	--pid		# include PID with process names [1]
	--tid		# include TID and PID with process names [1]
	--inline	# un-inline using addr2line
	--all		# all annotations (--kernel --jit)
	--kernel	# annotate kernel functions with a _[k]
	--jit		# annotate jit functions with a _[j]
	--context	# adds source context to --inline
	--addrs		# include raw addresses where symbols can't be found
	--event-filter=EVENT	# event name filter

[1] perf script must emit both PID and TIDs for these to work; eg, Linux < 4.1:
	perf script -f comm,pid,tid,cpu,time,event,ip,sym,dso,trace
    for Linux >= 4.1:
	perf script -F comm,pid,tid,cpu,time,event,ip,sym,dso,trace
    If you save this output add --header on Linux >= 3.14 to include perf info.
