NVIDIA Tegra fuse and SoC identification driver

Reads the on-chip electronic fuses found on NVIDIA Tegra system-on-chips, which encode the chip's revision, speed grade, security settings, and unique identifiers. It covers the full Tegra lineage from the original Tegra20 through Tegra234 and Tegra241, the SoCs powering NVIDIA's Jetson embedded modules, in-car systems, and the Nintendo Switch.

recommendation

It should stay because the hardware is still being sold new: NVIDIA's published lifecycle has Jetson AGX Orin and Orin NX/Nano modules available through January 2032, and the driver itself is under active maintenance, with patches landing on the linux-tegra list as recently as October 2025 to fix Tegra194/Tegra234 ACPI behavior. It is foundational infrastructure for any Tegra-based Linux system, so removal is not on the table.

sources

  1. lore.kernel.org

    Upstream activity is current: March 24, 2026 patch touching fuse-tegra.c shows ongoing maintenance rather than deprecation.

  2. lore.kernel.org

    Driver received a 2025 bug-fix/stable-worthy patch for Tegra194/Tegra234 ACPI behavior, indicating active field use on modern Tegra SoCs.

  3. developer.nvidia.com

    NVIDIA lists Jetson AGX Orin and Orin NX/Nano modules as available through January 2032, with Xavier NX and TX2 NX through 2028, so Tegra hardware covered by this driver family was still sold new in 2025.

  4. docs.nvidia.com

    NVIDIA's Jetson Linux Developer Guide updated June 26, 2025 documents the actively supported Jetson platform and modules that rely on Tegra SoCs.

codex reasoning notes (technical)

Real driver directory: local shell inspection of drivers/soc/tegra/fuse and drivers/soc/tegra/Kconfig showed built kernel code for SOC_TEGRA_FUSE across Tegra20/30/114/124/132/210/186/194/234/241, including current Tegra234/241 support. lore_activity (tool) on drivers/soc/tegra/fuse/fuse-tegra.c returned 2025-10 and 2026-03 linux-tegra patches, with no removal/deprecation evidence; the directory-level lore_file_timeline query returned no matches, so file-level lore evidence was used instead. Web search (tool) found NVIDIA lifecycle and Jetson Linux docs showing current Jetson/Orin availability. Kept, not annotated: active upstream fixes plus hardware still on sale. last_widely_available_year is set to 2032 based on the current Orin module lifecycle horizon; deployments are medium because Tegra/Jetson remains relevant in embedded/edge systems but is not broad commodity PC hardware.
