[KERNEL] [GPL] [4.4] FuguMod kernel for nexus 5 (secure)

FuguMod is a secure, open, reliable and no nonsense kernel
This is probably the only custom kernel for the Nexus 5 which adds security instead of removing it.
Current features are:
- compiled with linaro gcc4.7.4
- various small fixes
You can download the kernels at:
http://fugumod.org/nexus5
Source and changelog can be found here:

Flashing
Kernel zips are intended to be flashed with CWM ot TWRP, if you want to flash using fastboot, you need to unpack the zip and flash the boot.img which is inside
Versions
Kernels are based on the below version scheme
kernel_FuguMod_20131104_r1-4.4.img
20131104 is the date it has been packaged
r1 is the release number
4.4 is the ROM it is compatible with
Stable vs Testing
There are sometimes kernels in testing folder. These may be very stable or may not boot at all. Be sure to have an USB cable and fastboot under the hand if you try one of these. That said, in general, if they stay into testing folder for more than 15 min, they should at least boot and work more or less. I tend to remove non booting kernels from testing folder in less than 10 min (depending a little bit on the speed testers take them), and so if you see them one hour later, you should assume they are safe enough to flash.
So, in general Stable is the safest bet, but Testing may be the best. I, myself, generally run testing one.
Deprecated folder
In general, unless you really know what you are doing, you should avoid flashing those, they are mainly there for historical reasons.
Check for vulnerabilities

Compatibility with hackish style apps
All apps which require direct memory write, access to symbols or memory offsets or modules will NOT work. And, no, don't ask they won't be supported in the future. Example: Arararagi's light is only provided as a module and will not be supported unless he produces a patch.
Security
If you want good security when your phone is stolen, in addition to encryption, don't forget to turn debugging off. Also, use enpasschanger to change your encryption password, any short PIN encryption can be cracked in a few minutes easily (for example, using my script at http://pastebin.com/Mdu06RZN)
Redistribution
As per GPL, you are authorized to redistribute this kernel with any of your custom ROMs provided you give out the source code like I do. You can link to my github in your distribution site.
However, if you modify the kernel yourself, whatever the modification is (compiling it yourself with a different compiler is a modification), you are not authorized to name it FuguMod, although you can credit me and tell the base comes from FuguMod but you cannot call the kernel itself FuguMod.

Glad to see you here renaud. I loved your Galaxy Nexus kernels.

First test version is now available
If anyone can confirm it was flashed correctly and boots, that would be great.

I'll test it right after the postman makes me happy

flashed kernel_FuguMod_20131104_r1-4.4.zip and it reboots to bootloader.

Hello @renaud.
It's really nice to find a lot of people coming from Galaxy Nexus to the Nexus 5. As the Galaxy Nexus is an oldie (yes, two years), there are less and less threads supported. I hope, you will still support the Galaxy Nexus - but also the Nexus 5, of course. Good to have you in here! :laugh:

I suppose you meant you flashed with fastboot.
Whatever, till how far does it go?
I am wondering, did you unpack the zip and flashed boot.img through fastboot, or did you flash the whole zip through fastboot??

I'm glad you got the new nexus because I've been waiting for your kernels for awhile now.

tried out your kernel, alot of nice features but stock seemed to run faster. cant wait to see what the community has to offer over the next couple of months. pushing the phone to its limits / extending battery life.

Thank you for confirming that it boots. Currently it has no features except being smaller than the stock one. I was waiting for the boot confirmation before developing.

Nice to see you again Renaud. Glad to be owning a device you're deving on again.

I have now received my N5. Real stuff will begin.

OK, thanks for some reporting as booting, but in fact it does not because my img doesn't support dtb yet.

Glad you got the phone and now hopefully fugukernel updater will work for this phone.

I was not doing it myself, but I guess I can ask for the code to not have to rewrite everything by myself

r3 is out.
It boots and is compiled with linaro GCC 4.8
Further optimizations are on the road.

