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

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

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

998 Enabling this option will create a /proc/residual file which allows
999 you to get at the residual data on PReP systems. You will need a tool
1000 (lsresidual) to parse it. If you aren't on a PReP system, you don't

1013 some command-line options at build time by entering them here. In
1014 most cases you will need to specify the root device here.

1028 This enables support for the Zorro bus in the Amiga. If you have
1029 expansion cards in your Amiga that conform to the Amiga

1093 depends on EXPERIMENTAL && APUS
1095 This option supports the 2232 7-port serial card shipped with the
1096 Amiga 2000 and other Zorro-bus machines, dating from 1989. At
1097 a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
1098 each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
1099 ports were connected with 8 pin DIN connectors on the card bracket,
1100 for which 8 pin to DB25 adapters were supplied. The card also had
1101 jumpers internally to toggle various pinning configurations.
1103 This driver can be built as a module; but then "generic_serial"
1104 will also be built as a module. This has to be loaded before

1147 bool "Enable seccomp to safely compute untrusted bytecode"
1151 This kernel feature is useful for number crunching applications
1152 that may need to compute untrusted bytecode during their
1153 execution. By using pipes or other transports made available to
1154 the process as file descriptors supporting the read/write
1155 syscalls, it's possible to isolate those applications in
1156 their own address space using seccomp. Once seccomp is
1157 enabled via /proc/<pid>/seccomp, it cannot be disabled
1158 and the task is only allowed to execute a few safe syscalls
1159 defined by each seccomp mode.
