Hi,
Could you generalize a download from OmniRom without kernel ?
A lot of OmniRom users a poweruser and used another kernel

No. The included kernel is the only supported configuration, and it will always be this way.
Why? Anything else results in a testing nightmare. It's bad enough when we change out blobs that require a matching kernel change and a maintainer's thread gets flooded with "it's not working with X kernel any more".
Anyone can submit changes to Omni's kernels for review in gerrit, so that leads to the question:
1) Why is the maintainer of an alternate kernel not upstreaming to gerrit? What are they hiding?
2) If a change was submitted to gerrit, why was it rejected? In many cases, some of the "features" of alternate kernels are highly dangerous (such as disabling per-file fsync and allowing devices to pull more than 500 mA from a standard USB host port)
This thread will be about changes i have made to the device trees for the t700,t705,t800,t805 which should in the long run make maintaining the variants a lot easier the primary changes i have done are combine all 4 of the variants into 1 kernel source as well as make a common device tree so they can inherit everything that is the same across devices.
Kernel Changes:
The Base kernel from Cyanogenmod supports klimtwifi (T700) and klimtlte (T705) to add support for chagallwifi (T800) all that is needed is to add its defconfig which is this file
https://github.com/LiquidSmooth-Dev...arch/arm/configs/deathly_chagalllte_defconfig
To add support for the Chagallte (T805) it was a little more complicated for to do but very simple for you guys for a little background T805 is exactly the same chipset as the other Galaxy Tab S's except for whatever reason Samsung decided to put a different gpu (Midgard_wk04) everyone else uses a mali_t6xx.
The stuff developers actually need to support Chagalllte are the following:
Defconfig:
https://github.com/LiquidSmooth-Dev...arch/arm/configs/deathly_chagalllte_defconfig
The GPU addition commit:
https://github.com/LiquidSmooth-Dev...mmit/c8e96e86c902cbc2b13d34e7e7158623eacf5d84
Bam that was easy now any kernel can support all 4 main variants of the Tab S
Device tree and vendor repos
First part i want to place links to all of the stuff that's needed to make a rom for each device in one place.
(Disclaimer the trees will be LiquidSmooth but it is very easy to convert them to any rom)

WIP Common Device Tree:
When bringing up support for LiquidSmooth for these devices i noticed that they are all pretty much copied each other (which makes sense) but because of it there was tons of duplicated code between the devices so i decided to make a common device tree so any future code changes could be placed in one place instead of over 4 device trees. This is still a WIP because i do not have all the devices so i can not test them all in my eyes they should all work fine. The common device tree will also hopefully will be rom independent so no changes would be needed on a per rom basis. I can for sure say klimtwifi and chagallwifi work with my common tree, Chagalllte and klimtlte need to be tested still.

One more improvement that myself and @diegocr made was finally made a pernament fix to Chagallwifi's (T800) wifi issue he made a custom release tool in the device tree to make it so you would not have to manually patch it every time. I then took that and fixed the root of the issue which was that the vendor repo was not putting the files in the right spot. (My orig commit also did egl but that was not needed) the commit that did it is this:

Deathly Kernel
I have had a deathly kernel on most devices i own the goal of it is to get as many options and features into a kernel but still be stable. For the Tab S i took the aosp cm base and have updated it against kernel.org from 3.4.105 too 3.4.108 along with pull in a bunch of features from other exynos 5420 devices
As you read above i have made a common tree which changes the ramdisk so i have to provide two zips one with the new format one with old format currently the only rom that i personally have built with the new version is the latest klimtwifi and chagawifi all other roms will boot loop with it so use the old version
Currently i only have flashable for Klimtwifi (T700) i will generate the others once i get back from my trip.
New Ramdisk option:
http://www.drdevs.com/devs/teamliquid/Kernels/klimtwifi/New_format/
Old Ramdisk option:
http://www.drdevs.com/devs/teamliquid/Kernels/klimtwifi/Old_format/
Features of the Deathly kernel:
Will support all 4 main tab s devices (will add support for the US carrier variants if aosp is brought up)
CPU Voltage Control
CPU OverClock/UnderClock
GPU Voltage Control
GPU OverClock/UnderClock
MIF/INT Voltage Control (I will not show how to configure this if you know how too then you can)
Wolfson Sound Control Thanks to oloendithas for fixing it for stereo out
UKSM instead of KSM
Added the following IO Schedulers: fifo, fiops, sioplus, tripndroid, vr, zen, bfq (Default)
Full f2fs support updated off the mainline (Stock cm kernel has limited support)
Modified Thermal Throttling temperatures for all devices so hopefully they won't get as hot (WIP)
Android Logger disabled by default can be enabled over sysfs
Exynos thermal exposed to sysfs
WQ power efficient workqueues (Still need to apply in more places)
Frandom Support
Readahead bumped to 256 from 128
Details how to configure all of the features i will add the rest once i come back
GPU Configuration:
To configure the max or min gpu frequency you would go to either of the following files in a root enabled file browser and change the value inside
/sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq_gpu
/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq_gpu
The allowed values for the files are as followed:
667, 600, 533, 480, 420, 350, 266, 177, 100
T800 owners the default min gpu freq is 100 on all roms if that causes issues raise the min freq to 266 you will probably not notice a battery decreases if that still does not work let me know i'll take a look at the code.

