Hello,
As we added data type profiling, 'perf mem report' should support that
as well. This patches just added a couple of convenient options.
$ perf mem report -T -s mem
# To display the perf.data header info, please use --header/--header-only options.
#
#
# Total Lost Samples: 0
#
# Samples: 131 of event 'cpu/mem-loads,ldlat=30/P'
# Total weight : 18561
# Sort order : mem,type
#
# Overhead Samples Memory access Data Type
# ........ ............ ....................................... .........

...
The code is also available at 'perf/mem-type-v1' branch in
git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git
Thanks,

Namhyung Kim (6):
perf hist: Correct hist_entry->mem_info refcounts
perf mem: Free the allocated sort string
perf mem: Rework command option handling
perf tools: Add mode argument to sort_help()
perf mem: Add -s/--sort option
perf mem: Add -T/--data-type option to report subcommand

Thanks for your review, I'll update the documentation. Namhyung
