| jaeger | thanks for taking some time to look at it, I'll keep digging | 00:03 |
|---|---|---|
| tilman | maybe you should first use a profiler and see where the process is spending its cycles | 00:03 |
| tilman | cd $kernelsrc/tools/perf && make | 00:04 |
| tilman | and get a debug build for gnome-shell | 00:04 |
| jaeger | hrmm... wonder if that's something I'll actually understand :D I guess it can't hurt to try | 00:05 |
| tilman | (CFLAGS="-O0 -g", configure --enable-debug as a random guess, then pkgmk -ns -kw | 00:05 |
| tilman | _then_ tweak your wrapper script to run: | 00:05 |
| tilman | perf record /usr/bin/gnome-shell | 00:05 |
| jaeger | Does the kernel's profiling support need to be enabled or is that only for profiling the kernel itself? | 00:06 |
| tilman | the latter | 00:06 |
| jaeger | ok | 00:06 |
| tilman | running the shell for ~30s should suffice | 00:06 |
| tilman | afterwards you can "perf report" to see what's up | 00:06 |
| jaeger | thanks, I'll try that. Should be an interesting learning experience | 00:06 |
| tilman | let me know if you need a little hand holding =) | 00:07 |
| tilman | gonna crash now | 00:07 |
| jaeger | will do, thanks! | 00:07 |
| jaeger | take care | 00:07 |

| xvee | hello everyone | 07:59 |
| joacim | hey xvee | 08:36 |
| joacim | you asked to see some of my stuff a few days ago | 08:36 |
| joacim | still interested? | 08:36 |
| nwe | good morning | 08:42 |
| joacim | morning =) | 08:42 |
| nwe | how are you guys? | 08:42 |
| joacim | doing fine. a bit tired | 08:42 |
| joacim | and you | 08:42 |
| joacim | ? | 08:42 |
| nwe | im fine, I have just eating some breakfast.. | 08:43 |
| nwe | brb | 08:43 |
| joacim | xvee: http://cl.ly/TBiR <- this contains gnome-mplayer and gmtk, but not gecko-mediaplayer | 08:44 |
| joacim | I never made one for gecko-mediaplayer since I was trying to use webkit based browsers at the time, and it seemed like gecko-mediaplayer wanted gecko/firefox to build | 08:45 |
| xvee | joacim: i want gecko-mediaplayer to get youtube to work | 08:57 |
| xvee | i found this nifty little tool that forces html5 to play, but for some reason, wont without gecko-mediaplayer | 08:58 |
| xvee | im trying to go as open source as possible, but flash is the only thing left thats really holding me back | 08:58 |
| joacim | gecko-mediaplayer depends on gmtk anyways | 08:58 |
| joacim | which my tarball contains | 08:59 |
| xvee | are you on chrome or firefox by any chance? | 08:59 |
| joacim | safari | 08:59 |
| xvee | oh yea, you have a mac | 08:59 |
| xvee | bah | 08:59 |

| jaeger | tilman: any known side effects of enabling that? | 14:35 |
| jaeger | tilman: I left perf report running overnight and it hasn't printed anything :/ | 14:36 |
| tilman | jaeger: not that i know of | 14:37 |
| tilman | perf report is just the user interface; it should show stuff instantly | 14:37 |
| jaeger | that's kinda what I figured | 14:37 |
| tilman | try "perf record less randomreadme" to learn how it works | 14:38 |
| tilman | it will write the results file (perf.data by default, iirc) once the child process (here: less) exits | 14:38 |
| jaeger | perhaps I'm missing some lib it needs to display | 14:38 |
| jaeger | It did create perf.data | 14:38 |
| *** acrux has joined #crux | 14:38 | |
| tilman | jaeger: does it work with a trivial test case? | 14:47 |
| jaeger | don't know yet, was trying to recompile it with TUI support. I'll test the trivial case first, makes more sense | 14:52 |
| tilman | TUI not needed | 14:52 |
| tilman | i like the basic interface better even | 14:52 |
| jaeger | Ah, ok. Yeah, it worked fine, seems like | 14:53 |
| jaeger | instant output | 14:53 |
| tilman | how large is the perf.data from gnome-shell? | 14:53 |
| jaeger | 5M | 14:54 |
| jaeger | vs. 232K for the less test | 14:54 |
| tilman | should be fine | 14:54 |
| tilman | care to upload the 5M one? | 14:55 |
| jaeger | sure | 14:55 |
| jaeger | http://jaeger.morpheus.net/misc/perf.data.xz | 14:56 |
| tilman | 403 | 14:56 |
| jaeger | grrr, fuckin' scp | 14:56 |
| jaeger | fixed | 14:56 |
| tilman | ._o | 14:57 |
| tilman | i've never seen that before | 14:57 |
| jaeger | figures. :( | 14:57 |
| jaeger | same result for you? | 14:57 |
| tilman | it just sits there for me as well | 14:57 |
| tilman | yes | 14:57 |
| jaeger | I'll try generating a new one | 14:57 |
| tilman | there's another thing you can try | 14:58 |
| tilman | ignore the perf record stuff; just run gnome-shell | 14:58 |
| tilman | and then run "perf top" | 14:58 |
| tilman | that might give some clues to the problem itself | 14:59 |
| jaeger | ok | 14:59 |
| jaeger | interesting indeed. libglib-2.0.so.0.3800.2 jumps to the top of the list | 15:00 |
| jaeger | with [kernel] and libpthread-2.16.so behind it | 15:01 |
| tilman | you're interested in the names of the functions in gnome-shell that are at the top | 15:01 |
| tilman | you should be able to zoom into gnome-shell | 15:01 |
| prologic | got a port for the android-sdk-platform-tools in my repo if anyone's interested | 15:01 |
| jaeger | gnome-shell isn't even listed... am I invoking perf top wrong? | 15:02 |
| jaeger | it just shows a bunch of libraries and a few processes. htop, bash, perf, Xorg | 15:02 |
| jaeger | I rebuilt gnome-shell with CFLAGS set to -O0 -g but it doesn't support --enable-debug in its configure script. I also did not strip it | 15:03 |
| tilman | that should be fine :| | 15:05 |
| jaeger | libgnome-shell.so popped up in the list but it's 0.00% | 15:06 |
| jaeger | my perf top output doesn't look like what the perf wiki shows, wonder why | 15:08 |
| tilman | i'm pretty sure the wiki is outdated | 15:08 |
| jaeger | http://imgur.com/L6HlxAO <-- there's what it's displaying | 15:10 |
| tilman | hum | 15:15 |
| jaeger | It complains that it can't find a vmlinux file so kernel samples won't be resolved, is that the problem here? | 15:15 |
| tilman | nope, since you're not interested in the kernel | 15:16 |
| tilman | we only care about userspace processes | 15:16 |
| jaeger | ok | 15:16 |
| jaeger | dso: gnome-shell.orig (/usr/bin/gnome-shell.orig, Functions, NOT loaded, 0000000000000000000000000000000000000000) | 15:22 |
| *** dkoby has quit IRC | 15:24 | |
| jaeger | also interesting: results are different when running perf record as root and via sudo | 15:31 |
| jaeger | good to know | 15:31 |
| jaeger | well, slightly different. still not much info | 15:32 |
