**** BEGIN LOGGING AT Thu Nov 22 02:59:59 2012
Nov 22 07:40:14 <dholbach> good morning
Nov 22 08:00:26 <fmoreau> hi all. I'm trying to use the kernel shipped by the ubuntu-n7-installer but with my own chroot (debian based). So far I've got a login prompt but the wifi connection failed. I can see from NM's log "unable to read permanent MAC address..." which seems suspicious. Could anybody give me an hint to make the wifi work ?
Nov 22 08:15:44 <lilstevie> fmoreau, you need the wifi firmware
Nov 22 08:17:19 <fmoreau> lilstevie: well I already took from ubuntu rootfs the /lib/firmware directory
Nov 22 08:17:30 <lilstevie> and the modules?
Nov 22 08:17:33 <fmoreau> sure
Nov 22 08:17:52 <fmoreau> the driver seems to load fine but it fails to read the permanent MAC address
Nov 22 08:25:02 <fmoreau> lilstevie: do you know where I can find the kernel source code ?
Nov 22 08:27:42 <lilstevie> google
Nov 22 08:38:55 <infinity> fmoreau: The linux-nexus7 source package or, as lilstevie says, Google.
Nov 22 09:26:36 <ogra_> fmoreau, you need /etc/nvram.txt too
Nov 22 09:26:59 <infinity> Which is the most awfully generic name ever.
Nov 22 09:27:05 <ogra_> or /lib/firmware/nvram.txt, not sure where it lives atm
Nov 22 09:27:06 <infinity> Why is that named that? :P
Nov 22 09:27:13 <ogra_> ask broadcom
Nov 22 09:27:31 <infinity> ogra_: Is there a hardcoded reference to that in the binary blobs? :/
Nov 22 09:27:51 <ogra_> not sure, might be that you can just change it in the module code
Nov 22 09:28:00 <infinity> If so, that might be pleasant.
Nov 22 09:28:07 <ogra_> i nerver really bothered beyond getting the wlan to work :)
Nov 22 09:28:32 <fmoreau> ogra_: thanks a lot for your usefull suggestion, we'll try it in a couple of minutes.
Nov 22 09:28:40 <fmoreau> s/we/I
Nov 22 09:29:10 <infinity> ogra_: Say, if you have any dev boards to sacrifice, can you break one in half and do a dance around it for me?
Nov 22 09:29:26 <ogra_> heh
Nov 22 09:29:40 <ogra_> what did you do that deserves this ?
Nov 22 09:29:44 <infinity> ogra_: Or some sort of voodoo to promise eglibc will build on the second try, cause I'm not doing another upload just to disable one intermittently-sad testcase. >:(
Nov 22 09:29:47 <infinity> Stupid Pandas.
Nov 22 09:30:06 <ogra_> oh man
Nov 22 09:30:57 <infinity> The test passed on the previous 4 uploads, and passed here, so I can only hope it passes on give-back of the current upload.
Nov 22 09:31:10 <infinity> Cause there's no reason it should be regressing other than "a Panda was having a bad day".
Nov 22 09:31:19 <ogra_> as usual
Nov 22 09:31:26 <ogra_> its really time they get replaced
Nov 22 09:31:47 <hrw> andale board?
Nov 22 09:31:51 <infinity> Though, I guess I shouldn't be too surprised that a test called "tst-cpuclock2" occasionally fails on an SoC that does aggressive frequency scaling to avoid exploding.
Nov 22 09:31:57 <ogra_> where do we stand wrt highbank buildds ?
Nov 22 09:32:05 <infinity> ogra_: Supply issues.
Nov 22 09:32:09 <ogra_> any changes?
Nov 22 09:32:12 <ogra_> ah
Nov 22 09:32:22 <infinity> hrw: We really don't want to replace dev boards with dev boards, we're trying to get real server kit that's actually manageable.
Nov 22 09:33:02 <infinity> hrw: Besides, replacing dev boards we actively support with ones we don't isn't clever either.  That essentially jacks up the cost of the endeavor by the salary of half a kernel engineer for a year or two.
Nov 22 09:33:03 <hrw> infinity: sure, but when those will be finally somewhere else then in news articles...
Nov 22 09:34:03 <infinity> Also, this particular issue wouldn't be better on andale, or any other dev board.
Nov 22 09:34:05 <ogra_> we should just go with arm64 in qemu :P
Nov 22 09:34:17 <infinity> All ARM SoCs aggressively frequency scale to avoid overheating.
Nov 22 09:34:24 <infinity> The solution is to glue heatsinks to them. :P
Nov 22 09:34:33 <infinity> ogra_: qemu can't do arm64.
