HV_INTERRUPT_TYPE

Overview

Enumeration of interrupt delivery modes per architecture.

Syntax

typedef enum _HV_INTERRUPT_TYPE
{
#if defined(_ARM64_)
    HvArm64InterruptTypeFixed             = 0x0000,
#else
    HvX64InterruptTypeFixed             = 0x0000,
    HvX64InterruptTypeLowestPriority    = 0x0001,
    HvX64InterruptTypeSmi               = 0x0002,
    HvX64InterruptTypeRemoteRead        = 0x0003,
    HvX64InterruptTypeNmi               = 0x0004,
    HvX64InterruptTypeInit              = 0x0005,
    HvX64InterruptTypeSipi              = 0x0006,
    HvX64InterruptTypeExtInt            = 0x0007,
    HvX64InterruptTypeLocalInt0         = 0x0008,
    HvX64InterruptTypeLocalInt1         = 0x0009,
#endif
} HV_INTERRUPT_TYPE;

The interrupt types have different meanings depending on the processor architecture:

ARM64 Values

  • HvArm64InterruptTypeFixed – Standard fixed delivery.

x64 Values

  • HvX64InterruptTypeFixed – Fixed vector.
  • HvX64InterruptTypeLowestPriority – Dynamic routing to lowest priority.
  • HvX64InterruptTypeSmi – System Management Interrupt (restricted).
  • HvX64InterruptTypeRemoteRead – Remote read IPI.
  • HvX64InterruptTypeNmi – Non-maskable interrupt.
  • HvX64InterruptTypeInit – INIT IPI.
  • HvX64InterruptTypeSipi – SIPI (startup IPI).
  • HvX64InterruptTypeExtInt – External interrupt signal.
  • HvX64InterruptTypeLocalInt0 / LocalInt1 – Local APIC LINT pins.
