apw | ogra_, this syslog vomit, which kernel is this | 11:45 |
---|---|---|
ogra_ | uh, ask jdstrand, i think it is mako | 11:46 |
ogra_ | root@ubuntu-phablet:/# tail -1 /var/log/syslog | 11:47 |
ogra_ | Feb 14 12:47:09 ubuntu-phablet kernel: [53723.068756] adjust_soc: ibat_ua = 0, vbat_uv = 4326558, soc = 100, batt_temp=290 | 11:47 |
ogra_ | yep, looks like mako | 11:47 |
apw | you 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 |
apw | oh heh | 11:48 |
ogra_ | it wrote this line 5 times since we speak (i have a tail -f running) | 11:49 |
* ogra_ takes a look at maguro | 11:50 | |
apw | ogra_, so that is device specific i suspect | 11:50 |
ogra_ | same thing on maguro | 11:50 |
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 = 0 | 11:50 |
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 = 0 | 11:50 |
apw | yeah but a totally different mesage | 11:50 |
ogra_ | even on a shorter cycle | 11:50 |
apw | sigh, these people are full of crap | 11:50 |
ogra_ | as i told you :) | 11:51 |
* apw does wonder why we have syslog running though on such small disks | 11:51 | |
ogra_ | android drivers ... | 11:51 |
ogra_ | apw, we plan to restrict it | 11:51 |
apw | i assume they don't which is why they get away with it | 11:51 |
ogra_ | currently we need it for debugging indeed | 11:51 |
ogra_ | enduser devices will have limits set for logging | 11:51 |
apw | ogra_, which is maguro, the galaxy nexus ? | 11:52 |
ogra_ | (and logrotate throw away logs instead of keeping them compressed) | 11:52 |
ogra_ | yeah | 11:52 |
apw | i thought that one was dead a buried | 11:53 |
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 others | 11:54 |
ogra_ | apw, maguro will be dead and buried soon (once we default to a 4.4 base) but isnt until then | 11:55 |
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_ | *flo | 11:57 |
apw | ogra_, could yu find out what the message is in that one, when it has charged :) | 12:06 |
apw | and i can get some bits uploaded to the ppa for these | 12:06 |
ogra_ | yep, just charging | 12:06 |
apw | ogra_, 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 still | 12:07 |
ogra_ | i'll add excerpts for all the devices we care about to the bug | 12:07 |
apw | ogra_, thanks | 12:11 |
rsalveti | ogra_: apw: they are really verbose, even more when you try to suspend it | 12:21 |
rsalveti | which 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 |
rsalveti | well, I think it's expected from the kernel perspective to have such logs | 12:22 |
rsalveti | as it's very useful for debug | 12:22 |
rsalveti | we just shouldn't store them | 12:22 |
rsalveti | or 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 syslog | 12:23 |
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 |
rsalveti | well, 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 |
rsalveti | logs are usually a good thing (that's why android is so verbose), we just shouldn't store them | 12:26 |
ogra_ | but that will then only have the battery/charger messages | 12:26 |
ogra_ | yes, but that means using the rigbuffer (dmesg) | 12:27 |
ogra_ | *ring | 12:27 |
rsalveti | that's fine, at least it's still useful if you're debugging | 12:27 |
rsalveti | if we remove the messages, it'll just be harder to debug issues | 12:27 |
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 |
apw | ogra_, http://people.canonical.com/~apw/mako-trusty/ is that message moved to debug, be interested if that makes it not end up in the logs | 12:44 |
apw | rsalveti, how goes testing those yama kernels | 12:45 |
ogra_ | apw, no mako for testing here | 12:45 |
rsalveti | apw: testing all the kernels as we speak | 12:46 |
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 stupid | 12:46 | |
apw | people who have kit need to have all of the supported kit or not bother | 12:46 |
apw | else we are just wasting peoples time | 12:46 |
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 now | 14:00 | |
rtg | apw, remember to upload to the c-k-t PPA per bjf request | 14:05 |
apw | rtg ack | 14:08 |
=== ara is now known as Guest55777 | ||
=== tyhicks` is now known as tyhicks | ||
apw | rtg, fire in the hole | 15:58 |
rsalveti | apw: rtg: missing a new kernel release for manta | 18:14 |
rsalveti | after you updated the tree with the yama changes | 18:15 |
rsalveti | that would still be ppa-only (as it's on top of 4.4.2), but just noticed it's not there yet | 18:15 |
rtg | rsalveti, k, lemme figure out what happened. I think apw was doing that at the time. | 18:17 |
rtg | rsalveti, looks like we (likely me) didn't finish packaging and uploading. I'll git 'er done here in a bit. | 18:25 |
rsalveti | rtg: great, thanks | 18:28 |
rtg | rsalveti, linux-manta_3.4.0-5.21 uploaded to the c-k-t PPA | 18:35 |
rsalveti | rtg: awesome, thanks | 18:40 |
hallyn | apw: hi, any comments on the overlayfs unprivileged whiteout patch? (stgraber will be poking me soon about it I'm sure :) | 19:39 |
chiluk | what kernel trace tool produces output like this ? | 22:32 |
