Vulkan Backend

FidelityFX SDK native backend implementation for Vulkan.

Functions

ffxGetScratchMemorySizeVK

FFX_API size_t ffxGetScratchMemorySizeVK(VkPhysicalDevice physicalDevice, size_t maxContexts)

Query how much memory is required for the Vulkan backend’s scratch buffer.

Returns: The size (in bytes) of the required scratch memory buffer for the VK backend.

Parameters:

  • physicalDevice (VkPhysicalDevice) – [in] A pointer to the VkPhysicalDevice device.
  • maxContexts (size_t) – [in] The maximum number of simultaneous effect contexts that will share the backend. (Note that some effects contain internal contexts which count towards this maximum)

Returns: FFX_API size_t

ffxGetDeviceVK

FFX_API FfxDevice ffxGetDeviceVK(VkDeviceContext *vkDeviceContext)

Create a FfxDevice from a VkDevice.

Returns: An abstract FidelityFX device.

Parameters:

  • vkDeviceContext (VkDeviceContext *) – [in] A pointer to a VKDeviceContext that holds all needed information

Returns: FFX_API FfxDevice

ffxGetInterfaceVK

FFX_API FfxErrorCode ffxGetInterfaceVK(FfxInterface *backendInterface, FfxDevice device, void *scratchBuffer, size_t scratchBufferSize, size_t maxContexts)

Populate an interface with pointers for the VK backend.

Parameters:

  • backendInterface (FfxInterface *) – [out] A pointer to a FfxInterface structure to populate with pointers.
  • device (FfxDevice) – [in] A pointer to the VkDevice device.
  • scratchBuffer (void *) – [in] A pointer to a buffer of memory which can be used by the DirectX(R)12 backend.
  • scratchBufferSize (size_t) – [in] The size (in bytes) of the buffer pointed to by scratchBuffer.
  • maxContexts (size_t) – [in] The maximum number of simultaneous effect contexts that will share the backend. (Note that some effects contain internal contexts which count towards this maximum)

Returns: FFX_API FfxErrorCode
