=== BruceMa is now known as BruceMa-afk [10:37] cking: just reading about stress-ng. In CPU compute, can it generate %loading that is frequency invariant? IOW, 50% load at 2GHz != 50% load at 1GHz [10:40] amitk, it's not intelligent like that, it just breaks the load into time slices of idle and loaded, so it ignores the clock freq [10:41] cking: ok, we've modified cyclictest for that behaviour and are current modifying rt-app to do the same [10:42] cking: but the memory load might be interesting, I'll check it out [10:42] amitk, if you see any niches where I can add more stressors let me know, I'd like to make stress-ng more useful over time [10:45] cking: sure, I'll play around a bit. Our focus hasn't been finding the boundaries (stressing) but more about making it easy for sched maintainers to be able to simulate typical mobile (android) behaviour on a std. linux distro - e.g. mp3 playback, web browsing. [10:46] cking: but i can see stress-ng being useful to setup thermal constraints, for example [10:46] amitk, indeed, stress-ng was more like "how can I fully load a machine and see how much I can make the CPU and cache toasty" [10:46] and the old stress tool wasn't really useful enough for what I was playing with [10:47] mainly because I was also tinkering with thermald and I wanted to see if I could make that kick on a hot intel box [10:51] Hi [10:51] Dose someone know, when I am trying to compile Linux 3.14 kernel I get the following error : ERROR: modinfo: could not open /lib/modules/3.14.0/modules.dep [10:51] Why this error is coming ? I tried on Ubuntu and CentOS and on both I get almost similar error [10:52] Any clue on this issue will be helpful. === ara is now known as Guest7746 [13:27] apw, I pushed the rebase to 3.16-rc2. I guess we ought to start doing some testing this week. [13:38] rtg, yeah, it must be getting close, we should get it in the CKT PPA soon so jibel can test against it [13:38] apw, ah, right. I'll do that today. === shadeslayer_ is now known as shadeslayer [13:47] BenC, don't forget to give some love to powerpc64-emb [13:47] rtg: Right, on it, thanks [13:47] BenC, do you think you'll get it figured out this morning ? I'll wait on the first upload if so. [13:48] rtg: I’m hoping so. I’ll know more withing about 15-30 mins [13:48] BenC, cool, will wait for a bit then [13:50] rtg: This is a compile error, correct? [13:51] BenC, yup. [13:51] BenC, link error IIRC [13:51] rtg: Any chance you already have a log of the error? [13:52] BenC, hmm, probably not. all of my local build tests are fairly ephemeral. it wouldn't take but 10 minutes or so to recreate it. [13:53] rtg: I have a build started… [15:11] rtg: I have the fix…one-liner and only affects 85xx (freescale) === hatch__ is now known as hatch [15:13] BenC, cool, thats the best kind. I'll probably look at it and think, "Why couldn't I have figured that out ?" [15:15] rtg: The error you saw related to smp_(give|take)_timebase, correct? [15:15] *smp_generic_(give|take)_timebase [15:17] BenC, yup, thats the one [15:21] rtg: Patch sent to kernel-team [15:33] smb, hey ... we pulled a lot of VIRT* things =y is that still appropriate [15:35] apw, I would assume yes. At least as long as we want to have boot essentials in for virt and bare-metal at the same time. [15:35] apw, Of course you could ask me to do that part of the conf review. :) [15:36] smb, heh no as long as they are needed i am happy [15:38] apw, At least I am under the impression they were. Though things can silently change, so I would not want to bet money on it [15:39] smb: I'm willing to bet a lot of that stuff can be modular, but that requires more than just IRC handwaving. :P [15:39] Like, actual testing. On multiple arches. Ick. [15:40] infinity, A lot _can_ be modular. The problem with them was that (again at least at some point) there was nothing that would trigger them auto-load [15:40] smb: Well, being auto-loaded is implied in my "can be modular" statement. If something needs to be manually loaded, that's a no-go. [15:42] infinity, Ah ok. So yeah. Some may have changed but agreed, I neither would want things to change without very well tested well. [15:43] "very well tested well". [15:43] textual deja-vu [15:43] Or not remembering the word one typed a second ago