Nov 22 09:34:44 <ogra_> it will at some point :)
Nov 22 09:34:48 <hrw> I heard rumours that panda5 will come with DIY heatsink set
Nov 22 09:34:55 <ogra_> lol
Nov 22 09:35:03 <suihkulokki> infinity: not all, just the fast ones :P
Nov 22 09:35:16 <infinity> suihkulokki: Okay, fair.  All the ones I'd use as buildds. :)
Nov 22 09:35:30 <hrw> and info: "if you run TI kernel, it will work. if mainline then put heatsink until we merge whole PM stuff"
Nov 22 09:35:50 <infinity> hrw: Yeah, the 4460 has similar caveats (but didn't come with a heatsink)
Nov 22 09:36:18 <infinity> hrw: Still, people using these boards at 100% load (like buildds) should put heatsinks on, or you're not actually getting full clock all the time.
Nov 22 09:36:26 <hrw> after playing with Archos tablet (with 4430 and 512MB ram) I prefer to avoid omap4 line
Nov 22 09:36:30 <infinity> Maybe I should mail a bag of heatsinks to London and have someone glue one on each Panda.
Nov 22 09:37:04 <ogra_> you think they dont have heatsinks in the UK ?
Nov 22 09:37:20 <ogra_> or are canadian ones just colder ?
Nov 22 09:37:48 <infinity> ogra_: I think we don't have a datacenter engineer to go shopping and faff about, so the more work I do in advance, the easier it is to convince a sysadmin to wander down and stick them on. :P
Nov 22 09:38:07 <ogra_> heh, k
Nov 22 09:38:59 <infinity> (Plus, for just about anything except teabags, shopping in North America and shipping it to the UK is always cheaper than shopping in the UK)
Nov 22 09:39:24 <hrw> not always
Nov 22 09:39:32 <infinity> Well, no.  Not always.  But very often.
Nov 22 09:39:59 <infinity> Probably not for 5$ crap heatsinks.
Nov 22 09:40:20 <infinity> Unless one shipped by boat.
Nov 22 09:40:31 <infinity> Or heatsink mule.
Nov 22 09:40:44 <infinity> "Why are those heatsinks in a condom?"
Nov 22 09:41:01 <ogra_> uuuh
Nov 22 09:41:54 <suihkulokki> I really didn't want to imagine that
Nov 22 09:42:20 <suihkulokki> :P
Nov 22 09:42:31 <infinity> ogra_: Drug mules?  Condoms full of heroin in various body cavities?  Nevermind. :P
Nov 22 09:45:08 * ogra_ shudders ... now i regret that i just uploaded the microSD content of my mx6 for you :P
Nov 22 09:45:54 <infinity> ogra_: Are you imagining jagged heatsinks in uncomfy places?
Nov 22 09:45:58 <ogra_> hmm, well, "am still uploading" .... i shoudl upgrade to more than 2Mbit
Nov 22 09:46:09 <ogra_> i'm trying not to
Nov 22 09:46:12 <ogra_> lalalala
Nov 22 09:47:22 <suihkulokki> and yes, pandas fit a heatsink fine: https://plus.google.com/101339419642360856354/posts/FUzUk5U4kJe
Nov 22 09:51:31 <ogra_> infinity, http://people.canonical.com/~ogra/mx6/mmcblk0p1.img needs to be dd'ed to the start of the micro SD, http://people.canonical.com/~ogra/mx6/mmcblk0p2.tgz needs to go onto a vfat partition in the card, http://people.canonical.com/~ogra/mx6/ubuntu-precise-imx6-sabre-77f462e.tar.gz is a snapshot of the source tree from kernel.ubuntu.com
Nov 22 09:56:35 <infinity> ogra_: Cool.  And it boots from the micro or the big slot?
Nov 22 09:58:44 <victorp> ogra_ ping
Nov 22 09:59:09 <victorp> I am trying to assign https://bugs.launchpad.net/ubuntu-nexus7/+bug/1065644 to someone relevant, is this something foundations should be looking at?
Nov 22 09:59:09 <ubot2> Launchpad bug 1065644 in ubuntu-nexus7 "plymouth causes a hard reset of the nexus" [Critical,Confirmed]
Nov 22 09:59:16 <lilstevie> infinity, that is a horrible mental picture
Nov 22 09:59:18 <lilstevie> :/
Nov 22 09:59:25 <infinity> lilstevie: You're welcome.
Nov 22 10:00:01 <lilstevie> I think I am going to go afk for a little bit
Nov 22 10:00:30 <lilstevie> to vomit
Nov 22 10:00:31 <lilstevie> :p
Nov 22 10:02:28 <ogra-cb__> victorp, take me
Nov 22 10:02:42 <victorp> ogra-cb__, ? do you mean pick me?
Nov 22 10:02:44 <ogra-cb__> infinity, micro
Nov 22 10:02:50 <infinity> I think I may join lilstevie...
Nov 22 10:02:53 <ogra-cb__> victorp, err, yes
Nov 22 10:02:57 <victorp> lol
Nov 22 10:03:04 <lilstevie> that is a scary though
Nov 22 10:03:05 <lilstevie> t
Nov 22 10:05:43 <victorp> ogra-cb__, do you get this bug in your system at all? I dont
Nov 22 10:05:43 <victorp> https://bugs.launchpad.net/ubuntu-nexus7/+bug/884041
Nov 22 10:05:44 <ubot2> Launchpad bug 884041 in ubuntu-nexus7 "Screen brightness not adjusted when switching from AC to battery" [High,Confirmed]
Nov 22 10:05:57 <victorp> as in, it does dim
Nov 22 10:06:28 <ogra-cb__> it didnt dim for me i think
Nov 22 10:06:38 <fmoreau> ogra_: unfortunatly I already have nvram.txt because its located in /lib/firmware which I have copied earlier ..
