Description

This extension provides extensible versions of the Vulkan memory map and unmap commands. The new commands are functionally identical to the core commands, except that their parameters are specified using extensible structures that can be used to pass extension-specific information.

New Commands

• vkMapMemory2KHR
• vkUnmapMemory2KHR

New Structures

• VkMemoryMapInfoKHR
• VkMemoryUnmapInfoKHR

New Enums

• VkMemoryUnmapFlagBitsKHR

New Bitmasks

• VkMemoryUnmapFlagsKHR

New Enum Constants

• VK_KHR_MAP_MEMORY_2_EXTENSION_NAME
• VK_KHR_MAP_MEMORY_2_SPEC_VERSION
• Extending VkStructureType:
  • VK_STRUCTURE_TYPE_MEMORY_MAP_INFO_KHR
  • VK_STRUCTURE_TYPE_MEMORY_UNMAP_INFO_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.
