## Description

This extension allows applications to insert markers in the command stream and associate them with custom data.

If a device lost error occurs, the application may then query the implementation for the last markers to cross specific implementation-defined pipeline stages, in order to narrow down which commands were executing at the time and might have caused the failure.

## New Commands

- vkCmdSetCheckpointNV

- vkGetQueueCheckpointDataNV

If Vulkan Version 1.3 or VK_KHR_synchronization2 is supported:

- vkGetQueueCheckpointData2NV

## New Structures

- VkCheckpointDataNV

- Extending VkQueueFamilyProperties2:

  - VkQueueFamilyCheckpointPropertiesNV

If Vulkan Version 1.3 or VK_KHR_synchronization2 is supported:

- VkCheckpointData2NV

- Extending VkQueueFamilyProperties2:

  - VkQueueFamilyCheckpointProperties2NV

## New Enum Constants

- `VK_NV_DEVICE_DIAGNOSTIC_CHECKPOINTS_EXTENSION_NAME`

- `VK_NV_DEVICE_DIAGNOSTIC_CHECKPOINTS_SPEC_VERSION`

- Extending VkStructureType:

  - VK_STRUCTURE_TYPE_CHECKPOINT_DATA_NV

  - VK_STRUCTURE_TYPE_QUEUE_FAMILY_CHECKPOINT_PROPERTIES_NV

If Vulkan Version 1.3 or VK_KHR_synchronization2 is supported:

- Extending VkStructureType:

  - VK_STRUCTURE_TYPE_CHECKPOINT_DATA_2_NV

  - VK_STRUCTURE_TYPE_QUEUE_FAMILY_CHECKPOINT_PROPERTIES_2_NV
