C Specification

To import a fence payload from a NvSciSyncFence handle, call:

// Provided by VK_NV_external_sci_sync, VK_NV_external_sci_sync2
VkResult vkImportFenceSciSyncFenceNV(
    VkDevice                                    device,
    const VkImportFenceSciSyncInfoNV*           pImportFenceSciSyncInfo);

Parameters

  • device is the logical device that created the fence.

  • pImportFenceSciSyncInfo is a pointer to a VkImportFenceSciSyncInfoNV structure containing parameters of the import operation

Description

Importing a fence payload from NvSciSyncFence does not transfer ownership of the handle to the Vulkan implementation. Vulkan will make a copy of NvSciSyncFence when importing it. The application must release ownership using the NvSciSync API when the handle is no longer needed.

Valid Usage
Valid Usage (Implicit)

  • VUID-vkImportFenceSciSyncFenceNV-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkImportFenceSciSyncFenceNV-pImportFenceSciSyncInfo-parameter
    pImportFenceSciSyncInfo must be a valid pointer to a valid VkImportFenceSciSyncInfoNV structure

Return Codes
On success, this command returns

  • VK_SUCCESS

On failure, this command returns

  • VK_ERROR_INVALID_EXTERNAL_HANDLE

  • VK_ERROR_NOT_PERMITTED
