Hi, We are working on ARM based SOC. Currently we are implementing a efficient tracing mechanism to logs messages from a dedicated MCU.
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. Strangely wringing a single log message in the kernel ring-buffer cost around 6-8ms. Please help to confirm this, or we are doing something wrong. Thanks, Chetan Nanda
