| xnox | apw: cking: do you by any chance know how to setup Qemu + NVMe + OVMF vm for testing? | 09:31 |
|---|---|---|
| cking | xnox, no idea about emulating NVMe in Qemu | 09:32 |
| xnox | somebody in 2013-02-25 was installing testing it like that. | 09:32 |
| xnox | https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1132681 | 09:32 |
| ubot2 | Launchpad bug 1132681 in ubiquity (Ubuntu) "U 12.10 LiveCD installer crashing during boot loader configuration on NVMe storage( QEMU + NVMe +OVMF )" [Undecided,New] | 09:32 |
| xnox | cking: otherwise i can propose some patches for you to try. | 09:33 |
| cking | xnox, that's a better plan, I can give them a spin on the H/W I have | 09:33 |
| xnox | cking: cool. | 09:34 |
| apw | xnox, not ever done that here eitehr | 09:45 |
| xnox | rbasak: what do you say on upgrading libvirt to 1.2 release? | 09:46 |
| cking | last time I tried QEMU was with OVMF I built from scratch from the tianocore sources | 09:51 |
| apw | if you read the description of this Qemu bug, it blows chunks in grub. didn't you have a similar issue cking? | 09:52 |
| cking | apw, yup, bug 1265483 | 09:53 |
| ubot2 | Launchpad bug 1265483 in grub-installer (Ubuntu Trusty) "Installer crashed when installing to an Intel NVMe SSD" [High,New] https://launchpad.net/bugs/1265483 | 09:53 |
| cking | apw, also my firmware can't boot off this device either, so that's another issue I face | 09:54 |
| apw | cking, i am somewhat expecting the next bug from this person to be that | 09:54 |
| apw | given they are using ovmf, it may only just have support for them much as your box does | 09:55 |
| cking | xnox, http://smackerelofopinion.blogspot.co.uk/2011/10/uefi-edk-ii-revised.html, although I guess the notes may be old now | 09:55 |
| cking | bah, the links are stake | 09:56 |
| cking | *stale | 09:56 |
| apw | 'stale' i thought those were 'pementant' links | 09:56 |
| cking | https://wiki.ubuntu.com/UEFI/EDK2 | 09:56 |
| cking | apw, somebody kindly redirected them | 09:57 |
| apw | xnox, ckings bug above also talks about grub failing during grub-install onto this type of device died | 09:57 |
| apw | (as does this new bug) | 09:57 |
| xnox | cking: well OVMF is packaged and it's simply -bios /usr/share/ovmf/OVMF.fd. | 09:57 |
| cking | xnox, that's way too easy ;-) | 09:57 |
| xnox | apw: sure. quite similar to the most recent patch to enable FusioIO devices. | 09:58 |
| xnox | cking: so you could try http://paste.ubuntu.com/6683593/ but that one assumes that /dev/nmve0n1 is device name and /dev/nmve0n1pX are partitions of thereof. But that's me guessing =/ ideally there would be some more precise way to know how nmve devices and partitions are numbered. | 10:00 |
| xnox | cking: in the mean time, i'll try to make this qemu-system to give me a nmve device. | 10:00 |
| cking | xnox, if you can figure out how to do that, then please let me know | 10:01 |
| xnox | cking: of course =) | 10:01 |
| xnox | cking: well, i booted something which does have nvme devices, they are numbered differently from what your device was however. | 10:13 |
| xnox | cking: qemu-system-x86_64 -bios /usr/share/ovmf/OVMF.fd -m 1024 -cdrom /var/cache/utah/iso/ubuntu/trusty-desktop-amd64.iso -drive file=nvme.img,if=none,id=D22 -device nvme,drive=D22,serial=1234 --enable-kvm | 10:13 |
| xnox | adjust memory, path to .iso, path to a device-drive image "nvme.img", no clue about the nvme parameters i copied them from blogger. | 10:14 |
| cking | xnox, that patch make grub install correctly | 10:14 |
| xnox | that does boot in EFI mode. | 10:14 |
| xnox | cking: \o/ excellent. Does it boot? | 10:14 |
| xnox | cking: cause grub2 might need patches to actually recognise the device =/ if that is the case it would be passing the ping-pong to cjwatson. | 10:14 |
| cking | xnox, I can't boot it 'cos the firmware does not support that device | 10:15 |
| cking | i.e. it can't find it, I need newer firmware I believe | 10:15 |
