Hi,
I'm still try to bypass the MMU protection.
I have fixe a lot of bug, like memory misalignment, bad adresses allocation, dtb correction, etc...
Last sources and binaries here :
kexec-tools V11.zip : http://forum.xda-developers.com/attachment.php?attachmentid=2902912&stc=1&d=1408401794
kexec-tools binaries V11.zip : http://forum.xda-developers.com/attachment.php?attachmentid=2902913&stc=1&d=1408401794
Sorry, i have always 13 sec reboot after new kernel boot.
"cpu_proc_fin" use a "mcr p15" to init cache and proc that cause freeze.
I try to find solution for that.

Hi,
My sources are horrible... but i give something new.
This kexec is for stock kernel only (tested on .757). I thinks theses sources work on other kernel too.
In "kexec-tools V10.zip", you have all my sources. It's highly recommended to mod them to have something OK.
In "kexec binaries.zip", you have binaries to install
=> "kexec_load.ko" and "procfs_rw.ko" must be placed in "/system/lib/modules" folder with "chmod 777"
=> "kexec" must be placed in /system/bin" folder with "chmod 777"
=> cd /system/lib/modules
=> insmod kexec_load.ko
For sources :
Mod and adapt all you want, it's free.
You have 2 scripts in Zip : "./compil-kexec" in "kexec-tools" folder to rebuild and send in device directly (install Adbtcp on device and send by tcp with : adb connect xxx.xxx.xxx.xxx) = work perfectly with me.
"scriptZ1" is for compil stock kernel or another kernel (doomlord kernel for eg)
You must rename "custom_final_files" folder after compil to "final_file" manually ; You can have guest kernel in "custom_final_files" and stock kernel in "final_files" for "kexec-tools" path ... Don't mix a guest and host kernel please ^^
I am tired... i let you test and say if it's ok for you...
Thank a lot to munjeni for his help.

Hi,
For few days now, i haven't no more kernel panic with my kexec.
I have fixed few stuffs into sources, and add a lot.
These adds are, to include a "dt.img" image file into kexec load process.
This image file is a "device_tree" image to match hardware to software.
So, i assume to don't include atags into boot process, but pass bootloader informations by this DT.
I have programmed a little scan memory to found dynamicly all magic tags, because i found 3 device_tree into memory (magic is "0xd00dfeed").
These 2 device_tree are echo from first and nice structure.
The boot process need to have informations from this DT, and need all informations to initialize hardware (no HDW initialisation by the kernel)
I must first fix issues ; Regroup zImage and dt.img into memory to load a solid bloc to kexec_load module to boot into, and second, fix an offset i can't explain, 0x800 in memory causing misalignment memory
Keep tuned..

