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 isVK_TRUE
,VK_ACCESS_COLOR_ATTACHMENT_READ_NONCOHERENT_BIT_EXT
is treated the same asVK_ACCESS_COLOR_ATTACHMENT_READ_BIT
, and advanced blending needs no additional synchronization over basic blending. If this isVK_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.
