allocateCommandBuffers :: forall io. MonadIO io => Device -> CommandBufferAllocateInfo -> io ("commandBuffers" ::: Vector CommandBuffer) Source #

vkAllocateCommandBuffers - Allocate command buffers from an existing command pool

Parameters

  • device is the logical device that owns the command pool.
  • pAllocateInfo is a pointer to a CommandBufferAllocateInfo structure describing parameters of the allocation.
  • pCommandBuffers is a pointer to an array of CommandBuffer handles in which the resulting command buffer objects are returned. The array must be at least the length specified by the commandBufferCount member of pAllocateInfo. Each allocated command buffer begins in the initial state.

Description

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

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 value referenced by pAllocateInfo->commandBufferCount must be greater than 0

Host Synchronization

  • Host access to pAllocateInfo->commandPool must be externally synchronized

Return Codes

Success
Failure

withCommandBuffers :: forall io r. MonadIO io => (io (Vector CommandBuffer) -> (Vector CommandBuffer -> io ()) -> r) -> Device -> CommandBufferAllocateInfo -> r Source #

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 first argument. To just extract the pair pass '(,)' as the first argument.

freeCommandBuffers :: forall io. MonadIO io => Device -> CommandPool -> ("commandBuffers" ::: Vector CommandBuffer) -> io () Source #

vkFreeCommandBuffers - Free command buffers

Parameters

  • device is the logical device that owns the command pool.
  • commandPool is the command pool from which the command buffers were allocated.
  • commandBufferCount is the length of the pCommandBuffers array.
  • pCommandBuffers is a pointer to an array of handles of command buffers to free.

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

  • 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

beginCommandBuffer :: forall a io. (PokeChain a, MonadIO io) => CommandBuffer -> CommandBufferBeginInfo a -> io () Source #

vkBeginCommandBuffer - Start recording a command buffer

Parameters

  • commandBuffer is the handle of the command buffer which is to be put in the recording state.
  • pBeginInfo points to a CommandBufferBeginInfo structure defining additional information about how the command buffer begins recording.

useCommandBuffer :: forall a io r. (PokeChain a, MonadIO io) => (io () -> io () -> r) -> CommandBuffer -> CommandBufferBeginInfo a -> r Source #

A convenience wrapper to make a compatible pair of calls to beginCommandBuffer and endCommandBuffer

To ensure that endCommandBuffer is always called: pass bracket_ (or the allocate function from your favourite resource management library) as the first argument. To just extract the pair pass '(,)' as the first argument.

Note that there is no inner resource

endCommandBuffer :: forall io. MonadIO io => CommandBuffer -> io () Source #

vkEndCommandBuffer - Finish recording a command buffer

Parameters

  • commandBuffer is the command buffer to complete recording.

Description

If there was an error during recording, the application will be notified by an unsuccessful return code returned by endCommandBuffer. If the application wishes to further use the command buffer, the command buffer must be reset. The command buffer must have been in the recording state, and is moved to the executable state.

Valid Usage

  • 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
  • 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

Valid Usage (Implicit)

Host Synchronization

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

vkResetCommandBuffer - Reset a command buffer to the initial state

Parameters

  • commandBuffer is the command buffer to reset. The command buffer can be in any state other than pending, and is moved into the initial state.

Description

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

CommandBufferInheritanceInfo 

Fields

  • next :: Chain es

    pNext is NULL or a pointer to an extension-specific structure.

  • renderPass :: RenderPass

    renderPass is a RenderPass object defining which render passes the CommandBuffer will be compatible with and can be executed within. If the CommandBuffer will not be executed within a render pass instance, renderPass is ignored.

  • subpass :: Word32

    subpass is the index of the subpass within the render pass instance that the CommandBuffer will be executed within. If the CommandBuffer will not be executed within a render pass instance, subpass is ignored.

  • framebuffer :: Framebuffer

    framebuffer optionally refers to the Framebuffer object that the CommandBuffer will be rendering to if it is executed within a render pass instance. It can be NULL_HANDLE if the framebuffer is not known, or if the CommandBuffer will not be executed within a render pass instance.

    Note

    Specifying the exact framebuffer that the secondary command buffer will be executed with may result in better performance at command buffer execution time.

  • occlusionQueryEnable :: Bool

    occlusionQueryEnable specifies whether the command buffer can be executed while an occlusion query is active in the primary command buffer. If this is TRUE, then this command buffer can be executed whether the primary command buffer has an occlusion query active or not. If this is FALSE, then the primary command buffer must not have an occlusion query active.

  • queryFlags :: QueryControlFlags

    queryFlags specifies the query flags that can be used by an active occlusion query in the primary command buffer when this secondary command buffer is executed. If this value includes the QUERY_CONTROL_PRECISE_BIT bit, then the active query can return boolean results or actual sample counts. If this bit is not set, then the active query must not use the QUERY_CONTROL_PRECISE_BIT bit.

  • pipelineStatistics :: QueryPipelineStatisticFlags

    pipelineStatistics is a bitmask of QueryPipelineStatisticFlagBits specifying the set of pipeline statistics that can be counted by an active query in the primary command buffer when this secondary command buffer is executed. If this value includes a given bit, then this command buffer can be executed whether the primary command buffer has a pipeline statistics query active that includes this bit or not. If this value excludes a given bit, then the active pipeline statistics query must not be from a query pool that counts that statistic.
