| LocutusOfBorg | hello apw sforshee which vbox driver are you using nowadays? 5.2.8 is out, should I ping you or you will take the one mainline? | 07:34 |
|---|---|---|
| * LocutusOfBorg hopes for the latter | 07:34 | |
| LocutusOfBorg | apw, ping :) | 12:01 |
| LocutusOfBorg | BTW virtualbox is "regressed" because some new tests see that the built kernel and the one in Ubuntu differ... obviously | 12:01 |
| apw | yep, dkms is a pile of crap, it has no idea how to compare versions if there is not a manual version | 12:08 |
| LocutusOfBorg | apw, second question, are you using vbox mainline kernel drivers? | 12:18 |
| apw | we are still at .26 i think, and i believe not using those, because the only one which existed at the time was blowin up | 12:20 |
| apw | but i would have to defer to sforshee for accurate memory on that | 12:20 |
| LocutusOfBorg | please delete it, and switch to the mainline version :) | 12:22 |
| apw | mainline only provides one of them at 4.15 level right ? | 12:25 |
| LocutusOfBorg | no, even 4.14 IIRC | 12:35 |
| ricotz | hi, is bionic getting 4.16 after all? | 12:58 |
| sforshee | LocutusOfBorg: bionic currently has version 5.2.6-dfsg-5, we are using the in-tree vboxvideo driver which I believe is the only one that exists in 4.15 | 13:04 |
| sforshee | once the 5.2.8 package promotes I can update to that | 13:06 |
| === Nafallo_ is now known as Nafallo | ||
| LocutusOfBorg | sforshee, sorry, I mean, don't use the vboxvideo from vbox, but use the one inside the kernel source tree | 13:50 |
| LocutusOfBorg | it is now fixed | 13:50 |
| LocutusOfBorg | git tag --contains ce10d7b4e8e3574b9616e54a09d64521b9aeb8b6 | 13:51 |
| LocutusOfBorg | v4.15 | 13:51 |
| LocutusOfBorg | since 4.15~rc1 | 13:51 |
| sforshee | LocutusOfBorg: yes, that's what I meant by "using the in-tree" driver. We've been using that in-kernel one rather than the one we import from vbox-guest-dkms for a while now | 13:51 |
| LocutusOfBorg | I don't get this: [14:06:00] <sforshee> once the 5.2.8 package promotes I can update to that | 13:52 |
| LocutusOfBorg | I mean: please continue to use the in-tree one then | 13:52 |
| sforshee | LocutusOfBorg: we still import the vbox-guest-dkms drivers but disable the vboxvideo one from there | 13:52 |
| LocutusOfBorg | oh... ok, I don't see the need, but fine | 13:53 |
| sforshee | it provides other functions than the video doesn't it? | 13:53 |
| sforshee | otherwise maybe we don't need to do that anymore | 13:53 |
| LocutusOfBorg | vboxsf and so on... | 13:54 |
| LocutusOfBorg | ok | 13:54 |
| LocutusOfBorg | just disable vboxvideo from there then | 13:54 |
| sforshee | yeah, our import script does that automatically now | 13:54 |
| LocutusOfBorg | ack | 13:54 |
| LocutusOfBorg | unfortunately such drivers might have a bug | 13:54 |
| LocutusOfBorg | KERNEL=="vboxguest", NAME="vboxguest", OWNER="root", MODE="0660" | 13:54 |
| LocutusOfBorg | KERNEL=="vboxuser", NAME="vboxuser", OWNER="root", MODE="0666" | 13:54 |
| apw | (see truth you need sforshee :) | 13:55 |
| LocutusOfBorg | this is the content of: debian/virtualbox-guest-dkms.udev | 13:55 |
| LocutusOfBorg | anyhow, it is fine to grab even 5.2.8 right now, but I don't think there are updates there | 13:57 |
| sforshee | LocutusOfBorg: hmm, so you're saying without those udev rules having those drivers in the kernel may not provide any benefit? | 13:59 |
| sforshee | I mean, if you think there's no benefit in having them shipped with the kernel now we should talk about removing them | 14:00 |
| sforshee | would save me some effort at minimum ;-) | 14:00 |
| sforshee | I'm unfamiliar with the history of why we started shipping them in the kernel packages anyhow | 14:00 |
| LocutusOfBorg | I didn't receive any complain about them, so maybe they are fixed now, and I should remove the udev rule too | 14:00 |
| LocutusOfBorg | unfortunately it has been added too many years ago | 14:01 |
| LocutusOfBorg | so, I prefer to "don't touch if it isn't broken" | 14:01 |
| LocutusOfBorg | BTW please grab 5.2.8, the difference with 5.2.6 is *only* kernel 4.15 fixes, so, before trying to fix, update the tarball :) | 14:01 |
| sforshee | ack, will update | 14:02 |
| LocutusOfBorg | (I'm about to send a diff) | 14:02 |
| LocutusOfBorg | https://paste.ubuntu.com/p/WnZgVw7h5C/ | 14:03 |
| LocutusOfBorg | there is a new timer function, probably some fixes in timer syncronization host/guest | 14:03 |
| LocutusOfBorg | and the most important thing is a new structure | 14:03 |
| LocutusOfBorg | + * Intel PCID invalidation types. | 14:03 |
| LocutusOfBorg | (I presume, because upstream refuses to release CVE patches), it has something to do with spectre/meltdown | 14:04 |
