When dealing with nested hist entries it's helpful to have a way to resort those nested objects. Adding optional callback call into output_resort function and following new interface function: typedef int (*hists__resort_cb_t)(struct hist_entry *he); void hists__output_resort_cb(struct hists *hists, struct ui_progress *prog, hists__resort_cb_t cb); Signed-off-by: NJiri Olsa <jolsa@kernel.org> Cc: David Ahern <dsahern@gmail.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1470074555-24889-7-git-send-email-jolsa@kernel.orgSigned-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>

When dynamic entries are used in the hierarchy mode with multiple events, the output might not be aligned properly. In the hierarchy mode, the each sort column is indented using total number of sort keys. So it keeps track of number of sort keys when adding them. However a dynamic sort key can be added more than once when multiple events have same field names. This results in unnecessarily long indentation in the output. For example perf kmem records following events: $ perf evlist --trace-fields -i perf.data.kmem kmem:kmalloc: trace_fields: call_site,ptr,bytes_req,bytes_alloc,gfp_flags kmem:kmalloc_node: trace_fields: call_site,ptr,bytes_req,bytes_alloc,gfp_flags,node kmem:kfree: trace_fields: call_site,ptr kmem:kmem_cache_alloc: trace_fields: call_site,ptr,bytes_req,bytes_alloc,gfp_flags kmem:kmem_cache_alloc_node: trace_fields: call_site,ptr,bytes_req,bytes_alloc,gfp_flags,node kmem:kmem_cache_free: trace_fields: call_site,ptr kmem:mm_page_alloc: trace_fields: page,order,gfp_flags,migratetype kmem:mm_page_free: trace_fields: page,order As you can see, many field names shared between kmem events. So adding 'ptr' dynamic sort key alone will set nr_sort_keys to 6. And this adds many unnecessary spaces between 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).

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.

Currently hists__collapse_resort() and hists__collapse_insert_entry() don't return an error code. Now that callchain_merge() can check for errors, abort and pass the error to the user. A later patch can add more work which also can fail.

Currently 'perf top --tui' decrements percentage of all entries on any key press. This is because it adds total period as new samples are added to hists. As perf-top does it currently but added samples are not passed to the display thread, the percentages are decresing continuously. So separate total period stat into a different variable so that it cannot affect the output total period. This new total period stats are used only for calcualating callchain percent limit.

We were doing column alignment in the format function for each cell, returning a string padded with spaces so that when the next column is printed the cursor is at its column alignment. This ends up needlessly printing trailing spaces, do it at the format iterator, that is where we know if it is needed, i.e. if there is more columns to be printed. This eliminates the need for triming lines when doing a dump using 'P' in the TUI browser and also produces far saner results with things like piping 'perf report' to 'less'. Right now only the formatters for sym->name and the 'locked' column (perf mem report), that are the ones that end up at the end of lines in the default 'perf report', 'perf top' and 'perf mem report' tools, the others will be done in a subsequent patch. In the end the 'width' parameter for the formatters now mean, in 'printf' terms, the 'precision', where before it was the field 'width'.

With the hist object having the perf_hpp_list we can now iterate sort format entries based in the hists object. Adding hists__for_each_sort_list macro to do that.