Nov 22 10:06:47 <ogra-cb__> my device is currently slightly borked due to running raring
Nov 22 10:07:07 <ogra-cb__> so its hard to compare
Nov 22 10:10:03 <ogra-cb__> fmoreau, well, i would actually rather blame userspace anyway, what are you using to manage the device ?
Nov 22 10:12:46 <fmoreau> ogra-cb__: network-manager. The thing is that the error seems to be related to the driver which can't read the MAC address (that's what suggest the error from the kernel logs)
Nov 22 10:14:09 <ogra-cb__> that message is normal i think
Nov 22 10:14:44 <ogra-cb__> infinity, http://paste.ubuntu.com/1376788/ does that look sane (i know i'll mess it up again so please look twice :) )
Nov 22 10:16:37 <fmoreau> ogra-cb__: I can read this for example : dhd_preinit_ioctls: can't get MAC address, error=-5
Nov 22 10:24:57 <infinity> ogra-cb__: Should do, but please group it with the other ubuntu-preinstalled instead of hiding lubuntu in the middle. :P
Nov 22 10:26:04 <ogra-cb__> k, i'll move it one up
Nov 22 10:32:39 <fmoreau> ogra-cb__: do you think it could be related to wpasupplicant which is version 0.7.3 in my rootfs wherease version 1.0 on ubuntu one ?
Nov 22 10:33:28 <ogra-cb__> yeah, something liek that
Nov 22 10:33:34 <fmoreau> ok
Nov 22 10:33:40 <fmoreau> will try to update that package
Nov 22 10:33:50 <ogra-cb__> if you copied kernel, modules and firmware, there shouldnt be any reason that the kernel side doesnt work
Nov 22 10:34:01 <fmoreau> ogra-cb__: that's what I'm thinking to
Nov 22 10:34:04 <fmoreau> +o
Nov 22 10:34:25 <fmoreau> but since the driver showed some errors... I was tempted to think that the driver was the culprit
Nov 22 10:34:48 <ogra-cb__> well, i remember seeing some MAC related warnings
Nov 22 10:35:05 <ogra-cb__> my device is currently unbootable and i'm waiting for a nnew image
Nov 22 10:35:19 <ogra-cb__> once i booted that i'll check dmesg
Nov 22 10:35:51 <fmoreau> thanks :)
Nov 22 10:36:09 <fmoreau> but actually I dumped the dmesg after booting the ubuntu image
Nov 22 10:36:20 <fmoreau> and there're much less errors than what I'm getting
Nov 22 10:36:26 <ogra-cb__> hmm, k
Nov 22 10:36:45 <fmoreau> this one is an example: dhd_preinit_ioctls: can't get MAC address, error=-5
Nov 22 10:44:21 <fmoreau> ogra-cb__: BTW can the userspace be in armv7l whereas the kernel is build in armv7hl ?
Nov 22 10:44:49 <xranby> fmoreau: yes,    because there is no "armhf" kernel   the kernel is the same for amrel and armhf
Nov 22 10:45:41 <ogra-cb__> should theoretically work
Nov 22 10:46:05 <fmoreau> ok thanks both
Nov 22 11:10:01 <fmoreau> ogra-cb: same after updating wpasupplicant :(
Nov 22 11:11:37 <fmoreau> ogra-cb: do you think that could be related to initrd ? I actually don't use it.
Nov 22 11:12:05 <ogra-cb> not really
Nov 22 11:12:31 <ogra-cb> the wlan driver is builtin iirc
Nov 22 11:12:48 <ogra-cb> so onlz having the firmware in the right place counts
Nov 22 12:45:40 <fmoreau> can't flashboot dump the 'userdata' partition so I can retrieve some dumped files on my host ?
Nov 22 12:47:33 <ogra-cb> sadly it only works in one direction
Nov 22 12:47:43 <ogra-cb> there aare the nandroid backup tools
Nov 22 12:48:24 <ogra-cb> ogra@nexus7:~$ cat /var/log/installer/media-info
Nov 22 12:48:24 <ogra-cb> Ubuntu Raring Ringtail (development branch) - armhf (20121122-11:16)
Nov 22 12:48:25 <ogra-cb> ogra@nexus7:~$
Nov 22 12:48:27 <ogra-cb> yay
Nov 22 12:48:53 * ogra-cb makes a checkmark on bug 1080747
Nov 22 12:48:54 <ubot2> Launchpad bug 1080747 in livecd-rootfs (Ubuntu Raring) "Set a build stamp for pre-installed images" [Medium,Fix released] https://launchpad.net/bugs/1080747
Nov 22 12:50:12 <fmoreau> ogra-cb: sad that could be really usefull sometimes
Nov 22 12:56:24 <ogra-cb> yes, i would love to eb abe to create a backup during installlation that you can play back to the device
Nov 22 13:02:33 <fmoreau> ogra-cb: do you know which wpa_supplicant's driver should I use ?
