119 There are four families of PowerPC chips supported. The more common
120 types (601, 603, 604, 740, 750, 7400), the Motorola embedded
121 versions (821, 823, 850, 855, 860, 52xx, 82xx, 83xx), the AMCC
122 embedded versions (403 and 405) and the high end 64 bit Power
123 processors (POWER 3, POWER4, and IBM PPC970 also known as G5).
125 Unless you are building a kernel for one of the embedded processor
126 systems, 64 bit IBM RS/6000 or an Apple G5, choose 6xx.

263 PowerPC processor. The kernel currently supports saving and restoring
264 altivec registers, and turning on the 'altivec enable' bit so user
265 processes can execute altivec instructions.
267 This option is only usefully if you have a processor that supports

281 supports saving and restoring SPE registers, and turning on the
282 'spe enable' bit so user processes can execute SPE instructions.
284 This option is only useful if you have a processor that supports

304 Select this option to enable more accurate task and CPU time
305 accounting. This is done by reading a CPU counter on each
306 kernel entry and exit and on transitions within the kernel
307 between system, softirq and hardirq state, so there is a
308 small performance impact. This also enables accounting of
309 stolen time on logically-partitioned systems running on

318 This enables support for systems with more than one CPU. If you have

320 than one CPU, say Y. Note that the kernel does not currently
321 support SMP machines with 603/603e/603ev or PPC750 ("G3") processors
322 since they have inadequate hardware support for multiprocessor

612 depends on 6xx && (PPC_PREP || PPC_PMAC)
614 Some versions of the PPC601 (the first PowerPC chip) have bugs which
615 mean that extra synchronization instructions are required near
616 certain instructions, typically those that make major changes to the
617 CPU state. These extra instructions reduce performance slightly.
618 If you say N here, these extra instructions will not be included,
619 resulting in a kernel which will run faster but may not run at all
620 on some systems with the PPC601 chip.
622 If in doubt, say Y here.
625 bool "On-chip CPU temperature sensor support"
628 G3 and G4 processors have an on-chip temperature sensor called the
629 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
630 temperature within 2-4 degrees Celsius. This option shows the current
631 on-die temperature in /proc/cpuinfo if the cpu supports it.
633 Unfortunately, on some chip revisions, this sensor is very inaccurate
634 and in many cases, does not work at all, so don't assume the cpu
635 temp is actually what /proc/cpuinfo says it is.
638 bool "Interrupt driven TAU driver (DANGEROUS)"
641 The TAU supports an interrupt driven mode which causes an interrupt
642 whenever the temperature goes out of range. This is the fastest way
643 to get notified the temp has exceeded a range. With this option off,
644 a timer is used to re-check the temperature periodically.
646 However, on some cpus it appears that the TAU interrupt hardware
647 is buggy and can cause a situation which would lead unexplained hard
650 Unless you are extending the TAU driver, or enjoy kernel/hardware
651 debugging, leave this option off.
654 bool "Average high and low temp"
657 The TAU hardware can compare the temperature to an upper and lower
658 bound. The default behavior is to show both the upper and lower
659 bound in /proc/cpuinfo. If the range is large, the temperature is
660 either changing a lot, or the TAU hardware is broken (likely on some
661 G4's). If the range is small (around 4 degrees), the temperature is
662 relatively stable. If you say Y here, a single temperature value,
663 halfway between the upper and lower bounds, will be reported in
666 If in doubt, say N here.

711 bool "Enable IOMMU virtual merging (EXPERIMENTAL)"
712 depends on EXPERIMENTAL && PPC64
715 Cause IO segments sent to a device for DMA to be merged virtually
716 by the IOMMU when they happen to have been allocated contiguously.
717 This doesn't add pressure to the IOMMU allocator. However, some

735 bool "kexec system call (EXPERIMENTAL)"
736 depends on PPC_MULTIPLATFORM && EXPERIMENTAL
738 kexec is a system call that implements the ability to shutdown your
739 current kernel, and to start another kernel. It is like a reboot
740 but it is independent of the system firmware. And like a reboot
741 you can start any kernel with it, not just Linux.
743 The name comes from the similarity to the exec system call.
745 It is an ongoing process to be certain the hardware in a machine
746 is properly shutdown, so do not be surprised if this code does not
747 initially work for you. It may help to enable device hotplugging
748 support. As of this writing the exact hardware interface is
749 strongly in flux, so no good recommendation can be made.

883 syscalls, it's possible to isolate those applications in
884 their own address space using seccomp. Once seccomp is

1097 config CONSISTENT_SIZE_BOOL
1098 bool "Set custom consistent memory pool size"
1099 depends on ADVANCED_OPTIONS && NOT_COHERENT_CACHE
1101 This option allows you to set the size of the
1102 consistent memory pool. This pool of virtual memory
1103 is used to make consistent memory allocations.
1105 config CONSISTENT_SIZE
1106 hex "Size of consistent memory pool" if CONSISTENT_SIZE_BOOL
1107 default "0x00200000" if NOT_COHERENT_CACHE
1109 config BOOT_LOAD_BOOL
1110 bool "Set the boot link/load address"
1111 depends on ADVANCED_OPTIONS && !PPC_MULTIPLATFORM
1113 This option allows you to set the initial load address of the zImage
1114 or zImage.initrd file. This can be useful if you are on a board
1115 which has a small amount of memory.
1117 Say N here unless you know what you are doing.

1159 depends on PPC64 && KALLSYMS && EXPERIMENTAL && MODULES
1161 Kprobes allows you to trap at almost any kernel address and
1162 execute a callback function. register_kprobe() establishes
1163 a probepoint and specifies the callback. Kprobes is useful
1164 for kernel debugging, non-intrusive instrumentation and testing.
1165 If in doubt, say "N".
