool "Interrupt driven TAU driver (DANGEROUS)"
177 The TAU supports an interrupt driven mode which causes an interrupt
178 whenever the temperature goes out of range. This is the fastest way
179 to get notified the temp has exceeded a range. With this option off,
180 a timer is used to re-check the temperature periodically.
182 However, on some cpus it appears that the TAU interrupt hardware
183 is buggy and can cause a situation which would lead unexplained hard
186 Unless you are extending the TAU driver, or enjoy kernel/hardware
187 debugging, leave this option off.
190 bool "Average high and low temp"
193 The TAU hardware can compare the temperature to an upper and lower
194 bound. The default behavior is to show both the upper and lower
195 bound in /proc/cpuinfo. If the range is large, the temperature is
196 either changing a lot, or the TAU hardware is broken (likely on some
197 G4's). If the range is small (around 4 degrees), the temperature is
198 relatively stable. If you say Y here, a single temperature value,
199 halfway between the upper and lower bounds, will be reported in
202 If in doubt, say N here.
204 config MATH_EMULATION
205 bool "Math emulation"
206 depends on 4xx || 8xx || E200 || E500
208 Some PowerPC chips designed for embedded applications do not have
209 a floating-point unit and therefore do not implement the
210 floating-point instructions in the PowerPC instruction set. If you
211 say Y here, the kernel will include code to emulate a floating-point
212 unit, which will allow programs that use floating-point
215 If you have an Apple machine or an IBM RS/6000 or pSeries machine,
216 or any machine with a 6xx, 7xx or 7xxx series processor, say N
217 here. Saying Y here will not hurt performance (on any machine) but
218 will increase the size of the kernel.
221 bool "kexec system call (EXPERIMENTAL)"
222 depends on EXPERIMENTAL
224 kexec is a system call that implements the ability to shutdown your
225 current kernel, and to start another kernel. It is like a reboot
226 but it is indepedent of the system firmware. And like a reboot
227 you can start any kernel with it, not just Linux.
229 The name comes from the similiarity to the exec system call.
231 It is an ongoing process to be certain the hardware in a machine
232 is properly shutdown, so do not be surprised if this code does not
233 initially work for you. It may help to enable device hotplugging
234 support. As of this writing the exact hardware interface is
235 strongly in flux, so no good recommendation can be made.
237 In the GameCube implementation, kexec allows you to load and
238 run DOL files, including kernel and homebrew DOLs.

251 config PPC601_SYNC_FIX
252 bool "Workarounds for PPC601 bugs"
253 depends on 6xx && (PPC_PREP || PPC_PMAC)
255 Some versions of the PPC601 (the first PowerPC chip) have bugs which
256 mean that extra synchronization instructions are required near
257 certain instructions, typically those that make major changes to the
258 CPU state. These extra instructions reduce performance slightly.
259 If you say N here, these extra instructions will not be included,
260 resulting in a kernel which will run faster but may not run at all
261 on some systems with the PPC601 chip.
263 If in doubt, say Y here.

911 support SMP machines with 603/603e/603ev or PPC750 ("G3") processors
912 since they have inadequate hardware support for multiprocessor
915 If you say N here, the kernel will run on single and multiprocessor
916 machines, but will use only one CPU of a multiprocessor machine. If

961 Firmware. If unsure, say Y here.
964 bool "Support for PReP Residual Data"
967 Some PReP systems have residual data passed to the kernel by the
968 firmware. This allows detection of memory size, devices present and
969 other useful pieces of information. Sometimes this information is
970 not present or incorrect, in which case it could lead to the machine
971 behaving incorrectly. If this happens, either disable PREP_RESIDUAL
972 or pass the 'noresidual' option to the kernel.
974 If you are running a PReP system, say Y here, otherwise say N.
976 config PROC_PREPRESIDUAL
977 bool "Support for reading of PReP Residual Data in /proc"
978 depends on PREP_RESIDUAL && PROC_FS
980 Enabling this option will create a /proc/residual file which allows
981 you to get at the residual data on PReP systems. You will need a tool
982 (lsresidual) to parse it. If you aren't on a PReP system, you don't

993 On some platforms, there is currently no way for the boot loader to
994 pass arguments to the kernel. For these platforms, you can supply
995 some command-line options at build time by entering them here. In
996 most cases you will need to specify the root device here.
1003 This option enables support for the Amiga series of computers.
1010 This enables support for the Zorro bus in the Amiga. If you have
1011 expansion cards in your Amiga that conform to the Amiga
1012 AutoConfig(tm) specification, say Y, otherwise N. Note that even
1013 expansion cards that do not fit in the Zorro slots but fit in e.g.
1014 the CPU slot may fall in this category, so you have to say Y to let

1074 tristate "Commodore A2232 serial support (EXPERIMENTAL)"
1075 depends on EXPERIMENTAL && APUS
1077 This option supports the 2232 7-port serial card shipped with the
1078 Amiga 2000 and other Zorro-bus machines, dating from 1989. At
1079 a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
1080 each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
1081 ports were connected with 8 pin DIN connectors on the card bracket,
1082 for which 8 pin to DB25 adapters were supplied. The card also had
1083 jumpers internally to toggle various pinning configurations.
1085 This driver can be built as a module; but then "generic_serial"
1086 will also be built as a module. This has to be loaded before
1087 "ser_a2232". If you want to do this, answer M here.

1131 This kernel feature is useful for number crunching applications
1132 that may need to compute untrusted bytecode during their
1133 execution. By using pipes or other transports made available to
1134 the process as file descriptors supporting the read/write
1135 syscalls, it's possible to isolate those applications in
1136 their own address space using seccomp. Once seccomp is
1137 enabled via /proc/<pid>/seccomp, it cannot be disabled
1138 and the task is only allowed to execute a few safe syscalls
1139 defined by each seccomp mode.
