| 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)? | 04:53 |
|---|---|---|
| lilstevie | probably not :p | 05:01 |
| twb | Good-o, because it isn't for me | 05:05 |

| janimo | marvin24, so the 3.1 ubuntu kernel's CONFIG_PROFILING should be off? | 07:35 |
| janimo | btw do you use for-next with defconfig? that did not boot for me on Friday | 07:35 |
| janimo | I see you made an update since | 07:35 |
| marvin24 | janimo: it boots | 07:51 |
| marvin24 | did you concatenate the compiled device tree to it? | 07:51 |
| marvin24 | paz00_defconfig should be fine | 07:51 |
| marvin24 | for the 3.1 kernel ... | 07:51 |
| marvin24 | I tried it on my local branch (which is source identical to the package tree) | 07:52 |
| marvin24 | the strange thing is, disabling PROFILING helps with my own tree | 07:52 |
| marvin24 | but after building the package, it still doesn't work (same config of course) | 07:52 |
| marvin24 | also the binaries are different | 07:54 |
| marvin24 | and yes, I double checked that the source and config is identical | 07:54 |
| marvin24 | mmh, thing about it, the package used the hf compiler | 07:55 |
| janimo | yes I use the hf compiler only lately, 4.6 | 07:58 |
| 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 | 07:58 |
| janimo | marvin24, what I see when googling is make zimage, cat boar.dt >>zImage;make uImage | 08:09 |
| janimo | but that is for uboot | 08:09 |
| janimo | or wait, the current ac100 bootloader cannot boot DT kernels? | 08:09 |
| marvin24 | janimo: it can, but the device tree needs to be added to the kernel | 08:24 |
| marvin24 | for u-boot, device tree can come from the bootloader | 08:24 |
| marvin24 | you need to do a make zImage dtbs | 08:25 |
| marvin24 | and then cat arch/arm/boot/tegra20-paz00.dtb >> arch/arm/boot/zImage | 08:25 |
| janimo | marvin24, so you make a generic zimage and cat as many board DT files as you want it to be able to support? | 08:26 |
| marvin24 | no, only one | 08:26 |
| marvin24 | ideally, the bootloader supplied the device tree | 08:27 |
| marvin24 | but ours can't right now | 08:27 |
| marvin24 | but this will change with uboot | 08:27 |
| janimo | ah, so the same kernel booting does not mean an exact same blob but a same zImage + custom DTs | 08:27 |
| marvin24 | so you can directly boot the same kernel on different boards | 08:27 |
| marvin24 | yes | 08:27 |
| janimo | ok, by same kernel initially I though one binary. This works too though | 08:27 |
| janimo | will try it out once the build finishes | 08:28 |
| marvin24 | I think it must be similar on omap | 08:28 |
| janimo | marvin24, also isn't nvec a generic driver for all tegra ECs? | 08:28 |
| janimo | I see only paz00 uses nvec | 08:28 |
| janimo | do the others use other EC implementations? | 08:28 |
| marvin24 | the ec is not inside the tegra | 08:28 |
| marvin24 | but somewhere else | 08:28 |
| marvin24 | so it is board specific | 08:28 |
| janimo | so only the communication protocol is common? | 08:29 |
| marvin24 | there are other "first gen" board using nvec | 08:29 |
| janimo | I just grepped the dt files for nvec | 08:29 |
| marvin24 | we (and trimslice) are the only non nvidia board supported by mainline kernel | 08:29 |
| marvin24 | so there is no wonder why we are the only user ;-) | 08:30 |
| janimo | so other ECs do not necessarily use the same SMBus protocol as described in the nvdia docs | 08:30 |
| marvin24 | yes | 08:30 |
| janimo | I thought tegra somehow implied nvec | 08:31 |
| marvin24 | toshiba folio uses it for power supply readings | 08:31 |
| marvin24 | same for advent vega | 08:31 |
| marvin24 | but unfornately, they have their own implementations | 08:32 |
| marvin24 | janimo: if you feel lucky today, you can also try https://gitorious.org/uboot-ac100 with this kernel ;-) | 08:33 |
| janimo | marvin24, nice. Do I just build it and flash it to the bootloader partition as an android bootimage? | 08:35 |
| janimo | cloning it now | 08:35 |
| marvin24 | I use tegrarcm to load it to memory | 08:36 |
| marvin24 | I think that's the best way for now, because flashing it to emmc is a bit more complicated | 08:36 |
| marvin24 | http://nv-tegra.nvidia.com/gitweb/?p=tools/tegrarcm.git;a=summary | 08:37 |
| marvin24 | but you need the bct first ... | 08:37 |
| marvin24 | (the first 4080 byte of the bct partition #2 I think) | 08:39 |
| janimo | marvin24, mainline boots showing two penguins qwith blue beaks and feet, then cannot find root, but impressive still :) | 09:05 |
| marvin24 | janimo: needs to boot from sd card | 09:05 |
| ogra_ | whats impressive ? the penguins ? :P | 09:05 |
| janimo | the fact it boots :) | 09:05 |
| marvin24 | ogra_: maybe the blue feets | 09:05 |
| janimo | marvin24, why sdcard? no mmc suport implemented? | 09:06 |
| marvin24 | janimo: there is some bug in the drm driver which causes color switch | 09:06 |
| marvin24 | janimo: no nvidia partition support | 09:06 |
| ogra_ | marvin24, well, penguins live on ice :) | 09:06 |
| marvin24 | I could add it though | 09:06 |
| ogra_ | you mean we could use mainline with just one patch added ? | 09:06 |
| ogra_ | or is there more that doesnt work | 09:07 |
| janimo | that's what I was hoping but marvin24 said no way yet :) | 09:07 |
| ogra_ | what else is missing ? nvec ? | 09:07 |
| marvin24 | ogra_: we need the drm support (one patch) and optional partition support | 09:07 |
| marvin24 | everything else is there | 09:08 |
| ogra_ | hmm, so three then | 09:08 |
| janimo | power management? | 09:08 |
| marvin24 | not yet | 09:08 |
| ogra_ | aha | 09:08 |
| ogra_ | k, that somewhat rules it out for now then | 09:08 |
| marvin24 | ogra_: but it is boot | 09:08 |
| marvin24 | *booting | 09:08 |
| ogra_ | (as a default) | 09:08 |
| marvin24 | ogra_: don't you have a nvec-leds entry in sysfs? | 09:26 |
| ogra_ | i didnt look :P | 09:26 |