Hi everybody,
My kexec-tools work for Sony Xperia Z1 stock kernel "3.4.0-perf"
This tools can work on all locked bootloader for all locked device, not only Sony or Z1 models.
This kexec-tools add a kexec_load kernel module (LKM) and use a driver to grant a communication between "kexec" user program and kexec_load.ko module
what is for ?
"kexec" user program load in memory a custom kernel in zImage format, but can load ".tar" image too
This user tool load ramdisk in memory if necessary
This tool is for this purpose only, and don't keep in memory the custom kernel at device reboot.
It is a "user" program, not a "kernel" extension... So, to really do the magic, we need the host kernel (stock sony locked kernel) have a kexec_load capability to reboot in a new gest kernel (custom kernel).
Infortuntly, stock kernel don't have kexec_load capability.
Sony have compiled his stock kernel without this option, and "standard" kexec-tools "need" this option to work.
To see all system call capability of kernel, you can run theses command :
Code:
echo 0 > /proc/sys/kernel/dmesg_restrict
echo 0 > /proc/sys/kernel/kptr_restrict
cat /proc/kallsyms
Do all grep you want here.
The "echo 0" "restrict" is here to unmask logical adresses to "system calls"
Like you can see, "__NR_kexec_load" capability isn't here.
To add kexec_load capability in stock locked kernel, we need to add manualy a kernel module wich add this function into the kernel.
Why ? Because the way to keep in memory a custom kernel need to know a lot of parameters, and keep a specific memory range alive at reboot.
Only kernel can do this.
All user program will be terminated at reboot.
"Standard" kexec_load.ko module use a method to implement the "__NR_kexec_load" function in system call table.
Since 2.6.0 kernel, linux for security reason, have locked in memory the "system_call_table" ; No more add or modification is authorized.
If kexec tool try to add a value, "kexec_load" for us, we causes a kernel panic, and reboot device.
For this reason, i have modify kexec user program and kexec_load module to implement a driver to talk to each other.
this driver replace syscall method, and we no more need to use a system call table.
For this reason, this tool is now compatible with modern kernel like our "3.4.0"
For this reason, this tool must work for other device (Xperia X, P, S, etc...) and another brand
For this reason, if kernel is locked, we can bootstrap to run a new kernel.
Installation
First, you can compil your own kexec tool
Here, sources : http://forum.xda-developers.com/attachment.php?attachmentid=2397299&stc=1&d=1384689174
And here, the binaries : http://forum.xda-developers.com/attachment.php?attachmentid=2397305&stc=1&d=1384689406
(it's not a cwm zip, i have no time to create an installer for now ; use "./compil-kexec" if you want an automatic install)
Install *.ko in /system/lib/modules
Install kexec and kdump in /system/bin
Grant with "chmod 777"
Unzip in kexec-tools folder
Install a toolchain (sudo apt-get install gcc-arm-linux-gnueabi)
launch => ./compil-kexec
what's all
This script can do everythinks for you
- Compilation of tools
- Compilation of modules
- installation in device
This script can compil for every brand you have.
Except you must remove or adapt the patch (see below why)
Patch ??
This patch is because a module must be compiled in the same time the kernel himself.
For this reason a "vermagic", an identifier, is used by system to block every module not compil with kernel
Some custom kernel bypass this to authorize every modules.
But for stock kernel, it is not allowed.
You can easely strapp this by busybox.
"busybox modprobe" for help
"-f" to force load without vermagic
To see this vermagic :
Code:
# uname -r
This "uname -r" must be the same that
Code:
# strings kexec_load.ko | grep vermagic
vermagic=3.4.0-perf-g66807d4-02450-g9a218f1 SMP preempt mod_unload modversions ARMv7
If you want use automaticaly this vermagic, you can modify into the custom kernel this file :
Code:
"include/config/kernel.release" and add :
"3.4.0-perf-g66807d4-02450-g9a218f1"
This file will be use at module compil to match the vermagic.
Infortunatly, it is not enought. :silly:
The infamous "no symbol version for module_layout"
When a module compil is created, it use symbols link to system call function, translate by adresses
Theses symbols are not at same physical adresses in stock kernel and modules (compiled from DooMLoRD kernel).
So, theses adresses must be convert into modules itself to match with stock symbols adress.
A patch is needed.
If you use my script, modules are automatically patched.
Here patches :
Code:
sed -i 's/\x32\x76\x86\x29/\x72\xFF\x5E\x20/' procfs_rw.ko
sed -i 's/\x32\x76\x86\x29/\x72\xFF\x5E\x20/' kexec_load.ko

sed -i 's/\xFD\x23\xD0\xFB/\xE3\xE3\x68\x52/' kexec_load.ko
You can use hexedit or hexdump to see these adresses :
Code:
hexdump kexec_load.ko | grep ff72
0003d50 b0b0 80ac ff72 205e 6f6d 7564 656c 6c5f
how does it work ?
# kexec --help
For kexec help... nothing more to say.
# lsmod
List loaded modules... You must see
kexec_load 31369 0 - Live 0x00000000 (O)
# rmmod kexec_load.ko
Remove kexec_load module from memory.
# grep kexec /proc/device
To see installed driver.
You must see :
100 kexec_driver
First number is "major" number to identify your driver in system.
# mknod /dev/kexec_driver c 100 0
Install driver.
Major number (here 100), is important for module.
This Major must be the same between module and driver.
By default, 100 is used.
# insmod kexec_load.ko
To install "LKM", kexec_load kernel module.
If another Major is needed, you can use "insmod kexec_load.ko 101" for Major 101
You can use "modprob" if you want, but you must configure the module folder.
How kexec and module exchange informations ?
By the driver.
Normal output for a kernel module is to write in "dmsg" file.
To see kernel output, launch this command :
Code:
# dmesg
To see last kernel log, see in :
Code:
# cat /proc/last_kmsg
For kexec module, this normal way still exist, and give a lot of informations, but to speak with, you must use the driver.
/dev/kexec_driver
You can yourself test communication:
Code:
# cat /dev/kexec_driver
You can send kernel by this communication channel.
Type following commands for help
=> echo help >/dev/kexec_driver
=> dmesg | grep Kexec
Code:
# echo help >/dev/kexec_driver
# cat /dev/kexec_driver
Last command : 'help'
Please type following command :
=> dmesg|grep Kexec
Every command send into driver is receive by kexec_load.ko module and running into the kernel.
The answer can by read thru the driver
Here, you can see that normal way to see messages is allway dmesg.
Code:
# dmesg|grep Kexec
<4>[15050.521628] Kexec: Starting kexec_module...
<6>[15050.521656] Kexec: kexec_driver_contener allocation

