arighiricotz, I think it's a mistake, I don't even see nvidia-530 in lunar10:52
arighiI'll double check11:10

ricotzI commented on https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-525/+bug/201549111:12
arighiricotz, yep, I see it in proposed for all the releases, but not in lunar (not yet at least)11:12

arighioh ok sorry, you meant in general, I was only checking in lunar11:12
ricotzyeah, those packages are broken11:13
arighiricotz, let me ask around :)11:13
ricotzarighi, thank you11:13
tseliotricotz, hey, what's up with the driver?13:32
ricotztseliot, hi, see https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-525/+bug/201549113:33

ricotztseliot, it seems bad to copy packages which ftbfs already in a PPA to the archive13:34
tseliotYes, I must've missed that. Only Lunar and bionic, apparently13:36
ricotztseliot, all of them, since i386 isn't picked up on the other series yet13:37
tseliotOh, I see. I thought you already had it in the PPA, and that 530 would be already whitelisted13:38
ricotzI have, but it seems it only enabled lunar :\13:38
tseliotWell, let me fix that build dep here13:40
ricotztseliot, there is another change for the PPA build, which seems to got fixed in debhelper13:41
ricotztseliot, https://paste.debian.net/plainh/b8c2b72c13:41
tseliotSo that it doesn't try it on all the packages?13:43
ricotzyes, it failed a couple of days ago, apparently not on your side, so seems to got fixed13:44
ahasenackrbasak: hi, is there a way to somehow highlight the "main" branch of development in a package? This list is very confusing to newcomers: https://code.launchpad.net/ubuntu/+source/nss14:05
ahasenack320 results!14:05
ahasenackI suppose this needs some new launchpad feature?14:06
ahasenackideally we would have "main" (or "devel"), then one branch per release, and the rest is just details (foo-security, foo-proposed, applied and not applied, etc)14:07
ahasenackrbasak: do you think we can let thunderbird be imported again? It's currently in the denylist, under "# uses up too much disk"14:23
ahasenackand, hm, openssh is in the denylist too? Just saw it, a few lines below. But we are importing it. Are these lists still being used?14:24
ahasenackbut thunderbird is indeed not imported (or the default branch wasn't flipped): https://code.launchpad.net/ubuntu/+source/thunderbird14:24
tseliotricotz, err... zstd is not in main, at least in bionic and focal. xnox , is there anything we can do about this?14:25
ricotztseliot, it is a build-dep which fine14:25
tseliotYes, I know it's the actual dependencies that are not allowed, but still14:26
rbasakahasenack: interesting choice of channel?14:48
ahasenackrbasak: bah14:48
ahasenackoff-by-one error14:48
ahasenackubuntu-devel is just above14:48
ghavilHowdy, I opened https://bugs.launchpad.net/ubuntu/+source/linux-aws/+bug/2016186 yesterday and was wondering if anyone here had advice as to how I could debug further. I'm not sure how actual disk I/O would translate into these cgroup files, maybe I just need to go understand that side in more depth first. Curious if folks have ideas 14:53
-ubottu:#ubuntu-kernel- Launchpad bug 2016186 in linux-aws (Ubuntu) "5.19 not reporting cgroups v1 blkio.throttle.io_serviced" [Undecided, New]14:53
arighighavil, hi, it really seems to be a cgroupv1 vs cgroupv2 issue, I think in kinetic with 5.19 we completely moved to cgroupv2, so you are not supposed to be able to use cgroupv1 anymore unless you tweak the kernel boot options/systems to enable the hybrid cgroupv1+cgroupv2 way15:23
ghavilHmmm oh boy that's what I'm worried about15:24
arighiyou can `grep cgroup /proc/mounts` to see the version of cgroup that is mounted15:24
arighiif it says cgroup2, well, you're using version 215:24
ghavilThese are for sure cgroups v1 configured, I was trying to get us to v2 but it's breaking a lot of stuff along the way 15:25
arighihave you seen this? https://docs.kernel.org/admin-guide/cgroup-v2.html#io-interface-files 15:25
