* ogra hugs lool ... awesome, thanks !00:03
loologra: how is it going for you guys?  is the latest hardware pleasing?  :-)00:04
ograits wonderfully fast00:06
ograwe have 400MHz RAM now00:06
ograstill enough small issues with 1080p video processing and sound though00:07
ograbut release looks really good for panda, blaze and oma4 tablet :)00:07
ogra*omap400:07
sakomanrsalveti: is the ability to saveenv to sd cards something of interest (on panda and beagle xM)?00:09
sakoman(would require a raw partition to be added to the sd card)00:11
rsalvetisakoman: probably, but from the distro pov00:11
rsalveti*not00:11
ograsakoman, could it just create boot.scr right away ?00:11
sakomanogra: no, file systems in u-boot are read only00:11
ograah, sad00:12
sakomanindeed00:12
ograthat would be the most elegant solution00:12
ograread boot-scr as input and write it again on saveenv00:12
cooloneysakoman, so we modify u-boot to support this feature, heh -:)00:13
sakomanon the other hand, with a bit of work one might be abble to eliminate the FAT partition and put MLO and u-boot in the raw partition00:13
* ogra is not a big fan of raw partitions from an image creator POV00:14
sakomancooloney: I suspect that would be difficult to get upstream00:14
ograpainful to create in a sane way (you need to wrap a non data partition around it) ...00:15
sakomanogra: understood, it would require 3 carefully crafted dd commands00:16
ograand a lot of math for parted (which we use on the image builders)00:16
cooloneysakoman, it looks like no other choice to me, since we need to update boot.scr which is in SD partition.00:17
sakomanOK, just wanted to ask00:17
ogracooloney, well, we have ubootenvtools which can read/write the environment from/to NAND already00:17
cooloneyogra, or is that possible for us to store boot.scr on the board instead of SD00:17
ogra*uboot-envtools00:17
sakomanit is a technique used in phones that run from emmc00:17
cooloneyogra, cool, man00:17
cooloneyogra, that's what i wanna ask00:18
loolsakoman: One thing which I found hard the last time I looked at this kind of stuff is creating an environment from userspace00:38
loolsakoman: The current tools allow manipulating it, but not creating one from scratch00:38
sakomanlool: understood, I'll take a look at that.  may not be a big deal00:39
loolsakoman: I worked on a set of patches a while ago to transform the tools in the u-boot tree to work on files as well as MTDs, but for some reason I had an error in the checksum part of things, and never took the time to track it down00:40
loolI didn't like the result though, I had tons of ifdefs; I should have refactored the code to have backend specific read/write instead of ifdefing all the read/writes00:41
sakomanlool: want to send me the patches?00:41
loolif I manage to find them00:41
* lool scratches head00:41
looloh I actually found the perl script I had started to do it in perl instead00:42
* sakoman has been known to user perl on occasion00:44
loolsakoman: Hmm did not find it; I found files from after and before, so either it's on my previous laptop now powered off, or it was rm-rfed in a kill-this-old-stuff fury00:44
sakomanlool: no problem00:45
loolIf I come across them, I'll post them your way00:48

bercoI heard there's a magic launchpad ppa where I can find debug versions of packages... where is that? Looking for libasound2-dbg package09:51
persiaIt's not a ppa.09:53
* persia verifies that armel ddebs are present09:54
persiaYeo.  Just add "deb http://ddebs.ubuntu.com/" to your sources.list09:54
persiaAfter that, `apt-get install libasound2-dbgsym` ought work.09:55
bercopersia: thanks, I'm going to try that, sounds good09:55
persiahttp://ddebs.ubuntu.com/pool/main/a/alsa-lib/libasound2-dbgsym_1.0.23-1ubuntu2_armel.ddeb is the file you want, if you want it for some other reason09:56