I have add a lot of informations to help to configure kexec.
rdtags, atags ??
Not sure for this part of kernel.
"atags" is the most used method to bootloader to parse commands and informations to kernel at boot.
"atags" is a form of structure in memory to organise informations.
At boot, a address chain is created and can be compulse in /proc/atags file.
This file is read only system.
"rdtags" is another way to bootloader to parse information to kernel.
"rdtags" is not stocked in "/proc"
But, as i see, stock kernel can use "atags" from bootloader.
kexec can substitute bootloader function to create fromscratch a atags chain, and parse to new kernel.
I have change this part to stock atags in "/data/atags", and reuse or change if need.
If this don't work, i must create a rdtags chain to replace atags ; It's not a hard work.
Status
For the moment, kexec tools works.
=> Phase one OK.
I can start Phase Two : new kernel patch.
If you want to help me...
Actually, load a custom kernel and boot into with kexec tools work.
But at boot into, a kernel panic occurs.
It seems, a part of kexec patch is missing in custom kernel.
Hi new thread created for kernel kexec development.
Status: not working: wrong values for mem defines under the kernel is giving segmentation fault as its attempting to write to memory areas that are currently being used byyyyy the system
Instructions:
Make kernel compatible?:
1. Download kernel diff patch from below

Devdb?
Pm me i dont know what Devdb is lol
Recieved segmentation fault with delewers calculated mem values too
We need to write to memory where we have write access to, maybe lockedbootloader is not allowing us to write? Orrr we are just writing to wrong area of memory
If kexec works on the Z1, can it be ported over to Xperia Z/ZL/T/Ultra? I believe they don't all share the same processor.

Yes it wont matter much, since its not s800 it should be easier for you guys , take the kexec-tool use that, implement the patch write to the correct mem addresses which is free, it should boot if you guys have issues let me know,
I need to calculate the correct addresses.
Ive noticed s800 uses a dt.img, might need to modify kexec-tool to support dt.img, not sure what dt.img does yet, only know it holds values

the dt.img is needed by the kernel to boot, so I guess we need to load that too in kexec.

krabappel2548, i have compil your kernel by my script (fromscratch)
My script (instruction in "DoomLord Build kernel thread" : scriptZ1 http://forum.xda-developers.com/attachment.php?attachmentid=2346163&d=1382568778
(for thoses who want to help us...)
You have a little mod to do here (bad compil) :
In "sound/soc/msm/qdsp6v2/rtac.c"
you must change
#include <q6voice.h>
by
#include "q6voice.h"
btw : no more ideas to load kexec for the moment ...

Now need to find a free memory area thatll allow us to write and hopefully the mmu/pmu on locked bootloader wont cancel it

I know I shouldn't disturb, but i must ask: if You achieve Your goal, would it be possible to port it to devices like Xperia P, S, T, U and other NXT? It would be great, many ppl are ready to give a prize for it. Thanks in advance, good luck and sorry again.

These devices are not 2013 devices, they arent s800 socs, so they are much easier to do, simply take the kexec-tools from op, implement the patch in your kernel, write the correct memory values for your specific device and execute in terminal via the command in op, minmem depends on your device too, good luck
I think some1 tried it already, but it works only for unlocked devices... Anyway, thanks for help.

