34 The PowerPC is a modern RISC architecture descended from the POWER
35 architecture designed by IBM. The PowerPC architecture is designed
36 to allow high-speed implementations which can execute several
37 instructions in each clock cycle. IBM and Motorola design and
38 manufacture PowerPC processors aimed at embedded, desktop and server
39 applications. PowerPC chips are used in Apple Power Macintoshes
40 (including iMacs, iBooks and PowerBooks), in IBM pSeries (RS/6000)
41 and iSeries (AS/400) machines, and in a broad range of embedded
42 applications. The Linux PowerPC port has a home page at

50 prompt "Processor Type"
54 bool "6xx/7xx/74xx/8260"
56 There are four types of PowerPC chips supported. The more common
57 types (601, 603, 604, 740, 750, 7400), the Motorola embedded
58 versions (821, 823, 850, 855, 860, 8260), the IBM embedded versions
59 (403 and 405) and the high end 64 bit Power processors (POWER 3)
60 Unless you are building a kernel for one of the embedded processor
61 systems, or a 64 bit IBM RS/6000, choose 6xx. Note that the kernel
62 runs in 32-bit mode even on 64-bit chips. Also note that because

548 bool "Symmetric multi-processing support"
550 This enables support for systems with more than one CPU. If you have
551 a system with only one CPU, say N. If you have a system with more
552 than one CPU, say Y. Note that the kernel does not currently
553 support SMP machines with 603/603e/603ev or PPC750 ("G3") processors
554 since they have inadequate hardware support for multiprocessor
557 If you say N here, the kernel will run on single and multiprocessor
558 machines, but will use only one CPU of a multiprocessor machine. If
559 you say Y here, the kernel will run on single-processor machines.
560 On a single-processor machine, the kernel will run faster if you say
563 If you don't know what to do here, say N.
566 bool "Distribute interrupts on all CPUs by default"
569 This option gives the kernel permission to distribute IRQs across
570 multiple CPUs. Saying N here will route all IRQs to the first
571 CPU. Generally saying Y is safe, although some problems have been
572 reported with SMP Power Macintoshes with this option enabled.
575 int "Maximum number of CPUs (2-32)"
580 bool "Preemptible Kernel"
583 This option reduces the latency of the kernel when reacting to
584 real-time or interactive events by allowing a low priority process to
585 be preempted even if it is in kernel mode executing a system call.
586 Unfortunately the kernel code has some race conditions if both
587 CONFIG_SMP and CONFIG_PREEMPT are enabled, so this option is
588 currently disabled if you are building an SMP kernel.
590 Say Y here if you are building a kernel for a desktop, embedded
591 or real-time system. Say N if you are unsure.
594 bool "AltiVec Support"
595 depends on 6xx && !8260
597 This option enables kernel support for the Altivec extensions to the
598 PowerPC processor. The kernel currently supports saving and restoring
599 altivec registers, and turning on the 'altivec enable' bit so user
600 processes can execute altivec instructions.
602 This option is only usefully if you have a processor that supports
603 altivec (G4, otherwise known as 74xx series), but does not have
604 any affect on a non-altivec cpu (it does, however add code to the
607 If in doubt, say Y here.
610 bool "Thermal Management Support"
611 depends on 6xx && !8260
613 G3 and G4 processors have an on-chip temperature sensor called the
614 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
615 temperature within 2-4 degrees Celsius. This option shows the current
616 on-die temperature in /proc/cpuinfo if the cpu supports it.
618 Unfortunately, on some chip revisions, this sensor is very inaccurate
619 and in some cases, does not work at all, so don't assume the cpu
620 temp is actually what /proc/cpuinfo says it is.
623 bool "Interrupt driven TAU driver (DANGEROUS)"
626 The TAU supports an interrupt driven mode which causes an interrupt
627 whenever the temperature goes out of range. This is the fastest way
628 to get notified the temp has exceeded a range. With this option off,
629 a timer is used to re-check the temperature periodically.
631 However, on some cpus it appears that the TAU interrupt hardware
632 is buggy and can cause a situation which would lead unexplained hard
635 Unless you are extending the TAU driver, or enjoy kernel/hardware
636 debugging, leave this option off.
639 bool "Average high and low temp"
642 The TAU hardware can compare the temperature to an upper and lower
643 bound. The default behavior is to show both the upper and lower
644 bound in /proc/cpuinfo. If the range is large, the temperature is
645 either changing a lot, or the TAU hardware is broken (likely on some
646 G4's). If the range is small (around 4 degrees), the temperature is
647 relatively stable. If you say Y here, a single temperature value,
648 halfway between the upper and lower bounds, will be reported in
651 If in doubt, say N here.
653 config MATH_EMULATION
654 bool "Math emulation"
655 depends on 4xx || 8xx
657 Some PowerPC chips designed for embedded applications do not have
658 a floating-point unit and therefore do not implement the
659 floating-point instructions in the PowerPC instruction set. If you
660 say Y here, the kernel will include code to emulate a floating-point
661 unit, which will allow programs that use floating-point
664 If you have an Apple machine or an IBM RS/6000 or pSeries machine,
665 or any machine with a 6xx, 7xx or 7xxx series processor, say N
666 here. Saying Y here will not hurt performance (on any machine) but
667 will increase the size of the kernel.
670 bool "CPU Frequency scaling"
672 Clock scaling allows you to change the clock speed of CPUs on the
673 fly. This is a nice method to save battery power on notebooks,
674 because the lower the clock speed, the less power the CPU consumes.