hrwpersia: how libasound2-dbgsym differ from libasound2-dbg?09:57
persiahrw, It's a matter of packaging.09:58
hrwok09:58
persiaIf pkg-create-dbgsyms is installed on the buildd, when dh_strip runs, it creates the -dbgsym ddeb automatically.09:58
persiaIf the packager chooses to override dh_strip to create a -dbg package, it doesn't do this, and the -dbg packages sits in the normal archives.09:58
persiaPersonally, I prefer that folks do not create -dbg packages, as it clutters mirrors for a rare use case.09:59
persiaMind you, I felt the other way before pkg-create-dbgsym existed, and I'm still undecided which is the best approach in Debian, but for Ubuntu, not creating it is cleaner.09:59
bercopersia: thanks a lot for the detailed explanation :)10:00
persiaberco, No problem.  I'm always happy to answer questions in arbitrary detail where I know the answer.10:02
hrwpersia: thx10:03
cwilluhas rcn been seen lately?10:10
hrw~seen marcos10:12
cwilluhrw, is there an implication I'm to infer from that? :)10:13
* cwillu checks his log10:14
cwilluwow, I've managed to miss him... every day for the last 2 weeks10:14
hrwcwillu: no, I just have a question to markos10:15
cwilluokay10:15
hrwdavidm: hi10:24
davidmHello10:28
hrwdavidm: you are at London now?10:31
jo-erlenddoes anyone know the power consumption of OMAP4 compared with OMAP3?10:32
cwillu_at_workjo-erlend, might have more luck in #beagle, I know there's some ti guys that hang around there (not sure if they're here too)10:33
davidmhrw, Yes I'm in London now10:34
hrwjo-erlend: #beagle and #pandaboard in ~6h from now - ask TI people10:34
hrwjo-erlend: timezone differences kill10:35
* hrw bootstraps armelhf toolchain10:35
jo-erlendthanks for the advise. On the release party for Maverick in Oslo, we'll focus on Green IT, and in that context I'll present the igepv2. Thought it'd be nice to talk a little about the future as well.10:36
hrwjo-erlend: pandaboard for sure is nicer desktop replacement then igep. and both should take <20W fully equipped10:37
amitkjo-erlend: power work is still WIP for OMAP4 and I don't think any public numbers are shared with comparisons between omap 3 & 410:37
hrwwhere fully equipped for me means: board, keyboard, mouse, some networking (ethernet/wifi), some storage10:38
rsalvetimopdenacker: nice, good to know if also worked fine for you :-)14:45
rsalvetindec: mopdenacker: are we going to have the usual call?14:46
mopdenackerhi rsalveti ! No, I believe that the call is cancelled this week...14:46
ndecrsalveti: no. i tried to cancel the meeting... but I think something got messed up with TI exchange server ;-) did you receive the cancellation?14:46
rsalvetindec: not yet, but my network here sucks14:46
rsalveticool, just to know :-)14:47
ndecrsalveti: ok... so please pass the message around in case some did not get it14:47
rsalvetindec: sure, thanks14:47
ndecrsalveti: ogra: the customization of pre installation worked like a charm! even with kernel upgrade. so we have pre installed image with all TI packages! and wifi work right after install14:48
rsalvetindec: awesome :-)14:48
mopdenackerThat's very cool. Now we know how to do all this with other boards (in private projects, don't worry, there are no new OMAP4 boards to support) ;-)14:51
ogra_acndec, wohoo !!!14:52
=== zyga is now known as zyga-lunch
ndecogra: next step is flash the .img in eMMC and boot without SD card ;-014:53
ogra_acthats for natty though :)14:53
ogra_acbut we'll solve it14:53
ndecwell.. we have to do it for maverick... all our releases need to work from emmc14:53
ndecso we will do something short term, until a better solution is there.14:54
