Description

This extension adds support for synchronizing corresponding presentation requests across multiple swapchains using the present barrier.

New Structures

New Enum Constants

Issues

1) Is there a query interface to check if a swapchain is using the present barrier?

RESOLVED. There is no such query interface. When creating a swapchain, an application can specify to use the present barrier, and if the swapchain is created successfully, this swapchain will be using the present barrier.

2) Do we need an extra interface to set up the present barrier across distributed systems?

RESOLVED. If the required hardware is presented in the system, and all settings for the physical synchronization with other systems are set up, an implementation manages the configuration automatically when creating a swapchain, without any extra calls from the application.

Synopsis

Documentation

data PhysicalDevicePresentBarrierFeaturesNV Source #

VkPhysicalDevicePresentBarrierFeaturesNV - Structure indicating support for VK_NV_present_barrier extension

Members

This structure describes the following feature:

Description

If the PhysicalDevicePresentBarrierFeaturesNV 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. PhysicalDevicePresentBarrierFeaturesNV can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

VK_NV_present_barrier, Bool32, StructureType

Constructors

PhysicalDevicePresentBarrierFeaturesNV 

Fields

  • presentBarrier :: Bool

    presentBarrier indicates that the implementation supports the present barrier feature.

data SurfaceCapabilitiesPresentBarrierNV Source #

VkSurfaceCapabilitiesPresentBarrierNV - Structure describing present barrier capabilities of a surface

Description

This structure can be included in the pNext chain of SurfaceCapabilities2KHR to determine support for present barrier access. If presentBarrierSupported is FALSE, it indicates that the present barrier feature is not obtainable for this surface.

Valid Usage (Implicit)

VK_NV_present_barrier, Bool32, StructureType

Constructors

SurfaceCapabilitiesPresentBarrierNV 

Fields

  • presentBarrierSupported :: Bool

    presentBarrierSupported is a boolean describing whether the surface is able to make use of the present barrier feature.

data SwapchainPresentBarrierCreateInfoNV Source #

VkSwapchainPresentBarrierCreateInfoNV - specify the present barrier membership of this swapchain

Description

If the pNext chain of SwapchainCreateInfoKHR does not include this structure, the default value for presentBarrierEnable is FALSE, meaning the swapchain does not request to use the present barrier. Additionally, when recreating a swapchain that was using the present barrier, and the pNext chain of SwapchainCreateInfoKHR does not include this structure, it means the swapchain will stop using the present barrier.
