2011-03-01perf tui: Make ui__warning modalArnaldo Carvalho de Melo1-2/+5
By taking the ui__lock so that no other screen updates take place while waiting for the user. That was happening when handling an invalid --vmlinux parameter in 'perf top --tui', with the screen refresh routine repainting the screen and removing the warning window.

2010-11-27perf tools: Fix lost and unknown events handlingArnaldo Carvalho de Melo1-1/+15
Fix it by explaining what can be happening and giving the number of processed and lost events. Also holler if unknown events were found, that can be due to processing a perf.data file collected using a newer tool where newer events got added on reporting using an older perf tool, that or a bug, so ask for a report to be made. Works on both --tui and --stdio.

2010-08-19perf ui browser: Add routines to compactly specify exit keysArnaldo Carvalho de Melo1-3/+1
This makes the usual idiom for specifying a series of key codes to exit ui_browser__run() for specialized processing (search, annotate, etc) or plain exiting the browser more compact. It also abstracts away some more libnewt operations. At some point we'll also replace NEWT_KEY_foo with something that can be mapped to NEWT or, say, gtk.

2010-07-27perf ui: New hists tree widgetArnaldo Carvalho de Melo1-311/+661
The stock newt checkbox tree widget we were using was not really suitable for hist entry + callchain browsing. The problems with it were manifold: - We needed to traverse the whole hist_entry rb_tree to add each entry + callchains beforehand. - No control over the colors used for each row So a new tree widget, based mostly on slang, was written. It extends the ui_browser class already used for annotate to allow the user to fold/unfold branches in the callchains tree, using extra fields in the symbol_map class that is embedded in hist_entry and callchain_node instances to store the folding state and when changing this state calculates the number of rows that are produced when showing a particular hist_entry instance. This greatly speeds up browsing as we don't have to upfront touch all the entries and only calculate callchain related operations when some callchain branch is actually unfolded. The memory footprint is also reduced as the data structure is not duplicated, just some extra fields for controling callchain state and to simplify the process of seeking thru entries (nr_rows, row_offset) were added.

2010-07-27perf ui: Consider the refreshed dimensions in ui_browser__showArnaldo Carvalho de Melo1-2/+4

For that to happen we must delete the old form, that will take care of deleting the vertical scrollbar, etc, and then recreate them, with the new dimensions.

2010-05-14perf report: Report number of events, not samplesArnaldo Carvalho de Melo1-3/+5
Number of samples is meaningless after we switched to auto-freq, so report the number of events, i.e. not the sum of the different periods, but the number PERF_RECORD_SAMPLE emitted by the kernel. While doing this I noticed that naming "count" to the sum of all the event periods can be confusing, so rename it to .period, just like in struct sample.data, so that we become more consistent. This helps with the next step, that was to record in struct hist_entry the number of sample events for each instance, we need that because we use it to generate the number of events when applying filters to the tree of hist entries like it is being done in the TUI report browser.

2010-05-14perf hist: Clarify events_stats fields usageArnaldo Carvalho de Melo1-3/+3
The events_stats.total field is too generic, rename it to .total_period, and also add a comment explaining that it is the sum of all the .period fields in samples, that is needed because we use auto-freq to avoid sampling artifacts. Ditto for events_stats.lost, that is the sum of all lost_event.lost fields, i.e. the number of events the kernel dropped. Looking at the users, builtin-sched.c can make use of these fields and stop doing it again.

2010-05-11perf report: Librarize the annotation code and use it in the newt browserArnaldo Carvalho de Melo1-46/+306
Now we don't anymore use popen to run 'perf annotate' for the selected symbol, instead we collect per address samplings when processing samples in 'perf report' if we're using the newt browser, then we use this data directly to do annotation. Done this way we can actually traverse the objdump_line objects directly, matching the addresses to the collected samples and colouring them appropriately using lower level slang routines. The new ui_browser class will be reused for the main, callchain aware, histogram browser, when it will be made generic and don't assume that the objects are always instances of the objdump_line class maintained using list_heads.

2010-05-11perf ui: Add ui_helpline methodsArnaldo Carvalho de Melo1-19/+50
Initially this was just to be able to have a printf like method to prepare the formatted string and then pass to newtPushHelpLine, but as we already have for ui_progress, etc, its a step in identifying a restricted, highlevel set of widgets we can then have implementations for multiple widget sets (GTK, etc).

2010-05-11perf hist: Adopt filter by dso and by thread methods from the newt browserArnaldo Carvalho de Melo1-66/+14
Those are really not specific to the newt code, can be used by other UI frontends.