| LocutusOfBorg | + /* Clear bits which we don't pass through for security reasons. */ | 14:04 |
| LocutusOfBorg | + pDst->Attr.fMode &= ~(RTFS_UNIX_ISUID | RTFS_UNIX_ISGID | RTFS_UNIX_ISTXT); | 14:04 |
| LocutusOfBorg | apw, can you please update the vbox hint, I don't want to loose days to fix dkms, better have a vbox versionless hint for now | 14:05 |
| apw | not gong to make it versionless | 14:06 |
| LocutusOfBorg | it is clearly a bad test, and I don't need autopkgtests because in case of dkms failure I get reports from debian and Ubuntu *minutes* after dinstall, really | 14:06 |
| apw | i read the logs before updating the hints normally | 14:06 |
| amitk | apw: do you guys provide linux-tools-common for the mainline builds at http://kernel.ubuntu.com/~kernel-ppa/mainline/ ? | 14:39 |
| amitk | I'm looking for perf | 14:39 |
| apw | nope we don't make tools mostly, because they don't work in a cross environment | 14:39 |
| apw | likely we don't do them at all, when we could for x86 at least | 14:39 |
| * amitk nods | 14:39 | |
| Misha_R | Hello! A friend is looking for a HWE kernel DEB for Ubuntu LTS from December. He wants a version before the Meltdown/Spectre patches. | 15:15 |
| Misha_R | Where can he find such a DEB? | 15:15 |
| apw | Misha_R, in the launchpad librarian ... | 15:21 |
| apw | https://launchpad.net/ubuntu/+source/linux/+publishinghistory | 15:22 |
| apw | Misha_R, ^ that has the complete publishing history for the kernel; oh you wanted linux-hwe | 15:22 |
| apw | https://launchpad.net/ubuntu/+source/linux-hwe/+publishinghistory | 15:22 |
| apw | Misha_R, ^ so that one | 15:22 |
| apw | iirc -26 was the first one with those changes, but you should check | 15:23 |
| Misha_R | apw thanks | 15:27 |
| Misha_R | apw: we can't seem to find the way to download the actual debs. For example we try this one https://launchpad.net/ubuntu/+source/linux-hwe/4.10.0-41.45~16.04.1 . There is a list of binary files but there does ot seem to be a way to download them | 15:44 |
| Misha_R | Is rebuilding from source the only option? | 15:45 |
| TJ- | Misha_R: https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/ppa/+build/13771372 | 15:53 |
| TJ- | Misha_R: That's the link from the page you referenced, under "Builds > amd64" | 15:54 |
| Misha_R | Thanks! | 16:00 |
| Misha_R | TJ-: thanks! | 16:01 |
| raidghost | TJ had a question about modify dvb amount. Possible to turn the limit of 8 up to 16 ? | 17:21 |
| raidghost | TJ-: Did you get any answer for that dvb question? | 17:22 |
| TJ- | raidghost: no I didn't... create a bug report so we can log/follow it | 17:22 |
| raidghost | TJ-: Where to make that kind of report? not that into this things :p | 17:23 |
| TJ- | !bug ~ raidghost | 17:23 |
| TJ- | grrr | 17:23 |
| TJ- | !bug | raidghost | 17:23 |
| ubot5` | raidghost: If you find a bug in Ubuntu or any of its derivatives, please report it using the command « ubuntu-bug <package> » - See https://help.ubuntu.com/community/ReportingBugs for other ways to report bugs. | 17:23 |
| TJ- | raidghost: report it against the package "linux" | 17:23 |
| raidghost | Have to figure out how to explain the thingy. not good with words | 17:24 |
| raidghost | thought that it was the driver i had to rebuild. but if its the kernel. Its a bit more not easy. | 17:26 |
| TJ- | raidghost: "Increase DVB_MAX_ADAPTERS from 8 to 16 in kernel config" and then explain why (because there are 4 cards each with 4 devices on) | 17:28 |
| TJ- | raidghost: tell me the bug once you're created it and I'll add some commentary | 17:28 |
| raidghost | TJ-: okey ;) | 17:35 |
| raidghost | TJ-: Just a quick question. Since the host that i want to type the ubuntu-bug thingy on doesnt have graphical. is that needed to get that box that selects all the hardware information? | 18:49 |
| raidghost | TJ-: Just created it. link is in PM | 19:22 |
| Misha_R | Excuse me, another question again | 19:36 |
| Misha_R | With Xenial (LTS) and the HEW kernel, how should one decide whether to install linux-image or linux-image-extras ? | 19:37 |
| Misha_R | I could not find any explanations later than 14.04 | 19:37 |
| apw | you always need linux-image add linux-image-extra if you are on hardware | 21:12 |
| thresh | I always install -extra, because I've been burned too many times upgrading my OS and being unable to boot or no network card up. | 21:13 |
| mozmck | What is in the -extra package, and should a mainline build create one? | 21:34 |
| apw | -extra has modules you don't need on a virtual machine, mainline builds do not make one because they do no split at all, linux-image is "fat" | 21:47 |
| mozmck | apw: thanks. I'm running preempt-rt and no virtual machines. | 22:28 |
