If you can help me to learn how to decompress/disassemble Samsung's boot.img, I could try to make some recovery image.
[Galaxy Tab S Original Android Development] UpInTheAir:
There are many guides about for this. recovery.img is same principle.

Sorry, just don't have time to look into the recovery, let alone teach anyone.

I'm preparing to head away for about a month, so this kernel development will be suspended.
[Galaxy Tab S Original Android Development] suzook:
You sure you couldn't whip us 10.5 owner$ $omething??$$$
[Galaxy Tab S Original Android Development] UpInTheAir:
There's no whipping up anything, AlI takes a lot of time, which I don't have. I don't do anything for $$ but share where able, capable and or time permitting.

Have managed to get UMS (USB Mass Storage) working and control in Synapse. Just a couple issues with selecting MTP in Synapse will cause device reboot. Selecting back to MTP through ROM is no problem. Maybe I'll just leave out the MTP option for now so I can release before I go away. Wait and see.
[Galaxy Tab S Original Android Development] mitchellvii:
Are you noticing a performance increase running your kernel?
[Galaxy Tab S Original Android Development] jball:
Your pretty snappy man.you must have your build environment where it needs to be to allow for kernel building witch is the same environment to build recoveries. We realize your busy with life but you had to expect people to ask for certain things . normally it's root/recovery/rom.now I've only been ready/researching and not even close to achieving what you can do so don't take offense
[Galaxy Tab S Original Android Development] UpInTheAir:
There is no offense, but nothing to do with, and not contributing to this kernel development..... If you wish recovery, contact the TWRP team or Philz

I haven't played around to much with benchmark, so can't really comment too much on that. I personally aren't OC CPU or GPU right now. Benchmark just causes thermal throttle and inconsistent scores unless device is left to cool properly.

I do believe TW launcher is less "choppy" when scrolling. I leave animation speed as it is (haven't even checked if we have the option) and stick with the stock launcher, i like it. :)

How's performance guys. I'm stock and I get these annoying lags /choppiness atm in the launcher (for example opening an app, pressing home, waiting for keyboard to come up after I choose a text field). Also chrome performance is poor. Has this kernel solved some of that (over clocked and set to interactive perhaps?)

Thanks!
[Galaxy Tab S Original Android Development] UpInTheAir:
There is a recent firmware update that has been reported to help some. You may be able to OTA update or download from sammobile or samsung-updates.

I don't use Chrome, so no comment there.

I also don't see the need to OC, but it might help, depending on individual circumstances.

Scheduler is stock and default interactive.

Edit: Before I updated, I did notice what I previewed a some improved general UI in TouchWiz using this kernel defaults.
[Galaxy Tab S Original Android Development] 12MaNy:
I'll let you know when I'm able to flash it.

Stereo speakers

Hi,

In my tab s 8.4 wifi, with this kernel and CM11 variant, i have noticed that one speaker sounds a lot more than the other speaker.

Try stereo test in youtube or any other test and you will notice the big difference.

In stock kernel both speakers sounds well.

Anybody else has the same issue?.

In earphones sound is good. I think that is internal speakers issue with this kernel.

Thanks.
[Galaxy Tab S Original Android Development] danny19901:
Download viper or something and try alter but I didn't notice a problem also using CM version of this kernel with T700 CM11 and its amazing no issues even though I have T705

TAPATALKED WITH MY TAB S 8.4
[Galaxy Tab S Original Android Development] katobest:
But, this kernel has support for viper4android?.

I don't know so much about sound adjusting in android, but, i have tried to flash this kernel more than 5 times (stock->Skyhigh->skyhigh CM ->Stock->skyhigh->cm...etc..) and allways get lower sound in left speaker when i use skyhigh.

I think that is a bad sound balance configuration that i have only with skyhigh kernel.
[Galaxy Tab S Original Android Development] danny19901:
It should support viper or try synapse app I think you can modify audio with that

TAPATALKED WITH MY TAB S 8.4
[Galaxy Tab S Original Android Development] IcedCube:
Just reporting in here, flashed the kernel on my T705 and it feels snappier... somewhat. :D
[Galaxy Tab S Original Android Development] UpInTheAir:
Don't OC the CPU or UV etc, clear Synapse data as posted

I don't use his kernel ..........

Not kernel releated

It does work properly, and please stop spamming the thread about it. If you wish to use a lower (edit: min) autobrightness value, please contact your ROM dev.......