685 This enables the /proc/cpufreq interface for controlling

687 interface instead (which is built automatically).
689 For details, take a look at linux/Documentation/cpufreq.
693 config CPU_FREQ_24_API
694 bool "/proc/sys/cpu/ interface (2.4. / OLD)"
697 This enables the /proc/sys/cpu/ sysctl interface for controlling
698 CPUFreq, as known from the 2.4.-kernel patches for CPUFreq. 2.5
699 uses a sysfs interface instead. Please note that some drivers do
700 not work well with the 2.4. /proc/sys/cpu sysctl interface,
701 so if in doubt, say N here.
703 For details, take a look at linux/Documentation/cpufreq.
708 bool "Support for Apple PowerBooks"
709 depends on CPU_FREQ && ADB_PMU
711 This adds support for frequency switching on Apple PowerBooks,
712 this currently includes some models of iBook & Titanium
720 bool "High memory support"
723 bool "Support for ISA-bus hardware"
726 Find out whether you have ISA slots on your motherboard. ISA is the
727 name of a bus system, i.e. the way the CPU talks to the other stuff
728 inside your box. If you have an Apple machine, say N here; if you
729 have an IBM RS/6000 or pSeries machine or a PReP machine, say Y. If
730 you have an embedded board, consult your board documentation.
735 The Extended Industry Standard Architecture (EISA) bus is a bus
736 architecture used on some older intel-based PCs.
741 # Yes MCA RS/6000s exist but Linux-PPC does not currently support any
745 MicroChannel Architecture is found in some older IBM RS/6000
746 machines. It is a bus system similar to PCI or ISA. MCA-based
747 RS/6000 machines are currently not supported by Linux.

752 default PCI_PERMEDIA if !4xx && !8260 && !8xx && APUS
753 default PCI_QSPAN if !4xx && !8260 && 8xx
755 Find out whether your system includes a PCI bus. PCI is the name of
756 a bus system, i.e. the way the CPU talks to the other stuff inside
757 your box. If you say Y here, the kernel will include drivers and
758 infrastructure code to support PCI bus devices.

