C Specification

To submit sparse binding operations to a queue, call:

VkResult vkQueueBindSparse(
    VkQueue                                     queue,
    uint32_t                                    bindInfoCount,
    const VkBindSparseInfo*                     pBindInfo,
    VkFence                                     fence);

Parameters

  • queue is the queue that the sparse binding operations will be submitted to.

  • bindInfoCount is the number of elements in the pBindInfo array.

  • pBindInfo is an array of VkBindSparseInfo structures, each specifying a sparse binding submission batch.

  • fence is an optional handle to a fence to be signaled. If fence is not VK_NULL_HANDLE, it defines a fence signal operation.

Description

vkQueueBindSparse is a queue submission command, with each batch defined by an element of pBindInfo as an instance of the VkBindSparseInfo structure. Batches begin execution in the order they appear in pBindInfo, but may complete out of order.

Within a batch, a given range of a resource must not be bound more than once. Across batches, if a range is to be bound to one allocation and offset and then to another allocation and offset, then the application must guarantee (usually using semaphores) that the binding operations are executed in the correct order, as well as to order binding operations against the execution of command buffer submissions.

As no operation to vkQueueBindSparse causes any pipeline stage to access memory, synchronization primitives used in this command effectively only define execution dependencies.

Additional information about fence and semaphore operation is described in the synchronization chapter.

Valid Usage
  • If fence is not VK_NULL_HANDLE, fence must be unsignaled

  • If fence is not VK_NULL_HANDLE, fence must not be associated with any other queue command that has not yet completed execution on that queue

  • Each element of the pSignalSemaphores member of each element of pBindInfo must be unsignaled when the semaphore signal operation it defines is executed on the device

  • When a semaphore unsignal operation defined by any element of the pWaitSemaphores member of any element of pBindInfo executes on queue, no other queue must be waiting on the same semaphore.

  • All elements of the pWaitSemaphores member of all elements of pBindInfo must be semaphores that are signaled, or have semaphore signal operations previously submitted for execution.

Valid Usage (Implicit)
  • queue must be a valid VkQueue handle

  • If bindInfoCount is not 0, pBindInfo must be a valid pointer to an array of bindInfoCount valid VkBindSparseInfo structures

  • If fence is not VK_NULL_HANDLE, fence must be a valid VkFence handle

  • The queue must support sparse binding operations

  • Both of fence, and queue that are valid handles must have been created, allocated, or retrieved from the same VkDevice

Host Synchronization
  • Host access to queue must be externally synchronized

  • Host access to pBindInfo[].pWaitSemaphores[] must be externally synchronized

  • Host access to pBindInfo[].pSignalSemaphores[] must be externally synchronized

  • Host access to pBindInfo[].pBufferBinds[].buffer must be externally synchronized

  • Host access to pBindInfo[].pImageOpaqueBinds[].image must be externally synchronized

  • Host access to pBindInfo[].pImageBinds[].image must be externally synchronized

  • Host access to fence must be externally synchronized

Return Codes
On success, this command returns
  • VK_SUCCESS

On failure, this command returns
  • VK_ERROR_OUT_OF_HOST_MEMORY

  • VK_ERROR_OUT_OF_DEVICE_MEMORY

  • VK_ERROR_DEVICE_LOST
