2016-02-03perf hists: Introduce hists__for_each_format macroJiri Olsa
With the hist object having the perf_hpp_list we can now iterate output format entries based in the hists object. Adding hists__for_each_format macro to do that.

2016-02-01perf hists browser: Fix percent display in callchainsNamhyung Kim
When there's only a single callchain, perf doesn't print its percentage in front of the symbols. This is because it assumes that the percentage is same as parents. But if a percent limit is applied, it's possible that there are actually a couple of child nodes but only one of them is shown. In this case it should display the percent to prevent misunderstanding of its percentage is same as the parent's. For example, let's see the following callchain. $ perf report --no-children --percent-limit 0.01 --tui ... - 0.06% sleep [kernel.vmlinux] [k] kmem_cache_alloc_trace kmem_cache_alloc_trace - perf_event_mmap - 0.04% mmap_region do_mmap_pgoff - vm_mmap_pgoff + 0.02% sys_mmap_pgoff + 0.02% vm_mmap + 0.02% mprotect_fixup Current code omits the percent if 'mmap_region' becomes the only node when percent limit is set to 0.03%, its percent is not 0.06% but users will assume it incorrectly. Before: $ perf report --no-children --percent-limit 0.03 --tui ... 0.06% sleep [kernel.vmlinux] [k] kmem_cache_alloc_trace kmem_cache_alloc_trace - perf_event_mmap - mmap_region do_mmap_pgoff vm_mmap_pgoff After: $ perf report --no-children --percent-limit 0.03 --tui ... 0.06% sleep [kernel.vmlinux] [k] kmem_cache_alloc_trace kmem_cache_alloc_trace - perf_event_mmap - 0.04% mmap_region do_mmap_pgoff vm_mmap_pgoff Signed-off-by: Namhyung Kim <namhyung@kernel.org> Cc: Andi Kleen <andi@firstfloor.org> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/r/1453909257-26015-10-git-send-email-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

When there's only a single callchain, perf doesn't print its percentage in front of the symbols. This is because it assumes that the percentage is same as parents. But if a percent limit is applied, it's possible that there are actually a couple of child nodes but only one of them is shown.

2016-01-08perf tools: Add overhead/overhead_children keys defaults via stringJiri Olsa
We currently set 'overhead' and 'overhead_children' as default sort keys within perf_hpp__init function by directly adding into the sort list. This patch adds 'overhead' and 'overhead_children' in text form into sort_keys and let them be added by standard sort dimension interface. We need to eliminate dirrect sort_list additions to be able to add support for hists specific sort keys.

2015-12-09perf tui: Change default selection background color to yellowIngo Molnar
Boris reported that 'perf top' is unusable on his default 'black on white' terminal, which uses (eye friendly) light-grey as a background color. The reason is that the TUI cursor for the current selection line uses HE_COLORSET_SELECTED, and that has a default background color of 'lightgrey' - which is a common terminal background choice and thus the colors conflict. Use yellow as the background color instead: that should be an uncommon terminal background, yet it's still ergonomic on both black and white/grey terminals. [ It would be a better solution to straight out detect color collisions and resolve them reasonably by converting them to RGB and calculating color space distances, but I was unable to find proper documentation for SLtt_get_color_object() to recover the current color scheme so I gave up ...

2015-12-07perf hists browser: Reset selection when refreshWang Nan
With the following steps: Step 1: perf report Step 2: Use UP/DOWN to select an entry, don't press 'ENTER' Step 3: Use '/' to filter symbols, use a filter which returns empty result Step 4: Press 'ENTER' We see that, even if we have filtered all the symbols (and the main interface is empty), pressing 'ENTER' still selects one symbol. This behavior surprises the user. This patch resets browser->{he_,}selection in hist_browser__refresh() and lets it choose default selection. In this case browser->{he_,}selection keeps NULL so user won't see annotation item in menu.

2015-11-27perf hists browser: Update nr entries regardless of min percentNamhyung Kim
When perf report on TUI was called with -S symbol filter, it should update nr entries even if min_pcnt is 0. IIRC the reason was to update nr entries after applying minimum percent threshold. But if symbol filter was given on command line (with -S option), it should use hists->nr_non_filtered_entries instead of hists->nr_entries. So this patch fixes a bug of navigating hists browser that the cursor goes beyond the number of entries when -S (or similar) option is used.
