Hi, <br><br>We are working on ARM based SOC. <br>Currently we are implementing a efficient tracing mechanism to logs messages from a dedicated MCU.<br><br>For this, we share a circular buffer between ARM and MCU and messages stored in the buffer will be put into kernel ring-buffer and then output via dmesg call.<br>
Strangely wringing a single log message in the kernel ring-buffer cost around 6-8ms.<br><br>Please help to confirm this, or we are doing something wrong.<br><br>Thanks,<br>Chetan Nanda<br>
