524 can simulate a MIPS32 4Kc system. This patch adds support for the
525 system architecture that currently is being simulated by Qemu. It
526 will eventually be removed again when Qemu has the capability to
527 simulate actual MIPS hardware platforms. More information on Qemu

791 help
792 kexec is a system call that implements the ability to shutdown your
793 current kernel, and to start another kernel. It is like a reboot
794 but it is indepedent of the system firmware. And like a reboot
795 you can start any kernel with it, not just Linux.
796
797 The name comes from the similiarity to the exec system call.
798
799 It is an ongoing process to be certain the hardware in a machine
800 is properly shutdown, so do not be surprised if this code does not
801 initially work for you. It may help to enable device hotplugging
802 support. As of this writing the exact hardware interface is
803 strongly in flux, so no good recommendation can be made.

926 Some MIPS machines can be configured for either little or big endian
5e83d430 927 byte order. These modes require different kernels and a different
3cb2fccc 928 Linux distribution. In general there is one preferred byteorder for a

929 particular system but some systems are just as commonly used in the

1183 might be a safe bet. If the resulting kernel does not work,

1900 The Extended Industry Standard Architecture (EISA) bus was
1901 developed as an open alternative to the IBM MicroChannel bus.
1902
1903 The EISA bus provided some of the features of the IBM MicroChannel
1904 bus while maintaining backward compatibility with cards made for
1905 the older ISA bus. The EISA bus saw limited use between 1988 and
1906 1995 when it was made obsolete by the PCI bus.
1907
1908 Say Y here if you are building a kernel for an EISA-based machine.

1950 help
1951 A 64-bit kernel is usually built using the 64-bit ELF binary object
1952 format as it's one that allows arbitrary 64-bit constructs. For
1953 kernels that are loaded within the KSEG compatibility segments the
1954 32-bit ELF format can optionally be used resulting in a somewhat
1955 smaller binary, but this option is not explicitly supported by the
1956 toolchain and since binutils 2.14 it does not even work at all.
1957
1958 Say Y to use the 64-bit format or N to use the 32-bit one.

2014 This kernel feature is useful for number crunching applications
2015 that may need to compute untrusted bytecode during their
2016 execution. By using pipes or other transports made available to
2017 the process as file descriptors supporting the read/write
2018 syscalls, it's possible to isolate those applications in
2019 their own address space using seccomp. Once seccomp is
2020 enabled via /proc/<pid>/seccomp, it cannot be disabled
2021 and the task is only allowed to execute a few safe syscalls
2022 defined by each seccomp mode.

2033 ---help---
2034 APM is a BIOS specification for saving power using several different
2035 techniques. This is mostly useful for battery powered systems with
2036 APM compliant BIOSes. If you say Y here, the system time will be
2037 reset after a RESUME operation, the /proc/apm device will provide
2038 battery status information, and user-space programs will receive
2039 notification of APM "events" (e.g. battery status change).
2040
2041 In order to use APM, you will need supporting software. For location
2042 and more information, read <file:Documentation/pm.txt> and the
2043 Battery Powered Linux mini-HOWTO, available from
2044 <http://www.tldp.org/docs.html#howto>.
2045
2046 This driver does not spin down disk drives (see the hdparm(8)
2047 manpage ("man 8 hdparm") for that), and it doesn't turn off
2048 VESA-compliant "green" monitors.
2049
2050 Generally, if you don't have a battery in your machine, there isn't
2051 much point in using this driver and you should say N. If you get
2052 random kernel OOPSes or reboots that don't seem to be related to
2053 anything, try disabling/enabling this option (or disabling/enabling
2054 APM in your BIOS).
