60 prompt "Processor Type"
64 bool "6xx/7xx/74xx/52xx/82xx/83xx"
67 There are four types of PowerPC chips supported. The more common
68 types (601, 603, 604, 740, 750, 7400), the older Freescale
69 (formerly Motorola) embedded versions (821, 823, 850, 855, 860,
70 52xx, 82xx, 83xx), the IBM embedded versions (403 and 405) and
71 the Book E embedded processors from IBM (44x) and Freescale (85xx).
72 For support for 64-bit processors, set ARCH=powerpc.
73 Unless you are building a kernel for one of the embedded processor
75 Also note that because the 52xx, 82xx, & 83xx family have a 603e
76 core, specific support for that chipset is asked later on.

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

977 bool "Support for PReP Residual Data"
980 Some PReP systems have residual data passed to the kernel by the
981 firmware. This allows detection of memory size, devices present and
982 other useful pieces of information. Sometimes this information is
983 not present or incorrect, in which case it could lead to the machine
984 behaving incorrectly. If this happens, either disable PREP_RESIDUAL
985 or pass the 'noresidual' option to the kernel.
987 If you are running a PReP system, say Y here, otherwise say N.

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

1008 some command-line options at build time by entering them here. In
1009 most cases you will need to specify the root device here.

1023 This enables support for the Zorro bus in the Amiga. If you have
1024 expansion cards in your Amiga that conform to the Amiga

1026 expansion cards that do not fit in the Zorro slots but fit in e.g.

1088 depends on EXPERIMENTAL && APUS
1090 This option supports the 2232 7-port serial card shipped with the
1091 Amiga 2000 and other Zorro-bus machines, dating from 1989. At
1092 a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
1093 each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
1094 ports were connected with 8 pin DIN connectors on the card bracket,
1095 for which 8 pin to DB25 adapters were supplied. The card also had
1096 jumpers internally to toggle various pinning configurations.
1098 This driver can be built as a module; but then "generic_serial"
1099 will also be built as a module. This has to be loaded before

1142 bool "Enable seccomp to safely compute untrusted bytecode"
1146 This kernel feature is useful for number crunching applications
1147 that may need to compute untrusted bytecode during their
1148 execution. By using pipes or other transports made available to
1149 the process as file descriptors supporting the read/write
1150 syscalls, it's possible to isolate those applications in
1151 their own address space using seccomp. Once seccomp is
1152 enabled via /proc/<pid>/seccomp, it cannot be disabled
1153 and the task is only allowed to execute a few safe syscalls
1154 defined by each seccomp mode.
