vindexive built a vanilla 3.2.10 kernel with perf enabled, since i wnated to use the performance counters for a personal project02:36
vindexwith make-kpkg i get the different deb packages, however the perf tool consistently fails the symbol test02:37
vindexif i boot the same kernel with qemu and into a debian/ubuntu qemu image, the perf tool works fine02:37
vindexcan the linux-tools packages get built through make-kpkg as well?03:43

* apw yawns ... another 80MB of updates08:15
ppisatimoin08:16
apwppisati, morning08:17
smbmorning... lots of fun to look forward to08:18
apwsmb, a shiney new unity ... i wonder what fun that brings ... any guess where the keys are today08:22
* smb needs to install the shiny thing to know...08:22
* apw watches it install ... excitemente08:24
smbapw, At least nothing gets removed... I think I saw in the upload mails that this will be famous 5.6 we have all been waiting for... 08:24
apwyeah what did 5.6 contains that we needed ?  was that the alt not being annoying one ?08:25
* ppisati loves the smell of apw's positivty wrt to unity in the morning :)08:26
smbapw, yes I think so (or generally the "even without multitouch you can press two keys at once, now stop giving me the help screen on super+something"08:27
apwnew flash it seems in the bargain08:28
amitkapw: hehe. Over on this side of the fence, work has ground to halt as everyone upgrades the galaxy s2 phones to Android 4.x and deals with the consequences :)08:28
apwheheh ... that sounds fun08:28
* ppisati -> reboot08:29
apw    - Dash - update Dash keyboard shortcuts so the 'CTRL + TAB' switches08:29
apw      between Lenses and 'TAB' by itself moves the focus between categories08:29
apwnew keybindings ...08:29
apw    - Alt+Tab default delay of 150ms is too long (LP: #888636)08:30
apw    - Numbers on Launcher icons sticking (LP: #942359)08:31
ppisatiso far, so good08:31
* apw reboots to get the new shiney08:31
* smb wonders whether you need fps experience to have the reflexes required to operate it...08:32
ppisatiunity2d: works here, still no overlay shortcut text and (thanks God) still no launcher on the second screen (with that bloody sticky edge)08:37
* smb ready to do the same (reboot)08:38
apwwell i was able to reboot and login ...08:42
apwglad to see they havent fixed the help 08:43
smbat least it does not come up when you press super+alt...08:44
ppisatibtw, did you see that the unity/UX/usability/$something_team is running a poll about multi screen setup + multi launcher setup?08:45
apwppisati, nope, where is that as i want to be chosing08:45
ppisatiyou can even vote AGAINST sticky edge on the second screen and multi panel setup08:45
ppisatihold on08:45
ppisatinope08:46
apwppisati, though asking me to chose when i can only try one of them is a bit daft08:46
ppisatiactually the poll is "omg ubuntu" made for the unity team08:46
ppisatibig cockup... :P08:46
apwoh so that won't have any input then08:47
ppisatiyep :(08:47
* ppisati curls in sadness in a corner, you can't stop the sticky screeny edge, they will assimilate us...08:48
apwheheh08:48
smbHm, still got the issue that clicking on an existing app in launcher moves the app and not the viewport... :/08:48
smbat least for some of them08:48
apwsmb, i still get launcher and help on pressing super-alt together if super is the first key that closes ... however short a time08:48
smbapw, Yes, true. same here08:56
* apw also notes the resize space round a window has stopped working so you have to hit the 1px again08:57
jk-alt+right drag?08:58
smbapw, hm there seems to be some space to left and bottom at least08:58
apwjk-, oh i know how to get round it, but i doubt its expected to have gone08:58
apwsmb, not for me08:59
smbto the right as well if only that stupid hidden scrollbar would not be08:59
smbtop is only 1px...09:00
apwnot any side for me, i have 1px and 1px only everywhere09:00
smbapw, the special apw settings ...?09:00
apwperhaps so .. sigh09:00
smbapw, Or maybe... is that on a external screen?09:01
apwnope all of 'em09:02
smbJust was wondering whether the issue rises because there is more than one screen, which I do not have09:04
* apw doesn't really care ... i have it ... and so a bug i will file09:07
smbGiven the speed of updates one feels like the white rabbit... I am too late for updates... I am too late for updates...09:08

apwmention the bug on #ubuntu-unity09:50
smb`apw, Since you said you do not use multiple desktops that much, you would less likely. And it does not seem to happen with all applications09:50
apwoh dear thats most odd, oh yeah and i would have to start using them to hit it09:51
apwppisati, in your precise/ti-omap4 rebase i see two commits i am not expecting ... right at the bottom of your delta ... 10:24

apwppisati, i am not expecting either of those to be in your delta10:25
apwppisati, if you concur i can just rebase them out of existance10:25

apwsudo aa-disable sbin.dhclient10:41
ppisatiapw: go ahead with those two commits, seems i rebased on master 10:46

apwumount and inotify ... hmm ... that rings a bell, i wonder if there was someting committed to linus recently15:44
apwhenrix, ahh did you add a keyboard since mumble started, that can break PPT keys15:45

smbapw, The trigger may be hard. Though the queue is applicable when the review starts16:36

ah-hi, i'm playing with kernel development on ubuntu and i'm wondering what's the best way to do incremental compiles19:53
ah-at the moment i'm compiling my kernel according to http://blog.avirtualhome.com/2011/10/28/how-to-compile-a-new-ubuntu-11-10-oneiric-kernel/ and https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel19:54
ah-my problem with that is that after i change something "skipabi=true skipmodule=true fakeroot debian/rules binary-mbp" doesn't include my changes if i don't do "fakeroot debian/rules clean"19:55
ah-before19:55
ah-but cleaning and doing a full build on every change takes a lot of time19:55
pbuckleydistcc is your friend19:55
ah-so it's not possible to do incremental builds?19:57
ah-i fear even with distcc/ccache it'll take ages19:57
pbuckleyi prefer to do full builds.. i think of it as safer20:04
pbuckleyi think if you do the plain old make20:05
pbuckleyyou can do incremetal builds20:05
ohsixif you're working on a module you can use the regular linux build stuff to test it20:05
