Ralf Baechle5e83d432005-10-29 19:32:41 +0100866 byte order. These modes require different kernels and a different

1531 SMTC pseudo-interrupts between TCs are deferred and queued
1532 if the target TC is interrupt-inhibited (IXMT). In the first
1533 SMTC prototypes, these queued IPIs were serviced on return
1534 to user mode, or on entry into the kernel idle loop. The
1535 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1536 processing, which adds runtime overhead (hence the option to turn
1537 it off), but ensures that IPIs are handled promptly even under
1538 heavy I/O interrupt load.

1544 help
1545 To support multiple TC microthreads acting as "CPUs" within
1546 a VPE, VPE-wide interrupt mask bits must be specially manipulated
1547 during interrupt handling. To support legacy drivers and interrupt
1548 controller management code, SMTC has a "backstop" to track and
1549 if necessary restore the interrupt mask. This has some performance
1550 impact on interrupt service overhead. Disable it only if you know
1551 what you are doing.

1903 kexec is a system call that implements the ability to shutdown your
1904 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +02001905 but it is independent of the system firmware. And like a reboot
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09001906 you can start any kernel with it, not just Linux.
1907
Matt LaPlante01dd2fb2007-10-20 01:34:40 +02001908 The name comes from the similarity to the exec system call.
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09001909
1910 It is an ongoing process to be certain the hardware in a machine
1911 is properly shutdown, so do not be surprised if this code does not
1912 initially work for you. It may help to enable device hotplugging
1913 support. As of this writing the exact hardware interface is
1914 strongly in flux, so no good recommendation can be made.

1921 This kernel feature is useful for number crunching applications
1922 that may need to compute untrusted bytecode during their
1923 execution. By using pipes or other transports made available to
1924 the process as file descriptors supporting the read/write
1925 syscalls, it's possible to isolate those applications in
1926 their own address space using seccomp. Once seccomp is
1927 enabled via /proc/<pid>/seccomp, it cannot be disabled
1928 and the task is only allowed to execute a few safe syscalls
1929 defined by each seccomp mode.
1930
1931 If unsure, say Y. Only embedded should say N here.

1985 The Extended Industry Standard Architecture (EISA) bus was
1986 developed as an open alternative to the IBM MicroChannel bus.
1987
1988 The EISA bus provided some of the features of the IBM MicroChannel
1989 bus while maintaining backward compatibility with cards made for
1990 the older ISA bus. The EISA bus saw limited use between 1988 and
1991 1995 when it was made obsolete by the PCI bus.

1993 Say Y here if you are building a kernel for an EISA-based machine.
