present_state

D3D12_RESOURCE_STATES vkd3d_image_resource_create_info::present_state

This field specifies how to handle resource state D3D12_RESOURCE_STATE_PRESENT for the resource. Notice that on D3D12 there is no difference between D3D12_RESOURCE_STATE_COMMON and D3D12_RESOURCE_STATE_PRESENT (they have the same value), while on Vulkan two different layouts are used (VK_IMAGE_LAYOUT_GENERAL and VK_IMAGE_LAYOUT_PRESENT_SRC_KHR).

• When flag VKD3D_RESOURCE_PRESENT_STATE_TRANSITION is not specified, field present_state is ignored and resource state D3D12_RESOURCE_STATE_COMMON/_PRESENT is mapped to VK_IMAGE_LAYOUT_GENERAL; this is useful for non-swapchain resources.
• Otherwise, when present_state is D3D12_RESOURCE_STATE_PRESENT/_COMMON, resource state D3D12_RESOURCE_STATE_COMMON/_PRESENT is mapped to VK_IMAGE_LAYOUT_PRESENT_SRC_KHR; this is useful for swapchain resources that are directly backed by a Vulkan swapchain image.
• Otherwise, resource state D3D12_RESOURCE_STATE_COMMON/_PRESENT is treated as resource state present_state; this is useful for swapchain resources that backed by a Vulkan non-swapchain image, which the client will likely consume with a copy or drawing operation at presentation time.
