xnoxogra_: do you have a bug # handy of the "can't type in the fields in oem-config but works elsewhere"20:20
topi`quick q: i'm considering getting a samsung chromebook and installing raring on it. do the chromeOS suspend/resume bugs affect ubuntu as well?20:25
ogra_xnox, heh, funny coincidence ...20:28
ogra_xnox, watch your bugmail. i just duplicated one to the master bug20:29
ogra_bug 109305020:29
ubot2Launchpad bug 1093050 in ubuntu-nexus7 "compiz dies during oem-config and steals the focus so that input fields are unusable" [High,Confirmed] https://launchpad.net/bugs/109305020:29
ogra_i thought i made the description clear enough, but just searched my butt off to find it again ...20:30
xnoxogra_: thanks, i was pinged about the one you marked as duplicate on #ubuntu-quality ;-)20:30
ogra_heh20:31
marvin24is the omap u-boot device tree the same as the kernel one?20:32
marvin24I wonder how to pass the device tree to u-boot on tegra20:32
ogra_ppisati, ^^^20:33
marvin24btw, it's maybe not a clever choice to put device tree outside of /boot if you want to load it20:33
ppisatimarvin24: you mean the DTB file? it's build from kernel source so yes20:33
ppisati*built20:33
marvin24ppisati: you mean it is build into the kernel?20:34
ppisatimarvin24: nope20:34
ppisatimarvin24: it's in...20:34
ppisatimarvin24: wait20:34
marvin24I know it is inside the kernel source20:34
marvin24but you need to pass it to the kernel on boot20:34
ppisatimarvin24: right20:34
marvin24either you compile it in (bad)20:35
marvin24or you load it with uboot20:35
ppisatimarvin24: it's not compiled in20:35
marvin24ppisati: so how is it loaded?20:35
ppisatimarvin24: we are switching to a multiplatform kernel (omap3/4, freescale imx6 and vexpress)20:35
marvin24yes, even with single platform (multi-soc) you need to load it20:35
ppisatimarvin24: you manually modify uboot.scr or uenv.txt (or the other don't remember)20:36
ppisatimarvin24: wait20:36
ppisatimarvin24: and add20:36
marvin24I haven't found this in flash-kernel20:36
ppisatimarvin24: "fatload mmc 0:1 0x82600000 board.dtb"20:36
marvin24that's why I asked20:36
ppisatimarvin24: "bootm ... ... 0x82600000"20:36
ppisatimarvin24: our flash-kernel doesn't support DTB20:36
ppisatimarvin24: you need to do the modification manually20:37
marvin24oh20:38
marvin24so hard coded in u-boot ...20:38
ppisatimarvin24: you can modify the loader script and rebuild (boot.scr) or just modify/update it (uenv.txt&c)20:39
marvin24boot script is in /usr/share/... and should not be modified20:39
marvin24and uenv.txt is kinda non standard, but ok20:40
marvin24if that's that way to go20:40
marvin24ppisati: still, dtb in /lib/firmware/device-tree is not so nice20:41
ppisatimarvin24: there was something in /etc/...20:41
marvin24if you have a /boot partition20:41
ppisatimarvin24: uh?20:41
ppisatiyu copy it to the fat partition and you load it from there20:41
ppisatimarvin24: that's what flash-kernel should do20:41
marvin24there is /etc/defaults/flash-kernel or so which can be enhanced20:41
ppisatimarvin24: but (unfortunately) doesn't20:42
marvin24ah, copy20:42
marvin24I did it by hand20:42
marvin24yes, also missing in flash-kernel20:42
ppisatimarvin24: watch out that if you are running an old version of u-boot it doesn't support dtb20:44
marvin24ppisati: it's already booting (2013.01)20:46
marvin24just need to fix up the last things (e.g. flash-kernel)20:46
qenghotopi`: I have a Chromebook that's a few months old.  Has Precise, which does not suspend.  I don't know about Raring.20:51
ogra_qengho, apparently hrw's kernel in raring is supposed to suspend20:54
ogra_i havent found the time to try it yet20:54
qenghoNice.  I have a reason to upgrade, then.20:54
