For example, Schmitt-trigger inputs, high-current output drivers, optical isolators, or combinations of these, may be used to buffer and condition the GPIO signals and to protect board circuitry. Also, higher-level functions are sometimes implemented, such as input debounce , input signal edge detection, and pulse-width modulation (PWM) output.
The eXtensible Host Controller Interface (xHCI) is a technical specification that provides a detailed framework for the functioning of a computer's host controller for Universal Serial Bus (USB). Known alternately as the USB 3.0 host controller specification, xHCI is designed to be backward compatible, supporting a wide range of USB devices ...

Free and open-source drivers are primarily developed on and for Linux by Linux kernel developers, third-party programming enthusiasts and employees of companies such as Advanced Micro Devices. Each driver has five parts: A Linux kernel component DRM; A Linux kernel component KMS driver (the display controller driver)
AMDgpu is an open source device driver for the Linux operating system developed by AMD to support its Radeon lineup of graphics cards (GPUs). It was announced in 2014 as the successor to the previous radeon device driver as part of AMD's new "unified" driver strategy, [3] and was released on April 20, 2015.
Of the four signals, three are driven by the HBA and one by the backplane. Typically, the HBA is a storage controller located inside a server, desktop, rack or workstation computer that interfaces with hard disk drives or solid-state drives to store and retrieve data. It is considered an extension of the general-purpose input/output (GPIO
NSC/AMD Geode CS5535 Southbridge for Geode GX(2) and Geode LX (USB 1.1). Integrates four USB ports, one ATA-66 UDMA controller, one Infrared communication port, one AC'97 controller, one SMBUS controller, one LPC port, as well as GPIO, Power Management, and legacy functional blocks. AMD Geode CS5536 Southbridge for Geode GX and Geode LX (USB 2.0).
SCI from the Embedded Controller to inform the ACPI driver (in the OS) of an ACPI Event; As a core system component, the embedded controller is always on when power is supplied to the mainboard. To communicate with the main computer system, several forms of communication can be used, including ACPI, SMBus, or shared memory.
