| janrinze | hi all, are there people here who have Ubuntu 12.04 installed on a Transformer TF101? i have some questions about powersave and suspend modes | 07:37 |
|---|---|---|
| janrinze | lilstevie: hi, is there any new work done on suspend/resume for the TF101? | 07:38 |
| lilstevie | at the moment? no, I have been busy with uni | 07:38 |
| janrinze | ah. ok | 07:39 |
| janrinze | lilstevie: on Ubuntu 12.04 the screen saver kicks in quite swiftly but after that login is not really possible anymore due to looping.. | 07:40 |
| lilstevie | well then change the settings :) | 07:41 |
| janrinze | true.. | 07:41 |
| lilstevie | tell it not to sleep | 07:42 |
| janrinze | even with that it appears to go to sleep anyway.. | 07:42 |
| lilstevie | the up-to-date tree reboots on sleep | 07:42 |
| lilstevie | wait, are you meaning how on power on it loops | 07:42 |
| janrinze | there is no apm deamon running | 07:42 |
| lilstevie | cause that is pulseaudio crashing lightdm | 07:43 |
| lilstevie | if not, the display turning off looks like sleep | 07:43 |
| janrinze | lilstevie: i am loged in over shh too and that works. however it will drop into powersave afer a few seconds again | 07:43 |
| lilstevie | on initial boot yes? | 07:44 |
| lilstevie | like you haven't logged in yet | 07:44 |
| janrinze | the ssh becomes a bit slow to respond and the screen flips on after i type something in ssh :-) | 07:44 |
| lilstevie | sudo apt-get autoremove pulseaudio | 07:44 |
| janrinze | lilstevie: the pulseaudio is removed already, that was quite a challenge with the login issues :-) | 07:44 |
| lilstevie | ok, disable sleep | 07:45 |
| lilstevie | and it won't go to sleep | 07:45 |
| lilstevie | make sure you tell it to never sleep for both on battery and on ac | 07:45 |
| janrinze | having trouble to do anything at all on the desktop since it keeps cycling.. | 07:46 |
| janrinze | after a reboot all is fine. But once a sleep was initiated it will cycle again | 07:47 |
| lilstevie | yes, so do it before it goes to sleep | 07:47 |
| janrinze | :-) true again | 07:48 |
| lilstevie | I only turn the screen off on my device | 07:48 |
| lilstevie | sleep is turned off entirely | 07:49 |
| janrinze | do you know of other people working on the kernel for the TF101? | 07:49 |
| lilstevie | yes, but I wouldn't trust their kernels on my device :/ | 07:49 |
| janrinze | aha. | 07:50 |
| lilstevie | http://forum.xda-developers.com/showthread.php?t=1683145 welcome to try it though | 07:50 |
| janrinze | lilstevie: what is the best/recent kernel for the tf101? | 07:50 |
| lilstevie | I don't agree with certain things like overclocking to 1.6 by default though | 07:50 |
| janrinze | i am willing to roll my own ;-) | 07:50 |
| janrinze | overclocking is not my aim.. stability is | 07:51 |
| lilstevie | well there is https://github.com/lilstevie/linux_kernel_TF101 | 07:51 |
| lilstevie | that is the one I have running | 07:51 |
| lilstevie | sleep looping is not an issue cause it will reboot :p | 07:51 |
| janrinze | ok. i have Linux Tegra2 2.6.36.4 #5 SMP PREEMPT Fri Nov 4 22:21:17 EST 2011 armv7l armv7l armv7l GNU/Linux | 07:52 |
| janrinze | that one is supplied in your OLiFE Prime package | 07:52 |
| lilstevie | stackprotector is a little touchy and sleep breaks it | 07:52 |
| janrinze | aha | 07:53 |
| janrinze | i have worked on kernels for many ARM devices in the past and sleep was always dodgy.. | 07:53 |
| janrinze | so i am not surprised here ;-) | 07:53 |
