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).
124
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.

600 G3 and G4 processors have an on-chip temperature sensor called the

602 temperature within 2-4 degrees Celsius. This option shows the current
603 on-die temperature in /proc/cpuinfo if the cpu supports it.
604
605 Unfortunately, on some chip revisions, this sensor is very inaccurate

613 The TAU supports an interrupt driven mode which causes an interrupt
614 whenever the temperature goes out of range. This is the fastest way
615 to get notified the temp has exceeded a range. With this option off,
616 a timer is used to re-check the temperature periodically.
617
618 However, on some cpus it appears that the TAU interrupt hardware
619 is buggy and can cause a situation which would lead unexplained hard
620 lockups.

622 Unless you are extending the TAU driver, or enjoy kernel/hardware
623 debugging, leave this option off.

629 The TAU hardware can compare the temperature to an upper and lower

631 bound in /proc/cpuinfo. If the range is large, the temperature is
632 either changing a lot, or the TAU hardware is broken (likely on some
633 G4's). If the range is small (around 4 degrees), the temperature is
634 relatively stable. If you say Y here, a single temperature value,
635 halfway between the upper and lower bounds, will be reported in
636 /proc/cpuinfo.
637
638 If in doubt, say N here.

850 help
851 This kernel feature is useful for number crunching applications
852 that may need to compute untrusted bytecode during their
853 execution. By using pipes or other transports made available to
854 the process as file descriptors supporting the read/write
855 syscalls, it's possible to isolate those applications in
856 their own address space using seccomp. Once seccomp is
857 enabled via /proc/<pid>/seccomp, it cannot be disabled
858 and the task is only allowed to execute a few safe syscalls
859 defined by each seccomp mode.
