1908 smaller binary, but this option is not explicitly supported by the
1909 toolchain and since binutils 2.14 it does not even work at all.
1911 Say Y to use the 64-bit format or N to use the 32-bit one.
1916 bool "Include IRIX binary compatibility"
1917 depends on CPU_BIG_ENDIAN && 32BIT && BROKEN
1919 config MIPS32_COMPAT
1920 bool "Kernel support for Linux/MIPS 32-bit binary compatibility"
1923 Select this option if you want Linux/MIPS 32-bit binary
1924 compatibility. Since all software available for Linux/MIPS is
1925 currently 32-bit you should say Y here.
1929 depends on MIPS32_COMPAT
1933 bool "Kernel support for o32 binaries"
1934 depends on MIPS32_COMPAT
1936 Select this option if you want to run o32 binaries. These are pure
1937 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1938 existing binaries are in this format.
1943 bool "Kernel support for n32 binaries"
1944 depends on MIPS32_COMPAT
1946 Select this option if you want to run n32 binaries. These are
1947 64-bit binaries using 32-bit quantities for addressing and certain
1948 data that would normally be 64-bit. They are used in special
1955 default y if MIPS32_O32 || MIPS32_N32
1958 bool "Enable seccomp to safely compute untrusted bytecode"
1959 depends on PROC_FS && BROKEN
1962 This kernel feature is useful for number crunching applications
1963 that may need to compute untrusted bytecode during their
1964 execution. By using pipes or other transports made available to
1965 the process as file descriptors supporting the read/write
1966 syscalls, it's possible to isolate those applications in
1967 their own address space using seccomp. Once seccomp is
1968 enabled via /proc/<pid>/seccomp, it cannot be disabled
1969 and the task is only allowed to execute a few safe syscalls
1970 defined by each seccomp mode.
1972 If unsure, say Y. Only embedded should say N here.
1975 bool "Power Management support (EXPERIMENTAL)"
1976 depends on EXPERIMENTAL && SOC_AU1X00
1979 tristate "Advanced Power Management Emulation"
1982 APM is a BIOS specification for saving power using several different
1983 techniques. This is mostly useful for battery powered systems with
1984 APM compliant BIOSes. If you say Y here, the system time will be
1985 reset after a RESUME operation, the /proc/apm device will provide
1986 battery status information, and user-space programs will receive
1987 notification of APM "events" (e.g. battery status change).
1989 In order to use APM, you will need supporting software. For location
1990 and more information, read <file:Documentation/pm.txt> and the
1991 Battery Powered Linux mini-HOWTO, available from
1992 <http://www.tldp.org/docs.html#howto>.
1994 This driver does not spin down disk drives (see the hdparm(8)
1995 manpage ("man 8 hdparm") for that), and it doesn't turn off
1996 VESA-compliant "green" monitors.
1998 Generally, if you don't have a battery in your machine, there isn't
1999 much point in using this driver and you should say N. If you get
2000 random kernel OOPSes or reboots that don't seem to be related to
2001 anything, try disabling/enabling this option (or disabling/enabling