Thanks, working great on CM12.
Thank you man.. Im glad someone finely separated the device tree... And specially Happy about a new kernel that I can use in my Project Roms.
With all Credits going to you of course.. thanks again.
Hey mate, thanks for this!
I'm a little unsure about the new and old ramdisk thingy.
Running aicp on my klmitwifi, new ramdisk is cool?
Will try anyway, but let me know please!
Edit :
just checked, didn't stupidly before, Looks like the kernel is baked in your AICP rom.
Thanks again for your hard work!
Edit edit:
tried the v02 on the rom mentioned, had to revert cause I was having many ui fc.
Used new ramdisk version, could be that or I should have done a clean flash maybe?
Thanks for this, hopefully if fixes the lag issue for me on CM12 with the T800.
Thanks for all the hard work, grid .1 and .2 both worked perfect on bliss rom
Thanks, I will use your kernel on my chagallwifi SlimLP builds
Wait, does the Deathly kernel already in CarbonROM for T700 have F2FS support already? Or is that for the New Version and not yet built for klimtwifi? Thanks

OK, thanks. Hope your enjoying your time off... :good:
I'm going to backup your kernel and try ashyx's new build released today. Its closer to stock but has F2FS support also. Then I will test yours once its updated. Loving this new tab of mine, almost forgot how much fun it was trying to find the sweet spot on a device, lol. My Nexus 7 found its sweet spot a long time ago and now its just a plain ole boring tablet. hehe

