Description

This extension adds support for performing copies between memory and image regions using indirect parameters that are read by the device from a buffer during execution. This functionality may be useful for performing copies where the copy parameters are not known during the command buffer creation time.

Synopsis

Documentation

cmdCopyMemoryIndirectNV Source #

Arguments

:: forall io. MonadIO io 
=> CommandBuffer

commandBuffer is the command buffer into which the command will be recorded.

-> ("copyBufferAddress" ::: DeviceAddress)

copyBufferAddress is the buffer address specifying the copy parameters. This buffer is laid out in memory as an array of CopyMemoryIndirectCommandNV structures.

-> ("copyCount" ::: Word32)

copyCount is the number of copies to execute, and can be zero.

-> ("stride" ::: Word32)

stride is the stride in bytes between successive sets of copy parameters.

-> io () 

vkCmdCopyMemoryIndirectNV - Copy data between memory regions

Description

Each region read from copyBufferAddress is copied from the source region to the specified destination region. The results are undefined if any of the source and destination regions overlap in memory.

Valid Usage

Valid Usage (Implicit)

  • commandBuffer must be in the recording state
  • The CommandPool that commandBuffer was allocated from must support transfer, graphics, or compute operations
  • This command must only be called outside of a render pass instance
  • This command must only be called outside of a video coding scope

Host Synchronization

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

cmdCopyMemoryToImageIndirectNV Source #

Arguments

:: forall io. MonadIO io 
=> CommandBuffer

commandBuffer is the command buffer into which the command will be recorded.

-> ("copyBufferAddress" ::: DeviceAddress)

copyBufferAddress is the buffer address specifying the copy parameters. This buffer is laid out in memory as an array of CopyMemoryToImageIndirectCommandNV structures.

-> ("stride" ::: Word32)

stride is the byte stride between successive sets of copy parameters.

-> ("dstImage" ::: Image)

dstImage is the destination image.

-> ("dstImageLayout" ::: ImageLayout)

dstImageLayout is the layout of the destination image subresources for the copy.

-> ("imageSubresources" ::: Vector ImageSubresourceLayers)

pImageSubresources is a pointer to an array of size copyCount of ImageSubresourceLayers used to specify the specific image subresource of the destination image data for that copy.

-> io () 

vkCmdCopyMemoryToImageIndirectNV - Copy data from a memory region into an image

Description

Each region in copyBufferAddress is copied from the source memory region to an image region in the destination image. If the destination image is of type IMAGE_TYPE_3D, the starting slice and number of slices to copy are specified in pImageSubresources::baseArrayLayer and pImageSubresources::layerCount respectively. The copy must be performed on a queue that supports indirect copy operations, see PhysicalDeviceCopyMemoryIndirectPropertiesNV.

Valid Usage

  • dstImage must not be a protected image
  • The aspectMask member for every subresource in pImageSubresources must only have a single bit set
  • The image region specified by each element in copyBufferAddress must be a region that is contained within dstImage
  • dstImage must have been created with IMAGE_USAGE_TRANSFER_DST_BIT usage flag
  • If dstImage is non-sparse then it must be bound completely and contiguously to a single DeviceMemory object
  • dstImage must have a sample count equal to SAMPLE_COUNT_1_BIT
  • dstImageLayout must specify the layout of the image subresources of dstImage at the time this command is executed on a Device
  • dstImageLayout must be IMAGE_LAYOUT_TRANSFER_DST_OPTIMAL, IMAGE_LAYOUT_SHARED_PRESENT_KHR, or IMAGE_LAYOUT_GENERAL
  • The specified mipLevel of each region must be less than the mipLevels specified in ImageCreateInfo when dstImage was created
  • If the maintenance5 feature is not enabled, layerCount must not be REMAINING_ARRAY_LAYERS
  • If layerCount is not REMAINING_ARRAY_LAYERS, the specified baseArrayLayer + layerCount of each region must be less than or equal to the arrayLayers specified in ImageCreateInfo when dstImage was created
  • The imageOffset and imageExtent members of each region must respect the image transfer granularity requirements of commandBuffer’s command pool’s queue family, as described in QueueFamilyProperties
  • dstImage must not have been created with flags containing IMAGE_CREATE_SUBSAMPLED_BIT_EXT
  • If the queue family used to create the CommandPool which commandBuffer was allocated from does not support QUEUE_GRAPHICS_BIT, for each region, the aspectMask member of pImageSubresources must not be IMAGE_ASPECT_DEPTH_BIT or IMAGE_ASPECT_STENCIL_BIT
  • For each region in copyBufferAddress, imageOffset.y and (imageExtent.height + imageOffset.y) must both be greater than or equal to 0 and less than or equal to the height of the specified subresource
  • offset must be 4 byte aligned
  • stride must be a multiple of 4 and must be greater than or equal to sizeof(CopyMemoryToImageIndirectCommandNV)

Valid Usage (Implicit)

  • dstImage must be a valid Image handle
  • dstImageLayout must be a valid ImageLayout value
  • pImageSubresources must be a valid pointer to an array of copyCount valid ImageSubresourceLayers structures
  • commandBuffer must be in the recording state
  • The CommandPool that commandBuffer was allocated from must support transfer, graphics, or compute operations
  • This command must only be called outside of a render pass instance
  • This command must only be called outside of a video coding scope
  • copyCount must be greater than 0
  • Both of commandBuffer, and dstImage must have been created, allocated, or retrieved from the same Device

Host Synchronization

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

Fields

  • srcAddress :: DeviceAddress

    srcAddress is the starting address of the source device memory to copy from.

  • bufferRowLength :: Word32

    bufferRowLength and bufferImageHeight specify in texels a subregion of a larger two- or three-dimensional image in buffer memory, and control the addressing calculations. If either of these values is zero, that aspect of the buffer memory is considered to be tightly packed according to the imageExtent.

  • bufferImageHeight :: Word32
     
  • imageSubresource :: ImageSubresourceLayers

    imageSubresource is a ImageSubresourceLayers used to specify the specific image subresources of the image used for the destination image data, which must match the values specified in pImageSubresources parameter of cmdCopyMemoryToImageIndirectNV during command recording.

  • imageOffset :: Offset3D

    imageOffset selects the initial x, y, z offsets in texels of the sub-region of the destination image data.

  • imageExtent :: Extent3D

    imageExtent is the size in texels of the destination image in width, height and depth.

Members

This structure describes the following features:

Description

If the PhysicalDeviceCopyMemoryIndirectFeaturesNV structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. PhysicalDeviceCopyMemoryIndirectFeaturesNV can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.
