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