Hi,
So as many of you already knew - I'm working on porting CM13 onto my NU3001.
I has it on my desk table, so I could work on it during my days. (I have another NR3001 installed in my car)
I already made some work for our unit SW. This is quick screenshots. Sources based on xdAuto and CM13. This is a very BETA and many things not working for now.on.
Why? : When I realize than CyanogenMod 13 (6.0.1) works on my Motorola XT1080 better than stock - I start thinking of porting CM13 to our device. And when I have spare set - I start porting.
How? : I took easiest way - try to do not modify kernel a lot, instead adopt bionic and other libraries for out 3.0.36+ kernel.
Currently working staff (it is very beginning):
1. Recovery TWRP 3.0.2
2. CM13 (LineAge OS) booting.
3. Graphics working (there is some blinking present).
4. Wifi working
5. Android audio working
6. Bonovo Radio working
4. Most of the rest is on the way (GPS, BT, rest of Bonovo apps)
UPDATE_1:
I decide to do not stuck with CM 13 and switch to AOSP N release (7.0) (mostly because on my daily job - we also going to Android N, so it should be more familiar to me now)
Currently working staff:
1. Recovery TWRP 3.0.2
2. SELinux needs to be carefully ported (kernel part), cause starting from 7.0 is can not be disabled (as I did for CM13 to easy port)
During this port I will try to minimize inpact to AOSP release, so any future updates should be much more easier.
For you to understanding of amount of needed work - kernel already has 100+ patches on top of xdauto release. Approximate left about 250-300 patches to revise/port.
Android 7.0 port abandoned because of bigger and bigger amount of work need to be done to port SELinux on top of our outdated kernel.
UPDATE2:
I setup review build environment, so who want to look at NOT-FULLY-WORKING CM13 could download sources and binaries. I do not provide instructions how to flash it, because who wants to look and contribute already know hot to flash, and who doesn't probably don't really want this NOT-FULLY-WORKING CM13
UPDATE3:
So I finally managed to get functional networking. So now Wifi working, internet working, display working.
I starting to port all necessary items. No more 'hard' showstoppers so far.
New build (I believe it is build number 5) should be ready in an our on build server, so I could test it more fully.
UPDATE4:
Cause CyanogenMod is no more maintained - switched to it's successor Lineage OS 13.0, starting from build 8
UPDATE5:
Build number 15 has working audio + radio
UPDATE6:
Most of Bonovo changes ported, new build 20 ready.
This build contains zip file which should be flashable via twrp, but I not test it this way.
Issues remaining so far(most noticeable to me):
1. Display flickering (my suspect is to vsync/fence mechanism slightly changed in Android 6.0, need to investigate)
2. HW Volume buttons not working on device
3. No audio In
UPDATE 7:
Starting from build 23 following images available:
cm_rk3188-ota-XX.zip - update to use via TWRP
nu3001-la-cm13-XX-userdebug.tar.gz - build image for flash via command line rkflashtool under linux (full or partial flash)
rkflash_nu3001-la-cm13-XX-userdebug.zip - Full image to be flashed via PC GUI RK Batch Tool.
kernel_nu3001-la-cm13-XX-userdebug.tar.gz - just kernel with debug symbols for debugging purposes.
To just download sources:
repo init -u https://gerrit.nc.org.ua/manifest -b nu3001_cm13
If you plan to contribute - login to Gerrit with GMail, push your SSH public key, choose login name and then do:
repo init -u ssh://<user>@gerrit.nc.org.ua:29418/manifest -b nu3001_cm13
Builds will be available on Jenkins build server (login also via GMail, PM for access grant on current project stage):
https://jenkins.nc.org.ua/
1.5 GB folder on MEGA
4 files
mega.nz
Please do not spoof this thread with questions like "When?", I will try to post updates regularly in this message.
This thread created is mostly to exchange experience with this build once it is published (issues, TODOs, etc)
**Reserved **
First!
Second! Lol
I'm not a developer so unfortunately I can't contribute, but hopefully those who can will.
At the very least I can beta test when its a little more complete.
Android port system less complicated than the application Bonovo.app and MCU. Good luck and patience.
Black're a legend !!
Your project is great !!! see Android 6.0 on Carpad would be great.
Thanks for the great effort you make for all
Woooow great !!
Good luck
nice one, i hope a very important feature:
"that can be use apps, which require android +4.4.4, like lollipop"
I say that because android auto "stand alone" coming soon, so if will be possible install this app in the radio, we have android auto pure, ( not automate that is awesome but is not the same like original ), and maybe mp3 stuttering from usb can be solved in this rom.
keep up work!
Thanks for the sneak peak, looks promising. I'll gladly help sponsor a new device if you happen to brick yours. I love this headunit and how far the community has gotten in supporting it.

NU3001 or ROM ? if you want NU3001 - you should go to aliexpress from wiki link. If ROM - it is not ready yet. I have half-working CM13.0 - no connectivity working (wifi, bt) so it is useless for now, and Android 7.0 porting in progress.

I just put NU3001 to aliexpress search bar and found a lot of propositions, I think there should be available one.
Hi VBlack,
it's nice to know you're making progress on the new ROM CM13. All are rooting for you !! Your work would be wonderful !!
I have only one question:
With the ROM of XDAuto I found an annoying problem that occurs when i turn off and then relight the Carpad.
When the power back very often the Carpad car remains with black screen until i touch it with my finger.
I think the problem is somehow related to the USB ports.
Even with your ROM does this happen ?? When you turn on the car, the Carpad remains ever with black screen ??
Thank you!!

Do you have your efforts posted on github anywhere? Would you mind doing so?
There is a chance I may be working on these devices again after all, and having a working CM provides a *LOT* of possibilities. Namely the Theme engine.
If you would be willing to post your work, I'm sure there are a handful of us who could help with the port.
Thanks,

Nice to hear from you. Sure I will share. Current situation is next:
CM13 - no wifi (looks like netfilter from userspace not match netfilter from our outdated kernel), no selinux (completely disabled), and increased system partition to be able to add opengapps, twrp - works.
AOSP 7 - it is strongly rely on selinux, so i could not just disable it, and now I'm trying to merge new selinux with our old kernel...
So, i will upload CM13 in current state, and continue on aosp 7, if i fail with aosp 7 i will back to cm13. This is current plan.

I update first post with sources and build information
@VBlack, you mention "our outdated kernel". Does this imply that the kernel sources aren't available? I am very interested in this project because I am looking for a head unit with fully update firmware that can be kept up to date with security patches, and some of the Android security patches include the kernel (e.g. the recent "dirty cow" vulnerability).