Nov 22 13:08:21 <fmoreau> wext I guess
Nov 22 13:13:50 <lilstevie> ogra-cb, are the drivers in the nvidia-tegra3 package the original r16 ones, or the r16.2 ones?
Nov 22 13:17:35 <fmoreau> ogra-cb: where can I find the source package of wpa_supplicant used on the ubuntu image ?
Nov 22 13:23:55 <janimo> ogra-cb, are the raring images installable and usable? I just saw they are on cdimage :)
Nov 22 13:24:42 <janimo> fmoreau, apt-get source wpasupplicant or do you want something else?
Nov 22 13:25:18 <fmoreau> I'd like to retrieve it from the web instead.
Nov 22 13:25:59 <fmoreau> http://packages.ubuntu.com/fr/raring/wpasupplicant
Nov 22 13:32:15 <janimo> fmoreau,  I usually look at LP for that for example https://launchpad.net/ubuntu/+source/wpasupplicant
Nov 22 13:32:29 <janimo> there you have links to all versions
Nov 22 13:32:39 <ogra-cb> lilstevie, something inbetween, i got them as pre-release weeks before they showed up on developer.nvidia.com
Nov 22 13:33:05 <lilstevie> ogra-cb, ah ok
Nov 22 13:33:27 <ogra-cb> janimo, kind of ... still weeding out some bugs with the traball installer and the default settings are still missing (you need a kbd/mouse atm)
Nov 22 13:33:54 <ogra-cb> janimo, and it only works for people that can use -S with fastboot
Nov 22 13:34:08 <ogra-cb> (doesnt work on all devices)
Nov 22 13:34:31 <ogra-cb> janimo, beyond that yes, i just did an install
Nov 22 13:35:13 <ogra-cb> (using http://cdimage.ubuntu.com/daily-preinstalled/current/)
Nov 22 13:36:36 <ogra-cb> janimo, daily builds are running at 13:32 UTC every day now ... next image should show up at 15:30 UTC or so
Nov 22 13:36:49 <ogra-cb> (if i didnt mess it up at least)
Nov 22 13:45:43 <ogra-cb> sigh, so using resize2fs on the nexus rootfs makes the sys tem go into a reboot loop
Nov 22 13:46:10 <ogra-cb> even when i onlz resize my slightly to small 6G rootfs
Nov 22 13:46:19 <ogra-cb> (adding a few MB)
Nov 22 13:46:55 <ogra-cb> sad
Nov 22 13:59:40 <fmoreau> ogra-cb: the cmdline in boot.img is "root=/dev/mmcblk0p9 ro console=tty1 fbcon=rotate:1 quiet" but I don't think it's the one which is passed during normal boot (once the installation is finished, is it ?
Nov 22 14:00:55 <ogra-cb> fmoreau, it is, but the bootloader prefixes it with some hardcoded stuff
Nov 22 14:01:22 <fmoreau> oh I see
Nov 22 14:06:08 <marvin24_> janimo, ogra-cb: any chance to build an ac100 kernel?
Nov 22 14:06:32 <janimo> marvin24_, I can't today
Nov 22 14:06:46 <janimo> marvin24_, new code in the branch?
Nov 22 14:06:46 <marvin24_> janimo: not today ...
Nov 22 14:06:55 <marvin24_> I updated to 16r2
Nov 22 14:07:04 <marvin24_> which fixed the console problem
Nov 22 14:07:24 <janimo> marvin24_, well not today but sometimes soon I guess :)
Nov 22 14:07:24 <marvin24_> but introduced a different one ;-)
Nov 22 14:07:39 <marvin24_> janimo: many thanks!
Nov 22 14:07:48 <janimo> I wish someone else maintained that kernel in ubuntu I have not been using that device for a long time
Nov 22 14:08:12 <marvin24_> janimo: I would if I had more time
Nov 22 14:08:20 <marvin24_> compiling a kernel isn't the problem
Nov 22 14:08:22 <janimo> marvin24_, I understand :)
Nov 22 14:08:27 <marvin24_> uploading is a mess
Nov 22 14:08:40 <marvin24_> or building a package out of it
Nov 22 14:08:42 <marvin24_> grrr
Nov 22 14:08:43 <janimo> marvin24_, uploading when it comes to getting upload access?
