program level, for the operating system: The Buddy (the thread) seems to be in the process of computing, with less IO.The nature of the process is that in a single thread, the user controls a task by itself when the IO block is switched on to another task to execute, to improve efficiency.So we need to find a solution that can meet the following conditions:1. You can control the switch between multiple tasks, save the state of the task before switching (re-run, you can continue based on the pau

Description These format definitions are used to match the pixel format of the traditional PC's image frame buffer. Each pixel occupies 8, 16, 24, or 32 bits. This is the packed-pixel format, which means that each pixel is in the memory. When one of these formats is used, the driver should report the color space to v4l2_colorspace_srgb. Table2-1.
