Sep 28 05:19:48 <builder> build #298 of ep93xx is complete: Failure [failed compile_5]  Build details are at http://buildbot.openwrt.org:8010/builders/ep93xx/builds/298
Sep 28 05:23:10 <OpenWrt-Commits> nbd r38247 trunk/package/kernel/linux/modules/other.mk
Sep 28 05:23:10 <OpenWrt-Commits> kernel: disable kmod-iio for linux 3.6 as well (to avoid build issues due to missing config symbol changes)
Sep 28 05:27:17 <eigma> I'm trying to compile the ag71xx ethernet driver as a module and finding that it causes "VFS: Cannot open root device" errors.. any clues how these may be related?
Sep 28 05:29:29 <nbd> eigma: it's highly unlikely that the ethernet driver change caused this, you probably messed up something else
Sep 28 05:29:58 <nbd> eigma: but without further information (e.g. a boot log), there's no way to figure out what went wrong
Sep 28 05:29:58 <eigma> hmm
Sep 28 05:30:05 <eigma> I can post a boot log, one sec
Sep 28 05:30:18 <eigma> actually I narrowed it down to the MDIO driver
Sep 28 05:30:30 <eigma> ag71xx_main actually registers two platform drivers
Sep 28 05:30:39 <eigma> the ethernet driver itself and MDIO
Sep 28 05:30:46 <nbd> neither of which is relevant for filesystem stuff
Sep 28 05:30:59 <eigma> ok, I will post boot logs, one sec
Sep 28 05:41:31 <eigma> sorry, my dev cycle is a bit long
Sep 28 05:45:09 <eigma> is there a make target that will rebuild kernel, modules and rootfs, but nothing else?
Sep 28 05:46:40 <nbd> make target/compile package/linux/compile package/install target/install
Sep 28 05:47:39 <eigma> this takes into account changes in target/linux/ar71xx/files?
Sep 28 05:47:59 <nbd> no
Sep 28 05:48:14 <nbd> but you can edit stuff in the kernel build tree
Sep 28 05:48:17 <nbd> then you can just run make
Sep 28 05:48:22 <nbd> and it won't have to rebuild everything
Sep 28 05:48:42 <eigma> I would like to keep it in git somehow, so i can track exactly what I've changed
Sep 28 05:49:07 <nbd> you could copy target/linux/ar71xx/files/ to the kernel build tree before running make
Sep 28 05:49:26 <eigma> k
Sep 28 05:50:35 <eigma> a few links..
Sep 28 05:50:37 <eigma> tree: https://github.com/cpatulea/openwrt/tree/c6b97ec7fa7b1f4e93da116a069853b92e94ad9c
Sep 28 05:50:53 <eigma> .config: http://pastebin.com/gbqMAmRg
Sep 28 05:51:17 <eigma> boot log: http://pastebin.com/3gH5HD60
Sep 28 05:51:27 <eigma> this is the working version, with ag71xx in-kernel
Sep 28 05:52:14 <eigma> next, I will build from cly branch HEAD (just 1 commit ahead)
Sep 28 05:56:21 <eigma> boot log: http://pastebin.com/kWCXw683
Sep 28 05:57:44 <nbd> i'm not going to go through that tree and look for possibly related changes
Sep 28 05:58:22 <eigma> it's not much, I can show you a diffstat
Sep 28 05:59:02 <nbd> a full diff would be more useful
Sep 28 05:59:18 <eigma> ok
Sep 28 05:59:18 <nbd> a full diff between plain openwrt and whatever it is you're using
Sep 28 05:59:59 <eigma> I've made my own changes and merged from upstream at different points in time, so there's not a clear version to diff against
Sep 28 06:00:07 <eigma> let me try to get as clean a diff as I can, one sec
Sep 28 06:02:27 <eigma> against 299e650: http://sprunge.us/MEUB
Sep 28 06:02:56 <eigma> it's a little old, but I think it should be ok?
Sep 28 06:05:35 <nbd> and you're absolutely sure that this is all of it?
