%description
MVGAL (Multi-Vendor GPU Aggregation Layer) enables heterogeneous GPUs
(AMD, NVIDIA, Intel, Moore Threads) to function as a single logical compute
and rendering device.

Features:
- Unified abstraction for multiple GPUs
- Smart scheduling with AFR, SFR, and Hybrid strategies
- DMA-BUF based cross-GPU memory management
- Vulkan layer for transparent API interception
- OpenCL and CUDA support (experimental)
- Daemon for background GPU management