I am looking for this too. You can download the kernel source from samsung. I wonder whether, if you build without reconfiguring, you end up with the stock kernel. I would try doing this and only changing selinux mode if I thought there was a reasonable chance it would work. Did you try this kernel ?
http://forum.xda-developers.com/showthread.php?t=2725193
I have not yet. But I have zero interest in performance tweaks that might reduce stability.

i'm currently using it and helping the dev wherever i can. selinux is disabled on that kernel, so i'm running linux deploy just fine.
i'm not sure about compiling the kernel from source because i don't have a linux box and i'm scared of something going wrong if i flash or configure it wrongly BUT if even anyone can show me the guide to doing this i would be very grateful

I was trying to edit my last post because I saw that you have tried that kernel.
I have spent way more time compiling kernels over the past 20 years than I care to, which is one reason I haven't tried this task yet. I flashed the pre-kitkat selinux permissive kernel a while back and it simply wouldn't boot. I had saved the stock kernel with online nandroid backup. I reflashed stock kernel and there was no problem. I guess, the same would happen with an any unbootable kernel. I never have built an android kernel though.

Here you go guys, try this.. Stock KitKat kernel with SELinux in permissive mode and Knox removed: d-h.st/uCX
EDIT: slight update with NTFS support / HTCP and Multi-core scheduler support.. all completely stable as they're already in the kernel just not selected
EDIT 2: http://d-h.st/ziH - V3 [19/05/2014] (fixes a small derp in ramdisk)

samsungs opensource website is so slow, it would literally be about 5 hours of download time to get the source, I can do it but it'd be next week now

Thanks, that would be great, no rush at all, take as much time as needed. There are quite a few users who have asked for this for a long time, but a severe lack of p605 developers has meant it has not yet eventuated. Happy to shout you a beer or two for the option of linux on the p605.

[UNOFFICIAL][KERNEL] Custom kernel (codename Noire) for SM-T560NU (CM14.1)

This release is only tested on the SM-T560NU USA (gtelwifiue).
This kernel is based on vince2678's port of LineageOS, with a couple of updates and optimizations.
This kernel has only been tested with vince's cm14.1 releases.
Flashable zips use a modified version of the AnyKernel2 system. While only tested on cm14.1, it may work on other ROMs, since it does not modify your initrd.
Very special thanks to vince2678.
Without his effort on this device, this release would not be possible.
Updates:
2017-06-10:
First build for CM14.1
Features:
DriveDroid Mass Storage and CD-ROM Support
Built with gcc-linaro-4.8-2015.06-x86_64_arm-eabi toolchain
Additional CPU optimizations
Updated CPU assembly optimizations
Various security patches
XPad (xbox 360 and xbox one) gamepad support
Known issues:
None
How to Install:
1. Download the latest release zip
2. Transfer zip to your device (or skip this step if sideloading)
3. Reboot into TWRP Recovery [Volume Up+Home] (If you need TWRP, first install mine or vince2678's.)
4a. Find the zip in the TWRP install browser, and install it
-OR-
4b. Sideload the zip using adb.
5. Reboot to system and enjoy
How much faster is it with the new optimizations?
Standard Kernel (click for full benchmark):
Noire Kernel (click for full benchmark):
What does "dirty" mean?
Whenever you modify a git repo and do not commit the changes, it will flag the kernel as "dirty".
Rather than forking the git repo, I use a clean copy of vince's repo, then apply my patches over it.
Because this isn't really how git was designed to be used, the build system sees it as "dirty".
It is nothing to worry about, as it is not harmful in any way.
Getting the kernel
Releases can be found on my site. (Check the header on the download page for a link to the source directory for tools to build your own):
https://files.persona.cc/zefie/files/cell/SM-T560NU/kernel/cm14.1
If/when there are more than one release, the most recent release should be on top, but verify the Last Modified date to be sure of the latest release.
Also be aware you will need to reflash anytime you update the main CM14.1 OS, as it will overwrite the kernel.
Bugs and issues
As vince's CM14.1 release is a rolling release, depending on many different sources, unexpected issues may come up in either the upstream code, his code, or my code.
Before submitting any reports to vince, be sure you are using his kernel (reflash the cm zip without flashing mine, preferably with a clean install)
Before submitting any reports to me, be sure the issue is not caused by the current release of CM14.1 (aka doesn't happen when you try the above).
No warranty is implied or provided. Be sure to have backups before flashing. But this is a no-brainer.

bump, because new release and target (was cm13, now cm14.1)

This kernel helped me to finally have USB OTG working by default, great job! :good:

Can you give us more detailed info about optimizations? Does your kernel have any impact on battery life?