This thread is TW kernel and there are no issues

Nothing to do with kernel, contact your ROM dev

Nice to hear :)
[Galaxy Tab S Original Android Development] pibach:
Autobrightness on t705 is too low in the dark and too lit under light. So it needs frequent manual interaction. Not a big deal, but if there's a fix, that would be nice. Isn't it kernel related?
[Galaxy Tab S Original Android Development] UpInTheAir:
Personal opinion. In my opinion it doesn't need "fixing".

In older firmware you could change the values within the framework-res or System.UI (can't remember, too long ago), so contact your ROM Dev on this subject or use a app. Please let this be the end of the matter in this kernel thread, because I'm not going to touch the kernel drivers or play with the ROM. Thanks.
[Galaxy Tab S Original Android Development] danny19901:
Sorry to bother you but is 2.1GHZ the max reachable clock speed of Tab S ? Pretty amazing kernel
[Galaxy Tab S Original Android Development] UpInTheAir:
Probably not, but for most devices the max limit of stability is L4 2000 MHz or L3 2100 MHz.

https://github.com/UpInTheAir/SM-T...4b0728b/drivers/cpufreq/exynos5420-cpufreq.c

The A15 frequency table max frequency is L0 = 2400 MHz, but increasing above L3 is a waste of time due to the stated instability. To maintain stability, a voltage increase is required (if device can handle it) > excessive heat > thermal throttling > decreased performance.

So that's why I limited the max OC to L3 ;)

The GPU can handle (on my device) much more OC, UV than CPU. I can use -50 mV @ 533 MHz without issue, but I don't OC unless playing around or tweaking/testing. :)
[Galaxy Tab S Original Android Development] pibach:
I am runnig Big Cores at 2GHz and UV all -50mV. Little Cores on -100mV. GPU -50mV (but seemingly could handle -100mV as well).

Though I seldomly run into a freeze. The problem is to figure wether it is application related or due to the undervolting.
[Galaxy Tab S Original Android Development] UpInTheAir:
More than likely your UV.

Break down your troubleshooting. Try with UV just one thing and work from there. ie. GPU, big cores, little cores. .... narrow it down.
[Galaxy Tab S Original Android Development] fedecape:
Call me crazy, but this kernel + a Titanium backup de bloat session have significantly increased both my battery life and performance. (T700)

Thank you Up in the Air!
[Galaxy Tab S Original Android Development] gggg:
I absolutely agree wirh you regarding T705. Maybe our latest european versions (mine is from Oct.) differ from the one UITA uses. I had the low autobrightness prob. on a german, austrian and italian sm-T705 (= on all I had in my hands) . What I have found out is, that the light sensor used in SMT-705 LTE differs completly from others....

Anyway I am very happy that we have SkyHigh and still hope that UITA will overthink his decission regarding further developping for XDA/us ;)
[Galaxy Tab S Original Android Development] Stupid1337deer:
Yes I was C:
[Galaxy Tab S Original Android Development] MZWiZard:
Thank you very much for this wonderful kernel! I've used it for a month and no problems! Though I wish for the opportunity to set the big cores to like 2.4GHz? But maybe that's too high?

Anyway I'm satisfied. ☺
[Galaxy Tab S Original Android Development] UpInTheAir:
I've posted before that's is a waste of time because it's not stable (2000-2100 is max for majority of devices). Even if i allowed higher max voltage to help maintain stability, device would thermal throttle easily. I would know, because i tested it ;)

I also decreased the GPU max OC from 733 > 677 MHz (although stable) due to this. 733 was "just for fun". :)
[Galaxy Tab S Original Android Development] MZWiZard:
I know about the throttling issues, and indeed, it would primarily be for fun. However, I have modified my t705 with a copper heat spreader inside because of the thermal issues. This has brought a temperature decrease of around 20 degrees. That's why I'm kind of eager to try up it even more :good:
[Galaxy Tab S Original Android Development] UpInTheAir:
Sorry. I don't do user personal build unless for debugging purposes.
[Galaxy Tab S Original Android Development] MZWiZard:
Oh it's OK, then :)
[Galaxy Tab S Original Android Development] NickosD:
this kernel works for both qualcomm and exynos devices?
[Galaxy Tab S Original Android Development] UpInTheAir:

Kernel update

STARTED WORKING ON A KERNEL UPDATE

I REQUIRE T700 WIFI T700XXU1ANJ4 stock boot.img (so I can extract the ramdisk).

