C Specification

The VkSciSyncAttributesInfoNV structure is defined as:

// Provided by VK_NV_external_sci_sync, VK_NV_external_sci_sync2
typedef struct VkSciSyncAttributesInfoNV {
    VkStructureType             sType;
    const void*                 pNext;
    VkSciSyncClientTypeNV       clientType;
    VkSciSyncPrimitiveTypeNV    primitiveType;
} VkSciSyncAttributesInfoNV;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • clientType is the permission type of client.

  • primitiveType is the synchronization primitive type.

Description

NvSciSync disallows multi-signalers, therefore clients must specify their permission types as one of signaler, waiter or signaler_waiter. In addition, NvSciSync requires clients to specify which primitive type is to be used in synchronization, hence clients also need to provide the primitive type (VkFence or VkSemaphore) that will be used.

Valid Usage (Implicit)

  • VUID-VkSciSyncAttributesInfoNV-sType-sType
    sType must be VK_STRUCTURE_TYPE_SCI_SYNC_ATTRIBUTES_INFO_NV

  • VUID-VkSciSyncAttributesInfoNV-pNext-pNext
    pNext must be NULL

  • VUID-VkSciSyncAttributesInfoNV-clientType-parameter
    clientType must be a valid VkSciSyncClientTypeNV value

  • VUID-VkSciSyncAttributesInfoNV-primitiveType-parameter
    primitiveType must be a valid VkSciSyncPrimitiveTypeNV value
