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

210 bool "Support for Apple PowerBooks"
211 depends on CPU_FREQ && ADB_PMU
212 select CPU_FREQ_TABLE
214 This adds support for frequency switching on Apple PowerBooks,

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

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

893 This option reduces the latency of the kernel when reacting to

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

928 depends on PREP_RESIDUAL && PROC_FS
930 Enabling this option will create a /proc/residual file which allows

1027 This option supports the 2232 7-port serial card shipped with the
1028 Amiga 2000 and other Zorro-bus machines, dating from 1989. At
1029 a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
1030 each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
1031 ports were connected with 8 pin DIN connectors on the card bracket,
1032 for which 8 pin to DB25 adapters were supplied. The card also had
1033 jumpers internally to toggle various pinning configurations.
1035 This driver can be built as a module; but then "generic_serial"
1036 will also be built as a module. This has to be loaded before
