perf report/top: Add --raw-trace option
The --raw-trace option allows disabling pretty printing by the event's
print_fmt or plugin. Besides that, each dynamic sort key now can
receive a 'raw' suffix separated by '/' to ask for the raw trace of a
specific field.
$ perf report -s comm,kmem:kmalloc.gfp_flags
...
# Overhead Command gfp_flags
# ........ ....... ...................
#
99.89% perf GFP_NOFS|GFP_ZERO
0.06% sleep GFP_KERNEL
0.03% perf GFP_KERNEL|GFP_ZERO
0.01% perf GFP_KERNEL
Now
$ perf report -s comm,kmem:kmalloc.gfp_flags --raw-trace
or
$ perf report -s comm,kmem:kmalloc.gfp_flags/raw
...
# Overhead Command gfp_flags
# ........ ....... ..........
#
99.89% perf 32848
0.06% sleep 208
0.03% perf 32976
0.01% perf 208
