43 prompt "Processor Type"
47 bool "6xx/7xx/74xx/52xx/8260"
49 There are four types of PowerPC chips supported. The more common
50 types (601, 603, 604, 740, 750, 7400), the Motorola embedded
51 versions (821, 823, 850, 855, 860, 52xx, 8260), the IBM embedded
52 versions (403 and 405) and the high end 64 bit Power processors
53 (POWER 3, POWER4, and IBM 970 also known as G5)
54 Unless you are building a kernel for one of the embedded processor
55 systems, 64 bit IBM RS/6000 or an Apple G5, choose 6xx.
56 Note that the kernel runs in 32-bit mode even on 64-bit chips.
57 Also note that because the 52xx & 82xx family has a 603e core,
58 specific support for that chipset is asked later on.
70 bool "POWER4 and 970 (G5)"
96 bool "AltiVec Support"
97 depends on 6xx || POWER4
100 This option enables kernel support for the Altivec extensions to the
101 PowerPC processor. The kernel currently supports saving and restoring
102 altivec registers, and turning on the 'altivec enable' bit so user
103 processes can execute altivec instructions.
105 This option is only usefully if you have a processor that supports
106 altivec (G4, otherwise known as 74xx series), but does not have
107 any affect on a non-altivec cpu (it does, however add code to the
110 If in doubt, say Y here.
116 This option enables kernel support for the Signal Processing
117 Extensions (SPE) to the PowerPC processor. The kernel currently
118 supports saving and restoring SPE registers, and turning on the
119 'spe enable' bit so user processes can execute SPE instructions.
121 This option is only usefully if you have a processor that supports
122 SPE (e500, otherwise known as 85xx series), but does not have any
123 affect on a non-spe cpu (it does, however add code to the kernel).
125 If in doubt, say Y here.
128 bool "Thermal Management Support"
129 depends on 6xx && !8260
131 G3 and G4 processors have an on-chip temperature sensor called the
132 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
133 temperature within 2-4 degrees Celsius. This option shows the current
134 on-die temperature in /proc/cpuinfo if the cpu supports it.
136 Unfortunately, on some chip revisions, this sensor is very inaccurate
137 and in some cases, does not work at all, so don't assume the cpu
138 temp is actually what /proc/cpuinfo says it is.
141 bool "Interrupt driven TAU driver (DANGEROUS)"
144 The TAU supports an interrupt driven mode which causes an interrupt
145 whenever the temperature goes out of range. This is the fastest way
146 to get notified the temp has exceeded a range. With this option off,
147 a timer is used to re-check the temperature periodically.
149 However, on some cpus it appears that the TAU interrupt hardware
150 is buggy and can cause a situation which would lead unexplained hard
153 Unless you are extending the TAU driver, or enjoy kernel/hardware
154 debugging, leave this option off.
157 bool "Average high and low temp"
160 The TAU hardware can compare the temperature to an upper and lower
161 bound. The default behavior is to show both the upper and lower
162 bound in /proc/cpuinfo. If the range is large, the temperature is
163 either changing a lot, or the TAU hardware is broken (likely on some
164 G4's). If the range is small (around 4 degrees), the temperature is
165 relatively stable. If you say Y here, a single temperature value,
166 halfway between the upper and lower bounds, will be reported in
169 If in doubt, say N here.
171 config MATH_EMULATION
172 bool "Math emulation"
173 depends on 4xx || 8xx || E500
175 Some PowerPC chips designed for embedded applications do not have
176 a floating-point unit and therefore do not implement the
177 floating-point instructions in the PowerPC instruction set. If you
178 say Y here, the kernel will include code to emulate a floating-point
179 unit, which will allow programs that use floating-point
182 If you have an Apple machine or an IBM RS/6000 or pSeries machine,
183 or any machine with a 6xx, 7xx or 7xxx series processor, say N
184 here. Saying Y here will not hurt performance (on any machine) but
185 will increase the size of the kernel.
188 bool "CPU Frequency scaling"
190 Clock scaling allows you to change the clock speed of CPUs on the
191 fly. This is a nice method to save battery power on notebooks,
192 because the lower the clock speed, the less power the CPU consumes.

