| AndreeeCZ | hi! Im trying to test the 4.4.0 kernel on rpi. I have downloaded and flashed ubuntu-embedded-16.04-raspi2.img and now would like to install this: | 10:57 |
|---|---|---|
| AndreeeCZ | https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/unstable/+sourcepub/5955607/+listing-archive-extra | 10:57 |
| AndreeeCZ | however, im not exactly sure of the procedure. Do i just download and install the .debs ?/ | 10:57 |
| AndreeeCZ | or is it better to add some repository and upgrade from there? | 10:58 |

| ppisati | AndreeeCZ: yep | 11:20 |
| apw | s/b 4 | 11:21 |
| ppisati | AndreeeCZ: or you can add the unstable ppa | 11:21 |
| AndreeeCZ | ppisati, thank you | 12:07 |
| AndreeeCZ | ppisati, whats the alternative to the usual /boot/config.txt ? | 12:07 |
| ppisati | AndreeeCZ: we don't mount the boot partition in /boot | 12:07 |
| AndreeeCZ | oh | 12:07 |
| ppisati | AndreeeCZ: we mount it in /boot/firmware | 12:07 |
| ppisati | AndreeeCZ: but the rest should be the same | 12:07 |
| AndreeeCZ | ok i see | 12:07 |
| AndreeeCZ | thank you | 12:09 |
| AndreeeCZ | ppisati, do you know which xserver-xorg-video- driver do i install for the VC4 driver? | 12:12 |
| ppisati | AndreeeCZ: no idea, sorry | 12:12 |
| ppisati | AndreeeCZ: i've never used xorg on that board | 12:12 |
| ppisati | AndreeeCZ: always headless | 12:12 |
| AndreeeCZ | ok thanks | 12:26 |
| rtg | AndreeeCZ, is that raspi2 kernel working for you ? I still haven't gotten around to testing it. | 12:27 |
| AndreeeCZ | rtg, it boots | 13:54 |
| AndreeeCZ | rtg, ssh works, apt too | 13:55 |
| rtg | AndreeeCZ, cool. | 13:55 |
| AndreeeCZ | the raspberry pi touchscreen works also | 13:55 |
| AndreeeCZ | i mean the screen part of it, dont know about touch yet | 13:55 |
| AndreeeCZ | i'm now struggling with how to get the VC4 driver | 13:55 |
| rtg | AndreeeCZ, I'm just happy that it boots :) | 13:55 |
| AndreeeCZ | ah okay :) | 13:55 |
| menace | Hi, i already asked in #ubuntu-devel, but i found with your newsletter this channel, so i wanted to ask... how big is the chance that kernel 4.5 ist ending up in 16.04? are there any advantages for doing that, or anything i can look for, if the possibility rises? personally i would prefer kernel 4.4 for 16.04, since we want to deploy several thousand desktop machines with the 16.04 stack, but one never knows... | 16:12 |
| menace | the timeframe seems to be quite narrow. kernel 4.5 can be speculated for the mid of march, you need (from your timetable extrapolated) ~ 2 weeks for testing and 7.4 is the kernel freeze. | 16:13 |
| menace | there are some news, that 4.4 is *decided*, but i cannot find any substantiation for that claim on your release schedules. | 16:45 |
| menace | or release notes. | 16:45 |

| cking | menace, 4.4 it will be | 17:00 |
| smb | menace, as cking said. 4.5 could never get enough testing until release | 17:00 |
| menace | ah, thanks for the information. | 17:06 |
| menace | just to satisfy my personal curiosity: what's the timeframe, complexity and tasks for testing a new kernel before an ubuntu release (besides running performance tests on several chipset architectures)? i could not find very much documentation about that in the wiki | 17:08 |
| cking | menace, it depends on the many factors, it changes every release depending on the kernel chosen, when it lands, the new features we enable and/or stuff we need to get stable and working well | 17:14 |
| cking | so, it's hard to say exactly | 17:14 |
| menace | okay, i can understand that. i just found https://wiki.ubuntu.com/Kernel/Debugging so at least i have some idea what things you have to test, though i'm sure, there are much more things, than on that site :D. thanks! :) | 17:19 |
| apw | menace, there is also a host of dependant packages which have to pass against the kernel before we can ship it | 17:34 |
| menace | ah, like special 3rd kernel modules or systemtap? | 17:35 |
| apw | right dkms packages and the like, plus we test glibc against the new headers we produce, that kind of thing | 17:58 |
| jdstrand | ogasawara: hi! I feel like in a recent xenial update, I started seeing this in my logs every 5 seconds: powercap intel-rapl:0: package locked by BIOS, monitoring only | 20:58 |
| jdstrand | ogasawara: have you heard of this? | 20:59 |
| * jdstrand wonders if it is a thermald change that was made on upgrade | 20:59 | |
| ogasawara | jdstrand: well that has to be annoying if it's every 5 secs. I've not personally heard, but let me send a note to cking and inquire. | 20:59 |
| jdstrand | thanks | 21:00 |
| jdstrand | I can say that stopping thermald makes the messages stop | 21:01 |
| jdstrand | but changing from QUIET to PERFORMANCE does not | 21:01 |
| jdstrand | ogasawara: oh, I was wrong. it is every 4 seconds :) | 21:01 |
| jdstrand | details... | 21:02 |
| rtg | jdstrand, thermald _was_ just updated, but I think there was also something related to intel-microcode | 21:17 |
| jdstrand | intel-microcode is still from november it seems | 21:19 |
| ogasawara | jdstrand: cking notes he's just recently seen the same issue and will be digging into it first thing on Mon | 22:42 |
