59 bool "6xx/7xx/74xx/52xx/82xx/83xx"
62 There are four types of PowerPC chips supported. The more common
63 types (601, 603, 604, 740, 750, 7400), the Motorola embedded
64 versions (821, 823, 850, 855, 860, 52xx, 82xx, 83xx), the IBM embedded
65 versions (403 and 405) and the high end 64 bit Power processors
66 (POWER 3, POWER4, and IBM 970 also known as G5)
67 Unless you are building a kernel for one of the embedded processor
68 systems, 64 bit IBM RS/6000 or an Apple G5, choose 6xx.
69 Note that the kernel runs in 32-bit mode even on 64-bit chips.
70 Also note that because the 52xx, 82xx, & 83xx family has a 603e core,
71 specific support for that chipset is asked later on.
85 bool "POWER4 and 970 (G5)"
111 depends on 44x || E500
113 default y if E500 && PHYS_64BIT
116 bool 'Large physical address support' if E500
117 depends on 44x || E500
120 This option enables kernel support for larger than 32-bit physical
121 addresses. This features is not be available on all e500 cores.
123 If in doubt, say N here.
126 bool "AltiVec Support"
127 depends on 6xx || POWER4
128 depends on !8260 && !83xx
130 This option enables kernel support for the Altivec extensions to the
131 PowerPC processor. The kernel currently supports saving and restoring
132 altivec registers, and turning on the 'altivec enable' bit so user
133 processes can execute altivec instructions.
135 This option is only usefully if you have a processor that supports
136 altivec (G4, otherwise known as 74xx series), but does not have
137 any affect on a non-altivec cpu (it does, however add code to the
140 If in doubt, say Y here.
146 This option enables kernel support for the Signal Processing
147 Extensions (SPE) to the PowerPC processor. The kernel currently
148 supports saving and restoring SPE registers, and turning on the
149 'spe enable' bit so user processes can execute SPE instructions.
151 This option is only usefully if you have a processor that supports
152 SPE (e500, otherwise known as 85xx series), but does not have any
153 affect on a non-spe cpu (it does, however add code to the kernel).
155 If in doubt, say Y here.
158 bool "Thermal Management Support"
159 depends on 6xx && !8260 && !83xx
161 G3 and G4 processors have an on-chip temperature sensor called the
162 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
163 temperature within 2-4 degrees Celsius. This option shows the current
164 on-die temperature in /proc/cpuinfo if the cpu supports it.
166 Unfortunately, on some chip revisions, this sensor is very inaccurate
167 and in some cases, does not work at all, so don't assume the cpu
168 temp is actually what /proc/cpuinfo says it is.
171 bool "Interrupt driven TAU driver (DANGEROUS)"
174 The TAU supports an interrupt driven mode which causes an interrupt
175 whenever the temperature goes out of range. This is the fastest way
176 to get notified the temp has exceeded a range. With this option off,
177 a timer is used to re-check the temperature periodically.
179 However, on some cpus it appears that the TAU interrupt hardware
180 is buggy and can cause a situation which would lead unexplained hard
183 Unless you are extending the TAU driver, or enjoy kernel/hardware
184 debugging, leave this option off.
187 bool "Average high and low temp"
190 The TAU hardware can compare the temperature to an upper and lower
191 bound. The default behavior is to show both the upper and lower
192 bound in /proc/cpuinfo. If the range is large, the temperature is
193 either changing a lot, or the TAU hardware is broken (likely on some
194 G4's). If the range is small (around 4 degrees), the temperature is
195 relatively stable. If you say Y here, a single temperature value,
196 halfway between the upper and lower bounds, will be reported in
199 If in doubt, say N here.
201 config MATH_EMULATION
202 bool "Math emulation"
203 depends on 4xx || 8xx || E500
205 Some PowerPC chips designed for embedded applications do not have
206 a floating-point unit and therefore do not implement the
207 floating-point instructions in the PowerPC instruction set. If you
208 say Y here, the kernel will include code to emulate a floating-point
209 unit, which will allow programs that use floating-point
212 If you have an Apple machine or an IBM RS/6000 or pSeries machine,
213 or any machine with a 6xx, 7xx or 7xxx series processor, say N
214 here. Saying Y here will not hurt performance (on any machine) but
215 will increase the size of the kernel.

220 bool "Support for Apple PowerBooks"

224 This adds support for frequency switching on Apple PowerBooks,

228 config PPC601_SYNC_FIX
229 bool "Workarounds for PPC601 bugs"
230 depends on 6xx && (PPC_PREP || PPC_PMAC)
232 Some versions of the PPC601 (the first PowerPC chip) have bugs which
233 mean that extra synchronization instructions are required near
234 certain instructions, typically those that make major changes to the
235 CPU state. These extra instructions reduce performance slightly.
236 If you say N here, these extra instructions will not be included,
237 resulting in a kernel which will run faster but may not run at all
238 on some systems with the PPC601 chip.
240 If in doubt, say Y here.

872 than one CPU, say Y. Note that the kernel does not currently
873 support SMP machines with 603/603e/603ev or PPC750 ("G3") processors
874 since they have inadequate hardware support for multiprocessor
877 If you say N here, the kernel will run on single and multiprocessor
878 machines, but will use only one CPU of a multiprocessor machine. If
879 you say Y here, the kernel will run on single-processor machines.
880 On a single-processor machine, the kernel will run faster if you say
883 If you don't know what to do here, say N.
886 bool "Distribute interrupts on all CPUs by default"
889 This option gives the kernel permission to distribute IRQs across

924 bool "Support for PReP Residual Data"
927 Some PReP systems have residual data passed to the kernel by the
928 firmware. This allows detection of memory size, devices present and
929 other useful pieces of information. Sometimes this information is
930 not present or incorrect, in which case it could lead to the machine
931 behaving incorrectly. If this happens, either disable PREP_RESIDUAL
932 or pass the 'noresidual' option to the kernel.

970 This enables support for the Zorro bus in the Amiga. If you have
971 expansion cards in your Amiga that conform to the Amiga
972 AutoConfig(tm) specification, say Y, otherwise N. Note that even
973 expansion cards that do not fit in the Zorro slots but fit in e.g.

1035 depends on EXPERIMENTAL && APUS
1037 This option supports the 2232 7-port serial card shipped with the
1038 Amiga 2000 and other Zorro-bus machines, dating from 1989. At
1039 a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
1040 each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
1041 ports were connected with 8 pin DIN connectors on the card bracket,
1042 for which 8 pin to DB25 adapters were supplied. The card also had
1043 jumpers internally to toggle various pinning configurations.
1045 This driver can be built as a module; but then "generic_serial"
1046 will also be built as a module. This has to be loaded before

1091 This kernel feature is useful for number crunching applications
1092 that may need to compute untrusted bytecode during their
1093 execution. By using pipes or other transports made available to
1094 the process as file descriptors supporting the read/write
1095 syscalls, it's possible to isolate those applications in
1096 their own address space using seccomp. Once seccomp is
1097 enabled via /proc/<pid>/seccomp, it cannot be disabled
1098 and the task is only allowed to execute a few safe syscalls
1099 defined by each seccomp mode.