Nov 22 14:08:52 <marvin24_> no, I mean packaging
Nov 22 14:08:55 <janimo> marvin24_, well it is a mess I agree
Nov 22 14:09:05 <marvin24_> I surely could upload it to the project page
Nov 22 14:09:30 <marvin24_> maybe I can setup some scripts to make it easier locally
Nov 22 14:09:30 <janimo> marvin24_, at least for getting testers that too would be great
Nov 22 14:09:42 <janimo> I keep planning on making an autobuilder of debs for ac100
Nov 22 14:09:46 <marvin24_> yeah, weekend isn't far away anymore
Nov 22 14:09:47 <janimo> but not quite making it :(
Nov 22 14:10:44 <janimo> marvin24_, I documented the steps used for the nexus7 kernel which I based on the ac100 one here:
Nov 22 14:10:46 <janimo> https://wiki.ubuntu.com/Nexus7/Kernel?action=show&redirect=Nexus7%2FKernelBuild#Building_the_kernel
Nov 22 14:10:59 <janimo> it is at least some start, and exactly what I use
Nov 22 14:11:12 <janimo> more or less the same as you'd find on the ubuntu or linaro wiki pages
Nov 22 14:11:16 <janimo> which it is inspired from
Nov 22 14:11:39 <janimo> but it is only for tinkering to make a local deb not the full packaging ritual for ubuntu
Nov 22 14:11:56 <janimo> so it is something you probably already know and do anyway
Nov 22 14:12:40 <marvin24_> a different solution would be to add support for both machines in the same kernel
Nov 22 14:12:56 <marvin24_> but I need to check if this would work
Nov 22 14:12:59 <janimo> both tegra2 and tegra3 is not really doable in 3.1 eight?
Nov 22 14:13:02 <janimo> right
Nov 22 14:13:10 <marvin24_> it's possible in mainline kernel
Nov 22 14:13:20 <marvin24_> but you may be right on 3.1
Nov 22 14:13:30 <marvin24_> too many IS_TEGRA2x_SOC defines
Nov 22 14:13:33 <janimo> I know, that is why I keep hoping we get 3.8 for ac100 in 13.04 :)
Nov 22 14:13:47 <marvin24_> just clone my branch ;-)
Nov 22 14:14:00 <marvin24_> I can also setup some patches against 3.8
Nov 22 14:14:02 <janimo> marvin24_, how close are we to have it working?
Nov 22 14:14:06 <marvin24_> to make display light up
Nov 22 14:14:14 <tassadar_> janimo: we managed to get kexec working on nexus7 last night, is there a chance to add hardboot patches to ubuntu's kernel?
Nov 22 14:14:21 <janimo> marvin24_, if you can make ac100 work on 3.8 we get maintenance almost for free
Nov 22 14:14:25 <marvin24_> janimo: only display (backlight and tegra drm)
Nov 22 14:14:29 <janimo> and not have to carry a diverging package
Nov 22 14:14:34 <marvin24_> eh, wrong, tegra-drm was merged to 3.8
Nov 22 14:14:44 <marvin24_> so only backlight left
Nov 22 14:15:02 <ogra-cb> well, does it work with the binary drivers is the question
Nov 22 14:15:06 <janimo> tassadar_, I am not familiar with what hardboot is? If you get a set of patches it will definitely be at least looked at and considered :)
Nov 22 14:15:09 <marvin24_> janimo: it may not be until 3.9 or 3.10 before this will have a change to get merged
Nov 22 14:15:42 <marvin24_> any none else notices that vger.kernel.org stopped to deliver mails?
Nov 22 14:15:44 <janimo> marvin24_, if it works it does not need to be mainlined, we could carry it in ubuntu. But at least have a kernel based on 3.8 as the rest of Ubuntu will
Nov 22 14:16:03 <marvin24_> ok, will try to create a patchset
Nov 22 14:16:13 <janimo> marvin24_, that would be awesome
Nov 22 14:16:34 <janimo> as long as it supports what 3.1 does I see no reason not to move to 3.8 as well
Nov 22 14:16:55 <xnox> ogra-cb: whatever you are seeing on arm (desktop background/ubiquity not appearing for ages) I see in the VM as well.
Nov 22 14:17:06 <janimo> same for nexus7 btw but noone has yet looked at porting those changes forward
Nov 22 14:17:10 <ogra-cb> xnox, there was aa bug i saw passing by
Nov 22 14:17:19 <tassadar_> kexec-hardboot - normal kexec does not work on some (most?) android devices because of the drivers, so this patch does the same thing as kexec, but with full device reboot
Nov 22 14:17:21 <marvin24_> janimo: well, given that 3.1 broke suspend, we'll be at the same feature level ;)
Nov 22 14:17:23 <janimo> not a prio in the current setup, where we just wanted a working device
Nov 22 14:17:29 <janimo> marvin24_, ;)
Nov 22 14:17:56 <ogra-cb> marvin24_, well, there are no issues on the nexus with suspend atm
Nov 22 14:18:15 <janimo> tassadar_, as I said I am not familiar with kexec at all. The ubuntu-kernel team and its mailing list would be a much better place to bring this up
Nov 22 14:18:22 <marvin24_> ogra-cb: yeah, it must be related to nvec code then
Nov 22 14:18:39 <marvin24_> I don't know how nexus7 suspends though
Nov 22 14:18:45 <janimo> or at least as a bug with optional patches filed against  the linux-nexus7 package
Nov 22 14:25:19 <ogra-cb> libO and TB dropped from all armhf images for now
Nov 22 14:25:29 <ogra-cb> that shoudll give us a properly sized image
Nov 22 14:44:41 <brendand> ogra-cb, can the daily images for the nexus7 be used?
