vulkan - 如何启用 VK_KHR_maintenance2 vulkan

问题描述

我正在尝试创建VkImageView将绑定到索引 0 的内容。

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!");
}

}

当我打电话时，vkUpdateDescriptorSets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viewInfo.pNext=nullptr;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

有人可以帮助我提示我如何解决该错误吗？

解决方案

错误消息会告诉您确切的操作。如果您使用VkImageViewUsageCreateInfo，这意味着您必须启用 maintenance2 扩展，或者依次启用它所升级到的 Vulkan 1.1。

由于您似乎对扩展的存在感到惊讶，因此您对它们的使用很可能只是偶然的。您可能只是想停止使用VkImageViewUsageCreateInfo扩展结构并始终设置pNext为NULL.
