perf ui/tui: Show fatal error message only if exists

2015-01-22T20:05:10Z

When perf exits with some error it shows the error message with ui__error() or ui__warning() and then calls ui__exit() during exit_browser(). On TUI, it then shows a window titled "Fatal Error" to inform user a last message which might be related with this condition. However it sometimes contains no message and just annoyes users. The usual case for this is running perf top as normal user. (And /proc/sys/kernel/perf_event_paranoid being 1).

perf ui/tui: Print backtrace symbols when segfault occurs

2014-12-23T15:05:59Z

The output will look like below. (I added an error into ui__init() for the test). $ perf report perf: Segmentation fault -------- backtrace -------- perf[0x503781] /usr/lib/libc.so.6(+0x33b20)[0x7f1a14f04b20] perf(ui__init+0xd5)[0x503645] perf(setup_browser+0x97)[0x4ce4e7] perf(cmd_report+0xcea)[0x4392ba] perf[0x428493] perf(main+0x60a)[0x427c0a] /usr/lib/libc.so.6(__libc_start_main+0xf0)[0x7f1a14ef1040] perf[0x427d29] [0x0] Signed-off-by: Namhyung Kim Cc: Adrian Hunter Cc: David Ahern Cc: Ingo Molnar Cc: Jiri Olsa Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/r/1419223455-4362-4-git-send-email-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf ui/tui: Protect windows by ui__lock

2013-12-26T14:22:01Z

Sometimes perf top TUI breaks display with concurrent help/input window and pr_* messages since they're not protected by ui__lock. You can check it by pressing (and not releasing) 'h' key on a "perf top -vvv" TUI session.

perf ui tui progress: Don't force a refresh during progress update

2013-11-11T18:56:39Z

Each call to tui_progress__update() would forcibly refresh the entire screen. This is somewhat inefficient and causes noticable flickering during the startup of perf-report, especially on large/slow terminals. It looks like the force-refresh in tui_progress__update() serves no purpose other than to clear the screen so that the progress bar of a previous operation does not subsume that of a subsequent operation. But we can do just that in a much more efficient manner by clearing only the region that a previous progress bar may have occupied before repainting the new progress bar. Then the force-refresh could be removed with no change in visuals. This patch disables the slow force-refresh in tui_progress__update() and instead calls SLsmg_fill_region() on the entire area that the progress bar may occupy before repainting it. This change makes the startup of perf-report much faster and appear much "smoother". It turns out that this was a big bottleneck in the startup speed of perf-report -- with this patch, perf-report starts up ~2x faster (1.1s vs 0.55s) on my machines. (These numbers were measured by running "time perf report" on an 8MB perf.data and pressing 'q' immediately.)

perf ui progress: Per progress bar state

2013-10-23T18:40:38Z

That will ease using a progress bar across multiple functions, like in the upcoming patches that will present a progress bar when collapsing histograms. Based on a previous patch by Namhyung Kim.

perf ui: Rename ui_progress to ui_progress_ops

2013-10-23T17:41:23Z

Reserving 'struct ui_progress' to the per progress instances, not to the particular set of operations used to implmenet a progress bar in the current UI (GTK, TUI, etc).

perf tools: Remove dependency on libnewt

2013-04-01T15:23:21Z

Now that the map browser shares the input routine with the hists browser, there is no need for using any libnewt routine, so remove all traces except for honouring NO_NEWT=1 on the makefile command line as an indication that TUI support is not needed, in fact it just sets NO_SLANG=1.
