# Install Intel® GPU firmware (Optional)

The Embodied Intelligence SDK offers two options for installing Intel® GPU firmware:

- **For platforms with only an integrated GPU (iGPU)**: automatic installation via the [Real-Time Linux](rt_linux.md) method.
- **For platforms with both integrated (iGPU) and discrete GPUs (dGPU)**: manual installation using the instructions provided on this page.

## Dependencies

This firmware is part of a collection of kernel mode drivers
that together enable support for Intel graphics. The backports
collection within <https://github.com/intel-gpu> includes:

- [[i915]](https://github.com/intel-gpu/intel-gpu-i915-backports) - The main graphics driver, Intel® Graphics Driver.
- [[cse]](https://github.com/intel-gpu/intel-gpu-cse-backports) - Intel® Converged Security Engine (Intel® CSE).
- [[pmt]](https://github.com/intel-gpu/intel-gpu-pmt-backports) - Intel® Platform Monitoring Technology (Intel® PMT).
- [[firmware]](https://github.com/intel-gpu/intel-gpu-firmware) - Contains firmware required by Intel® Graphics Driver.

Each project is tagged consistently so when pulling these repositories pull the same tag.

> **Tip:** If Intel® Graphics Driver is disabled, check the grub of cmdline:
>
> ```console
> cat /proc/cmdline | grep i915
> i915.force_probe=*
> ```

## Installation

1. Get the correct Intel® Graphics Driver firmware with the following command:

   ```bash
   wget https://web.git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/i915/mtl_gsc_1.bin --no-check-certificate
   wget https://web.git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/i915/mtl_guc_70.bin --no-check-certificate
   ```

2. Remove the `zst` firmware files with the following command (Optional):

   ```bash
   sudo rm /lib/firmware/i915/mtl_guc_70.bin.zst
   sudo rm /lib/firmware/i915/mtl_gsc_1.bin.zst
   ```

3. Update the Intel® Graphics Driver firmware with the following command:

   ```bash
   sudo cp mtl_guc_70.bin /lib/firmware/i915/
   sudo cp mtl_gsc_1.bin /lib/firmware/i915/
   sudo update-initramfs -u -k $(uname -r)
   ```

4. Reboot.

## Verifying Installation

To verify that the GPU firmwares are installed, run `sudo dmesg | grep firmware`, the result might be similar to the following:
