Cosmo`morning10:21
Cosmo`a brief question ...10:22
Cosmo`what's the actual difference between the mainline kernel and the linaro version?10:22
=== michaelh1 is now known as michaelh1|away
faboCosmo`: latest release is 3.0.4 release + 2 patches10:49
Cosmo`so these are patches that aren't in the mainline that someone from the linaro group has come up with10:50
Cosmo`to better support arm platforms10:50
Cosmo`right?10:50
faboCosmo`: the easiest way is to go through the git repo10:50
Cosmo`yes i'm doing this now, i've not used git before so it's taking a while to work it out10:50
Cosmo`i *think* i've got what i want now10:50
Cosmo`which is linaro kernel 2.6.38.710:50
faboCosmo`: it could be patches cherry-picked outside of Linaro10:50
Cosmo`so the difference is just that there's patches in the linaro kernels that aren't in the mainline kernels10:51
Cosmo`but may well eventually make it upstream into the mainline kernel10:51
faboCosmo`: that aren't in the mainline kernels *yet*. it's more precise, as everything we do is upstreamed.10:52
Cosmo`everything eh? i see10:53
faboCosmo`: git diff v3.0.4 linux-linaro-3.0-2011.09-0 should tdo the trick10:53
Cosmo`ah, i didn't know git could do that10:54
Cosmo`took me long enough to work out how to pull down a tag ...10:54
faboCosmo`: you can be interested by reading http://www.linaro.org/linaro-blog/2011/09/09/the-evolution-of-the-linaro-kernel/10:54
Cosmo`that is very interesting, thank you10:55
faboyou're welcome10:55
Cosmo`it10:55
Cosmo`i'm mainly just trying to get the correct version of the kernel that the arm-linux guys have used their patch with10:55
Cosmo`which, as far as i can tell, is linaro 2.6.38.710:55
amitkvingu: I'm trying to understand this sentence on the sched_mc wiki: Finally, a load balance will be tried between the busiest group and the cpu if the average load of the local group is below the domain one and if there is an obvious imbalance (more than imbalance_pct %) between these 2 groups.11:25

tusharbrsalveti: I could not find any listing under /dev/disk/by-uuid too ...12:02

rsalvetitusharb: have to look12:03
tusharbrsalveti: sure .. I will try to push the code to glo/people/tushar for you to have a look at the config file .. 12:04

tusharbrsalveti: yes .. right .. 12:04
tusharbrsalveti: it was just an experimental effort to boot ubuntu using the latest mainline kernel without any LT enablement patches ...12:05

pm215doko: slangasek does the ubuntu packaging for qemu12:30
dokopm215, does he? he's not with Linaro anymore12:30
pm215that's ok, the ubuntu package isn't a linaro output :-)12:31
dokopm215, as long as you have a fixed package in linaro-overlay ;-P12:31
pm215anyway, if this looks like a problem with configure and it's still present in 2011.09 then I'll have a look at it. if it's a packaging bug then slangasek is your man12:32
dokomost likely libraries have switched to a multiarch location, and the configure is explicitly scanning directories than letting the compiler doing it's job 12:33

rsalvetimabac: I can help on that, but would need to understand better the changes first12:41
mabacrsalveti, sure. I'll provide examples of the changes to the hwpack configs. there isn't that much to change12:42

davidgilukpm215: It's an 8 core with 16GB - we erm found it12:44

pm215if you could confirm that (a) 0.14.50-2011.06-0-0ubuntu1 fails (b) doing the one line configure fix corrects this, that would be interesting info to add to that bug report12:47
hrwdoko: any hint how to make gcc-linaro-cross check /usr/arm-linux-gnueabi/lib instead of /usr/lib/gcc-linaro/arm-linux-gnueabi/lib for libs? headers were easy - edit of cross-include.diff12:47
looldavidgiluk: There are various ways to pass parallel information to packaging; the way you used requires support in the packaging itself, which varies packgae by package12:48
rsalvetimabac: sure, that's fine :-)12:49
looldavidgiluk: However, you can try passing -j10 to dpkg-buildpackage or debuild to parallelize calls into debian/rules; this might break or not, depending on whether debian/rules is correctly written or not, but it doesn't need explicit support by the package12:49

