[Q] Modified Kernel for Galaxy Tab

Been a while since my last post
is there any modified Kernel for the Tab ? I've seen a Galaxy S runs like a fart on youtube " 1.6 Ghz "
my question is : is this kernel adjustable for the tab ? is there a running project in XDA to make this happen ?
thanks a lot

I have compiled both the AOSP (Android Open Source Project) and the Samsung Galaxy Tab open-source code, but I'm happy with JM6 so far, and I guess I am not brave enough to flash self-compiled critical components, I had enough problems with just self-compiled apps

flashed self compiled kernel resulted in panic
I flashed a the open source basekernel with the galaxy patch from samsung and got no joy. Nothing but kernel panic. Fortunately I was able to flash the original zImage back. Any insight on configuration parameters to use. I just did a stock make.

How did you load the system.img and data.img out from AOSP? I've compiled and can't figure out how to load the images.
Thanks

Im actually going to wprk on making a kernel oc'd just need a few tips ive done linux kernels before but the difference is i dobt have the source does anyone have the source to sprints firmware?

If anyone actually releases a stable 1.5GHz or higher kernel, I'll definitely donate $50 for the work, and I'm sure others will too.

thanks op..
looking forward to this though original is due in 1 or 2 months.:angel::angel:

Hope to see it soon! Thanks

The real question is :
Will you port it or do you ask for someone to do it ?
Because this is confusing :

thanks for this

So what is this thread about ? gonna port and nothing there !! just for thanks ?
am i missing something ?

Guys how can you believe this ?
Just look at this guy's profile....
He doesn't even know what op is and he has posted warez twice ...
He has also used abusive works.
And there is hardly any possible way to port over note 3 firmware to note 2. Even if something was even possible, it would be really very buggy.
Seriously you should have reported instead...
Look at the attaches images and don't forget to report.

[Dev Info] [Deathly Kernel] [AOSP] [Lollipop 5.1.1]

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)
Klimtwifi (T700):

Chagalllte (T805)

https://github.com/Andrewt12/android_vendor_samsung_chagalllte
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

The f2fs version in the carbon build is not updated like it is now so i can not guarantee it works the next build will work though

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

[Kernel][MIUI] AFTERSHOCK (Santoni)[March 9]

/* WARNING*/
I will not be held responsible for anything that happens to your device after flashing this kernel. If you don't know the basic procedures of flashing/modding/unbricking your device please stay with stock MIUI.
/*Features*/
* Built using official sources
* Synced with stable Linux-3.18
* Wake gestures: doubletap2wake & sweep2wake
* Sweep2sleep
* Bfq I/O scheduler
* Underclocked both clusters to 400MHz
* Custom userspace voltage control
* Sound control: headphone digital gain & mic gain
* ChaCha20 based CRNG backport from Linux-4.9
* Sdcardfs synced with AOSP-3.18
* EXT4 FS synced with AOSP-3.18
* arm64/crypto backports from mainline Linux
/*Installation*/
* Make sure you are on stock MIUI kernel before flashing
* Flash kernel zip with twrp. No need to wipe anything.
/*DOWNLOAD*/
https://drive.google.com/folderview?id=1SClj6ZWSkVBLWHYFvwdKpH-eZ0r7yC95
/*FAQ*/
*Will you add tons of those cool sounding custom governors/schedulers?
- No. Interactive & bfq ftw.
* Will it work on custom roms?
- It might work but expect things to be broken
* Will you add custom rom support in future?
- I'm a hardcore MIUIer. So no.
* Will you add overclocking?
- I've already unlocked the max available frequencies from caf i.e big - 1.49GHz/little - 1.2GHz. Beyond this I believe it's completely useless on modern chipsets.
* Will you add QC 2/3/4/5/6....∞ support?
- No
* How power efficient is your kernel?
- Just don't expect the battery life of an inverter.

Nice to see you here sir

Is it Volte supported?

I am on Xiaomi.eu latest and Touch not working and firmware is V34 also tried V33 .

Waiting for Oreo support

nice someone caring for our device

Appeared in the row of the second SIM although it is not.
Appeared in the second line SIM, although it is not. Need a solution. In the rest of the until good core. I test further.
P.s. If you put the SIM in the first slot, then all is well.

anyone tried this?

Yes.
It works better than stock kernel IMO. smoother and better battery life. I've been using it for the past 3 days and it's stable.

thanks, mate. I'll try and see how it goes

Will bootloop with NXP 7.0, which is also not supported (but worth a shot).

works like a charm. good for gaming too. FPS (framerate) stable at all condition while gaming no frame drop at all.
but network lil bit unstable then stock kernel (wifi n mobile data)
thank you sir 4 your hardwork
waiting 4 next update

someone tested on LOS 15.1?

I have installed this kernel yesterday.
I think by using this kernel, when used, the battery feels more efficient, smooth performance.
but when the phone is in a state of stanby I think the battery endurance is the same as I use stock kernel.
by the way i am using rom aosp ex latest version android 8.1