Sep 28 06:06:46 <eigma> I'm pretty sure.. what can I do to double-check?
Sep 28 06:07:19 <eigma> I have a few untracked files but they shouldn't interfere.. http://sprunge.us/dEAP
Sep 28 06:07:44 <eigma> I have some things in files/
Sep 28 06:08:13 <eigma> but again I don't see a problem: http://sprunge.us/VKEj
Sep 28 06:08:49 <eigma> I find it interesting that the MTD partition listing is mixed up with other inits
Sep 28 06:08:54 <eigma> in the boot log
Sep 28 06:09:02 <eigma> do you know if these run in parallel?
Sep 28 06:09:44 <nbd> no idea
Sep 28 06:09:53 <eigma> I just realized the partition listing doesn't even finish for the broken case
Sep 28 06:10:40 <eigma> actually the only reason I'm doing this is netconsole doesn't seem to work well through AR8316
Sep 28 06:10:51 <eigma> so I'd like to build the net drivers as modules so I can hack on them more easily
Sep 28 06:11:07 <eigma> maybe there's some better way to do this?
Sep 28 06:19:05 <eigma> something's happening in a different order
Sep 28 06:19:31 <eigma> "Creating 5 MTD partitions" and "NET: Registered protocol family 17" are swapped
Sep 28 06:19:54 <eigma> a few others as well
Sep 28 06:20:23 <eigma> is there an easy way to print the stack in kernel?
Sep 28 06:22:30 <nbd> dump_stack()
Sep 28 06:23:30 <eigma> do you have a debugging rig?
Sep 28 06:28:16 <nbd> ?
Sep 28 06:32:33 <eigma> an in-circuit debugger for your hardware
Sep 28 06:32:50 <nbd> i do most debugging with printk
Sep 28 06:33:13 <nbd> if there's something where the hardware locks up or really weird stuff happens where i need to inspect the state, i use jtag
Sep 28 06:35:11 <Devastator> nbd do you work with hardware development as well or only driver/software?
Sep 28 06:35:21 <nbd> only driver/software
Sep 28 06:35:53 <Devastator> "only" hehe
Sep 28 06:36:11 <nbd> at some point i'll probably take some time to learn more about hw stuff as well
Sep 28 06:36:41 <Devastator> qualcomm should hire you, if they didn't already
Sep 28 06:37:02 <nbd> they tried to
Sep 28 06:37:08 <nbd> but i don't want to work full time for a big company
Sep 28 06:37:50 <Devastator> fund your own company
Sep 28 06:38:04 <Devastator> Fietkau Co.,
Sep 28 06:38:07 <nbd> i'm already working just like i want to
Sep 28 06:38:28 <nbd> choosing my own projects (based on fun, not money)
Sep 28 06:38:34 <eigma> is it contracts?
Sep 28 06:38:53 <nbd> sometimes contracts, sometimes other things
Sep 28 06:39:02 <Devastator> yeah, that's how I want to live
Sep 28 06:39:10 <Devastator> puzzles, fun puzzles
Sep 28 06:40:12 <eigma> how long have you been doing this?
Sep 28 06:40:31 <nbd> let's just say, i never had a normal job
Sep 28 06:40:34 <nbd> in my entire life
Sep 28 06:41:10 <nbd> i've been doing openwrt as a hobby since around 2004
Sep 28 06:41:28 <nbd> and gradually started getting paid for it
Sep 28 06:41:33 <nbd> until it became my main source of income
Sep 28 06:42:19 <eigma> that's cool
Sep 28 06:42:48 <Devastator> either I'm dumb for a major or too smart
Sep 28 06:42:50 <eigma> I would like that kind of job.. I think :)
Sep 28 06:43:01 <Devastator> I can't get a college degree :/
Sep 28 06:43:10 <nbd> i didn't get mine either
Sep 28 06:43:25 <nbd> at some point i decided that my projects are more important than my degree
Sep 28 06:43:32 <Devastator> and you are doing just fine
Sep 28 06:43:39 <Devastator> you give me hope..