| xnox | cking: people on the forums patch stock motherboard firmwares with updated drivers all the time. E.g. i got "unofficial" firmware for my motherboard with updated intel drivers et.al. =) granted it may have come with extra NSA modules =) i got it off the forum post attachment over http ;-) | 10:17 |
| xnox | cking: so what do you want me to do? upload that patch into archive & respin ubiquity such that at least you will have daily desktop/server images tomorrow with it? | 10:18 |
| xnox | cking: and do we need this for 12.04.4? | 10:19 |
| cking | xnox, gimme a sec, I will just boot the box up from another image and see if the nvme grub looks sane | 10:19 |
| cking | xnox, it looks sane to me, so lets update it for the daily images | 10:21 |
| apw | xnox, have we asked the OR for their qemu command line etc, ask them when you ask them to test tommorows images | 10:21 |
| xnox | apw: >~cking ? | 10:21 |
| cking | apw, that makes sense | 10:22 |
| xnox | apw: i don't think i get to them at all. slangasek simply asked me to look into cking's bug report. | 10:22 |
| xnox | to talk that is. | 10:22 |
| xnox | cking: apw: https://bugs.launchpad.net/bugs/+bugs?field.searchtext=NVMe&search=Search+Bug+Reports&field.scope=all&field.scope.target= gives nice output, at least to me =) | 10:24 |
| cking | xnox, well, I'm OK with the fix, it installs grub correctly, I just need to talk to intel to get my firmware sorted to try a boot test | 10:25 |
| cking | so pop it in to the archive and respin is good for me. any objections apw? | 10:26 |

| cking | yep | 10:28 |
| cking | it may be a while before I can properly test this, I need to chat to various bods in intel | 10:29 |

| rbasak | xnox: zul and hallyn look after libvirt usually. zul uploaded 1.2.0-0ubuntu1 yesterday. | 10:58 |
| xnox | rbasak: excellent. didn't notice. | 10:59 |
| cking | thanks xnox | 11:01 |
| rtg | cking, just going back through my pre-holiday emails. For Trusty unstable (v3.13) I have set CONFIG_X86_INTEL_PSTATE=y. Is that OK without the thermal daemon ? | 13:18 |
| cking | rtg, well, yes and no | 13:20 |
| infinity | Is INTEL_PSTATE still a laughing stock of fan-spinning hilarity? | 13:33 |
| infinity | It's been shit for so many releases, I'll be amazed if it's finally fixed. | 13:33 |

| Kano | hi, has somebody a patch for nvidia + 3.13? | 14:41 |
| tseliot | Kano: it's in 14.04 | 14:49 |
| Kano | tseliot: i dont see it in the changelog | 14:49 |
| tseliot | let me check | 14:49 |
| tseliot | Kano: ok, maybe I confused it with 3.11 and 3.12. Do you have a dkms log for nvidia showing the failure? | 14:52 |
| Kano | tseliot: it builds,but i get: nvidia: Unknown symbol acpi_os_wait_events_complete (err 0) | 14:53 |
| tseliot | Kano: apparently they removed a symbol. I'll work around that next week | 14:56 |
| Kano | tseliot: well the patch in the nv forum seems to use >= instead of < | 14:58 |
| apw | tseliot, does that imply that the nvidia dkms is not working with 3.13 ? | 15:11 |
| tseliot | apw: I guess so, I haven't checked | 15:12 |
| tseliot | https://devtalk.nvidia.com/default/topic/644906/331-20-on-3-13-rc1-kernel/ | 15:12 |
| apw | tseliot, ok sounds like there are a couple of issues, but sounds like you are on the case | 15:14 |
| tseliot | apw: yes, whatever that is, I'll fix it. BTW where are we going to get 3.13 in 14.04? | 15:16 |
| apw | well ... "now" if the dkms packages we care about arn't borked | 15:16 |
| apw | i suspect "early next week" is most likely now | 15:17 |
| rtg | I'm thinking Monday | 15:18 |
| tseliot | I'll probably fix my packages next week | 15:19 |
| rtg | apw, did a practice rebase on unstable against current Linus tip and had aufs3 conflict. I resolved by dropping the conflicting chunk (i.e. the code the patch wanted to add), but could use a second set of eyeballs. perhaps you could take a quick pass at rebasing as well? | 16:12 |
| rtg | tseliot, fglrx isn't installing. you should get that on your todo list as well. | 16:16 |
| rtg | Setting up fglrx (2:13.101-0ubuntu5) ... | 16:16 |
