Vulkan.Core10.CommandBuffer

vkAllocateCommandBuffers - Allocate command buffers from an existing command pool

Description

allocateCommandBuffers can be used to allocate multiple command buffers. If the allocation of any of those command buffers fails, the implementation must free all successfully allocated command buffer objects from this command, set all entries of the pCommandBuffers array to NULL and return the error.

Filling pCommandBuffers with NULL values on failure is an exception to the default error behavior that output parameters will have undefined contents.

When command buffers are first allocated, they are in the initial state.

Valid Usage (Implicit)

• device must be a valid Device handle

• pAllocateInfo must be a valid pointer to a valid CommandBufferAllocateInfo structure

• pCommandBuffers must be a valid pointer to an array of pAllocateInfo->commandBufferCount CommandBuffer handles

• The device must have been created with at least 1 queue

• pAllocateInfo->commandBufferCount must be greater than 0

Return Codes

Success

• SUCCESS

Failure

• ERROR_OUT_OF_DEVICE_MEMORY

• ERROR_OUT_OF_HOST_MEMORY

• ERROR_UNKNOWN

• ERROR_VALIDATION_FAILED

A convenience wrapper to make a compatible pair of calls to allocateCommandBuffers and freeCommandBuffers

To ensure that freeCommandBuffers is always called: pass bracket (or the allocate function from your favourite resource management library) as the last argument. To just extract the pair pass (,) as the last argument.

vkFreeCommandBuffers - Free command buffers

Description

Any primary command buffer that is in the recording or executable state and has any element of pCommandBuffers recorded into it, becomes invalid.

Valid Usage

• All elements of pCommandBuffers must not be in the pending state

• pCommandBuffers must be a valid pointer to an array of commandBufferCount CommandBuffer handles, each element of which must either be a valid handle or NULL

Valid Usage (Implicit)

• device must be a valid Device handle

• commandPool must be a valid CommandPool handle

• commandBufferCount must be greater than 0

• commandPool must have been created, allocated, or retrieved from device

• Each element of pCommandBuffers that is a valid handle must have been created, allocated, or retrieved from commandPool

Host Synchronization

• Host access to commandPool must be externally synchronized

• Host access to each member of pCommandBuffers must be externally synchronized

VK_VERSION_1_0, CommandBuffer, CommandPool, Device

vkBeginCommandBuffer - Start recording a command buffer

Valid Usage

• commandBuffer must not be in the recording or pending state

• If commandBuffer was allocated from a CommandPool which did not have the COMMAND_POOL_CREATE_RESET_COMMAND_BUFFER_BIT flag set, commandBuffer must be in the initial state

• If commandBuffer is a secondary command buffer, the pInheritanceInfo member of pBeginInfo must be a valid CommandBufferInheritanceInfo structure

• If commandBuffer is a secondary command buffer and either the occlusionQueryEnable member of the pInheritanceInfo member of pBeginInfo is FALSE, or the occlusionQueryPrecise feature is not enabled, then pBeginInfo->pInheritanceInfo->queryFlags must not contain QUERY_CONTROL_PRECISE_BIT

Valid Usage (Implicit)

• commandBuffer must be a valid CommandBuffer handle

• pBeginInfo must be a valid pointer to a valid CommandBufferBeginInfo structure

Host Synchronization

• Host access to commandBuffer must be externally synchronized

Success

• SUCCESS

Failure

• ERROR_OUT_OF_DEVICE_MEMORY

• ERROR_OUT_OF_HOST_MEMORY

• ERROR_UNKNOWN

• ERROR_VALIDATION_FAILED

This function will call the supplied action between calls to beginCommandBuffer and endCommandBuffer

Note that endCommandBuffer is *not* called if an exception is thrown by the inner action.

vkEndCommandBuffer - Finish recording a command buffer

Description

The command buffer must have been in the recording state, and, if successful, is moved to the executable state.

If there was an error during recording, the application will be notified by an unsuccessful return code returned by endCommandBuffer, and the command buffer will be moved to the invalid state.

In case the application recorded one or more video encode operations into the command buffer, implementations may return the VK_ERROR_INVALID_VIDEO_STD_PARAMETERS_KHR error if any of the specified Video Std parameters do not adhere to the syntactic or semantic requirements of the used video compression standard, or if values derived from parameters according to the rules defined by the used video compression standard do not adhere to the capabilities of the video compression standard or the implementation.

Applications should not rely on the VK_ERROR_INVALID_VIDEO_STD_PARAMETERS_KHR error being returned by any command as a means to verify Video Std parameters, as implementations are not required to report the error in any specific set of cases.

Valid Usage

• commandBuffer must be in the recording state

• If commandBuffer is a primary command buffer, there must not be an active render pass instance

• All queries made active during the recording of commandBuffer must have been made inactive

• Conditional rendering must not be active

• There must be no video session object bound

• If commandBuffer is a secondary command buffer, there must not be an outstanding cmdBeginDebugUtilsLabelEXT command recorded to commandBuffer that has not previously been ended by a call to cmdEndDebugUtilsLabelEXT

• If commandBuffer is a secondary command buffer, there must not be an outstanding cmdDebugMarkerBeginEXT command recorded to commandBuffer that has not previously been ended by a call to cmdDebugMarkerEndEXT

• commandBuffer must not have any shader instrumentation active

Valid Usage (Implicit)

• commandBuffer must be a valid CommandBuffer handle

Host Synchronization

• Host access to commandBuffer must be externally synchronized

• Host access to the CommandPool that commandBuffer was allocated from must be externally synchronized

Return Codes

Success

• SUCCESS

Failure

• VK_ERROR_INVALID_VIDEO_STD_PARAMETERS_KHR

• ERROR_OUT_OF_DEVICE_MEMORY

• ERROR_OUT_OF_HOST_MEMORY

• ERROR_UNKNOWN

• ERROR_VALIDATION_FAILED

vkResetCommandBuffer - Reset a command buffer to the initial state

Description

Any primary command buffer that is in the recording or executable state and has commandBuffer recorded into it, becomes invalid.

• COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT specifies that each recording of the command buffer will only be submitted once, and the command buffer will be reset and recorded again between each submission.

• COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT specifies that a secondary command buffer is considered to be entirely inside a render pass. If this is a primary command buffer, then this bit is ignored.

• COMMAND_BUFFER_USAGE_SIMULTANEOUS_USE_BIT specifies that a command buffer can be resubmitted to any queue of the same queue family while it is in the pending state, and recorded into multiple primary command buffers.

Description

• COMMAND_BUFFER_RESET_RELEASE_RESOURCES_BIT specifies that most or all memory resources currently owned by the command buffer should be returned to the parent command pool. If this flag is not set, then the command buffer may hold onto memory resources and reuse them when recording commands. commandBuffer is moved to the initial state.
