Description

Applications that wish to import Direct3D 11 memory objects into the Vulkan API may wish to use the native keyed mutex mechanism to synchronize access to the memory between Vulkan and Direct3D. This extension provides a way for an application to access the keyed mutex associated with an imported Vulkan memory object when submitting command buffers to a queue.

New Structures

• Extending SubmitInfo, SubmitInfo2:

  • Win32KeyedMutexAcquireReleaseInfoKHR

New Enum Constants

• KHR_WIN32_KEYED_MUTEX_EXTENSION_NAME

• KHR_WIN32_KEYED_MUTEX_SPEC_VERSION

• Extending StructureType:

  • STRUCTURE_TYPE_WIN32_KEYED_MUTEX_ACQUIRE_RELEASE_INFO_KHR

Version History

• Revision 1, 2016-10-21 (James Jones)

VkWin32KeyedMutexAcquireReleaseInfoKHR - Use the Windows keyed mutex mechanism to synchronize work

Valid Usage

• Each member of pAcquireSyncs and pReleaseSyncs must be a device memory object imported by setting ImportMemoryWin32HandleInfoKHR::handleType to EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_TEXTURE_BIT or EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_TEXTURE_KMT_BIT

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_WIN32_KEYED_MUTEX_ACQUIRE_RELEASE_INFO_KHR

• If acquireCount is not 0, pAcquireSyncs must be a valid pointer to an array of acquireCount valid DeviceMemory handles
• If acquireCount is not 0, pAcquireKeys must be a valid pointer to an array of acquireCount uint64_t values
• If acquireCount is not 0, pAcquireTimeouts must be a valid pointer to an array of acquireCount uint32_t values
• If releaseCount is not 0, pReleaseSyncs must be a valid pointer to an array of releaseCount valid DeviceMemory handles
• If releaseCount is not 0, pReleaseKeys must be a valid pointer to an array of releaseCount uint64_t values
• Both of the elements of pAcquireSyncs, and the elements of pReleaseSyncs that are valid handles of non-ignored parameters must have been created, allocated, or retrieved from the same Device

Constructors

Win32KeyedMutexAcquireReleaseInfoKHR

Fields

• acquireSyncs :: Vector DeviceMemory

  pAcquireSyncs is a pointer to an array of DeviceMemory objects which were imported from Direct3D 11 resources.

• acquireKeys :: Vector Word64

  pAcquireKeys is a pointer to an array of mutex key values to wait for prior to beginning the submitted work. Entries refer to the keyed mutex associated with the corresponding entries in pAcquireSyncs.

• acquireTimeouts :: Vector Word32

  pAcquireTimeouts is a pointer to an array of timeout values, in millisecond units, for each acquire specified in pAcquireKeys.

• releaseSyncs :: Vector DeviceMemory

  pReleaseSyncs is a pointer to an array of DeviceMemory objects which were imported from Direct3D 11 resources.

• releaseKeys :: Vector Word64

  pReleaseKeys is a pointer to an array of mutex key values to set when the submitted work has completed. Entries refer to the keyed mutex associated with the corresponding entries in pReleaseSyncs.
