# qcom-firmware-updater.sh

Update Adreno GPU firmware on Snapdragon X Elite / X Plus laptops from Qualcomm's Windows Graphics Driver package in Linux.

> **Early release.** Always use `--dry-run` first to review changes before installing.

## Why

My goal is to keep the firmware up to date without requiring a dedicated Windows partition. The scripts retrieve the official Qualcomm Windows drivers and perform the firmware update from within a Linux environment.

This script:

- Downloads and extracts only the 17 firmware files Linux needs (~20MB)
- Cleans up Windows-only files (DLLs, SYS, EXE, CAT, INF, etc.)
- Compares checksums before installing to avoid unnecessary writes
- Updates initramfs automatically if display firmware changes
- Auto-detects your device from `/proc/device-tree/model`

## Quick run

```bash

curl -fsSL https://raw.githubusercontent.com/alejandroqh/qcom-firmware-updater/main/qcom-firmware-updater.sh | bash

```

The script will guide you through downloading and installing the latest firmware.

## Supported devices

Auto-detected from `/proc/device-tree/model`:

For unlisted devices, use `--device-path <soc/oem/board>`.

## Dependencies

```bash
sudo apt install 7zip msitools unzip curl
```

- `7zip` — extract WiX bootstrapper EXE and embedded CAB archives
- `msitools` — extract MSI with original filenames (7z mangles them into WiX internal IDs)
- `unzip` — extract outer ZIP from Qualcomm
- `curl` — download from URL (only needed with `--url`)

## Usage

```bash
# From a local ZIP (downloaded from Qualcomm Software Center)
./qcom-firmware-updater.sh ~/Downloads/Windows_Graphics_Driver.Core.260228031.0.148.0.Windows-ARM64.zip

# From a local EXE (already extracted from ZIP)
./qcom-firmware-updater.sh ~/Downloads/Qualcomm_Adreno_Driver-v31.0.148.0.exe

# Download directly from a URL
./qcom-firmware-updater.sh --url "https://softwarecenter.qualcomm.com/api/download/software/tools/Windows_Graphics_Driver/Windows/ARM64/260228031.0.148.0/Windows_Graphics_Driver.Core.260228031.0.148.0.Windows-ARM64.zip"

# Dry run — compare only, don't install (no sudo needed)
./qcom-firmware-updater.sh --dry-run ~/Downloads/Windows_Graphics_Driver.Core.*.zip

# Override device detection for an unlisted machine
./qcom-firmware-updater.sh --device-path x1e80100/dell/xps13-9345 driver.zip

# List supported devices
./qcom-firmware-updater.sh --list-devices
```

## How it works

The Qualcomm Graphics Driver package is a nested archive:

```
ZIP
 └── Qualcomm_Adreno_Driver-v*.exe    (WiX Burn bootstrapper, PE32)
      ├── UX payloads (manifest, DLL, icons)   ← extracted by 7z
      └── Attached container (CAB tail)         ← extracted by dd
           └── gfx_drivers_8380.msi             ← extracted by 7z
                └── QCDrivers/Drivers/.../       ← extracted by msiextract
                     ├── *.mbn, *.bin  (firmware) ✓
                     ├── *.dll, *.sys  (Windows)  ✗
                     └── *.cat, *.inf  (metadata) ✗
```

The extraction pipeline:

1. **ZIP → EXE** — `unzip` extracts the outer archive
2. **EXE → CAB** — `7z` extracts the WiX bootstrapper to read the tail size, then `dd` extracts the attached Microsoft Cabinet from the end of the EXE
3. **CAB → MSI** — `7z` extracts the Cabinet to get the MSI installer
4. **MSI → files** — `msiextract` (not `7z`) extracts with real filenames preserved

## Firmware files

The 17 files Linux uses from the Graphics Driver package:

| File | Purpose | Size |
|------|---------|------|
| `qcav1e8380.mbn` | AV1 video codec firmware | 4.4 MB |
| `qcdxkmbase8380.bin` | GPU kernel microcode (base) | 123 KB |
| `qcdxkmbase8380_{68,110,150}.bin` | GPU kernel microcode (OPP variants) | ~123 KB each |
| `qcdxkmbase8380_pa.bin` | GPU kernel microcode (power-adjusted base) | 124 KB |
| `qcdxkmbase8380_pa_{67,111,140}.bin` | GPU kernel microcode (PA OPP variants) | ~124 KB each |
| `qcdxkmsuc8380.mbn` | Display KMS microcontroller | 12 KB |
| `qcdxkmsucpurwa.mbn` | Display KMS (PURWA variant) | 12 KB |
| `qcvss8380.mbn` | Video subsystem firmware | 2.3 MB |
| `qcvss8380_pa.mbn` | Video subsystem (power-adjusted) | 2.3 MB |
| `sequence_manifest.bin` | Firmware load sequence descriptor | 2.8 KB |
| `unified_kbcs_{32,64}.bin` | Shader bitcode cache (32/64-bit) | 3.1 MB each |
| `unified_ksqs.bin` | Shader queue setup data | 453 KB |

Core GPU boot firmware (`gen71500_sqe.fw`, `gen71500_gmu.bin`, `gen71500_zap.mbn`) comes from the `linux-firmware` package and is **not** managed by this script.

## What happens on install

1. Backs up current firmware to `<firmware_dir>.bak-YYYYMMDD-HHMMSS/`
2. Copies changed/new firmware files with `root:root 0644` permissions
3. Removes Windows-only files (`.dll`, `.sys`, `.exe`, `.cat`, `.inf`, `.json`, `.so`, `.txt`) from the firmware directory
4. Runs `update-initramfs` if display KMS firmware (`qcdxkmsuc8380.mbn`) changed

## Complementary to qcom-firmware-extract

[qcom-firmware-extract](https://code.launchpad.net/ubuntu/+source/qcom-firmware-extract) pulls DSP firmware from a Windows partition, while this script pulls GPU, display, and video firmware from Qualcomm's driver installer, no Windows partition needed.
