# GDN-HIP (Gated Delta Net, RDNA4/gfx1201)

Native HIP + rocWMMA kernels for the Gated Delta Net linear-attention path: gdn_prefill/decode (+wmma/chunked), causal_conv1d, gated RMSNorm, with native backward + differentiable training wrappers.

Built with [kernel-builder](https://github.com/huggingface/kernel-builder) for AMD RDNA4 (gfx1201).
Load with the [`kernels`](https://github.com/huggingface/kernels) library:

```python
from kernels import get_kernel
kernel = get_kernel("pat883/gdn-hip")
```

> Requires a ROCm PyTorch build (torch 2.10 / ROCm 7.x) on an RDNA4 card. Built variants:
> `torch210-cxx11-rocm70` and `torch210-cxx11-rocm71`.