| lilstevie | hah | 07:54 |
| lilstevie | sleep worked | 07:54 |
| janrinze | lilstevie: but loops | 07:54 |
| lilstevie | no | 07:54 |
| janrinze | oh, what changed? | 07:55 |
| lilstevie | I mean I had sleep working at one point | 07:55 |
| lilstevie | I recompiled | 07:55 |
| janrinze | aha | 07:55 |
| lilstevie | must have exhaled at the wrong time | 07:55 |
| janrinze | yeah, i know what you mean.. | 07:55 |
| lilstevie | because now it will not | 07:55 |
| janrinze | is there stuff going upstream to main kernel? | 07:55 |
| janrinze | would be nice to recompile a kernel from kernel.org and run that ;-) | 07:56 |
| lilstevie | not likely | 07:56 |
| janrinze | 2.6.36.4 is good enough for what i need a.t.m. so i might take a shot at building from your git repo | 07:57 |
| lilstevie | heh | 07:57 |
| janrinze | i have a lot of ARM boards laying around but none of them are Tegra 2. | 07:57 |
| lilstevie | as long as it gets the device booting right | 07:57 |
| janrinze | yeah | 07:57 |
| janrinze | usually fbdev + usb is my main concern | 07:58 |
| lilstevie | well fbdev and usb work :p | 07:58 |
| janrinze | if that works (and networking of course) I can get most things working. | 07:58 |
| lilstevie | yeah | 07:58 |
| lilstevie | I can work with a little less :p | 07:59 |
| janrinze | did uboot get any further? | 07:59 |
| lilstevie | uboot is a pointless dead end :) | 07:59 |
| janrinze | oh. because booting from a separate SDcard would be interesting. | 07:59 |
| lilstevie | yeah, well we have been working on some stuff using kexecboot which has been promising | 08:00 |
| lilstevie | at least on the tf201 | 08:00 |
| janrinze | is kexec not working on tf101? | 08:00 |
| lilstevie | well tf201 has been higher priority cause I haven't officially released anything for that one yet | 08:01 |
| lilstevie | :) | 08:01 |
| janrinze | lilstevie: have you tried kexec on the tf101? | 08:23 |
| janrinze | lilstevie: # CONFIG_KEXEC is not set .. from /proc/config.gz :-( | 08:24 |
| lilstevie | if only it were that simple :p | 08:37 |
| lilstevie | there is hardware that will not handle a kexec | 08:38 |
| lilstevie | well, more the drivers are not built for it | 08:38 |
| janrinze | hmm.. the tf101 specific drivers won't survive kexec.. ok | 08:39 |
| lilstevie | we are using a derivation of http://forum.xda-developers.com/showthread.php?t=1266827 | 08:39 |
| lilstevie | we don't know what parts are not surviving cause it prevents the kernel being kexec'd to from booting | 08:40 |
| lilstevie | but that hardboot works fine | 08:40 |
| janrinze | if hard-boot works fine then i can kexec with args to boot from SDcard :-) | 08:41 |
| lilstevie | you can boot from sdcard now | 08:41 |
| lilstevie | you just need to edit the bootimg.cfg for the kernel image | 08:42 |
| janrinze | how? that was not in the wiki nor in the readme | 08:42 |
| janrinze | ah, but that is statically changing the pootparams | 08:42 |
| janrinze | bootparams are flashed with nvflash.. right? | 08:42 |
| lilstevie | no | 08:42 |
| lilstevie | with the bootimg | 08:42 |
| lilstevie | which can be flashed from userspace too | 08:43 |
| janrinze | hm.. interesting.. | 08:43 |
| janrinze | lilstevie: dd from and to the bootimg partition i guess | 08:44 |
| lilstevie | no | 08:44 |
| janrinze | mount it? | 08:45 |
| lilstevie | packing into a blob and dding to the staging partition | 08:45 |
