cTGP Graphics Power Setting Coming For Uniwill / TUXEDO Laptops With Linux 7.0

The Linux kernel is gaining new capabilities for power management on Uniwill-manufactured laptops, with TUXEDO Computers leading the charge to bring more features into the mainline kernel. The upcoming Linux 7.0 release will include support for adjusting the custom total graphics power (cTGP) setting on compatible laptops.

Uniwill Platform Driver Evolution

The Uniwill laptop platform driver, which landed in Linux 6.19, provides foundational support for laptops from this Taiwanese OEM/ODM manufacturer. TUXEDO Computers has been instrumental in upstreaming these drivers, moving functionality that previously required their out-of-tree kernel modules into the mainline kernel.

Werner Sembach of TUXEDO Computers has been extending the Uniwill driver to expose more hardware features. The latest addition focuses on cTGP control, allowing users to adjust the power limit of their discrete GPUs on supported hardware.

cTGP Power Management

The custom total graphics power setting enables fine-grained control over GPU power consumption. This feature is particularly relevant for laptops with dedicated graphics, where thermal and power constraints often limit performance. By exposing cTGP controls through the kernel, users gain the ability to optimize their system's power profile without relying on proprietary drivers.

The implementation targets laptops featuring NVIDIA GeForce RTX 3000 series or newer mobile GPUs. This covers a significant portion of modern gaming and workstation laptops that use Uniwill-manufactured chassis.

Linux 7.0 Integration

The cTGP patch has been merged into the x86 platform driver's "for-next" Git branch, positioning it for inclusion in the Linux 6.20~7.0 development cycle. This timeline suggests users can expect native cTGP control support in distributions shipping with Linux 7.0, expected later in 2026.

Hardware Compatibility

While the article doesn't specify exact laptop models, the cTGP feature will work with Uniwill-manufactured laptops that include:

• NVIDIA GeForce RTX 3000 series or newer mobile GPUs
• Compatible power delivery systems
• Hardware that supports cTGP functionality

TUXEDO Computers' lineup likely includes several models that will benefit from this feature, given their history of using Uniwill chassis for their Linux-focused laptops.

Benefits for Linux Users

This development represents another step toward making Linux a first-class operating system for high-performance laptops. By moving cTGP control into the mainline kernel, TUXEDO Computers eliminates the need for users to install and maintain out-of-tree kernel modules, reducing complexity and improving system stability.

For enthusiasts and professionals using these laptops, the ability to adjust GPU power limits through standard kernel interfaces opens up new possibilities for performance tuning, thermal management, and battery life optimization.

The ongoing work to upstream Uniwill laptop features demonstrates TUXEDO Computers' commitment to the Linux ecosystem and provides a model for other hardware vendors to follow.