Cosmo`so16:44
Cosmo`pm215 ... I have done a lot of interesting stuff today16:44
Cosmo`i've stepped through the linux booting with the ICE enough to work out that the mmu is initialising properly and getting happily out of the compressed code16:45
pm215that's a good start16:45
Cosmo`and it's actually getting to the calls of printk that show varous things16:45
Cosmo`so i'm assuming it means that the console device is knacked16:45
Cosmo`but i'm not sure how to go about fixing that16:45
Cosmo`i've learnt more today than any other day for a LONG time16:46
pm215console is one of the things most likely to work because just about everybody uses it16:46
pm215so it's almost certainly either (a) you didn't configure the serial driver in or (b) command line argument to set console not right16:46
Cosmo`this is interesting16:46
Cosmo`because i'm using the same config as a working kernel16:46
pm215command line then, maybe16:46
Cosmo`and the command line args are the same as for the working kernel16:46
Cosmo`using ttyAMA016:46
Cosmo`we tried stepping through the execution of printk but it just becomes too complicated at that point16:47
pm215the trick with printk is not to actually wade through the middle of it: if you put a breakpoint at __call_console_drivers() you can find out whether there's actually any consoles in the kernel's list and if so where it is16:49
Cosmo`right ...16:50
Cosmo`i seem to recall trying that and it not hitting it16:50
Cosmo`BUT16:50
Cosmo`that might have been because i set the breakpoint before the MMU was setup16:50
Cosmo`so i think that knacks the breakpoints16:50
Cosmo`or at least it did something along those lines16:50
tgall_fooGRRRRR ... nothing like burning an hour trying to find a bug that turned out to be nothing more than a spelling error16:55
Cosmo`now i remember what i was confused pm21517:04
Cosmo`i did set a breakpoint for __call_console_drivers17:04
Cosmo`but it never hit it17:04
pm215Cosmo`: register_console() is another good place to breakpoint17:07
Cosmo`i see17:07

pm215Cosmo`: do you have CONFIG_EARLY_PRINTK set?17:18
Cosmo`i don't know, i'll look17:22
Cosmo`no, apparently not17:23
Cosmo`looks like it not mentioned in my config at all, pm21517:25
pm215it's in the config for the linux-arm.org kernel17:25
pm215if you don't have that then it's rather further on in the boot process before printk actually gets sent to the console, so a crash before that point looks like no-output17:26
Cosmo`at the moment i'm testing just a linaro kernel17:26
Cosmo`because17:26
Cosmo`they both seem to show the same output17:26
Cosmo`just using realview-smp_makedefconfig17:27
Cosmo`i could build another image using the patch against 2.6.38 and then run that through the ICE and see what's going on17:30
Cosmo`might show some more stuff17:30
pm215you really want early printk if you don't have it enabled in configure and on your command line.17:31
Cosmo`what's the command line option for early printk?17:32
Cosmo`as i'll enable it in the config17:32
pm215Cosmo`: I think you can just say 'earlyprintk'17:33
Cosmo`it looks like it has to be17:33
Cosmo`earlyprintk=ttySn[,baudrate]17:34
pfefferz_tgall_foo, pong17:35
pm215that's x86; the arm version ignores all its parameters17:35
Cosmo`ah, i see17:35
Cosmo`thank you17:35

tgall_foopfefferz_, on android, auxv is present right ?17:38
pfefferz_not sure17:38
pfefferz_I don't know what auxv is17:39
tgall_foo how about this .. on one of your android boxen ls /proc/self/auxv17:39
pfefferz_one sec, need to program a build17:40
Cosmo`oh17:50
Cosmo`my17:50
Cosmo`god17:50
Cosmo`the amount of output with earlyprintk17:50
Cosmo`however this is good17:50
pm215oh, you get some console output now? cool17:51
Cosmo`loads17:51
Cosmo`because there's loads of exceptions17:51
Cosmo`but at least i'm seeing them niow17:51
pm215Hmm. stick it into pastebin and post a url?17:51
Cosmo`i can digest17:51
Cosmo`as they all seem to be the same17:52
pm215pastebin would be best17:52
Cosmo`Internal error: 801 [#8] PREEMPT SMP17:52
Cosmo`over and over and over17:52
steev_are the freescale linaro kernel guys about?17:54
janimosteev, they may be sleeping already, I think most are in China17:55
janimoericm_, ^ ?17:55
steev_ah, okay :(17:55
janimosteev, what is your question btw?17:55
steev_i just wanted to find out what it will take to get the ipu driver into mainline.  i know shaun was working on devicetree support, but now he's working on mx6, so not sure what the status of things are17:56
janimojcrigby, around? We'd need to enable the EXT4 huge file support config thingy that prevents booting ext4fs in the 2.6.38 mx5 kernel in oneiric17:56
pfefferz_tgall_foo, ls /proc/self/auxv17:56
pfefferz_produces /proc/self/auxv  17:56
pm215Cosmo`: no, really, I'd like to see more output than that. (haven't seen that message before, but it's always much easier to guess what's going on when you have more context for error messages)17:57
tgall_foopfefferz_, excellent, thanks!17:57
janimoI'd gladly do the work - I have the tree checked out, but I am afraid I'd need some more guidance. The packaging a tree does not have info about workflow for adding new changes.17:57
pfefferz_np17:57
Cosmo`right pm215, give me a second17:58
janimojcrigby, I see you have consistent changelog entries generated by a template and probably a sequence of steps before  uploading. And probably want to keep your git tree in sync with the package17:58
steev_janimo: that info would be nice as we've been told to use the linaro kernel as well17:58
janimosteev, this is what  I use now https://wiki.linaro.org/Resources/HowTo/PackageYourOwnKernel17:59
janimoit is helpful but there are aspects not covered there17:59
janimosteev, no idea about your ipu driver  question, sorry17:59
Cosmo`here you go pm215 17:59

