4 Tracefs ring-buffer memory mapping
11 Tracefs ring-buffer memory map provides an efficient method to stream data
12 as no memory copy is necessary. The application mapping the ring-buffer becomes
13 then a consumer for that ring-buffer, in a similar fashion to trace_pipe.
15 Memory mapping setup
17 The mapping works with a mmap() of the trace_pipe_raw interface.
19 The first system page of the mapping contains ring-buffer statistics and
20 description. It is referred to as the meta-page. One of the most important
21 fields of the meta-page is the reader. It contains the sub-buffer ID which can
