=== ara_ is now known as ara [13:39] 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] Launchpad bug 1338919 in linux (Ubuntu) "[F06A]The information - CPU cores is incorrect in Ubuntu14.04 cpuinfo." [Medium,Triaged] [13:40] ogasawara, was just test building, then gonna run it on a couple of NUMA platforms [13:40] rtg: ack [13:40] ogasawara, its pushed to Utopic master-next [13:40] rtg: ah cool, I hadn't looked [13:41] ogasawara, seconds ago [13:47] 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] jsalisbury: and we'll give you the honors of the Trusty SRU :) [14:32] ogasawara, will do [14:36] rtg, apw: https://lkml.org/lkml/2014/9/26/568 [14:38] ogasawara, debian.master/config/config.common.ubuntu:# CONFIG_DMA_CMA is not set [14:38] we disabled it for both Trusty and Utopic [14:40] rtg: hrm, I see it on for Trusty [14:40] * ogasawara makes sure I'm in the right repo and branch [14:40] me too [14:41] dang, you're right [14:41] rtg: but it does look like it is off in Utopic [14:41] even if the annotation file suggests otherwise [14:41] yup [14:42] ogasawara, fixed now [14:43] I'll SRU that config for trusty [14:43] rtg: ack, thanks [14:43] rtg: I'll respond to that thread as well [14:44] * apw notes rtg has this under control ... [14:46] ogasawara, rtg, there was a bug on CONFIG_DMA_CMA: bug 1362261 [14:46] bug 1362261 in linux (Ubuntu Trusty) "CONFIG_DMA_CMA causes ttm performance problems/hangs" [Medium,Incomplete] https://launchpad.net/bugs/1362261 [14:46] jsalisbury, thanks, I was just going to look for that [14:49] rtg, I was going to do a Trusty SRU for that bug, but I didn't get definitive test results yet. [14:50] 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] ogasawara, ^^ [14:51] rtg: ack [14:51] rtg, yeah [14:51] I mean, it ain't broke, so lets not fix better. [14:51] fix it better* [14:51] jsalisbury: certainly based on the feedback, it does not seem to be impacting Trusty reporters of that bug [14:52] ogasawara, agreed [15:00] 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 [15:01] ogasawara, perhaps, but nobody is complaining regardless. [15:03] 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] Launchpad bug 1338919 in linux (Ubuntu Utopic) "[F06A]The information - CPU cores is incorrect in Ubuntu14.04 cpuinfo." [Medium,Fix committed] [15:03] rtg: ack, thanks [15:04] 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] jsalisbury: yep [15:04] ahh, ok [15:49] 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] bug 1338919 in linux (Ubuntu Utopic) "[F06A]The information - CPU cores is incorrect in Ubuntu14.04 cpuinfo." [Medium,Fix committed] https://launchpad.net/bugs/1338919 [15:50] jsalisbury, nope, worked fine. clean cherry-pick [15:50] rtg, ok, thanks. I'll dig as to why if failed [16:03] yay, my 11 year old son won a photo competition: https://www.facebook.com/buchancountrypark/photos/a.848046551895697.1073741846.247149068652118/848046645229021/?type=3&theater [16:05] cking, -EWRONGCHAN ? [16:05] yup [16:06] oops [16:06] but +WELLDONE :) === davmor2_ is now known as davmor2 [22:49] Hello [22:49] I'm building some kernels following the instructions here: [22:49] http://kernel-handbook.alioth.debian.org/ch-common-tasks.html [22:49] section 4.5 [22:49] Works fine, the resulting kernels install fine and boot [22:50] the problem is building the deb packages is horribly slow [22:50] much slower than compilation itself [22:50] it's been "building package linux-image..." for more than 20 minutes now [22:50] is this normal? Is there any trick to make it faster? [22:51] compilation takes around 15min for me [23:37] okay, turns out it's my fault [23:37] disabling DEBUG_INFO makes it reasonably fast now [23:37] still interested in ways of making it faster though :) [23:41] it boots [23:41] :D
