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

214 bool "Support for Apple PowerBooks"
215 depends on CPU_FREQ && ADB_PMU

218 This adds support for frequency switching on Apple PowerBooks,

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

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

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

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

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

1029 depends on EXPERIMENTAL && APUS
1031 This option supports the 2232 7-port serial card shipped with the
1032 Amiga 2000 and other Zorro-bus machines, dating from 1989. At
1033 a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
1034 each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
1035 ports were connected with 8 pin DIN connectors on the card bracket,
1036 for which 8 pin to DB25 adapters were supplied. The card also had
1037 jumpers internally to toggle various pinning configurations.
1039 This driver can be built as a module; but then "generic_serial"
1040 will also be built as a module. This has to be loaded before
