Vulkan 验证失败提升了设备扩展依赖性

Question

vkCreateDevice 验证失败，因为包含的扩展的依赖项未包含在内。但是，此依赖项已升级到 Vulkan 1.1，这就是我正在使用的版本。如果我尝试包含依赖项，系统会抱怨扩展不可用，这是没有意义的。我想了解这种失败是否合理。

我正在尝试包括外部存储器 Android 硬件缓冲区扩展：https://www.khronos.org/registry/vulkan/specs/1.1-extensions/html/vkspec.html#VK_ANDROID_external_memory_android_hardware_buffer。我在设备扩展名称中包含以下元素：

VK_ANDROID_EXTERNAL_MEMORY_ANDROID_HARDWARE_BUFFER_EXTENSION_NAME
VK_KHR_SAMPLER_YCBCR_CONVERSION_EXTENSION_NAME
VK_EXT_QUEUE_FAMILY_FOREIGN_EXTENSION_NAME

我从验证中得到以下错误：

ERROR: (INSTANCE 0x0) [Validation]  [ VUID-vkCreateDevice-ppEnabledExtensionNames-01387 ] Object: VK_NULL_HANDLE (Type = 1) | Missing extension required by the device extension VK_ANDROID_external_memory_android_hardware_buffer: VK_KHR_external_memory. The Vulkan spec states: All required extensions for each extension in the VkDeviceCreateInfo::ppEnabledExtensionNames list must also be present in that list. (https://www.khronos.org/registry/vulkan/specs/1.1-extensions/html/vkspec.html#VUID-vkCreateDevice-ppEnabledExtensionNames-01387)

VK_KHR_external_memory 已升级为 1.1，当我查询 vkEnumerateInstanceVersion 时，我得到的是 1.1 版本。如果我添加 VK_KHR_external_memory 它会依次请求 VK_KHR_external_memory_capabilities，当我添加 VK_KHR_external_memory_capabilities 时系统会抱怨扩展不可用，尽管它也已升级到 1.1 .

Answer 1

我错误地将 VK_KHR_external_memory_capabilities 添加为设备扩展，而实际上它是一个实例扩展，即使它是设备扩展的依赖项。正确添加所有依赖项后，我没有任何失败或验证错误。

此外，我没有正确请求 1.1 API 版本。一旦我这样做了，我就不再需要明确指定 1.1 升级的扩展。
