Acpi 80860f14 📌
While modern Windows versions often have inbox drivers for this controller, older systems like Windows 7 can be a major headache. Users have reported seeing the device in Device Manager with a yellow exclamation mark and the Hardware ID ACPI\80860F14 . The main problems are two-fold:
Your hard drive ( /dev/mmcblk0 ) doesn't show up during boot.
If Windows Update fails to find a driver for ACPI 80860F14 :
static const struct acpi_device_id i2c_designware_acpi_ids[] = "INT33C2", ... , "80860F14", ... , // Intel Bay Trail I2C "808622C1", ... , // Intel Cherry Trail I2C Acpi 80860f14
| Issue | Likely Cause | |-------|----------------| | I2C device (touchscreen, sensor) not detected | Driver not binding to 80860F14 | | i2c_dw probe failure | Missing _CID or invalid ACPI resources | | System hang after suspend | LPSS power domain not properly reset |
| Unique ID (UID) | Interface Type | Common Use Case | | :---: | :--- | :--- | | | eMMC 4.5 Controller | The primary internal storage for the operating system, found on many low-cost tablets and laptops. | | UID 2 | SDIO (Secure Digital I/O) Bus | Used for connecting internal devices like Wi-Fi, Bluetooth, or GPS modules, and sometimes an additional SD card slot. | | UID 3 | SD (Secure Digital) Host Controller | The standard external SD card slot for removable media, found on many laptops and NUCs (Next Unit of Computing). |
The ACPI Plug and Play Hardware ID 80860F14 corresponds to a proprietary Intel device found primarily on Bay Trail and Cherry Trail system-on-chips (SoCs). This paper examines the device's identification, its role in power management and I2C controller operation, and the challenges it presents for open-source operating systems. While modern Windows versions often have inbox drivers
Note: The Linux kernel often maps 80860F14 to the dw_i2c (DesignWare I2C) driver via the i2c-designware-platform driver.
The string ACPI\80860F14 follows a specific naming convention:
The ACPI 80860F14 device is an essential component of modern computer systems, providing a range of functions, from power management and security to remote management. By understanding the intricacies of this device, developers, system administrators, and tech enthusiasts can gain a deeper appreciation for the complexities of ACPI and its role in shaping the modern computing landscape. Whether you're working on optimizing system performance, enhancing security, or exploring new applications, the ACPI 80860F14 device is an fascinating topic to explore. If Windows Update fails to find a driver
: The Windows Device Manager presents a yellow exclamation icon, categorizing the hardware ID under "Other Devices".
ACPI provides a standardized way for the operating system to communicate with hardware components, such as the CPU, memory, and peripherals, to manage power consumption, temperature, and performance. This interface enables features like dynamic voltage and frequency scaling, power gating, and thermal management.
