vkGetImageSparseMemoryRequirements - Query the memory requirements for a sparse image

Description

If pSparseMemoryRequirements is NULL, then the number of sparse memory requirements available is returned in pSparseMemoryRequirementCount. Otherwise, pSparseMemoryRequirementCount must point to a variable set by the user to the number of elements in the pSparseMemoryRequirements array, and on return the variable is overwritten with the number of structures actually written to pSparseMemoryRequirements. If pSparseMemoryRequirementCount is less than the number of sparse memory requirements available, at most pSparseMemoryRequirementCount structures will be written.

If the image was not created with IMAGE_CREATE_SPARSE_RESIDENCY_BIT then pSparseMemoryRequirementCount will be set to zero and pSparseMemoryRequirements will not be written to.

Note

It is legal for an implementation to report a larger value in MemoryRequirements::size than would be obtained by adding together memory sizes for all SparseImageMemoryRequirements returned by getImageSparseMemoryRequirements. This may occur when the implementation requires unused padding in the address range describing the resource.

Valid Usage (Implicit)

• device must be a valid Device handle

• image must be a valid Image handle
• pSparseMemoryRequirementCount must be a valid pointer to a uint32_t value
• If the value referenced by pSparseMemoryRequirementCount is not 0, and pSparseMemoryRequirements is not NULL, pSparseMemoryRequirements must be a valid pointer to an array of pSparseMemoryRequirementCount SparseImageMemoryRequirements structures
• image must have been created, allocated, or retrieved from device

vkGetPhysicalDeviceSparseImageFormatProperties - Retrieve properties of an image format applied to sparse images

Description

If pProperties is NULL, then the number of sparse format properties available is returned in pPropertyCount. Otherwise, pPropertyCount must point to a variable set by the user to the number of elements in the pProperties array, and on return the variable is overwritten with the number of structures actually written to pProperties. If pPropertyCount is less than the number of sparse format properties available, at most pPropertyCount structures will be written.

If IMAGE_CREATE_SPARSE_RESIDENCY_BIT is not supported for the given arguments, pPropertyCount will be set to zero upon return, and no data will be written to pProperties.

Multiple aspects are returned for depth/stencil images that are implemented as separate planes by the implementation. The depth and stencil data planes each have unique SparseImageFormatProperties data.

Depth/stencil images with depth and stencil data interleaved into a single plane will return a single SparseImageFormatProperties structure with the aspectMask set to IMAGE_ASPECT_DEPTH_BIT | IMAGE_ASPECT_STENCIL_BIT.

Valid Usage

• samples must be a bit value that is set in ImageFormatProperties::sampleCounts returned by getPhysicalDeviceImageFormatProperties with format, type, tiling, and usage equal to those in this command and flags equal to the value that is set in ImageCreateInfo::flags when the image is created

Valid Usage (Implicit)

• physicalDevice must be a valid PhysicalDevice handle

• format must be a valid Format value
• type must be a valid ImageType value
• samples must be a valid SampleCountFlagBits value
• usage must be a valid combination of ImageUsageFlagBits values
• usage must not be 0
• tiling must be a valid ImageTiling value
• pPropertyCount must be a valid pointer to a uint32_t value
• If the value referenced by pPropertyCount is not 0, and pProperties is not NULL, pProperties must be a valid pointer to an array of pPropertyCount SparseImageFormatProperties structures

vkQueueBindSparse - Bind device memory to a sparse resource object

Description

queueBindSparse is a queue submission command, with each batch defined by an element of pBindInfo as a BindSparseInfo 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 queueBindSparse 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 NULL_HANDLE, fence must be unsignaled

• If fence is not 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 wait operation referring to a binary semaphore defined by any element of the pWaitSemaphores member of any element of pBindInfo executes on queue, there must be no other queues waiting on the same semaphore
• All elements of the pWaitSemaphores member of all elements of pBindInfo created with a SemaphoreType of SEMAPHORE_TYPE_BINARY must reference a semaphore signal operation that has been submitted for execution and any semaphore signal operations on which it depends (if any) must have also been submitted for execution

Valid Usage (Implicit)

• queue must be a valid Queue handle

• If bindInfoCount is not 0, pBindInfo must be a valid pointer to an array of bindInfoCount valid BindSparseInfo structures
• If fence is not NULL_HANDLE, fence must be a valid Fence handle
• The queue must support sparse binding operations
• Both of fence, and queue that are valid handles of non-ignored parameters must have been created, allocated, or retrieved from the same Device

Host Synchronization

• Host access to queue must be externally synchronized

• Host access to fence must be externally synchronized

VkSparseMemoryBind - Structure specifying a sparse memory bind operation

Description

The binding range [resourceOffset, resourceOffset + size) has different constraints based on flags. If flags contains SPARSE_MEMORY_BIND_METADATA_BIT, the binding range must be within the mip tail region of the metadata aspect. This metadata region is defined by:

• metadataRegion = [base, base + imageMipTailSize)
• base = imageMipTailOffset + imageMipTailStride × n

and imageMipTailOffset, imageMipTailSize, and imageMipTailStride values are from the SparseImageMemoryRequirements corresponding to the metadata aspect of the image, and n is a valid array layer index for the image,

imageMipTailStride is considered to be zero for aspects where SparseImageMemoryRequirements::formatProperties.flags contains SPARSE_IMAGE_FORMAT_SINGLE_MIPTAIL_BIT.

If flags does not contain SPARSE_MEMORY_BIND_METADATA_BIT, the binding range must be within the range [0,MemoryRequirements::size).

Valid Usage

• If memory is not NULL_HANDLE, memory and memoryOffset must match the memory requirements of the resource, as described in section https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#resources-association

• If memory is not NULL_HANDLE, memory must not have been created with a memory type that reports MEMORY_PROPERTY_LAZILY_ALLOCATED_BIT bit set
• size must be greater than 0
• resourceOffset must be less than the size of the resource
• size must be less than or equal to the size of the resource minus resourceOffset
• memoryOffset must be less than the size of memory
• size must be less than or equal to the size of memory minus memoryOffset
• If memory was created with ExportMemoryAllocateInfo::handleTypes not equal to 0, at least one handle type it contained must also have been set in ExternalMemoryBufferCreateInfo::handleTypes or ExternalMemoryImageCreateInfo::handleTypes when the resource was created
• If memory was created by a memory import operation, the external handle type of the imported memory must also have been set in ExternalMemoryBufferCreateInfo::handleTypes or ExternalMemoryImageCreateInfo::handleTypes when the resource was created

Valid Usage (Implicit)

• If memory is not NULL_HANDLE, memory must be a valid DeviceMemory handle
