C Specification

The VkSemaphoreSubmitInfo structure is defined as:

typedef struct VkSemaphoreSubmitInfo {
    VkStructureType          sType;
    const void*              pNext;
    VkSemaphore              semaphore;
    uint64_t                 value;
    VkPipelineStageFlags2    stageMask;
    uint32_t                 deviceIndex;
} VkSemaphoreSubmitInfo;

or the equivalent

// Provided by VK_KHR_synchronization2
typedef VkSemaphoreSubmitInfo VkSemaphoreSubmitInfoKHR;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • semaphore is a VkSemaphore affected by this operation.

  • value is ignored.

  • stageMask is a VkPipelineStageFlags2 mask of pipeline stages which limit the first synchronization scope of a semaphore signal operation, or second synchronization scope of a semaphore wait operation as described in the semaphore wait operation and semaphore signal operation sections of the synchronization chapter.

  • deviceIndex is the index of the device within a device group that executes the semaphore wait or signal operation.

Description

Whether this structure defines a semaphore wait or signal operation is defined by how it is used.

Valid Usage

  • VUID-VkSemaphoreSubmitInfo-stageMask-03929
    If the geometryShader feature is not enabled, stageMask must not contain VK_PIPELINE_STAGE_2_GEOMETRY_SHADER_BIT

  • VUID-VkSemaphoreSubmitInfo-stageMask-03930
    If the tessellationShader feature is not enabled, stageMask must not contain VK_PIPELINE_STAGE_2_TESSELLATION_CONTROL_SHADER_BIT or VK_PIPELINE_STAGE_2_TESSELLATION_EVALUATION_SHADER_BIT

  • VUID-VkSemaphoreSubmitInfo-stageMask-07317
    If the attachmentFragmentShadingRate feature is not enabled, stageMask must not contain VK_PIPELINE_STAGE_2_FRAGMENT_SHADING_RATE_ATTACHMENT_BIT_KHR

  • VUID-VkSemaphoreSubmitInfo-device-03888
    If the device that semaphore was created on is not a device group, deviceIndex must be 0

  • VUID-VkSemaphoreSubmitInfo-device-03889
    If the device that semaphore was created on is a device group, deviceIndex must be a valid device index

  • VUID-VkSemaphoreSubmitInfoKHR-semaphore-05094
    If semaphore has a payload of NvSciSyncObj, value must be calculated by application via NvSciSync APIs.

Valid Usage (Implicit)

  • VUID-VkSemaphoreSubmitInfo-sType-sType
    sType must be VK_STRUCTURE_TYPE_SEMAPHORE_SUBMIT_INFO

  • VUID-VkSemaphoreSubmitInfo-pNext-pNext
    pNext must be NULL

  • VUID-VkSemaphoreSubmitInfo-semaphore-parameter
    semaphore must be a valid VkSemaphore handle

  • VUID-VkSemaphoreSubmitInfo-stageMask-parameter
    stageMask must be a valid combination of VkPipelineStageFlagBits2 values
