Sorry I still not performed any experimentation due to some coughing type of health problems I just do not understand the patch at all because I don't know C code and > can not tell if the code is better with essentially the same outcome. > Explanation I found on the web says it fixes it because memcpy from libc and thus know how and where align things https://hackaday.com/2022/05/10/data-alignment-across-architectures-the-good-the-bad-and-the-ugly/ >
