390 Some versions of the PPC601 (the first PowerPC chip) have bugs which
391 mean that extra synchronization instructions are required near
392 certain instructions, typically those that make major changes to the
393 CPU state. These extra instructions reduce performance slightly.
394 If you say N here, these extra instructions will not be included,
395 resulting in a kernel which will run faster but may not run at all

400config TAU
401 bool "Thermal Management Support"
402 depends on 6xx
403 help
404 G3 and G4 processors have an on-chip temperature sensor called the
405 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
406 temperature within 2-4 degrees Celsius. This option shows the current
407 on-die temperature in /proc/cpuinfo if the cpu supports it.
408
409 Unfortunately, on some chip revisions, this sensor is very inaccurate
410 and in some cases, does not work at all, so don't assume the cpu
411 temp is actually what /proc/cpuinfo says it is.
412
413config TAU_INT
414 bool "Interrupt driven TAU driver (DANGEROUS)"
415 depends on TAU
416 ---help---
417 The TAU supports an interrupt driven mode which causes an interrupt
418 whenever the temperature goes out of range. This is the fastest way
419 to get notified the temp has exceeded a range. With this option off,
420 a timer is used to re-check the temperature periodically.
421
422 However, on some cpus it appears that the TAU interrupt hardware
423 is buggy and can cause a situation which would lead unexplained hard
424 lockups.
425
426 Unless you are extending the TAU driver, or enjoy kernel/hardware
427 debugging, leave this option off.
428
429config TAU_AVERAGE
430 bool "Average high and low temp"

433 The TAU hardware can compare the temperature to an upper and lower
434 bound. The default behavior is to show both the upper and lower
435 bound in /proc/cpuinfo. If the range is large, the temperature is
436 either changing a lot, or the TAU hardware is broken (likely on some
437 G4's). If the range is small (around 4 degrees), the temperature is
438 relatively stable. If you say Y here, a single temperature value,
439 halfway between the upper and lower bounds, will be reported in
440 /proc/cpuinfo.

504 kexec is a system call that implements the ability to shutdown your

506 but it is indepedent of the system firmware. And like a reboot
507 you can start any kernel with it, not just Linux.
508
509 The name comes from the similiarity to the exec system call.
510
511 It is an ongoing process to be certain the hardware in a machine
512 is properly shutdown, so do not be surprised if this code does not
513 initially work for you. It may help to enable device hotplugging
514 support. As of this writing the exact hardware interface is
515 strongly in flux, so no good recommendation can be made.

629 help
630 This kernel feature is useful for number crunching applications
631 that may need to compute untrusted bytecode during their
632 execution. By using pipes or other transports made available to
633 the process as file descriptors supporting the read/write
634 syscalls, it's possible to isolate those applications in
635 their own address space using seccomp. Once seccomp is
636 enabled via /proc/<pid>/seccomp, it cannot be disabled
637 and the task is only allowed to execute a few safe syscalls
638 defined by each seccomp mode.

640 If unsure, say Y. Only embedded should say N here.
