3785 * - Loader interface v0 is incompatible with later versions. We don't
3788 * - In loader interface v1:
3789 * - The first ICD entrypoint called by the loader is
3790 * vk_icdGetInstanceProcAddr(). The ICD must statically expose this
3792 * - The ICD must statically expose no other Vulkan symbol unless it is
3793 * linked with -Bsymbolic.
3794 * - Each dispatchable Vulkan handle created by the ICD must be
3795 * a pointer to a struct whose first member is VK_LOADER_DATA. The
3796 * ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
3797 * - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
3798 * vkDestroySurfaceKHR(). The ICD must be capable of working with
3799 * such loader-managed surfaces.
3801 * - Loader interface v2 differs from v1 in:
3802 * - The first ICD entrypoint called by the loader is
3803 * vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
3804 * statically expose this entrypoint.
3806 * - Loader interface v3 differs from v2 in:
3807 * - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
3808 * vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
3809 * because the loader no longer does so.
