Releases · GPUOpen-LibrariesAndSDKs/VulkanMemoryAllocator

A major release with many compatibility-breaking changes.

Notable new features:

Introduction of VmaAllocation handle that you must retrieve from allocation functions and pass to deallocation functions next to normal VkBuffer and VkImage.
Introduction of VmaAllocationInfo structure that you can retrieve from VmaAllocation handle to access parameters of the allocation (like VkDeviceMemory and offset) instead of retrieving them directly from allocation functions.
Support for reference-counted mapping and persistently mapped allocations - see vmaMapMemory, VMA_ALLOCATION_CREATE_MAPPED_BIT.
Support for custom memory pools - see VmaPool handle, VmaPoolCreateInfo structure, vmaCreatePool function.
Support for defragmentation (compaction) of allocations - see function vmaDefragment and related structures.
Support for "lost allocations" - see appropriate chapter on documentation Main Page.
