300 support SMP machines with 603/603e/603ev or PPC750 ("G3") processors
301 since they have inadequate hardware support for multiprocessor
302 operation.

532 Some versions of the PPC601 (the first PowerPC chip) have bugs which
533 mean that extra synchronization instructions are required near
534 certain instructions, typically those that make major changes to the
535 CPU state. These extra instructions reduce performance slightly.
536 If you say N here, these extra instructions will not be included,

546 G3 and G4 processors have an on-chip temperature sensor called the
547 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
548 temperature within 2-4 degrees Celsius. This option shows the current
549 on-die temperature in /proc/cpuinfo if the cpu supports it.
551 Unfortunately, on some chip revisions, this sensor is very inaccurate
552 and in many cases, does not work at all, so don't assume the cpu
553 temp is actually what /proc/cpuinfo says it is.
555 config TAU_INT
556 bool "Interrupt driven TAU driver (DANGEROUS)"

558 ---help---
559 The TAU supports an interrupt driven mode which causes an interrupt
560 whenever the temperature goes out of range. This is the fastest way
561 to get notified the temp has exceeded a range. With this option off,
562 a timer is used to re-check the temperature periodically.
564 However, on some cpus it appears that the TAU interrupt hardware
565 is buggy and can cause a situation which would lead unexplained hard
566 lockups.
568 Unless you are extending the TAU driver, or enjoy kernel/hardware
569 debugging, leave this option off.

575 The TAU hardware can compare the temperature to an upper and lower
576 bound. The default behavior is to show both the upper and lower
577 bound in /proc/cpuinfo. If the range is large, the temperature is
578 either changing a lot, or the TAU hardware is broken (likely on some
579 G4's). If the range is small (around 4 degrees), the temperature is
580 relatively stable. If you say Y here, a single temperature value,
581 halfway between the upper and lower bounds, will be reported in

803 This kernel feature is useful for number crunching applications
804 that may need to compute untrusted bytecode during their
805 execution. By using pipes or other transports made available to
806 the process as file descriptors supporting the read/write
807 syscalls, it's possible to isolate those applications in
808 their own address space using seccomp. Once seccomp is
809 enabled via /proc/<pid>/seccomp, it cannot be disabled
810 and the task is only allowed to execute a few safe syscalls
811 defined by each seccomp mode.
