C Specification
The VkPhysicalDeviceSwapchainMaintenance1FeaturesEXT structure is
defined as:
// Provided by VK_EXT_swapchain_maintenance1
typedef struct VkPhysicalDeviceSwapchainMaintenance1FeaturesEXT {
VkStructureType sType;
void* pNext;
VkBool32 swapchainMaintenance1;
} VkPhysicalDeviceSwapchainMaintenance1FeaturesEXT;Description
-
sTypeis the type of this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
swapchainMaintenance1indicates that the implementation supports the following:-
VkSwapchainPresentFenceInfoEXT, specifying a fence that is signaled when the resources associated with a present operation can be safely destroyed.
-
VkSwapchainPresentModesCreateInfoEXT and VkSwapchainPresentModeInfoEXT, allowing the swapchain to switch present modes without a need for recreation.
-
VkSwapchainPresentScalingCreateInfoEXT, specifying the scaling behavior of the swapchain in presence of window resizing.
-
The
VK_SWAPCHAIN_CREATE_DEFERRED_MEMORY_ALLOCATION_BIT_EXTflag, allowing the implementation to defer the allocation of swapchain image memory until first acquisition. -
vkReleaseSwapchainImagesEXT, allowing acquired swapchain images to be released without presenting them.
-
If the VkPhysicalDeviceSwapchainMaintenance1FeaturesEXT 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.
VkPhysicalDeviceSwapchainMaintenance1FeaturesEXT can also be used in the pNext chain of
VkDeviceCreateInfo to selectively enable these features.
