# vkQueueSubmit(3) Manual Page

## Name

vkQueueSubmit - Submits a sequence of semaphores or command buffers to a queue

Loading… please wait.

## C Specification

To submit command buffers to a queue, call:

    // Provided by VK_VERSION_1_0
    VkResult vkQueueSubmit(
        VkQueue                                     queue,
        uint32_t                                    submitCount,
        const VkSubmitInfo*                         pSubmits,
        VkFence                                     fence);

## Parameters

- `queue` is the queue that the command buffers will be submitted to.

- `submitCount` is the number of elements in the `pSubmits` array.

- `pSubmits` is a pointer to an array of VkSubmitInfo structures, each specifying a command buffer submission batch. Command buffers and semaphores specified in this array may be accessed at any point until the queue operations they define complete execution on the device.

- `fence` is an optional handle to a fence to be signaled once all submitted command buffers have completed execution. If `fence` is not VK_NULL_HANDLE, it defines a fence signal operation. If it is not VK_NULL_HANDLE, `fence` may be accessed at any point until this command completes on the device.

## Description

`vkQueueSubmit` is a queue submission command, with each batch defined by an element of `pSubmits`. Batches begin execution in the order they appear in `pSubmits`, but may complete out of order.

Fence and semaphore operations submitted with vkQueueSubmit have additional ordering constraints compared to other submission commands, with dependencies involving previous and subsequent queue operations. Information about these additional constraints can be found in the semaphore and fence sections of the synchronization chapter.

Details on the interaction of `pWaitDstStageMask` with synchronization are described in the semaphore wait operation section of the synchronization chapter.

The order that batches appear in `pSubmits` is used to determine submission order, and thus all the implicit ordering guarantees that respect it. Other than these implicit ordering guarantees and any explicit synchronization primitives, these batches may overlap or otherwise execute out of order.

If any command buffer submitted to this queue is in the executable state, it is moved to the pending state. Once execution of all submissions of a command buffer complete, it moves from the pending state, back to the executable state. If a command buffer was recorded with the `VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT` flag, it instead moves to the invalid state.

If `vkQueueSubmit` fails, it may return `VK_ERROR_OUT_OF_HOST_MEMORY` or `VK_ERROR_OUT_OF_DEVICE_MEMORY`. If it does, the implementation must ensure that the state and contents of any resources or synchronization primitives referenced by the submitted command buffers and any semaphores referenced by `pSubmits` is unaffected by the call or its failure. If `vkQueueSubmit` fails in such a way that the implementation is unable to make that guarantee, the implementation must return `VK_ERROR_DEVICE_LOST`. See Lost Device.

Valid Usage

  Any calls to vkCmdSetEvent, vkCmdResetEvent or vkCmdWaitEvents that have been recorded into any of the command buffer elements of the `pCommandBuffers` member of any element of `pSubmits`, must not reference any VkEvent that is referenced by any of those commands in a command buffer that has been submitted to another queue and is still in the pending state

- VUID-vkQueueSubmit-pWaitDstStageMask-00066
  Any stage flag included in any element of the `pWaitDstStageMask` member of any element of `pSubmits` must be a pipeline stage supported by one of the capabilities of `queue`, as specified in the table of supported pipeline stages

- VUID-vkQueueSubmit-pSignalSemaphores-00067

- VUID-vkQueueSubmit-pWaitSemaphores-00068
  When a semaphore wait operation referring to a binary semaphore defined by any element of the `pWaitSemaphores` member of any element of `pSubmits` executes on `queue`, there must be no other queues waiting on the same semaphore

- VUID-vkQueueSubmit-pWaitSemaphores-03238
  All elements of the `pWaitSemaphores` member of all elements of `pSubmits` created with a VkSemaphoreType of `VK_SEMAPHORE_TYPE_BINARY` must reference a semaphore signal operation that has been submitted for execution and any semaphore signal operations on which it depends must have also been submitted for execution

- VUID-vkQueueSubmit-pCommandBuffers-00070
  Each element of the `pCommandBuffers` member of each element of `pSubmits` must be in the pending or executable state

- VUID-vkQueueSubmit-pCommandBuffers-00071
  If any element of the `pCommandBuffers` member of any element of `pSubmits` was not recorded with the `VK_COMMAND_BUFFER_USAGE_SIMULTANEOUS_USE_BIT`, it must not be in the pending state

- VUID-vkQueueSubmit-pCommandBuffers-00072
  Any secondary command buffers recorded into any element of the `pCommandBuffers` member of any element of `pSubmits` must be in the pending or executable state

- VUID-vkQueueSubmit-pCommandBuffers-00073
  If any secondary command buffers recorded into any element of the `pCommandBuffers` member of any element of `pSubmits` was not recorded with the `VK_COMMAND_BUFFER_USAGE_SIMULTANEOUS_USE_BIT`, it must not be in the pending state

- VUID-vkQueueSubmit-pCommandBuffers-00074
  Each element of the `pCommandBuffers` member of each element of `pSubmits` must have been allocated from a `VkCommandPool` that was created for the same queue family `queue` belongs to

- VUID-vkQueueSubmit-pSubmits-02207
  If any element of `pSubmits->pCommandBuffers` includes a Queue Family Ownership Transfer Acquire Operation, there must exist a previously submitted Queue Family Ownership Transfer Release Operation on a queue in the queue family identified by the acquire operation, with parameters matching the acquire operation as defined in the definition of such acquire operations, and which happens-before the acquire operation

- VUID-vkQueueSubmit-pCommandBuffers-03220
  If a command recorded into any element of `pCommandBuffers` was a vkCmdBeginQuery whose `queryPool` was created with a `queryType` of `VK_QUERY_TYPE_PERFORMANCE_QUERY_KHR`, the profiling lock must have been held continuously on the `VkDevice` that `queue` was retrieved from, throughout recording of those command buffers

- VUID-vkQueueSubmit-pSubmits-02808
  Any resource created with `VK_SHARING_MODE_EXCLUSIVE` that is read by an operation specified by `pSubmits` must not be owned by any queue family other than the one which `queue` belongs to, at the time it is executed

- VUID-vkQueueSubmit-pSubmits-04626
  Any resource created with `VK_SHARING_MODE_CONCURRENT` that is accessed by an operation specified by `pSubmits` must have included the queue family of `queue` at resource creation time

- VUID-vkQueueSubmit-queue-06448
  If `queue` was not created with `VK_DEVICE_QUEUE_CREATE_PROTECTED_BIT`, there must be no element of `pSubmits` that includes a VkProtectedSubmitInfo structure in its `pNext` chain with `protectedSubmit` equal to `VK_TRUE`

Valid Usage (Implicit)

- VUID-vkQueueSubmit-queue-parameter
  `queue` must be a valid VkQueue handle

- VUID-vkQueueSubmit-pSubmits-parameter
  If `submitCount` is not `0`, `pSubmits` must be a valid pointer to an array of `submitCount` valid VkSubmitInfo structures

- VUID-vkQueueSubmit-fence-parameter
  If `fence` is not VK_NULL_HANDLE, `fence` must be a valid VkFence handle

- VUID-vkQueueSubmit-commonparent
  Both of `fence`, and `queue` that are valid handles of non-ignored parameters must have been created, allocated, or retrieved from the same VkDevice

Host Synchronization
