| Specialist | there 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 |
| Specialist | then follows silence until i reboot, which is again indicated on the console: [ 1762.680197] Restarting system. | 00:01 |
| BenC | Specialist: are you sure there are actually kernel messages to be printed? | 00:03 |
| Specialist | yes, i can see them using dmesg | 00:03 |
| BenC | Perhaps the console level for kernel messages is set to mask them being sent to the console? | 00:03 |
| BenC | Is "quiet" on the kernel command line? | 00:03 |
| Specialist | BenC: no, quiet is not on the command line | 00:04 |
| BenC | Check printk level for console output then | 00:04 |
| BenC | Read and edit /etc/sysctl.d/10-console-messages.conf | 00:05 |
| Specialist | BenC: 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 |
| BenC | Specialist: http://www.makelinux.net/ldd3/chp-4-sect-2.shtml | 00:14 |
| BenC | Section 4.2.2 and the line above it where you "echo 8 > ..." | 00:14 |
| BenC | Specialist: So changing the values to 8 should do it | 00:15 |
| Specialist | thanks! | 00:15 |
| * BenC found that with google | 00:15 | |
| Specialist | BenC: just out of curiosity: what were your search terms? | 00:16 |
| BenC | linux kernel printk console level | 00:16 |

| fairuz | hi morning | 07:40 |
| fairuz | hi, 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 |
| ohsix | it just means you changed it | 07:42 |
| fairuz | ohsix: what do you mean by changed? afaik, if you do make clean, the dirty will go away | 07:44 |
| jjohansen | fairuz: do you have uncommitted changes? That can cause the dirty tag to be applied | 07:55 |
| fairuz | jjohansen: of course! why i dont think of that before | 07:55 |
| fairuz | jjohansen: what is the command to reset again (i tend to forget everything). something like git reset --hard master? | 07:57 |
| jjohansen | fairuz: to reset the head git reset --hard origin/master (if on the master branch) | 07:57 |
| jjohansen | fairuz: git checkout -f will throw away uncommitted changes | 07:57 |
| fairuz | jjohansen: cool, ty | 07:58 |
| fairuz | jjohansen: still bug hunting? | 08:15 |
| jjohansen | fairuz: not at the moment, but I do have several queued up | 08:15 |
| fairuz | jjohansen: i suppose it's very time consuming? Seen that you and DrDetroit did test a lot of kernels | 08:17 |
| jjohansen | fairuz: yeah it can be, it just depends on the bug | 08:17 |

| Specialist | hi 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 |
| jjohansen | Specialist: it can happen, some further ideas might be found at | 14:22 |
| jjohansen | https://wiki.ubuntu.com/DebuggingKernelSuspend | 14:22 |
| jjohansen | https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume | 14:22 |
| Specialist | jjohansen: 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 |
| jjohansen | Specialist: ugh, yeah usb keyboard making the flashing led trick less than useful | 14:27 |
| jjohansen | or less useful | 14:27 |
| Specialist | well, then it's time to resurrect my ps/2 keyboard ;-) | 14:28 |

