Description

Due to the nature of the Vulkan interface, there is very little error information available to the developer and application. By using the VK_EXT_debug_utils extension, developers can obtain more information. When combined with validation layers, even more detailed feedback on the application’s use of Vulkan will be provided.

This extension provides the following capabilities:

• The ability to create a debug messenger which will pass along debug messages to an application supplied callback.
• The ability to identify specific Vulkan objects using a name or tag to improve tracking.
• The ability to identify specific sections within a Queue or CommandBuffer using labels to aid organization and offline analysis in external tools.

The main difference between this extension and VK_EXT_debug_report and VK_EXT_debug_marker is that those extensions use DebugReportObjectTypeEXT to identify objects. This extension uses the core ObjectType in place of DebugReportObjectTypeEXT. The primary reason for this move is that no future object type handle enumeration values will be added to DebugReportObjectTypeEXT since the creation of ObjectType.

In addition, this extension combines the functionality of both VK_EXT_debug_report and VK_EXT_debug_marker by allowing object name and debug markers (now called labels) to be returned to the application’s callback function. This should assist in clarifying the details of a debug message including: what objects are involved and potentially which location within a Queue or CommandBuffer the message occurred.

Examples

Example 1

VK_EXT_debug_utils allows an application to register multiple callbacks with any Vulkan component wishing to report debug information. Some callbacks may log the information to a file, others may cause a debug break point or other application defined behavior. An application can register callbacks even when no validation layers are enabled, but they will only be called for loader and, if implemented, driver events.

To capture events that occur while creating or destroying an instance an application can link a DebugUtilsMessengerCreateInfoEXT structure to the pNext element of the InstanceCreateInfo structure given to createInstance.

Example uses: Create three callback objects. One will log errors and warnings to the debug console using Windows OutputDebugString. The second will cause the debugger to break at that callback when an error happens and the third will log warnings to stdout.

    extern VkInstance instance;
    VkResult res;
    VkDebugUtilsMessengerEXT cb1, cb2, cb3;

    // Must call extension functions through a function pointer:
    PFN_vkCreateDebugUtilsMessengerEXT pfnCreateDebugUtilsMessengerEXT = (PFN_vkCreateDebugUtilsMessengerEXT)vkGetInstanceProcAddr(instance, "vkCreateDebugUtilsMessengerEXT");
    PFN_vkDestroyDebugUtilsMessengerEXT pfnDestroyDebugUtilsMessengerEXT = (PFN_vkDestroyDebugUtilsMessengerEXT)vkGetInstanceProcAddr(instance, "vkDestroyDebugUtilsMessengerEXT");

    VkDebugUtilsMessengerCreateInfoEXT callback1 = {
            VK_STRUCTURE_TYPE_DEBUG_UTILS_MESSENGER_CREATE_INFO_EXT,  // sType
            NULL,                                                     // pNext
            0,                                                        // flags

            VK_DEBUG_UTILS_MESSAGE_TYPE_VALIDATION_BIT_EXT,
            myOutputDebugString,                                      // pfnUserCallback
            NULL                                                      // pUserData
    };
    res = pfnCreateDebugUtilsMessengerEXT(instance, &callback1, NULL, &cb1);
    if (res != VK_SUCCESS) {
       // Do error handling for VK_ERROR_OUT_OF_MEMORY
    }

    callback1.messageSeverity = VK_DEBUG_UTILS_MESSAGE_SEVERITY_ERROR_BIT_EXT;
    callback1.pfnUserCallback = myDebugBreak;
    callback1.pUserData = NULL;
    res = pfnCreateDebugUtilsMessengerEXT(instance, &callback1, NULL, &cb2);
    if (res != VK_SUCCESS) {
       // Do error handling for VK_ERROR_OUT_OF_MEMORY
    }

    VkDebugUtilsMessengerCreateInfoEXT callback3 = {
            VK_STRUCTURE_TYPE_DEBUG_UTILS_MESSENGER_CREATE_INFO_EXT,  // sType
            NULL,                                                     // pNext
            0,                                                        // flags
            VK_DEBUG_UTILS_MESSAGE_SEVERITY_WARNING_BIT_EXT,          // messageSeverity
            VK_DEBUG_UTILS_MESSAGE_TYPE_GENERAL_BIT_EXT |             // messageType
            VK_DEBUG_UTILS_MESSAGE_TYPE_VALIDATION_BIT_EXT,
            mystdOutLogger,                                           // pfnUserCallback
            NULL                                                      // pUserData
    };
    res = pfnCreateDebugUtilsMessengerEXT(instance, &callback3, NULL, &cb3);
    if (res != VK_SUCCESS) {
       // Do error handling for VK_ERROR_OUT_OF_MEMORY
    }

    ...

