apwogra_, this syslog vomit, which kernel is this11:45
ogra_uh, ask jdstrand, i think it is mako11:46
ogra_root@ubuntu-phablet:/# tail -1 /var/log/syslog11:47
ogra_Feb 14 12:47:09 ubuntu-phablet kernel: [53723.068756] adjust_soc: ibat_ua = 0, vbat_uv = 4326558, soc = 100, batt_temp=29011:47
ogra_yep, looks like mako 11:47
apwyou can tell it is mako from that line ?11:47
ogra_seems to write that every 20sec here for me 11:47
ogra_no, i can tell by following the cable that goes from my laptop to the device ;) 11:48
ogra_thats actually my output above 11:48
apwoh heh11:48
ogra_it wrote this line 5 times since we speak (i have a tail -f running)11:49
* ogra_ takes a look at maguro11:50
apwogra_, so that is device specific i suspect11:50
ogra_same thing on maguro11:50
ogra_Feb 14 12:49:33 ubuntu-phablet kernel: [ 4449.108245] max17040 4-0036: online = 1 vcell = 3767500 soc = 29 status = 1 health = 1 temp = 250 charger status = 011:50
ogra_Feb 14 12:50:24 ubuntu-phablet kernel: [ 4499.191436] max17040 4-0036: online = 1 vcell = 3852500 soc = 29 status = 1 health = 1 temp = 260 charger status = 011:50
apwyeah but a totally different mesage11:50
ogra_even on a shorter cycle 11:50
apwsigh, these people are full of crap11:50
ogra_as i told you :) 11:51
* apw does wonder why we have syslog running though on such small disks11:51
ogra_android drivers ... 11:51
ogra_apw, we plan to restrict it 11:51
apwi assume they don't which is why they get away with it11:51
ogra_currently we need it for debugging indeed11:51
ogra_enduser devices will have limits set for logging 11:51
apwogra_, which is maguro, the galaxy nexus ?11:52
ogra_(and logrotate throw away logs instead of keeping them compressed)11:52
ogra_yeah11:52
apwi thought that one was dead a buried11:53
ogra_here is manta:11:54
ogra_Feb 14 12:53:42 ubuntu-phablet kernel: [  488.998610] battery: l=100 v=4275 c=-123 temp=29.7 h=1 st=1 11:54
ogra_same thing 11:54
ogra_(N10)11:54
ogra_manta does it once a minute ... less frequent than the others11:54
ogra_apw, maguro will be dead and buried soon (once we default to a 4.4 base) but isnt until then11:55
ogra_(not sure you need to care for it though) 11:56
ogra_(i wouldnt :P )11:56
ogra_my fo (N7 2013) is sadly out of battery ... but i bet it does the same too 11:57
ogra_*flo11:57
apwogra_, could yu find out what the message is in that one, when it has charged :)12:06
apwand i can get some bits uploaded to the ppa for these12:06
ogra_yep, just charging 12:06
apwogra_, though first i'll get you a test kernel with it moved to pr_debug and make sure they don't ned up in the logs still12:07
ogra_i'll add excerpts for all the devices we care about to the bug 12:07
apwogra_, thanks12:11
rsalvetiogra_: apw: they are really verbose, even more when you try to suspend it12:21
rsalvetiwhich happens like a lot when you use it as a phone :-)12:22
ogra_rsalveti, right, we need to get rid of that 12:22
rsalvetiwell, I think it's expected from the kernel perspective to have such logs12:22
rsalvetias it's very useful for debug12:22
rsalvetiwe just shouldn't store them12:22
rsalvetior at least put a small limit 12:23
ogra_rsalveti, well, if we out a small limit in you will only see these messages in your syslog12:23
ogra_i dont think we want charger status reported every 20sec 12:23
ogra_(no matter if the device is on or not)12:24
rsalvetiwell, then do you really want to patch every kernel we had to remove those messages?12:24
ogra_rsalveti, in the long term we will i fear 12:26
ogra_or skip kernel logging at all and rely on the ringbuffer 12:26
rsalvetilogs are usually a good thing (that's why android is so verbose), we just shouldn't store them12:26
ogra_but that will then only have the battery/charger messages12:26
ogra_yes, but that means using the rigbuffer (dmesg)12:27
ogra_*ring12:27
rsalvetithat's fine, at least it's still useful if you're debugging12:27
rsalvetiif we remove the messages, it'll just be harder to debug issues12:27
ogra_well, i still dont think every 20sec a battery ping is relevant to debugging 12:28
ogra_i agree that ril messages might be ... but for that we have the radio logcat log ... 12:29
apwogra_, http://people.canonical.com/~apw/mako-trusty/ is that message moved to debug, be interested if that makes it not end up in the logs12:44
apwrsalveti, how goes testing those yama kernels12:45
ogra_apw, no mako for testing here 12:45
rsalvetiapw: testing all the kernels as we speak12:46
ogra_(thats my main phone ... i dont do tests on it ... company needs to supply me one :P )12:46
* apw calls this whole thing stupid12:46
apwpeople who have kit need to have all of the supported kit or not bother12:46
apwelse we are just wasting peoples time12:46
ogra_rsalveti, thanks !12:46
ogra_apw, well, i have flo, maguro an manta ... the mako is my private one and i dont want to have to set up calendar and my accounts multiple times a week (or have to install the click packages i use on a daily basis)12:49
* smb wants a sushi now14:00
rtgapw, remember to upload to the c-k-t PPA per bjf request14:05
apwrtg ack14:08

apwrtg, fire in the hole15:58
rsalvetiapw: rtg: missing a new kernel release for manta18:14
rsalvetiafter you updated the tree with the yama changes18:15
rsalvetithat would still be ppa-only (as it's on top of 4.4.2), but just noticed it's not there yet18:15
rtgrsalveti, k, lemme figure out what happened. I think apw was doing that at the time.18:17
rtgrsalveti, looks like we (likely me) didn't finish packaging and uploading. I'll git 'er done here in a bit.18:25
rsalvetirtg: great, thanks18:28
rtgrsalveti, linux-manta_3.4.0-5.21 uploaded to the c-k-t PPA18:35
rsalvetirtg: awesome, thanks18:40
hallynapw: hi, any comments on the overlayfs unprivileged whiteout patch?  (stgraber will be poking me soon about it I'm sure :)19:39
chilukwhat kernel trace tool produces output like this ?22:32
