C Specification

Bits which can be set in VkSwapchainCreateInfoKHR::flags, specifying parameters of swapchain creation, are:

// Provided by VK_KHR_swapchain
typedef enum VkSwapchainCreateFlagBitsKHR {
  // Provided by VK_VERSION_1_1 with VK_KHR_swapchain, VK_KHR_device_group with VK_KHR_swapchain
    VK_SWAPCHAIN_CREATE_SPLIT_INSTANCE_BIND_REGIONS_BIT_KHR = 0x00000001,
  // Provided by VK_VERSION_1_1 with VK_KHR_swapchain
    VK_SWAPCHAIN_CREATE_PROTECTED_BIT_KHR = 0x00000002,
  // Provided by VK_KHR_swapchain_mutable_format
    VK_SWAPCHAIN_CREATE_MUTABLE_FORMAT_BIT_KHR = 0x00000004,
  // Provided by VK_EXT_swapchain_maintenance1
    VK_SWAPCHAIN_CREATE_DEFERRED_MEMORY_ALLOCATION_BIT_EXT = 0x00000008,
} VkSwapchainCreateFlagBitsKHR;

Description

  • VK_SWAPCHAIN_CREATE_SPLIT_INSTANCE_BIND_REGIONS_BIT_KHR specifies that images created from the swapchain (i.e. with the swapchain member of VkImageSwapchainCreateInfoKHR set to this swapchain’s handle) must use VK_IMAGE_CREATE_SPLIT_INSTANCE_BIND_REGIONS_BIT.

  • VK_SWAPCHAIN_CREATE_PROTECTED_BIT_KHR specifies that images created from the swapchain are protected images.

  • VK_SWAPCHAIN_CREATE_MUTABLE_FORMAT_BIT_KHR specifies that the images of the swapchain can be used to create a VkImageView with a different format than what the swapchain was created with. The list of allowed image view formats is specified by adding a VkImageFormatListCreateInfo structure to the pNext chain of VkSwapchainCreateInfoKHR. In addition, this flag also specifies that the swapchain can be created with usage flags that are not supported for the format the swapchain is created with but are supported for at least one of the allowed image view formats.

  • VK_SWAPCHAIN_CREATE_DEFERRED_MEMORY_ALLOCATION_BIT_EXT specifies that the implementation may defer allocation of memory associated with each swapchain image until its index is to be returned from vkAcquireNextImageKHR or vkAcquireNextImage2KHR for the first time.
