[Info/brainstorming] Compiling modules for the 2.6.32 beta kernel OBSOLETE

This thread is now obsolete.
Kernel sources for build 5.26.0 have been released:
https://opensource.motorola.com/sf/go/projects.milestone/frs.milestone_source_froyo
I've pushed some new pre-compiled modules to github, though beware, I haven't had time to test all of them on device yet:
https://github.com/nadlabak/android...mmit/b300803348705d3fc5ce76d8c88d57186748a370
As the kernel sources are not yet available from the Motorola's open source project, here is an outline how I compiled the overclock and cpufreq governor modules. (Btw., the overclock module needed a substantial adaptation, see the source here: http://android.doshaska.net/2.6.32oc )
I'm using the sources from this AOSP repo:
Code:
git clone git://android.git.kernel.org/kernel/omap.git
git checkout --track -b android-omap-2.6.32 origin/android-omap-2.6.32
Use the sholes config:
Code:
make sholes_defconfig
flags that need to be disabled:
CONFIG_LOCALVERSION_AUTO
CONFIG_MODVERSIONS
CONFIG_DEBUG_MUTEXES
CONFIG_SCHEDSTATS
CONFIG_SCHED_DEBUG
[updated on 17.01.2011, thanks go to Skrilax_CZ]
At least the ext2 will work without panics when compiled using this config.
For tun, cifs and nfs there is still some additional config mismatch that prevents the modules to work without null pointer dereference oops.
Also, even when no custom kernel module is used, you can get the kernel panic very easily, try to enable wifi and do:
Code:
cat /proc/kallsyms
If you're interested in a more detailed android kernel compilation guide, you can e.g. roughly follow this Droid kernel guide: http://www.droidforums.net/forum/rescue-squad-guides/31452-how-compile-your-own-kernel.html

Thanks for starting this thread kabaldan! It is a great starting point in tackling the issue of adding tun support to the new kernel (tun.ko module). I am not as good as many others in this, but trying won't hurt. Meanwhile if someone else is working on tun support - share experience here!

If kernel seems to be ok, sometimes mounting with new version of busybox won't work.
I used to get kernel panic when use newer version of busybox (not Android kernel but my own embedded linux)

Hey Nadlabak can you add DLNA function of CM6?

same problem using droidx kernel sources. insmod ok, mount reboots the phone
yantz

I tried droid2 kernel module - doesn't work either
I noticed OpenVPN included in CM6 also relies on this kernel module. Hence doesn't work. I guess we won't (ever) see kernel sources for that leaked kernel we are now using. I assume Motorola will release the sources sooner or later, but not before official Froyo layout. The waiting is killing me! kabaldan, can't you try to do some magic as you did with the overclock module? The beer is from me!!!

Can you test this attached tun.ko?
Insmod is OK, but I currently don't have time for any further tests...
EDIT: don't bother, kernel panic as usual

Module loads fine, but when attempt to use it, phone reboots, just like with the module compiled from DroidX sources..

So, I got it loaded - insmod works just great, just like it did on the 2.1 kernel.
I'm trying to use the CM6 built-in OVPN settings, but I can't find any documentation on the setup. How did you get it set up?
I have
/sdcard/openvpn/
cert.crt
ca.crt
config.conf
config.ovpn
pem.key
I realize that config.conf and config.ovpn are the same file- but I use this VPN on windows and on Mac, and I wasn't sure the requirements on Linux.
If I can't find some documentation I'll try downloading the OpenVPN settings app from the market and playing with that.
Also, I don't know if it's true or not, but I heard the Milestone2 source compiled driver could work.

Are you trying the module kabaldan provided? It doesn't seem to work, at least for me. Loads fine, but phone crashes when setting up tun interface. I couldn't get OpenVPN in CM6 0.3 to work so far. I am testing the tun.ko with the cisco vpn package (which worked great on the old kernel with CM6 0.2) vpnc. When I initiate the connection, phone reboots if the attached here tun.ko is used. I also tried with tun.ko compiled from DroidX sources - same thing - phone reboots. I am not sure where did kabaldan take/compile this module from.

