[Galaxy Tab S Original Android Development] shpitz461:
This kernel works great on T800 running PhoeniX ROM V1.6.

I'm running T800XXS1BOK1_T800UVS1BOJ1 firmware.

Got F2FS on the Cache and Data partitions, seems to be working great.

I can flash the kernel SkyHigh above the iron kernel, or do I have the stock kernel?

[Galaxy Tab S Original Android Development] UpInTheAir:
Just follow the instalation instructions
[Galaxy Tab S Original Android Development] vibecatalin:
I'm running too the latest Phoenix ROM with your kernel and it is just blazing fast and stable
[Galaxy Tab S Original Android Development] Rx8Driver:
I think i have your unicorn device. Lol synapse says my ASV is 12 for everything except D3D which is 10. Can that really be correct?

I feel like I'm either very lucky or my ASv is erroneously reported?

[Galaxy Tab S Original Android Development] UpInTheAir:
Probably. You taking about Tab-S (this thread) or Note5 that you used to post with? Most of the Note5 asv are quite good, except mine it seems. ...
[Galaxy Tab S Original Android Development] Rx8Driver:
Oh, yes sorry it's my note 5, smh i probably should've posted in the note 5 thread smh

[MENTION=3511708]UpInTheAir[/MENTION] will your kernel work with new OL1 frimware or do you have to update the kernel T700
[Galaxy Tab S Original Android Development] UpInTheAir:
I don't have your device. ....
[Galaxy Tab S Original Android Development] Neo3D:
Can I flash this on my Note 10.1 v2014?
[Galaxy Tab S Original Android Development] rookie12:
What why this is tab S section not note 10.1 of course not it wont work you will bootloop your tab
[Galaxy Tab S Original Android Development] UpInTheAir:
Could be anything since you haven't provided any useful information to help. . .

Go back to full stock and test. I'm not here to debug ROM mismatch or inconsistencies. If we ever get a source update, will have a kernel overhaul if/when I have time or motivation. I don't have that to update my own firmware right now. . .
[Galaxy Tab S Original Android Development] yakalelos7:
i install the kernel on stock rom and my tab s reboot on the recovery mode any fix?
[Galaxy Tab S Original Android Development] UpInTheAir:
Flash your stock kernel. ..
[Galaxy Tab S Original Android Development] UpInTheAir:
End of the road

END OF THE ROAD

Hi all, I'm happy to have been part of these Samsung Galaxy Tab-S forums for the last couple of years and enjoyed to share and contribute my time here. As some might be well aware, developing for devices not in hand can be difficult, so I am grateful for users constructive feedback and support, without, these kernels would not have reached the current level. :good:

If you have issues with this kernel, please DO NOT PM me regarding and potential fix etc. All info is in OP, and if it doesn't work with stock firmware, then maybe the kernel source or ramdisk base requires updating.

Although I still have and use my Tab, I just don't have the time for further development or support right now. I might (or might not) create a future kernel if Samsung was to release a major update, but please "don't hold your breath" on that ;)

Thank you. and will sure to see you around XDA somewhere in future. :cool:

Happy modding, flashing and tweaking !! :)
[Galaxy Tab S Original Android Development] Heisenberg:
This project has been discontinued, thread closed.

Many thanks to the developer.
[Galaxy Tab S Original Android Development] ashyx:
I was referring to Iron kernel.

I used your kk kernel with no problems, but couldn't implement a working F2FS in it because your source for the T805 wasn't available, so had to use Iron kernel on lollipop which worked fine, no problems except for when using the F2FS file system.

It would run great for a while and then freeze for no reason.

This issue seemed to be linked to the hotplugging implemented in Iron kernel.
[Galaxy Tab S Original Android Development] rookie12:
Any heads up when the t700 one will be out?
[Galaxy Tab S Original Android Development] UpInTheAir:
v1.0 T700 WIFI released

SM-T700 WIFI kernel v1.0 is available for release.

