perf tools: Skip dynamic fields not defined for current event

2016-01-06T23:11:12Z

When there are multiple events, each dynamic sort key is defined just for one event. In this case other events will always show "N/A" for those fields. But they are meaningless and consume precious screen width. Let's skip those undefined dynamic fields. $ perf record -e kmem:kmalloc,kmem:kfree -a sleep 1 $ perf report -s 'comm,kmalloc.*' --stdio # To display the perf.data header info, please use --header/--header-only options. # # # Total Lost Samples: 0 # # Samples: 20K of event 'kmem:kmalloc' # Event count (approx.): 20533 # # Overhead Command call_site ptr bytes_req bytes_alloc gfp_flags # ........ ....... .................. .................. ......... ........... ................... # 99.89% perf ffffffffa01d4396 0xffff8803ffb79720 96 96 GFP_NOFS|GFP_ZERO 0.06% sleep ffffffff8114e1cd 0xffff8803d228a000 4096 4096 GFP_KERNEL 0.03% perf ffffffff811d6ae6 0xffff8803f7678f00 240 256 GFP_KERNEL|GFP_ZERO 0.00% perf ffffffff812263c1 0xffff880406172380 128 128 GFP_KERNEL 0.00% perf ffffffff812264b9 0xffff8803ffac1600 504 512 GFP_KERNEL 0.00% perf ffffffff81226634 0xffff880401dc5280 28 32 GFP_KERNEL 0.00% sleep ffffffff81226da9 0xffff8803ffac3a00 392 512 GFP_KERNEL # Samples: 20K of event 'kmem:kfree' # Event count (approx.): 20597 # # Overhead Command # ........ .............. # 99.63% perf 0.14% sleep 0.11% irq/36-iwlwifi 0.11% kworker/u16:0 0.01% Xorg 0.00% firefox Signed-off-by: Namhyung Kim Acked-by: Jiri Olsa Tested-by: Arnaldo Carvalho de Melo Cc: Andi Kleen Cc: David Ahern Cc: Frederic Weisbecker Cc: Peter Zijlstra Cc: Steven Rostedt Cc: Wang Nan Link: http://lkml.kernel.org/r/1450804030-29193-12-git-send-email-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf ui/gtk: Support folded callchains

2015-11-19T16:19:26Z

The folded callchain mode is to print all chains in a single line. Currently perf report --gtk doesn't support folded callchains. Like flat callchains, only leaf nodes are added to the final rbtree so it should show entries in parent nodes.

perf ui/gtk: Support flat callchains

2015-11-19T16:19:25Z

The flat callchain mode is to print all chains in a simple flat hierarchy so make it easy to see. Currently perf report --gtk doesn't show flat callchains properly. With flat callchains, only leaf nodes are added to the final rbtree so it should show entries in parent nodes. To do that, add parent_val list to struct callchain_node and show them along with the (normal) val list. See the previous commit on TUI support for more information.

perf build: Add gtk objects building

2015-02-12T14:49:12Z

Move the gtk objects building under build framework. Add new gtk build object so it's separated from the rest of the code and could be librarized.

perf callchain: Use a common function to resolve symbol or name

2014-11-19T15:33:47Z

Refactor the duplicated code to resolve the symbol name or the address of a symbol into a single function. Used in next patch to add common functionality.

perf evsel: Add hists helper

2014-10-09T16:13:41Z

Not all tools need a hists instance per perf_evsel, so lets pave the way to remove evsel->hists while leaving a way to access the hists from a specially allocated evsel, one that comes with space at the end where lives the evsel.

perf tools: Add name field into perf_hpp_fmt

2014-08-12T15:03:07Z

It makes the code a bit simpler and easier to debug IMHO. I guess it can also remove similar code in perf diff, but let's keep it for a future work. :) Signed-off-by: Namhyung Kim Cc: Ingo Molnar Cc: Jiri Olsa Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1406785662-5534-7-git-send-email-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf report: Honor column width setting

Set column width and do not change it if user gives -w/--column-widths option. It'll truncate longer symbols than the width if exists.

perf tools: Make hppfmt() receive an additional len argument

2014-08-12T15:03:05Z

So that it can properly handle alignment requirements later. To do that, add percent_color_len_snprintf() fucntion to help coloring of overhead columns.
