VkExternalMemoryProperties - Structure specifying external memory handle type capabilities

Description

compatibleHandleTypes must include at least handleType. Inclusion of a handle type in compatibleHandleTypes does not imply the values returned in ImageFormatProperties2 will be the same when PhysicalDeviceExternalImageFormatInfo::handleType is set to that type. The application is responsible for querying the capabilities of all handle types intended for concurrent use in a single image and intersecting them to obtain the compatible set of capabilities.

VkPhysicalDeviceExternalImageFormatInfo - Structure specifying external image creation parameters

Description

If handleType is 0, getPhysicalDeviceImageFormatProperties2 will behave as if PhysicalDeviceExternalImageFormatInfo was not present, and ExternalImageFormatProperties will be ignored.

If handleType is not compatible with the format, type, tiling, usage, and flags specified in PhysicalDeviceImageFormatInfo2, then getPhysicalDeviceImageFormatProperties2 returns ERROR_FORMAT_NOT_SUPPORTED.

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_PHYSICAL_DEVICE_EXTERNAL_IMAGE_FORMAT_INFO

• If handleType is not 0, handleType must be a valid ExternalMemoryHandleTypeFlagBits value

VkPhysicalDeviceIDProperties - Structure specifying IDs related to the physical device

Description

• deviceUUID is an array of UUID_SIZE uint8_t values representing a universally unique identifier for the device.

• driverUUID is an array of UUID_SIZE uint8_t values representing a universally unique identifier for the driver build in use by the device.
• deviceLUID is an array of LUID_SIZE uint8_t values representing a locally unique identifier for the device.
• deviceNodeMask is a uint32_t bitfield identifying the node within a linked device adapter corresponding to the device.
• deviceLUIDValid is a boolean value that will be TRUE if deviceLUID contains a valid LUID and deviceNodeMask contains a valid node mask, and FALSE if they do not.

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

Applications can compare the 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.

deviceUUID and/or 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:

• External memory handle types compatibility
• External semaphore handle types compatibility
• External fence handle types compatibility

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

Note

Although they have identical descriptions, PhysicalDeviceIDProperties::deviceUUID may differ from PhysicalDeviceProperties2::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 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 deviceUUID values are actually unique, so implementors should make their own best efforts to ensure this. In particular, hard-coded 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 deviceUUID which is unique to a high degree of certainty. Some possible inputs to such a computation are:

• Information reported by getPhysicalDeviceProperties
• PCI device ID (if defined)
• PCI bus ID, or similar system configuration information.
• Driver binary checksums.

Note

While PhysicalDeviceIDProperties::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.

VkStructureType - Vulkan structure types (sType)

Description

Each value corresponds to a particular structure with a sType member with a matching name. As a general rule, the name of each StructureType value is obtained by taking the name of the structure, stripping the leading Vk, prefixing each capital letter with _, converting the entire resulting string to upper case, and prefixing it with VK_STRUCTURE_TYPE_. For example, structures of type ImageCreateInfo correspond to a StructureType of STRUCTURE_TYPE_IMAGE_CREATE_INFO, and thus its sType member must equal that when it is passed to the API.

The values STRUCTURE_TYPE_LOADER_INSTANCE_CREATE_INFO and STRUCTURE_TYPE_LOADER_DEVICE_CREATE_INFO are reserved for internal use by the loader, and do not have corresponding Vulkan structures in this Specification.

VkExternalMemoryHandleTypeFlagBits - Bit specifying external memory handle types

Description

Some external memory handle types can only be shared within the same underlying physical device and/or the same driver version, as defined in the following table:

External memory handle types compatibility

Note

The above table does not restrict the drivers and devices with which EXTERNAL_MEMORY_HANDLE_TYPE_HOST_ALLOCATION_BIT_EXT and EXTERNAL_MEMORY_HANDLE_TYPE_HOST_MAPPED_FOREIGN_MEMORY_BIT_EXT may be shared, as these handle types inherently mean memory that does not come from the same device, as they import memory from the host or a foreign device, respectively.

Note

Even though the above table does not restrict the drivers and devices with which EXTERNAL_MEMORY_HANDLE_TYPE_DMA_BUF_BIT_EXT may be shared, query mechanisms exist in the Vulkan API that prevent the import of incompatible dma-bufs (such as getMemoryFdPropertiesKHR) and that prevent incompatible usage of dma-bufs (such as PhysicalDeviceExternalBufferInfo and PhysicalDeviceExternalImageFormatInfo).
