C Specification

The VkSemaphoreSciSyncCreateInfoNV structure is defined as:

// Provided by VK_NV_external_sci_sync2
typedef struct VkSemaphoreSciSyncCreateInfoNV {
    VkStructureType             sType;
    const void*                 pNext;
    VkSemaphoreSciSyncPoolNV    semaphorePool;
    const NvSciSyncFence*       pFence;
} VkSemaphoreSciSyncCreateInfoNV;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • semaphorePool is a VkSemaphoreSciSyncPoolNV handle.

  • pFence is a pointer to a NvSciSyncFence.

Description

When VkSemaphoreSciSyncCreateInfoNV is included in VkSemaphoreCreateInfo::pNext chain, the semaphore is created from the VkSemaphoreSciSyncPoolNV handle that represents a NvSciSyncObj with one or more primitives. The VkSemaphoreSciSyncCreateInfoNV::pFence parameter provides the information to select the corresponding primitive represented by this semaphore. When a NvSciSyncObj with signaler permissions is imported to VkSemaphoreSciSyncPoolNV, it only supports one primitive and VkSemaphoreSciSyncCreateInfoNV::pFence must be in the cleared state.

Valid Usage
Valid Usage (Implicit)

  • VUID-VkSemaphoreSciSyncCreateInfoNV-sType-sType
    sType must be VK_STRUCTURE_TYPE_SEMAPHORE_SCI_SYNC_CREATE_INFO_NV

  • VUID-VkSemaphoreSciSyncCreateInfoNV-semaphorePool-parameter
    semaphorePool must be a valid VkSemaphoreSciSyncPoolNV handle

  • VUID-VkSemaphoreSciSyncCreateInfoNV-pFence-parameter
    pFence must be a valid pointer to a valid NvSciSyncFence value
