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
268 altivec (G4, otherwise known as 74xx series), but does not have

280 Extensions (SPE) to the PowerPC processor. The kernel currently
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
285 SPE (e500, otherwise known as 85xx series), but does not have any

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
319 a system with only one CPU, say N. If you have a system with more
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

326 machines, but will use only one CPU of a multiprocessor machine. If

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

707 bool "Enable IOMMU virtual merging (EXPERIMENTAL)"
708 depends on EXPERIMENTAL && PPC64
711 Cause IO segments sent to a device for DMA to be merged virtually
712 by the IOMMU when they happen to have been allocated contiguously.
713 This doesn't add pressure to the IOMMU allocator. However, some
714 drivers don't support getting large merged segments coming back

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

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

1095 bool "Set custom consistent memory pool size"
1096 depends on ADVANCED_OPTIONS && NOT_COHERENT_CACHE
1098 This option allows you to set the size of the
1099 consistent memory pool. This pool of virtual memory
1100 is used to make consistent memory allocations.

1103 hex "Size of consistent memory pool" if CONSISTENT_SIZE_BOOL

1107 bool "Set the boot link/load address"
1108 depends on ADVANCED_OPTIONS && !PPC_MULTIPLATFORM
1110 This option allows you to set the initial load address of the zImage
1111 or zImage.initrd file. This can be useful if you are on a board
1112 which has a small amount of memory.
1114 Say N here unless you know what you are doing.

1158 Kprobes allows you to trap at almost any kernel address and
1159 execute a callback function. register_kprobe() establishes
1160 a probepoint and specifies the callback. Kprobes is useful
1161 for kernel debugging, non-intrusive instrumentation and testing.
1162 If in doubt, say "N".
