compared the linux directory before and after the power plugging, but there was no clue when I looked for it for a long time. Why did I check CPU and memory for commands, check the power supply and there will be no command? Later, I found that this may not exist! I don't know the driver, I don't know the hardware, and I can't use the scripts written by others. I try to understand it. The following is your understanding. Please refer to Hai Han for errors. The first thing we can understand is th

The basic idea is to implement a parent device for the public part of these functions, in order to share certain system resources and functions, then each child function is implemented as its sub device, so that both resources and code are shared, and a reasonable device hierarchy can be achieved, the main use of the API is: Mfd_add_devices (), Mfd_remove_devices (), mfd_cell_enable (), mfd_cell_disable (), Mfd_clone_cell ().

Use MRTG to monitor CPU temperature-Linux Enterprise Application-Linux server application information. The following is a detailed description. It's time to roll again in summer ~ I believe many people are concerned about whether their CPU will go on strike due to overheating? Is there any software under Linux that can monitor the temperature? That is lm-sensor. How can I install it? If your core version is 2.2.X Download the i2c and lm-sensor kits.
