[Q] btrfs

I was a winblows mobile user that always wanted to go to android and finally did recently.
From what little I could find about the subject, it looks like android kernels should support btrfs both on root/internal devices and sdcard. Is this correct?
Are there any ROMs (for Epic?) that are on btrfs?
If yes, is there a good repo / index of android ROMs for Galaxy S devices?
If not, can somebody please offer some guidance for a "kitchen" equivalent to roll your own. I've used desktop linux distros for 5 years but I'm an android newb.
I read the thread about lagfix but I'm not sure of any useful implications as far as this question...
Thanks!

Eclair runs 2.6.29, which is the first mainline Linux release to include btrfs. But btrfs isn't enabled in the stock Epic kernel config, not sure if it's enabled in others. That said, 2.6.29 is quite old in terms of supporting an experimental file system.

I don't think so, but what would be the advantage of it? btrfs primarilly targets scalable storage--"large" storage clusters with tens of spindles, at least. The limit of 1 GBish (I forget) internal storage and 32 GB SDHC storage wouldn't benefit much from it, except for transparent compresion and COW, maybe. But even then, ROMs are basically read-only.
I guess you could use btrfs on an SD card if you really wanted, but it would only be mountable by btrfs-capable hosts.

Thanks for the reply. I was thinking for both internal and external storage. See http://lwn.net/Articles/387196/ for why.

btrfs is optimized for flash storage, it provides data security, performance and compress ability. I think it is suitable for android. but it is not stabilize enough for business use. maybe next generation of android will support it

BTRFS - optimized - true, but ...
btrfs is still a beta filesystem, it's not recommended for the usage in productive enviroments. I tested it on my debian server and it's a very performant filesystem, but some stuff is still missing like fsck.btrfs.
although it's possible to compile your own kernel with btrfs support ; ) take a look at the cyanogemod wiki / compile your own kernel.

Hi Nyl, clearly you are very talented and you are making a tremendous contribuition to the XDA/TG01 community.
Now dont take this the wrong way but would it not be a good idea to pool your findings with the guys having problems getting Android to run on the TG01 as you seem to have overcome the stumbling blocks they have reached?
I know Linux is not the same as Android but in terms of getting radio, 3g working your work may go a long way to helping those guys out??

this build gonna be available for download as official kubuntu release, if i get it working and the other ubuntu version will be canceled as fact that kubuntu mobile is more finger friendly...

hi ^^
if i understand, you dont know username and pass
i found this for ubuntu hd2
user: 'htc-linux'
password: 'ubuntu'
Hope this can help

Nice project!

I forgot to state that this ain't related to HD2 Ubuntu this is a new project from scratch specially made for tg01
the problem is that i don't have any hardware keyboard to create new user and login

I know nothing of android, so sorry if this is useless, but..
I believe that the Kernel from the android project has USB support, so maybe you could connect a USB keyboard to the host cable and connect to the TG01.
I'm only thinking this because I've seen a photo of a device i can't remember running Ubuntu with a USB keyboard
I realise this may be useless if the host drivers are not there but don't know enough to go and find out.

well my problem is that i can't run qemu ARM on my linux/windows OS

h ttp://fedoraproject.org/wiki/Architectures/ARM/HowToQemu

Cant wait till it is ready! I love your ToshDroid ROM

nyl> Are you still continuing with this project?

I subscribe to this!
Great project. I hope you will manage to fix that wifi driver
Too bad that people who ported Android to htc hd2 don't want to share with us the secret of converting the wm wifi driver to a android/linux wifi driver...

This is like a revolution for testers
Applying that to Voluntas will make it easier to test and faster to update
No more Dropbox as i think
Waiting for Larieto to confirm this
Edit : tried to use it right away but the app that generate the device id is not available yet & it will be available on Samsung apps later
Maybe this will give Samsung more control over the whole process
Best Regards

Thank you mylove but there's country restriction...

You can find this App for your country via search... simple enter testkit.

After several tests we found out something really bad
This test kit have a 5 users limitation
So we can take just 5 testers for any app

Want to try Ubuntu Touch on your phone? We're almost there!