You can find the full firmware package at samsung-updates.com or sammobile.com.

Can someone please post the boot.img for me? Otherwise your device model will "feel no love" :) Got it now, thanks.

Update will take time, as personal commitments will be priority. Please be patient as I will also need to make changes and a bit of testing on my own T705 device first ;)

Thanks

[MENTION=3511708]UpInTheAir[/MENTION] tried to download firmware but Sammobile server seems to be down. Will try again tonight when I get home from work.

PM with the download link was sent.

Many thanks for your time & support for us!
[Galaxy Tab S Original Android Development] UpInTheAir:
OK, both T700 & T705 kernels are ready to UL, but XDA server is having issues. I wish to keep the project in one place and will wait until fixed, so will keep trying.

In the mean time, change-log etc have all been updated. Had to temp remove some features until I can sort them out.

'm going to "give myself an uppercut". I just patched to ANJ2 and didn't see the ANJ5 for T705 ......... Downloading to diff now !

Wow, thanks so much! Everything's fine, running your kernel on my T705 LTE with interactive/bfq, 200 - 1900 Mhz.

With best regards, maris
[Galaxy Tab S Original Android Development] TheGoD:
Ok, I didn't used it really much yet, but it seems great. Way smoother than the last build this far.

Edit: Using the T700 kernel :)
[Galaxy Tab S Original Android Development] UpInTheAir:
Just wish i can get the USB storage options sorted. One problem is the USB cable end it think is a bit dodgy. Don't know why it doesn't work same as old kernel..... maybe take another look tomorrow.
[Galaxy Tab S Original Android Development] palaiouras:
Been using the latest version. So far so good
[Galaxy Tab S Original Android Development] salvopetrucci:
How can I set battery in synapse in order to charging via USB with my pc?
[Galaxy Tab S Original Android Development] UpInTheAir:
There is nothing to set. Just connect via USB cable.

Standard USB Downstream Port max charge rate is always limited by the max source output. PC USB 2.0 is generally limited to ~475 mA max output, you can't make magic happen or expect your device charge level to increase whilst in use.
[Galaxy Tab S Original Android Development] slackerz_86:
V2.0.0 actually breaks led flash when taking photos for myself.. N in order to have it back,have to clear cache and dalvik in recovery.

T705
[Galaxy Tab S Original Android Development] senel:
2.0.0 works so far so good on SM-T700. I can also play Xcom without crashing, awesome!
[Galaxy Tab S Original Android Development] interfreak:
Quick question - apologies if this has already been answered.

Can this kernel be used with CM11?
[Galaxy Tab S Original Android Development] DUHAsianSKILLZ:
Most likely no. Check the requirements. It saids touchwiz 4.4.2 kitkat as cm11 is 4.4.4 with no touchwiz
[Galaxy Tab S Original Android Development] interfreak:
Thanks. :)
[Galaxy Tab S Original Android Development] UpInTheAir:
Doesn't "break" anything on my stock T705XXU1ANJ3 firmware.
[Galaxy Tab S Original Android Development] slackerz_86:
Well, for me atleast it does. And i am using 1.9.1 back. :(
[Galaxy Tab S Original Android Development] UpInTheAir:
Not kernel related as user can upgrade the firmware. :)

If you are using a custom ROM, contact your ROM dev for assistance or check if there's a new release using a newer stock base.

If you can't be bothered to post exact details to reproduce, current firmware details and device model etc, aren't welcome to post in this Development thread. That's spamming and doesn't help yourself or anyone else. ;) But as i said, please refer to comments above.
[Galaxy Tab S Original Android Development] Stupid1337deer:
I have an issue with my SM-T700!! I have DVFS disabler but I never got anything to do with resetting Synapse app all globally . Ive tried but i dont see where i go to do this.

with the new version Synapse just crashes upon startup. it crashes a fraction of a second after you tap the app open
[Galaxy Tab S Original Android Development] UpInTheAir:
Self induced error :p

The RESET ALL GLOBALLY is within the Synapse menu BEFORE flashing ............

Open Synapse & Tap (top RH corner)

:

Square box

3 vertical dots

select all globally

back arrow

Apply

Might help too

Go to device settings > applications......... > Synapse > force stop and wipe data/cache

wipe dalvik-cache and Cache in recovery (if needed)

Reboot

Try again
[Galaxy Tab S Original Android Development] Stupid1337deer:
bug!!

