52 prompt "Processor Type"
56 bool "6xx/7xx/74xx/52xx/82xx/83xx"
59 There are four types of PowerPC chips supported. The more common
60 types (601, 603, 604, 740, 750, 7400), the Motorola embedded
61 versions (821, 823, 850, 855, 860, 52xx, 82xx, 83xx), the IBM
62 embedded versions (403 and 405) and the POWER3 processor.
63 (For support for more recent 64-bit processors, set ARCH=powerpc.)
64 Unless you are building a kernel for one of the embedded processor
65 systems or a POWER3-based IBM RS/6000, choose 6xx.
66 Note that the kernel runs in 32-bit mode even on 64-bit chips.
67 Also note that because the 52xx, 82xx, & 83xx family has a 603e core,
68 specific support for that chipset is asked later on.

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

956 This option gives the kernel permission to distribute IRQs across
957 multiple CPUs. Saying N here will route all IRQs to the first
958 CPU. Generally saying Y is safe, although some problems have been
959 reported with SMP Power Macintoshes with this option enabled.

981 an image of the device tree that the kernel copies from Open
982 Firmware. If unsure, say Y here.
985 bool "Support for PReP Residual Data"
988 Some PReP systems have residual data passed to the kernel by the
989 firmware. This allows detection of memory size, devices present and
990 other useful pieces of information. Sometimes this information is
991 not present or incorrect, in which case it could lead to the machine
992 behaving incorrectly. If this happens, either disable PREP_RESIDUAL
993 or pass the 'noresidual' option to the kernel.
995 If you are running a PReP system, say Y here, otherwise say N.

1001 Enabling this option will create a /proc/residual file which allows
1002 you to get at the residual data on PReP systems. You will need a tool
1003 (lsresidual) to parse it. If you aren't on a PReP system, you don't

1015 pass arguments to the kernel. For these platforms, you can supply
1016 some command-line options at build time by entering them here. In
1017 most cases you will need to specify the root device here.
1024 This option enables support for the Amiga series of computers.
1031 This enables support for the Zorro bus in the Amiga. If you have
1032 expansion cards in your Amiga that conform to the Amiga
1033 AutoConfig(tm) specification, say Y, otherwise N. Note that even
1034 expansion cards that do not fit in the Zorro slots but fit in e.g.

1095 tristate "Commodore A2232 serial support (EXPERIMENTAL)"
1096 depends on EXPERIMENTAL && APUS
1098 This option supports the 2232 7-port serial card shipped with the
1099 Amiga 2000 and other Zorro-bus machines, dating from 1989. At
1100 a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
1101 each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
1102 ports were connected with 8 pin DIN connectors on the card bracket,
1103 for which 8 pin to DB25 adapters were supplied. The card also had
1104 jumpers internally to toggle various pinning configurations.
1106 This driver can be built as a module; but then "generic_serial"
1107 will also be built as a module. This has to be loaded before
1108 "ser_a2232". If you want to do this, answer M here.

1150 bool "Enable seccomp to safely compute untrusted bytecode"
1154 This kernel feature is useful for number crunching applications
1155 that may need to compute untrusted bytecode during their
1156 execution. By using pipes or other transports made available to
1157 the process as file descriptors supporting the read/write
1158 syscalls, it's possible to isolate those applications in
1159 their own address space using seccomp. Once seccomp is
1160 enabled via /proc/<pid>/seccomp, it cannot be disabled
1161 and the task is only allowed to execute a few safe syscalls
1162 defined by each seccomp mode.
