如何启用 VK_KHR_maintenance2 vulkan

问题描述

我正在尝试创建将绑定到索引 0 的 VkImageView。

这是我的 VkImageView 创建代码

void Image::createImageView() {
VkImageViewUsageCreateInfo imageViewUsage;
imageViewUsage.sType=VK_STRUCTURE_TYPE_IMAGE_VIEW_USAGE_CREATE_INFO;
imageViewUsage.pNext=nullptr;
imageViewUsage.usage=VK_IMAGE_USAGE_STORAGE_BIT;


VkImageViewCreateInfo viewInfo{};
viewInfo.sType = VK_STRUCTURE_TYPE_IMAGE_VIEW_CREATE_INFO;
viewInfo.pNext=&imageViewUsage;
viewInfo.image = textureImage;
viewInfo.viewType = VK_IMAGE_VIEW_TYPE_2D;
viewInfo.format = VK_FORMAT_R8G8B8A8_UnorM;
viewInfo.subresourceRange.aspectMask = VK_IMAGE_ASPECT_COLOR_BIT;
viewInfo.subresourceRange.baseMipLevel = 0;
viewInfo.subresourceRange.levelCount = 1;
viewInfo.subresourceRange.baseArrayLayer = 0;
viewInfo.subresourceRange.layerCount = 1;

if (vkCreateImageView(device,&viewInfo,nullptr,&textureImageView) != VK_SUCCESS) {
    throw std::runtime_error("Failed to create texture image view!");
}

}

当我调用 vkUpdateDescriptorSets 时，我收到验证错误：

vkCreateImageView: Includes a pNext pointer (pCreateInfo->pNext) to a VkStructureType (VK_STRUCTURE_TYPE_IMAGE_VIEW_USAGE_CREATE_INFO),but its parent extension VK_KHR_maintenance2 has not been enabled. The Vulkan spec states: Each pNext member of any structure (including this one) in the pNext chain must be either NULL or a pointer to a valid instance of VkImageViewASTCDecodemodeEXT,VkImageViewUsageCreateInfo,VkSamplerycbcrConversionInfo,VkVideoProfileKHR,or VkVideoProfilesKHR

在此之前，我已经设置了 viewInfo.pNext=nullptr;，但我收到了验证错误：

Write update to VkDescriptorSet 0xf018750000000004[] allocated with VkDescriptorSetLayout 0x683e70000000002[] binding #0 Failed with error message: Attempted write update to image descriptor Failed due to: ImageView (VkImageView 0xa3c6870000000008[]) with usage mask 0x6 being used for a descriptor update of type VK_DESCRIPTOR_TYPE_STORAGE_IMAGE does not have VK_IMAGE_USAGE_STORAGE_BIT set

有人可以帮我提供一些提示，我该如何解决错误？

解决方法

错误消息会准确地告诉您该怎么做。如果您使用 VkImageViewUsageCreateInfo，则意味着您必须启用维护 2 扩展或反过来将其升级到的 Vulkan 1.1。

因为您似乎对扩展的存在感到惊讶，所以您可能只是偶然使用它们。您可能只想停止使用 VkImageViewUsageCreateInfo 扩展结构并始终将 pNext 设置为 NULL。