| Specialist | yesterday 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 |
| ohsix | Specialist: theres actually in practice lots of places to store that information, but the rtc is the lowest common denominator | 14:50 |
| Specialist | ohsix: are you aware of any code sample that i may re-use? | 14:51 |
| ohsix | Specialist: don't know what you're doing, i just saw the rtc comment and something about debugging suspend | 14:55 |
| Specialist | ohsix: 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 phase | 14:57 |
| sconklin | ppisati: thanks for verifying your bug! | 14:59 |
| ohsix | Specialist: i used netconsole | 15:00 |
| Specialist | ohsix: 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 time | 15:02 |
| diwic | Specialist, 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 again | 15:02 |
| Specialist | ohsix: 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 code | 15:04 |
| fairuz | Hi, 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) modules | 15:12 |
| jjohansen | fairuz: O= | 15:16 |
| jjohansen | but its not just the output folder for the .ko its all object files | 15:16 |
| sforshee | fairuz, have you tried using using MOD_INSTALL_PATH with make modules_install ? | 15:18 |
| sforshee | e.g. 'MOD_INSTALL_PATH=/foo make modules_install' | 15:19 |
| fairuz | sforshee: I'm compiling __a__ module | 15:19 |
| fairuz | an external one | 15:19 |
| sforshee | fairuz, yes, but what does it do if you run that from your module's source dir? I don't know, but might be worth trying | 15:20 |
| fairuz | sforshee: it will install the modules from the source tree not my module :D | 15:21 |
| fairuz | jjohansen: already tried that before but no luck | 15:21 |
| sforshee | fairuz, that's too bad | 15:22 |
| jjohansen | fairuz: hrmm, it should work I know I have used it with external modules, mind you that was years ago | 15:22 |
| * ogasawara back in 20min | 15:26 | |
| fairuz | jjohansen: that's why..i wonder myself whhy it didn't work. | 15:28 |
| === sconklin is now known as sconklin-afk | ||
| sforshee | fairuz, I just tried it and it did work | 15:31 |
| fairuz | sforshee: what did you try? | 15:31 |
| sforshee | make -C /path/to/kernel M=$(pwd) INSTALL_MOD_PATH=/path/to/modules modules_install | 15:32 |
| sforshee | fairuz, that installed my module to /path/to/modules | 15:32 |
| fairuz | sforshee: it will install just the external module? and not the other kernel modules? | 15:33 |
| sforshee | fairuz, yes | 15:33 |
| sforshee | fairuz, note that if you use a relative path it will be relative to the kernel source directory, not your module source dir | 15:34 |
| fairuz | sforshee: it will just move the files or it will compile and move the files | 15:36 |
| jjohansen | fairuz: it should set the compiler to write the files to the target location | 15:37 |
| * jjohansen has used it in the past for source trees that were read only | 15:37 | |
| fairuz | I 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_install | 15:40 |
| sforshee | jjohansen, fairuz, just using the modules_install target didn't build for me, I had to do the modules target as well | 15:40 |
| fairuz | and it installs lib/modules directory in my target folder | 15:40 |
| fairuz | and no sign of my own modules | 15:40 |
| sforshee | fairuz, see my comment above, you'll have to do a 'make modules' first | 15:41 |
| sforshee | in my testing anyway | 15:41 |
| sforshee | and that will build to your local directory | 15:41 |
| sforshee | unless you use O=... | 15:41 |
| fairuz | sforshee: done that | 15:41 |
| sforshee | fairuz, don't know what to say, it installs my module | 15:43 |
| fairuz | sforshee: in your case, it did not install /lib/modules/kernel-name in your target folder? | 15:43 |
| sforshee | fairuz, no, it does create lib/modules/..., and installs the module there | 15:44 |
| fairuz | sforshee: ah ok i got what you mean | 15:44 |
| sforshee | fairuz, if you want something different I guess you could make a custom target in your local makefile | 15:44 |
| fairuz | sforshee: it puts the module in /lib/modules/kernel-name/extra/* | 15:45 |
| sforshee | fairuz, yes | 15:45 |
| fairuz | sforshee: hmm not really what i want actually.. | 15:46 |
| fairuz | I'm searching something like target-folder/mymodule.ko | 15:46 |
| sforshee | fairuz, that may be the only thing the kernel makefile provides | 15:47 |

| fairuz | sforshee: jjohansen: btw, thanks for helping | 15:48 |
| sforshee | fairuz, iirc O= puts all the build targets in that dir, which probably isn't what you want anyway | 15:48 |

| tgardner | ogasawara, great, thanks. | 16:18 |
| sforshee | tgardner, for the eeepc-wmi backports, is it best to base the branch for the pull request off of master-next ? | 16:19 |
| tgardner | sforshee, that works, but its not critical. | 16:19 |
| sforshee | tgardner, yeah, there probably aren't any differences between master and master-next for that file, I was just wondering | 16:20 |
| sforshee | thanks | 16:21 |
| tgardner | sforshee, 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 |

| bjf | ogasawara, the April 14 freeze date, is that when you'll upload or the last day we put changes into the repo ? | 18:56 |
| ogasawara | bjf: 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 14th | 18:57 |
| ogasawara | bjf: we can still apply changes, they'll just be subject to SRU | 18:57 |
| ogasawara | bjf: but there's no guarantee that those changes will warrant another upload | 18:57 |
| bjf | ogasawara, right, i'm just thinking that one way of thinking is that the code is actually frozen on the 12th | 18:58 |