In the last weeks I blogged a couple of times about how we want to get Ubuntu out to more and more users in a much much easier way. It would be great if we could have gotten all images built in the data centre, but unfortunately do redistributability issues (some firmwares, blobs and proprietary kernel modules) not allow us to redistribute them easily. Another issue were some short-comings in our infrastructure, which have to some degree been fixed already.
Anyway... we wanted to make it easier and take sort of a short-cut, so the unstoppable Sergio Schvezov sat down and restructured phablet-tools to let us much more easily support community ports of Ubuntu Touch.
What does this mean?

Up until now, phablet-flash just supported these four devices: Galaxy Nexus, Nexus 4, Nexus 7 and Nexus 10. That was it.
After some discussions with port maintainers around the globe, we are quite happy to announce that we are now adding the following community ports to the mix: HTC Desire Z, Samsung Galaxy S2, Huawei Ascend P1. Now the family of phablet-flash‘able devices would look like this:
Once Sergio’s branch has landed, you will be able to just run
Code:
phablet-flash community --device u9200
to flash your device. (The above would be what you’d need to type in for a Huawei Ascend P1.) Until then you can just
Code:
bzr branch lp:~sergiusens/phablet-tools/flash_change
and run it from there.
More and more devices are on the way, and the process for telling phablet-flash about your port is actually quite easy.
You can help!
If you have any of the devices lists on our Touch Devices list, and you made a backup of things and you generally know your way around in terms of flashing, etc. Do the following:
Check if your port is registered already. If yes, great. If not, please talk to the port maintainers listed on the page linked from our devices list and follow the instructions for registering the port.
Code:
bzr branch lp:~sergiusens/phablet-tools/flash_change; cd flash_change; ./phablet-flash community --device <vendor>
(ie, i9100)
Give feedback on the ubuntu-phone mailing list.
Thanks a bunch in advance!

Quick update: now it's just
bzr branch lp: phablet-tools; cd phablet-tools
./phablet-flash community --device <vendor>

(Remove the space between "lp:" and "phablet-tools" - auto-smiley got me here.

If you run saucy and have phablet-tools installed, you can now just run:
Code:
phablet-flash community --device <vendor>
Great work, everyone.

Any word on when/how we'll be able to use CM10.2 to build the Android parts? I don't have much of an option for the new N7.

Fedora 23 Workstation on Lenovo Yoga Tablets

So a real fedora installation is working now on my Lenovo Yoga Tablet 2 Pro, this means real GPU rendering and everything. Some things aren't working at the moment so I can't release it yet , but I'm looking for someone that is good at bash shell scripting, and would maybe want to help out with creating the installer (the installer I created was just a quick hack). So if you're up for the job feel free to message me.

nice job!
a call for X-philes is in order

I'm interested in gnome working....pm coming...

Amazing!
Real GPU rendering!? Gnome!? Nice!
ps. Can the Steam games with it?

Definitely , the thing is that the touchscreen isn't working at the moment because of some driver issues, need to file a bug with the kernel but I'm not sure if to file it against the USB subsystem (Which doesn't seem to work), or if the drivers are just not compatible and need to be ported to the latest kernel. So there's some more work to do before making it usable.
And it will probably run faster than the android, since the kernel and its drivers will be compiled against the specific processor in these tablets, but for steam, that isn't created for handheld devices so the hardware might not be powerful enough, who knows.

Thank you
My goal is to run Indie Game (FTL, FEZ, ... ) and using Desktop os in Tablet

This is proving to be pretty difficult. There are basically 2 option for making this work.
a) running a kernel provided by lenovo (which is pretty bad and has old drivers for everything), I got this to build and work with the touchscreen, but it needs more hacking to not shut down automatically because of bad driver code
b) porting 2 drivers to the newest kernel (fsa9285 driver, and synaptics DSX)
Option b is most optimal, since we'd have good driver code running on the latest kernels, but hard if you don't know driver development (which I don't), but this is what I'm trying to do since it only involves a few files.

great job !

Excellent work ?
