VkCopyMemoryToMicromapInfoEXT(3)

# VkCopyMemoryToMicromapInfoEXT(3) Manual Page

## Name

VkCopyMemoryToMicromapInfoEXT - Parameters for deserializing a micromap

## C Specification

The `VkCopyMemoryToMicromapInfoEXT` structure is defined as:

    // Provided by VK_EXT_opacity_micromap
    typedef struct VkCopyMemoryToMicromapInfoEXT {
        VkStructureType                  sType;
        const void*                      pNext;
        VkDeviceOrHostAddressConstKHR    src;
        VkMicromapEXT                    dst;
        VkCopyMicromapModeEXT            mode;
    } VkCopyMemoryToMicromapInfoEXT;

## Members

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

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

- `src` is the device or host address of memory containing the source data for the copy.

- `dst` is the target micromap for the copy.

- `mode` is a VkCopyMicromapModeEXT value specifying additional operations to perform during the copy.

## Description

Valid Usage

- VUID-VkCopyMemoryToMicromapInfoEXT-src-07547
  The source memory pointed to by `src` must contain data previously serialized using vkCmdCopyMicromapToMemoryEXT

- VUID-VkCopyMemoryToMicromapInfoEXT-mode-07548
  `mode` must be VK_COPY_MICROMAP_MODE_DESERIALIZE_EXT

- VUID-VkCopyMemoryToMicromapInfoEXT-src-07549
  The data in `src` must have a format compatible with the destination physical device as returned by vkGetDeviceMicromapCompatibilityEXT

- VUID-VkCopyMemoryToMicromapInfoEXT-dst-07550
  `dst` must have been created with a `size` greater than or equal to that used to serialize the data in `src`

Valid Usage (Implicit)

- VUID-VkCopyMemoryToMicromapInfoEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_COPY_MEMORY_TO_MICROMAP_INFO_EXT

- VUID-VkCopyMemoryToMicromapInfoEXT-pNext-pNext
  `pNext` must be `NULL`

- VUID-VkCopyMemoryToMicromapInfoEXT-dst-parameter
  `dst` must be a valid VkMicromapEXT handle

- VUID-VkCopyMemoryToMicromapInfoEXT-mode-parameter
  `mode` must be a valid VkCopyMicromapModeEXT value
