Description

The VK_NN_vi_surface extension is an instance extension. It provides a mechanism to create a SurfaceKHR object (defined by the VK_KHR_surface extension) associated with an nn::vi::Layer.

Issues

1) Does VI need a way to query for compatibility between a particular physical device (and queue family?) and a specific VI display?

RESOLVED: No. It is currently always assumed that the device and display will always be compatible.

2) ViSurfaceCreateInfoNN::window is intended to store an nn::vi::NativeWindowHandle, but its declared type is a bare void* to store the window handle. Why the discrepancy?

RESOLVED: It is for C compatibility. The definition for the VI native window handle type is defined inside the nn::vi C++ namespace. This prevents its use in C source files. nn::vi::NativeWindowHandle is always defined to be void*, so this extension uses void* to match.

  1. :: MonadIO io
  2. => Instance

    instance is the instance with which to associate the surface.

  3. -> ViSurfaceCreateInfoNN

    pCreateInfo is a pointer to a ViSurfaceCreateInfoNN structure containing parameters affecting the creation of the surface object.

  4. -> "allocator" ::: Maybe AllocationCallbacks

    pAllocator is the allocator used for host memory allocated for the surface object when there is no more specific allocator available (see Memory Allocation).

vkCreateViSurfaceNN - Create a SurfaceKHR object for a VI layer

Description

During the lifetime of a surface created using a particular nn::vi::NativeWindowHandle, applications must not attempt to create another surface for the same nn::vi::Layer or attempt to connect to the same nn::vi::Layer through other platform mechanisms.

If the native window is created with a specified size, currentExtent will reflect that size. In this case, applications should use the same size for the swapchain’s imageExtent. Otherwise, the currentExtent will have the special value (0xFFFFFFFF, 0xFFFFFFFF), indicating that applications are expected to choose an appropriate size for the swapchain’s imageExtent (e.g., by matching the result of a call to nn::vi::GetDisplayResolution).

Valid Usage (Implicit)

  • instance must be a valid Instance handle

VkSurfaceKHR - Opaque handle to a surface object

Description

The VK_KHR_surface extension declares the SurfaceKHR object, and provides a function for destroying SurfaceKHR objects. Separate platform-specific extensions each provide a function for creating a SurfaceKHR object for the respective platform. From the application’s perspective this is an opaque handle, just like the handles of other Vulkan objects.