INTRODUCTION
I wanted to port f2fs for our device since it gives a nice performance boost. After few months of learning how to develop and program his own custom kernel here is my first personal release.
This is an open devDB xda project. Feel free to fill in bugs reports, feature(s) requests and reviews.
To those who don't know what is f2fs
F2FS (Flash-Friendly File System) is a flash file system created by Jaegeuk Kim (Hangul: 김재극) at Samsung for the Linux operating system kernel.[2]
The motive for F2FS was to build a file system that from the start takes into account the characteristics of NAND flash memory-based storage devices (such as solid-state disks, eMMC, and SD cards), which are widely used in computer systems ranging from mobile devices to servers.

Optipops features :
Kernel's features :
Compiled with linaro 4.7.4 with optimized flags : O3, etc.
Linux 3.4.67: synced with cyanogen 's manta kernel git, google's common branch, some parts of the kernel updated to 3.4.108, and many fixes from CAF,linaro, blabla.
Governors : interactive, intelliactive,intellimm,conservative, ktoonservative , performance, userspace, nigtmahre(on request)(ask for some others if you prefer them over the one I provide)
I/O schedulers : noop, cfq, deadline, bfq(tweaked for nand devices),fiops,zen,sio
f2fs updated from upstream git(08 september 2015)
UV and OC both for the GPU AND CPU supported
Control for the gpu table thresholds
touchboost driver for cpu and gpu in replacement of crappy powerHAL touch interface ( thx @franciscofranco to have adapted qcom code to ageneric one)
arm optimized crypto algorithms.(for the ones that want to crypt their data)
f2fs crypto support
kernel neon support
kernel side touch boost driver
double tap to wake
AnyKernel2 Solution: Allow users to install the kernel on different distribution. It also detects the filesystem of your partitions to produce a correct fstab. ( f2fs is supported on any partition BUT system )
and many more patches(see my github!)
installation instructions :
Wipe Data Cache System
Flash The kernel
If issues are met, delete the
Code:
/sdcard/Android/data
folder.

How To Migrate one partition from ext4 to f2fs(vice-versa):INSTRUCTIONS FOR TWRP 2.8.x.y
GunnerOnASpooky said:
1. Backup everything from your internal storage to your PC or what ever, if you are migrating /data partition,since the entire internal storage is going to get wiped out with format!!!!!!!!!!
2. Download the recovery from my gdrive
3. Flash the recovery from the bootloader (fastboot flash recovery XX.img)
4. Reboot into the newly flashed recovery
5. Choose wipe, advanced, then select the partition you want to change its filesystems
6. Choose the change file system option on the right
7. Select change file system again
8. Select f2fs(or ext4)
9. Repeat for all you wish to convert (I did system!/data/cache but /system partition should be working if you rom package flash extracts instead of flashing an image)

frandom: A fast random number generator
block:
block:bfq:adjusted tunnables for nand devices
block:bfq v7r7 v7r7: . BUGFIX: Prevent the OOM queue from being involved in the queue cooperation mechanism. In fact, since the requests temporarily redirected to the OOM queue could be redirected again to dedicated queues at any time, the state needed to correctly handle merging with the OOM queue would be quite complex and expensive to maintain. Besides, in such a critical condition as an out of memory, the benefits of queue merging may be little relevant, or even negligible. . IMPROVEMENT: Let the OOM queue be initialized only once. Previously, the OOM queue was reinitialized, at each request enqueue, with the parameters related to the process that issued that request. Depending on the parameters of the processes doing I/O, this could easily cause the OOM queue to be moved continuously across service trees, or even across groups. It also caused the parameters of the OOM queue to be continuously reset in any case. . CODE IMPROVEMENT. Performed some minor code cleanups, and added some BUG_ON()s that, if the weight of an entity becomes inconsistent, should better help understand why.

Thanks a lot for your work.
I'll try it with CM asap.
For more download convenience, can you upload an all-in-one zip with recovery and the 2 kernel somewhere else than github, it could be difficult to download from there. Thanks again.
yeah, i ll put it on mediafire.

