| xnox | apw: 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/15 | 11:18 |
|---|---|---|
| ubot5 | Launchpad bug 1297012 in partman-auto (Ubuntu) "hyper-v: Manual partitioning formats /boot with ext2 file-system" [High,Confirmed] | 11:18 |
| xnox | apw: ogasawara: otherwise hyperv (well azure) cannot freeze/migrate default installs off ubuntu (as it uses ext2 for /boot =( ) | 11:19 |
| xnox | apw: 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 |
| apw | xnox, 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 context | 11:32 |
| apw | xnox, oh these are very new bits, so no they won't be currently | 11:33 |
| xnox | apw: 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 |
| apw | xnox, right, but as you point out they could select something else, rather than a lot of backporting | 11:35 |
| xnox | apw: 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 |
| apw | as they know it does not work | 11:35 |
| apw | xnox, it is not clear why they can't preseed it | 11:35 |
| xnox | apw: it's not up to them to select. but for the guest-os / any client workload on azure. | 11:36 |
| xnox | apw: it seems that telling all users to do something else doesn't work. | 11:36 |
| xnox | (well ubuntu based client custom images) | 11:36 |
| apw | xnox, 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 thinking | 11:36 |
| apw | xnox, the images most people use on azure are supplied by us, this would be hyper-v on a local install only prety much | 11:37 |
| xnox | apw: 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 |
| xnox | apw: right, ENOCLUE. | 11:37 |
| xnox | apw: 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 |
| xnox | such that it becomes freezable, but we don't need to increase it's disk space. | 11:38 |
| apw | the unfreezability looks to be related to not having a journal | 11:38 |
| xnox | also we should finally make grub2 not require /boot for just lvm2 based installs, as it can parse things off it. | 11:38 |
| xnox | =( | 11:38 |
| * xnox does not want /boot with a journal..... | 11:38 | |
| apw | xnox, on my boxes i have no /boot on my lvm installs, no idea why we need it | 11:41 |
| apw | xnox, it is not clear whether this second fix would stand alone, it might well do | 11:42 |
| xnox | apw: hm, maybe cjwatson fixed that already.... | 11:45 |
| xnox | apw: i'll make a note to self to retest that. | 11:45 |
| apw | cirtainly 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 grub | 11:45 |
| apw | xnox, so this is for .2 right? so will be with an lts-u kernel ? | 11:48 |
| apw | we'd not care for anything older i presume | 11:49 |
| xnox | apw: well if those ext2 patches are in u's kernel, then yeah lts-u-hwe / .2 target is good. | 11:49 |
| xnox | apw: if those patches are only in v's kernel, then we are looking at .3 target. | 11:49 |
| xnox | apw: 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 |
| apw | they are 3.18-rc3 so very new, not in anything at all right now | 11:51 |
| xnox | apw: cherrypick!!!! what could possibly go wrong?! =) | 12:09 |
| apw | xnox, heh, we shall see if they even build, let alone work | 12:10 |
| xnox | apw: cause 3.17/3.18 are so wonderful with all the regressions since 3.16..... =)))) | 12:10 |
| apw | xnox, 3.18 isn't feeling toooo bad to me | 12:19 |
| xnox | apw: i'm on 3.17.4 on my dev hardware and "i don't like it" (big brother quote) | 12:19 |
| xnox | apw: 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 | |
| cking | amitk, i just tried to send some idlestat patches to sched-tools@linaro.org and my mailer complained it did not exist | 13:43 |
| === vmesons is now known as vmeson | ||
| amitk | cking: I see the patches.... | 14:01 |
| cking | amitk, yep, I cc'd you on them ;-) | 14:01 |
| cking | amitk, 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 them | 14:02 |
| amitk | cking: I think you subscribed me to the report, I saw it today | 14:03 |
| amitk | cking: I'll look at the sched-tools alias later today, thanks for reporting. And thanks for the patches. | 14:04 |
| cking | ok, cool, just wanted to keep you in the loop about the outstanding issues ;-) | 14:04 |
| amitk | cking: much appreciated | 14:04 |
| cking | amitk, BTW, idlestat still could do with a man page ;-) | 14:05 |
| amitk | cking: 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 guess | 14:16 |
| amitk | cking: but if you file a bug on bugs.linaro.org, atleast it'll stay on the radar | 14:16 |
| cking | okay will do | 14:17 |

If the question is should I file a bug for something, likely you can assume yes. | ||
| kgunn | ogasawara: hey curious, we've recently been discussing how to automate some testing for rotation | 19:51 |
| kgunn | curious if there is some known kernel tool/trick that could be used to | 19:52 |
| kgunn | inject sensor events, e.g. mock rotation/orientation sensor firing | 19:52 |
| ogasawara | kgunn: I don't know anything off the top of my head, but let me sync with my guys and get back to you | 19:53 |