| lilstevie | boot partition is outside of the partition table | 08:45 |
| lilstevie | bootloader is responsible for flashing it | 08:45 |
| janrinze | the blob packer is new to me. most systems i use have u-boot so i can work with that quite well.. | 08:46 |
| janrinze | lilstevie: which partition is the staging partition? | 08:47 |
| lilstevie | mmcblk0p4 | 08:47 |
| janrinze | i have that mounted under ext3 | 08:47 |
| janrinze | so putting the bootimg in there would suffice? | 08:48 |
| lilstevie | no | 08:48 |
| janrinze | and resetting the device of course | 08:48 |
| lilstevie | it shouldn't be mounted | 08:48 |
| lilstevie | just dd straight to it | 08:48 |
| janrinze | ok, will try that once i have built the kernel. | 08:49 |
| janrinze | lilstevie: when shutting down while in android i chose 'restore' option which now makes linux the default to boot. :-) | 08:50 |
| lilstevie | heh as long as you remember to clear the tag | 08:51 |
| lilstevie | also blobs will not flash if there is a tag in misc | 08:51 |
| janrinze | i also did a 'wipe' which cleaned out the other partitions and they now show up in Linux as 4 partitions | 08:51 |
| lilstevie | system, cache and data will always | 08:53 |
| janrinze | is that the misc dir in mmcblk0p7 ? | 08:55 |
| janrinze | lilstevie: /dev/fb1 is that a second framebuffer for hdmi output? | 09:01 |
| lilstevie | misc is mmcblk0p3 like the whole thing | 09:17 |
| lilstevie | and fb1 is the second framebuffer | 09:17 |
| janrinze | oh. ok :-) | 09:17 |
| lilstevie | doesn't always mean hdmi but in this case yes | 09:18 |
| lilstevie | tegra fb1 can be hooked up to a few different busses | 09:18 |
| janrinze | i was thinking to use that as a second monitor :-) | 09:18 |
| janrinze | hopefully to get it to output 1920x1080 | 09:19 |
| lilstevie | without the tegra proprietary drivers that isn't happening :) | 09:24 |
| janrinze | :-( | 09:24 |
| janrinze | so 1280x720 should at least be possible or does it mean no hdmi at all? | 09:24 |
| lilstevie | no hdmi at all | 09:25 |
| janrinze | :( !! | 09:26 |
| janrinze | how do the tegra drivers (beta releases) fit in there? | 09:26 |
| janrinze | nvidia seems to provide some | 09:26 |
| lilstevie | incompatible with the kernel | 09:27 |
| janrinze | ok. so i would need a different kernel then. 3.x ? | 09:27 |
| lilstevie | you would need a kernel that works on the device | 09:27 |
| lilstevie | that has the interface | 09:28 |
| lilstevie | that one I linked to before does | 09:28 |
| lilstevie | but as I said I wouldn't trust it on my device | 09:28 |
| lilstevie | if for no reason other than it burns the cpu at 1.6GHz | 09:28 |
| lilstevie | (I do have other reasons though) | 09:28 |
| janrinze | ok. i can understand | 09:29 |
| janrinze | best would be then to get those sources and remove the 1.6 GHz stuff and build | 09:29 |
| janrinze | will look into that. | 09:29 |
| janrinze | lilstevie: do you know why/if XShm is supported? i get an error : X Error of failed request: BadAccess (attempt to access private resource denied) | 09:47 |
| lilstevie | hm | 09:51 |
| lilstevie | not seen that | 09:51 |
| janrinze | i have a program that uses XShm, it is not from Ubuntu | 09:52 |
| janrinze | http://code.google.com/p/rtviewer/ | 09:53 |
| janrinze | lilstevie: ipcs shows that the kernel is not configured for shared memory, semaphores and message queues! | 17:19 |
| === jkridner_ is now known as jkridner | ||
| janrinze | lilstevie: you still here? | 20:33 |
