VkDriverId

Khronos driver IDs which may be returned in VkPhysicalDeviceDriverProperties::driverID are:

typedef enum VkDriverId {
    // Driver IDs are now represented as enums instead of the old
                 <driverids> tag, allowing them to be included in the
                 API headers.,

#define VkDriverIdKHR VkDriverId

Khronos driver IDs may be allocated by vendors at any time. There may be multiple driver IDs for the same vendor, representing different drivers (for e.g. different platforms, proprietary or open source, etc.). Only the latest canonical versions of this Specification, of the corresponding vk.xml API Registry, and of the corresponding vulkan_core.h header file must contain all reserved Khronos driver IDs.

Only driver IDs registered with Khronos are given symbolic names. There may be unregistered driver IDs returned.
