1538 SMTC pseudo-interrupts between TCs are deferred and queued
1539 if the target TC is interrupt-inhibited (IXMT). In the first
1540 SMTC prototypes, these queued IPIs were serviced on return
1541 to user mode, or on entry into the kernel idle loop. The
1542 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1543 processing, which adds runtime overhead (hence the option to turn
1544 it off), but ensures that IPIs are handled promptly even under
1545 heavy I/O interrupt load.

1551 help
1552 To support multiple TC microthreads acting as "CPUs" within
1553 a VPE, VPE-wide interrupt mask bits must be specially manipulated
1554 during interrupt handling. To support legacy drivers and interrupt
1555 controller management code, SMTC has a "backstop" to track and
1556 if necessary restore the interrupt mask. This has some performance
1557 impact on interrupt service overhead. Disable it only if you know

Linus Torvalds1da177e2005-04-16 15:20:36 -07001910 help
1911 MIPS R10000 does support a 44 bit / 16TB address space as opposed to
1912 previous 64-bit processors which only supported 40 bit / 1TB. If you
1913 need processes of more than 1TB virtual address space, say Y here.
1914 This will result in additional memory usage, so it is not
1915 recommended for normal users.

1919 depends on EXPERIMENTAL
1920 help
1921 kexec is a system call that implements the ability to shutdown your
1922 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +02001923 but it is independent of the system firmware. And like a reboot
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09001924 you can start any kernel with it, not just Linux.
1925
Matt LaPlante01dd2fb2007-10-20 01:34:40 +02001926 The name comes from the similarity to the exec system call.
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09001927
1928 It is an ongoing process to be certain the hardware in a machine
1929 is properly shutdown, so do not be surprised if this code does not
1930 initially work for you. It may help to enable device hotplugging
1931 support. As of this writing the exact hardware interface is
1932 strongly in flux, so no good recommendation can be made.

1938 help
1939 This kernel feature is useful for number crunching applications
1940 that may need to compute untrusted bytecode during their
1941 execution. By using pipes or other transports made available to
1942 the process as file descriptors supporting the read/write
1943 syscalls, it's possible to isolate those applications in
1944 their own address space using seccomp. Once seccomp is
1945 enabled via /proc/<pid>/seccomp, it cannot be disabled
1946 and the task is only allowed to execute a few safe syscalls
1947 defined by each seccomp mode.
1948
1949 If unsure, say Y. Only embedded should say N here.

2003 The Extended Industry Standard Architecture (EISA) bus was
2004 developed as an open alternative to the IBM MicroChannel bus.
2005
2006 The EISA bus provided some of the features of the IBM MicroChannel
2007 bus while maintaining backward compatibility with cards made for
2008 the older ISA bus. The EISA bus saw limited use between 1988 and
2009 1995 when it was made obsolete by the PCI bus.
