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
