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.
19 The first system page of the mapping contains ring-buffer statistics and
21 fields of the meta-page is the reader. It contains the sub-buffer ID which can
22 be safely read by the mapper (see ring-buffer-design.rst).
38 When a mapping is in place on a Tracefs ring-buffer, it is not possible to
39 either resize it (either by increasing the entire size of the ring-buffer or
41 the ring buffer data instead of using the copyless swap from the ring buffer.
43 Concurrent readers (either another application mapping that ring-buffer or the
45 the ring-buffer and the output is unpredictable, just like concurrent readers on
