/**
 * Structure specifying IDs related to the physical device.
 * 
 * 
Description
* *

If the {@link VkPhysicalDeviceIDProperties} structure is included in the {@code pNext} chain of the {@link VkPhysicalDeviceProperties2} structure passed to {@link VK11#vkGetPhysicalDeviceProperties2 GetPhysicalDeviceProperties2}, it is filled in with each corresponding implementation-dependent property.

* *

{@code deviceUUID} must be immutable for a given device across instances, processes, driver APIs, driver versions, and system reboots.

* *

Applications can compare the {@code driverUUID} value across instance and process boundaries, and can make similar queries in external APIs to determine whether they are capable of sharing memory objects and resources using them with the device.

* *

{@code deviceUUID} and/or {@code driverUUID} must be used to determine whether a particular external object can be shared between driver components, where such a restriction exists as defined in the compatibility table for the particular object type:

* * * *

If {@code deviceLUIDValid} is {@link VK10#VK_FALSE FALSE}, the values of {@code deviceLUID} and {@code deviceNodeMask} are undefined. If {@code deviceLUIDValid} is {@link VK10#VK_TRUE TRUE} and Vulkan is running on the Windows operating system, the contents of {@code deviceLUID} can be cast to an {@code LUID} object and must be equal to the locally unique identifier of a {@code IDXGIAdapter1} object that corresponds to {@code physicalDevice}. If {@code deviceLUIDValid} is {@link VK10#VK_TRUE TRUE}, {@code deviceNodeMask} must contain exactly one bit. If Vulkan is running on an operating system that supports the Direct3D 12 API and {@code physicalDevice} corresponds to an individual device in a linked device adapter, {@code deviceNodeMask} identifies the Direct3D 12 node corresponding to {@code physicalDevice}. Otherwise, {@code deviceNodeMask} must be 1.

* *
Note
* *

Although they have identical descriptions, {@link VkPhysicalDeviceIDProperties}{@code ::deviceUUID} may differ from {@link VkPhysicalDeviceProperties2}{@code ::pipelineCacheUUID}. The former is intended to identify and correlate devices across API and driver boundaries, while the latter is used to identify a compatible device and driver combination to use when serializing and de-serializing pipeline state.

* *

Implementations should return {@code deviceUUID} values which are likely to be unique even in the presence of multiple Vulkan implementations (such as a GPU driver and a software renderer; two drivers for different GPUs; or the same Vulkan driver running on two logically different devices).

* *

Khronos' conformance testing can not guarantee that {@code deviceUUID} values are actually unique, so implementors should make their own best efforts to ensure this. In particular, hard-coded {@code deviceUUID} values, especially all-0 bits, should never be used.

* *

A combination of values unique to the vendor, the driver, and the hardware environment can be used to provide a {@code deviceUUID} which is unique to a high degree of certainty. Some possible inputs to such a computation are:

* *
    *
  • Information reported by {@link VK10#vkGetPhysicalDeviceProperties GetPhysicalDeviceProperties}
  • *
  • PCI device ID (if defined)
  • *
  • PCI bus ID, or similar system configuration information.
  • *
  • Driver binary checksums.
  • *
*
* *
Note
* *

While {@link VkPhysicalDeviceIDProperties}{@code ::deviceUUID} is specified to remain consistent across driver versions and system reboots, it is not intended to be usable as a serializable persistent identifier for a device. It may change when a device is physically added to, removed from, or moved to a different connector in a system while that system is powered down. Further, there is no reasonable way to verify with conformance testing that a given device retains the same UUID in a given system across all driver versions supported in that system. While implementations should make every effort to report consistent device UUIDs across driver versions, applications should avoid relying on the persistence of this value for uses other than identifying compatible devices for external object sharing purposes.

*
* *