    // Remove callbacks when cleaning up
    pfnDestroyDebugUtilsMessengerEXT(instance, cb1, NULL);
    pfnDestroyDebugUtilsMessengerEXT(instance, cb2, NULL);

Example 2

Associate a name with an image, for easier debugging in external tools or with validation layers that can print a friendly name when referring to objects in error messages.

    extern VkInstance instance;
    extern VkDevice device;
    extern VkImage image;

    // Must call extension functions through a function pointer:
    PFN_vkSetDebugUtilsObjectNameEXT pfnSetDebugUtilsObjectNameEXT = (PFN_vkSetDebugUtilsObjectNameEXT)vkGetInstanceProcAddr(instance, "vkSetDebugUtilsObjectNameEXT");

    // Set a name on the image
    const VkDebugUtilsObjectNameInfoEXT imageNameInfo =
    {
        VK_STRUCTURE_TYPE_DEBUG_UTILS_OBJECT_NAME_INFO_EXT, // sType
        NULL,                                               // pNext
        VK_OBJECT_TYPE_IMAGE,                               // objectType
        (uint64_t)image,                                    // objectHandle
        "Brick Diffuse Texture",                            // pObjectName
    };

    pfnSetDebugUtilsObjectNameEXT(device, &imageNameInfo);

    // A subsequent error might print:
    //   Image 'Brick Diffuse Texture' (0xc0dec0dedeadbeef) is used in a
    //   command buffer with no memory bound to it.

Issues

1) Should we just name this extension VK_EXT_debug_report2

RESOLVED: No. There is enough additional changes to the structures to break backwards compatibility. So, a new name was decided that would not indicate any interaction with the previous extension.

2) Will validation layers immediately support all the new features.

RESOLVED: Not immediately. As one can imagine, there is a lot of work involved with converting the validation layer logging over to the new functionality. Basic logging, as seen in the origin VK_EXT_debug_report extension will be made available immediately. However, adding the labels and object names will take time. Since the priority for Khronos at this time is to continue focusing on Valid Usage statements, it may take a while before the new functionality is fully exposed.

3) If the validation layers will not expose the new functionality immediately, then what is the point of this extension?

RESOLVED: We needed a replacement for VK_EXT_debug_report because the DebugReportObjectTypeEXT enumeration will no longer be updated and any new objects will need to be debugged using the new functionality provided by this extension.

4) Should this extension be split into two separate parts (1 extension that is an instance extension providing the callback functionality, and another device extension providing the general debug marker and annotation functionality)?

RESOLVED: No, the functionality for this extension is too closely related. If we did split up the extension, where would the structures and enums live, and how would you define that the device behavior in the instance extension is really only valid if the device extension is enabled, and the functionality is passed in. It is cleaner to just define this all as an instance extension, plus it allows the application to enable all debug functionality provided with one enable string during createInstance.

Version History

• Revision 1, 2017-09-14 (Mark Young and all listed Contributors)

  • Initial draft, based on VK_EXT_debug_report and VK_EXT_debug_marker in addition to previous feedback supplied from various companies including Valve, Epic, and Oxide games.

• Revision 2, 2020-04-03 (Mark Young and Piers Daniell)

  • Updated to allow either NULL or an empty string to be passed in for pObjectName in DebugUtilsObjectNameInfoEXT, because the loader and various drivers support NULL already.

cmdEndDebugUtilsLabelEXT

Arguments

:: forall io. MonadIO io

=> CommandBuffer

commandBuffer is the command buffer into which the command is recorded.

