Subject: [PATCHSET 0/5] perf tools: Add call-graph config options (v2)

Hello,

This is patchset to add new callchain related config options so that
users don't need to pass their preference to the cmdline everytime.

Following config options will be added, and users can set appropriate
values to ~/.perfconfig file.  Note that the dump-size option is
meaningful only if record-mode = dwarf.

  $ cat ~/.perfconfig
  [call-graph]
    record-mode = dwarf
    dump-size = 4096
    print-type = graph
    order = callee
    threshold = 0.5
    print-limit = 128
    sort-key = function

  $ perf record -vg sleep 1
  callchain: type DWARF
  callchain: stack dump size 4096
  mmap size 528384B
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.054 MB perf.data (~2378 samples) ]
  Looking at the vmlinux_path (7 entries long)
  Using /lib/modules/3.16.3-1-ARCH/build/vmlinux for symbols


Jiri and David, I kept your Acked-by and Reviewed-by in this version.
Please take a look at the patch 4/5 which splits parser functions that
it still looks okay to you.


changes in v2)
 * use sizeof("call-graph.") instead of hardcoding the length  (Jiri)
 * split parse functions so that only handle relavant options
 * add Acked/Reviewed-by tags from David and Jiri


You can also get this from 'perf/callchain-config-v2' branch on my tree

Any comments are welcomed, thanks
