[00:59] <furkan> hi, i'm just trying to test a regression before submitting a bug report for 3.19.0-12, but i can't seem to download 3.19.0-10 any longer via apt-get - any advice?
[01:00] <furkan> the problem is basically that dpms no longer works - it still works on mainline 4.0 rc7, and it used to work on the vivid 3.19 kernel, so it's definitely an update that broke it, but i just don't know which one
[01:01] <furkan> on 4.0 rc7 it also stops working after suspend/resume, which is how it was originally with vivid's 3.19, but now it doesn't work at all, even after a fresh boot
[02:03] <tmpRAOF> furkan: You can get it from launchpad directly.
[02:04] <RAOF> furkan: Start at https://launchpad.net/ubuntu/vivid/+source/linux and work through the “releases in ubuntu” links.
[02:23] <furkan> thanks RAOF i'll work through those when i get the chance
[13:18] <rtg> henrix, what are those CVE numbers so I can get them in the commit log ?
[13:18] <henrix> rtg: CVE-2015-2666: f84598bd7c851f8b0bf8cd0d7c3be0d73c432ff4; CVE-2015-2922: 6fd99094de2b83d1d4c8457f2c83483b2828e75a                                                                 
[13:18] <rtg> henrix, thanks
[13:19] <henrix> rtg: i can also give you the bug # in a min...
[13:19] <henrix> for CVE-2015-2922: bug #1441103
[13:20] <henrix> and bug #1438504
[13:22] <rtg> henrix, done
[13:22] <henrix> rtg: cool, thanks
[18:44] <mssbrg> Hi, I'm doing some testing with thunderbolt on a 14.10 machine, kernel 3.17.8 and I'm experiencing some odd behavior. When I connect my machine to a thunderbolt display, the display works, however there is no thunderbolt driver loaded. Any help?
[18:44] <mssbrg> I'm really just curious how this is happening
[18:45] <apw> mssbrg, well the display is probabally exposed using another driver, and the bus itself is builtin
[18:45] <apw> so you don't necessarily expect to see a driver for the bus enumerator
[18:46] <mssbrg> i would expect to see `thunderbolt` in lsmod, no?
[18:48] <mjg59> No
[18:48] <mjg59> Unless it's an Apple
[18:48] <mssbrg> this is all apple hardware
[18:49] <mjg59> And also still no unless you're running 3.19
[18:49] <mssbrg> apw: also, i don't really follow what you mean by display exposed using another driver/bus is builtin
[18:50] <mssbrg> mjg59: why is that?
[18:50] <mjg59> mssbrg: The Thunderbolt hardware isn't exposed to the OS until we start pretending to be Darwin
[18:51] <mjg59> The hardware itself will handle the displayport layering setup
[18:52] <mssbrg> by hardware, do you mean the intel thunderbolt controller? then what kind of interface is exported to the OS?
[18:56] <mjg59> It just looks like Displayport to the OS
[19:00] <mssbrg> mjg59: so if I upgrade to 3.19 can I expect to see a thunderbolt driver?
[19:06] <mjg59> mssbrg: Yes
[19:08] <mssbrg> mjg59: also, should I currently expect to see a displayport driver in lsmod?
[19:08] <mjg59> No
[19:08] <mjg59> That's handled by the individual graphics drivers and the drm core
[19:10] <mssbrg> ah interesting. but there is /some/ driver in lsmod I should see that is handling the display, right?
[19:10] <mjg59> Yeah, either nouveau or i915
[19:10] <mssbrg> ok cool, i see i915
[19:12] <mssbrg> mjg59: and so in 3.19, I would potentially see thunderbolt instead of i915?
[19:13] <mjg59> mssbrg: No, as well as
[19:13] <mjg59> The thunderbolt driver handles the PCIe hotplug part of Thunderbolt (on Apple - on other systems it's managed by the firmware)
[19:15] <mssbrg> ah ok
[19:16] <mssbrg> unrelated, but are there logs for this channel anywhere?
[19:28] <mssbrg> mjg59: out of curiousity, if I plugged in a non-display thunderbolt device would things be different? still no thunderbolt driver in lsmod?
[19:28] <mjg59> On that kernel? Yeah, and also it wouldn't work.
[19:29] <mssbrg> oh. i thought 3.17 was the first to support thunderbolt
[19:30] <apw> mssbrg, yes this is logged, erm
[19:31] <mjg59> mssbrg: Kind of
[19:31] <mssbrg> apw: are they available? I don't see a url in the topic.
[19:31] <mjg59> It'll work if there's a Thunderbolt device plugged in at boot
[19:31] <mjg59> And it'll stop working if you suspend
[19:31] <apw> http://irclogs.ubuntu.com/2015/04/08/%23ubuntu-kernel.html
[19:32] <apw> mssbrg, ^ they are logged in the same place as "all" ubuntu channels
[19:32] <mssbrg> apw: ty
[19:34] <mssbrg> mjg59: so if I understand correctly, the driver itself only implements the low level pcie communications, and the actual functionality of whatever device is always implemented by another driver?
[19:34] <mjg59> Yes
[20:09] <mssbrg> mjg59: hm, still no thunderbolt driver in lsmod in 3.19. hotplug also doesn't work, even with it manually loaded in. any thoughts?
[20:09] <mjg59> mssbrg: Huh. That surprises me. I'm afraid I don't have time to look at it right now, though
[20:11] <mssbrg> No problem! Any recommendations on anything to try on my own? Either way, thanks for all the help!
[23:19] <RAOF> Oh, that's right. Attempting to restart this box will hang because btrfs has blown up.
[23:21] <RAOF> Damn you, cking, for asking me to test that! :)
