Detailed Description

General statistics from current state of the allocator - total memory usage across all memory heaps and segments.

These are slower to calculate. Use for debugging purposes. See function D3D12MA::Allocator::CalculateStatistics().

HeapType

DetailedStatistics D3D12MA::TotalStatistics::HeapType[5]

One element for each type of heap located at the following indices:

• 0 = D3D12_HEAP_TYPE_DEFAULT
• 1 = D3D12_HEAP_TYPE_UPLOAD
• 2 = D3D12_HEAP_TYPE_READBACK
• 3 = D3D12_HEAP_TYPE_CUSTOM
• 4 = D3D12_HEAP_TYPE_GPU_UPLOAD

MemorySegmentGroup

DetailedStatistics D3D12MA::TotalStatistics::MemorySegmentGroup[2]

One element for each memory segment group located at the following indices:

• 0 = DXGI_MEMORY_SEGMENT_GROUP_LOCAL
• 1 = DXGI_MEMORY_SEGMENT_GROUP_NON_LOCAL

Meaning of these segment groups is:

• When IsUMA() == FALSE (discrete graphics card):
  • DXGI_MEMORY_SEGMENT_GROUP_LOCAL (index 0) represents GPU memory (resources allocated in D3D12_HEAP_TYPE_DEFAULT, D3D12_HEAP_TYPE_GPU_UPLOAD or D3D12_MEMORY_POOL_L1).
  • DXGI_MEMORY_SEGMENT_GROUP_NON_LOCAL (index 1) represents system memory (resources allocated in D3D12_HEAP_TYPE_UPLOAD, D3D12_HEAP_TYPE_READBACK, or D3D12_MEMORY_POOL_L0).
• When IsUMA() == TRUE (integrated graphics chip):
  • DXGI_MEMORY_SEGMENT_GROUP_LOCAL = (index 0) represents memory shared for all the resources.
  • DXGI_MEMORY_SEGMENT_GROUP_NON_LOCAL = (index 1) is unused and always 0.

Total

DetailedStatistics D3D12MA::TotalStatistics::Total

Total statistics from all memory allocated from D3D12.
