VkPhysicalDeviceBlendOperationAdvancedFeaturesEXT

The VkPhysicalDeviceBlendOperationAdvancedFeaturesEXT structure is defined as:

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

This structure describes the following feature:

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• 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 the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by VkPhysicalDeviceBlendOperationAdvancedFeaturesEXT, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the pNext chain of VkDeviceCreateInfo when creating the VkDevice.