Awesome work man!
F2FS fully working on System/Data/Cache with SlimKat 5.8 weekly 4.4.3 and your F2FSall Ktoonsez kernel...
Nexus 10 is flying now!
EDIT: I'm getting a bunch of freeze-ups which result into reboots, is this happenng to anyone else?
Steps i took:
fastboot flashed kt-twrp
changed settings (including /system)
wiped what needed to be wiped
replaced Rom script( SlimKat weekly build 4.4.3)
installed rom, correct kernel, and gapps
Any advice would be appreciated!
I have some pb too. It's quite impossible for me to copy something from my usb stick to the internal memory. It freezes almost every time.
No problem in ext4 with same ROM.
Only problems I encountered were freezes/reboots for the very first hours of use, been so far in full f2fs with cyanogen M7 no probs here.
However, did you try with only cache+data partition?
Yep, I was on cm nightlies and data/cache only.
Now I'm trying omni, I will try with this ROM
Could you paste the content of the fstab please?

About the fstab: What updates the fstype for the partitions we choose to convert to F2FS? Is TWRP 'smart' enough to write the proper /fstab.manta? I thought the boot.img in the ROM zip contained this file?
Really excited to switch to F2FS, I've been running it on my Arch boxes for a while now. Anyone worked on an auto updater for the updater-script? I'm on OmniROM and flash daily so it would be nice to not have to hand edit and re-pack the zip every day. I'd look into doing it but I'm not super confident I'd go about it the proper way.

For now, TWRP can detect when you are wiping your partition what tools it would has to use. I.e : if you choose to wipe data partition, system, etc.
And use the correct tool accordingly. But official version do not mount yet however f2fs partition.
The fstab is in the ramdisk, so contained yep in the boot.img. But there are few mount options, some may need to be activated in case of unstability

Thank you for your reply. Perhaps the best thing is to create a flashable zip to be run after ROM flash to install fstab.manta?
Also, FWIW, here's some sed commands to update your updater-script per the instructions in the OP:
Code:
sed -i 's/^mount("ext4".*\/system*/run_program\("\/sbin\/busybox", "mount", "\/system"); /' updater-script
sed -i 's/^format("ext4".*\/system*/run_program("\/sbin\/mkfs.f2fs", "\/dev\/block\/platform\/dw_mmc.0\/by-name\/system"); /' updater-script

Hello I just added some executable java program that convert a rom script to be f2fs compatible.
Also, having less issues with lastest kernel build but I tried it on new roms. ROMs fully working so far and stable : liquidSmooth 3.1 & slimkat 4.9.
Before I was using CM11 M7 it was working but was encoutering some freezes/reboot- especially at the beginning - but then it was ok. I can not tell if this is still happening with cm rom.
I haven't test the pc program on windows if anyone could say it does work, thx!
EDIT : thank to @dust40; he told me the tool was working on Windows as well! Should work on mac too then i guess.
Well I successfully converted /data and cache to F2FS. I made the effort way more work than it had to be by preserving my data. WAY more work. Booted in recovery mode I tar'ed up /data to a exfat formatted usb-otg drive then ran the conversion. Ran into 'value too large for defined data type' errors from tar when extracting. I ended up extracting the tarball onto my workstation, deleting the file it crapped out on, tar'ing it all back up to the usb drive and re-running the extraction. Had to repeat this procedure a good dozen times and I ended up with messed up permissions on all my data. I don't suggest anyone try this because it would have taken much less time to just set up a fresh installation, but if you do here's some good commands to fix up permissions (TWRP's fix permissions command doesn't fix what I messed up). I found these commands at http://forum.xda-developers.com/showthread.php?t=2222297 but had to adjust them a little bit. The chown command has to be run when booted to android, the chmod commands can be run from either recovery or android. Reboot immediately after running. Best to run through adb shell than in an app on the tablet.
Code:
find /data/media/ -exec chown 1023,1023 {} \;
find /data/media/ -type d -exec chmod 775 {} \;
find /data/media/ -type f -exec chmod 664 {} \;
@Khaon, can you ask ktoonsez to compile 4.4.4 versions of the kernels? Latest OmniROM update for manta is 4.4.4 but will not boot with this kernel. And obviously I cannot run any other kernel as none others support F2FS. Thanks in advance! And thanks for putting this thread together. Without your good instructions I probably wouldn't have had the guts to convert this early.
One last thing, I can report that OmniROM works perfectly with /data and cache formatted as F2FS (once permissions are set right!). And since I preserved my data I have an apples to apples comparison of performance and it is noticeably faster and smoother!
kt-recovery stuck at splash screen
Hi,
I had originally posted this in ktmanta thread:
I have been running F2FS on cache+data for past 2 weeks and it works very well (still some strange system freezes, i will need to investigate further on that).
However, now, when i boot to recovery, screen stays stuck at splash screen showing "f2fs enabled by Ktoonsez..", and does not go anywhere else. i can still flash using adb, but clearly, it's less than convenient, and using twrp 2.7.10 is not an option, as it can't mount f2fs sdcard properly anyways.
with adb shell, i can see that all is mounted properly, f2fs or not, but obviously, it's less than ideal... i have attached /cache/recovery/log file .
Note: i connect usb cable 2 to 3 mn after waiting for splash screen to go away, and i pulled recovery log at that moment. this was also the only way to get out of this stuck mode, via 'adb reboot' command.
i also tried to re-flash recovery via fastboot, but that made no difference.
any help appreciated !
@ericp2 @b1g.p0ppa
Can you just try this recovery and tell me if you are running any issue? This is just last official twrp 2.7.1.0.
Just formated and installed a new ROM, ran into no issue, guess should be the same for you .

