Are you suggesting using mfd_add_devices()? At first glance it looks
like that

Add top.children config option for setting default value of
callchain accumulation. It affects the output only if one of
-g or --call-graph option is given as well.
A user can write .perfconfig file like below to enable accumulation
by default:
$ cat ~/.perfconfig
[top]
children = true
The cpumode and level in struct addr_localtion was set for a sample
and but updated as cumulative callchains were added. This led to have
non-matching symbol and cpumode in the output.
Update it accordingly based on the fact whether the map is a part of
the kernel or not. This is a reverse of
The fill_callchain_info() will be shared with perf top --children.
