51 prompt "Processor Type"
55 bool "6xx/7xx/74xx/52xx/8260"
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, 8260), 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 family has a 603e core,
66 specific support for that chipset is asked later on.
78 bool "POWER4 and 970 (G5)"
110 bool "AltiVec Support"
111 depends on 6xx || POWER4
114 This option enables kernel support for the Altivec extensions to the
115 PowerPC processor. The kernel currently supports saving and restoring
116 altivec registers, and turning on the 'altivec enable' bit so user
117 processes can execute altivec instructions.
119 This option is only usefully if you have a processor that supports
120 altivec (G4, otherwise known as 74xx series), but does not have
121 any affect on a non-altivec cpu (it does, however add code to the
124 If in doubt, say Y here.
130 This option enables kernel support for the Signal Processing
131 Extensions (SPE) to the PowerPC processor. The kernel currently
132 supports saving and restoring SPE registers, and turning on the
133 'spe enable' bit so user processes can execute SPE instructions.
135 This option is only usefully if you have a processor that supports
136 SPE (e500, otherwise known as 85xx series), but does not have any
137 affect on a non-spe cpu (it does, however add code to the kernel).
139 If in doubt, say Y here.
142 bool "Thermal Management Support"
143 depends on 6xx && !8260
145 G3 and G4 processors have an on-chip temperature sensor called the
146 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
147 temperature within 2-4 degrees Celsius. This option shows the current
148 on-die temperature in /proc/cpuinfo if the cpu supports it.
150 Unfortunately, on some chip revisions, this sensor is very inaccurate
151 and in some cases, does not work at all, so don't assume the cpu
152 temp is actually what /proc/cpuinfo says it is.
155 bool "Interrupt driven TAU driver (DANGEROUS)"
158 The TAU supports an interrupt driven mode which causes an interrupt
159 whenever the temperature goes out of range. This is the fastest way
160 to get notified the temp has exceeded a range. With this option off,
161 a timer is used to re-check the temperature periodically.
163 However, on some cpus it appears that the TAU interrupt hardware
164 is buggy and can cause a situation which would lead unexplained hard
167 Unless you are extending the TAU driver, or enjoy kernel/hardware
168 debugging, leave this option off.
171 bool "Average high and low temp"
174 The TAU hardware can compare the temperature to an upper and lower
175 bound. The default behavior is to show both the upper and lower
176 bound in /proc/cpuinfo. If the range is large, the temperature is
177 either changing a lot, or the TAU hardware is broken (likely on some
178 G4's). If the range is small (around 4 degrees), the temperature is
179 relatively stable. If you say Y here, a single temperature value,
180 halfway between the upper and lower bounds, will be reported in
183 If in doubt, say N here.
185 config MATH_EMULATION
186 bool "Math emulation"
187 depends on 4xx || 8xx || E500
189 Some PowerPC chips designed for embedded applications do not have
190 a floating-point unit and therefore do not implement the
191 floating-point instructions in the PowerPC instruction set. If you
192 say Y here, the kernel will include code to emulate a floating-point
193 unit, which will allow programs that use floating-point
196 If you have an Apple machine or an IBM RS/6000 or pSeries machine,
197 or any machine with a 6xx, 7xx or 7xxx series processor, say N
198 here. Saying Y here will not hurt performance (on any machine) but
199 will increase the size of the kernel.

204 bool "Support for Apple PowerBooks"
205 depends on CPU_FREQ && ADB_PMU

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

838 support SMP machines with 603/603e/603ev or PPC750 ("G3") processors
839 since they have inadequate hardware support for multiprocessor
842 If you say N here, the kernel will run on single and multiprocessor
843 machines, but will use only one CPU of a multiprocessor machine. If
844 you say Y here, the kernel will run on single-processor machines.

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

999 tristate "Commodore A2232 serial support (EXPERIMENTAL)"
1000 depends on EXPERIMENTAL && APUS
1002 This option supports the 2232 7-port serial card shipped with the
1003 Amiga 2000 and other Zorro-bus machines, dating from 1989. At
1004 a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
1005 each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
1006 ports were connected with 8 pin DIN connectors on the card bracket,
1007 for which 8 pin to DB25 adapters were supplied. The card also had
1008 jumpers internally to toggle various pinning configurations.
1010 This driver can be built as a module; but then "generic_serial"
1011 will also be built as a module. This has to be loaded before
1012 "ser_a2232". If you want to do this, answer M here.
