Please be ca= utious when sharing information or opening attachments especially from unkn= own senders. Refer to our intranet guide<https://intranet-content.infineon.= com/explore/aboutinfineon/rules/informationsecurity/ug/SocialEngineering/Pa= ges/SocialEngineeringElements_en.aspx> to help you identify Phishing email. Dear AMD, ITE, OEM partners, Linux and FreeBSD maintainers, this email describes a structural hardware support gap on modern AMD-based = systems, affecting all Linux distributions and FreeBSD, specifically regard= ing ITE Super-I/O chips, sensor access, fan control, and power management. This is not a configuration problem and not distribution-specific. It is a missing official vendor-supported driver and integration stack. ________________________________ 1. Affected platforms (representative) * Operating systems * All Linux distributions (Ubuntu, Linux Mint, Debian, Fedora, Arch,= openSUSE, etc.) * FreeBSD * Hardware * CPU: AMD Ryzen 6000 / 7000 / 8000 series (desktop, mobile, HS/HX) * GPU: AMD Radeon iGPU/dGPU (RDNA2 / RDNA3, e.g. 780M) * Mainboards, laptops and mini-PCs using ITE Super-I/O chips (IT86xx / IT87xx / IT89xx families) ________________________________ 2. Observed problem (Linux & FreeBSD) On all Linux distributions and FreeBSD: * ITE Super-I/O chips are detected but unsupported * Typical output: ITE IT86xx detected (to-be-written) * No official driver for: * motherboard temperatures * voltages * fan RPM * PWM fan control * CPU and GPU telemetry is fragmented and inconsistent * Tools such as: * lm-sensors, psensor, fancontrol (Linux) * sysctl, hwmon, powerd (FreeBSD) cannot operate safely without vendor support * Users are forced to: * rely on BIOS-only fan control * use experimental or reverse-engineered drivers * accept missing thermal visibility This leads to: * reduced system safety * unnecessary fan noise * poor power efficiency * blocked adoption for non-technical users ________________________________ 3. Why this works on Windows (important context) On Windows systems: * ITE provides proprietary reference drivers to OEMs * OEMs integrate: * ITE drivers * Embedded Controller (EC) firmware * ACPI tables * Microsoft distributes these drivers via Windows Update On Linux and FreeBSD: * No public register documentation * No official vendor drivers * No OEM-exposed ACPI/EC interfaces * Community developers cannot implement safe, complete support ________________________________ 4. Root cause (clear responsibility split) * ITE * No public Super-I/O register specifications * No official Linux or FreeBSD drivers * OEMs * Ship Linux/FreeBSD-capable hardware without sensor/fan support * Do not expose EC/ACPI interfaces for non-Windows systems * AMD * No unified vendor-supported control stack for Linux and FreeBSD * No official repository bundling CPU, GPU, sensor and power control ________________________________ 5. Proposed solution (realistic and actionable) A) Official AMD-supported repository * Linux: official AMD repository (PPA / repo) * FreeBSD: official AMD packages/ports Containing: * CPU power and thermal telemetry * GPU telemetry and power limits * OEM-approved sensor interfaces * Safe fan control framework ________________________________ B) Official ITE support for Unix-like systems One of the following: * Public Super-I/O register documentation or * Vendor-maintained drivers for Linux and FreeBSD or * OEM-mediated abstraction layer shared across platforms ________________________________ C) Unified user-space control framework Available on: * Linux (all distributions) * FreeBSD With: * Four fixed profiles: * Power saving * Quiet / Office * Balanced * Maximum performance * Optional automatic mode * Manual overrides for advanced users * Safe defaults for families and seniors ________________________________ 6. Why this matters * Modern AMD hardware is powerful but artificially limited on Linux and= FreeBSD * The issue affects all distributions, not just one ecosystem * Lack of official hardware control blocks: * OEM Linux offerings * FreeBSD workstation and server use * long-term stable systems * This is a systemic vendor-level gap, not a community failure ________________________________ 7. Request We ask AMD, ITE and OEM partners to: * treat Linux and FreeBSD as first-class platforms * provide an official, supported hardware control stack * stop forcing users and developers into unsafe reverse engineering * coordinate with kernel, hwmon and FreeBSD maintainers We are willing to provide logs, testing feedback and structured reports.
