+	selects either tracepoint event(s) or a hardware trace PMU
+	(e.g. Intel PT or CoreSight).
+
+	- tracepoint filters
+
+	In the case of tracepoints, multiple '--filter' options are combined
 	using '&&'.
 
+	- address filters
+
+	A hardware trace PMU advertises its ability to accept a number of
+	address filters	by specifying a non-zero value in
+	/sys/bus/event_source/devices/<pmu>/nr_addr_filters.
+
+	Address filters have the format:
+
+	filter|start|stop|tracestop <start> [/ <size>] [@<file name>]
+
+	Where:
+	- 'filter': defines a region that will be traced.
+	- 'start': defines an address at which tracing will begin.
+	- 'stop': defines an address at which tracing will stop.
+	- 'tracestop': defines a region in which tracing will stop.
+
+	<file name> is the name of the object file, <start> is the offset to the
+	code to trace in that file, and <size> is the size of the region to
+	trace. 'start' and 'stop' filters need not specify a <size>.
+
+	If no object file is specified then the kernel is assumed, in which case
+	the start address must be a current kernel memory address.
+
+	<start> can also be specified by providing the name of a symbol. If the
+	symbol name is not unique, it can be disambiguated by inserting #n where
+	'n' selects the n'th symbol in address order. Alternately #0, #g or #G
+	select only a global symbol. <size> can also be specified by providing
+	the name of a symbol, in which case the size is calculated to the end
+	of that symbol. For 'filter' and 'tracestop' filters, if <size> is
+	omitted and <start> is a symbol, then the size is calculated to the end
+	of that symbol.
+
+	If <size> is omitted and <start> is '*', then the start and size will
+	be calculated from the first and last symbols, i.e. to trace the whole
+	file.
+
+	If symbol names (or '*') are provided, they must be surrounded by white
+	space.
+
+	The filter passed to the kernel is not necessarily the same as entered.
+	To see the filter that is passed, use the -v option.
+
+	The kernel may not be able to configure a trace region if it is not
+	within a single mapping.  MMAP events (or /proc/<pid>/maps) can be
+	examined to determine if that is a possibility.
+
+	Multiple filters can be separated with space or comma.

 The quipper C++ parser is available at

+https://chromium.googlesource.com/chromiumos/platform2
+
+It is under the chromiumos-wide-profiling/ subdirectory. This library can

 Unfortunately this parser tends to be many versions behind and may not be able
 to parse data files generated by recent perf.