Sep 28 06:43:58 <nbd> a degree matters for getting jobs in many big (and sometimes smaller) companies
Sep 28 06:44:09 <nbd> but not for working on your own
Sep 28 06:46:29 <nbd> the main thing that allowed me to work the way that i do is that i made my stuff open source
Sep 28 06:46:48 <nbd> and i wrote enough code that it became very visible
Sep 28 06:47:05 <nbd> that way i never had to go around looking for contracts or companies to work with
Sep 28 06:48:22 <Devastator> exactly
Sep 28 06:48:25 <eigma> do you find the city you're in matters much? for meeting clients for example?
Sep 28 06:48:58 <nbd> i've never worked for companies in the city that i live in
Sep 28 06:49:11 <Devastator> I wish I was younger, today 12 year old can code in 20 languages
Sep 28 06:49:39 <nbd> how old are you?
Sep 28 06:49:44 <Devastator> 29
Sep 28 06:49:49 <nbd> that's young enough
Sep 28 06:49:54 <nbd> younger than me actually
Sep 28 06:50:07 <Devastator> you must have 35 tops
Sep 28 06:50:12 <nbd> 31
Sep 28 06:50:38 <nbd> at that age, learning is still a very easy thing to do
Sep 28 06:50:42 <Devastator> yep, and you have way more patience than me :)
Sep 28 06:51:22 <Devastator> I plan to learn C, but the experience is what counts.. and that will take awhile
Sep 28 06:52:11 <eigma> best thing in my opinion is to force yourself to use it
Sep 28 06:52:35 <eigma> the next small script you will write, do it in C instead of whatever you're comfortable with
Sep 28 06:52:49 <nbd> not sure i'd agree with that
Sep 28 06:52:58 <Devastator> yes, I'm formatting all my computers to linux, some dual boot
Sep 28 06:53:02 <nbd> i like to always use the right tool for the task
Sep 28 06:53:14 <nbd> but i like to pick tasks where the right tool is something i haven't worked with yet ;)
Sep 28 06:53:22 <eigma> :)
Sep 28 06:53:38 <Devastator> there languages I don't know but I have empathy, like Python
Sep 28 06:53:45 <eigma> I guess I find myself writing little scripts pretty often, so that's why I chose that example
Sep 28 06:53:54 <Devastator> I find Python so powerful
Sep 28 06:54:05 <eigma> it was easy to learn Python that way, and indeed it's more suited for scripting than C
Sep 28 06:54:15 <eigma> I think it would be hard to find day to day things that are best written in C
Sep 28 06:55:02 <Devastator> my current plan is C, Java (or probably Scala), Python, HTML/CSS
Sep 28 06:55:50 <Devastator> I need some OO and HTML to make front-ends
Sep 28 06:57:41 <eigma> nbd, you wrote the original AR8216 driver?
Sep 28 06:58:07 <nbd> yes
Sep 28 06:58:17 <eigma> with docs from Atheros?
Sep 28 06:58:22 <nbd> yes
Sep 28 06:59:44 <Devastator> nbd are you having fun in #openwrt?
Sep 28 07:00:35 <nbd> yep
Sep 28 07:00:52 <Devastator> you must be
Sep 28 07:02:45 <builder> build #338 of ixp4xx is complete: Success [build successful]  Build details are at http://buildbot.openwrt.org:8010/builders/ixp4xx/builds/338
Sep 28 07:04:07 <eigma> heh
Sep 28 07:04:25 <eigma> "too many people out there are full of crap and write random stuff" :)
Sep 28 07:05:32 <Devastator> oh well, trying to find a way to study at Goethe Institute.. thousands of Euro
Sep 28 07:05:57 <Devastator> let's see if I still have Merkel's number..
Sep 28 07:09:04 <eigma> do you ever use kgdb?
Sep 28 07:09:44 <nbd> no
Sep 28 07:09:58 <nbd> never tried it
Sep 28 07:10:18 <nbd> if i do jtag debugging, i use normal gdb to debug the kernel
Sep 28 07:10:50 <nbd> i have a jtag device that speaks jtag on one side and gdb over ethernet (+ telnet) on the other
Sep 28 07:11:13 <nbd> but i only need it in rare cases
Sep 28 07:11:37 <Devastator> which jtag interface do you have? unbuffered one? have you seen diy universal jtag from Tornado (dd-wrt contributor)?