Nov 22 14:48:11 <ogra-cb> brendand, only manually atm only on devices that can handle oversized images (fastboot -S) and you need a kbd and mouse atm
Nov 22 14:48:22 <ogra-cb> (most of that should be fixed on monday)
Nov 22 14:48:45 <brendand> ogra-cb, do i have one that can handle oversized images?
Nov 22 14:48:58 <brendand> ogra-cb, keyboard - check, mouse - check
Nov 22 14:49:03 <ogra-cb> no idea, we're not sure which ones can and which cant
Nov 22 14:49:15 <ogra-cb> i haven an 8G one that definitely can
Nov 22 14:49:22 <ogra-cb> *have
Nov 22 14:49:46 <ogra-cb> waht model do you have ?
Nov 22 14:49:58 <ogra-cb> i think the *g ones didnt have issues with it
Nov 22 14:50:04 <ogra-cb> 8G
Nov 22 14:50:51 <ogra-cb> Bug 1079729 has a manual step by step guide
Nov 22 14:50:51 <ubot2> Launchpad bug 1079729 in ubuntu-nexus7 "Ubuntu uninstallable on 32GB 3G Nexus 7" [High,Confirmed] https://launchpad.net/bugs/1079729
Nov 22 14:51:14 <ogra-cb> (you need -S 630M for the flash userdata call)
Nov 22 14:52:46 <brendand> ogra-cb, i got mine at UDS
Nov 22 14:53:09 <brendand> ogra-cb, if i try, what's the worst that can happen?
Nov 22 14:54:58 <brendand> ogra-cb, mine is 16GB
Nov 22 14:55:52 <ndec_> ogra-cb: hi! what kernel will you be using for 13.04 for omap? are you still planning to have a ti-omap4 branch?
Nov 22 14:56:52 <ogra-cb> ndec_, that question better goes to ppisati, i know he wanted to ask robclark for feedback about necessary patches to make PVR work first
Nov 22 14:57:19 <ndec_> well for PVR only, it's very much possible to use mainline or close to it.
Nov 22 14:57:26 <ogra-cb> brendand, it wouldnt fail to find the rootfs and not boot (indeed you can always reflash)
Nov 22 14:57:38 <ndec_> problems come with h/w video decode and power management...
Nov 22 14:57:48 <ogra-cb> ah
Nov 22 14:57:59 <ogra-cb> ppisati, ^^^
Nov 22 14:58:35 <ogra-cb> ndec_, what will you stay on ? or is omap4 dead anyway ?
Nov 22 14:58:45 <ndec_> hehe
Nov 22 14:58:56 <robclark> ogra-cb, yeah, should be a matter of 3 or 4 patches to get pvr...  I have a pvr branch on my github tree which was a quick/dirty/rush rebase of pvr stuff onto one of my working branches for 3.7..
Nov 22 14:59:27 <ogra-cb> right, i'm not super concerned about video playback, but PM sounds serious
Nov 22 14:59:55 <ndec_> well.. and PM is much more unlikely to come from mainline soon.
Nov 22 14:59:58 <ogra-cb> after all its up to ppisati though
Nov 22 14:59:59 <robclark> you can always do mechanical PM  (ie. a heatsink) :-P
Nov 22 15:00:20 <ogra-cb> hard to distribute heatsinks inside images though
Nov 22 15:00:25 <ogra-cb> :)
Nov 22 15:00:28 <robclark> true
Nov 22 15:00:30 <ndec_> active power management with a fridge
Nov 22 15:00:37 <ogra-cb> heh
Nov 22 15:00:38 <robclark> heheh
Nov 22 15:22:28 <ppisati> robclark: can you point me to these pvr patches for mainline?
Nov 22 15:22:52 <ppisati> ndec_: about pm, i'll try to pick all the dvfs stuff and see how much it is
Nov 22 15:23:04 <ppisati> ndec_: besides, there;s one thing that i never understood
Nov 22 15:23:22 <ppisati> ndec_: mainline doesn't have DVFS, bu omap2plus work on omap4/panda
Nov 22 15:23:32 <ppisati> ndec_: shouldn't it melt then?
Nov 22 15:24:14 <ogra-cb> not with a heatsink :)
Nov 22 15:24:33 <robclark> ppisati, look at https://github.com/robclark/kernel-omap4/commits/pvr at the 2nd thru 5th commits
Nov 22 15:24:50 <robclark> ppisati, it probably runs but just not at highest clock speeds
Nov 22 15:25:08 <ppisati> robclark: ok, i'll do
Nov 22 15:25:18 <ppisati> and is there a dvfs branch somewhere?
Nov 22 15:26:59 <robclark> not sure about dvfs.. I guess there are various branches with different implementations over the years.. I'm not a PM expert, but I guess it somehow ties up in common clock framework and other changes happening upstream so rebasing from an old kernel version might not be so straightforward..
