C Specification

The VkSemaphoreSignalInfo structure is defined as:

// Provided by VK_VERSION_1_2
typedef struct VkSemaphoreSignalInfo {
    VkStructureType    sType;
    const void*        pNext;
    VkSemaphore        semaphore;
    uint64_t           value;
} VkSemaphoreSignalInfo;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • semaphore is the handle of the semaphore to signal.

  • value is the value to signal.

Description

Valid Usage
  • VUID-VkSemaphoreSignalInfo-semaphore-03257
    semaphore must have been created with a VkSemaphoreType of VK_SEMAPHORE_TYPE_TIMELINE

  • VUID-VkSemaphoreSignalInfo-value-03258
    value must have a value greater than the current value of the semaphore

  • VUID-VkSemaphoreSignalInfo-value-03259
    value must be less than the value of any pending semaphore signal operations

  • VUID-VkSemaphoreSignalInfo-value-03260
    value must have a value which does not differ from the current value of the semaphore or the value of any outstanding semaphore wait or signal operation on semaphore by more than maxTimelineSemaphoreValueDifference

  • VUID-VkSemaphoreSignalInfo-semaphores-05125
    If semaphores has NvSciSyncObj as payload, application must calculate the corresponding timeline semaphore value in value by calling NvSciSync APIs.

Valid Usage (Implicit)
  • VUID-VkSemaphoreSignalInfo-sType-sType
    sType must be VK_STRUCTURE_TYPE_SEMAPHORE_SIGNAL_INFO

  • VUID-VkSemaphoreSignalInfo-pNext-pNext
    pNext must be NULL

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