| janimo | ogra_, too much hardware in the blogpost for my taste but still good :) | 12:32 |
| ogra_ | i should have scattered more cute panda pics all over the place i guess :) | 12:35 |
| lilstevie | ogra_, that is damn cool | 13:33 |
| ogra_ | :) | 13:33 |
| rsalveti | ogra_: you need to enable facebook/g+ sharing at your wordpress blog, can't share directly from your post :-) | 13:34 |
| rsalveti | but it's shared at g+ now :-) | 13:34 |
| ogra_ | heh, thx | 13:34 |
| ogra_ | i dont have a fecaebook account and dont plan to get one | 13:35 |
| ogra_ | (do i ned one to enable the sharing) ? | 13:36 |
| ogra_ | G+ enabled now | 13:37 |
| rsalveti | ogra_: nops | 13:37 |
| rsalveti | ogra_: you just enable the sharing plugin at wordpress for it | 13:38 |
| ogra_ | ok | 13:38 |
| ogra_ | added too now | 13:39 |
| FunkyPenguin | anyone know if u-boot in precise supports extload? | 15:04 |
| ogra_ | should, yep | 15:05 |
| ogra_ | i think all ubuntu versions since lucid do ... | 15:05 |
| FunkyPenguin | thanks, i'll give it a go and see | 15:07 |
| 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 | 15:10 |
| ogra_ | oh, snowball | 15:10 |
| FunkyPenguin | just building the latest 12.07 release and will try that | 15:10 |
| ogra_ | note that ubuntu doesnt have any support for snowball beyond what linaro puts in the archive | 15:10 |
| ogra_ | so if linaros u-boot doesnt have extload for the snowball enabled, you wont have it | 15:11 |
| ogra_ | i can only speak for all u-boots for the supported ubuntu arches | 15:11 |
| FunkyPenguin | which is omap? | 15:19 |
| ogra_ | omap, omap4, highbank and armadaxp currently | 15:20 |
| ogra_ | and tegra2 ac100 netbooks but there is no u-boot | 15:20 |
| ogra_ | (android based netbook which uses a fastboot based loader) | 15:21 |
| ogra_ | we used to have mx5 images too until precise | 15:22 |
| janimo | ogra in the initial ac100 tarball, where are the hooks that create the new initramfs for the installer reboot? | 15:28 |
| ogra_ | you mean ac100-tarball-installer ? | 15:28 |
| ogra_ | there are no specific initrd hooks, it just runs a chrooted flash-kernel and puts a default initrd in place | 15:29 |
| ogra_ | (it sets MODULES=dep and diverts plymouth and cryptsetup hooks though) | 15:30 |

| zma | ahh, sorry that, I think it's for mainline kernel source | 19:36 |