arighiv2 has a slightly different ABI for blkio, but you should be able to enforce the same IO limitations and get the same stats using cgroupv215:26
ghavilYep, our issue w/ cgroups v2 is much more nuanced at the moment. Moving to it isn't an option for now 15:26
ghavilOur kernels are configured with 'systemd.unified_cgroup_hierarchy=0 systemd.legacy_systemd_cgroup_controller=true' for reference 15:27
ghavilIf 5.19 removes cgroups v1 support, I can work on pinning all of our stuff to 5.15 for now. Bummer though as this upgrade seems to be automatically happening for linux-aws packages (I don't think we opted into anything) and this is a Jammy node not Kinetic 15:28
ghavili.e. https://packages.ubuntu.com/jammy-updates/linux-aws is showing the bump to and my expectation was that cgroups v1 would continue to work for 22.04 at least 15:28
arighighavil, if you boot with unified_cgroup_hierarchy you should still be able to use cgroupv1, the kernel still supports it15:33
arighiI'm not sure if systemd is handling it properly.. I haven't done any test recently with cgroup115:33
arighilet me do a quick test...15:35
ghavilOkay sounds good, I'm been testing as well, I cannot get anything but '0's to appear in the /sys/fs/cgroup/blkio/blkio.throttle.io_serviced files on nodes w/ the cgroups v1 configuration & the kernel running. Downgrading to the 5.15 works and I unfortunately cannot change to cgroups v2 at this time. 15:36
arighighavil, which IO scheduler are you using? (grep . /sys/block/*/queue/scheduler)16:04
ghavil'[none] mq-deadline' it looks like16:05
ghavilSame for both of my testing 5.15 and 5.19 instances too 16:06
arighighavil, it looks like 'none' in 5.19 doesn't support cgroup blkio anymore (I'm trying to find the commit that changed this behavior)16:07
arighighavil, if you switch to bfq for example (apt install linux-modules-extra and modprobe bfq) then you can see IO stats in the blkio.* in cgroupfs16:07
ghavilOh interesting16:08
ghavilLemme give that a whirl 16:08
arighighavil, BTW you also need to enable the bfq scheduler for your block devices, like `echo bfq > /sys/block/<dev>/queue/scheduler`16:10
ghavilarighi: Dumb question, should I be installing 'linux-modules-extra-aws' or is 'linux-modules-extra' good enough? 16:26
ghavilAH HA that does work!16:29
ghavilI installed linux-modules-extra-aws for the record 16:29
arighighavil, yep modules-extra-aws is fine16:32
xnoxtseliot: i'm not sure what you are askinga bout zstd. what needs it in main? and if the request is legit we can promote it.16:33
tseliotxnox, apparently, nvidia-530 needs it as a build-dep, only on i386. I suppose it should be fine for now.16:34
arighighavil, however... I see the IO stats only in the blkio.bfq.* files, not in blkio.throttle.*, that means we are likely hitting a behavior change upstream (probably not many people noticed that, because it's cgroup1)16:34
ghavilarighi: Ah good catch, yeah I see that too, bummer but this is better than nothing 16:40
xnoxtseliot83:  packages in main and restricted, can build-depend on packages in universe/multiverse, if they don't produce runtime Depends on them.17:04
xnoxtseliot83:  i believe this has been true for long enough for you to use this fact everywhere.17:04
xnoxtseliot83:  https://lists.ubuntu.com/archives/ubuntu-devel/2016-March/039274.html17:04
xnoxi love the title of this email, as it is so easy to find17:04
tseliot83xnox, right, it's good enough for me. Thanks!17:05
xnoxi think we did it 2016, so all releases you can add Build-Depends: zstd and it will work17:05
jchittumghavil: for pinning to the 5.15 kernel, you can use `linux-aws-lts-22.04` package: https://packages.ubuntu.com/jammy/linux-aws-lts-22.0419:42
ghavilAh thanks for the tip! 19:45
ghaviljchittum: Is there a linux-gcp equivalent? I found https://packages.ubuntu.com/jammy/linux-azure-lts-22.04 for Azure 19:46
jchittumghavil: based on history there will be. it looks like the gcp kernel hasn't rolled to 5.19 yet. I believe that the Kernel team makes the -lts-$VERSION around rolls. I see linux-gcp-lts-20.04 and linux-gcp-lts-18.0421:35
