47 prompt "Processor Type"
51 bool "6xx/7xx/74xx/52xx/8260"
53 There are four types of PowerPC chips supported. The more common
54 types (601, 603, 604, 740, 750, 7400), the Motorola embedded
55 versions (821, 823, 850, 855, 860, 52xx, 8260), the IBM embedded
56 versions (403 and 405) and the high end 64 bit Power processors
57 (POWER 3, POWER4, and IBM 970 also known as G5)
58 Unless you are building a kernel for one of the embedded processor
59 systems, 64 bit IBM RS/6000 or an Apple G5, choose 6xx.
60 Note that the kernel runs in 32-bit mode even on 64-bit chips.
61 Also note that because the 52xx & 82xx family has a 603e core,
62 specific support for that chipset is asked later on.
74 bool "POWER4 and 970 (G5)"
101 bool "AltiVec Support"
102 depends on 6xx || POWER4
105 This option enables kernel support for the Altivec extensions to the
106 PowerPC processor. The kernel currently supports saving and restoring
107 altivec registers, and turning on the 'altivec enable' bit so user
108 processes can execute altivec instructions.
110 This option is only usefully if you have a processor that supports
111 altivec (G4, otherwise known as 74xx series), but does not have
112 any affect on a non-altivec cpu (it does, however add code to the
115 If in doubt, say Y here.
121 This option enables kernel support for the Signal Processing
122 Extensions (SPE) to the PowerPC processor. The kernel currently
123 supports saving and restoring SPE registers, and turning on the
124 'spe enable' bit so user processes can execute SPE instructions.
126 This option is only usefully if you have a processor that supports
127 SPE (e500, otherwise known as 85xx series), but does not have any
128 affect on a non-spe cpu (it does, however add code to the kernel).
130 If in doubt, say Y here.
133 bool "Thermal Management Support"
134 depends on 6xx && !8260
136 G3 and G4 processors have an on-chip temperature sensor called the
137 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
138 temperature within 2-4 degrees Celsius. This option shows the current
139 on-die temperature in /proc/cpuinfo if the cpu supports it.
141 Unfortunately, on some chip revisions, this sensor is very inaccurate
142 and in some cases, does not work at all, so don't assume the cpu
143 temp is actually what /proc/cpuinfo says it is.
146 bool "Interrupt driven TAU driver (DANGEROUS)"
149 The TAU supports an interrupt driven mode which causes an interrupt
150 whenever the temperature goes out of range. This is the fastest way
151 to get notified the temp has exceeded a range. With this option off,
152 a timer is used to re-check the temperature periodically.
154 However, on some cpus it appears that the TAU interrupt hardware
155 is buggy and can cause a situation which would lead unexplained hard
158 Unless you are extending the TAU driver, or enjoy kernel/hardware
159 debugging, leave this option off.
162 bool "Average high and low temp"
165 The TAU hardware can compare the temperature to an upper and lower
166 bound. The default behavior is to show both the upper and lower
167 bound in /proc/cpuinfo. If the range is large, the temperature is
168 either changing a lot, or the TAU hardware is broken (likely on some
169 G4's). If the range is small (around 4 degrees), the temperature is
170 relatively stable. If you say Y here, a single temperature value,
171 halfway between the upper and lower bounds, will be reported in
174 If in doubt, say N here.
176 config MATH_EMULATION
177 bool "Math emulation"
178 depends on 4xx || 8xx || E500
180 Some PowerPC chips designed for embedded applications do not have
181 a floating-point unit and therefore do not implement the
182 floating-point instructions in the PowerPC instruction set. If you
183 say Y here, the kernel will include code to emulate a floating-point
184 unit, which will allow programs that use floating-point
187 If you have an Apple machine or an IBM RS/6000 or pSeries machine,
188 or any machine with a 6xx, 7xx or 7xxx series processor, say N
189 here. Saying Y here will not hurt performance (on any machine) but
190 will increase the size of the kernel.
193 bool "kexec system call (EXPERIMENTAL)"
194 depends on EXPERIMENTAL
196 kexec is a system call that implements the ability to shutdown your
197 current kernel, and to start another kernel. It is like a reboot
198 but it is indepedent of the system firmware. And like a reboot
199 you can start any kernel with it, not just Linux.
201 The name comes from the similiarity to the exec system call.
203 It is an ongoing process to be certain the hardware in a machine
204 is properly shutdown, so do not be surprised if this code does not
205 initially work for you. It may help to enable device hotplugging
206 support. As of this writing the exact hardware interface is
207 strongly in flux, so no good recommendation can be made.
209 In the GameCube implementation, kexec allows you to load and
210 run DOL files, including kernel and homebrew DOLs.

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

778 support SMP machines with 603/603e/603ev or PPC750 ("G3") processors
779 since they have inadequate hardware support for multiprocessor
782 If you say N here, the kernel will run on single and multiprocessor
783 machines, but will use only one CPU of a multiprocessor machine. If

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

946 ports were connected with 8 pin DIN connectors on the card bracket,
947 for which 8 pin to DB25 adapters were supplied. The card also had
948 jumpers internally to toggle various pinning configurations.
950 This driver can be built as a module; but then "generic_serial"
951 will also be built as a module. This has to be loaded before
