# PCILeech Firmware Generator

[![CI](https://github.com/ramseymcgrath/PCILeechFWGenerator/workflows/CI/badge.svg)](https://github.com/ramseymcgrath/PCILeechFWGenerator/actions)

Generate authentic PCIe DMA firmware from real donor hardware with a single command. This tool extracts donor configurations from a local device and generates unique PCILeech FPGA bitstreams (and optionally flashes a DMA card over USB-JTAG).

> [!WARNING]
> This tool requires *real* hardware. The templates are built using the device identifiers directly from a donor card and placeholder values are explicitly avoided. Using your own donor device ensures your firmware will be unique.

## ✨ Key Features

- **Donor Hardware Analysis**: Extract real PCIe device configurations and register maps
- **Full 4KB Config-Space Shadow**: Complete configuration space emulation with overlay RAM
- **MSI-X Table Replication**: Exact replication of MSI-X tables from donor devices
- **Deterministic Variance Seeding**: Consistent hardware variance based on device serial number
- **Advanced SystemVerilog Generation**: Comprehensive PCIe device controller with modular architecture
- **Active Device**: Interrupts implemented to signal device is active (VGK bypass)
- **Memory Overlay Mapping**: Memory. Overlayed. Mapped
- **Interactive TUI**: Modern text-based interface with real-time monitoring and guided workflows
- **Automated Build Pipeline**: Containerized synthesis and bitstream generation
- **Automated Testing and Validation**: Build is continually tested to ensure build quality
- **USB-JTAG Flashing**: Direct firmware deployment to DMA boards

## 🚀 Quick Start

### Installation

```bash
# Install with TUI support (recommended)
pip install pcileechfwgenerator[tui]

# Install sudo wrapper scripts for easier usage
wget https://raw.githubusercontent.com/ramseymcgrath/PCILeechFWGenerator/refs/heads/main/install-sudo-wrapper.sh
./install-sudo-wrapper.sh

# Load required kernel modules
sudo modprobe vfio vfio-pci
```

### Requirements

- **Python ≥ 3.9**
- **Donor PCIe card** (any inexpensive NIC, sound, or capture card)
- **Linux OS** (You need this)

### Optional

- **Podman** (_not Docker_ - required for proper PCIe device mounting) You use podman or run the python locally. *You must use linux for either option
- **DMA board** (pcileech_75t484_x1, pcileech_35t325_x4, or pcileech_100t484_x1) You don't need to flash your firmware with this tooling but you can.
- **Vivado Studio** (2022.2+ for synthesis and bitstream generation) You can use a locally generated Vivado project or insert the files into an existing one.


### Basic Usage

```bash
# Development from repository
git clone https://github.com/ramseymcgrath/PCILeechFWGenerator.git
cd PCILeechFWGenerator
# or pip install
pip3 install pcileechfwgenerator

# Interactive TUI (recommended for first-time users)
pcileech-tui-sudo

# CLI interface
pcileech-generate build

# Local python build
python3 -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt
sudo -E python3 generate.py
```

### Flashing Firmware

```bash
# Flash to DMA board
pcileech-generate flash output/firmware.bin --board pcileech_75t484_x1

# Or use usbloader directly
usbloader -f output/firmware.bin

```

## 🔧 Troubleshooting

### VFIO Setup Issues

> [!WARNING]
> Avoid using on-board devices (audio, graphics cards) for donor info. The VFIO process can lock the bus during extraction and cause system reboots.


The most common issues involve VFIO (Virtual Function I/O) configuration. Use the built-in diagnostic tool:

```bash
# Check VFIO setup and device compatibility
./vfio_setup_checker.py

# Check a specific device
./vfio_setup_checker.py 0000:03:00.0

# Interactive mode with guided fixes
./vfio_setup_checker.py --interactive

# Generate automated fix script
./vfio_setup_checker.py --generate-script
```

### Common VFIO Problems

**1. IOMMU not enabled in BIOS/UEFI**
```bash
# Enable VT-d (Intel) or AMD-Vi (AMD) in BIOS settings
# Then add to /etc/default/grub GRUB_CMDLINE_LINUX:
# For Intel: intel_iommu=on
# For AMD: amd_iommu=on
sudo update-grub && sudo reboot
```

**2. VFIO modules not loaded**
```bash
sudo modprobe vfio vfio_pci vfio_iommu_type1
```

**3. Device not in IOMMU group**
```bash
# Check IOMMU groups
find /sys/kernel/iommu_groups/ -name '*' -type l | grep YOUR_DEVICE_BDF
```

**4. Permission issues**
```bash
# Add user to required groups
sudo usermod -a -G vfio $USER
sudo usermod -a -G dialout $USER  # For USB-JTAG access
```

### Installation Issues

```bash
# If pip installation fails
pip install --upgrade pip setuptools wheel
pip install pcileechfwgenerator[tui]

# For TUI dependencies
pip install textual rich psutil watchdog

# Container issues
podman --version
podman info | grep rootless
```

### Templating issues

If you run into issues with your vivado project file formatting, first clear out all your cached files and rerun. Otherwise try pulling a copy of the pcileech repo directly and then inserting the generator output in.

## 🧹 Cleanup & Safety

- **Rebind donors**: Use TUI/CLI to rebind donor devices to original drivers
- **Keep firmware private**: Generated firmware contains real device identifiers
- **Use isolated build environments**: Never build on production systems
- **Container cleanup**: `podman rmi pcileechfwgenerator:latest`
