Linux Process Scheduling 1. Program vs Process A program is an executable image of a sequence of code and data stored on a disk. It is a static object. A process is an execution program and a dynamic entity. 2. Four Elements of a Linux Process there

There are two types of libraries: Dynamic and Static. Dynamic files are usually suffixed with. So, and static files are suffixed with.. For example, libtest. So libtest.. To use libraries of different versions in the same system, you can add the

Linux Device Driver Model Bus Macro bus_attr   Create the bus_creat_file function for the device property of the bus. The format is as follows: Int bus_create_file (struct bus_type * bus, struct bus_attribute * ATTR){Int error;If (bus_get (bus

Linux Device Driver: top half and bottom half of interrupt handling The interruption of the device will interrupt the normal scheduling and operation of processes in the kernel. The system's pursuit of higher throughput is bound to require the

Common programming errors of Embedded Linux drivers 1. Warning: function declaration isn' t a prototypeThis kind of error is also very common, mainly for some function fixed format errors. For example, int function () is renamed as int function

Linux memory management A process is a program running in a virtual address space. Any program running in Linux is a process. Most processes require virtual memory. Linux supports Virtual Memory, that is, the disk is used as the ram extension, and

Nor Flash Driver Design in Embedded Linux The previous section details the MTD subsystem principles. This section describes the norflash Driver Design in embedded Linux. There are MTD character devices and MTD Block devices on the MTD device layer. 1

Find Find is a very effective tool that can traverse the current directory or even the entire file system to find some files or directories.Main options:-Name: searches for files by file name-Perm searches for Objects Based on file

Note: The original header file is missing and can be added later. There are two types of timers in Linux: 1. Alarm Alarm () and signal () are enough if they are not required to be accurate. Unsigned int alarm (unsigned int seconds) Function

In Linux, many functions are loaded into the kernel only when necessary through the module method. In this way, the kernel can be simplified to improve efficiency and maintain greater flexibility. These Dynamically Loaded modules are usually system
