2427 * What follows is a condensed summary, to help you navigate the large and
2428 * confusing official doc.
2430 * - Loader interface v0 is incompatible with later versions. We don't
2433 * - In loader interface v1:
2434 * - The first ICD entrypoint called by the loader is
2435 * vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2437 * - The ICD must statically expose no other Vulkan symbol unless it is
2438 * linked with -Bsymbolic.
2439 * - Each dispatchable Vulkan handle created by the ICD must be
2440 * a pointer to a struct whose first member is VK_LOADER_DATA. The
2441 * ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
2442 * - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2443 * vkDestroySurfaceKHR(). The ICD must be capable of working with
2444 * such loader-managed surfaces.
2446 * - Loader interface v2 differs from v1 in:
2447 * - The first ICD entrypoint called by the loader is
2448 * vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2449 * statically expose this entrypoint.
2451 * - Loader interface v3 differs from v2 in:
2452 * - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2453 * vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2454 * because the loader no longer does so.
