## 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 VK_KHR_descriptor_update_template is supported:

- vkCmdPushDescriptorSetWithTemplateKHR

If Version 1.1 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 VK_KHR_descriptor_update_template is supported:

- Extending VkDescriptorUpdateTemplateType:

  - `VK_DESCRIPTOR_UPDATE_TEMPLATE_TYPE_PUSH_DESCRIPTORS_KHR`

If Version 1.1 is supported:

- Extending VkDescriptorUpdateTemplateType:

  - `VK_DESCRIPTOR_UPDATE_TEMPLATE_TYPE_PUSH_DESCRIPTORS_KHR`

## Version History
