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

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

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

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

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

1053 depends on EXPERIMENTAL && APUS
1055 This option supports the 2232 7-port serial card shipped with the
1056 Amiga 2000 and other Zorro-bus machines, dating from 1989. At
1057 a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
1058 each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
1059 ports were connected with 8 pin DIN connectors on the card bracket,
1060 for which 8 pin to DB25 adapters were supplied. The card also had
1061 jumpers internally to toggle various pinning configurations.
1063 This driver can be built as a module; but then "generic_serial"
1064 will also be built as a module. This has to be loaded before
1065 "ser_a2232". If you want to do this, answer M here.

1111 This kernel feature is useful for number crunching applications
1112 that may need to compute untrusted bytecode during their
1113 execution. By using pipes or other transports made available to
1114 the process as file descriptors supporting the read/write
1115 syscalls, it's possible to isolate those applications in
1116 their own address space using seccomp. Once seccomp is
1117 enabled via /proc/<pid>/seccomp, it cannot be disabled
1118 and the task is only allowed to execute a few safe syscalls
1119 defined by each seccomp mode.