No, we have kernel sources, but our kernel version 3.0.36 and looks like nobody release Android kernel 3.14 or 3.18 for rk3188. 3.14 and 3.18 mostly used in Android M and N. So combining Android M or N with such outdated kernel is not a trivial task. Because of this incompatibility we currently have all networks issue on this CM13 project.
Kernel 3.0.36 is 4.5 years old. The 3.0 branch is no longer maintained with security patches, and hasn't been maintained in over 3 years. There have been numerous security exploits in the Linux kernel since then, many of which are applicable to Android. Is it worth even persevering with this under such an extreme kernel constraint?

You'd be surprised how many phones in the market use old kernels (3.0 is not too old for Android - it is about 2-3years off from active development).. But true is that Android kernel despite it's version less vulnerable than Desktop one, and has many fixes included (it is does not increase kernel version, like mainline kernel). Because of this it is generally hard to say which security issue will be there for sure. But on the other hand Android N and Android M has SELinux enabled, and Android N could not have it disabled. It is dramatically increase overall security of the system. But for the most of traditional Android user kernel exploits does not produce many harm - it is not a corporate server with sensitive information. And many of them used to obtain root on bootloader locked systems.
So generally for what I have in mind:
1. If succeeded just with CM13 - I have disable SELinux there - it is will be not less secure than original 4.x release - just system/google components will be upgraded, which allow us use modern UI features from Android M, and also adds more compatibility with new applications revisions.
2. If succeeded with AOSP 7.0 - SELinux will be enabled there, so we will have security addition on top of old kernel, which actually will increase security alongside allowing UI features from Android N.
So in any case it is very nice to have.
Hello
For the past couple (weeks) I've been trying to compile Android 10 for tenderloin using the Android 9 sources but it's not going so well. First thing I ran into multiple sepolicy errors and I feel as if I fixed them in inappropriate ways but the errors went away. Other errors regarding camera and audio and such, that are regarding that tenderloin no longer uses the legacy audio format. Made me confused because I used the device sources form Evervolv and DIrty unicorns and if i'm correct they built it exactly the same way they uploaded it. After these errors were wrapped up, I got a error at zipping the rom that it could not zip due to failure of being able to read build.prop. This made me believe that the sources are not correctly formatted. If anyone can help me find a manifest, I can build for all you guys. Please keep tenderloin alive!
Now, I did something and I'm getting plenty of perl errors. Maybe I'm just very unlucky. I'm gonna attempt to reinstall on a fresh drive on my server.
If its anyone's concern, I was building lineage 17.1. I noticed for example, Lineage's "qcom-device" repo was shaped completely differently than Evervolvs qcom-device repo.
This led me to thought that Android 10 is going to be extremely difficult because of all the upstream dev changes that was pushed to Q. If any of you would like, I could probably push out March patches Pie rom because over there I'm mostly safe of complying with the source.
My manifest shape
DirtyUnicorn's device-tree
DirtyUnicorn's device-tree-common
DirtyUnicorn's htc-msm8960-kernel
Evervolv's vendor
And dirty unicorn's atheros wlan driver
I have been changing up the device tree so much, it almost looks ridiculous . From what I heard lots of properties on the device tree haven't been touched for years. Maybe tomorrow I can try Evervolv's Q rom. If you guys can help me build up my manifest, we can push out a fully working Q rom for tenderloin. And it would be just in time when Android 11 comes out. Thank you everyone!
I wish that I could offer any help, but I never tried to compile any Android ROM or for the HP_TP.
To my knowledge the only users that I know that could offer some insight on the process would be:
@flintman
@elginsk8r
Also the LuneOS project could offer some help:
https://pivotce.com/tag/luneos/
If Android Q(10) can not be ported to the HP_TP, then at least P(9) is a good ROM to keep updating that could provide many years of App support.
Theres no reason why exactly it cant,, because lots of roms I hear were built off the original TP sources (From 2011!). It was only around 2016 when guys around here had to change it up so much that they should've been so surprised that it worked. I can try and temporarily maintain P roms until the boys around here push out sources for Q!

To my limited knowledge is all about Hardware -->> Drivers -->> ( Kernel ).
The reason that Bluetooth and camera does not work on newer Android version is due to the old (proprietary drivers) and the Kernel. That takes more dedication and work than the ROM. The same rules applies to the desktop, older processors does not support certain features and the Operating System will not run. It is possible to disable the features in the kernel so that it does not check the hardware and make it run, but it will be unstable.
Everything could be possible with plenty of time, knowledge and dedication.

