Toolchain

Hi guys, does anyone know if the snapdragon uses any specific toolchain, or is it just a standard ARM gcc cross compiler?
I have the kernel sources, but I would like to get a devel system setup before I get my new phone!
Thanks, Matt.

its the the default ARM toolchain

Thank you Herver...

[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):
https://github.com/LiquidSmooth-Devices/android_device_samsung_klimtwifi
https://github.com/TheMuppets/proprietary_vendor_samsung/tree/cm-12.1/klimtwifi
Klimtlte (T705)
https://github.com/LiquidSmooth-Devices/android_device_samsung_klimtlte
https://github.com/schwabe93/vendor_samsung_klimtlte
Chagallwifi (T800)
https://github.com/LiquidSmooth-Devices/android_device_samsung_chagallwifi
https://github.com/diego-cr/android_vendor_samsung_chagallwifi
Chagalllte (T805)
https://github.com/LiquidSmooth-Devices/android_device_samsung_chagalllte
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.
Common Device tree repo:

Klimtlte:

Chagalllte:
https://github.com/LiquidSmooth-Dev...mmit/5ff21d73a9cad3f7f9cf7f79b29bdbab0d8b2b1e
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:
https://github.com/diego-cr/android...mmit/1fc5135eda985ddc159f8465ee114e67aa5dfcae

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

Thank you very much ,our friend !!!!
woow...for to find the best governor/scheduler/hotplugg.... for best battery-life (with correct performance )

i cant compile on this pc
Has anyone compiled it for the I9195?
if so can i have a copy please as i cant get to my own pc until the weekend.

i think we have to compile it ourselves.

Having in mind the fact that 99% of us won't even dare to think about installing a kernel compiled by ourselves, is there a chance for someone more experimented to compile this kernel for all 3 versions?
I personally only need the lte version, but...
Thank you in advance.

Can not compile (newbie)
I would love to test this kernel and give feedback but I have no knowledge on how to compile. What's the chances on someone doing this with experience? I'm after the LTE version myself, I'm excited for a new kernel to play with. Or maybe someone can send meva walk through guide on his to compile.
Thanks in advance ☺

Has anyone tried it yet?

Could you update the OP so we all know what we are waiting for, change (stable) to its current title etc etc, all I'm seeing is disinterest in this thread. Maybe release a pre-release version so someone else can help you, there is no point to compile this myself or I might as well start my own thread.
Looking forward to your clarification and thanks in advance.

-Y550----> Tested
-Y635
I suggest to use the kernel with MM but if you want to flash it with Lollipop you're free to do it.
Just one notice...If you brick the device don't come cry here, tell it to you're parents
Thanks for the attentio, best regards

Top job mate. Just need cm13 to be stable so I can test it out

In Features: you said USB fast charge
Your mean of fast is it work by charger of 2.1 Ah
or
no it works with 1 amper just some minutes faster

installation not possible
Hi kondors1995,
I followed the installation instructions but it seems that something is not quite ok. I donwloaded both the img (Stalin.img) and zip file (android_kernel_huawei_msm8916-2.5.zip) from your github repo.
I placed them on an SDCARD and then booted into TRWP recovery v3.0.2.
I installed the img file and selected reboot into system.
apart from a neverending boot loop there is nothing.
Any advice?
My device is Huawei Ascend Y550-L02.
Thank you

J700P/j7ltespr [KERNEL]-[Touchwiz]-[6-10-17] Ani-kernel V0.4

This kernel will not be overloaded with tons of I/O and CPU schedulers and useless features. I will test and merge what works best and probably provide 1-2 different options on hotplugs.
Disclaimer: DO NOT FLASH THIS ON ANYTHING BUT J700P latest stock firmware.
It may not brick your device if you do because it uses the ramdisk on the device but it will definitely boot loop at the least.
Update 6-10-17
Version 0.4
Complete rebase. Now using Minz1's base with TONS of fixes from CAF and we are working on merging LTS point releases.
This is the result of I and Minz's work.
This release I was mostly working for stability and optimization again. I haven't merged in any I/O or CPU schedulers yet.
I don't have time to list the features so check git if your curious.
I updated the link to the new repo.
Download:
https://drive.google.com/file/d/0B22ZNBermHGrZjlnUmNFRl9JeW8/view?usp=drivesdk
Update 6-9-17
Version 0.3
Compiled with UberTC GCC 5.3
Stability fixes
Added intellli-thermal
Anyone have any feedback or suggestions/questions please feel free to comment.
Version 0.2
- SAMSUNG_RESTRICT_ROOTING disabled (I forgot to disable this on the first build). Root works fine now. SuperSU root would work anyway but works better now with no issues at all
- More low level optimizations. Check git for details. Faster, power efficient, etc.
- Compiled with UberTC 4.9 instead of the included arm-eabi 4.8 toolchain. Will be switching to a GCC 5.x or GCC 6.x UberTC or Linaro toolchain next build, or two.
- Dynamic Fsync.
- Powersuspend driver​.
- CPU frequencies can be changed and set permanently in kernel Adiutor.
- Kcal screen/color control.
- BFQ I/O scheduler.
- Random fixes here and there.
Check source for all changes.

This release I was mostly working for stability and optimization again. I haven't merged in any I/O or CPU schedulers yet.
I don't have time to list the features so check git if your curious.
I updated the link to the new repo.

Update 6-9-17
Version 0.3
Compiled with UberTC GCC 5.3
Stability fixes
Added intellli-thermal
Anyone have any feedback or suggestions/questions please feel free to comment.
Version 0.2
- SAMSUNG_RESTRICT_ROOTING disabled (I forgot to disable this on the first build). Root works fine now. SuperSU root would work anyway but works better now with no issues at all
- More low level optimizations. Check git for details. Faster, power efficient, etc.
- Compiled with UberTC 4.9 instead of the included arm-eabi 4.8 toolchain. Will be switching to a GCC 5.x or GCC 6.x UberTC or Linaro toolchain next build, or two.
- Dynamic Fsync.
- Powersuspend driver​.
- CPU frequencies can be changed and set permanently in kernel Adiutor.
- Kcal screen/color control.
- BFQ I/O scheduler.
- Random fixes here and there.
Check source for all changes.

Big shout-out to Minz1. He helped me get the WiFi working (again) so otherwise this may not have even been possible. It was really kicking my ass.
