Hi,
I'am using ftrace to trace my system for a few minutes. For that I configured the trace buffer via buffer_size_kb file to 100000 kb so 200000 for 2 CPUs. After tracing my system the trace size is 500MB. Why the allocated size for the trace buffer (200 MB) is not the same of the trace file (500 MB) ?
and is it convenient to allocate such a big size for the buffer?
Best regards
