NettetThe Linux driver implementer’s API guide. The kernel offers a wide variety of interfaces to support the development of device drivers. This document is an only somewhat organized collection of some of those interfaces — it will hopefully get better over time! The available subsections can be seen below. NettetSubsystem drivers using GPIO¶. Note that standard kernel drivers exist for common GPIO tasks and will provide the right in-kernel and userspace APIs/ABIs for the job, and that these drivers can quite easily interconnect with other kernel subsystems using hardware descriptions such as device tree or ACPI:
NettetDescription. This driver register CPU digital temperature package level sensor as a thermal zone with maximum two user mode configurable trip points. Number of trip points depends on the capability of the package. Once the trip point is violated, user mode can receive notification via thermal notification mechanism and can take any action to ... NettetReal Time Clock (RTC) Drivers for Linux. When Linux developers talk about a “Real Time Clock”, they usually mean something that tracks wall clock time and is battery backed …
NettetAll clock drivers, including the Jetson custom clk driver, implement the structure clk_ops. Clock sources and clocks required by devices are defined in the device tree. Clocks are controlled by an R5 called the Boot and Power Management Processor. It runs RTOS software from bpmp.bin. Nettet21. mai 2024 · Powercap Sysfs C Bindings and Utilities.

NettetThe generic thermal sysfs provides a set of interfaces for thermal zone devices (sensors) and thermal cooling devices (fan, processor…) to register with the thermal management solution and to be a part of it. This how-to focuses on enabling new thermal zone and cooling devices to participate in thermal management.
