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.
83 bool "POWER4 and 970 (G5)"
109 depends on 44x || E500
111 default y if E500 && PHYS_64BIT
114 bool 'Large physical address support' if E500
115 depends on 44x || E500
118 This option enables kernel support for larger than 32-bit physical
119 addresses. This features is not be available on all e500 cores.
121 If in doubt, say N here.
124 bool "AltiVec Support"
125 depends on 6xx || POWER4
126 depends on !8260 && !83xx
128 This option enables kernel support for the Altivec extensions to the
129 PowerPC processor. The kernel currently supports saving and restoring
130 altivec registers, and turning on the 'altivec enable' bit so user
131 processes can execute altivec instructions.
133 This option is only usefully if you have a processor that supports
134 altivec (G4, otherwise known as 74xx series), but does not have
135 any affect on a non-altivec cpu (it does, however add code to the
138 If in doubt, say Y here.
144 This option enables kernel support for the Signal Processing
145 Extensions (SPE) to the PowerPC processor. The kernel currently
146 supports saving and restoring SPE registers, and turning on the
147 'spe enable' bit so user processes can execute SPE instructions.
149 This option is only usefully if you have a processor that supports
150 SPE (e500, otherwise known as 85xx series), but does not have any
151 affect on a non-spe cpu (it does, however add code to the kernel).
153 If in doubt, say Y here.
156 bool "Thermal Management Support"
157 depends on 6xx && !8260 && !83xx
159 G3 and G4 processors have an on-chip temperature sensor called the
160 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
161 temperature within 2-4 degrees Celsius. This option shows the current
162 on-die temperature in /proc/cpuinfo if the cpu supports it.
164 Unfortunately, on some chip revisions, this sensor is very inaccurate
165 and in some cases, does not work at all, so don't assume the cpu
166 temp is actually what /proc/cpuinfo says it is.
169 bool "Interrupt driven TAU driver (DANGEROUS)"
172 The TAU supports an interrupt driven mode which causes an interrupt
173 whenever the temperature goes out of range. This is the fastest way
174 to get notified the temp has exceeded a range. With this option off,
175 a timer is used to re-check the temperature periodically.
177 However, on some cpus it appears that the TAU interrupt hardware
178 is buggy and can cause a situation which would lead unexplained hard
181 Unless you are extending the TAU driver, or enjoy kernel/hardware
182 debugging, leave this option off.
185 bool "Average high and low temp"
188 The TAU hardware can compare the temperature to an upper and lower
189 bound. The default behavior is to show both the upper and lower
190 bound in /proc/cpuinfo. If the range is large, the temperature is
191 either changing a lot, or the TAU hardware is broken (likely on some
192 G4's). If the range is small (around 4 degrees), the temperature is
193 relatively stable. If you say Y here, a single temperature value,
194 halfway between the upper and lower bounds, will be reported in
197 If in doubt, say N here.
199 config MATH_EMULATION
200 bool "Math emulation"
201 depends on 4xx || 8xx || E500
203 Some PowerPC chips designed for embedded applications do not have
204 a floating-point unit and therefore do not implement the
205 floating-point instructions in the PowerPC instruction set. If you
206 say Y here, the kernel will include code to emulate a floating-point
207 unit, which will allow programs that use floating-point
210 If you have an Apple machine or an IBM RS/6000 or pSeries machine,
211 or any machine with a 6xx, 7xx or 7xxx series processor, say N
212 here. Saying Y here will not hurt performance (on any machine) but
213 will increase the size of the kernel.

218 bool "Support for Apple PowerBooks"
219 depends on CPU_FREQ && ADB_PMU
220 select CPU_FREQ_TABLE
222 This adds support for frequency switching on Apple PowerBooks,

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

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

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

1035 This option supports the 2232 7-port serial card shipped with the
1036 Amiga 2000 and other Zorro-bus machines, dating from 1989. At
1037 a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
1038 each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
1039 ports were connected with 8 pin DIN connectors on the card bracket,
1040 for which 8 pin to DB25 adapters were supplied. The card also had
1041 jumpers internally to toggle various pinning configurations.
1043 This driver can be built as a module; but then "generic_serial"
1044 will also be built as a module. This has to be loaded before
