C Specification

To query the PCI bus information of a physical device, add a VkPhysicalDevicePCIBusInfoPropertiesEXT structure to the pNext chain of the VkPhysicalDeviceProperties2 structure. The VkPhysicalDevicePCIBusInfoPropertiesEXT structure is defined as:

// Provided by VK_EXT_pci_bus_info
typedef struct VkPhysicalDevicePCIBusInfoPropertiesEXT {
    VkStructureType    sType;
    void*              pNext;
    uint32_t           pciDomain;
    uint32_t           pciBus;
    uint32_t           pciDevice;
    uint32_t           pciFunction;
} VkPhysicalDevicePCIBusInfoPropertiesEXT;


  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • pciDomain is the PCI bus domain.

  • pciBus is the PCI bus identifier.

  • pciDevice is the PCI device identifier.

  • pciFunction is the PCI device function identifier.
