Field Documentation

IntcInterrupt

CM_ARCH_COMMON_GENERIC_INTERRUPT CmArchCommonPciInterruptMapInfo::IntcInterrupt

Interrupt controller interrupt.

Cf Devicetree Specification - Release v0.3 s2.4.3 "Interrupt Nexus Properties": "parent interrupt specifier"

Definition at line 245 of file ArchCommonNameSpaceObjects.h.

PciBus

UINT8 CmArchCommonPciInterruptMapInfo::PciBus

Pci Bus. Value on 8 bits (max 255).

Definition at line 223 of file ArchCommonNameSpaceObjects.h.

PciDevice

UINT8 CmArchCommonPciInterruptMapInfo::PciDevice

Pci Device. Value on 5 bits (max 31).

Definition at line 227 of file ArchCommonNameSpaceObjects.h.

PciInterrupt

UINT8 CmArchCommonPciInterruptMapInfo::PciInterrupt

PCI interrupt

ACPI bindings are used: Cf. ACPI 6.4, s6.2.13 _PRT (PCI Routing Table): "0-INTA, 1-INTB, 2-INTC, 3-INTD"

Device-tree bindings are shifted by 1: "INTA=1, INTB=2, INTC=3, INTD=4"
