我在尝试让 debugPrintfEXT 在着色器中工作时遇到问题

问题描述

似乎我部分工作了，但每次尝试登录时我都会收到此消息：

验证层：验证警告：[ UNASSIGNED-DEBUG-PRINTF ] 对象 0：句柄 = 0x19d6337ae88，类型 = VK_OBJECT_TYPE_DEVICE； |消息 ID = 0x92394c89 |警告 - 调试 Printf 消息被截断，可能是由于缓冲区大小对于消息来说太小

我现在只做一个字符测试日志，直到我让它工作，所以它不应该是一个问题。我也有 #extension GL_EXT_debug_printf ：在着色器中启用。

我已将调试器设置设为：

VkDebugUtilsMessengerCreateInfoEXT DebugInfo = {};
DebugInfo.sType = VK_STRUCTURE_TYPE_DEBUG_UTILS_MESSENGER_CREATE_INFO_EXT;
DebugInfo.messageSeverity = VK_DEBUG_UTILS_MESSAGE_SEVERITY_VERBOSE_BIT_EXT | VK_DEBUG_UTILS_MESSAGE_SEVERITY_WARNING_BIT_EXT | VK_DEBUG_UTILS_MESSAGE_SEVERITY_ERROR_BIT_EXT;|
DebugInfo.messageType = VK_DEBUG_UTILS_MESSAGE_TYPE_GENERAL_BIT_EXT | VK_DEBUG_UTILS_MESSAGE_TYPE_VALIDATION_BIT_EXT | VK_DEBUG_UTILS_MESSAGE_TYPE_PERFORMANCE_BIT_EXT;|
DebugInfo.pfnUserCallback = DebugCallBack;

启动验证信息：

    DeviceExtensions.emplace_back(VK_KHR_SHADER_NON_SEMANTIC_INFO_EXTENSION_NAME);

    VkValidationFeatureEnableEXT enabled[] = { VK_VALIDATION_FEATURE_ENABLE_DEBUG_PRINTF_EXT };
    VkValidationFeaturedisableEXT disabled[] = {
    VK_VALIDATION_FEATURE_disABLE_THREAD_SAFETY_EXT,VK_VALIDATION_FEATURE_disABLE_API_ParaMETERS_EXT,VK_VALIDATION_FEATURE_disABLE_OBJECT_LIFETIMES_EXT,VK_VALIDATION_FEATURE_disABLE_CORE_CHECKS_EXT };
    std::vector<const char*> ExtensionList = getrequiredExtensions();
    VkInstanceCreateInfo VulkanCreateInfo = {};
    VulkanCreateInfo.sType = VK_STRUCTURE_TYPE_INSTANCE_CREATE_INFO;
    VulkanCreateInfo.pApplicationInfo = &VulkanInfo;
    VulkanCreateInfo.enabledExtensionCount = static_cast<uint32_t>(ExtensionList.size());
    VulkanCreateInfo.ppEnabledExtensionNames = ExtensionList.data();

#ifdef NDEBUG
    VulkanCreateInfo.enabledLayerCount = 0;
    VulkanCreateInfo.pNext = nullptr;
#else
    VkDebugUtilsMessengerCreateInfoEXT DebugInfo;
    VulkanDebug.CreateDebugMessengerInfo(DebugInfo);

    VkValidationFeaturesEXT ValidationFeatures{};
    ValidationFeatures.sType = VK_STRUCTURE_TYPE_VALIDATION_FEATURES_EXT;
    ValidationFeatures.disabledValidationFeatureCount = 4;
    ValidationFeatures.enabledValidationFeatureCount = 1;
    ValidationFeatures.pEnabledValidationFeatures = enabled;
    ValidationFeatures.pdisabledValidationFeatures = disabled;
    ValidationFeatures.pNext = (VkDebugUtilsMessengerCreateInfoEXT*)&DebugInfo;

    VulkanCreateInfo.enabledLayerCount = static_cast<unsigned int>(ValidationLayers.size());
    VulkanCreateInfo.ppEnabledLayerNames = ValidationLayers.data();
    VulkanCreateInfo.pNext = &ValidationFeatures;

vk_layer_settings：

khronos_validation.debug_action = VK_DBG_LAYER_ACTION_LOG_MSG
khronos_validation.report_flags = error,warn,perf
khronos_validation.log_filename = stdout
khronos_validation.printf_buffer_size = 1024
khronos_validation.printf_verbose = true

这是我试图从中记录和调试的计算着色器。它应该可以做骨骼动画，但它遇到了一些问题，这让我找到了着色器记录器。

layout(push_constant) uniform MeshInfo

    uint MeshID;
    uint ModelID;
    uint MaterialID;

void main()
{

    debugPrintfEXT("H");
  Vertex v0 = vertices.v[gl_GlobalInvocationID.x];

  mat4 BoneTransform = mat4(1.0f);
  BoneTransform =  ubo.BoneTransform[v0.BoneID[0]] * v0.BoneWeights[0];
  BoneTransform += ubo.BoneTransform[v0.BoneID[1]] * v0.BoneWeights[1];
  BoneTransform += ubo.BoneTransform[v0.BoneID[2]] * v0.BoneWeights[2];
  BoneTransform += ubo.BoneTransform[v0.BoneID[3]] * v0.BoneWeights[3];
  vec4 BonePosition = BoneTransform * vec4(v0.Position,1.0);

  v0.Position = vec3(ubo.model * MeshTransform[0].Transform * BonePosition);
  v0.normal = normalize(transpose(inverse(mat3(ubo.model * MeshTransform[0].Transform * BoneTransform))) * v0.normal);
    v0.Color = vec4(v0.BoneID.xyz,1.0f);
  vertices.v[gl_GlobalInvocationID.x] = v0;
}

是不是我遗漏了什么？

还制作了一个简单的骨骼样本，但仍然收到相同的消息：

好的，我使用 vulkantutorial 使用了一个基本的 vulkan 模板并输入了着色器 printf 设置，但仍然出现相同的错误。

解决方法

您对每个计算着色器调用都进行了高度详细的打印。对于默认缓冲区大小 1024，这很可能是大量文本。因此，您需要降低着色器中的 printf 调用，并且还希望将消息的详细程度降低到例如只有 VK_DEBUG_UTILS_MESSAGE_SEVERITY_INFO_BIT_EXT 而不是 VK_DEBUG_UTILS_MESSAGE_SEVERITY_VERBOSE_BIT_EXT。