773 depends on !4xx && !8xx && APUS
775 # only elf supported, a.out is not -- Cort
781 If you enabled support for /proc file system then the file
782 /proc/kcore will contain the kernel core image in ELF format. This
785 $ cd /usr/src/linux ; gdb vmlinux /proc/kcore
787 This is especially useful if you have compiled the kernel with the
788 "-g" option to preserve debugging information. It is mainly used
789 for examining kernel data structures on the live kernel.
795 ELF (Executable and Linkable Format) is a format for libraries and
796 executables used across different architectures and operating
804 tristate "Kernel support for MISC binaries"
806 If you say Y here, it will be possible to plug wrapper-driven binary
807 formats into the kernel. You will like this especially when you use
808 programs that need an interpreter to run like Java, Python or
809 Emacs-Lisp. It's also useful if you often run DOS executables under
810 the Linux DOS emulator DOSEMU (read the DOSEMU-HOWTO, available from
811 <http://www.tldp.org/docs.html#howto>). Once you have
812 registered such a binary class with the kernel, you can start one of
813 those programs simply by typing in its name at a shell prompt; Linux
814 will automatically feed it to the correct interpreter.
816 You can do other nice things, too. Read the file
817 <file:Documentation/binfmt_misc.txt> to learn how to use this
818 feature, and <file:Documentation/java.txt> for information about how
819 to include Java support.
821 You must say Y to "/proc file system support" (CONFIG_PROC_FS) to
822 use this part of the kernel.
824 You may say M here for module support and later load the module when
825 you have use for it; the module is called binfmt_misc. If you
826 don't know what to answer at this point, say Y.
828 source "drivers/pci/Kconfig"
831 bool "Support for hot-pluggable devices"
833 Say Y here if you want to plug devices into your computer while
834 the system is running, and be able to use them quickly. In many
835 cases, the devices can likewise be unplugged at any time too.
837 One well known example of this is PCMCIA- or PC-cards, credit-card
838 size devices such as network cards, modems or hard drives which are
839 plugged into slots found on all modern laptop computers. Another
840 example, used on modern desktops as well as laptops, is USB.
842 Enable HOTPLUG and KMOD, and build a modular kernel. Get agent
843 software (at <http://linux-hotplug.sourceforge.net/>) and install it.
844 Then your kernel will automatically call out to a user mode "policy
845 agent" (/sbin/hotplug) to load modules and set up software needed
846 to use devices as you hotplug them.

852 config PPC601_SYNC_FIX
853 bool "Workarounds for PPC601 bugs"
854 depends on ALL_PPC && !POWER3
856 Some versions of the PPC601 (the first PowerPC chip) have bugs which
857 mean that extra synchronization instructions are required near
858 certain instructions, typically those that make major changes to the
859 CPU state. These extra instructions reduce performance slightly.
860 If you say N here, these extra instructions will not be included,
861 resulting in a kernel which will run faster but may not run at all
862 on some systems with the PPC601 chip.
864 If in doubt, say Y here.
866 config PROC_DEVICETREE
867 bool "Support for Open Firmware device tree in /proc"
868 depends on ALL_PPC && PROC_FS
870 This option adds a device-tree directory under /proc which contains
871 an image of the device tree that the kernel copies from Open
872 Firmware. If unsure, say Y here.
875 bool "Support for RTAS (RunTime Abstraction Services) in /proc"

1198 Integrated Disk Electronics (IDE aka ATA-1) is a connecting standard
1199 for mass storage units such as hard disks. It was designed by
1200 Western Digital and Compaq Computer in 1984. Quite a number of
1201 disks use the IDE interface.
1203 Fast-IDE is ATA-2 (also named Fast ATA), Enhanced IDE (EIDE) is
1204 ATA-3. It provides support for larger disks (up to 8.4GB by means of
1205 the LBA standard), more disks (4 instead of 2) and for other mass
1206 storage units such as tapes and cdrom. UDMA/33 (aka UltraDMA/33) is
1207 ATA-4 and provides faster (and more CPU friendly) transfer modes
1208 than previous PIO (Programmed processor Input/Output) from previous
1209 ATA/IDE standards by means of fast DMA controllers.
1211 ATA Packet Interface (ATAPI) is a protocol used by EIDE tape and
1212 CD-ROM drives, similar in many respects to the SCSI protocol.
1214 SMART IDE (Self Monitoring, Analysis and Reporting Technology) was
1215 designed in order to prevent data corruption and disk crash by
1216 detecting pre hardware failure conditions (heat, access time, and
1217 the like...). Disks built since June 1995 may follow this standard.