I was using the same one, I was thinking maybe he could use the info from more than one phone. I'll try get-a-robot or OpenVPN Installer, but I won't hold my breathe. I was just hoping to use the built-in functionality of the ROM.
*edit* Just saw he removed it because it doesn't work yet, oh well.

the kernel doesnt seem to like any other fs not built into it. i've tried several, ext2, ext3, ext4, cifs, jffs, reiserfs etc. all modules would load without a problem but system will reboot during mount. heck i even tried creating logical volume on the partition. volume created fine, but when time to mount, it reboot
i ended up using a 2nd vfat partition for apps2vfat, on top of native froyo move to sd. moved my debian arm there and manually, yes manually, replace many symlinks in libs to copied files
hopefully next froyo release for other regions would provide a different kernel
yantz

hey kabaldan wondering if you've had another chance to look at an updated tun.ko

Finally some breakthrough. The great Skrilax_CZ has made some hard debugging and one very good guess:
CONFIG_DEBUG_MUTEXES must be disabled in the kernel config.
At least the ext2 module compiled this way is working without panics now.
Congrats to Skrilax!
EDIT: Tun nor nfs not tested yet..., cifs unfortunately still not working.

This means that now the app2ext work?
Where are the modules for we test?!
Thanks for the news!

Modules for testing:
ext2 - http://code.google.com/p/cyanogenmod4milestone/issues/detail?id=197#c19
tun - http://code.google.com/p/cyanogenmod4milestone/issues/detail?id=222#c4

Hi sort of a newbie here... So does this mean that data2ext will work?
Sent from my Milestone using XDA App

Hi Nadlabak...maybe you already know.
For the cifs module, how about slow-work is made available as a module.
as is done at this link
http://forum.xda-developers.com/showpost.php?p=9271775&postcount=4

after further testing:
ext2 mounting now works, reading from ext2 partition too, but writing still causes panic
tun causes panic too
Let's hope for a soon kernel source release, as it looks like we won't get much further without it.
edowar: thanks for the link

@kabaldan
Could it be possible to create a swap module for milestone ?
It seems that running kernels does not have this feature yet and i'm not sure motorola to implement it for next 2.2 release so .... well just wondering !

[Q] Can I get some CIFS help? 'cause i'm lost

I'm seriously confused about CIFS...
I'm new to Android, so i'm not sure what tools to use to accomplish certain tasks.
Here's my drama, I'm running TNT lite 3.1.4, i can see the CIFS.co file in the system folders, I set cifs up to use insmod and pointed it at the right path.
I can set up the share but no matter what i do i get a message that says "mounting has failed with an error Mount: no such device".
My shares are hosted on win7 x64 machines and a few Server 2008R2 boxes. If i use ES File Explorer i can see all drives (C$, etc) and explicitly naemd shares (Videos, Documents) but i can only successfully access explicitly named shares (with correct UID/PWD)
The same shares (User, Video, etc) accessed via CIFS yeilds that above error message...
I'm out of ideas. I believe others have this working...any thoughts?

As much as things change around here I may be wrong but I don't think Roebeet put the Cifs kernel into TnTLite. I think that is one of the things he left for the user to patch. There is a Cifs kernel patch for TnTLite in one of these threads that will likely fix what you have going on.. It acts just like that when it is not there... You are using something like CIFS manager to set things up right?

The CIFS module doesn't work with the default TnT kernel - I added it just so the user had it available to them in case they added a customized kernel that could use it.
You should consider it unusable OOTB.

In case you search and don't find it....

I feel kinda dumb now...i saw the thread with the patch but assumed it was only for full STOCK TNT, then when i saw the CIFS.KO file in the TNTlite folders i thought it was active.
I'll try the 3389 CIFS patch on TNT lite (which is what i think is being suggested) and i should be good to go.
thanks all.