Sep 28 07:12:04 <eigma> openocd?
Sep 28 07:12:18 <nbd> abatron bdi3000
Sep 28 07:12:23 <nbd> openocd does similar stuff though
Sep 28 07:12:50 <nbd> Devastator: that stuff is only usable for flashing
Sep 28 07:12:56 <nbd> i use jtag for debugging
Sep 28 07:13:00 <eigma> jtag over ethernet?
Sep 28 07:13:06 <eigma> that's pretty neat :>
Sep 28 07:13:11 <nbd> it's a standalone box
Sep 28 07:13:17 <nbd> speaks gdb over ip on an ethernet port
Sep 28 07:13:21 <nbd> i mean the native gdb protocol
Sep 28 07:13:38 <eigma> hah
Sep 28 07:13:41 <eigma> that's excellent
Sep 28 07:14:15 <eigma> do you have the jtag pinout for buffalo wzr-600dhp? :)
Sep 28 07:14:27 <nbd> it's the normal mips ejtag layout
Sep 28 07:15:11 <eigma> compatible with BDI3000 I guess?
Sep 28 07:15:21 <nbd> right
Sep 28 07:15:26 <nbd> should work with any mips capable jtag tool
Sep 28 07:15:39 <nbd> not sure how well openocd does mips these days
Sep 28 07:15:43 <nbd> there's some support
Sep 28 07:15:45 <eigma> heh, BDI3000 is $2.3k :)
Sep 28 07:15:49 <nbd> but i never tested it
Sep 28 07:16:02 <Devastator> let's see that stuff :)
Sep 28 07:16:13 <nbd> eigma: naturally i didn't pay for it myself ;)
Sep 28 07:16:40 <eigma> hahaha
Sep 28 07:16:43 <eigma> lucky you :P
Sep 28 07:17:35 <eigma> maybe I'll stick to my improvised serial link for now
Sep 28 07:18:55 * [mbm] remembers building a crappy jtag out of a parallel port and a few diodes
Sep 28 07:19:29 <eigma> I have one, actually I have a USB Blaster clone, but it hinges on openocd support like nbd said
Sep 28 07:20:30 <Devastator> [mbm] I still have one of these :)
Sep 28 07:20:50 <eigma> and it's pretty slow.. I forget whether openocd uses the fast USB Blaster mode yet.. I remember hacking on that driver but couldn't get it working quite right
Sep 28 07:22:01 * russell-- has one of these: https://www.olimex.com/Products/ARM/JTAG/ARM-USB-OCD/ ... hasn't been plugged in for several years
Sep 28 07:23:09 <Devastator> I need to build a buffered one, it's way faster
Sep 28 07:23:18 <russell--> but i did managed to dump flash off a peplink winti board with it
Sep 28 07:23:52 <eigma> what is that?
Sep 28 07:24:16 <russell--> what is what?
Sep 28 07:24:22 <eigma> peplink winti
Sep 28 07:25:08 <russell--> i got them out of the inside of a SkyPilot SkyExtenderDualBand
Sep 28 07:25:25 <russell--> it's just an arm-based single board computer with a mini-pci slot
Sep 28 07:25:48 <russell--> we have a bunch, so i'm motivated to make them work ... eventually
Sep 28 07:26:40 <russell--> http://skypilot.trilliantinc.com/
Sep 28 07:27:16 <russell--> http://skypilot.trilliantinc.com/products/skypilot_extender.php
Sep 28 07:29:42 <Devastator> well, bed time for me..
Sep 28 07:30:19 <Devastator> tomorrow I will try to work out why sysupgrade image for router that uses seama doesn't build with proper header
Sep 28 07:30:58 <Devastator> not header, magic :P
Sep 28 07:31:17 <Devastator> or is it the same thing? I'm guessing not..
