## 🔧 Build Instructions

### Prerequisites (Built from Source)

Ubuntu 20.04 on POWER8 has broken packages. All prerequisites built from source:

```bash
# cmake 3.25.3
wget https://github.com/Kitware/CMake/releases/download/v3.25.3/cmake-3.25.3.tar.gz
tar xzf cmake-3.25.3.tar.gz && cd cmake-3.25.3
./bootstrap --prefix=/usr/local -- -DCMAKE_USE_OPENSSL=OFF
make -j$(nproc) && sudo make install

# numactl 2.0.16
wget https://github.com/numactl/numactl/releases/download/v2.0.16/numactl-2.0.16.tar.gz
tar xzf numactl-2.0.16.tar.gz && cd numactl-2.0.16
./configure --prefix=/usr/local && make -j$(nproc) && sudo make install

# libdrm 2.4.100 (AMD only)
wget https://dri.freedesktop.org/libdrm/libdrm-2.4.100.tar.bz2
tar xjf libdrm-2.4.100.tar.bz2 && cd libdrm-2.4.100
./configure --prefix=/usr/local --disable-nouveau --enable-amdgpu
make -j$(nproc) && sudo make install
```

### Build ROCT-Thunk-Interface

```bash
wget https://github.com/RadeonOpenCompute/ROCT-Thunk-Interface/archive/refs/tags/rocm-5.7.1.tar.gz
tar xzf rocm-5.7.1.tar.gz && cd ROCT-Thunk-Interface-rocm-5.7.1
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/opt/rocm
make -j$(nproc) && sudo make install
```

### Build LLVM/Clang with AMDGPU

    -DLLVM_TARGETS_TO_BUILD="AMDGPU;PowerPC" \
    -DLLVM_ENABLE_ASSERTIONS=OFF

make -j64 && sudo make install  # 64 threads optimal on POWER8
```

### Build ROCR-Runtime

```bash
wget https://github.com/RadeonOpenCompute/ROCR-Runtime/archive/refs/tags/rocm-5.7.1.tar.gz
tar xzf rocm-5.7.1.tar.gz && cd ROCR-Runtime-rocm-5.7.1
mkdir build && cd build

cmake ../src \
    -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_INSTALL_PREFIX=/opt/rocm \
    -DCMAKE_C_COMPILER=/opt/rocm/llvm/bin/clang \
    -DCMAKE_CXX_COMPILER=/opt/rocm/llvm/bin/clang++

make -j32 && sudo make install
```

## ✅ Verification

```bash
# Check Clang
$ /opt/rocm/llvm/bin/clang --version
clang version 17.0.0
Target: powerpc64le-unknown-linux-gnu

# Check libraries
ls -la /opt/rocm/lib/libhsa*
```

## 🎮 Supported AMD GPUs

| Architecture | GPUs | Status |
|-------------|------|--------|
| **RDNA 2/3** | RX 6800, 7900 XTX | Full ROCm |
| **RDNA 1** | RX 5700 | Full ROCm |
| **Polaris** | RX 580, 480 | Legacy (5.7.x) |
| **Vega** | Radeon VII, MI50 | Full ROCm |

## 🔌 OCuLink Connection

Same method as NVIDIA GPUs:

```
┌─────────────────────┐         ┌──────────────────────┐
│   IBM POWER8 S824   │         │   External GPU       │
│  ┌───────────────┐  │ OCuLink │  ┌────────────────┐  │
│  │ Supermicro    │◄─┼─────────┼──│ Minisforum DEG1│  │
│  │ AOC-SLG3-2E4T │  │ Cable   │  │ + RX 580       │  │
│  └───────────────┘  │         │  └────────────────┘  │
└─────────────────────┘         └──────────────────────┘
```

## 🤔 Why ROCm on POWER8?

1. **True Open Source** - AMD's compute stack is fully open
2. **No Vendor Lock-in** - HIP code runs on AMD or NVIDIA
3. **Affordable GPUs** - Polaris/Vega cards are cheap
4. **576GB RAM** - Massive system memory complements GPU
5. **Alternative Ecosystem** - Not dependent on NVIDIA
