0.1.3 (2018-12-17)

Updated to AMD VMA 2.2 release!

Notable new features: defragmentation of GPU memory, buddy algorithm, convenience functions for sparse binding.

Major changes:

  • New, more powerful defragmentation:
    • DefragmentationInfo2
    • Allocator::defragmentation_begin
    • Allocator::defragmentation_end
  • Added support for defragmentation of GPU memory.
  • Defragmentation of CPU memory now uses memmove internally, so it can move data to overlapping regions.
  • Defragmentation of CPU memory is now available for memory types that are ash::vk::MemoryPropertyFlags::HOST_VISIBLE but not ash::vk::MemoryPropertyFlags::HOST_COHERENT.
  • Major internal changes in defragmentation algorithm.
  • Old interface (structure DefragmentationInfo, function Allocator::defragment) is now deprecated.
  • Added buddy algorithm, available for custom pools:
    • AllocatorPoolCreateFlags::BUDDY_ALGORITHM
  • Added convenience functions for multiple allocations and deallocations at once, intended for sparse binding resources:
    • Allocator::allocate_memory_pages
    • Allocator::free_memory_pages
  • Added function that tries to resize existing allocation in place:
    • Allocator::resize_allocation
  • Added flags for allocation strategy
    • New flags:
      • AllocationCreateFlags::STRATEGY_BEST_FIT
      • AllocationCreateFlags::STRATEGY_WORST_FIT
      • AllocationCreateFlags::STRATEGY_FIRST_FIT
    • Their aliases:
      • AllocationCreateFlags::STRATEGY_MIN_MEMORY
      • AllocationCreateFlags::STRATEGY_MIN_TIME
      • AllocationCreateFlags::STRATEGY_MIN_FRAGMENTATION

Minor changes:

  • Changed behavior of allocation functions to return ash::vk::Result::ERROR_VALIDATION_FAILED_EXT when trying to allocate memory of size 0, create buffer with size 0, or image with one of the dimensions 0.
  • Internal optimization: using read-write mutex on some platforms.
  • Many additions and fixes in documentation. Many compatibility fixes for various compilers. Other internal bugfixes, optimizations, refactoring, added more internal validation...

0.1.2 (2018-12-11)

  • Minor documentation tweak.

0.1.1 (2018-12-11)

  • Major refactors.
  • Full documentation pass.

0.1.0 (2018-12-11)

  • First release.