Click to expand...

I haven't tested thoroughly but they shouldn't.
The optimizations are some patches that update the arm assembly functions to use features available in our CPUs that were not previously used.
As well as compiling while telling the compiler that we are using a cortex-a53 (in armv7 mode) (by default it just compiled generic armv7 with old armv5/6 assembly).
In short, they aren't overclocks, just using more of the processor's full potential, which is already sitting there doing nothing. Therefore, it shouldn't have a huge impact on battery life.
The CPU patches are here: https://files.persona.cc/zefie/files/cell/SM-T560NU/kernel/common-source/cpu_opts.patch.xz
Fun fact: Our CPU is actually armv8 64-bit, but we can't use it because we depend on Samsung's proprietary binaries, which are compiled in 32-bit (armv7 mode)

Hey,
I'd like to Install this ROM, but obviously i get the message that it's not supported for my Device (in TWRP on flash attempt)
Mine is from the EU so, probably why..

No.
Unfortunately, Samsung made several hardware changes, including the CPU, when they brought this device to the USA.
You could almost think of the SM-T560NU as the "SM-T560 New".
It is a newer model with revamped hardware, and thus not compatible with ROMs made for the other.
Sorry.

Honestly none of my patches do anything USB related, except DriveDroid, but that lets the tablet be a device (by hosting disk images), not anything to do with connecting a device to it. Therefore, I cannot take the credit for that. Vince must have fixed it in his kernel. I built this with the latest code at the time, code that may have been more recent than the last lineage build of his that you tried.

I tried latest build and a few older builds, on every I was stucked in the loop of mounting and unmonting USB device. I only managed to enable USB OTG when I installed StickMount. It seems Drive Droid does the same. Will you continue work on this kernel?

I'll update it if there are any necessary updates for performance or security, or any issues are found, but for now it seems fairly stable and should be alright for a while.

Tnx for detailed answer. Btw, I tested your LOS 13 build and it's very smooth and battery life is great. Only issue I encountered so far is when charging offline, screen doesn't go off and there is no charging percents showed. Also, can you sync with the latest LIneage changes? Can you replace stock browser with the Jelly and stock camera with the Snap camera?

The thread for that is over here:

Also, I am unable to reproduce the issue with the screen not shutting off. There is no percentage, but my screen shuts off while locked when charger is plugged in. Percentage and timeout can probably be configured in settings. I sync with Lineage every update. An update will come sometime this month with July's security patches.
As for replacing stock apps, I'll look into it. As the thread says, this is mostly for my use, hence why it wasn't publicly announced before. If I find the apps useful I will see about integration.

Wondering if this is still supported?

Should still work. I haven't messed with the SM-T560NU in a while. If I recall the Lineage build system was creating broken builds, I'm running 14.1-20171121-NIGHTLY-gtelwifiue and Noire Kernel still works with that.
As for newer builds, last time I tried (some time between xmas and new years), all of the more recent Lineage builds would not boot, with or without my kernel. If trying newer Lineage NIGHTLYs, try without my kernel first, then try with if it does boot.
Vince has kinda abandoned the SM-T560NU, although I'm not sure it is a fair reason to abandon us, because we didn't test on a completely different device, but his choice is his alone, and as such, without him working on Lineage, the newer builds are likely to stay broken unless either he comes back to fix it, or someone else takes over (don't look at me).

