C Specification

If the pNext chain of VkDeviceObjectReservationCreateInfo includes a VkDeviceSemaphoreSciSyncPoolReservationCreateInfoNV structure, then the structure indicates the maximum number of VkSemaphoreSciSyncPoolNV objects that can exist at the same time.

The VkDeviceSemaphoreSciSyncPoolReservationCreateInfoNV structure is defined as:

// Provided by VKSC_VERSION_1_0 with VK_NV_external_sci_sync2
typedef struct VkDeviceSemaphoreSciSyncPoolReservationCreateInfoNV {
    VkStructureType    sType;
    const void*        pNext;
    uint32_t           semaphoreSciSyncPoolRequestCount;
} VkDeviceSemaphoreSciSyncPoolReservationCreateInfoNV;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • semaphoreSciSyncPoolRequestCount is the requested maximum number of VkSemaphoreSciSyncPoolNV objects that can exist at the same time.

Description

If the VkDeviceObjectReservationCreateInfo::pNext chain does not include this structure, then semaphoreSciSyncPoolRequestCount defaults to 0.

Multiple VkDeviceSemaphoreSciSyncPoolReservationCreateInfoNV structures can be chained together. The sum of the semaphoreSciSyncPoolRequestCount values from all instances of VkDeviceSemaphoreSciSyncPoolReservationCreateInfoNV will be reserved.

Valid Usage (Implicit)

  • VUID-VkDeviceSemaphoreSciSyncPoolReservationCreateInfoNV-sType-sType
    sType must be VK_STRUCTURE_TYPE_DEVICE_SEMAPHORE_SCI_SYNC_POOL_RESERVATION_CREATE_INFO_NV
