A general protection fault (GPF) in the x86 instruction set architectures (ISAs) is a fault (a type of interrupt) initiated by ISA-defined protection mechanisms in response to an access violation caused by some running code, either in the kernel or a user program. The mechanism is first described in Intel manuals and datasheets for the Intel 80286 CPU, which was introduced in 1983; it is also described in section 9.8.13 in the Intel 80386 programmer's reference manual from 1986. A general protection fault is implemented as an interrupt (vector number 13 (0Dh)). Some operating systems may also classify some exceptions not related to access violations, such as illegal opcode exceptions, as general protection faults, even though they have nothing to do with memory protection. If a CPU detects

rdfs:comment	General Protection Fault (GPF) és un terme en anglès per a Fallada General de Protecció. (ca) Ogólny błąd ochrony (ang. general protection fault) – błąd pojawiający się w systemie architektury Intel x86, gdy bieżąco wykonywany program komputerowy w jakiś sposób narusza zasady korzystanie ze sprzętu, na którym jest wykonywany. Te zasady mają za zadanie chronić dane i inne programy przed oczywistymi i potencjalnie katastrofalnymi błędami wykonywania procesów. Błędy, które powodują wystąpienie ogólnego błędu ochrony, są zazwyczaj nieodwracalne i uważa się, że najbezpieczniejszą reakcją na nie jest przerwanie działania programu i usunięcie jego procesu (procesów) z systemu operacyjnego. (pl) General Protection Fault (GPF) é um termo em inglês para Falha Geral de Proteção, que indica um tipo de erro de exceção fatal que o Windows não consegue identificar, geralmente relacionado a violações de memória. (pt) 一般保护错误（英語：General protection fault，缩写：GPF）是在英特尔x86和AMDx86-64架构和其它架构中的一种错误（或者一种中断），指正在运行的程序（内核或用户态程序）违反处理器架构中的保护措施的情况。此机制最初在1986年英特尔80386处理器的程序员参考手册第9.8.13节中描述。一般保护错误通过中断（向量值13）实现。若处理器侦测到保护违例，会停止当前代码的执行，并发出GPF中断。大多数情形下，操作系统会简单地关闭触发GPF的进程，告知用户，并继续执行其它程序。但如果操作系统没能捕获这一错误（如在操作系统从GPF中断处理例程中返回前发生了另一次违例），处理器会发出（中断向量值8，一种常见的蓝屏情形）。如果再次发生了违例，则处理器会关闭（参见），其后只会响应复位（即按下机器的复位按钮）、启动（重新启动系统）或（除非其之前在处理此类中断时出错）。 (zh) A general protection fault (GPF) in the x86 instruction set architectures (ISAs) is a fault (a type of interrupt) initiated by ISA-defined protection mechanisms in response to an access violation caused by some running code, either in the kernel or a user program.

Mekanisme ini pertama kali dijelaskan di bab 9.8.13 dalam manual referensi programmer Intel 80386 pada tahun 1986. General protection fault diimplementasikan sebagai interrupt ( nomor 13 dalam desimal) dalam kedua arsitektur x86 dan AMD64. Aplikasi dapat dikatakan mengalami crash. (in)