* ogra_ runs raring userspace but still the original kernel20:55
topi`qengho: have you tested if suspend works in chromeOS?21:07
topi`I just read that there are problems suspending in chromeOS21:08
topi`doesn't ubuntu use the same kernel?21:08
ogra_worked in the original chromeos install for me21:08
topi`ogra_: sounds better than the suspend reliability in AC100, then ;)21:09
ogra_well, in ubuntu it reliably doesnt suspend  with that kernel21:09
topi`wife wants an absolutely quiet netbook, so I'm probably shelling out some $$$ for chromebook21:09
ogra_and if i upgrade i'll likely lose dualboot21:09
topi`how does dualboot work then?21:10
ogra_and while flash from chromeone works flawless in ubuntu chromium, the hangout plugin doesnt21:10
topi`I know nothing of samsung bootloader21:10
ogra_painful21:10
qenghotopi`: not the same kernel, exept in the narrowest sense as in "your television uses the same kernel as your Android phone".21:10
ogra_you need to switch back from developer mode to boot back int chrOS21:10
topi`interesting21:11
ogra_qengho, i currently use the exact same kernel here21:11
topi`I knew ogra would ;)21:12
topi`ogra_: I bet you must already be playing with some nice Aarch64 boards already ;)21:12
ogra_nah, #ubuntu-touch toptally sucked me in21:13
topi`you guys get all those fancy devices a year earlier than us mortals21:13
topi`ouch...21:13
ogra_and the boards nowadays go rather to linaro21:13
topi`I was (slightly) involved in the touchscreen driver for the Nokia N(21:13
topi`N921:13
ogra_well, ubuntu touch bases on CWM 10.1 ...21:15
ogra_so there are no drivers to touch, they just work21:15
topi`ok21:15
ogra_23 ports to other devices underway after 5 days ... https://wiki.ubuntu.com/Touch/Devices21:19
xnoxogra_: are they merged? are they legal to be merged?21:21
ogra_not yet merged, not sure what the plan is on merging, but there are images that you can just use with our userspace image21:21
xnoxawesome!21:22
ogra_i think its absolutely legal21:22
xnoxif the userspace image is detached than I can see how we don't have to merge anything, apart from possibly make pointers to android repo git forests URL (either straight from android.com or with some patches applied in forked github repos)21:23
xnoxs/detached/independ of base-hw image/21:23
ogra_yeah21:24
ogra_porting is largely just copy paste work and a successfull compile run21:24
xnoxoh, so we could automate it =) e.g. by hosting a repository with android-repo manifests URLs pointing to the right places.21:25
ogra_well, until you run into build issues21:26
ogra_but yeah, you could just rip the snippets out of CWM21:26
infinityogra_: s/CWM/CM/ I assume?21:27
ogra_err, yes21:27
* infinity was trying to sort out how ClockWork factored into this.21:28
ogra_heh, i'm just learning all the android l33tspeak and names, bear with me :)21:28
XorAogra_: hehe, learning to optimize by changing the wallpaper then?21:31
ogra_lol21:31
XorAmy Android devices seem to get stuck on stock roms, Optimize too often means break ;-)21:32
ogra_well, we only use the kernel and driver layers (HAL, surfaceflinger etc) ... the rest is a plain ubuntu rootfs21:34
ogra_so as long as androind HW layer doesnt suck performance wise ....21:34
XorAwould need one of these funky modern devices I guess to try ubuntu-touch21:35
ogra_well, yeah, dualcore and 1G is currently a requirement ...21:43
ogra_i doubt you would have aany fun below that21:44
marvin24ppisati: I guess I will just change the kernel package to copy the relevant device tree to /boot/device-tree.dtb based on /proc/device-tree/model instead of poking around with flash-kernel21:48
ogra_++21:49
ogra_its not like they change or anything21:49
XorAogra_: my phone is an Xperia Play :-D so just a little old :-D21:50
