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.
85 bool "POWER4 and 970 (G5)"
103 depends on E200 || E500
108 depends on E200 || E500
113 depends on 44x || E500
115 default y if E500 && PHYS_64BIT
118 bool 'Large physical address support' if E500
119 depends on 44x || E500
122 This option enables kernel support for larger than 32-bit physical
123 addresses. This features is not be available on all e500 cores.
125 If in doubt, say N here.
128 bool "AltiVec Support"
129 depends on 6xx || POWER4
130 depends on !8260 && !83xx
132 This option enables kernel support for the Altivec extensions to the
133 PowerPC processor. The kernel currently supports saving and restoring
134 altivec registers, and turning on the 'altivec enable' bit so user
135 processes can execute altivec instructions.
137 This option is only usefully if you have a processor that supports
138 altivec (G4, otherwise known as 74xx series), but does not have
139 any affect on a non-altivec cpu (it does, however add code to the
142 If in doubt, say Y here.
146 depends on E200 || E500
148 This option enables kernel support for the Signal Processing
149 Extensions (SPE) to the PowerPC processor. The kernel currently
150 supports saving and restoring SPE registers, and turning on the
151 'spe enable' bit so user processes can execute SPE instructions.
153 This option is only useful if you have a processor that supports
154 SPE (e500, otherwise known as 85xx series), but does not have any
155 effect on a non-spe cpu (it does, however add code to the kernel).
157 If in doubt, say Y here.
160 bool "Thermal Management Support"
161 depends on 6xx && !8260 && !83xx
163 G3 and G4 processors have an on-chip temperature sensor called the
164 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
165 temperature within 2-4 degrees Celsius. This option shows the current
166 on-die temperature in /proc/cpuinfo if the cpu supports it.
168 Unfortunately, on some chip revisions, this sensor is very inaccurate
169 and in some cases, does not work at all, so don't assume the cpu
170 temp is actually what /proc/cpuinfo says it is.
173 bool "Interrupt driven TAU driver (DANGEROUS)"
176 The TAU supports an interrupt driven mode which causes an interrupt
177 whenever the temperature goes out of range. This is the fastest way
178 to get notified the temp has exceeded a range. With this option off,
179 a timer is used to re-check the temperature periodically.
181 However, on some cpus it appears that the TAU interrupt hardware
182 is buggy and can cause a situation which would lead unexplained hard
185 Unless you are extending the TAU driver, or enjoy kernel/hardware
186 debugging, leave this option off.
189 bool "Average high and low temp"
192 The TAU hardware can compare the temperature to an upper and lower
193 bound. The default behavior is to show both the upper and lower
194 bound in /proc/cpuinfo. If the range is large, the temperature is
195 either changing a lot, or the TAU hardware is broken (likely on some
196 G4's). If the range is small (around 4 degrees), the temperature is
197 relatively stable. If you say Y here, a single temperature value,
198 halfway between the upper and lower bounds, will be reported in
201 If in doubt, say N here.
203 config MATH_EMULATION
204 bool "Math emulation"
205 depends on 4xx || 8xx || E200 || E500
207 Some PowerPC chips designed for embedded applications do not have
208 a floating-point unit and therefore do not implement the
209 floating-point instructions in the PowerPC instruction set. If you
210 say Y here, the kernel will include code to emulate a floating-point
211 unit, which will allow programs that use floating-point
214 If you have an Apple machine or an IBM RS/6000 or pSeries machine,
215 or any machine with a 6xx, 7xx or 7xxx series processor, say N
216 here. Saying Y here will not hurt performance (on any machine) but
217 will increase the size of the kernel.
220 bool "kexec system call (EXPERIMENTAL)"
221 depends on EXPERIMENTAL
223 kexec is a system call that implements the ability to shutdown your
224 current kernel, and to start another kernel. It is like a reboot
225 but it is indepedent of the system firmware. And like a reboot
226 you can start any kernel with it, not just Linux.
228 The name comes from the similiarity to the exec system call.
230 It is an ongoing process to be certain the hardware in a machine
231 is properly shutdown, so do not be surprised if this code does not
232 initially work for you. It may help to enable device hotplugging
233 support. As of this writing the exact hardware interface is
234 strongly in flux, so no good recommendation can be made.
236 In the GameCube implementation, kexec allows you to load and
237 run DOL files, including kernel and homebrew DOLs.

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

269 CPUs at runtime on SMP machines.

893 support SMP machines with 603/603e/603ev or PPC750 ("G3") processors
894 since they have inadequate hardware support for multiprocessor

955 you to get at the residual data on PReP systems. You will need a tool
956 (lsresidual) to parse it. If you aren't on a PReP system, you don't

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

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

1051 This option supports the 2232 7-port serial card shipped with the
1052 Amiga 2000 and other Zorro-bus machines, dating from 1989. At
1053 a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
1054 each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
1055 ports were connected with 8 pin DIN connectors on the card bracket,
1056 for which 8 pin to DB25 adapters were supplied. The card also had
1057 jumpers internally to toggle various pinning configurations.
1059 This driver can be built as a module; but then "generic_serial"
1060 will also be built as a module. This has to be loaded before

1107 This kernel feature is useful for number crunching applications
1108 that may need to compute untrusted bytecode during their
1109 execution. By using pipes or other transports made available to
1110 the process as file descriptors supporting the read/write
1111 syscalls, it's possible to isolate those applications in
1112 their own address space using seccomp. Once seccomp is
1113 enabled via /proc/<pid>/seccomp, it cannot be disabled
1114 and the task is only allowed to execute a few safe syscalls
1115 defined by each seccomp mode.
