VkBindSparseInfo - Structure specifying a sparse binding operation

Loading… please wait.

## C Specification

The `VkBindSparseInfo` structure is defined as:

    // Provided by VK_VERSION_1_0
    typedef struct VkBindSparseInfo {
        VkStructureType                             sType;
        const void*                                 pNext;
        uint32_t                                    waitSemaphoreCount;
        const VkSemaphore*                          pWaitSemaphores;
        uint32_t                                    bufferBindCount;
        const VkSparseBufferMemoryBindInfo*         pBufferBinds;
        uint32_t                                    imageOpaqueBindCount;
        const VkSparseImageOpaqueMemoryBindInfo*    pImageOpaqueBinds;
        uint32_t                                    imageBindCount;
        const VkSparseImageMemoryBindInfo*          pImageBinds;
        uint32_t                                    signalSemaphoreCount;
        const VkSemaphore*                          pSignalSemaphores;
    } VkBindSparseInfo;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `waitSemaphoreCount` is the number of semaphores upon which to wait before executing the sparse binding operations for the batch.

- `pWaitSemaphores` is a pointer to an array of semaphores upon which to wait on before the sparse binding operations for this batch begin execution. If semaphores to wait on are provided, they define a semaphore wait operation.

- `bufferBindCount` is the number of sparse buffer bindings to perform in the batch.

- `pBufferBinds` is a pointer to an array of VkSparseBufferMemoryBindInfo structures.

- `imageOpaqueBindCount` is the number of opaque sparse image bindings to perform.

- `pImageOpaqueBinds` is a pointer to an array of VkSparseImageOpaqueMemoryBindInfo structures, indicating opaque sparse image bindings to perform.

- `imageBindCount` is the number of sparse image bindings to perform.

- `pImageBinds` is a pointer to an array of VkSparseImageMemoryBindInfo structures, indicating sparse image bindings to perform.

- `signalSemaphoreCount` is the number of semaphores to be signaled once the sparse binding operations specified by the structure have completed execution.

- `pSignalSemaphores` is a pointer to an array of semaphores which will be signaled when the sparse binding operations for this batch have completed execution. If semaphores to be signaled are provided, they define a semaphore signal operation.

## Description

Valid Usage

- VUID-VkBindSparseInfo-pWaitSemaphores-03246
  If any element of `pWaitSemaphores` or `pSignalSemaphores` was created with a VkSemaphoreType of `VK_SEMAPHORE_TYPE_TIMELINE` then the `pNext` chain must include a VkTimelineSemaphoreSubmitInfo structure

- VUID-VkBindSparseInfo-pNext-03247
  If the `pNext` chain of this structure includes a VkTimelineSemaphoreSubmitInfo structure and any element of `pWaitSemaphores` was created with a VkSemaphoreType of `VK_SEMAPHORE_TYPE_TIMELINE` then its `waitSemaphoreValueCount` member must equal `waitSemaphoreCount`

- VUID-VkBindSparseInfo-pNext-03248
  If the `pNext` chain of this structure includes a VkTimelineSemaphoreSubmitInfo structure and any element of `pSignalSemaphores` was created with a VkSemaphoreType of `VK_SEMAPHORE_TYPE_TIMELINE` then its `signalSemaphoreValueCount` member must equal `signalSemaphoreCount`

- VUID-VkBindSparseInfo-pSignalSemaphores-03249
  For each element of `pSignalSemaphores` created with a VkSemaphoreType of `VK_SEMAPHORE_TYPE_TIMELINE` the corresponding element of VkTimelineSemaphoreSubmitInfo::`pSignalSemaphoreValues` must have a value greater than the current value of the semaphore when the semaphore signal operation is executed

- VUID-VkBindSparseInfo-pWaitSemaphores-03250
  For each element of `pWaitSemaphores` created with a VkSemaphoreType of `VK_SEMAPHORE_TYPE_TIMELINE` the corresponding element of VkTimelineSemaphoreSubmitInfo::`pWaitSemaphoreValues` must have a value which does not differ from the current value of the semaphore or from the value of any outstanding semaphore wait or signal operation on that semaphore by more than `maxTimelineSemaphoreValueDifference`

- VUID-VkBindSparseInfo-pSignalSemaphores-03251
  For each element of `pSignalSemaphores` created with a VkSemaphoreType of `VK_SEMAPHORE_TYPE_TIMELINE` the corresponding element of VkTimelineSemaphoreSubmitInfo::`pSignalSemaphoreValues` must have a value which does not differ from the current value of the semaphore or from the value of any outstanding semaphore wait or signal operation on that semaphore by more than `maxTimelineSemaphoreValueDifference`

Valid Usage (Implicit)

- VUID-VkBindSparseInfo-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_BIND_SPARSE_INFO`

- VUID-VkBindSparseInfo-pNext-pNext
  Each `pNext` member of any structure (including this one) in the `pNext` chain must be either `NULL` or a pointer to a valid instance of VkDeviceGroupBindSparseInfo, VkFrameBoundaryEXT, or VkTimelineSemaphoreSubmitInfo

- VUID-VkBindSparseInfo-sType-unique
  The `sType` value of each structure in the `pNext` chain must be unique

- VUID-VkBindSparseInfo-pWaitSemaphores-parameter
  If `waitSemaphoreCount` is not `0`, `pWaitSemaphores` must be a valid pointer to an array of `waitSemaphoreCount` valid VkSemaphore handles

- VUID-VkBindSparseInfo-pBufferBinds-parameter
  If `bufferBindCount` is not `0`, `pBufferBinds` must be a valid pointer to an array of `bufferBindCount` valid VkSparseBufferMemoryBindInfo structures

- VUID-VkBindSparseInfo-pImageOpaqueBinds-parameter
  If `imageOpaqueBindCount` is not `0`, `pImageOpaqueBinds` must be a valid pointer to an array of `imageOpaqueBindCount` valid VkSparseImageOpaqueMemoryBindInfo structures

- VUID-VkBindSparseInfo-pImageBinds-parameter
  If `imageBindCount` is not `0`, `pImageBinds` must be a valid pointer to an array of `imageBindCount` valid VkSparseImageMemoryBindInfo structures

- VUID-VkBindSparseInfo-pSignalSemaphores-parameter
  If `signalSemaphoreCount` is not `0`, `pSignalSemaphores` must be a valid pointer to an array of `signalSemaphoreCount` valid VkSemaphore handles

- VUID-VkBindSparseInfo-commonparent
  Both of the elements of `pSignalSemaphores`, and the elements of `pWaitSemaphores` that are valid handles of non-ignored parameters must have been created, allocated, or retrieved from the same VkDevice
