smbRAOF, You still around? Who would be the guy caring about llvm-pipe/xserver-modeset these days? 08:44

RAOFsmb: You're probably after mlankhorst, mostly.09:33
smbRAOF, Ah, ok. Thanks. I am always unsure there...09:34
RAOFAlso tjaalton and Sarvatt can still be of assistance, probably :)09:36
RAOFWell, and me, depending on the question :)09:37
smbRAOF, I put it out on #ubuntu-desktop09:37
smbRAOF, Basically gnome term in virtual machines is not a happy bunny09:38
tjaaltonI'll check out what it looks like here..09:39
tjaaltonoops, need to migrate the images somewhere other than btrfs..09:40
smbtjaalton, The key piece (if you where responding to my question kinda) is to have a kvm or xen guest using the default cirrus graphics09:43
tjaaltonthe default is wrong imo09:44
tjaaltoniirc09:44
smbtjaalton, It is the historical default and its that (or potentially svga) that you get with xen09:45
smbtjaalton, I know some people like to push for vmvga but that is only available for kvm. And it is usually not working in different ways. Last time I looked it always went for an insanely big screen and crashed when trying to change that.09:48
tjaaltonI need to make some room on my ssd first to check the situation, but iirc I switched off from cirrus immediately after the install09:49
smbtjaalton, Yeah, which is a failure from my point of view ;)09:50
tjaaltoni'm using qxl it seems09:54
smbOne does not have that luxury with Xen. I mean we should be better with cirrus now as both KVM and Xen can use the kernel-mod driver09:57
smbAnd the boot issues should be solved too09:57
cristian_cHi11:07
cristian_cI've opened this bug report much time ago: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/97260411:07
ubot2Launchpad bug 972604 in linux (Ubuntu) "168c:001c [HP Compaq Presario C700 Notebook PC] Wireless led button doesn't switch colors" [Low,Triaged]11:07
cristian_cI've to open an upstream bug report. There is this wiki page: https://wiki.ubuntu.com/Bugs/Upstream/kernel11:08
cristian_cI've read it, but I've got some doubts yet. for example: [7.7.] Other information that might be relevant to the problem (please look in /proc and include all information that you think to be relevant):  While booted into the newest upstream mainline kernel only, execute the following via a terminal, and paste the results11:08
cristian_cwhat information from /proc can I add to the upstream bug report?11:08
cristian_cand then: [X.] Other notes, patches, fixes, workarounds:  Please provide a link to your Launchpad bug report11:08
cristian_cWhat exactly can I do about this specific point? Any ideas?11:09
ogra_apw, there are two (untested) patches for flo and mako on bug 1270248, could i get a PPA build with them to test ?13:00
ubot2Launchpad bug 1270248 in logrotate (Ubuntu) "/var/log fills up disk space on phone" [High,Confirmed] https://launchpad.net/bugs/127024813:01

apwogra_, ack14:08
ogra_apw, thx14:17
rsalvetiogra_: I still think we should fix this differently somehow14:47
rsalvetiogra_: otherwise we'd need to patch every kernel14:47
rsalvetifrom every vendor14:47
rsalvetiwe need a way for the log to have a limit in size, and drop the rest that overflows it14:47
rsalvetilike a ring-buffer but for whatever we store in syslog14:48
ogra_rsalveti, you still dont want a notice message every 20sec14:48
rsalvetiogra_: that's fine14:48
rsalvetias long it doesn't cost you anything14:48
ogra_it eats the log14:48
rsalvetiright, but we shouldn't care about that, as long we limit the log14:48
rsalvetithis is not a desktop, it's a phone14:48
rsalvetiandroid is ridiculously verbose, but it's not storing anything in the disk14:50
ogra_rsalveti, only the chargers are 14:50
ogra_the rest is normal14:50
rsalvetiright, but do we really want to keep those logs around?14:50
rsalvetiand still, it's specific to a device14:51
rsalvetiwhich annoys me as we need to start preparing a similar change for every build we have (and will have)14:51
ogra_can we discuss this at or after the meeting 14:51
* ogra_ tries to get something in his stomack atm ... had no chance to eat today yet14:52
rsalvetisure, I believe it'd be good to have some sort of uds session (but out of uds) :-)14:52
ogra_done14:58
ogra_rsalveti, so the issue is that the kernel logs to a ringbuffer ... dmesg will be completely spammed away with batteray messages after 2min14:58
rsalvetiogra_: but that is fine14:59
rsalvetiand expected14:59
ogra_i agree we need to limit logging more as well, but we also need to get rid of tehse spammers, 14:59
ogra_no14:59
rsalvetiwe don't need to care, really14:59
rsalvetiand we shouldn't care14:59
rsalvetias that's specific to the kernel we have14:59
ogra_thats not expected by me ... if i want to see kernel messages i dont want to see 2000 the same battery message 14:59
ogra_it is *only* one place in the klernel that spams 15:00
rsalvetiwell, then just run dmesg right after boot15:00
ogra_then iu can use /var/log/dmesg, that gets copied on boot 15:00
rsalvetiyou shouldn't be able to get a useful dmesg output (since boot) after you used the phone for a while anyway15:00
ogra_but i want to be able to read normal kernel messages too 15:00
rsalvetiright, but you're expecting too much15:00
ogra_and writing rubbish to all logs every 20sec is not acceptable15:00
rsalvetias I said, this is specific to vendor/device/kernel15:00
ogra_no15:00
rsalvetiand I want us to have a solution that is common for whatever kernel we use15:01
ogra_this is specific to only power mgmt drivers15:01
ogra_look at the patches15:01
rsalvetiright, a kernel tree15:01
rsalvetiwe don't even know if the vendor will be using the same drivers15:01
ogra_its as quiet as my desktop with these added15:01
ogra_i'm willing to maintain patches for this 15:01
ogra_i'm not willing to lose my logs to spam for that 15:01
ogra_esüpecially if we restrict them in size and you lose them way earlier15:02
apwogra_, i have kernels ready to upload, are we a go, or not go15:03
apwrsalveti, ^15:03
ogra_apw, please upload to the PPA, i want to test on the weekend15:03
ogra_(we can still wipe them, right ?)15:04
rsalvetiogra_: I got a pending flo kernel in there that I want to upload today still15:04
rsalvetibut I believe it's fine to upload this anyway15:04
ogra_apw, can you hold back until that landed ? 15:04
rsalvetiuntil we work on a better solution15:04
rsalvetiogra_: I'm fine to land this today15:04
ogra_good15:04
rsalvetiall I'm saying is that I want us to work on a more generic solution as well15:05
rsalvetiapw: so please, push them to the ppa :-)15:05
apwrsalveti, ack15:09
apwrsalveti, ok both are built and published in the ppa16:41
rsalvetiapw: great, thanks for the heads up16:41
=== hatch__ is now known as hatch
ogra_apw, oh, and since i had pinged you about that, i worked around the bootchart CPU issue i had by simply forcing all cores online during boot, but i could imagine the server team will want bootcharts for their arm devices too and will run into something similar, so the CPU logic in bootchart probably deserves some attention17:36
bladibladoes anyone have a hint how to get this one "Realtek Semiconductor Co., Ltd. Device 5249 " up and running?20:33

wmphello, i build my own kernel package, and i have problem with brx2 (broadcom ethernet NIC)23:19
