Interactions and External Dependencies
  • Promoted to Vulkan 1.1 Core

Contributors

Description

An application using external memory may wish to synchronize access to that memory using fences. This extension enables an application to create fences from which non-Vulkan handles that reference the underlying synchronization primitive can be exported.

Promotion to Vulkan 1.1

All functionality in this extension is included in core Vulkan 1.1, with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.

New Structures

New Bitmasks

New Enum Constants

  • VK_KHR_EXTERNAL_FENCE_EXTENSION_NAME

  • VK_KHR_EXTERNAL_FENCE_SPEC_VERSION

  • Extending VkFenceImportFlagBits:

    • VK_FENCE_IMPORT_TEMPORARY_BIT_KHR

  • Extending VkStructureType:

    • VK_STRUCTURE_TYPE_EXPORT_FENCE_CREATE_INFO_KHR

Issues

This extension borrows concepts, semantics, and language from VK_KHR_external_semaphore. That extension’s issues apply equally to this extension.