-> io ()

vkCmdEndDebugUtilsLabelEXT - Close a command buffer label region

Description

An application may open a debug label region in one command buffer and close it in another, or otherwise split debug label regions across multiple command buffers or multiple queue submissions. When viewed from the linear series of submissions to a single queue, the calls to cmdBeginDebugUtilsLabelEXT and cmdEndDebugUtilsLabelEXT must be matched and balanced.

There can be problems reporting command buffer debug labels during the recording process because command buffers may be recorded out of sequence with the resulting execution order. Since the recording order may be different, a solitary command buffer may have an inconsistent view of the debug label regions by itself. Therefore, if an issue occurs during the recording of a command buffer, and the environment requires returning debug labels, the implementation may return only those labels it is aware of. This is true even if the implementation is aware of only the debug labels within the command buffer being actively recorded.

Valid Usage

• There must be an outstanding cmdBeginDebugUtilsLabelEXT command prior to the cmdEndDebugUtilsLabelEXT on the queue that commandBuffer is submitted to

• If commandBuffer is a secondary command buffer, there must be an outstanding cmdBeginDebugUtilsLabelEXT command recorded to commandBuffer that has not previously been ended by a call to cmdEndDebugUtilsLabelEXT

Valid Usage (Implicit)

• commandBuffer must be a valid CommandBuffer handle

• commandBuffer must be in the recording state
• The CommandPool that commandBuffer was allocated from must support graphics, or compute operations
• This command must only be called outside of a video coding scope

Host Synchronization

• Host access to commandBuffer must be externally synchronized

• Host access to the CommandPool that commandBuffer was allocated from must be externally synchronized

withDebugUtilsMessengerEXT :: forall io r. MonadIO io => Instance -> DebugUtilsMessengerCreateInfoEXT -> Maybe AllocationCallbacks -> (io DebugUtilsMessengerEXT -> (DebugUtilsMessengerEXT -> io ()) -> r) -> r

A convenience wrapper to make a compatible pair of calls to createDebugUtilsMessengerEXT and destroyDebugUtilsMessengerEXT

To ensure that destroyDebugUtilsMessengerEXT is always called: pass bracket (or the allocate function from your favourite resource management library) as the last argument. To just extract the pair pass (,) as the last argument.

destroyDebugUtilsMessengerEXT

Arguments

:: forall io. MonadIO io

=> Instance

instance is the instance where the callback was created.

-> DebugUtilsMessengerEXT

messenger is the DebugUtilsMessengerEXT object to destroy. messenger is an externally synchronized object and must not be used on more than one thread at a time. This means that destroyDebugUtilsMessengerEXT must not be called when a callback is active.

-> ("allocator" ::: Maybe AllocationCallbacks)

pAllocator controls host memory allocation as described in the Memory Allocation chapter.

-> io ()

vkDestroyDebugUtilsMessengerEXT - Destroy a debug messenger object

Valid Usage

• If AllocationCallbacks were provided when messenger was created, a compatible set of callbacks must be provided here

• If no AllocationCallbacks were provided when messenger was created, pAllocator must be NULL

Valid Usage (Implicit)

• instance must be a valid Instance handle

• If messenger is not NULL_HANDLE, messenger must be a valid DebugUtilsMessengerEXT handle
• If pAllocator is not NULL, pAllocator must be a valid pointer to a valid AllocationCallbacks structure
• If messenger is a valid handle, it must have been created, allocated, or retrieved from instance

Host Synchronization

• Host access to messenger must be externally synchronized

The application must ensure that destroyDebugUtilsMessengerEXT is not executed in parallel with any Vulkan command that is also called with instance or child of instance as the dispatchable argument.

data DebugUtilsObjectNameInfoEXT

VkDebugUtilsObjectNameInfoEXT - Specify parameters of a name to give to an object

Description

Applications may change the name associated with an object simply by calling setDebugUtilsObjectNameEXT again with a new string. If pObjectName is either NULL or an empty string, then any previously set name is removed.

The graphicsPipelineLibrary feature allows the specification of pipelines without the creation of ShaderModule objects beforehand. In order to continue to allow naming these shaders independently, DebugUtilsObjectNameInfoEXT can be included in the pNext chain of PipelineShaderStageCreateInfo, which associates a static name with that particular shader.

