VkPhysicalDeviceImageDrmFormatModifierInfoEXT

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:

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.