[REFERENCE] Umbrella Kernel

WARNING:
This is not a post targeted to end users. It is a development reference. If you expect any installable download or even added features out of this thread, please close your browser. Thank you.
What is Umbrella?
Umbrella is a project that aims to make the kernel sources that HMD released for Nokia 8 Sirocco (A1N) compatible with the Nokia 8 (NB1). The idea behind this is to replace the outdated 8.0 kernel sources that HMD released for NB1 with more up to date ones that are used in the 9.0 builds for Nokia 8 Sirocco.
Why do this, you might ask. Well, the answer is simple: The devices are so similar that HMD / FIH already have their kernel sources in a shared source tree. You can validate that yourself, by downloading the kernel config from a stock NB1 kernel (under /proc/config.gz), unpacking it, and searching for the commended entry "CONFIG_FIH_A1N". What umbrella does is take the sources that were released for A1N, readd all device specific files for NB1 (they were pruned) from it's original kernel soure, and integrate the stock kernel config (also called defconf) from NB1.
Doing this also lead to some other small quality of life improvements that are not directly relevant to an end user.
Umbrella contains the latest changes from linux-stable (v4.4.179 at the time of writing, compared to the stock v4.4.153), and Qualcomms Codeaurora upstream
The WiFi driver from Qualcomm is compiled directly into the kernel, instead of being loaded as a module. This allows you to flash umbrella based kernels to every build version while keeping everything else working correctly. The stock kernels use signature enforcement, which means that the wifi module that is loaded from the system partition has to be signed against the kernel, which is not the case for every custom kernel or even the kernels that were built for a different security patch.
Unlike the officially released kernel sources, umbrella does not have stupid typos in it's device trees that cause the phone to display white bars on all of your screen etc.
Umbrella disables the block that FIH put in place to prevent users from rebooting into EDL mode from within android (using adb reboot edl).
Umbrella also includes a patch that causes the device to not reset it's entire memory when the kernel crashes, therefore retaining the last kernel output log, which can be used for debugging
You can compile the kernel with compilers newer than GCC 4.9 (not clang though), without having it immideately crash at boot.
It includes a tool that automatically sets up a crosscompiling environment for the kernel.
What Umbrella is not
Umbrella is not a project to add significant new features, or the ability to tweak things beyond what the stock kernel already offers (which is technically not that bad). It aims to be a reference kernel, a base for (potentially) other kernels that are based on it and add those features. I know that that is kind of a broad goal, considering I am the only one who seems to do actual development for this phone, but who knows. Having a lower entry level might help in case someone is curious and wants to get into kernel hacking. And I would certainly be happy if I wasn't the only one developing for this device.
If you want Umbrella to contain features like:
Overclocking
More governors / schedulers / whatever
Color / Sound / whatever control
Wakelock blocking
etc. etc. etc.
then please Alt-F4 your browser right now. Ok, don't do that but at least please don't request it because it will make you get ignored, nothing else.
Why the name Umbrella?
While I developed the initial prototype I watched through 3 Resident Evil movies, and this is kinda a zombie project, so I think the name fits quite well.
Why are you posting this?
I am posting this because I am hoping that it will be useful for anyone that would like to get into kernel development and tweaking without the hassle that comes with setting up the kernel sources that are released by HMD.
But, one disclaimer: I am not a kernel developer. I am a curious CS student suffering from a bad mix of too much time and stupid ideas that solve stupid problems. I am trying my best to produce something useful and be of help, but please don't expect wonders from me, thanks.

Nice. this will likely be useful in the future

Updated the umbrella source to the latest 4.4.180 kernel, and May 07 CAF tag (LA.UM.7.4.r1-05100-8x98.0). Also readded some NB1 specific code where it was missing (discovered by doing a diff against the 5140 kernel source that Nokia recently released).
Just in case anyone actually cares about it

Kernel sources which is used on pie has been released officially. Finally, we have an "original" kernel and we've got closed one more step to custom roms.

The only difference are the device tree files (which still contain typos that break the display), and of course all modifications I made to the sirocco kernel source that Umbrella is based on (wifi driver, EDL mode reactivation, upstreaming, etc.)

So, are these new codes broken like 4.84?

I wouldn't call Nokia sources broken, but I would call them incomplete, outdated and impractical to work with. And that hasn't changed.

nb1_defconfig is for Nokia 8

Can somebody help me? I have built Lineage OS 16.0 for the Nokia 8 with the Umbrella Kernel. However I am facing issues with getting it into work. Firstly TWRP fails to flash it with error 7. I am including the recovery.log file in case anyone wants more detail. I then proceeded to extract the payload.bin file, and flashed boot.img and system.img seperately. However that didnt work either as my phone got stuck at the Bootloader unlocked warning screen. If anyone is interesteed I can upload the .zip outputed by the build

hey, did you wipe userdata before flashing this? I think you need to do that, like when switching to using GSIs.
also, have you checked this https://github.com/resident-nokia/twrp? Specifically the fstab file for NB1.