Yep.. The latest TnTLite is built from 3389 so the TnT patch will do the trick...

The kernel I posted for TnTL has CIFS built in, thus the kernel module roebeet include is not required. Grab CIFSManager and use UMASK=0755 as the option.

Is that the same as this one?

I don't want to lead anyone on a goose chase if there is a specific TnTLite build... If it is in the middle of the big thread then maybe you could put it somewhere more obvious maybe? I seem to remember post 195 from somewhere?

[Q] Howto mount NFS

I'm looking for NFS support on my SGT (Network file system, NOT the game...).
Tab has been rooted, running Paul's MoDaCo kernel & rom (amazing BTW), busybox and what not.
At home I'm running Ubuntu workstations and servers and know my way around linux.
However, I can't figure out how to mount my Tab to my NFS shares.
I've tried CIFS manager, ES filemanager and Mount manager, all without success. It seems to me I might be missing the correct modules. So the question is; is NFS supported in the first place? And if so, what am I overlooking?
(and could someone please post in the Modaco Kernel thread, as I don't have permission to post in dev-threads untill I spam at least 10 posts...)
[EDIT 2011-02-01]
Paul has indicated he might include NFS support in R4 of his kernel, no support in R3.

Hi
Editing post as I saw you are already on MoDaco's ROM.
Not sure about NFS but you mentioned Ubuntu..meaning you should have no trouble getting your samba server running.
With samba and MoDaCo custom Kernel you just need to pull down its "kernel modules.zip" It's a separate file containing the cifs.ko module.
Use CIFS manager (download from market) and specify where you extracted the module to (/sdcard/cifs or anywhere you want to place it).
Once cifs manager is able to load the cifs.ko module, you should be able to mount the shares

@bullyfrog Using the smb server and the cifs.ko modules is an alternative indeed, and for the time being a suitable workaround. Thank you for this tip. However, it's not what I was hoping on...
BTW NFS support will be included in next kernel, so hopefully by that time I've figured it out and will post as a Howto...

[KERNEL] corvusKernel |.32|CIFS|TUN|EXT4|SLAB|CFQ|WiFi|NTFS|HOST/SLAVE|PL2303|XPAD

Hi all.
I make a new kernel based in Buzz Vega, but with some changes.
1) All modules (but wifi) are now integrated into kernel, so no more insmod modules.
2) Added support for PL2303 and FDTI usb to serial chips (Usb Gps, usb-serial cable, etc.)
3) Added support for Xbox 360 PAD (wired or wireless with pc adaptor)
Notes:
1) To boot in host mode, press on, once you have black iluminated, release on button and press back until boot finished.
2) Usb Gps and Xbox pad are detected by kernel but not useable in android by now. I'm working on it.
3) To mount CIFS shares, you can use Mount Manager or Cifs Manager from market
4) To use NTFS (and possibly EXT4) you must mount manually. I'm working in do it automatically. Using ConnectBot:
Code:
$su
#busybox mount /dev/block/sda1 /mnt/usbdisk
And you get yout memory at /mnt/usbdisk and can access it with any file manager.
INSTALL:
This must be installed using CWM, and use this zip as update. MAKE ALLWAYS A NANDROID BACKUP BEFORE
If you was using Buzz Vega, can delete .ko files from /system/lib/modules, because they are not used (now integrated into kernel).
http://dl.dropbox.com/u/13580211/corvusKernel_01.zip
Thanks Buzz, Paul "Modaco", Koush, and all great helping people at #tegratab.
Corvus.
PS: If you prefer speak spanish with me, please PM.

Awesome work with the Xbox360 controller. What kernel module did you use to achieve that? Just getting in to kernel stuff with the Vega so please excuse if my question is a little basic.

You can search for Xpad in .config or advent_vega_defaultconfig.

