    v2.1.0-beta.1 Stable

    archiver-bot released this 2018-08-27 05:30:53 -05:00 | 1077 commits to master since this release

    Major release after many months of development in "development" branch and features branches. Many new features added, some bugs fixed. API stays backward-compatible.

    Major changes:

    • Added linear allocation algorithm, accessible for custom pools, that can be used as free-at-once, stack, double stack, or ring buffer. See "Linear allocation algorithm" documentation chapter.
      • Added VMA_POOL_CREATE_LINEAR_ALGORITHM_BIT, VMA_ALLOCATION_CREATE_UPPER_ADDRESS_BIT.
    • Added feature to record sequence of calls to the library to a file and replay it using dedicated application. See documentation chapter "Record and replay".
      • Recording: added VmaAllocatorCreateInfo::pRecordSettings.
      • Replaying: added VmaReplay project.
      • Recording file format: added document "docs/Recording file format.md".
    • Improved support for non-coherent memory.
      • Added functions: vmaFlushAllocation, vmaInvalidateAllocation.
      • nonCoherentAtomSize is now respected automatically.
      • Added VmaVulkanFunctions::vkFlushMappedMemoryRanges, vkInvalidateMappedMemoryRanges.
    • Improved debug features related to detecting incorrect mapped memory usage. See documentation chapter "Debugging incorrect memory usage".
      • Added debug macro VMA_DEBUG_DETECT_CORRUPTION, functions vmaCheckCorruption, vmaCheckPoolCorruption.
      • Added debug macro VMA_DEBUG_INITIALIZE_ALLOCATIONS to initialize contents of allocations with a bit pattern.
      • Changed behavior of VMA_DEBUG_MARGIN macro - it now adds margin also before first and after last allocation in a block.
    • Changed format of JSON dump returned by vmaBuildStatsString (not backward compatible!).
      • Custom pools and memory blocks now have IDs that don't change after sorting.
      • Added properties: "CreationFrameIndex", "LastUseFrameIndex", "Usage".
      • Changed VmaDumpVis tool to use these new properties for better coloring.
      • Changed behavior of vmaGetAllocationInfo and vmaTouchAllocation to update allocation.lastUseFrameIndex even if allocation cannot become lost.

    Minor changes:

    • Changes in custom pools:
      • Added new structure member VmaPoolStats::blockCount.
      • Changed behavior of VmaPoolCreateInfo::blockSize = 0 (default) - it now means that pool may use variable block sizes, just like default pools do.
    • Improved logic of vmaFindMemoryTypeIndex for some cases, especially integrated GPUs.
    • VulkanSample application: Removed dependency on external library MathFu. Added own vector and matrix structures.
    • Changes that improve compatibility with various platforms, including: Visual Studio 2012, 32-bit code, C compilers.
      • Changed usage of "VK_KHR_dedicated_allocation" extension in the code to be optional, driven by macro VMA_DEDICATED_ALLOCATION, for compatibility with Android.
    • Many additions and fixes in documentation, including description of new features, as well as "Validation layer warnings".
    • Other bugfixes.