NOTE: I have not personally tested this as I don't have your device variant, so please read the Installation Instructions !!

Thanks to [MENTION=236806]jpearn[/MENTION] for the boot.img so I could extract and mod your ramdisk

Cheers :)

UITA
[Galaxy Tab S Original Android Development] UpInTheAir:
Could some users of 10.5" device please post your boot.img extracted from firmware versions:

T800 WIFI: T800XXU1BOE2

T805 LTE: T805XXU1BOD1

You can download the full packages from either sammobile or samsung-updates

These are the latest, so

without

the boot.img's I won't/can't continue attempt a kernel for your devices. I have other things to do.

Cheers,

UITA
[Galaxy Tab S Original Android Development] b3ltazar:
Pretty sure i have it saved on my laptop will upload sooonn... thank you
[Galaxy Tab S Original Android Development] UpInTheAir:
T700 WIFI kernel is already released.
[Galaxy Tab S Original Android Development] rookie12:
Just flashed it everything is fine untill now
[Galaxy Tab S Original Android Development] UpInTheAir:
Thanks for reporting success. Although method is same between T700 - T705, is easy to make a copy/paste error when modifying the ramdisk.

BTW, please never ask for ETA for anything. I've got nagging users on "ignore" for less ;) This time around, "3 strikes and you're out", you are on strike two ;) Nagging won't speed things up and doesn't contribute to a Development thread. This is not General section .... Thanks
[Galaxy Tab S Original Android Development] b3ltazar:
Sorry about that i probably should of refreshed the page. Kernel works great happy i can use viper4android again. Glad you decided to give public releases for the t700 another shot....will report any issues but I doubt there will be any:cyclops:
[Galaxy Tab S Original Android Development] UpInTheAir:
Great :)

Just have the usual BUG in Synapse GPU QoS section. SSeekbar has failed: . Same as in KK kernel, nothing to worry, will disappear if GPU 100 MHz is used and Synapse restarted (close/open).
[Galaxy Tab S Original Android Development] pooya_30:
Hi guys!

sorry if i am a noob!

after flashing the kernel on t705 by TWR my device freez on galaxy tab logo.

i did a factory reset before flashing and wiped cash and dalvik after flash but still i get this.

thanks.
[Galaxy Tab S Original Android Development] rookie12:
Did you follow the instructions?
[Galaxy Tab S Original Android Development] pooya_30:
thanks for the reply.

Here is what i did

1- rooted

2- Install Synapse

3- installing Kernel by TWRP

4- wiping cach and dalvik

after these the tablet freez/Bootloop on galaxy tab logo.
[Galaxy Tab S Original Android Development] UpInTheAir:
I assume your device meets the requirements section ?

Lollipop installed ? Ensure you flash the T705 and not T700 kernel ?

What is your ROM version ?

Ensure you download is not corrupted (MD5 hash check) or re-download it.

What custom recovery are you using ? Try a different recovery ? I'm currently still on TWRP official v2.8.6.2 for SM-T705

The Installation Instructions don't call for wiping anything in recovery :cyclops:
[Galaxy Tab S Original Android Development] pooya_30:
Thanks you first!

1- i believe my device has the requirments , T705 - LTE - Exynos

yes lollipop 5.0.2 re downloaded kernel twice but same results.

Rom version : T705XXU1BoD5 (UK rom)

Custom recovery TWRP v2.8.6.2

may be i should re flash a new rom, waiting for your instructions.
[Galaxy Tab S Original Android Development] UpInTheAir:
Don't know, maybe update your ROM or re-flash existing ROM with Odin. Don't forget to back things up first !

