This extension enables applications to -- create exportable Vulkan memory objects such that the underlying -- resources can be referenced outside the Vulkan instance that created -- them. -- -- == New Structures -- -- - Extending 'Vulkan.Core10.Image.ImageCreateInfo': -- -- - 'ExternalMemoryImageCreateInfoNV' -- -- - Extending 'Vulkan.Core10.Memory.MemoryAllocateInfo': -- -- - 'ExportMemoryAllocateInfoNV' -- -- == New Enum Constants -- -- - 'NV_EXTERNAL_MEMORY_EXTENSION_NAME' -- -- - 'NV_EXTERNAL_MEMORY_SPEC_VERSION' -- -- - Extending 'Vulkan.Core10.Enums.StructureType.StructureType': -- -- - 'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_EXPORT_MEMORY_ALLOCATE_INFO_NV' -- -- - 'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_EXTERNAL_MEMORY_IMAGE_CREATE_INFO_NV' -- -- == Issues -- -- 1) If memory objects are shared between processes and APIs, is this -- considered aliasing according to the rules outlined in the -- -- section? -- -- __RESOLVED__: Yes, but strict exceptions to the rules are added to allow -- some forms of aliasing in these cases. Further, other extensions may -- build upon these new aliasing rules to define specific support usage -- within Vulkan for imported native memory objects, or memory objects from -- other APIs. -- -- 2) Are new image layouts or metadata required to specify image layouts -- and layout transitions compatible with non-Vulkan APIs, or with other -- instances of the same Vulkan driver? -- -- __RESOLVED__: No. Separate instances of the same Vulkan driver running -- on the same GPU should have identical internal layout semantics, so -- applictions have the tools they need to ensure views of images are -- consistent between the two instances. Other APIs will fall into two -- categories: Those that are Vulkan compatible (a term to be defined by -- subsequent interopability extensions), or Vulkan incompatible. When -- sharing images with Vulkan incompatible APIs, the Vulkan image must be -- transitioned to the -- 'Vulkan.Core10.Enums.ImageLayout.IMAGE_LAYOUT_GENERAL' layout before -- handing it off to the external API. -- -- Note this does not attempt to address cross-device transitions, nor -- transitions to engines on the same device which are not visible within -- the Vulkan API. Both of these are beyond the scope of this extension. -- -- == Examples -- -- > // TODO: Write some sample code here. -- -- == Version History -- -- - Revision 1, 2016-08-19 (James Jones) -- -- - Initial draft -- -- == See Also -- -- 'ExportMemoryAllocateInfoNV', 'ExternalMemoryImageCreateInfoNV' -- -- == Document Notes -- -- For more information, see the -- -- -- This page is a generated document.
