interrupts
1. An asynchronous event that suspends normal
processing and temporarily diverts the flow of control
through an "interrupt handler" routine.
Interrupts may be caused by both hardware (I/O, timer,
machine check) and software (supervisor, system call or
trap instruction).
In general the computer responds to an interrupt by storing
the information about the current state of the running
program; storing information to identify the source of the
interrupt; and invoking a first-level interrupt handler.
This is usually a kernel level privileged process that can
discover the precise cause of the interrupt (e.g. if several
devices share one interrupt) and what must be done to keep
operating system tables (such as the process table) updated.
This first-level handler may then call another handler,
e.g. one associated with the particular device which generated
the interrupt.
2. Under MS-DOS, nearly synonymous with "system call"
because the OS and BIOS routines are both called using the
INT instruction (see interrupt list) and because programmers
so often have to bypass the operating system (going directly
to a BIOS interrupt) to get reasonable performance.

interrupt handler
(foldoc) | interrupt handler
A routine which is executed when an interrupt
occurs. Interrupt handlers typically deal with low-level
events in the hardware of a computer system such as a
character arriving at a serial port or a tick of a
real-time clock. Special care is required when writing an
interrupt handler to ensure that either the interrupt which
triggered the handler's execution is masked out (inhibitted)
until the handler exits, or the handler is re-entrant so
that multiple concurrent invocations will not interfere with
each other.
If interrupts are masked then the handler must execute as
quickly as possible so that important events are not missed.
This is often arranged by splitting the processing associated
with the event into "upper" and "lower" halves. The lower
part is the interrupt handler which masks out further
interrupts as required, checks that the appropriate event has
occurred (this may be necessary if several events share the
same interrupt), services the interrupt, e.g. by reading a
character from a UART and writing it to a queue, and
re-enabling interrupts.
The upper half executes as part of a user process. It waits
until the interrupt handler has run. Normally the {operating
system} is responsible for reactivating a process which is
waiting for some low-level event. It detects this by a shared
flag or by inspecting a shared queue or by some other
synchronisation mechanism. It is important that the upper and
lower halves do not interfere if an interrupt occurs during
the execution of upper half code. This is usually ensured by
disabling interrupts during critical sections of code such
as removing a character from a queue.

IRQ
(IRQ) The name of an input found on many processors which
causes the processor to suspend normal instruction execution
temporarily and to start executing an interrupt handler
routine. Such an input may be either "level sensitive" -
the interrupt condition will persist as long as the input is
active or "edge triggered" - an interrupt is signalled by a
low-to-high or high-to-low transition on the input. Some
processors have several interrupt request inputs allowing
different priority interrupts.

programmable interrupt controller
(foldoc) | Programmable Interrupt Controller
PIC A special-purpose {integrated
circuit} that functions as an overall manager in an
interrupt driven system. It accepts requests from the
peripheral equipment, determines which of the incoming
requests is of the highest priority, ascertains whether the
incoming request has a higher priority value than the level
currently being serviced, and issues an interrupt to the CPU
based on this determination.
PICs typically have eight interrupt lines, and two PICs are
often cascaded to provide 15 available interrupt lines.

System/390}'s SVC or the ARM's SWI) rather than by a
hardware event.
As with a hardware interrupt, this causes the processor to
store the current state, store identifying information about
the particular interrupt, and pass control to a first level
interrupt handler.
A trap is similar except that it is caused by an unexpected
software condition or error (e.g. divide by zero, undefined
instruction) rather than a deliberate instruction.

uninterruptible power supply
(foldoc) | Uninterruptible Power Supply
(UPS) A battery powered power supply unit that is
guaranteed to provide power to a computer in the event of
interruptions in the incoming mains electrical power.
Different rating UPSs will provide power for different lengths
of time.
Modern UPSs connect to the computer's serial port and
provide information such as battery time remaining, allowing
the computer to shut down gracefully before complete loss of
power.

interrupt
(jargon) | interrupt
1. [techspeak] n. On a computer, an event that interrupts normal processing
and temporarily diverts flow-of-control through an “interrupt handler”
routine. See also trap.
2. interj. A request for attention from a hacker. Often explicitly spoken.
“Interrupt — have you seen Joe recently?” See priority interrupt.
|
interrupts locked out
(jargon) | interrupts locked out
adj.
When someone is ignoring you. In a restaurant, after several fruitless
attempts to get the waitress's attention, a hacker might well observe “She
must have interrupts locked out”. The synonym interrupts disabled is also
common. Variations abound; “to have one's interrupt mask bit set” and “
interrupts masked out” are also heard. See also spl.
|
priority interrupt
(jargon) | priority interrupt
n.
[from the hardware term] Describes any stimulus compelling enough to yank
one right out of hack mode. Classically used to describe being dragged
away by an SO for immediate sex, but may also refer to more mundane
interruptions such as a fire alarm going off in the near vicinity. Also
called an NMI (non-maskable interrupt), especially in PC-land.

INTERRUPTIO
(bouvier) | INTERRUPTION. The effect of some act or circumstance which stops the course
of a prescription or act of limitation's.
2. Interruption of the use of a thing is natural or civil. Natural
interruption is an interruption in fact, which takes place whenever by some
act we cease truly to possess what we formerly possessed. Vide 4 Mason's
Rep. 404; 2 Y. & Jarv. 285. A right is not interrupted by: mere trespassers,
if the trespasser's were unknown; but if they were known, and the trespasses
frequent, and no legal proceeding instituted in consequence of them, they
then become legitimae interruptiones, of which Bracton speaks, and are
converted into adverse assertions of right, and if not promptly and
effectually litigated, they defeat the claim of rightful prescription; and
mere threats of action for the trespasses, without following them up, will
have no effect to preserve the right. Knapp, R. 70, 71; 3 Bar. & Ad. 863; 2
Saund. 175, n. e; 1 Camp. 260; 4 Camp. 16; 5 Taunt. 125 11 East, 376.
3. Civil interruption is that which takes place by some judicial act,
as the commencement of a suit to recover the thing in dispute, which gives
notice to the possessor that the thing which he possesses does not belong to
him. When the title has once been gained by prescription, it will not be
lost by interruption of it for ten or twenty years. 1 Inst. 113 b. A simple
acknowledgment of a debt by the debtor, is a sufficient interruption to
prevent the statute from running. Indeed, whenever an agreement, express or
implied, takes place between the creditor and the debtor, between the
possessor and the owner, which admits the indebtedness or the right to the
thing in dispute, it is considered a civil conventional interruption which
prevents the statute or the right of prescription from running. Vide 3 Burge
on the Confl. of Lalys, 63.