Nov 22 15:30:55 <ndec_> ppisati: no there is no dvfs branch that can be easily picked up.
Nov 22 15:31:23 <ndec_> and don't be confused we have cpufreq support... so you can actually change the CPU freq... but that doesn't change the 'voltage'.
Nov 22 15:31:35 <ndec_> so in effect, it's DFS, not DVFS ;-)
Nov 22 15:31:45 <ndec_> and no changing the voltate means that you don't impact the PM...
Nov 22 15:39:00 <fmoreau> is there a limit on the size of the image that fastboot can upload on the N7 ?
Nov 22 15:39:21 <fmoreau> it seems that image > 700Mo make fastboot to be stuck
Nov 22 15:41:17 <ppisati> ndec_: but correct me if i'm mistaken, when you say that the main problem with mainline is PM, you mean the lack of DVFS, right?
Nov 22 15:42:58 <ndec_> not just DVFS... thermal management, clock gating, OFF mode...
Nov 22 15:43:29 <ppisati> and do you have some topic branches for these?
Nov 22 15:43:57 <ppisati> because, we picked 3.8 for R and i need to collect all the pieces
Nov 22 15:44:20 <ppisati> even if it's not for 3.8, at least knowing what to pick is enough
Nov 22 15:44:28 <ppisati> i'll do the rest
Nov 22 16:07:37 <ogra-cb> fmoreau, yes, the limit is somewhere between 680 and 700M
Nov 22 16:08:01 <fmoreau> ogra-cb: hmm is there a workaround to upload a bigger file ?
Nov 22 16:08:24 <ogra-cb> you can use the -S option when flashing
Nov 22 16:08:30 <ogra-cb> but its not very reliable
Nov 22 16:13:47 <fmoreau> what does -S mean ? can't see a description for it in --help ...
Nov 22 16:13:59 <RaYmAn> ogra-cb: fwiw, as far as I know, the reason for the limit is that it stores it temporarily on the staging partition - so the limit is the size of that (usually roughly the same as the system partition)
Nov 22 16:14:32 <ogra-cb> ah, i always thought it uses a tmpfs
Nov 22 16:30:22 <tassadar_> hmm, should I use the kernel-team mailing list to send patch for nexus 7 kernel? I mean isn't there like arm or nexus7 mailing list?
Nov 22 16:31:36 <ogra-cb> no
Nov 22 16:32:29 <ogra-cb> nexus is just another ubuntu device, ubuntu-devel, ubuntu-desktop and the kernel list should be used
Nov 22 16:33:13 <tassadar_> okay
Nov 22 16:43:25 <brendand> ogra-cb, will fastboot hang if i can't install the raring daily?
Nov 22 16:44:00 <ogra-cb> yes
Nov 22 16:44:16 <ogra-cb> you need to use -S
Nov 22 16:44:21 <Haffe> A question. Has anyone here tried to use a usb DVB-t reciever with an arm system?
Nov 22 16:45:00 <ogra-cb> Haffe, yes, works fine, it helpos to have a proper graphics driver for your hardware though
Nov 22 16:45:28 <Haffe> I was looking into getting an ODROID-X to use as a PVR.
Nov 22 16:51:31 <brendand> ogra-cb, is it okay to ctrl+c the fastboot flash userdata command?
Nov 22 16:59:38 <ogra-cb> brendand, well, the flashing you did will be trashed indeed, but beyond that it doesnt do any harm
Nov 22 17:00:03 <brendand> ogra-cb, i need to just run the userdata flash with -S?
Nov 22 17:00:41 <ogra-cb> sudo fastboot -S 630M flash /path/to/unzipped/*.img
Nov 22 17:01:12 <ogra-cb> tomorrows image will be smaller (hopefully small enough) and should eb installable without -S
Nov 22 17:01:27 <brendand> ogra-cb, i mean, the bootimg line doesn't need it right?
Nov 22 17:01:46 <ogra-cb> right
Nov 22 17:02:02 <ogra-cb> only files that are to big need it, bootimg is only 8M
Nov 22 17:03:34 <brendand> ogra-cb, i remember now - this is the option which cuts the image up into chunks, right?
Nov 22 17:04:24 <ogra-cb> yeah
Nov 22 17:04:42 <brendand> sparse, that's it
Nov 22 17:04:49 <ogra-cb> apparently it has issues reassembling it sometimes
Nov 22 17:04:53 <ogra-cb> yeah
Nov 22 17:07:42 <brendand> ogra-cb, crap - dumped to busybox
Nov 22 17:08:23 <brendand> /dev/mmcblk0p9 cannot be mounted
Nov 22 17:08:51 <brendand> ah well, back to the quantal image
Nov 22 17:10:13 <brendand> oh noes - i can't get back to fastboot mode :/
Nov 22 17:10:43 <brendand>  phew, that was scary
Nov 22 17:15:29 <ogra-cb> yeah, its a bit hard to get to the flash mode if the device is in constant reboot mode
Nov 22 17:16:10 <ogra-cb> tomorrows image hopefully works
Nov 22 17:16:58 <ogra-cb> i was told that -S doesnt break 100% of the time, so if you try over and over you might hit a successfull flash at some point
Nov 22 18:28:31 <Tassadar> nice, successfuly kexec-hardboot-ed to ubuntu from cyanogenmod :)
Nov 22 18:47:27 <[mbm]> cool.
