2018-06-07perf hists browser gtk: Use hist_entry__has_callchains()Arnaldo Carvalho de Melo
Since we can't go from struct hists to struct evsel for all cases (c2c is an exception) and we have access to the hist_entry, use hist_entry__has_callchains() in the GTK+ hists browser to figure out if callchains are available.

2018-06-06perf hists: Check if a hist_entry has callchains before using themArnaldo Carvalho de Melo
So far if we use 'perf record -g' this will make symbol_conf.use_callchain 'true' and logic will assume that all events have callchains enabled, but ever since we added the possibility of setting up callchains for some events (e.g.: -e cycles/call-graph=dwarf/) while not for others, we limit usage scenarios by looking at that symbol_conf.use_callchain global boolean, we better look at each event attributes. On the road to that we need to look if a hist_entry has callchains, that is, to go from hist_entry->hists to the evsel that contains it, to then look at evsel->sample_type for PERF_SAMPLE_CALLCHAIN. The next step is to add a symbol_conf.ignore_callchains global, to use in the places where what we really want to know is if callchains should be ignored, even if present. Then -g will mean just to select a callchain mode to be applied to all events not explicitely setting some other callchain mode, i.e. a default callchain mode, and --no-call-graph will set symbol_conf.ignore_callchains with that clear intention. That too will at some point become a per evsel thing, that tools can set for all or just a few of its evsels.

2018-04-27perf symbols: Unify symbol mapsArnaldo Carvalho de Melo
Remove the split of symbol tables for data (MAP__VARIABLE) and for functions (MAP__FUNCTION), its unneeded and there were various places doing two lookups to find a symbol, so simplify this. We still will consider only the symbols that matched the filters in place, i.e. see the (elf_(sec,sym)|symbol_type)__filter() routines in the patch, just so that we consider only the same symbols as before, to reduce the possibility of regressions. All the tests on 50-something build environments, in varios versions of lots of distros and cross build environments were performed without build regressions, as usual with all pull requests the other tests were also performed: 'perf test' and 'make -C tools/perf build-test'. Also this was done at a great granularity so that regressions can be bisected more easily.

2018-04-06perf hists browser: Remove leftover from row returned from refreshArnaldo Carvalho de Melo
The per-browser screen refresh routine (ui_browser->refresh()) should return the first row that should be cleaned after the rows just printed, in case not all rows available on the screen gets filled. When moving the extra title lines logic from the hists browser to the generic ui_browser class, one piece of that logic remained in the hists browser and then when going back from the annotate browser to the hists browser in a case where fewer lines were displayed in the hists browser, for instance when filtering the entries per substring, one line of the annotate browser would remain on the screen, fix that. Example of the screen artifact: ================================================================================ Samples: 73K of event 'cycles:ppp', 4000 Hz, Event count (approx.): 45172901394 Overhead Shared O Symbol 0.30% [kernel] [k] __indirect_thunk_start 0.09% [kernel] [k] __x86_indirect_thunk_r10 │ lfence ================================================================================ Here from 'perf top' the view was zoomed with '/thunk' to functions having that substring, then the first was annotated and from the annotate browser ESC was pressed, then the first lines were overwritten, but the 'lfence' line remained due to the off by one bug fixed in this cset.

2018-04-03perf ui browser: Move the extra title lines from the hists browserArnaldo Carvalho de Melo
This will be useful for the annotate browser as well, that wants to have extra title lines, i.e. the current ui_browser unconditionally reserves the first line for a browser title and the last one for status messages. But some browsers, like the buckets one (hists browser) needs extra lines to show headers, allowing it to be shown or not, press 'H' in 'perf top' or 'perf report' to see this feature. So move that logic to the core ui_browser used by the hists_browser ('perf top' and 'perf report' main interface) so that it can be used by the annotate browser too.