Valid Usage

• If objectType is OBJECT_TYPE_UNKNOWN, objectHandle must not be NULL_HANDLE

• If objectType is not OBJECT_TYPE_UNKNOWN, objectHandle must be NULL_HANDLE or a valid Vulkan handle of the type associated with objectType as defined in the and Vulkan Handle Relationship table

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_DEBUG_UTILS_OBJECT_NAME_INFO_EXT

• objectType must be a valid ObjectType value
• If pObjectName is not NULL, pObjectName must be a null-terminated UTF-8 string

data DebugUtilsMessengerCreateInfoEXT

VkDebugUtilsMessengerCreateInfoEXT - Structure specifying parameters of a newly created debug messenger

Description

For each DebugUtilsMessengerEXT that is created the DebugUtilsMessengerCreateInfoEXT::messageSeverity and DebugUtilsMessengerCreateInfoEXT::messageType determine when that DebugUtilsMessengerCreateInfoEXT::pfnUserCallback is called. The process to determine if the user’s pfnUserCallback is triggered when an event occurs is as follows:

1. The implementation will perform a bitwise AND of the event’s DebugUtilsMessageSeverityFlagBitsEXT with the messageSeverity provided during creation of the DebugUtilsMessengerEXT object.

   1. If the value is 0, the message is skipped.

2. The implementation will perform bitwise AND of the event’s DebugUtilsMessageTypeFlagBitsEXT with the messageType provided during the creation of the DebugUtilsMessengerEXT object.

   1. If the value is 0, the message is skipped.
3. The callback will trigger a debug message for the current event

The callback will come directly from the component that detected the event, unless some other layer intercepts the calls for its own purposes (filter them in a different way, log to a system error log, etc.).

An application can receive multiple callbacks if multiple DebugUtilsMessengerEXT objects are created. A callback will always be executed in the same thread as the originating Vulkan call.

A callback can be called from multiple threads simultaneously (if the application is making Vulkan calls from multiple threads).

data DebugUtilsMessengerCallbackDataEXT

VkDebugUtilsMessengerCallbackDataEXT - Structure specifying parameters returned to the callback

Description

Note

This structure should only be considered valid during the lifetime of the triggered callback.

Since adding queue and command buffer labels behaves like pushing and popping onto a stack, the order of both pQueueLabels and pCmdBufLabels is based on the order the labels were defined. The result is that the first label in either pQueueLabels or pCmdBufLabels will be the first defined (and therefore the oldest) while the last label in each list will be the most recent.

Note

pQueueLabels will only be non-NULL if one of the objects in pObjects can be related directly to a defined Queue which has had one or more labels associated with it.

Likewise, pCmdBufLabels will only be non-NULL if one of the objects in pObjects can be related directly to a defined CommandBuffer which has had one or more labels associated with it. Additionally, while command buffer labels allow for beginning and ending across different command buffers, the debug messaging framework cannot guarantee that labels in pCmdBufLables will contain those defined outside of the associated command buffer. This is partially due to the fact that the association of one command buffer with another may not have been defined at the time the debug message is triggered.

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_DEBUG_UTILS_MESSENGER_CALLBACK_DATA_EXT

• pNext must be NULL
• flags must be 0
• If pMessageIdName is not NULL, pMessageIdName must be a null-terminated UTF-8 string
• pMessage must be a null-terminated UTF-8 string
• If queueLabelCount is not 0, pQueueLabels must be a valid pointer to an array of queueLabelCount valid DebugUtilsLabelEXT structures
• If cmdBufLabelCount is not 0, pCmdBufLabels must be a valid pointer to an array of cmdBufLabelCount valid DebugUtilsLabelEXT structures
• If objectCount is not 0, pObjects must be a valid pointer to an array of objectCount valid DebugUtilsObjectNameInfoEXT structures

• messageIdNumber :: Int32

  messageIdNumber is the ID number of the triggering message. If the message corresponds to a validation layer message, then this number is related to the internal number associated with the message being triggered.

• message :: ByteString

  pMessage is a null-terminated string detailing the trigger conditions.

• queueLabels :: Vector DebugUtilsLabelEXT

  pQueueLabels is NULL or a pointer to an array of DebugUtilsLabelEXT active in the current Queue at the time the callback was triggered. Refer to Queue Labels for more information.