Glad you like the kernel running this, if I understood correctly, you wanted to back up the internal storage( so /data/media/0) and your apk folder to an exfat usb drive you mounted with otg? If the fs of this one was exfat that is probably the cause of your issues, I am not even sure our tablet nativly supports exfat( isn't a samsung fs that allows 32GB ++ partition size?). Lastest Omni kernel is booting I assume?

Issue fixed. this version of TWRP starts correctly, and f2fs formatted sdcard can be listed, so i can again flash CM updates.

Since fire phone doesn't have a bootloader unlock at the moment. There is no point in building a custom kernel. But By building a kernel we can build kernel modules which work on the stock kernel. And yes you can load unsigned kernel modules without a problem since fire phone doesn't use tz apps to verify kernel modules like Samsung does.
Setup
Source
Download the fire phone sources for firmware 4.6.1 from here. And extract the platfrom.tar inside the archive to somewhere(KERNEL_DIR).
toolchain
You can use the android ndk from google, But it requires some setup. I'm using linaro toolchain from here. You can use compiler version 4.7, 4.8 or 4.9. Kernel I'm using (Firmware 4.6.3 - Linux 3.4-perf-g280c96c) is built with gcc-4.7. But I'm using this gcc-4.9. Download it, extract is somewhere(TOOLCHAIN_DIR) and add the $TOOLCHAIN_DIR/bin to your PATH. Theoretically you would be able to build the kernel on windows using Cygwin or MSYS tools but using Linux is better.
config
Connect your phone trough adb and run
Code:
adb pull /proc/config.gz
zcat config.gz > $KERNEL_DIR/kernel/qcom/3.4/.config
With this config you will run into some problems because of a missing "trapz_generated_kernel.h". I don't know if this is an auto generated file when they build android as a whole or amazon removed this explicitly(can they do that without violating GPL?). Anyway It looks trapz is some low level kernel debugging function(comment here if you know more about it). We can safely disable it. Open $KERNEL_DIR/kernel/qcom/3.4/.config in a text editor and change the lines
Code:
CONFIG_TRAPZ=y
CONFIG_TRAPZ_TP=y
CONFIG_TRAPZ_TRIGGER=y
CONFIG_HAVOK=y
to
Code:
#CONFIG_TRAPZ=y
#CONFIG_TRAPZ_TP=y
#CONFIG_TRAPZ_TRIGGER=y
#CONFIG_HAVOK=y
building
Now edit the $KERNEL_DIR/kernel/qcom/3.4/Makefile and add this changes
Code:
EXTRAVERSION = -perf-g280c96c
This is at the top of the makefile. If we don't add this, vermagic for the modules will differ from stock kernel and they won't load.
ARCH=arm
CROSS_COMPILE=arm-linux-gnueabihf-
Click to expand...
Click to collapse
Here arm-linux-gnueabihf- is my cross compiler frefix. Look in $TOOLCHAIN_DIR/bin/ to find it.
Now cd into $KERNEL_DIR/kernel/qcom/3.4/ and do
Code:
make
The build will fail a few times complaining about missing headers. Most of the time it's just
Code:
#include <myheader.h>
instead of
Code:
#include "myheader.h"
Edit the source file where the build fails and change <>s to ""s. (maybe android ndk ignores the difference and include the headers anyway)
After kernel compiles, we are good to go. We can use this kernel sources to build kernel modules for stock kernel.
Kernel modules
To build the kernel modules, we basically need two things. An approximate kernel source and the Module.symvers file from the original kernel. We can get the Module.symvers file by building the complete kernel as explained above or Just extract it from our stock kernel.
