Qualcomm Snapdragon X2 GPU Firmware Now Upstreamed, Enabling Open-Source Driver Support

The Qualcomm Snapdragon X2 Elite laptop SoC has taken a significant step toward better Linux support with the recent upstreaming of GPU firmware files to the linux-firmware.git repository. This development, committed by Qualcomm engineers last week, provides the necessary firmware binaries that enable the open-source Mesa graphics stack to properly support the Adreno X2-85 GPU found in these new ARM-based laptop processors.

This upstreaming effort comes at an opportune time, following the inclusion of X2-85 GPU support in the Linux kernel's MSM DRM driver with version 6.19. The Mesa 26.0 graphics stack has also gained initial support for these Gen8 Adreno graphics, creating a complete open-source graphics pipeline for the Snapdragon X2 platform. With the firmware now available in the standard Linux Firmware Git repository, developers and users can expect more straightforward integration and support for these GPUs in Linux distributions.

This marks a notable improvement over the previous generation Snapdragon X1 platform, where GPU firmware support was more fragmented. For the X1, most laptop models required extracting firmware from Windows on ARM installations, creating a dependency on proprietary OEM firmware that complicated Linux deployment. The Snapdragon X2's approach of having GPU firmware upstreamed eliminates this particular hurdle, representing a more open and maintainable solution for the Linux ecosystem.

However, it's important to note that while the GPU firmware situation has improved significantly, other component firmware for the Snapdragon X2 platform may still depend on OEM-provided binaries. These could require extraction from Windows installations or, ideally, be upstreamed by OEMs to the linux-firmware.git repository. The GPU firmware upstreaming sets a positive precedent, and it remains to be seen whether other firmware components will follow this more open approach.

The commit that added these GPU firmware binaries specifically targets the Snapdragon X2 "Glymur" hardware, ensuring that the firmware matches the exact GPU configuration of these new SoCs. This level of specificity is crucial for proper hardware initialization and optimal performance in Linux environments.

For Linux users and developers working with ARM-based laptops, this firmware upstreaming represents meaningful progress toward a more open and accessible platform. The combination of kernel support, Mesa driver support, and now proper firmware availability creates a more complete open-source graphics solution for the Snapdragon X2 Elite, potentially making these devices more attractive for Linux deployments and development work.
