**** BEGIN LOGGING AT Mon Aug 06 02:59:58 2012
Aug 06 04:53:02 <twb> lilstevie: quick question -- is XV supposed to work on the TF101, using the oooold oneiric armel images you built (and the android 2.6.36 kernel)?
Aug 06 05:01:41 <lilstevie> probably not :p
Aug 06 05:05:44 <twb> Good-o, because it isn't for me
Aug 06 07:35:17 <janimo> marvin24, so the 3.1 ubuntu kernel's CONFIG_PROFILING should be off?
Aug 06 07:35:37 <janimo> btw do you use for-next with defconfig? that did not boot for me on Friday
Aug 06 07:35:42 <janimo> I see you made an update since
Aug 06 07:51:22 <marvin24> janimo: it boots
Aug 06 07:51:40 <marvin24> did you concatenate the compiled device tree to it?
Aug 06 07:51:53 <marvin24> paz00_defconfig should be fine
Aug 06 07:51:58 <marvin24> for the 3.1 kernel ...
Aug 06 07:52:20 <marvin24> I tried it on my local branch (which is source identical to the package tree)
Aug 06 07:52:38 <marvin24> the strange thing is, disabling PROFILING helps with my own tree
Aug 06 07:52:50 <marvin24> but after building the package, it still doesn't work (same config of course)
Aug 06 07:54:03 <marvin24> also the binaries are different
Aug 06 07:54:23 <marvin24> and yes, I double checked that the source and config is identical
Aug 06 07:55:09 <marvin24> mmh, thing about it, the package used the hf compiler
Aug 06 07:58:22 <janimo> yes I use the hf compiler only lately, 4.6
Aug 06 07:58:53 <janimo> marvin24, concatenate DT to it? I never built DT kernel before so I did not know something extra is needed that make zImage does not do
Aug 06 08:09:17 <janimo> marvin24, what I see when googling is make zimage, cat boar.dt >>zImage;make uImage
Aug 06 08:09:24 <janimo> but that is for uboot
Aug 06 08:09:43 <janimo> or wait, the current ac100 bootloader cannot boot DT kernels?
Aug 06 08:24:44 <marvin24> janimo: it can, but the device tree needs to be added to the kernel
Aug 06 08:24:54 <marvin24> for u-boot, device tree can come from the bootloader
Aug 06 08:25:06 <marvin24> you need to do a make zImage dtbs
Aug 06 08:25:30 <marvin24> and then cat arch/arm/boot/tegra20-paz00.dtb >> arch/arm/boot/zImage
Aug 06 08:26:34 <janimo> marvin24, so you make a generic zimage and cat as many board DT files as you want it to be able to support?
Aug 06 08:26:47 <marvin24> no, only one
Aug 06 08:27:03 <marvin24> ideally, the bootloader supplied the device tree
Aug 06 08:27:12 <marvin24> but ours can't  right now
Aug 06 08:27:22 <marvin24> but this will change with uboot
Aug 06 08:27:28 <janimo> ah, so the same kernel booting does not mean an exact same blob but a same zImage + custom DTs
Aug 06 08:27:32 <marvin24> so you can directly boot the same kernel on different boards
Aug 06 08:27:44 <marvin24> yes
Aug 06 08:27:53 <janimo> ok, by same kernel initially I though one binary. This works too though
Aug 06 08:28:00 <janimo> will try it out once the build finishes
Aug 06 08:28:21 <marvin24> I think it must be similar on omap
Aug 06 08:28:25 <janimo> marvin24, also isn't nvec a generic driver for all tegra ECs?
Aug 06 08:28:33 <janimo> I see only paz00 uses nvec
Aug 06 08:28:42 <janimo> do the others use other EC implementations?
Aug 06 08:28:43 <marvin24> the ec is not inside the tegra
Aug 06 08:28:47 <marvin24> but somewhere else
Aug 06 08:28:52 <marvin24> so it is board specific
Aug 06 08:29:07 <janimo> so only the communication protocol is common?
Aug 06 08:29:09 <marvin24> there are other "first gen" board using nvec
Aug 06 08:29:21 <janimo> I just grepped the dt files for nvec
Aug 06 08:29:53 <marvin24> we (and trimslice) are the only non nvidia board supported by mainline kernel
Aug 06 08:30:02 <marvin24> so there is no wonder why we are the only user ;-)
Aug 06 08:30:47 <janimo> so other ECs do not necessarily use the same SMBus protocol as described in the nvdia docs
Aug 06 08:30:57 <marvin24> yes
Aug 06 08:31:00 <janimo> I thought  tegra somehow implied nvec
Aug 06 08:31:30 <marvin24> toshiba folio uses it for power supply readings
Aug 06 08:31:41 <marvin24> same for advent vega
Aug 06 08:32:04 <marvin24> but unfornately, they have their own implementations
Aug 06 08:33:36 <marvin24> janimo: if you feel lucky today, you can also try https://gitorious.org/uboot-ac100 with this kernel ;-)
Aug 06 08:35:32 <janimo> marvin24, nice. Do I just build it and flash it to the bootloader partition as an android bootimage?
Aug 06 08:35:36 <janimo> cloning it now
Aug 06 08:36:02 <marvin24> I use tegrarcm to load it to memory
Aug 06 08:36:31 <marvin24> I think that's the best way for now, because flashing it to emmc is a bit more complicated
Aug 06 08:37:35 <marvin24> http://nv-tegra.nvidia.com/gitweb/?p=tools/tegrarcm.git;a=summary
Aug 06 08:37:50 <marvin24> but you need the bct first ...
