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 Namhyung
