C Specification

To specify the values to use when waiting for and signaling semaphores whose current payload refers to a Direct3D 12 fence, add the VkD3D12FenceSubmitInfoKHR structure to the pNext chain of the VkSubmitInfo structure. The VkD3D12FenceSubmitInfoKHR structure is defined as:

typedef struct VkD3D12FenceSubmitInfoKHR {
    VkStructureType    sType;
    const void*        pNext;
    uint32_t           waitSemaphoreValuesCount;
    const uint64_t*    pWaitSemaphoreValues;
    uint32_t           signalSemaphoreValuesCount;
    const uint64_t*    pSignalSemaphoreValues;
} VkD3D12FenceSubmitInfoKHR;

Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to an extension-specific structure.

  • waitSemaphoreValuesCount is the number of semaphore wait values specified in pWaitSemaphoreValues.

  • pWaitSemaphoreValues is an array of length waitSemaphoreValuesCount containing values for the corresponding semaphores in VkSubmitInfo::pWaitSemaphores to wait for.

  • signalSemaphoreValuesCount is the number of semaphore signal values specified in pSignalSemaphoreValues.

  • pSignalSemaphoreValues is an array of length signalSemaphoreValuesCount containing values for the corresponding semaphores in VkSubmitInfo::pSignalSemaphores to set when signaled.

Description

If the semaphore in VkSubmitInfo::pWaitSemaphores or VkSubmitInfo::pSignalSemaphores corresponding to an entry in pWaitSemaphoreValues or pSignalSemaphoreValues respectively does not currently have a payload referring to a Direct3D 12 fence, the implementation must ignore the value in the pWaitSemaphoreValues or pSignalSemaphoreValues entry.

Valid Usage
  • waitSemaphoreValuesCount must be the same value as VkSubmitInfo::waitSemaphoreCount, where VkSubmitInfo is in the pNext chain of this VkD3D12FenceSubmitInfoKHR structure.

  • signalSemaphoreValuesCount must be the same value as VkSubmitInfo::signalSemaphoreCount, where VkSubmitInfo is in the pNext chain of this VkD3D12FenceSubmitInfoKHR structure.

Valid Usage (Implicit)
  • sType must be VK_STRUCTURE_TYPE_D3D12_FENCE_SUBMIT_INFO_KHR

  • If waitSemaphoreValuesCount is not 0, and pWaitSemaphoreValues is not NULL, pWaitSemaphoreValues must be a valid pointer to an array of waitSemaphoreValuesCount uint64_t values

  • If signalSemaphoreValuesCount is not 0, and pSignalSemaphoreValues is not NULL, pSignalSemaphoreValues must be a valid pointer to an array of signalSemaphoreValuesCount uint64_t values
