设备树(DTS:device tree source),字面意思就是一块电路板上设备如上图中CPU、DDR、I2C、GPIO、SPI等,按照树形结构描绘成的一棵树。按照策略和功能分离的思路,就是驱动代码(功能)和设备树DTS配置文件(策略)分开来进行设计,这样针对不同的电路板 ...
在 ARM、RISC-V、PowerPC 以及大量国产化 SoC 平台中,Device Tree(设备树)已经成为 Linux BSP、驱动适配和板级 bring-up 的核心基础设施。很多系统研发工程师日常会改 DTS、排查 probe 失败、修 GPIO 和中断,但如果只停留在“会改节点”的层面,遇到 deferred probe、overlay ...

The Linux USB subsystem has grown from supporting only two different types of devices in the 2.2.7 kernel (mice and keyboards), to over 20 different types of devices in the 2.4 kernel. Linux currently ...
A steady stream of manufacturers are requesting Linux drivers for their hardware, suggesting growing adoption of Linux operating systems among enterprises. According to Greg Kroah-Hartman, Novell ...
One of the highly debated subjects with Windows and Linux is with device support. The two have different methods of how drivers are created and implemented into the operating system. With Windows, ...
