perf hists browser: The dso can be obtained from popup_action->ms.map->dso

2015-11-12T21:58:18+00:00

So no need to have a 'dso' member in 'popup_action', remove it as no code is using it, already. Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Namhyung Kim Cc: Wang Nan Link: http://lkml.kernel.org/n/tip-76a6s0007slug0op0wkl6o8b@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf hists browser: Fix 'd' hotkey action to filter by DSO

2015-11-12T21:58:17+00:00

When pressing 'd' the expected action is to filter all entries by the DSO in the current entry, but for that the action->map needs to be set, and only action->dso was being set, fix it.

perf annotate: Don't die() when finding an invalid config option

2015-10-22T21:10:52+00:00

The perf_config() infrastructure we inherited from git calls die() when the provided config callback returns -1, meaning some key in a config section is unexpected, that seems ok for a stdio based tool, but in --tui we end up messing up the output, so just tell the user about the error, wait for a keystroke and return 0, being more resilient and proceeding with what we managed to parse. That die() needs to die, tho :-) Cc: Adrian Hunter Cc: Borislav Petkov Cc: David Ahern Cc: Frederic Weisbecker Cc: Jiri Olsa Cc: Namhyung Kim Cc: Stephane Eranian Cc: Wang Nan Link: http://lkml.kernel.org/n/tip-pqtsffh2kwr5mwm4qg9kgotu@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf annotate: Fix 'annotate.use_offset' config variable usage

2015-10-22T19:34:29+00:00

The annotate__configs should be sorted so that it can use bsearch(3). However commit 0c4a5bcea460 ("perf annotate: Display total number of samples with --show-total-period") added a new config item at the end. This resulted in the 'annotate.use_offset' config variable cannot be found and perf terminated like below: $ perf report bad config file line 6 in ~/.perfconfig Signed-off-by: Namhyung Kim Cc: David Ahern Cc: Jiri Olsa Cc: Martin Liška Cc: Peter Zijlstra Cc: Taeung Song Fixes: 0c4a5bcea460 ("perf annotate: Display total number of samples with --show-total-period") Link: http://lkml.kernel.org/r/1445396240-3428-1-git-send-email-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf hists browser: Add 'm' key for context menu display

2015-10-13T02:29:14+00:00

With horizontal scrolling, the left/right arrow keys are used to scroll columns and ENTER/ESC keys are used to enter/exit menu. However if callchain is recorded, the ENTER key is used to toggle callchain expansion so there's no way to display menu. Use 'm' key to display the menu for this case.

perf hists browser: Inform how to reset the symbol filter

2015-10-12T17:02:29+00:00

When in the hists browser, i.e. in 'perf report' or in 'perf top', it is possible to press '/' and specify a substring to filter by symbol name. Clarify how to remove a filter by making the prompt be: Please enter the name of symbol you want to see. To remove the filter later, press / + ENTER Cc: Adrian Hunter Cc: Borislav Petkov Cc: David Ahern Cc: Frederic Weisbecker Cc: Jiri Olsa Cc: Namhyung Kim Cc: Stephane Eranian Cc: Wang Nan Link: http://lkml.kernel.org/n/tip-vbq2b0kyufwy6p0ctkfswcoe@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf ui browsers: Remove help messages about use of right and arrow keys

2015-10-12T16:56:50+00:00

They were repurposed for horizontal scrolling, so use just ENTER/ESC in the help messages.

perf hists browser: Implement horizontal scrolling

2015-10-05T20:59:49+00:00

Do it using the recently introduced ui_brower scrolling mode, setting ui_browser.columns to the number of sort columns and then, when rendering each line, skipping as many initial columns as the user pressed the right arrow. As the user presses the left arrow, the ui_browser code will remove the scrolling counter and the left scrolling takes place. The right arrow key was an alias for ENTER, so people used to press it may get a bit annoyed at first, sorry! Ditto for ESC and the left key. Callchains can be left as is or we can, when rendering the Symbol column, store the at what position on the screen it is and then using ui_browser__gotorc() to print it from there, i.e. the callchain would move around with the symbol. Leaving it as is, i.e. at a fixed position, close to the left, saves precious screen real state for it, so I'm inclined to leave it as is now.

perf hists browser: Use the map to determine if a DSO is being used as a kernel

2015-09-28T18:50:54+00:00

The map is what should say if an ELF (or some other format) image is being used for some particular purpose, as a kernel, host or guest.