ogra_acndec, well, create a little script that tars up the rootfs while running from it (make sure to exclude all tmpfs mounts), fire up a partitioning tool, partition, untar ...14:56
rsalvetiyeah, same thing if you want to use with external usb14:57
ndecogra_ac: we could do this in initrd at first boot before resizing, right?14:58
ogra_acndec, hmm, that would work but would be slow14:58
ndecthen we would resize the emmc or any other external drive, and continue installation14:58
ogra_acyep14:58
ogra_acwill require some hacks to jasper14:58
ndecwhy would that be slower than what you proposed?14:58
ndecyou could have an extra param in boot.scr such as relocateroot=/dev/xxx14:59
ogra_acndec, not slower just more annoying :) what i proposed would run from a running system so the user couls play solitaire while it copies :)15:00
ndecogra: let's fire solitaire in ascii from initrd then...15:01
ogra_achaha15:01
ogra_acndec, well, seriously i dont think it matters where you run the copying so jasper seems to be a good place15:02
ndecogra: when you resize the partition to you erase partitions that might exist, or do you just use free space?15:02
davidmogra_ac, is the TI call happening today?15:02
rsalvetidavidm: nops, canceled15:02
ogra_acndec, when the resizing runs the mbr and partition table were already overwritten by your zcat/dd15:02
davidmOK thanks15:02
ndecwell, but for emmc, if I have /dev/mmclk0p1 and /dev/mmcblk0p2 on emmc. and I try to relocate to one of them, will jasper remove the other partition?15:03
ogra_acndec, so there are no partitions i need to care about in the SD case ... for eMMC you need to come up with something ... a question or some such15:03
ogra_acjasper wont remove anything15:03
ogra_achmm15:03
ndecdavidm: sorry.. tried to cancel the meeting request.. but ubuntu/thunderbird does not like our exchange server... or maybe the other way around.15:03
ogra_acthough probably it would15:04
ogra_acsince we forcefully create the new partition table15:04
davidmndec, NP15:04
lag"Thank you for holding. Please wait for the chair person to join" Arrrrrrrrrrrrrrrrrrrrrrrrr15:08
ogra_acndec, i got "Annulé: Ubuntu / OMAP working group weekly" in my inbox15:09
ogra_acso it partially worked at least15:09
ndeclag: no call today ;-)15:10
lagThanks for the email ;)15:10
ndecogra: yes. for someone that knows a little of French at least!15:10

ogra_acthats odd16:41
lrgogra: I cant get past the welcome screen due to this16:41
lrgyeah, seems very odd16:41
* ogra_ac has never seen such behavior16:41
lrgafaik, I'm the only one with this behaviour16:42
ogra_acare you sure its a 2.0 ?16:42
ogra_acwe dropped support for 1.016:42
lrgyeah, green board - Rama confirmed16:42
lrggot it last week16:42
ogra_ack16:42
ogra_acwell, there are several 1.0 that are green too16:43
ogra_acdoes it have a wlan chip ?16:43
ogra_ac(1.0 didnt)16:43
lrgyes16:43
ogra_ack16:43
ogra_acthen its definitely 2.016:43
lrgeverything failing is on the LAN/USB connector16:44
ogra_acand green means 8 layer ... that should just work16:44
ogra_acwe tested here for the whole week16:44

cwillu_at_workstill in the kernel business?22:46
cwillu_at_workincidently, if anyone is talking about btrfs on sd, 2.6.37 is going to improve some matters22:46
rcn-eeyeah..  well not today, pulling the 302 out of my mustang. ;) do they have anything different from mainline btrfs?22:47
cwillu_at_workwhich, .37, or the mustang?22:48
cwillu_at_workI have an ecu from a '90 miata sitting on my desk, if that counts for anything22:48
rcn-eeyeah, i have the mainline 2.6.36-rc7 built..  was there more for btrfs that you were looking at.. ;)22:48
cwillu_at_workactually, that's not a bad version22:49
rcn-eeit's only a couple days old too. ;)22:50
cwillu_at_work2.6.37 should have raid5/6, and also shared block allocations for small devices such that enospc issues are gone22:50
