The Interrupt flag (IF) is a flag bit in the CPU's FLAGS register, which determines whether or not the (CPU) will respond immediately to maskable hardware interrupts. [1] If the flag is set to 1 maskable interrupts are enabled. If reset (set to 0) such interrupts will be disabled until
The FLAGS register is the status register that contains the current state of an x86 CPU.The size and meanings of the flag bits are architecture dependent. It usually reflects the result of arithmetic operations as well as information about restrictions placed on the CPU operation at the current time.
If a signal comes in at a higher priority, then the current interrupt will be put into a pending state; the CPU sets the interrupt mask to the priority and places any interrupts with a lower priority into a pending state until the CPU finishes handling the new, higher priority interrupt. [1] Windows maps not only hardware interrupt levels to ...
XCR0, or Extended Control Register 0, is a control register which is used to toggle the storing or loading of registers related to specific CPU features using the XSAVE/XRSTOR instructions. It is also used with some features to enable or disable the processor's ability to execute their corresponding instructions.
INT 10h, INT 10H or INT 16 is shorthand for BIOS interrupt call 10 hex, the 17th interrupt vector in an x86-based computer system.The BIOS typically sets up a real mode interrupt handler at this vector that provides video services.

Maximum interrupt latency is largely determined by the methods an OS uses for interrupt handling. For example, most processors allow programs to disable interrupts, putting off the execution of interrupt handlers, in order to protect critical sections of code. During the execution of such a critical section, all interrupt handlers that cannot ...
