4131 * - Loader interface v0 is incompatible with later versions. We don't
4134 * - In loader interface v1:
4135 * - The first ICD entrypoint called by the loader is
4136 * vk_icdGetInstanceProcAddr(). The ICD must statically expose this
4138 * - The ICD must statically expose no other Vulkan symbol unless it is
4139 * linked with -Bsymbolic.
4140 * - Each dispatchable Vulkan handle created by the ICD must be
4141 * a pointer to a struct whose first member is VK_LOADER_DATA. The
4142 * ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
4143 * - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
4144 * vkDestroySurfaceKHR(). The ICD must be capable of working with
4145 * such loader-managed surfaces.
4147 * - Loader interface v2 differs from v1 in:
4148 * - The first ICD entrypoint called by the loader is
4149 * vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
4150 * statically expose this entrypoint.
4152 * - Loader interface v3 differs from v2 in:
4153 * - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
4154 * vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
4155 * because the loader no longer does so.
4157 * - Loader interface v4 differs from v3 in:
4158 * - The ICD must implement vk_icdGetPhysicalDeviceProcAddr().
