  2. HLT (x86 instruction) - Wikipedia

    en.wikipedia.org/wiki/HLT_(x86_instruction)

    In the x86 computer architecture, HLT (halt) is an assembly language instruction which halts the central processing unit (CPU) until the next external interrupt is fired. [1] Interrupts are signals sent by hardware devices to the CPU alerting it that an event occurred to which it should react.

    If the user has enabled it, the system will also write an entry to the system event log. The log entry contains information about the bug check (including the bug check code and its parameters) as well as a link that will report the bug and provide the user with prescriptive suggestions if the cause of the check is definitive and well-known.

  5. Kernel (operating system) - Wikipedia

    en.wikipedia.org/wiki/Kernel_(operating_system)

    An alternative approach is to use language-based protection. In a language-based protection system, the kernel will only allow code to execute that has been produced by a trusted language compiler. The language may then be designed such that it is impossible for the programmer to instruct it to do something that will violate a security requirement.

  6. General protection fault - Wikipedia

    en.wikipedia.org/wiki/General_protection_fault

    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.

  7. Halt and Catch Fire (computing) - Wikipedia

    en.wikipedia.org/wiki/Halt_and_Catch_Fire...

    The Motorola 6800 microprocessor was the first for which an undocumented assembly mnemonic HCF became widely known. The operation codes (opcodes—the portions of the machine language instructions that specify an operation to be performed) hexadecimal 9D and DD were reported and given the unofficial mnemonic HCF in a December 1977 article by Gerry Wheeler in BYTE magazine on undocumented ...

  8. evdev - Wikipedia

    en.wikipedia.org/wiki/Evdev

    evdev (short for 'event device') is a generic input event interface in the Linux kernel and FreeBSD. [1] It generalizes raw input events from device drivers and makes them available through character devices in the /dev/input/ directory. The user-space library for the kernel component evdev is called libevdev.

  9. Page fault - Wikipedia

    en.wikipedia.org/wiki/Page_fault

    The MMU detects the page fault, but the operating system's kernel handles the exception by making the required page accessible in the physical memory or denying an illegal memory access. Valid page faults are common and necessary to increase the amount of memory available to programs in any operating system that uses virtual memory , such as ...
