Develop Bugs

[DEV] Kernel sources for Nexus S released :)

Everything starts here
http://twitter.com/#!/dnaltews/status/14849739858116608
- already pushing a mirror to github -
Funny thing is that several GalaxyS developers found this non secret at all repository about 2 months ago, but we didn't knew back then that Nexus S will exist, neither how to use these sources.
Now we do !
What does it tells for us Galaxy S developers:
- we can borrow some bugfixes from the 2.6.35 kernel version, for all the Galaxy S phones
- we can study how the Nexus S drives the 512MB OneNAND device, using YAFFS2
- some of the closed components on Galaxy S kernel may be free now in Nexus S.
EDIT:
Nexus S kernel built for GalaxyS.
Boot, give you a shell. Nothing more. Can be use to analyze things

I tweet a lot about sources analysis :

http://android.git.kernel.org/?p=kernel/samsung.git
So what does everyone make of this?
I'm on Windows atm, or I would diff to see the difference.
edit: Do they release the source for the rest of the ROM?

Now all we need is a dump from that phone

Do you think we might be able to see some of the Nexus S kernel, graphics, GPS improvements on Galaxy S soon?
Also, this doesn't provide the full ROM (i.e. Gingerbread source), just kernel/drivers right?
Only 2 more days until we can get a Nexus S dump though!

Nah man, we may have a dump in less than 12 hours time.

Waaaaaah nice. Like a chrismas gift.

Ext4 for /system and /data, but parts are hosted on the OneNAND in YAFFS2

Yup, Nexus S is EXT4.
Looking forward to a bright SGS future.

Sorry for beeing such a noob, but does this mean it might be possible to have a rom for SGS without the need for lagfixes for speed?

lagfix is nothing but a file format change from RFS to ext4. So long as Galaxy S defaults to RFS, we need to change it to ext4 and it will be "called" a lagfix.
PS; and in Nexus S it WONT be called a lagfix because it is the default.

Thx Santa Claus
We want have Galaxy S first device with Gingerbread..ops sorry second device

Please xda gods deliver us gingerbread....

Ext4 module

this is ext4 module binary for linux kernel 2.6.35.7 (DXLB1 stock firmware). i build to test my tools (compiler, etc.) and ability to load kernel module from stock kernel. if anyone needed, feels free to take it. working with loop device (not testing yet with real partition but it should be working) with following issue :
1. stock kernel not support "huge_file" feature witch is enable by default by mkfs.ext4. make sure to disable it
2. auto detect filesystem in mount command not working because wrong auto detect order. use"-t ext4" param
3. file size is big. not sure fit in initramfs (not investigate yet)
load module with insmod, jbd2.ko first and then ext4.ko.

vold.fstab is no longer used in 4.3. Instead, fstab.<device> is now unified. Check the contents of yours. Unfortunately, this means you'll have to unpack your boot.img, modify the ramdisk, repack and reflash.
Refer to http://source.android.com/devices/tech/storage/ although it doesn't provide nearly enough information in my opinion. I end up digging through sources for various devices.

You can see if any of the kernel zips are using the "anykernel" method and modify the script to suit.
If you can't find one, you can download one of the zips from http://forum.xda-developers.com/showthread.php?t=2181820 and figure out how to adapt the relevant ramdisk patching section (look in tmp/otgmod.sh) to suit. It basically dumps the current boot.img, breaks it apart, mods the ramdisk, makes a new boot.img, and then flashes it. Strip out all the irrelevant parts and change the partitions to suit.

Has anyone found a way to do this in 4.4 yet, specifically CM11? Switching with the build.prop isn't working for me.

I don't follow your phone, but nonetheless, build.prop mods shouldn't have worked in 4.3.
Further, starting in 4.4, the external sdcard is also run through fuse. See http://source.android.com/devices/tech/storage/config-example.html specifically the last section: Emulated primary, physical secondary (like Xoom)
From there, you can understand what needs to be switched. Again, this requires modifying the ramdisk.
I don't know if there's some sort of hack that'd allow you to change a global variable from a child. Perhaps, an init.d script would work at the parent level? If so, you may be able to switch around EXTERNAL_STORAGE and SECONDARY_STORAGE that way. The paths will remain unchanged, but proper android apps should respect the env vars.

Hi
on Kitkat, the mounting are set in the fstab files which are inside the boot.img file.
To edit them, you should unpack the img file, edit the files, then repack it in order to flash it.
The way to unpack them depends on the device manufacturer. For MTK devices, it is here : http://forum.xda-developers.com/showthread.php?t=1587411&page=29
I did it successfully on my Cube tablet in 4.4.
For others, you should find the tools on the web...

