822 This is useful for kernel debugging when your machine crashes very
Robert P. J. Day490dcc42007-05-20 12:11:07 -0400823 early before the console code is initialized. For normal operation,
824 it is not recommended because it looks ugly on some machines and

1544 SMTC pseudo-interrupts between TCs are deferred and queued
1545 if the target TC is interrupt-inhibited (IXMT). In the first
1546 SMTC prototypes, these queued IPIs were serviced on return
1547 to user mode, or on entry into the kernel idle loop. The
1548 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1549 processing, which adds runtime overhead (hence the option to turn
1550 it off), but ensures that IPIs are handled promptly even under
1551 heavy I/O interrupt load.

1558 To support multiple TC microthreads acting as "CPUs" within
1559 a VPE, VPE-wide interrupt mask bits must be specially manipulated
1560 during interrupt handling. To support legacy drivers and interrupt
1561 controller management code, SMTC has a "backstop" to track and

1917 MIPS R10000 does support a 44 bit / 16TB address space as opposed to
1918 previous 64-bit processors which only supported 40 bit / 1TB. If you
1919 need processes of more than 1TB virtual address space, say Y here.

1926 help
1927 kexec is a system call that implements the ability to shutdown your
1928 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +02001929 but it is independent of the system firmware. And like a reboot
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09001930 you can start any kernel with it, not just Linux.
1931
Matt LaPlante01dd2fb2007-10-20 01:34:40 +02001932 The name comes from the similarity to the exec system call.
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09001933
1934 It is an ongoing process to be certain the hardware in a machine
1935 is properly shutdown, so do not be surprised if this code does not
1936 initially work for you. It may help to enable device hotplugging
1937 support. As of this writing the exact hardware interface is
1938 strongly in flux, so no good recommendation can be made.

1945 This kernel feature is useful for number crunching applications
1946 that may need to compute untrusted bytecode during their
1947 execution. By using pipes or other transports made available to
1948 the process as file descriptors supporting the read/write
1949 syscalls, it's possible to isolate those applications in
1950 their own address space using seccomp. Once seccomp is
1951 enabled via /proc/<pid>/seccomp, it cannot be disabled
1952 and the task is only allowed to execute a few safe syscalls
1953 defined by each seccomp mode.
