Versions add the following features: // Version 0 - Initial. Doesn't support vk_icdGetInstanceProcAddr // or vk_icdNegotiateLoaderICDInterfaceVersion. // Version 1 - Add support for vk_icdGetInstanceProcAddr. // Version 2 - Add Loader/ICD Interface version negotiation // via vk_icdNegotiateLoaderICDInterfaceVersion. // Version 3 - Add ICD creation/destruction of KHR_surface objects. // Version 4 - Add unknown physical device extension querying via // vk_icdGetPhysicalDeviceProcAddr. // Version 5 - Tells ICDs that the loader is now paying attention to the // application version of Vulkan passed into the ApplicationInfo // structure during vkCreateInstance. This will tell the ICD // that if the loader is older, it should automatically fail a // call for any API version > 1.0. Otherwise, the loader will // manually determine if it can support the expected version. // Version 6 - Add support for vk_icdEnumerateAdapterPhysicalDevices. // Version 7 - If an ICD supports any of the following functions, they must be // queryable with vk_icdGetInstanceProcAddr: // vk_icdNegotiateLoaderICDInterfaceVersion // vk_icdGetPhysicalDeviceProcAddr // vk_icdEnumerateAdapterPhysicalDevices (Windows only) // In addition, these functions no longer need to be exported directly. // This version allows drivers provided through the extension // VK_LUNARG_direct_driver_loading be able to support the entire // Driver-Loader interface. #define CURRENT_LOADER_ICD_INTERFACE_VERSION 7 #define MIN_SUPPORTED_LOADER_ICD_INTERFACE_VERSION 0 #define MIN_PHYS_DEV_EXTENSION_ICD_INTERFACE_VERSION 4 // Old typedefs that don't follow a proper naming convention but are preserved for compatibility typedef VkResult(VKAPI_PTR *PFN_vkNegotiateLoaderICDInterfaceVersion)(uint32_t *pVersion);
