Hi Kumaravadivel and welcome to LQ.

I feel you need to add some more description as to what you're trying to do, what you want the result to be, and how you feel you may possibly proceed with working on this.

You wish to create a log, and you say in the kernel. What do you wish to log? Your own information, or information you feel already comes from other sources in the kernel?

You say a circular buffer. How large, how large would each record be? What format would each record be? What would they contain? Do you wish to make the size or contents of the logs be configurable?

How would you proceed: Do you expect to write code to accomplish this? Were you hoping to find an existing capability that you could re-use?

Can you describe what you wish to do better? Can you cite or illustrate an example of what you wish to accomplish? As well as describe what you felt you might do, scripting, coding, or other, to accomplish what you intend to get as a result. And please describe your thinking which has led you to deciding that you wished to create, obtain, or use a kernel circular log buffer.

I just try to create my own circular buffer in Kernel with the size of 16 KB. By default it should be initialized by zeros. I need to store the characters , and every time i entered it shows the full buffer , it need to analyze the events by statistic variables.
