# VkDrmFormatModifierPropertiesList2EXT(3) Manual Page

## Name

VkDrmFormatModifierPropertiesList2EXT - Structure specifying the list of DRM format modifiers supported for a format

Loading… please wait.

## C Specification

The list of Linux DRM format modifiers compatible with a VkFormat can be obtained by adding a VkDrmFormatModifierPropertiesList2EXT structure to the `pNext` chain of VkFormatProperties2.

The VkDrmFormatModifierPropertiesList2EXT structure is defined as:

    // Provided by VK_EXT_image_drm_format_modifier with VK_KHR_format_feature_flags2 or VK_VERSION_1_3
    typedef struct VkDrmFormatModifierPropertiesList2EXT {
        VkStructureType                       sType;
        void*                                 pNext;
        uint32_t                              drmFormatModifierCount;
        VkDrmFormatModifierProperties2EXT*    pDrmFormatModifierProperties;
    } VkDrmFormatModifierPropertiesList2EXT;

## Members

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

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

- `drmFormatModifierCount` is an inout parameter related to the number of modifiers compatible with the `format`, as described below.

- `pDrmFormatModifierProperties` is either `NULL` or a pointer to an array of VkDrmFormatModifierProperties2EXT structures.

## Description

If `pDrmFormatModifierProperties` is `NULL`, the number of modifiers compatible with the queried `format` is returned in `drmFormatModifierCount`. Otherwise, the application must set `drmFormatModifierCount` to the length of the array `pDrmFormatModifierProperties`; the function will write at most `drmFormatModifierCount` elements to the array, and will return in `drmFormatModifierCount` the number of elements written.

Among the elements in array `pDrmFormatModifierProperties`, each returned `drmFormatModifier` must be unique.

Among the elements in array `pDrmFormatModifierProperties`, the bits reported in `drmFormatModifierTilingFeatures` must include the bits reported in the corresponding element of `VkDrmFormatModifierPropertiesListEXT`::`pDrmFormatModifierProperties`.

Valid Usage (Implicit)

- VUID-VkDrmFormatModifierPropertiesList2EXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_DRM_FORMAT_MODIFIER_PROPERTIES_LIST_2_EXT`
