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
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
swapchainMaintenance1
indicates 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_EXT
flag, 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.
