see vdso function with perf report

On my perf report I see a bunch of lines with vdso modules and no function names. I am guessing these are for gettimeofday type calls. But how can I see actual function calls? My perf record command:

-shell
sudo perf record -a -g -k 1 --call-graph dwarf,16384 -F 99 -e cpu-clock:pppH -p $PID -- sleep 60

and using sudo perf report to view the report. It shows something like:

+    2.83%     0.00%  myprog  [vdso]              [.] 0x00007fff983f6738

I am on kernel version 5.10 using Amazon Linux 2.
