C Specification

To query sparse memory requirements for an image, call:

void vkGetImageSparseMemoryRequirements2(
    VkDevice                                    device,
    const VkImageSparseMemoryRequirementsInfo2* pInfo,
    uint32_t*                                   pSparseMemoryRequirementCount,
    VkSparseImageMemoryRequirements2*           pSparseMemoryRequirements);

or the equivalent command

void vkGetImageSparseMemoryRequirements2KHR(
    VkDevice                                    device,
    const VkImageSparseMemoryRequirementsInfo2* pInfo,
    uint32_t*                                   pSparseMemoryRequirementCount,
    VkSparseImageMemoryRequirements2*           pSparseMemoryRequirements);

Parameters

  • device is the logical device that owns the image.

  • pInfo is a pointer to an instance of the VkImageSparseMemoryRequirementsInfo2 structure containing parameters required for the memory requirements query.

  • pSparseMemoryRequirementCount is a pointer to an integer related to the number of sparse memory requirements available or queried, as described below.

  • pSparseMemoryRequirements is either NULL or a pointer to an array of VkSparseImageMemoryRequirements2 structures.

Description

Valid Usage (Implicit)
  • device must be a valid VkDevice handle

  • pInfo must be a valid pointer to a valid VkImageSparseMemoryRequirementsInfo2 structure

  • 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 VkSparseImageMemoryRequirements2 structures
