Specialistthere must be something i am mising. everything is set up as per the tutorials i read, but still the last kernel message that ends up on the serial console is:00:00
Specialist[   27.571317] EXT4-fs (dm-2): mounted filesystem without journal. Opts: (null)00:00
Specialistthen follows silence until i reboot, which is again indicated on the console: [ 1762.680197] Restarting system.00:01
BenCSpecialist: are you sure there are actually kernel messages to be printed?00:03
Specialistyes, i can see them using dmesg00:03
BenCPerhaps the console level for kernel messages is set to mask them being sent to the console?00:03
BenCIs "quiet" on the kernel command line?00:03
SpecialistBenC: no, quiet is not on the command line00:04
BenCCheck printk level for console output then00:04
BenCRead and edit /etc/sysctl.d/10-console-messages.conf00:05
SpecialistBenC: it's 4 4 1 7 - what would i need to specify if i wanted to see all messages (googling did not help to figure this out - most hits just list the defaults)00:13
BenCSpecialist: http://www.makelinux.net/ldd3/chp-4-sect-2.shtml00:14
BenCSection 4.2.2 and the line above it where you "echo 8 > ..."00:14
BenCSpecialist: So changing the values to 8 should do it00:15
* BenC found that with google00:15

fairuzhi morning07:40
fairuzhi, is it a problem if i got a compiled kernel with -dirty behind it's name? I already did make clean but no luck, still it adds -dirty.07:42
ohsixit just means you changed it07:42
fairuzohsix: what do you mean by changed? afaik, if you do make clean, the dirty will go away07:44
jjohansenfairuz: do you have uncommitted changes?  That can cause the dirty tag to be applied07:55
fairuzjjohansen: of course! why i dont think of that before07:55
fairuzjjohansen: what is the command to reset again (i tend to forget everything). something like git reset --hard master?07:57
jjohansenfairuz: to reset the head git reset --hard origin/master (if on the master branch)07:57
jjohansenfairuz: git checkout -f will throw away uncommitted changes07:57
fairuzjjohansen: cool, ty07:58
fairuzjjohansen: still bug hunting?08:15
jjohansenfairuz: not at the moment, but I do have several queued up08:15

Specialisthi there, my struggle to figure out what is breaking s2ram for my machine on 2.6.38 continues. i got a serial console working. unfortunately, during suspend the serial console output changes to garbage (with no_console_suspend enabled) rather early during the suspend phase so that i cannot read the most interesting information. is this to be expected?14:10
jjohansenSpecialist: it can happen, some further ideas might be found at14:22
Specialistjjohansen: thanks! i have to say that i have read those documents already a couple of times ;-) the only untested hypothesis that remains is the possibility of a kernel panic during suspend. i guess a usb keyboard will not indicate that event by flashing the keyboard led as usb will probably already be down, right?14:26
jjohansenSpecialist: ugh, yeah usb keyboard making the flashing led trick less than useful14:27
jjohansenor less useful14:27
Specialistwell, then it's time to resurrect my ps/2 keyboard ;-)14:28