EDIT: Could also try flashing boot.img with Rasher app
[Galaxy Tab S Original Android Development] maris__:
Just oberved a problem with Xposed. As I will be travelling today I tried to switch off wake on pressing the home button using the Wanam xposed module. This worked before with the stock kernel. This time I got a bootloop after rebooting my device. The message was that the system has been halted (or similar), resulting in a reboot after confirming this message. I am using XPOSED SDK21 modified for TW by arter97, version 2, and IronROM V2.0 by TkkG1994.

Best, maris
[Galaxy Tab S Original Android Development] UpInTheAir:
I have no idea because not using any custom ROM or xposed yet. Those xposed is just Alpha, so maybe not quite there for custom kernel tweaks.
[Galaxy Tab S Original Android Development] EiNESTEiNi:
Additionally, I have the mobile network signal bars showing in the status bar although I haven't got the SIM card inserted. Again: No 100% guarantee if it has to do with this Kernel.
[Galaxy Tab S Original Android Development] UpInTheAir:
Absolutely nothing to do with SkyHigh kernel. Why didn’t you test this yourself before posting?

It is same with stock. I think it might be possible to call emergency services without SIM inserted as I got a Thai language auto response message for mobile network.

Edit: If you haven't a SIM inserted into a T705 LTE or T805 LTE , best to enable Flight Mode so save battery so device doesn’t search for mobile network ;)
[Galaxy Tab S Original Android Development] ninspector:
Just changed several kernel flags for the purpose of chroot:

CONFIG_NAMESPACES=y

CONFIG_DEVTMPFS=y

CONFIG_DEVTMPFS_MOUNT=y

CONFIG_DRM=y

CONFIG_VT=y

CONFIG_CONSOLE_TRANSLATIONS=y

CONFIG_VT_CONSOLE=y

If I change the source code and I think that it is meaningful, I will start a pull request.
[Galaxy Tab S Original Android Development] UpInTheAir:
Just wanted to test before committing. Like to keep git clean and tidy. I do have a habit of reset hard HEAD sometimes....

EDIT: [MENTION=1349642]ninspector[/MENTION] : OK, added the defconfig changes and compiled with error.

Applied this patch https://lists.linaro.org/pipermail/linaro-dev/2011-June/004875.html and compile successfully :good:

Will check if it boots tomorrow.

I can PM you after then a release v1.1 to test (if you wish) ?

There are some nice ramdisk/Synapse changes too :)
[Galaxy Tab S Original Android Development] :
Ok just to inform. Everything fine here. Many many thanks UpInTheAir..

TabS 700

Rom TW detox 3.0, xposed installed

In Synapse i changed for now:

cpu [MENTION=1967609]2100[/MENTION]. Voltages everywhere - 50mv, except 2000 and 2100 +25mv

Gpu [MENTION=450896]667[/MENTION] (max)

Those was my stable settings in kitkat, so i tried for start in lolipop also. 2 hours now, running games etc, still stable no freeze. If it stay this way i will set full power settings as i had in kitkat also.

Cpu spy shows 250 mhz minimum frequency but if i remember well it is a bug of cpu spy (haven't change minimum frequency, it should be 500). I feel it needs some time more than original kernel to go to deep sleep, but working.

In original settings i don't feel much difference than original kernel, after overclock the difference is obvious..

At last i can overclock in lolipop! I was on step to go buck to kitkat only for this! :)

Thanks again UpInTheAir!! You can be a bit angry sometimes (i don't say that you don't have your reasons), but you are an excellent developer, and we don't have that many in tab s.. Your work is much appreciated.. :)
[Galaxy Tab S Original Android Development] UpInTheAir:
Good stuff, got another update in the next day or so. :fingers-crossed:

Have a few ideas to look into future too, but might take a look at my Note Edge kernel before that.

Just tired and frustrated at some users wasting my time having to needlessly repeat things. I just tell things straight, no need to "sugar coat" it. :rolleyes:

EDIT:

A7 LITTLE cores

100 = 200 (actual - Synapse)

150 = 300

200 = 400

250 = 500

300 = 600

350 = 700

400 = 800

450 = 900

500 = 1000

550 = 1100

600 = 1200

650 = 1300

700 = 1400 (not implemented)

750 = 1500 (not implemented)

A15 big cores

800 (actual - Synapse)

900

.