215 bool "Workarounds for PPC601 bugs"
216 depends on 6xx && (PPC_PREP || PPC_PMAC)
218 Some versions of the PPC601 (the first PowerPC chip) have bugs which
219 mean that extra synchronization instructions are required near
220 certain instructions, typically those that make major changes to the
221 CPU state. These extra instructions reduce performance slightly.
222 If you say N here, these extra instructions will not be included,
223 resulting in a kernel which will run faster but may not run at all
224 on some systems with the PPC601 chip.
226 If in doubt, say Y here.

247 bool "kexec system call (EXPERIMENTAL)"
248 depends on EXPERIMENTAL
250 kexec is a system call that implements the ability to shutdown your
251 current kernel, and to start another kernel. It is like a reboot
252 but it is indepedent of the system firmware. And like a reboot
253 you can start any kernel with it, not just Linux.
255 The name comes from the similiarity to the exec system call.
257 It is an ongoing process to be certain the hardware in a machine
258 is properly shutdown, so do not be surprised if this code does not
259 initially work for you. It may help to enable device hotplugging
260 support. As of this writing the exact hardware interface is
261 strongly in flux, so no good recommendation can be made.
263 In the GameCube implementation, kexec allows you to load and
264 run DOL files, including kernel and homebrew DOLs.

794 than one CPU, say Y. Note that the kernel does not currently
795 support SMP machines with 603/603e/603ev or PPC750 ("G3") processors
796 since they have inadequate hardware support for multiprocessor
799 If you say N here, the kernel will run on single and multiprocessor
800 machines, but will use only one CPU of a multiprocessor machine. If

849 Some PReP systems have residual data passed to the kernel by the
850 firmware. This allows detection of memory size, devices present and
851 other useful pieces of information. Sometimes this information is
852 not present or incorrect, in which case it could lead to the machine

959 This option supports the 2232 7-port serial card shipped with the
960 Amiga 2000 and other Zorro-bus machines, dating from 1989. At
961 a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
962 each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
963 ports were connected with 8 pin DIN connectors on the card bracket,
964 for which 8 pin to DB25 adapters were supplied. The card also had
965 jumpers internally to toggle various pinning configurations.
967 This driver can be built as a module; but then "generic_serial"
968 will also be built as a module. This has to be loaded before
969 "ser_a2232". If you want to do this, answer M here.

980 depends on AMIGA_PCMCIA
982 If you have a PCMCIA NE2000 compatible adapter, say Y. Otherwise,
985 To compile this driver as a module, choose M here: the
986 module will be called apne.

993 bool "Use power LED as a heartbeat"
996 Use the power-on LED on your machine as a load meter. The exact
997 behavior is platform-dependent, but normally the flash frequency is
998 a hyperbolic function of the 5-minute load average.

1014 Find out whether you have ISA slots on your motherboard. ISA is the
1015 name of a bus system, i.e. the way the CPU talks to the other stuff
1016 inside your box. If you have an Apple machine, say N here; if you
1017 have an IBM RS/6000 or pSeries machine or a PReP machine, say Y. If
1018 you have an embedded board, consult your board documentation.

1044 Find out whether your system includes a PCI bus. PCI is the name of
1045 a bus system, i.e. the way the CPU talks to the other stuff inside
1046 your box. If you say Y here, the kernel will include drivers and
1047 infrastructure code to support PCI bus devices.

1057 Say Y here if you have a system based on a Motorola 8xx-series
1058 embedded processor with a QSPAN PCI interface, otherwise say N.

1103 This option will enable prompting for a variety of advanced kernel
1104 configuration options. These options can cause the kernel to not
1105 work if they are set incorrectly, but can be used to optimize certain
1106 aspects of kernel memory management.