Specialistyesterday someone also mentioned storing debug information in the cmos using the rtc. instead of using the current time (causing the information to decay) wouldn't it make sense to set a (disabled) alarm with the intended payload instead? that data should not decay...14:49
ohsixSpecialist: theres actually in practice lots of places to store that information, but the rtc is the lowest common denominator14:50
Specialistohsix: are you aware of any code sample that i may re-use?14:51
ohsixSpecialist: don't know what you're doing, i just saw the rtc comment and something about debugging suspend14:55
Specialistohsix: i am trying to figure out why my system sporadically freezes during s2ram. i alreadt tried serial console, but that becomes corrupted during suspend. so i thought that i'd modify the rtc state using a bitmask to record certain checkpoint information during the suspend phase14:57
sconklinppisati: thanks for verifying your bug!14:59
ohsixSpecialist: i used netconsole15:00
Specialistohsix: the thing is that for me the suspend fails so low-level that the rtc may be the only device that will still work reliably at that time15:02
diwicSpecialist, I think the kernel uses the upper bits only and you have a few minutes only to read the information out of the rtc when you boot up again15:02
Specialistohsix: well, that's ok for me. i just spotted the implementation in drivers/base/power/trace.c, which seems like a good starting point for my debug code15:04
fairuzHi, when compiling a external module, can I specify the output folder for *.ko file? I use this right now to compile : make ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) -C $(KERNEL_SRC) M=$(PWD) modules15:12
jjohansenfairuz: O=15:16
jjohansenbut its not just the output folder for the .ko its all object files15:16
sforsheefairuz, have you tried using using MOD_INSTALL_PATH with make modules_install ?15:18
sforsheee.g. 'MOD_INSTALL_PATH=/foo make modules_install'15:19
fairuzsforshee: I'm compiling __a__ module15:19
fairuzan external one15:19
sforsheefairuz, yes, but what does it do if you run that from your module's source dir? I don't know, but might be worth trying15:20
fairuzsforshee: it will install the modules from the source tree not my module :D15:21
fairuzjjohansen: already tried that before but no luck15:21
sforsheefairuz, that's too bad15:22
jjohansenfairuz: hrmm, it should work I know I have used it with external modules, mind you that was years ago15:22
* ogasawara back in 20min15:26
fairuzjjohansen: that's why..i wonder myself whhy it didn't work.15:28
=== sconklin is now known as sconklin-afk
sforsheefairuz, I just tried it and it did work15:31
fairuzsforshee: what did you try?15:31
sforsheemake -C /path/to/kernel M=$(pwd) INSTALL_MOD_PATH=/path/to/modules modules_install15:32
sforsheefairuz, that installed my module to /path/to/modules15:32
fairuzsforshee: it will install just the external module? and not the other kernel modules?15:33
sforsheefairuz, yes15:33
sforsheefairuz, note that if you use a relative path it will be relative to the kernel source directory, not your module source dir15:34
fairuzsforshee: it will just move the files or it will compile and move the files15:36
jjohansenfairuz: it should set the compiler to write the files to the target location15:37
* jjohansen has used it in the past for source trees that were read only15:37
fairuzI use this -> make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- -C /home/x0152532/kernel-src M=/home/x0152532/remote-x0152532/tools/caches/pl310 INSTALL_MOD_PATH=/home/x0152532/remote-x0152532/tools/caches/pl310/bin modules_install15:40
sforsheejjohansen, fairuz, just using the modules_install target didn't build for me, I had to do the modules target as well15:40
fairuzand it installs lib/modules directory in my target folder15:40
fairuzand no sign of my own modules15:40
sforsheefairuz, see my comment above, you'll have to do a 'make modules' first15:41
sforsheein my testing anyway15:41
sforsheeand that will build to your local directory15:41
sforsheeunless you use O=...15:41
fairuzsforshee: done that15:41
sforsheefairuz, don't know what to say, it installs my module15:43
fairuzsforshee: in your case, it did not install /lib/modules/kernel-name in your target folder?15:43
sforsheefairuz, no, it does create lib/modules/..., and installs the module there15:44
fairuzsforshee: ah ok i got what you mean15:44
sforsheefairuz, if you want something different I guess you could make a custom target in your local makefile15:44
fairuzsforshee: it puts the module in /lib/modules/kernel-name/extra/*15:45
sforsheefairuz, yes15:45
fairuzsforshee: hmm not really what i want actually.. 15:46
fairuzI'm searching something like target-folder/mymodule.ko15:46
sforsheefairuz, that may be the only thing the kernel makefile provides15:47

tgardnerogasawara, great, thanks.16:18
sforsheetgardner, for the eeepc-wmi backports, is it best to base the branch for the pull request off of master-next ?16:19
tgardnersforshee, that works, but its not critical.16:19
sforsheetgardner, yeah, there probably aren't any differences between master and master-next for that file, I was just wondering16:20
tgardnersforshee, the advantage of using master is that it gives you a stable merge point, whereas master-next often gets rebased. however, small pull requests aren't that hard to figure out.16:21

bjfogasawara, the April 14 freeze date, is that when you'll upload or the last day we put changes into the repo ?18:56
ogasawarabjf: ideally, we'll make no changes to the kernel past that date, which means we'd have to upload ~2days prior for the builds to finish by the 14th18:57
ogasawarabjf: we can still apply changes, they'll just be subject to SRU18:57
ogasawarabjf:  but there's no guarantee that those changes will warrant another upload18:57
bjfogasawara, right, i'm just thinking that one way of thinking is that the code is actually frozen on the 12th18:58