.

.

1900

2000

2100

As you can see, it's just the way Samsung use for their frequency and voltage table to easily calculate things.

@ T800/T805 users. Still waiting on T800/T805 boot.img from the firmware I requested a few pages back (you can search for the post). Seems there isn't much demand for it. I won't be chasing them, it's up to those that want to do ;)

Cheers,

UITA
[Galaxy Tab S Original Android Development] DUHAsianSKILLZ:
T800 boot.img coming up! Let me extract it on my bros pc and upload it in a bit since I had time to download it last night.
[Galaxy Tab S Original Android Development] EiNESTEiNi:
Thanks for the info.

I'm not a Pro user so I guess there was a bit of fear involved regarding flashing different Kernel just to find out.

Well anyways, now the airplane mode is activated and everything working just about perfectly.
[Galaxy Tab S Original Android Development] UpInTheAir:
Cheers, but that little rant in previous post was not directed at you. Those users should also be grateful / lucky to have you a willing contributor and tester for their device ! :good:

I will take a look tomorrow. I've had enough for today :)

Nice. :) You'll be a "pro" in no time. This is a development thread, and these things are what you expect to be "normal" and not "pro" ;)
[Galaxy Tab S Original Android Development] pinoypower:
Stuck on Galaxy Tab S logo with looping boot sound. Stock 5.0.2, rooted. Any idea?
[Galaxy Tab S Original Android Development] ninspector:
No problem, I am happy to test the new kernel source.

Which toolchain do you use to cross-compile? I compiled your kernel source with the flags stated before without any error (no patch required), my toolchain is v4.8.
[Galaxy Tab S Original Android Development] freaksamael:
Latest SM-T805 kernel attached. Extracted from UK T805XXU1BOD1/T805BTU1BOC1/T805XXU1BOD3/T805XXU1BOD1

UITA, many thanks for your time & support!
[Galaxy Tab S Original Android Development] UpInTheAir:
You have already posted in thread Q&A, no need to do it twice.....

Are you sure you aren't on IronROM, I remember you posting there.

What is your exact recovery and version number? Is it official or unofficial TWRP.?

One other user posted same earlier, I want to flash exact same firmware and recovery etc to try reproduce.

He never bothered to reply to the last suggestion and tell of the outcome...........

As per my published Makefile - 4.8 (and stated in OP)

Those flags enable quite a few others, so the maybe you did/didn't include those in defconfig.

Thanks, I'll see if it boots today, and if so, send you a test version by PM.

Thanks :)

Edit: just tried flash and stuck on boot screen. Will try and compile without those extra enabled flags and patch ...........

Edit2: It did eventually boot,................ after 2 minutes !

Cheers Mate :)
[Galaxy Tab S Original Android Development] DUHAsianSKILLZ:
My pc randomly started to work again. Anyway heres the latest boot.img from T800 T800XXU1BOE2/T800XAR1BOC5/XAR.

https://www.androidfilehost.com/?fid=24052804347759904 Thanks!
[Galaxy Tab S Original Android Development] pinoypower:
I posted here first but got a message on my post from admin saying that I should post it in Q&A, which I did, and I couldn't delete the original post.

Yep, flashed the stock UK rom as I was having high kernel usage with IronROM.

TWRP 2.8.6.2 for T705
[Galaxy Tab S Original Android Development] UpInTheAir:
You still didn't answer properly with info I needed...........

What is your ROM version . ie T705XXU1BOD5 (UK) ??

Is you TWRP official or unofficial one from XDA ?
[Galaxy Tab S Original Android Development] ninspector:
yes, CONFIG_VT=y is crucial, this flag makes booting process very laggy. i will try to figure out why tmr.
[Galaxy Tab S Original Android Development] UpInTheAir:
SM-T800 test kernel

DELETED, request fulfilled !!

