Vulkan 验证层抱怨未启用扩展，代码就像启用了扩展一样工作
Vulkan validation layers complain about extension not enabled, code works as if extension was enabled
我正在尝试使用动态呈现扩展，为此我正在以这种方式初始化我的实例：
auto enabled = vk::ValidationFeatureEnableEXT::eBestPractices;
vk::ValidationFeaturesEXT features;
features.enabledValidationFeatureCount = 1;
features.pEnabledValidationFeatures = &enabled;
vk::PhysicalDeviceDynamicRenderingFeaturesKHR dynamic_rendering = {};
dynamic_rendering.dynamicRendering = true;
features.pNext = &dynamic_rendering;
// Setup general information about the current application.
vk::ApplicationInfo program_info(
"NeverEngine",
VK_MAKE_VERSION(1, 0, 0),
"No Engine",
VK_MAKE_VERSION(1, 0, 0),
VK_API_VERSION_1_2);
// Create Vulkan instance to communicate with the loader.
vk::InstanceCreateInfo create_info = {};
create_info.pNext = &features;
create_info.pApplicationInfo = &program_info,
create_info.enabledLayerCount = static_cast<uint32_t>(VALIDATION_LAYERS.size()),
create_info.ppEnabledLayerNames = VALIDATION_LAYERS.data(),
create_info.enabledExtensionCount = static_cast<uint32_t>(required_extensions.size()),
create_info.ppEnabledExtensionNames = required_extensions.data();
auto [result, instance] = vk::createInstanceUnique(create_info);
Assert(result == vk::Result::eSuccess, "Error: Failed to create instance");
但是我收到了这些错误：
VUID-VkInstanceCreateInfo-pNext-pNext(ERROR / SPEC): msgNum: -1337267667 - Validation Error: [ VUID-VkInstanceCreateInfo-pNext-pNext ] Object 0: VK_NULL_HANDLE, type = VK_OBJECT_TYPE_DEVICE; | MessageID = 0xb04aea2d | vkCreateInstance: pCreateInfo->pNext chain includes a structure with unexpected VkStructureType VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_DYNAMIC_RENDERING_FEATURES; Allowed structures are [VkDebugReportCallbackCreateInfoEXT, VkDebugUtilsMessengerCreateInfoEXT, VkValidationFeaturesEXT, VkValidationFlagsEXT]. This error is based on the Valid Usage documentation for version 204 of the Vulkan header.

我的driver、headers和验证层都是最新版本1.3.204。
如果我不启用层，只启用 运行 我的代码，事情似乎工作正常，我可以调整我的 window 的大小并按预期更新渲染。这是验证层中的错误吗？
一些 research 建议我应该这样做：
const std::vector<const char*> device_extensions = {
VK_KHR_SWAPCHAIN_EXTENSION_NAME,
VK_KHR_DYNAMIC_RENDERING_EXTENSION_NAME,
VK_EXT_EXTENDED_DYNAMIC_STATE_EXTENSION_NAME,
};
vk::PhysicalDeviceDynamicRenderingFeaturesKHR dynamic_rendering = {};
dynamic_rendering.dynamicRendering = true;
// Get the features of the selected device.
vk::PhysicalDeviceFeatures device_features = phys_device.getFeatures();
// The enabledLayerCount and ppEnabledLayerNames parameters are deprecated,
// they should always be 0 and nullptr.
// https://www.khronos.org/registry/vulkan/specs/1.1-extensions/man/html/VkDeviceCreateInfo.html
vk::DeviceCreateInfo create_info = {};
create_info.pNext = &dynamic_rendering;
create_info.queueCreateInfoCount = queue_create_infos.size();
create_info.pQueueCreateInfos = queue_create_infos.data();
create_info.enabledLayerCount = 0;
create_info.ppEnabledLayerNames = nullptr;
create_info.enabledExtensionCount = device_extensions.size();
create_info.ppEnabledExtensionNames = device_extensions.data();
create_info.pEnabledFeatures = &device_features;
但这会返回以下错误：

我不明白，我正在启用扩展程序。
按照评论中的建议，我看到了这个：
vkCreateDevice(physicalDevice, pCreateInfo, pAllocator, pDevice) returns VkResult VK_SUCCESS (0):
physicalDevice: VkPhysicalDevice = 0x32f85c0
pCreateInfo: const VkDeviceCreateInfo* = 0x7fff0d9dbb20:
sType: VkStructureType = VK_STRUCTURE_TYPE_DEVICE_CREATE_INFO (3)
pNext: const void* = NULL
这似乎表明 pNext 设置不正确。
您可能需要将 VK_KHR_DYNAMIC_RENDERING_EXTENSION_NAME 添加到 device_extensions 列表中。您没有显示设置该列表的代码。其余的看起来还可以。
driver 继续使用请求的功能并不少见，即使它没有启用。但由于它可以从 driver 更改为 driver，因此最好始终启用您需要的扩展和功能。
