In Linux, every directory has its own purpose for its existence. The same is true for thesysfsdirectory. Thesysfsentries are used by the kernel to export the information to processes in the user domain and to get input from the user. These entries travel through the file system to find th...
sysfs is a feature of the Linux 2.6 kernel that allows kernel code to export information to user processes via an in-memory filesystem. The organization of the filesystem directory hierarchy is strict, and based the internal organization of kernel data structures. The files that are created in ...
that are not present in the obsolete sysfs interface (like event polling, setting/reading multiple values at once or open-source and open-drain GPIOs). Unfortunately interacting with the linux device file can no longer be done using only standard command-line tools. This is the reason for cre...
linux gpio控制之sysfs接口 在3.14及之后的linux中对gpio提供了sysfs接口,说明文档:Documents/gpio/sysfs.txt。 Platforms which use the "gpiolib" implementors framework may choose to configure a sysfs user interface to GPIOs.This is different from the debugfs interface, since it provides control over ...