Cheers,

UITA
[Galaxy Tab S Original Android Development] pinoypower:
You did not ask for the ROM info tho, I assumed you noticed my attached screen shot on my original post showing my software info, but yes it's the T705XXU1BOD5 (UK).

Yes it's the official twrp from xda.
[Galaxy Tab S Original Android Development] UpInTheAir:
Yep, sorry. Did miss it. Was probably in the middle of banging my head on the desk / keyboard :cyclops: :p

Anyway, probably your firmware version needs to be updated ROM and bootloader etc. Don't ask me which, I'm not going to go downloading all firmware releases just to test. I would suggest the latest available for any region.

I have added to Post #3 FAQ & HELP
[Galaxy Tab S Original Android Development] UpInTheAir:
v1.1 released

v1.1 update is released for SM-T700 WIFI and SM-T705 LTE devices.

NOTE: I have not personally tested the T700 kernel, as I don't have your device variant, so please read the Installation Instructions !!

If you have boot stuck on Samsung boot logo, suggest to read Post #3.

SM-T705 LTE users can clearly see in my attached screenshot my firmware version working well with SkyHigh kernel v1.1 and SELinux Permissive.

Don't forget to force stop & wipe Synapse data before flashing !!

Cheers :)

UITA
[Galaxy Tab S Original Android Development] UpInTheAir:
Op updated

OP UPDATED

Added Synapse Features to OP.

Most descriptions can be found within Synapse app or GOOGLE. :)
[Galaxy Tab S Original Android Development] DUHAsianSKILLZ:
No need to test :D I went through the hassle with odin and upgraded to OE2 this morning. I needed an upgrade anyways. Kernel is working!! For those having bootloops, you have to have a ROM on OE2 for T800. All smooth so far!

Screenshots!
[Galaxy Tab S Original Android Development] UpInTheAir:
So the "hassle" was worth it in the end :)

I'll compile and build some 10" SM-T800 WIFI & SM-T805 LTE v1.1 kernels tomorrow. ;)

Edit: and edit that request post from earlier on. Can't believe you had to do all the testing again, how lazy of many !

.
[Galaxy Tab S Original Android Development] :
V1.1 working fine here in t700 as was v1..

Thanks for the update!
[Galaxy Tab S Original Android Development] RoyBM:
Left everything default since I dont know too much about safe settings on the other stuff. Didnt overclock since my tab already seems to run hot.

Awesome battery life with this!!! Mainly what I was looking for. Great performance over stock also.

Thank you for SkyHigh!!!
[Galaxy Tab S Original Android Development] UpInTheAir:
For battery, could try the very very basics :

* disable Synapse apply on boot (menu in top RH corner) so if you have issues testing, then device can reboot easily *

1. CPU min freq = 200 MHz

2. GPU min freq = 100 MHz

3. GPU voltage 100 > 480 MHz -50 mV (start -25 mV first).

4. Power efficient work queue (PEWQ)= enabled (will reduce performance slightly)

5. CPU governor = on-demand (use with PEWQ)

6. sched_mc_power_savings = 2

7. GPU governor = battery

These are just some of the essy changes to try, best to test one thing at a time for stability, especially frequency and voltages ;)

Have fun :)
[Galaxy Tab S Original Android Development] DUHAsianSKILLZ:
I have the same exact settings except the voltages, (Don't want to mess with that) overall no problems so far and is working perfectly!
[Galaxy Tab S Original Android Development] UpInTheAir:
Will have v1.1 for both T800 / T805 in a while. Not sure what changes were made from the test version I sent you, I know SELinux is set permissive by default, the rest (if anything), can't remember..........
[Galaxy Tab S Original Android Development] UpInTheAir:
This boot.img is from very old firmware, Samsung is due to release newer, so we might need a newer ramdisk (when available).......

