C Specification

To query the properties of the driver corresponding to a physical device, add a VkPhysicalDeviceDriverProperties structure to the pNext chain of the VkPhysicalDeviceProperties2 structure. The VkPhysicalDeviceDriverProperties structure is defined as:

// Provided by VK_VERSION_1_2
typedef struct VkPhysicalDeviceDriverProperties {
    VkStructureType         sType;
    void*                   pNext;
    VkDriverId              driverID;
    char                    driverName[VK_MAX_DRIVER_NAME_SIZE];
    char                    driverInfo[VK_MAX_DRIVER_INFO_SIZE];
    VkConformanceVersion    conformanceVersion;
} VkPhysicalDeviceDriverProperties;

or the equivalent

// Provided by VK_KHR_driver_properties
typedef VkPhysicalDeviceDriverProperties VkPhysicalDeviceDriverPropertiesKHR;

Members

  • sType is the type of this structure.

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

Description

  • driverID is a unique identifier for the driver of the physical device.

  • driverName is an array of VK_MAX_DRIVER_NAME_SIZE char containing a null-terminated UTF-8 string which is the name of the driver.

  • driverInfo is an array of VK_MAX_DRIVER_INFO_SIZE char containing a null-terminated UTF-8 string with additional information about the driver.

  • conformanceVersion is the version of the Vulkan conformance test this driver is conformant against (see VkConformanceVersion).

driverID must be immutable for a given driver across instances, processes, driver versions, and system reboots.

Valid Usage (Implicit)
  • VUID-VkPhysicalDeviceDriverProperties-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_DRIVER_PROPERTIES
