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 used in pNext chain of VkDeviceCreateInfo to enable the features.

Valid Usage (Implicit)
  • sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_BLEND_OPERATION_ADVANCED_FEATURES_EXT
