## Description

This extension allows list primitives to use the primitive restart index value. This provides a more efficient implementation when layering OpenGL functionality on Vulkan by avoiding emulation which incurs data copies.

## New Structures

- Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:

  - VkPhysicalDevicePrimitiveTopologyListRestartFeaturesEXT

## New Enum Constants

- `VK_EXT_PRIMITIVE_TOPOLOGY_LIST_RESTART_EXTENSION_NAME`

- `VK_EXT_PRIMITIVE_TOPOLOGY_LIST_RESTART_SPEC_VERSION`

- Extending VkStructureType:

  - `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PRIMITIVE_TOPOLOGY_LIST_RESTART_FEATURES_EXT`

## Version History