[Q] chroot Ubuntu on Nexus 7 (2013)

Not sure if anyone is interested or not but I have a chrooted Ubuntu 12.04 and Ubuntu 13.10 on my N7 running.
If anyone is interested I can post the steps and scripts I used, so you can do it yourself, and learn as you do it which is fun lol.
Most of the information is available via google searches however some things are not mentioned.
I have almost got LXDE running in the chroot without vnc, however not fully.
The problem I am having is when I startx or xinit /usr/bin/lxsession it displays a blank screen. When I kill the process, the LXDE background displays with a cursor. Not sure why it waits to display when I kill the process kind of weird.
Anyways thoughts, comments, constructive criticism.

photo of the adb screen launching startx img1.jpg
photo of the actual N7 screen img2.jpg

I guess there is a guide already from what I read.
No need for a guide unless someone wants to try making their own Ubuntu chroot. Then you will have the ability to make you own image size etc.
If anyone is interested or wants to do this post here and I will provide the steps.
And assist with scripts and what not.
By no means did I come up with this on my own, however many guides have scripts that don't work etc due to your version on android or device etc.

I'm using the guide in the General Section to use Kali PwnPad with my N7. I was using Backtrack with my 2012 and just bought a 2013 and very happy so far that everything works with Kali but with a better performance!
Wifi USB host was the main concern and it works great.
Nice job you have done too can you send me or share your chroot script please?

yes, do you need startup scripts or launch scripts for vnc and x
or just the chroot script to get into linux?

UPDATE
I made scripts which will allow the creation of the linux image right on the device itself.
It downloads approximately 200 megs for the packages, no more need to download huge image files...
Right now ubuntu works for sure testing others...

im pretty sure its something in the updater-script within the rom,you just have to change it from mounti ext4 to mounting to f2fs,someone in the dirtyv thread compared the commotio script and a slimkat one and made a slimkat f2fs,plus you have to use the kernel from the alpha commotio rom as well

How I changed paranoid (pa_maguro-4.4-BETA1-20140603) a f2fs compatible ROM.
1) Download latest dirty f2fs compatible kernel zip file. Extract the file "boot.img" to a temporary location
2) Download ROM zip file.
3) Open ROM zip file using 7-zip. Delete "boot.img" and replace with "boot.img" from the dirty kernel (saved in step#1)
4) Open ROM zip and browse to "\META-INF\com\google\android\". Extract "updater-script" to a temporary folder.
5) Open "updater-script" in a text editor. I use notepad++.
6) Replace string
"mount("ext4", "EMMC", "/dev/block/platform/omap/omap_hsmmc.0/by-name/system", "/system");"
by
"run_program("/sbin/busybox", "mount", "/system");"
Again, replace string
"format("ext4", "EMMC", "/dev/block/platform/omap/omap_hsmmc.0/by-name/system", "0", "/system");"
by
"run_program("/sbin/mkfs.f2fs", "/dev/block/platform/omap/omap_hsmmc.0/by-name/system");"
7) If you need to mount data partition add string
"run_program("/sbin/busybox", "mount", "/data");"
after strings
"run_program("/sbin/mkfs.f2fs", "/dev/block/platform/omap/omap_hsmmc.0/by-name/system");"
"run_program("/sbin/busybox", "mount", "/system");"
8) Add string
"symlink("../bin/fsck.f2fs", "/system/bin/dump.f2fs");"
after
"package_extract_dir("system", "/system");"
also add string
"symlink("mount.exfat", "/system/bin/fsck.exfat",
"/system/bin/mkfs.exfat");"
after
"symlink("mksh", "/system/bin/sh");"
9) If you loaded data partition in step 7 you'll need to unmount it at the end by adding string
"unmount("/data");"
10) Replace original updater script the edited one in the ROM zip.
11) Done.
12) Seriously. It's done. Go test it out.
Basically, all(hopefully) this does is, it make sure that ROM's updater script formats/mounts partitions are f2fs, rather than ext4.
Again, I'm not a developer and have just a little working knowledge of what these commands might do. Use this at your own risk.
I've attached original and updated scripts that I've used. You can use compare (ctrlD) feature in notepad++ and see difference between them.
Hope this helps. All the best. :good:
To all the developers and smart people out here, please feel free to suggest changes, or let me know when there's a more comprehensive guide out there, so I can remove this and link to the improved post.
P.S. This might look complicated, but just takes about 5 minutes, not including download time.

I did exactly the same, however for slim there was no need to add some lines.
Simply, from what I saw, replace every line that has mount or format ext4 with the appropriate line for F2FS:
mount("ext4", "EMMC", "/dev/block/platform/omap/omap_hsmmc.0/by-name/system", "/ANYPARTITION");​
get replaced by
run_program("/sbin/busybox", "mount", "/ANYPARTITION");​
and
format("ext4", "EMMC", "/dev/block/platform/omap/omap_hsmmc.0/by-name/system", "0", "/ANYPARTITION");​
get replaced by
run_program("/sbin/mkfs.f2fs", "/dev/block/platform/omap/omap_hsmmc.0/by-name/ANYPARTITION");​
obviously:
1.change ANYPARTITION following the partition wrote in your updater script
2. REPLACE ONLY WHAT IS NECESSARY: I think you should not add MORE format partition lines than the one present before. Just replace what you have. If you followed the steps explained by AOSP inside the DIrtyV thread, you should have already all the partition F2FS formatted.​
A useful thing to do if you have doubts (is what I've done) is to search if the rom you want to convert already has a F2FS version on another device and compare the scripts (without caring about lines that are different because of the different device). For example, I compared Grouper's F2FS slimkat to maguro one, and thanks to this I've understood that mount/format partitions thing.

^^ Lot better.
