Description

This extension significantly simplifies synchronization in Vulkan by removing the need for image layout transitions in most cases. In particular, it guarantees that using the IMAGE_LAYOUT_GENERAL layout everywhere possible is just as efficient as using the other layouts.

VkPhysicalDeviceUnifiedImageLayoutsFeaturesKHR - Structure describing whether the implementation provides unified image layouts

Members

This structure describes the following feature:

Description

If the PhysicalDeviceUnifiedImageLayoutsFeaturesKHR structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a Device with any features described by PhysicalDeviceUnifiedImageLayoutsFeaturesKHR, it must add an instance of the structure, with the desired feature members set to TRUE, to the pNext chain of DeviceCreateInfo when creating the Device.