| rtg | update-alternatives: using /usr/lib/fglrx/ld.so.conf to provide /etc/ld.so.conf.d/x86_64-linux-gnu_GL.conf (x86_64-linux-gnu_gl_conf) in auto mode | 16:16 |
| rtg | update-alternatives: error: error creating symbolic link `/usr/lib/x86_64-linux-gnu/xorg/extra-modules.dpkg-tmp': No such file or directory | 16:16 |
| rtg | dpkg: error processing fglrx (--configure): | 16:16 |
| tseliot | rtg: that's what I meant when I said that I would fix my packages ;) | 16:17 |
| apw | rtg, will do | 16:18 |
| apw | rtg, so its not a "just drop that hunk job" | 16:30 |
| rtg | apw, ok. looks like upstream changed some macros though. | 16:30 |
| apw | rtg, this is aufs3 introducing a macro intersecting with upstream adding the 'get flags first' to avoid a use-after-free | 16:33 |
| apw | i'll build test my merge and see | 16:33 |
| rtg | apw, cool. I figured you would be able to spot it right away having done this before | 16:34 |
| apw | rtg, seems to work, i guess it makes sense for me to push this rebase so we don't have to do it again | 16:54 |
| rtg | apw, ack, thanks | 16:54 |
| apw | rtg, done | 16:54 |
| rtg | apw, I was thinking about uploading to the PPA so I could get some mileage on the IMA stuff | 16:54 |
| apw | i assume we'll get an -rc7 like tommorrow ? | 16:55 |
| Kano | i fixed the nvidia binary,but you should update the firmware package for 3.13 as well as files like /lib/firmware/radeon/HAWAII_pfp.bin are missing | 16:55 |
| rtg | apw, likely, but I'll be off skiing | 16:55 |
| Kano | maybe radeon dpm could be activated by default | 16:59 |
| apw | radeon dpm ? | 17:03 |
| apw | nvidia binary> patch? | 17:03 |
| Kano | apw: http://kanotix.com/files/fix/nvidia.wheezy/update/nvidia-graphics-drivers-331.20-2kanotix1/nvidia-graphics-drivers_331.20-2kanotix1.debian.tar.gz | 17:04 |
| Kano | look into debian/patches | 17:04 |
| rtg | it is tseliot that needs that info | 17:06 |
| Kano | and if somebody from X is looking, why dont you add libvdpau-dev for mesa | 17:06 |
| Kano | and package the vdpau /xvmc things | 17:06 |
| tseliot | these are questions you might want to ask in #ubuntu-x | 17:07 |
| Kano | well i dont use mesa from ubuntu, just as hint | 17:07 |
| tseliot | radeon dpm should be on by default in 3.14 | 17:07 |
| Kano | well why not with 3.13 | 17:08 |
| tseliot | additional fixes in 3.14, I guess | 17:08 |
| Kano | i used it with 3.12 too | 17:08 |
| tseliot | well, I use it here with 3.11 | 17:10 |
| kees | cking: so... your memory benchmark of IMA was for IMA built in, but not enabled? | 17:55 |
| cking | kees, I compared it with it build in and enabled vs not enabled with some simple instrumentation | 17:55 |
| kees | cking: the report in the bug was for which situation? | 17:57 |
| cking | built in and enabled | 17:57 |
| kees | I'm curious if just the CONFIG_IMA built in (but not enabled with policy) incurs a cost? | 17:57 |
| cking | with it built in and not enabled we see an atomic_t per inode | 17:57 |
| cking | extra | 17:57 |
| kees | ah, so the math following that was not the result of just the atomic_t? | 17:58 |
| kees | if it's just 8 bytes per inode when disabled, that seems like a reasonable cost to add CONFIG_IMA | 17:59 |
| cking | kees, yep, with it enabled there are some 72 byte slab allocations and misc meta data which again isn't too large | 17:59 |
| cking | per file | 17:59 |
| kees | cool. what's needed to enable it? (i.e. and how can we check if a system has it enabled or disabled?) | 18:00 |
| * cking rummages around for a suitable quickstart guide.. | 18:00 | |
| kees | I just want to make sure we don't regress -- CONFIG_IMA caused soooo much trouble for big file servers. :P | 18:01 |
| cking | kees, http://sourceforge.net/p/linux-ima/wiki/Home/ | 18:01 |
| cking | ^ i think that's more reasonable source of info rather than me regurgitating it all | 18:02 |
| kees | cking: sounds good. | 18:02 |
| kees | cking: thanks for doing all this! | 18:03 |
| cking | no probs, thank apw for asking me to look into it ;-) | 18:04 |
