## Description

This extension allows descriptors to be written into the command buffer, while the implementation is responsible for managing their memory. Push descriptors may enable easier porting from older APIs and in some cases can be more efficient than writing descriptors into descriptor sets.

## New Commands

- vkCmdPushDescriptorSetKHR

If Vulkan Version 1.1 or VK_KHR_descriptor_update_template is supported:

- vkCmdPushDescriptorSetWithTemplateKHR

## New Structures

- Extending VkPhysicalDeviceProperties2:

  - VkPhysicalDevicePushDescriptorPropertiesKHR

## New Enum Constants

- `VK_KHR_PUSH_DESCRIPTOR_EXTENSION_NAME`

- `VK_KHR_PUSH_DESCRIPTOR_SPEC_VERSION`

- Extending VkDescriptorSetLayoutCreateFlagBits:

  - `VK_DESCRIPTOR_SET_LAYOUT_CREATE_PUSH_DESCRIPTOR_BIT_KHR`

- Extending VkStructureType:

  - `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PUSH_DESCRIPTOR_PROPERTIES_KHR`

If Vulkan Version 1.1 or VK_KHR_descriptor_update_template is supported:

- Extending VkDescriptorUpdateTemplateType:

  - `VK_DESCRIPTOR_UPDATE_TEMPLATE_TYPE_PUSH_DESCRIPTORS_KHR`

## Promotion to Vulkan 1.4

Functionality in this extension is included in core Vulkan 1.4 with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.
