GPU memory management

Structs§

  • Coherent
    Coherent marker.
  • Data
    Full speed GPU access. Optimal for render targets and persistent resources. Avoid memory with host access.
  • DedicatedAllocator
    Dedicated memory allocator that uses memory object per allocation requested.
  • DedicatedBlock
    Memory block allocated from DedicatedAllocator
  • Download
    GPU to CPU data flow with mapping. Used for copying data from Data memory to be read by the host. Host access is guaranteed.
  • Dynamic
    CPU to GPU data flow with update commands. Used for dynamic buffer data, typically constant buffers. Host access is guaranteed. Prefers memory with fast GPU access.
  • DynamicAllocator
    No-fragmentation allocator. Suitable for any type of small allocations. Every freed block can be reused.
  • DynamicBlock
    Memory block allocated from DynamicAllocator
  • DynamicConfig
    Config for DynamicAllocator.
  • Heaps
    Heaps available on particular physical device.
  • HeapsConfig
    Config for Heaps allocator.
  • LinearAllocator
    Linear allocator that return memory from chunk sequentially. It keeps only number of bytes allocated from each chunk. Once chunk is exhausted it is placed into list. When all blocks allocated from head of that list are freed, head is freed as well.
  • LinearBlock
    Memory block allocated from LinearAllocator
  • LinearConfig
    Config for LinearAllocator.
  • MappedRange
    Represents range of the memory mapped to the host. Provides methods for safer host access to the memory.
  • MaybeCoherent
    Value that contains either coherent marker or non-coherent marker.
  • Memory
    Memory object wrapper. Contains size and properties of the memory.
  • MemoryBlock
    Memory block allocated from Heaps.
  • MemoryHeapUtilization
    Memory utilization of one heap.
  • MemoryTypeUtilization
    Memory utilization of one type.
  • MemoryUtilization
    Memory utilization stats.
  • NonCoherent
    Non-coherent marker.
  • TotalMemoryUtilization
    Total memory utilization.
  • Upload
    CPU to GPU data flow with mapping. Used for staging data before copying to the Data memory. Host access is guaranteed.

Traits§

  • Allocator
    Allocator trait implemented for various allocators.
  • Block
    Block that owns a Range of the Memory. Implementor must ensure that there can’t be any other blocks with overlapping range (either through type system or safety notes for unsafe functions). Provides access to safe memory range mapping.
  • MemoryUsage
    Memory usage trait.
  • Write
    Trait for memory region suitable for host writes.