Aug 06 08:39:15 <marvin24> (the first 4080 byte of the bct partition #2 I think)
Aug 06 09:05:06 <janimo> marvin24, mainline boots showing two penguins qwith blue beaks and feet, then cannot find root, but impressive still :)
Aug 06 09:05:36 <marvin24> janimo: needs to boot from sd card
Aug 06 09:05:37 <ogra_> whats impressive ? the penguins ? :P
Aug 06 09:05:44 <janimo> the fact it boots :)
Aug 06 09:05:52 <marvin24> ogra_: maybe the blue feets
Aug 06 09:06:03 <janimo> marvin24, why sdcard? no mmc suport implemented?
Aug 06 09:06:05 <marvin24> janimo: there is some bug in the drm driver which causes color switch
Aug 06 09:06:20 <marvin24> janimo: no nvidia partition support
Aug 06 09:06:23 <ogra_> marvin24, well, penguins live on ice :)
Aug 06 09:06:25 <marvin24> I could add it though
Aug 06 09:06:54 <ogra_> you mean we could use mainline with just one patch added ?
Aug 06 09:07:11 <ogra_> or is there more that doesnt work
Aug 06 09:07:21 <janimo> that's what I was hoping but marvin24 said no way yet :)
Aug 06 09:07:49 <ogra_> what else is missing ? nvec ?
Aug 06 09:07:59 <marvin24> ogra_: we need the drm support (one patch) and optional partition support
Aug 06 09:08:09 <marvin24> everything else is there
Aug 06 09:08:22 <ogra_> hmm, so three then
Aug 06 09:08:24 <janimo> power management?
Aug 06 09:08:33 <marvin24> not yet
Aug 06 09:08:36 <ogra_> aha
Aug 06 09:08:45 <ogra_> k, that somewhat rules it out for now then
Aug 06 09:08:46 <marvin24> ogra_: but it is boot
Aug 06 09:08:50 <marvin24> *booting
Aug 06 09:08:59 <ogra_> (as  a default)
Aug 06 09:26:33 <marvin24> ogra_: don't you have a nvec-leds entry in sysfs?
Aug 06 09:26:49 <ogra_> i didnt look :P
Aug 06 12:15:20 <ogra_> http://ograblog.wordpress.com/2012/08/06/the-bamboo-feeder-automating-continuous-arm-image-tests/
Aug 06 12:32:09 <janimo> ogra_, too much hardware in the blogpost for my taste but still good :)
Aug 06 12:35:37 <ogra_> i should have scattered more cute panda pics all over the place i guess :)
Aug 06 13:33:35 <lilstevie> ogra_, that is damn cool
Aug 06 13:33:47 <ogra_> :)
Aug 06 13:34:41 <rsalveti> ogra_: you need to enable facebook/g+ sharing at your wordpress blog, can't share directly from your post :-)
Aug 06 13:34:47 <rsalveti> but it's shared at g+ now :-)
Aug 06 13:34:56 <ogra_> heh, thx
Aug 06 13:35:09 <ogra_> i dont have a fecaebook account and dont plan to get one
Aug 06 13:36:50 <ogra_> (do i ned one to enable the sharing) ?
Aug 06 13:37:05 <ogra_> G+ enabled now
Aug 06 13:37:52 <rsalveti> ogra_: nops
Aug 06 13:38:06 <rsalveti> ogra_: you just enable the sharing plugin at wordpress for it
Aug 06 13:38:12 <ogra_> ok
Aug 06 13:39:30 <ogra_> added too now
Aug 06 15:04:42 <FunkyPenguin> anyone know if u-boot in precise supports extload?
Aug 06 15:05:08 <ogra_> should, yep
Aug 06 15:05:24 <ogra_> i think all ubuntu versions since lucid do ...
Aug 06 15:07:59 <FunkyPenguin> thanks, i'll give it a go and see
Aug 06 15:10:30 <FunkyPenguin> i tried Linaro's 12.05 image on the snowball's emmc but that didnt seem to want to see the sdcard and boot from that
Aug 06 15:10:41 <ogra_> oh, snowball
Aug 06 15:10:46 <FunkyPenguin> just building the latest 12.07 release and will try that
Aug 06 15:10:57 <ogra_> note that ubuntu doesnt have any support for snowball beyond what linaro puts in the archive
Aug 06 15:11:33 <ogra_> so if linaros u-boot doesnt have extload for the snowball enabled, you wont have it
Aug 06 15:11:46 <ogra_> i can only speak for all u-boots for the supported ubuntu arches
Aug 06 15:19:43 <FunkyPenguin> which is omap?
Aug 06 15:20:22 <ogra_> omap, omap4, highbank and armadaxp currently
Aug 06 15:20:35 <ogra_> and tegra2 ac100 netbooks but there is no u-boot
Aug 06 15:21:01 <ogra_> (android based netbook which uses a fastboot based loader)
Aug 06 15:22:44 <ogra_> we used to have mx5 images too until precise
Aug 06 15:28:19 <janimo> ogra in the initial ac100 tarball, where are the hooks that create the new initramfs for the installer reboot?
Aug 06 15:28:51 <ogra_> you mean ac100-tarball-installer ?
Aug 06 15:29:32 <ogra_> there are no specific initrd hooks, it just runs a chrooted flash-kernel and puts a default initrd in place
Aug 06 15:30:30 <ogra_> (it sets MODULES=dep and diverts plymouth and cryptsetup hooks though)
Aug 06 15:30:38 <ogra_> (before doing that)
Aug 06 19:31:25 <zma> I've got a silly question. I'm trying to build kernel I fetched from git://github.com/RobertCNelson/stable-kernel.git , build_kernel script fails in the beginning to complain there is no directory "KERNEL". Am I missing something?
Aug 06 19:36:02 <zma> ahh, sorry that, I think it's for mainline kernel source
