Hi Jean,
Now it is able to detect [kernel.kallsyms] so it shows the symbol name,
but it is not able to resolve all other symbols on call graph,
# ./perf record -g -e kmem:kmalloc cal
#
# Samples: 38 of event 'kmem:kmalloc'
# Event count (approx.): 38
#
# Overhead Command Shared Object Symbol
# ........ ....... ................. ..........................
#
97.37% cal [kernel.kallsyms] [k] kmem_cache_alloc_trace

2.63% cal [kernel.kallsyms] [k] __kmalloc

--- __kmalloc
showing only addresses.
