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 embedded
62 versions (403 and 405) and the high end 64 bit Power processors
63 (POWER 3, POWER4, and IBM 970 also known as G5)
64 Unless you are building a kernel for one of the embedded processor
65 systems, 64 bit IBM RS/6000 or an Apple G5, 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.

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

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

266 CPUs at runtime on SMP machines.

964 Firmware. If unsure, say Y here.
967 bool "Support for PReP Residual Data"
970 Some PReP systems have residual data passed to the kernel by the
971 firmware. This allows detection of memory size, devices present and
972 other useful pieces of information. Sometimes this information is
973 not present or incorrect, in which case it could lead to the machine
974 behaving incorrectly. If this happens, either disable PREP_RESIDUAL
975 or pass the 'noresidual' option to the kernel.
977 If you are running a PReP system, say Y here, otherwise say N.
979 config PROC_PREPRESIDUAL
980 bool "Support for reading of PReP Residual Data in /proc"
981 depends on PREP_RESIDUAL && PROC_FS
983 Enabling this option will create a /proc/residual file which allows
984 you to get at the residual data on PReP systems. You will need a tool
985 (lsresidual) to parse it. If you aren't on a PReP system, you don't

994 default "console=ttyS0,9600 console=tty0 root=/dev/sda2"
996 On some platforms, there is currently no way for the boot loader to
997 pass arguments to the kernel. For these platforms, you can supply
998 some command-line options at build time by entering them here. In
999 most cases you will need to specify the root device here.
1006 This option enables support for the Amiga series of computers.
1013 This enables support for the Zorro bus in the Amiga. If you have
1014 expansion cards in your Amiga that conform to the Amiga
1015 AutoConfig(tm) specification, say Y, otherwise N. Note that even
1016 expansion cards that do not fit in the Zorro slots but fit in e.g.
1017 the CPU slot may fall in this category, so you have to say Y to let

1077 tristate "Commodore A2232 serial support (EXPERIMENTAL)"
1078 depends on EXPERIMENTAL && APUS
1080 This option supports the 2232 7-port serial card shipped with the
1081 Amiga 2000 and other Zorro-bus machines, dating from 1989. At
1082 a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
1083 each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
1084 ports were connected with 8 pin DIN connectors on the card bracket,
1085 for which 8 pin to DB25 adapters were supplied. The card also had
1086 jumpers internally to toggle various pinning configurations.
1088 This driver can be built as a module; but then "generic_serial"
1089 will also be built as a module. This has to be loaded before
1090 "ser_a2232". If you want to do this, answer M here.

1132 bool "Enable seccomp to safely compute untrusted bytecode"
1136 This kernel feature is useful for number crunching applications
1137 that may need to compute untrusted bytecode during their
1138 execution. By using pipes or other transports made available to
1139 the process as file descriptors supporting the read/write
1140 syscalls, it's possible to isolate those applications in
1141 their own address space using seccomp. Once seccomp is
1142 enabled via /proc/<pid>/seccomp, it cannot be disabled
1143 and the task is only allowed to execute a few safe syscalls
1144 defined by each seccomp mode.
