perf hists: Move sort__has_sym into struct perf_hpp_list

2016-05-06T00:03:59+00:00

Now we have sort dimensions private for struct hists, we need to make dimension booleans hists specific as well. Moving sort__has_sym into struct perf_hpp_list.

perf tools: Remove nr_sort_keys field

2016-03-10T19:46:08+00:00

The nr_sort_keys field is to carry the number of sort entries in a hpp_list or hists to determine the depth of indentation of a hist entry. As it's only used in hierarchy mode and now we have used nr_hpp_node for this reason, there's no need to keep it anymore. Let's get rid of it.

perf hists: Fix indent for multiple hierarchy sort key

2016-03-08T09:11:20+00:00

When multiple sort keys are used in a single hierarchy, it should indent using number of hierarchy levels instead of number of sort keys.

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: Introduce perf_hpp__setup_hists_formats()

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

The perf_hpp__setup_hists_formats() is to build hists-specific output formats (and sort keys). Currently it's only used in order to build the output format in a hierarchy with same sort keys, but it could be used with different sort keys in non-hierarchy mode later.

perf hists: Add more helper functions for the hierarchy mode

2016-02-26T14:20:35+00:00

The hists__overhead_width() is to calculate width occupied by the overhead (and others) columns before the sort columns. The hist_entry__has_hiearchy_children() is to check whether an entry has lower entries (children) in the hierarchy to be shown in the output. This means the children should not be filtered out and above the percent limit. These two functions will be used to show information when all children of an entry is omitted by the percent limit (or filter).

perf tools: Fix assertion failure on dynamic entry

2016-02-22T15:07:14+00:00

The dynamic entry is created for each field in a tracepoint event. Since they have no fixed hpp format index, it should skip when perf_hpp__reset_width() is called. This caused following assertion failure.. $ perf record -e sched:sched_switch -a sleep 1 $ perf report -s comm,next_pid --stdio perf: ui/hist.c:651: perf_hpp__reset_width: Assertion `!(fmt->idx >= PERF_HPP__MAX_INDEX)' failed.

perf hists: Introduce hists__for_each_format macro

2016-02-03T15:24:19+00:00

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.

perf hists: Add struct perf_hpp_list argument to helper functions

2016-02-03T15:24:17+00:00

Adding struct perf_hpp_list argument to following helper functions: void perf_hpp__setup_output_field(struct perf_hpp_list *list); void perf_hpp__reset_output_field(struct perf_hpp_list *list); void perf_hpp__append_sort_keys(struct perf_hpp_list *list); so they could be used on hists's hpp_list.
