C Specification

To query the image capabilities that are compatible with a Linux DRM format modifier, set VkPhysicalDeviceImageFormatInfo2::tiling to VK_IMAGE_TILING_DRM_FORMAT_MODIFIER_EXT and add a VkPhysicalDeviceImageDrmFormatModifierInfoEXT structure to the pNext chain of VkPhysicalDeviceImageFormatInfo2.

The VkPhysicalDeviceImageDrmFormatModifierInfoEXT structure is defined as:

// Provided by VK_EXT_image_drm_format_modifier
typedef struct VkPhysicalDeviceImageDrmFormatModifierInfoEXT {
    VkStructureType    sType;
    const void*        pNext;
    uint64_t           drmFormatModifier;
    VkSharingMode      sharingMode;
    uint32_t           queueFamilyIndexCount;
    const uint32_t*    pQueueFamilyIndices;
} VkPhysicalDeviceImageDrmFormatModifierInfoEXT;


  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • drmFormatModifier is the image’s Linux DRM format modifier, corresponding to VkImageDrmFormatModifierExplicitCreateInfoEXT::modifier or to VkImageDrmFormatModifierListCreateInfoEXT::pModifiers.

  • sharingMode specifies how the image will be accessed by multiple queue families.

  • queueFamilyIndexCount is the number of entries in the pQueueFamilyIndices array.

  • pQueueFamilyIndices is a pointer to an array of queue families that will access the image. It is ignored if sharingMode is not VK_SHARING_MODE_CONCURRENT.


If the drmFormatModifier is incompatible with the parameters specified in VkPhysicalDeviceImageFormatInfo2 and its pNext chain, then vkGetPhysicalDeviceImageFormatProperties2 returns VK_ERROR_FORMAT_NOT_SUPPORTED. The implementation must support the query of any drmFormatModifier, including unknown and invalid modifier values.

Valid Usage
  • VUID-VkPhysicalDeviceImageDrmFormatModifierInfoEXT-sharingMode-02314
    If sharingMode is VK_SHARING_MODE_CONCURRENT, then pQueueFamilyIndices must be a valid pointer to an array of queueFamilyIndexCount uint32_t values

  • VUID-VkPhysicalDeviceImageDrmFormatModifierInfoEXT-sharingMode-02315
    If sharingMode is VK_SHARING_MODE_CONCURRENT, then queueFamilyIndexCount must be greater than 1

  • VUID-VkPhysicalDeviceImageDrmFormatModifierInfoEXT-sharingMode-02316
    If sharingMode is VK_SHARING_MODE_CONCURRENT, each element of pQueueFamilyIndices must be unique and must be less than the pQueueFamilyPropertyCount returned by vkGetPhysicalDeviceQueueFamilyProperties2 for the physicalDevice that was used to create device

Valid Usage (Implicit)
  • VUID-VkPhysicalDeviceImageDrmFormatModifierInfoEXT-sType-sType

  • VUID-VkPhysicalDeviceImageDrmFormatModifierInfoEXT-sharingMode-parameter
    sharingMode must be a valid VkSharingMode value
