# VkPhysicalDeviceBlendOperationAdvancedFeaturesEXT(3) Manual Page

## Name

VkPhysicalDeviceBlendOperationAdvancedFeaturesEXT - Structure describing advanced blending features that can be supported by an implementation

## C Specification

The `VkPhysicalDeviceBlendOperationAdvancedFeaturesEXT` structure is defined as:

    typedef struct VkPhysicalDeviceBlendOperationAdvancedFeaturesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           advancedBlendCoherentOperations;
    } VkPhysicalDeviceBlendOperationAdvancedFeaturesEXT;

## Members

The members of the `VkPhysicalDeviceBlendOperationAdvancedFeaturesEXT` structure describe the following features:

## Description

- `advancedBlendCoherentOperations` specifies whether blending using advanced blend operations is guaranteed to execute atomically and in primitive order. If this is `VK_TRUE`, `VK_ACCESS_COLOR_ATTACHMENT_READ_NONCOHERENT_BIT_EXT` is treated the same as `VK_ACCESS_COLOR_ATTACHMENT_READ_BIT`, and advanced blending needs no additional synchronization over basic blending. If this is `VK_FALSE`, then memory dependencies are required to guarantee order between two advanced blending operations that occur on the same sample.

If the `VkPhysicalDeviceBlendOperationAdvancedFeaturesEXT` structure is included in the `pNext` chain of VkPhysicalDeviceFeatures2, it is filled with values indicating whether each feature is supported. `VkPhysicalDeviceBlendOperationAdvancedFeaturesEXT` can also be included in the `pNext` chain of VkDeviceCreateInfo to enable the features.

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_BLEND_OPERATION_ADVANCED_FEATURES_EXT`