When I look at the tenderloin source, the script to gather the camera driver is disabled. Camera isnt a huge deal though because its only 1.3 MP. However we use the MSM 8960 kernel from HTC and that is the one m7,, but the one m7 is a SD 600 device so it loses sense. I was gonna get some help with one of my kernel developer buddies to dev a kernel for android 10 for tenderloin. If you see the one m7 has Lineage 17.1 available and even though it doesnt have same chipset, if im correct both chipsets went off of the same assembly line process. Lineage 17.1 for the one m7 also packages it as a "uimage" which is what we use. I believe this was only a very small select of devices. Yeah about that ive been getting so many complaints during build about "mkimage" which should've been a prebuilt tool in the lineage source. Don't know why they removed it, or if our developers added it in by their selves, etc. Anyways I fixed that error by just "allowing" mkimage in one of the permission files in my environment. But yeah i went as far as the build packaging the ROM and it complaining it cannot read build.prop. Note the build.props are generated by the environment , not the source (even though the device data is gathered by the source, its not what im talking about). I even go to the directory it was complaining about and it was all there. One of my friends suggested a permission error. I changed permissions to 777 (rw to all users) and it would still output that error. By that point I trashed my build meaning I may of done something wrong early on. I will let someone else continue building 10 but I will continue building 9 with latest patches.
It will be extremely impressive if any kernel developer will update the HP Touchpad Kernel or tweak it for future release, well everything will stop once Android becomes 64 only.
I am sure you are very well aware, but I will suggest using this built:

I was able to do the following playing around recompiling the Kernel. I recompile almost all the ROM and incorporated the same kernel changes.

The Ramdisk is also very easy to unpack and repack:

There is no need to get the original Camera or Bluetooth working, only sound and WiFi.

I think I probably stated somewhere, but Evervolvs "device" tree would just spit out hundreds of errors, and I fixed this by switching to Dirty Unicorns device tree. I also tried flintman's device tree and it didn't spit out many errors. Thanks for this though.

I have only recompile the Kernel and all of them work, but the correct branch must be use. I can not say about building a ROM, never done it.
But Evervovs Pie by elginsk8r works very well and stable as it uses the same kernel, but the framework is different. I guess elginsk8r will be the only that can guide you on the right direction or flintman.
Have fun learning, it takes a lot of TIME!
I'm kinda new here, so please excuse me if this is not the best place to ask and it should instead be posted in another section.
First, a bit of context: I recently bought a refurbished H910 to practice android development since it was fairly cheap, and after testing its features and unlocking the bootloader to install custom roms, i opted to start compiling a kernel of my own with some changes to begin involving myself with the development side of things. For now, i am using the Lineage OS 18.1 kernel sources on github as a base for the kernel, then after making sure that the kernel compiled, i flashed it into the phone and basically everything works with the only exception being the bluetooth, and maybe the IR Blaster, but that one is working just like the stock kernels on different Android 11 roms.
Now getting to the issue itself in more details... it boils down to the phone's bluetooth refusing to turn on while running that custom kernel of mine on any Android 11 ROM, be it Lighthouse, Superior OS Xcalibur or Lineage 18.1, the bluetooth tile gets stuck on the "Turning on..." icon animation for a while and then returns to the disabled state. Reverting to the stock kernels or even using other custom kernels like Lyb's or Gamma make the Bluetooth work again without needing a wipe, which tells me that the problem is definitely somewhere in my kernel. I could of course test it on some Android 10 ROMs, but the outcome will most likely be the same.
I even took some logcats via ADB Shell but they are kind of broad and mostly explain that the service had some problems with "com.android.bluetooth service has died: psvc PER", followed by a "scheduled restart of crashed service com.android.bluetooth...". Both of which never happen on those ROM's stock kernels, where the bluetooth works as expected. I looked around on Lyb/Gamma kernel sources on github, and there aren't any major differences to the defconfigs for example with the bluetooth driver configuration also being just about the same.
I'm not sure if this will be of any help, but as for the toolchains and compilers, i am using clang 11.0.2 383902b1 as the main compiler, gcc 4.9 as the ARM32 cross-compiler, and gcc from 4.9 up to 10.3 as the AARCH64 cross-compiler, all running on Manjaro. I also changed that combination dozens of times, but to no avail.
So am i missing something during the compilation process? With all those things i already checked, i keep getting a feeling that something really simple is going over my head. Also, i can post the link to my github repository here if needed, there's a branch made specifically to check the BT since it has only the changes made to assure that the kernel compiles.
Edit: The problem was solved!!! It actually comes down to using the exact toolchains provided by the lineage OS source tree for the device (that might be optional, but it's how i managed to get it working) and checking if everything has been installed correctly. It seems some files failed to download the last time i did a 'repo sync' on the source and that was what might have caused this.
