I used the following command to trace the kernel on the i.MX8MM board.

$ trace-cmd record -p function_graph ls

$ trace-cmd report

but I saw the following result just show the address instead of the function name.

MtpServer-4877 [000] 1704.714272: funcgraph_exit: ! 110.375 us | }
MtpServer-4877 [000] 1704.714274: funcgraph_entry: 1.375 us | ffff0000082e37f8();

MtpServer-4877 [000] 1704.714329: funcgraph_exit: + 21.250 us | }

May I know how to show the exact function name on the trace-cmd result?