c10udhello, i'm using linaro 11.08 with Linux linaro-desktop 2.6.38-1000-linaro-lt-mx5 #8-Ubuntu Tue Aug 16 15:08:35 UTC 2011 armv7l armv7l armv7l GNU/Linux -- I'm doing some stuff through USB (capturing pics with custom program and lib) and i see memory usage is increasing each time i snap a pic of ~3MiB. Monitoring the situation with top i see my program's memory isn't growing (nor others). Could it be a leak in the kernel?18:00
steev_janimo: oh i didn't think you would, just wanting more info on the status of things18:00
pfefferz_rsalveti, which tree are you using for 4460?18:03
rsalvetipfefferz_: tilt, but I'm still fixing it18:03
rsalvetineed fixes at u-boot and kernel18:03
Cosmo`i think pm215 it's got to be something to do with the cross compiler suite i'm using18:03
pfefferz_would you send me the exact git/branch/config?18:04
Cosmo`i'm just using the latest one from codesourcery18:04
rsalvetipfefferz_: sure, after I get it working here18:04
pfefferz_rsalveti, actually I'm just collecting some data18:04
pfefferz_rsalveti, I want to see what are all the things we need to compose the Android version of it18:05
pfefferz_so everyone can get on the same page18:05
rsalvetipfefferz_: sure18:05
pfefferz_rsalveti, I think it may be as easy as,18:05
pm215Cosmo`: ah. the interesting bit here is "Unhandled fault: alignment exception" -- the kernel is trying to do an unaligned access which the hardware is faulting18:05
pfefferz_...not the right word...18:06
Cosmo`you know i think this is a problem with the latest codesourcery crosscompiler suites18:06
pfefferz_anyway...I'm just trying to get some clarity18:06
Cosmo`as i've just found an excerpt from a mailing list with someone having the same problem with the same toolset i'm using18:06
Cosmo`he;s identified an old version which works18:06
Cosmo`so i'll try that and report back18:06
pm215Cosmo`: you should make sure the combination of your kernel config and the compiler are telling it to generate code for armv618:06
pm215(ie not armv7)18:07
Cosmo`yes, it 'should' be fine18:07
Cosmo`as the config seems correct18:07
Cosmo`let me try the other toolchain and then i'll look further into the arm7/arm6 conundrum18:07
Cosmo`thanks for your help :)18:07
pm215you can probably add -mno-unaligned-access to your CFLAGS for the kernel build18:09
Cosmo`i'll do that18:09
Cosmo`does that sit in the main toplevel Makefile?18:09
Cosmo`oh god, i should really stop, i need to go home18:10
Cosmo`but there's always one more thing to do ...18:10
Cosmo`my brain is so fried18:10
pm215I think you can just say 'make [....] CFLAGS=-mno-unaligned-access' but I could be wrong18:12
pm215anyway, that's a workaround, but we should figure out who's actually right/wrong here, the kernel or the compiler18:12
Cosmo`k18:12
Cosmo`sec18:12
pm215if you say 'make [...] CFLAGS=...  V=1' it will print the actual gcc commands as it runs them18:13
Cosmo`ok, fresh uImage coming for the old version of the toolchain18:13
pm215google suggests maybe EXTRA_CFLAGS=-mno-unaligned-access actually18:14
Cosmo`i'll see how this uImage fares18:15
pm215http://comments.gmane.org/gmane.linux.ports.arm.kernel/117863 # looks like the kernel folk are aware of it, so for the moment the EXTRA_CFLAGS will do if you're compiling an older kernel with this toolchian18:20
Cosmo`today has been fun anyway18:20
Cosmo`this is the sort of crap i wanted to be doing when i started my PhD, heh18:20
mruoh, you've hit *that* bug18:21
Cosmo`SUCCESS18:22
=== prpplague_afk is now known as prpplague
Cosmo`you realise mru, that that phrase sums up my entire day18:23
mrusee also http://article.gmane.org/gmane.linux.ports.arm.kernel/13164318:25
Cosmo`well, thank you very much18:26
Cosmo`this all could have been avoided if i'd looked in the right place18:26
Cosmo`but it's been worth it, i've learnt a huge amount about how the linux kernel works today, and also got the ICE working18:26
mruthis is of course all russel king's fault18:27
mrufor insisting on *turning on* strict alignment checking18:27
Cosmo`i'm lost as to the specifics of why this broken right now18:27
Cosmo`but i'll look at it tomorrow18:27
Cosmo`right now i seriously need to go home and have a bath18:27
Cosmo`my brain feels like it's about to melt out of my ears18:27
mruit fails because some gcc versions (cleverly) emit unaligned loads and stores if the target cpu supports them18:28
mruand rmk refuses to flip one bit in a control register18:28
Cosmo`right ...18:28
Cosmo`i'll read it tomorrow and work it out18:29
Cosmo`what does rmk maintain?18:29
mrucore arm support18:29
mrusadly18:29
Cosmo`it looked to me like all the arm linux stuff was pretty deprecated18:29
Cosmo`i mean the toolchains from his site are ... so old18:29
mruyes18:29
mruhe is stuck in the armv5 era18:30
Cosmo`the latest post on his website it from 200818:30
Cosmo` is18:30
