| ogasawara | rtg: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1338919 . Patch is referenced in comment #11. Do you want to wait till that hits 3.18 or queue it now before utopic kernel freeze so we don't have SRU paperwork. | 13:39 |

| ubot5 | Launchpad bug 1338919 in linux (Ubuntu) "[F06A]The information - CPU cores is incorrect in Ubuntu14.04 cpuinfo." [Medium,Triaged] | 13:39 |
| rtg | ogasawara, was just test building, then gonna run it on a couple of NUMA platforms | 13:40 |
| ogasawara | rtg: ack | 13:40 |
| rtg | ogasawara, its pushed to Utopic master-next | 13:40 |
| ogasawara | rtg: ah cool, I hadn't looked | 13:40 |
| rtg | ogasawara, seconds ago | 13:41 |
| ogasawara | jsalisbury: pending rtg's smoke testing in utopic, could you also crank out a Trusty test kernel with that patch too and work with catbus1 (ie Samantha) to reach out to her contacts for testing on Trusty. | 13:47 |
| ogasawara | jsalisbury: and we'll give you the honors of the Trusty SRU :) | 13:47 |
| jsalisbury | ogasawara, will do | 14:32 |
| ogasawara | rtg, apw: https://lkml.org/lkml/2014/9/26/568 | 14:36 |
| rtg | ogasawara, debian.master/config/config.common.ubuntu:# CONFIG_DMA_CMA is not set | 14:38 |
| rtg | we disabled it for both Trusty and Utopic | 14:38 |
| ogasawara | rtg: hrm, I see it on for Trusty | 14:40 |
| * ogasawara makes sure I'm in the right repo and branch | 14:40 | |
| rtg | me too | 14:40 |
| rtg | dang, you're right | 14:41 |
| ogasawara | rtg: but it does look like it is off in Utopic | 14:41 |
| ogasawara | even if the annotation file suggests otherwise | 14:41 |
| rtg | yup | 14:41 |
| rtg | ogasawara, fixed now | 14:42 |
| rtg | I'll SRU that config for trusty | 14:43 |
| ogasawara | rtg: ack, thanks | 14:43 |
| ogasawara | rtg: I'll respond to that thread as well | 14:43 |
| * apw notes rtg has this under control ... | 14:44 | |
| jsalisbury | ogasawara, rtg, there was a bug on CONFIG_DMA_CMA: bug 1362261 | 14:46 |
| ubot5 | bug 1362261 in linux (Ubuntu Trusty) "CONFIG_DMA_CMA causes ttm performance problems/hangs" [Medium,Incomplete] https://launchpad.net/bugs/1362261 | 14:46 |
| rtg | jsalisbury, thanks, I was just going to look for that | 14:46 |
| jsalisbury | rtg, I was going to do a Trusty SRU for that bug, but I didn't get definitive test results yet. | 14:49 |
| rtg | jsalisbury, It seems nobody has complained about Trusty. Now that I'm remembering this bug a little more, I'm not as inclined to change it for Trusty. | 14:50 |
| rtg | ogasawara, ^^ | 14:50 |
| ogasawara | rtg: ack | 14:51 |
| jsalisbury | rtg, yeah | 14:51 |
| rtg | I mean, it ain't broke, so lets not fix better. | 14:51 |
| rtg | fix it better* | 14:51 |
| ogasawara | jsalisbury: certainly based on the feedback, it does not seem to be impacting Trusty reporters of that bug | 14:51 |
| jsalisbury | ogasawara, agreed | 14:52 |
| ogasawara | rtg, jsalisbury: so reading that a little more, the guys not seeing issues on Trusty is with readeon, I wonder if it would manifest with other drivers | 15:00 |
| rtg | ogasawara, perhaps, but nobody is complaining regardless. | 15:01 |
| rtg | ogasawara, by the way, the patch for http://bugs.launchpad.net/bugs/1338919 appears to not have caused any regressions that I can see. | 15:03 |
| ubot5 | Launchpad bug 1338919 in linux (Ubuntu Utopic) "[F06A]The information - CPU cores is incorrect in Ubuntu14.04 cpuinfo." [Medium,Fix committed] | 15:03 |
| ogasawara | rtg: ack, thanks | 15:03 |
| jsalisbury | ogasawara, I didn't read through that entire LKML tread you mentioned. The bug is for a performance issue, is that what they are talking about on LKML as well? | 15:04 |
| ogasawara | jsalisbury: yep | 15:04 |
| jsalisbury | ahh, ok | 15:04 |
| jsalisbury | rtg, did you have any issue building the patch for bug 1338919 against Utopic? It failed to build against Trusty for me, but I'm digging into why | 15:49 |

| rtg | jsalisbury, nope, worked fine. clean cherry-pick | 15:50 |
| jsalisbury | rtg, ok, thanks. I'll dig as to why if failed | 15:50 |

| dirbaio | Hello | 22:49 |
| dirbaio | I'm building some kernels following the instructions here: | 22:49 |
| dirbaio | http://kernel-handbook.alioth.debian.org/ch-common-tasks.html | 22:49 |
| dirbaio | section 4.5 | 22:49 |
| dirbaio | Works fine, the resulting kernels install fine and boot | 22:49 |
| dirbaio | the problem is building the deb packages is horribly slow | 22:50 |
| dirbaio | much slower than compilation itself | 22:50 |
| dirbaio | it's been "building package linux-image..." for more than 20 minutes now | 22:50 |
| dirbaio | is this normal? Is there any trick to make it faster? | 22:50 |
| dirbaio | compilation takes around 15min for me | 22:51 |
| dirbaio | okay, turns out it's my fault | 23:37 |
| dirbaio | disabling DEBUG_INFO makes it reasonably fast now | 23:37 |
| dirbaio | still interested in ways of making it faster though :) | 23:37 |
| dirbaio | it boots | 23:41 |
| dirbaio | :D | 23:41 |