• cmdBufLabels :: Vector DebugUtilsLabelEXT

  pCmdBufLabels is NULL or a pointer to an array of DebugUtilsLabelEXT active in the current CommandBuffer at the time the callback was triggered. Refer to Command Buffer Labels for more information.

• objects :: Vector DebugUtilsObjectNameInfoEXT

  pObjects is a pointer to an array of DebugUtilsObjectNameInfoEXT objects related to the detected issue. The array is roughly in order or importance, but the 0th element is always guaranteed to be the most important object for this message.

VkDebugUtilsMessageSeverityFlagBitsEXT - Bitmask specifying which severities of events cause a debug messenger callback

Description

Note

The values of DebugUtilsMessageSeverityFlagBitsEXT are sorted based on severity. The higher the flag value, the more severe the message. This allows for simple boolean operation comparisons when looking at DebugUtilsMessageSeverityFlagBitsEXT values.

For example:

    if (messageSeverity >= VK_DEBUG_UTILS_MESSAGE_SEVERITY_WARNING_BIT_EXT) {
        // Do something for warnings and errors
    }

In addition, space has been left between the enums to allow for later addition of new severities in between the existing values.

pattern DEBUG_UTILS_MESSAGE_SEVERITY_WARNING_BIT_EXT :: DebugUtilsMessageSeverityFlagBitsEXT

DEBUG_UTILS_MESSAGE_SEVERITY_WARNING_BIT_EXT specifies use of Vulkan that may expose an app bug. Such cases may not be immediately harmful, such as a fragment shader outputting to a location with no attachment. Other cases may point to behavior that is almost certainly bad when unintended such as using an image whose memory has not been filled. In general if you see a warning but you know that the behavior is intended/desired, then simply ignore the warning.

pattern DEBUG_UTILS_MESSAGE_SEVERITY_ERROR_BIT_EXT :: DebugUtilsMessageSeverityFlagBitsEXT

DEBUG_UTILS_MESSAGE_SEVERITY_ERROR_BIT_EXT specifies that the application has violated a valid usage condition of the specification.

Bundled Patterns

pattern DEBUG_UTILS_MESSAGE_TYPE_GENERAL_BIT_EXT :: DebugUtilsMessageTypeFlagBitsEXT

DEBUG_UTILS_MESSAGE_TYPE_GENERAL_BIT_EXT specifies that some general event has occurred. This is typically a non-specification, non-performance event.

pattern DEBUG_UTILS_MESSAGE_TYPE_VALIDATION_BIT_EXT :: DebugUtilsMessageTypeFlagBitsEXT

DEBUG_UTILS_MESSAGE_TYPE_VALIDATION_BIT_EXT specifies that something has occurred during validation against the Vulkan specification that may indicate invalid behavior.

pattern DEBUG_UTILS_MESSAGE_TYPE_PERFORMANCE_BIT_EXT :: DebugUtilsMessageTypeFlagBitsEXT

DEBUG_UTILS_MESSAGE_TYPE_PERFORMANCE_BIT_EXT specifies a potentially non-optimal use of Vulkan, e.g. using cmdClearColorImage when setting AttachmentDescription::loadOp to ATTACHMENT_LOAD_OP_CLEAR would have worked.

type PFN_vkDebugUtilsMessengerCallbackEXT = FunPtr FN_vkDebugUtilsMessengerCallbackEXT

PFN_vkDebugUtilsMessengerCallbackEXT - Application-defined debug messenger callback function

Description

The callback returns a Bool32, which is interpreted in a layer-specified manner. The application should always return FALSE. The TRUE value is reserved for use in layer development.

Valid Usage

• The callback must not make calls to any Vulkan commands

newtype DebugUtilsMessengerEXT

VkDebugUtilsMessengerEXT - Opaque handle to a debug messenger object

Description

The debug messenger will provide detailed feedback on the application’s use of Vulkan when events of interest occur. When an event of interest does occur, the debug messenger will submit a debug message to the debug callback that was provided during its creation. Additionally, the debug messenger is responsible with filtering out debug messages that the callback is not interested in and will only provide desired debug messages.