Thanks for the suggestion. I have flashed GSIs before but never had any problems. Also I cannot find any userdata partition in TWRP. I asked in the Lineage OS discord and I was told that probably that TWRP image is broken. I am confused

that's the data partition, if I'm not mistaken ?*
which twrp image are you using? Maybe try Dorian's latest?

Yes I am using the latest TWRP. Before flashing I erased the data partition but still the error persisted

[KERNEL] [Android 12] [v12.9] MVK - Maximum Velocity Kernel

For those familiar with Velocity Rom this is the kernel I build for it. Velocity hasnt been on XDA as a rule so Im sure not many are familiar. Velocity is my personal Rom Ive been building for years and have shared with all that are interested. This isnt and will never be an "official development project" but will always exist as long as I continue to develop Android roms.
Velocity is focussed on speed, stability, and efficiency and not on adding every imaginable feature. As this is my personal Rom it will have everything I deem useful to me and/or that doesnt compromise the goals of the project.
I dont add every conceivable governor, I/O scheduler, or other user tweakable options. In fact, I typically remove all the options and keep the best. This is designed as a plug and play kernel, not something to be changed. Its also not designed for other Roms.
Please do not ask for features, ETA's, or related. Again, this is my personal kernel for my personal Rom and will be shared accordingly. That said, I do encourage healthy, friendly dialog in my threads.
Flashing instructions
1) Reboot to bootloader
2) Fastboot boot 'bootimage_name'.img to make sure it boots with no issues
3) Reboot to bootloader again
4) Fastboot flash boot 'bootimage_name'.img
5) Buckle up for safety - optional of course

This is basically a crosspost from the 3a XL forum. I only own the 3a XL but Im told this works fine on the 3a as well. There are both patched and unpatched boot.img's available depending on whether you want root or not. There is a lot more info over in the 3a XL thread if you have any questions.

New build up....see changelog. This was built from November security patch source and I havent tried it on the October build so ymmv if flashing on a build prior to November security.

New build up. See changelog for details. Also Sargo will now be getting its own builds vs sharing a Bonito one. Download links have changed in the OP.

Are there some changes except for the name? I didn't realise and flashed the bonito build, but it works fine on sargo.

No, the boot images are now built using the respective devices but for all intents and purposes its the same build. This change was mostly for allowing me to better keep track of downloads. Its possible there are minor differences based on device too but as they both work interchangeably I doubt its anything big, if at all.

New build up.....see changelog.

Anyone interested in (or willing to) flash and test kernels prior to releases please PM me. I can always use people to help especially as I start looking at more experimental changes/optimizations.

New build up. Substantial changes on this one.

Can this kernel can be flash with kernel tools?

What's the difference between the two kernels ?

Don't know what the inside differences are, because I'm not a developer, but mvk seems faster for me and more battery friendly at the same time. So I use this kernel for now.

I wont speak for Flar as I dont know him but from a code standpoint these are 2 very different kernels. My goals (as stated in the OP) are maximum performance without sacrificing efficiency and stability. I delve deep into the experimental and push things to their limits. So while both share the same (or similar) base the additions are very different.

Hi ctfrommn,
I'm seeing this error when trying to boot from the img. Tried 10.16-10.18 magisk and unpatched, sargo and bonito.
fastboot boot MVK_Sargo_v10.18_magisk_patched.img
Sending 'boot.img' (26872 KB) OKAY [ 0.723s]
Booting FAILED (remote: 'Error verifying the received boot.img: Invalid Parameter')
fastboot: error: Command failed

When I flash the img and reboot the 3a goes to fastboot mode and shows "Enter reason: error boot prepare"
Any idea why?

Keep it coming

Anyone willing to give a comparison of this vs. other custom kernels that they've used?

New build time. I just spent the last month rebasing and rebuilding this. Everything was rethought, tested, and only kept if it objectively and subjectively improved either performance or efficiency. This is up to date with the latest AOSP and Linux kernel sources. This is built off January security but "should" work on older builds as well.
See changelog for changes and enjoy.
