xnoxapw: ogasawara: yo, ms wants some kernel patches for trusty ideally to enable ext2 freezing https://bugs.launchpad.net/ubuntu/+source/partman-auto/+bug/1297012/comments/1511:18
ubot5Launchpad bug 1297012 in partman-auto (Ubuntu) "hyper-v: Manual partitioning formats /boot with ext2 file-system" [High,Confirmed]11:18
xnoxapw: ogasawara: otherwise hyperv (well azure) cannot freeze/migrate default installs off ubuntu (as it uses ext2 for /boot =( )11:19
xnoxapw: ogasawara: are those ext2 patches in 14.10 or 15.04 kernel yet, or will be? and will they make it into hwe kernel?11:19
apwxnox, i know they have asked before, so we may well have done so.  though it also depends if we are using ext2 or ext4 to mount ext2 in that context11:32
apwxnox, oh these are very new bits, so no they won't be currently11:33
xnoxapw: we are using ext2 file format for /boot & we do have CONFIG_EXT4_USE_FOR_EXT23=y, however i don't think that makes ext2 freezable without those patches.11:34
apwxnox, right, but as you point out they could select something else, rather than a lot of backporting11:35
xnoxapw: i'd rather have kernel changed with those patches, than changing installer default partitioning filesystems in the default configuration in a trusty point release.11:35
apwas they know it does not work11:35
apwxnox, it is not clear why they can't preseed it11:35
xnoxapw: it's not up to them to select. but for the guest-os / any client workload on azure.11:36
xnoxapw: it seems that telling all users to do something else doesn't work.11:36
xnox(well ubuntu based client custom images)11:36
apwxnox, right but the only reason this is a problem is because they believe they can make a consistant snapshot of the machine if they freeze it, which btw, i think is flawed thinking11:36
apwxnox, the images most people use on azure are supplied by us, this would be hyper-v on a local install only prety much11:37
xnoxapw: i do hope they are not exposing that to people, when they clearly see a given VM is not freezable.... i hope they only do so when they think they actually can do it.11:37
xnoxapw: right, ENOCLUE.11:37
xnoxapw: i haven't looked into partman-auto enough, hopefully we can make /boot ext4 without journaling / extents / etc. (e.g. more like an ext2 thing)11:38
xnoxsuch that it becomes freezable, but we don't need to increase it's disk space.11:38
apwthe unfreezability looks to be related to not having a journal11:38
xnoxalso we should finally make grub2 not require /boot for just lvm2 based installs, as it can parse things off it.11:38
* xnox does not want /boot with a journal.....11:38
apwxnox, on my boxes i have no /boot on my lvm installs, no idea why we need it11:41
apwxnox, it is not clear whether this second fix would stand alone, it might well do11:42
xnoxapw: hm, maybe cjwatson fixed that already....11:45
xnoxapw: i'll make a note to self to retest that.11:45
apwcirtainly i have what i think is a P install using it, you need a 2048 block aligned first cylinder sort of thing else there isn't room in the gap for grub11:45
apwxnox, so this is for .2 right?  so will be with an lts-u kernel ?11:48
apwwe'd not care for anything older i presume11:49
xnoxapw: well if those ext2 patches are in u's kernel, then yeah lts-u-hwe / .2 target is good.11:49
xnoxapw: if those patches are only in v's kernel, then we are looking at .3 target.11:49
xnoxapw: and i don't have ubuntu kernels cloned here to confirm which kernel those patches are in, if at all, and/or need cherry-picking.11:50
apwthey are 3.18-rc3 so very new, not in anything at all right now11:51
xnoxapw: cherrypick!!!! what could possibly go wrong?! =)12:09
apwxnox, heh, we shall see if they even build, let alone work12:10
xnoxapw: cause 3.17/3.18 are so wonderful with all the regressions since 3.16..... =))))12:10
apwxnox, 3.18 isn't feeling toooo bad to me12:19
xnoxapw: i'm on 3.17.4 on my dev hardware and "i don't like it" (big brother quote)12:19
xnoxapw: using stock 14.04 LTS otherwise everywhere as it's the release i can trust =) after all the things i broke for 14.10 ;-)12:20
* xnox wishes for my SRUs to be accepted.....12:20
ckingamitk, i just tried to send some idlestat patches to sched-tools@linaro.org and my mailer complained it did not exist13:43
=== vmesons is now known as vmeson
amitkcking: I see the patches....14:01
ckingamitk, yep, I cc'd you on them ;-)14:01
ckingamitk, do you have access to the coverity scan for idlestat? there are a bunch more issues that need fixing that I wasn't so sure about the best way to fix them14:02
amitkcking: I think you subscribed me to the report, I saw it today14:03
amitkcking: I'll look at the sched-tools alias later today, thanks for reporting. And thanks for the patches.14:04
ckingok, cool, just wanted to keep you in the loop about the outstanding issues ;-)14:04
amitkcking: much appreciated14:04
ckingamitk, BTW, idlestat still could do with a man page ;-)14:05
amitkcking: honestly speaking it will probably happen only when we stop changing the options so much. Every few patches we change the behaviour a little. Lack of a spec, I guess14:16
amitkcking: but if you file a bug on bugs.linaro.org, atleast it'll stay on the radar14:16
ckingokay will do14:17

=== jsalisbury changed the topic of #ubuntu-kernel to: Home: https://wiki.ubuntu.com/Kernel/ || Ubuntu Kernel Team Meeting - Tues December 9th, 2014 - 17:00 UTC || If you have a question just ask, and do wait around for an answer! If the question is should I file a bug for something, likely you can assume yes.
kgunnogasawara: hey curious, we've recently been discussing how to automate some testing for rotation19:51
kgunncurious if there is some known kernel tool/trick that could be used to 19:52
kgunninject sensor events, e.g. mock rotation/orientation sensor firing19:52
ogasawarakgunn: I don't know anything off the top of my head, but let me sync with my guys and get back to you19:53