Hey corvus,
I just wanted to say thanks! Your kernel is running great on my POV mobii and I don't experience the root- or bsod-problems I had with buzz-vega kernel. Also the cifs integration works fine.
greetings...

Great to see developers starting to work on the Advent.

Installed this kernel on my Advent Vega. It seems the device came to live. Performance is much better now. Suspending and resuming now works better. Wifi resuming works great. Very nice job with this kernel, very nice indeed

what adapter do you use? using xbox remote would be amazing

None by now... they are detected by kernel, but not used by android... working on it.
Corvus.

i thaught as much. good luck with that using an xbox remote on a ps1 emulator would rock!

hi! what about the kernel source + config?
like to add dvb-t and bluetooth hid (doesn't detect that my bt keyboard is a keyboard..)
and ive got some strange issues with the orientation sensor, seems like its shifted to the left so when i want to get into landscape mode i must rotate it much more to the right side (so i used the lock that i can work with that). No issue with CM7.
EDIT: ive got an xbox 360 wireless controller for windows (with the usb reciever), do i need to have some external apps or something to use this?

Sorry by the delay.
Sources and default config are here: https://github.com/BuzzBumbleBee/android_kernel_advent_vega/
For dvb-t you will need some kind of program to reproduce video...

No problem
There is an DVB project for Archos devices, maybe this is a start..

/lib/firmware/[KERNELVERSION]/ no luck

i think that you refer to wifi firmware...
I found this problem too...
You must edit wifi sources (/drivers/networking/wireless/ath/ath6k/.../ar6000.c, if i remember correclty). Search for firmware and change all paths to /system/lib/hw/wlan (if i remember correctly, search in this path for files).
you can recompile only wifi module, not need to recompile all kernel.
If you have any other problems with firmware, you need to change sources, because /lib/firmware is a bad place, because /lib is not created. Is better to point to /system/lib.

[Q] Q: Cifs.ko module for tf101 ICS kernel?

I just installed ICS and it works fine. I never expected it to work as well as it does, but now I can get down to griping about little things that I use that don't yet work
Normally I use CIFS (Common Internet File System, like Samba was before) to access shares on the net. This worked fine on HoneyComb because I built my own kernel modules.
For ICS, I think the source is not yet released for the kernel. I did see that there was a tun.ko and cifs.ko for ICS over in the transformer prime section of XDA, so I tried those out but it appears the tegra 3 kernel is too different for these to work. (although I think the version is the same).
If anyone has seen or has a working cifs.ko module I'd appreciate getting ahold of it (or especially the ICS kernel source code).
Thanks -

I don't know about cifs.ko as I don't use it, but I do use OpenVPN and found out that tun is part of ICS now, you no longer need a separate module.

I didn't have much success with tun and cifs for my purpose which was to wirelessly access the sd card of the phone/tablet vice versa until I used the Samba app fom the market. In combination with Ghost commander and after upgrading to ICS everything was intact. Not sure if this is helpful to you or not. Just throwin it out there.

Thanks both of you -
I realized that tun was there but thanks. As for cifs, I suppose the module isn't really needed except to use certain utils that rely on it, like root explorer.
I found a number of samba/cifs compatible file managers that're fine for me like ES explorer etc.
Those will be fine and I'll look forward to getting kernel source for ICS anyway.

I've just rooted my TF101 (ICS) so that I could get Junos pulse working with its ssl vpn. Doing a bit of reading I found I needed tun.ko (at least with 3.2). That automatic tun.ko installer from the market reports that tun.ko is installed (compiled into the kernel?)
I can see the tun0 created, with an IP address. But it doesn't work, not a single bit travels the tunnel interface.
I'm officially confused...

Still too few posts under this account name to be able to post links, but have you seen this thread in Dev?
xpad / cifs modules for stock kernel ICS v9.2.1.11

Thanks for that... that confirms tun.ko is built in, which doesn't help me find/fix my problem.
Will keep at it!
