    v2.2.0 Stable

    archiver-bot released this 2018-12-13 05:15:01 -06:00 | 943 commits to master since this release

    Major release after many months of development in "master" branch and feature branches. Notable new features: defragmentation of GPU memory, buddy algorithm, convenience functions for sparse binding.

    Major changes:

    • New, more powerful defragmentation:
      • Added structure VmaDefragmentationInfo2, functions vmaDefragmentationBegin, vmaDefragmentationEnd.
      • Added support for defragmentation of GPU memory.
      • Defragmentation of CPU memory now uses memmove, so it can move data to overlapping regions.
      • Defragmentation of CPU memory is now available for memory types that are HOST_VISIBLE but not HOST_COHERENT.
      • Added structure member VmaVulkanFunctions::vkCmdCopyBuffer.
      • Major internal changes in defragmentation algorithm.
      • VmaReplay: added parameters: --DefragmentAfterLine, --DefragmentationFlags.
      • Old interface (structure VmaDefragmentationInfo, function vmaDefragment) is now deprecated.
    • Added buddy algorithm, available for custom pools - flag VMA_POOL_CREATE_BUDDY_ALGORITHM_BIT.
    • Added convenience functions for multiple allocations and deallocations at once, intended for sparse binding resources - functions vmaAllocateMemoryPages, vmaFreeMemoryPages.
    • Added function that tries to resize existing allocation in place: vmaResizeAllocation.
    • Added flags for allocation strategy: VMA_ALLOCATION_CREATE_STRATEGY_BEST_FIT_BIT, VMA_ALLOCATION_CREATE_STRATEGY_WORST_FIT_BIT, VMA_ALLOCATION_CREATE_STRATEGY_FIRST_FIT_BIT, and their aliases: VMA_ALLOCATION_CREATE_STRATEGY_MIN_MEMORY_BIT, VMA_ALLOCATION_CREATE_STRATEGY_MIN_TIME_BIT, VMA_ALLOCATION_CREATE_STRATEGY_MIN_FRAGMENTATION_BIT.

    Minor changes:

    • Changed behavior of allocation functions to return VK_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.
    • VmaReplay: Added support for Windows end of lines.
    • Updated recording CSV file format version to 1.5, to support new functions.
    • 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...
