Links Exceptions as described in this article are generated by the CPU when an 'error' occurs. Some exceptions are not really errors in most page fault error code cases, such as page faults. Exceptions are a type of interrupt. Exceptions are classified as: Faults: These can be corrected and the program may continue as if nothing happened. Traps: Traps are reported immediately after the execution of the trapping

instruction. Aborts: Some severe unrecoverable error. Some exceptions will push a 32-bit "error code" on to the top of the stack, which provides additional information about the error. This value must be pulled from the stack before returning control back to the currently running program. (i.e. before calling IRET) Name Vector nr. Type Mnemonic Error code?

Many OS developers use this exception to test whether their exception handling code works. This exception may also occur when the result is too large to be represented in the destination. The saved instruction pointer points to the DIV or IDIV instruction which caused the exception. Bound Range Exceeded This exception can occur when the BOUND

(May 2011) (Learn how and when to remove this template message) A general protection fault (GPF) in the Intel x86 and AMD x86-64 http://wiki.osdev.org/Exceptions types of computer microprocessor architectures, and other unrelated architectures, is a fault (a type of interrupt) that can encompass several cases in which protection mechanisms within the processor architecture are violated by any of the programs that are running, either the kernel or a user program. The mechanism is first described in section 9.8.13 in the Intel 80386 programmer's reference manual https://en.wikipedia.org/wiki/General_protection_fault from 1986. A general protection fault is implemented as an interrupt (vector number 13 in decimal) in both the x86 and the AMD64 architectures. If the processor detects a protection violation, it stops executing the code and sends a GPF interrupt. In most cases the operating system removes the failing process from the execution queue, signals the user, and continues executing other processes. If, however, the operating system fails to catch the general protection fault, i.e. another protection violation occurs before the operating system returns from the previous GPF interrupt, the processor signals a double fault, stopping the operating system. If yet another failure (triple fault) occurs, the processor stops working and only responds to a reset.

as a fault, trap, or abort. This classification provides information needed by systems programmers for restarting the procedure in which the exception occurred: Faults The CS and EIP values saved when a fault is reported point to https://pdos.csail.mit.edu/6.828/2014/readings/i386/s09_08.htm the instruction causing the fault. Traps The CS and EIP values stored when the trap is reported point to the instruction dynamically after the instruction causing the trap. If a trap is detected during an http://searchwindowsserver.techtarget.com/definition/general-protection-fault-GPF instruction that alters program flow, the reported values of CS and EIP reflect the alteration of program flow. For example, if a trap is detected in a JMP instruction, the CS and EIP values pushed onto general protection the stack point to the target of the JMP, not to the instruction after the JMP. Aborts An abort is an exception that permits neither precise location of the instruction causing the exception nor restart of the program that caused the exception. Aborts are used to report severe errors, such as hardware errors and inconsistent or illegal values in system tables. 9.8.1 Interrupt 0 -- Divide Error The divide-error fault occurs general protection fault during a DIV or an IDIV instruction when the divisor is zero. 9.8.2 Interrupt 1 -- Debug Exceptions The processor triggers this interrupt for any of a number of conditions; whether the exception is a fault or a trap depends on the condition: Instruction address breakpoint fault. Data address breakpoint trap. General detect fault. Single-step trap. Task-switch breakpoint trap. The processor does not push an error code for this exception. An exception handler can examine the debug registers to determine which condition caused the exception . Refer to Chapter 12 for more detailed information about debugging and the debug registers. 9.8.3 Interrupt 3 -- Breakpoint The INT 3 instruction causes this trap. The INT 3 instruction is one byte long, which makes it easy to replace an opcode in an executable segment with the breakpoint opcode. The operating system or a debugging subsystem can use a data-segment alias for an executable segment to place an INT 3 anywhere it is convenient to arrest normal execution so that some sort of special processing can be performed. Debuggers typically use breakpoints as a way of displaying registers, variables, etc., at crucial points in a task. The saved CS:EIP value points to the byte following the breakpoint. If a debugger replaces a planted breakpo