To extract the Module.symvers from the stock kernel, extract the boot.img file from firmware update image. Get mkbootimg tools from here compile it and run
Code:
unmkbootimg --kernel zImage ---ramdisk ramdisk.cpio.gz -i boot.img
After you get the zImage. Download extract-symvers script from here and run
Code:
python2 extract-symvers.py -B 0xc0008000 zImage > Module.symvers
place this file in $KERNEL_DIR/kernel/qcom/3.4/ (You still have to do the changes mentioned above in kernel config and building section run make in the $KERNEL_DIR/kernel/qcom/3.4 and intrupt it after few seconds)
Now you can build loadable modules against this source. Here is a hello world kernel module.
Code:
//hello.c
#include<linux/module.h>
#include<linux/kernel.h>
#include<linux/init.h>
static int __init hello_start(void)
{
printk("hello to the world from module");
return 0;
}
static void __exit hello_end(void)
{
printk("heloo exit");
}
module_init(hello_start);
module_exit(hello_end);
Code:
#Makefile
KERNEL_DIR=<your kernel dir>/kernel/qcom/3.4
obj-m := hello.o
PWD := $(shell pwd)
default:
$(MAKE) ARCH=arm CROSS_COMPILE=armeb-linux-gnueabi- -C $(KERNEL_DIR) SUBDIRS=$(PWD) modules
Put this files in a folder and run make in it. Change the paths and cross compiler prefix according to your setup. and run make.
After the build push the hello.ko to the phone.
Code:
adb push hello.ko /sdcard/
adb shell
su
cd sdcard
insmod hello.ko
run dmesg and you'll see the message.
I'm currently trying to build kexec module from hashcode's sources and USB OTG modules.
I'm attaching a few thing helped me do this.
since they have released this version of the fire os they have to provide the source code
see
http://www.gnu.org/licenses/gpl-faq.html#GPLRequireSourcePostedPublic
you have just shown that the source code they releases for the kernel does not match the one used to build the kernel. This means it is a clear violation of the gpl and amazon is in breach and can be sued.
on another note.
are the drivers for the nfc and camera compiled as a module or into the kernel?
They have yet to provide 4.6.3 and 4.6.4 kernel sources too.
I don't know exactly but in order for NFC and camera to work drivers are required and they are in fact compiled into the kernel.
The problem we currently have with NFC and camera is proprietary hal (hardware abstraction libraries) They are a part of Android and does not subject to GPL. Amazon changed the original android way how hal works and didn't release the sources!
by looking at the kernel drivers maybe we would be able to implement hal from scratch. But I don't see that intense dev support for fire phone. If you are up for it camera sources are at $KERNEL_DIR/kernel/qcom/3.4/drivers/media/platform/msm/camera_v2/
Major MAJOR respect for all of you making the Fire Phone even better!

Could someone please provide the config extracted from /proc/config.gz?
I can't find this on CM11 rom for some reason.
Building the kernel now.
Some bugs are in the code and -Wall and gcc-wrapper.py escalate the warnings.
I wonder if those errors are there on purpose XD
helloworld.ko loaded successfully
I was able to execute kexec without anything. Just the binary.
Will keep you posted - this hacking might take a while to figure it all out.
I already have 3.4 kernel from the amazon sources.
I have the kexec userland program.
What is left is a loadable kexec kernel module (if that is possible at all).

