C Specification

To determine the sparse memory requirements for an image resource without creating an object, call:

// Provided by VK_KHR_maintenance4
void vkGetDeviceImageSparseMemoryRequirementsKHR(
    VkDevice                                    device,
    const VkDeviceImageMemoryRequirementsKHR*   pInfo,
    uint32_t*                                   pSparseMemoryRequirementCount,
    VkSparseImageMemoryRequirements2*           pSparseMemoryRequirements);

Parameters

  • device is the logical device intended to own the image.

  • pInfo is a pointer to a VkDeviceImageMemoryRequirementsKHR 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)
  • VUID-vkGetDeviceImageSparseMemoryRequirementsKHR-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkGetDeviceImageSparseMemoryRequirementsKHR-pInfo-parameter
    pInfo must be a valid pointer to a valid VkDeviceImageMemoryRequirementsKHR structure

  • VUID-vkGetDeviceImageSparseMemoryRequirementsKHR-pSparseMemoryRequirementCount-parameter
    pSparseMemoryRequirementCount must be a valid pointer to a uint32_t value

  • VUID-vkGetDeviceImageSparseMemoryRequirementsKHR-pSparseMemoryRequirements-parameter
    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