Nov 22 19:00:12 <VarmVaffel> I'm having some DNS trouble while connected to a pppd 3G USB-modem connection
Nov 22 19:00:23 <VarmVaffel> I can't use any URLs basicly
Nov 22 19:00:31 <VarmVaffel> but all IPs work just fine
Nov 22 19:01:14 <VarmVaffel> I've tried changing /etc/ppp/resolv.conf to use googles 8.8.8.8 for instance, but it doesn't work either
Nov 22 19:01:22 <VarmVaffel> any tips is appreciated
Nov 22 19:14:48 <VarmVaffel> ok nvm I figured it out
Nov 22 19:15:23 <VarmVaffel> the resolv.conf should be in /etc not /etc/ppp
Nov 22 20:50:28 <fmoreau> how can I see if a binary is armhl or armel ?
Nov 22 21:04:07 <infinity> fmoreau: readelf -A /path/to/binary | grep Tag_ABI_VFP_args
Nov 22 21:04:23 <infinity> fmoreau: For armhf, it'll say "Tag_ABI_VFP_args: VFP registers"
Nov 22 21:06:29 <fmoreau> infinity: readelf -A doesn't output anything here
Nov 22 21:07:06 <infinity> fmoreau: Where is "here"?
Nov 22 21:07:18 <infinity> fmoreau: It works fine on Ubuntu precise and above, at least.
Nov 22 21:08:00 <fmoreau> infinity: I just gave it a try on my host (debian)
Nov 22 21:08:18 <infinity> fmoreau: It also won't output much of anything useful for binaries without an eabi section.
Nov 22 21:08:50 <infinity> fmoreau: So, anything not ARM, or anything not actually an ELF binary.
Nov 22 21:09:56 <fmoreau> infinity: ok thanks
Nov 22 21:10:05 <infinity> It absolutely does work on Debian, though.
Nov 22 21:10:28 <infinity> So, I'm a little curious about what you were doing that didn't.
Nov 22 21:17:06 <fmoreau> infinity: for example doing "readelf -A /bin/bash" on my host doesn't show anything
Nov 22 21:17:54 <infinity> fmoreau: Yes, but what is your host?
Nov 22 21:18:01 <fmoreau> debian wheezy
Nov 22 21:18:07 <infinity> I meant what architecture. :P
Nov 22 21:18:13 <fmoreau> x86-64
Nov 22 21:18:26 <infinity> Yeah.  No extended attributes section on amd64 binaries.
Nov 22 21:18:30 <fmoreau> ah ok
Nov 22 21:18:52 <fmoreau> I was confused by "or anything not actually an ELF binary."
Nov 22 21:19:35 <infinity> fmoreau: See http://paste.ubuntu.com/1378079/
Nov 22 21:20:41 <fmoreau> I see :) thanks !
Nov 22 21:22:04 <infinity> fmoreau: http://paste.ubuntu.com/1378081/
Nov 22 21:22:22 <infinity> fmoreau: The above being a more interesting example, since on precise, armel and armhf were identical except for sf/hf being flipped.
Nov 22 21:22:35 <infinity> fmoreau: And you can see the only tag that changes is Tag_ABI_VFP_args
Nov 22 21:22:55 <fmoreau> I see, so they both are armv7
Nov 22 21:23:02 <fmoreau> but one with hfp
Nov 22 21:23:05 <infinity> Right.
Nov 22 21:23:37 <fmoreau> thanks for explaining :)
Nov 22 21:28:44 <fmoreau> infinity: any idea why the touchscreen doesn't work with my rootfs ? I started X + openbox, evtest /dev/input/event0 reports some events  but the mouse cursor doesn't move on the touchscreen.
Nov 22 21:36:11 <infinity> fmoreau: That, I have no idea about.
Nov 22 21:38:51 <fmoreau> ok
Nov 22 23:45:09 <ptl> hi
Nov 22 23:45:19 <ptl> does anyone know where I can get the source for the kernel used in the Nexus7, with all patches?
Nov 22 23:45:25 <ptl> and config
Nov 22 23:46:51 <Tassadar> https://wiki.ubuntu.com/Nexus7/Kernel
Nov 22 23:47:07 <Tassadar> or, the short form, git clone git://kernel.ubuntu.com/hwe/ubuntu-nexus7.git
Nov 22 23:47:08 <k1l> it should be in the AOSP stuff
Nov 22 23:47:24 <Tassadar> or do you mean the android kernel..?
Nov 23 01:04:24 <ptl> tassadar, I think the android kernel is the one used, isn't it?
Nov 23 01:07:52 <lilstevie> ptl, it is, but it has been modified to work with ubuntu better.