Where are you getting your kexec module sources from? BTW try using the original amazon kernal binary the phone is shipped with (we are sure it works). Don't use the custom kernel for the kexec tests (We don't know the custom kernel actually works)

Here is the thread I used as a starting point.
I will put up my "fork" on github after I get permission to do that
The userland part build like a charm once I took the compiler you recommended.
The kernel-module was tricky because the whole thing is modded like hell.
To be able to load I had to comment out some hard coded addresses and the calls to unresolvable symbols.
removed
Okay the kernel gets loaded.
But
kexec -e shuts off the device.
strace doesn't help.
On the plus side:
Devices are shutdown
Look promising
I need a way to tail dmesg ...
Okay a lot of digging around and I found out that the reboot syscall doesn't work properly..
It doesn't look like it hits the kexec_module it looks more like it hits the actualy sys_reboot
Okay reboot syscall hits my reboot-hook.
But the softreboot doesn't work now.
Okay there is some kind of watchdog runnig which doesn't like my kexec.
I need to kill it - that should happen tomorrow.

Try changing GFP_KERNEL to GFP_ATOMIC. Other than that, I have another suggestion. Try to get the kernel to run in a single core mode before running kexec code. This might simplify things. I don't know how to do this though.

Testing your new kernel:
Download both attachments (KernelSwapper and BootimgRestore).
Append headers from stock kernel to zImage (which can be found at ./out/target/product/huawei82_cwet_kk/obj/KERNEL_OBJ/arch/arm/boot/zImage)
In KernelSwapper update 'kernel' with your own generated zImage rename it to 'kernel' and replace it inside zip.
In BootimgRestore replace 'boot.img' with your current ROM's boot.img in case that something goes wrong (e.g.: Phone not booting).
Copy the two new zips into phone's memory (or SD card) and flash KernelSwapper.

Yes, I'm sure that the kernel has multiple bugs. The phone may feel laggish because there is enabled low-level kernel debugging over UART.

Nope, it's ROM bug not a kernel bug plus I have released only development preview version which has enabled many debugging options and it may be quite buggy.
Thanks, but can this process led to a suitable kernel for CM13?

Aim of this project is to make stock kernel sources stable for KitKat ROMs (It is originally for KK) but somebody else may patch them for CM 13. I am not working on this nor I'll do.
Will you be adding extra CPU governors and IO schedulers along with kernel level wakeups for double tap waking?
I was wondering who else is developing kernel 3.10.XX for this device ?

Actually, nobody is working on 3.10.X kernel. And I'm rather focusing on LineageOS for now.

This should include most configs
Code:
/* Mediatek common */
./mediatek/config/common/autoconfig/kconfig/AEE
./mediatek/config/common/autoconfig/kconfig/USER
./mediatek/config/common/ProjectConfig.mk
/* MT6582 common */
./mediatek/config/mt6582/autoconfig/kconfig/platform
./mediatek/config/mt6582/ProjectConfig.mk
/* h30u10 device specific */
./mediatek/config/huawei82_cwet_kk/autoconfig/kconfig/project
./mediatek/config/huawei82_cwet_kk/ProjectConfig.mk

Replace Device Name with the configuration file found at:
Source/arch/arm/configs
It's written in this way something_DeviceCodename_user_defconfig
I need for the above step.. ☝☝☝

Well... This is Mediatek, DO NOT expect the sources to look nice. The configs are scattered through ./mediatek subdirectories, *.mk files are parsed and configs are assembled during build. Unfortunatelly, even if you manually assemble .config you will NOT be able to build the kernel. It is full of dirty hacks (Mediatek) and just typing "make" won't work, build will break.

Hi,
I'm trying to build a LineageOS 16.0 ROM for my device Sony XPeria Z5 compact (suzuran)...
...but, unfortunately I failed with two crashes, that I can't fix:
While building this rom, first hiddenapi crashes at about 87% build progress with a signal 4 and, when commenting this out in the build process, profman crashes with the same error! This is because in both tools the "inserting in an unordered set" failed reproducible!!
I've seperated the call to hiddenapi with all parameters and tried to run this program outside the build process. This is the output:
Code:
/home/bernhard/los16/out/host/linux-x86/bin/hiddenapi --light-greylist=/home/bernhard/los16/out/target/common/obj/PACKAGING/hiddenapi-light-greylist.txt --dark-greylist=/home/bernhard/los16/out/target/common/obj/PACKAGING/hiddenapi-dark-greylist.txt --blacklist=/home/bernhard/los16/out/target/common/obj/PACKAGING/hiddenapi-blacklist.txt --dex=/home/bernhard/los16/out/target/common/obj/JAVA_LIBRARIES/android.test.base_intermediates/dex-hiddenapi/classes.dex

Fixed it by

in my .bashrc file.