Sep 28 07:31:39 <russell--> if i'm lucky, i'll decided to give up instead.  actually hoping to sucker a college student into porting u-boot for me.
Sep 28 07:32:16 <builder> build #286 of gemini is complete: Success [build successful]  Build details are at http://buildbot.openwrt.org:8010/builders/gemini/builds/286
Sep 28 07:33:10 <eigma> bed time for me too.. good night/good morning as the case may be
Sep 28 07:36:04 <Devastator> yep :)
Sep 28 08:02:11 * russell-- also has a couple epi jeeni jtag probes in a box, never fired up
Sep 28 09:12:56 <tripolar> nbd: hi, will the group ownership of the ubus socket be implemented?
Sep 28 09:32:44 <builder> build #343 of xburst is complete: Failure [failed compile_9]  Build details are at http://buildbot.openwrt.org:8010/builders/xburst/builds/343
Sep 28 10:43:42 <nbd> Hauke: btw. wouldn't it make sense to move bgmac patches to generic?
Sep 28 10:43:52 <Hauke> yes
Sep 28 12:14:40 <mazilo> nbd: Toolchain now compiles OK. But, then the compilation crashes on package gmp as shown here (http://pastebin.com/F1wTKFTM). The reason is the extra white space `str r1,[ r0 ]'. I also included the patch in the link and now package gmp compiles OK. I hope you can include that patch to the package gmp.
Sep 28 12:55:22 <nbd> mazilo: feel free to submit a patch for that
Sep 28 13:13:49 <OpenWrt-Commits> jow r38248 trunk/package/system/ubox/Makefile
Sep 28 13:13:49 <OpenWrt-Commits> ubox: fix kmod loading for modules with varying dashes & underscores in names (#14182, #14189)
Sep 28 13:27:50 <blogic> jow_laptop: thx!
Sep 28 13:35:53 <zajec> Hauke: hey
Sep 28 13:36:01 <zajec> Hauke: have you ever tried enabling 5GHz in b43?
Sep 28 13:36:10 <zajec> Hauke: just register 5GHz channels in mac80211?
Sep 28 13:36:13 <Hauke> zajec: hi
Sep 28 13:36:22 <Hauke> no I haven't tried 5 GHz on b43
Sep 28 13:36:56 <zajec> i wonder if it requires much work
Sep 28 13:37:02 <zajec> maybe just registering channels ;)
Sep 28 13:37:07 <Hauke> does something work?
Sep 28 13:37:23 <zajec> i'll try later
Sep 28 13:37:27 <zajec> didn't start yet
Sep 28 13:37:33 <Hauke> I had some problems with beaconing in brcmsmac on 5GHz
Sep 28 13:38:01 <Hauke> the problem is still there ;-)
Sep 28 13:40:04 <KanjiMonster> Hauke: could it be data rate related? IIRC 11b/g defines some rates that aren't present in 11a, so it might cause issues if you try to send beacons in 5 GHz with a 2.4 GHz legacy rate
Sep 28 13:40:32 <Hauke> KanjiMonster: yes I assume something like that
Sep 28 14:17:33 <mazilo> nbd: Done. Ticket #14231
Sep 28 14:22:38 <nbd> btw. patches should usually go to the mailing list
Sep 28 14:22:44 <nbd> see https://dev.openwrt.org/wiki/SubmittingPatches
Sep 28 14:23:02 <mazilo> nbd: OK.
Sep 28 15:26:58 <mazilo> nbd: on ticket #14111, how do I change the status to 'close'?
Sep 28 15:27:47 <nbd> are you logged in?
Sep 28 15:28:11 <mazilo> nbd: Yes. And on the page, I only have "leave as new" option on modify ticket.
Sep 28 15:28:41 <nbd> odd
Sep 28 15:28:53 <nbd> you should ask mirko to check your permissions
Sep 28 15:28:59 <mazilo> nbd: OK.
Sep 28 15:42:01 <Devastator> good morning :)
Sep 28 15:42:13 <Devastator> almost night, but ok