I will try build using the extracted ramdisk, but I can't guarantee which firmware (if any it will work) because my kernel sources are newer (E6) than the base firmware (ROM, boot-loader, modem etc). Users will just have to find out for themselves what works ;)
[Galaxy Tab S Original Android Development] maxq1:
best benchies i got so far in LP @v1.0...trying out UV on v1.1 now

thank you very much, OP! been following your work since the S3 days. mega thanks to you and andreilux! btw, some questions, if you will:

OC'ing to 2.1ghz doesn't seem to stick in my case. i mean, i could set it via synapse but when doing benchies or games, it seems anything over 1.9ghz doesn't seem to get used. i'm using system tuner and cpu spy to check. all kernel tweaking apps i have are disabled (or at least the functionality is disabled). doesn't seem to stick upon reboot as well. the rest of the settings are good though. maybe just me? i'm on detox. removed stericson busybox v1.23-2 (which worked too, btw) & used the kernel default, hoping to resolve this.

is DVFS on LP not a concern now like back in KK?
[Galaxy Tab S Original Android Development] rookie12:
What rom are you using?
[Galaxy Tab S Original Android Development] UpInTheAir:
Using OC CPU frequencies are pretty much useless during benchmark because thermal throttling is evoked quite early on and hence device never cools enough to reach those brief frequencies again. DVFS probably interferes too, I just can't check xposed (to disable it) on my device yet. I use stock odex for testing and stability.

I would suggest to disable COMPLETELY (or better remove ) any kernel tweaking apps etc as per installation instructions ..............

You can check time in state here : /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state

Everything "sticks" for me on reboot (including 2100 MHz), following my own instructions ;)
[Galaxy Tab S Original Android Development] ninspector:
1.1 works fine, but I cannot use split_boot to extract the ramdisk.
[Galaxy Tab S Original Android Development] UpInTheAir:
You'll have to find one that supports LZMA compression/decompression, I haven’t bothered looking because I only need to compress it into the boot.img. boot.img size needs to be kept under 8 MB for partition.
[Galaxy Tab S Original Android Development] UpInTheAir:
v1.1 T800 WIFI & T805 LTE released

v1.1 initial release for SM-T800 WIFI and SM-T805 LTE devices.

NOTE: I don't have your device variant, so I am not able to personally tested these, so please read the Installation Instructions !!

If you have boot stuck on Samsung boot logo, suggest to read Post #3.

T800 users - You probably require the latest firmware T800XXU1BOE2.

T805 users - Please also read THIS post

Don't forget to force stop & wipe Synapse data before flashing !!

Thanks to [MENTION=5978945]DUHAsianSKILLZ[/MENTION] to supplying the T800 ramdisk and testing

Thanks to [MENTION=938118]freaksamael[/MENTION] for the T805 ramdisk.

Cheers :)

UITA
[Galaxy Tab S Original Android Development] DUHAsianSKILLZ:
V1.1 working well and all good. Flashed in Twrp with no problems. Thanks!
[Galaxy Tab S Original Android Development] maxq1:
detox, like i indicated on my post :)

---------- Post added at 08:27 AM ---------- Previous post was at 08:09 AM ----------

reply in blue...same findings on v1.1
[Galaxy Tab S Original Android Development] UpInTheAir:
xposed is possible : My post HERE :

I won't bother replying about this again if you don't get rid of those CPU control apps like I suggested. For me, CPU OC control does work as intended when following my own advice/instructions .

EDIT: See attached screen-shot, I set to 2100 MHz very briefly :)
[Galaxy Tab S Original Android Development] maxq1:
^ fair enough. no probs here, man.

on xposed: i think i wasn't clear when i mentioned "app hasn't been updated yet for xposed LP". i meant wanam's DVFS disabler app. haven't tried wanam exposed (for LP) yet though as it has a DVFS disabler too.
