Vulkan 验证警告 catch-22 关于 MoltenVK 上的 VK_KHR_portability_subset [英] Vulkan validation warning catch-22 about VK_KHR_portability_subset on MoltenVK

问题描述

我在 Big Sur(2014 年中 15 英寸视网膜)上使用 Vulkan 1.2.170 和 MoltenVK(和 GLFW).我用 VK_LAYER_KHRONOS_validation 创建了实例，当我调用 vkCreateDevice 时，我收到警告

I'm using Vulkan 1.2.170 with MoltenVK (and GLFW) on Big Sur (mid 2014 15" Retina). I created the instance with VK_LAYER_KHRONOS_validation and when I call vkCreateDevice I get the warning

VUID-VkDeviceCreateInfo-pProperties-04451(ERROR / SPEC): msgNum: 976972960 - Validation Error:
 [ VUID-VkDeviceCreateInfo-pProperties-04451 ] Object 0: handle = 0x10cfaad00, 
type = VK_OBJECT_TYPE_PHYSICAL_DEVICE; | MessageID = 0x3a3b6ca0 | vkCreateDevice: 
VK_KHR_portability_subset must be enabled because physical device VkPhysicalDevice 0x10cfaad00[] 
supports it The Vulkan spec states: If the [VK_KHR_portability_subset] extension is included in 
pProperties of vkEnumerateDeviceExtensionProperties, ppEnabledExtensions must include 
"VK_KHR_portability_subset".

好的，好的，我将它添加到 extensions 参数中作为唯一的扩展.然后它说

Okay, fine, I add it to the extensions parameter as the only extension. Then it says

Missing extension required by the device extension VK_KHR_portability_subset:
VK_KHR_get_physical_device_properties2.

和段错误.如果我添加 VK_KHR_get_physical_device_properties2，它会崩溃说它不存在，这是真的(vkEnumerateDeviceExtensionProperties 不返回它).

and segfaults. If I add VK_KHR_get_physical_device_properties2, it crashes saying it doesn't exist, which is true (vkEnumerateDeviceExtensionProperties doesn't return it).

这是一个错误还是它会接受一些扩展?

Is this a bug or is there some set of extensions it will accept?

如果有帮助，支持的扩展是

If it helps, the supported extensions are

推荐答案

原来 VK_KHR_get_physical_device_properties2 是一个实例扩展，而不是一个设备扩展，所以它传递给 vkCreateInstance 就像所以:

Turns out VK_KHR_get_physical_device_properties2 is an instance extension, not a device extension, so it's passed to vkCreateInstance like so:

VkInstanceCreateInfo instCreateInfo;
const char* instExtension = "VK_KHR_get_physical_device_properties2";
instCreateInfo.enabledExtensionCount = 1;
instCreateInfo.ppEnabledExtensionNames = &instExtension;
// etcetera
VkInstance instance;
vkCreateInstance(&instCreateInfo, nullptr, &instance);

// ...

VkDeviceCreateInfo deviceCreateInfo;
const char* deviceExtension = "VK_KHR_portability_subset";
deviceCreateInfo.enabledExtensionCount = 1;
deviceCreateInfo.ppEnabledExtensionNames = &deviceExtension;
// etcetera
VkDevice device;
vkCreateDevice(physicalDevice, &deviceCreateInfo, nullptr, &device);
