perf tools: Add sort__has_comm variable

2016-03-10T19:47:19+00:00

The sort__has_comm variable is to check whether the comm sort key is given. This is necessary to support thread filtering in the TUI hists browser later.

perf tools: Remove hist_entry->fmt field

2016-03-10T19:45:59+00:00

It's not used anymore and the output format is accessed by the hpp_list pointer instead when hierarchy is enabled. Let's get rid of it.

perf hists: Use own hpp_list for hierarchy mode

2016-03-08T09:11:19+00:00

Now each hists has its own hpp lists in hierarchy. So instead of having a pointer to a single perf_hpp_fmt in a hist entry, make it point the hpp_list for its level. This will be used to support multiple sort keys in a single hierarchy level.

perf hists browser: Show message for percent limit

2016-02-26T14:20:36+00:00

Like the stdio, it should show messages about omitted hierarchy entries. Please refer the previous commit for more details. As it needs to check an entry is omitted or not multiple times, add the has_no_entry field in the hist entry.

perf hists: Introduce hist_entry__filter()

2016-02-24T23:19:14+00:00

The hist_entry__filter() function is to filter hist entries using sort key related info. This is needed to support hierarchy mode since each hist entry will be associated with a hpp fmt which has a sort key. So each entry should compare to only matching type of filters. To do that, add the ->se_filter callback field to struct sort_entry. This callback takes 'type' argument which determines whether it's matching sort key or not. It returns -1 for non-matching type, 0 for filtered entry and 1 for not filtered entries.

perf hists: Basic support of hierarchical report view

2016-02-24T16:35:44+00:00

In the hierarchical view, entries will be grouped and sorted on the first key, and then on the second key, and so on. Add the he->hroot_{in,out} fields to keep the lower level entries. Actually this can share space, in a union, with callchain's 'sorted_root' since the hroots are only used by non-leaf entries and callchain is only used by leaf entries. It also adds the 'parent_he' and 'depth' fields which can be used by browsers. This patch only implements collapsing part which creates internal entries for each sort key. These need to be sorted by output_sort stage and to be displayed properly in the later patch(es).

perf hists browser: Offer 'Zoom into DSO'/'Map details' only when sort order has 'dso'

2016-01-26T14:52:50+00:00

We can't offer a zoom into DSO when a bucket (struct hist_entry) may have samples for more than one DSO, i.e. when 'dso' is not part of the sort order, ditto for 'Map details', fix it.

perf sort: Provide a way to find out if per-thread bucketing is in place

2016-01-26T14:52:49+00:00

Now the UI browsers will be able to offer thread related operations only if the thread is part of the sort order in use, i.e. if hist_entry stats are all for a single thread.