I just updated to the new kernel after coming from the old. Whenever I open the google search app, it crashes with "app unresponsive" or whatever. What should I do?
[Galaxy Tab S Original Android Development] UpInTheAir:
Why has this got to do with kernel?

I would suggest to force stop app (wipe app data/cache) and then wipe cache and dalvik in recovery (method as above).

If you continue to have issues, Please post in the appropriate thread and or contact your ROM Dev or manually update to the latest firmware via Odin.

I only build and test with the latest stock ROM available for my device model at time of kernel release.
[Galaxy Tab S Original Android Development] TheGoD:
No problems with flash on camera, Google search our anything else over here.
[Galaxy Tab S Original Android Development] stoney73:
Thinking of flashing the kernel, will it help with battery life on the t705?
[Galaxy Tab S Original Android Development] IcedCube:
UpInTheAir, could you please tell me what's different between the T700 and T705 kernels? Is it the LTE driver or some other things?
[Galaxy Tab S Original Android Development] UpInTheAir:
Try for yourself and tweak to your liking.

Without checking the source defconfig for exact answer....

modem driver and ramdisk. Other modules/drivers are same.
[Galaxy Tab S Original Android Development] pibach:
Didn't do scientific testing. But roughly I got a 10-15% increase in battery runtime, mainly because of undervolting.

It comes at the cost, however, that you never know whether a crash is caused by some app or by the undervolting.
[Galaxy Tab S Original Android Development] Stupid1337deer:
I am on stock rom. The issue only occured after I updated. So I assumed it would have something to do with it. That is all.
[Galaxy Tab S Original Android Development] UpInTheAir:
So, did you do as suggested or not? Without even bothering to say so, and instead bother to justify, you are ignored from now on. I'm not wasting my time anymore.

I do not have any issues and non other reported from many users.

Can only assume GUI. ....

I'm going to punch out a basic ROM in the next day or so for T705XXU1ANJ3 (what i use). Edit: Aroma takes a while to set up, and test properly, apart from that, my connection is so slow and unstable (N915S ROM took over a week to upload!).

No bells and whistles, just Aroma debloater and the usual. I don't have time and motivation for feature request.
[Galaxy Tab S Original Android Development] Tomv5314:
Will you do a version for the SM-T800? Hopefully:fingers-crossed:
[Galaxy Tab S Original Android Development] UpInTheAir:
No. Just my own device model. The firmware is just for T705 and is what i use.
[Galaxy Tab S Original Android Development] IcedCube:
Just a thought, and forgive me if it's already been asked, with Lollipop being made available for the T700, do you think you could cook a kernel for Lollipop and see if the eousphoros ROM works on our device? Since the LTE modem is the only difference, I think we'd have it booting somewhat.

I know this puts extra strain on you though. I would do it myself, but I'm too green with android kernel cooking (although I have built ARM kernels in the past for Linux distros, just not Android).
[Galaxy Tab S Original Android Development] UpInTheAir:
I don't have the time to spare to look at it. Got other device I'm playing with :)

I'll only build a kernel once official Samsung LP sources are released and only for TW.
[Galaxy Tab S Original Android Development] UpInTheAir:
Just working on v2.1 for 8.4 and 10.5 TW kernels.

CIFS bug fix and big synapse cleanup (code and redundant files), plus a couple additions and changes.

See if I can get the UMS storage mode working again. (Still yet to try).

NO ETA,

and NO, not doing any CM kernels (I have given permission to them to adapt my work, so go bother them ;) )
[Galaxy Tab S Original Android Development] UpInTheAir:
NEW kernel tonight.

Have compiled and built boot.img for 8.4 and 10.5 Exynos devices.

Out all day and evening, so no time yet to upload v2.1 and update Posts #1-3.

Runs fine till now on SM-T700. No OC or UV yet. [MENTION=3511708]UpInTheAir[/MENTION] Something specific to test on T700 variant?
[Galaxy Tab S Original Android Development] UpInTheAir:
Nothing specific. I can only assume all is good, i could easily make a mistake swapping files around with building 4 kernels at once.

Setting KNOX to NO_ACTION (and apply) should speed up synapse load on boot. Still recommend to disable Knox first (If not already removed from ROM), and then set to NO_ACTION for fast boot. The Knox apps should still be disabled/frozen. You can check with Titanium app

Had one System-Hang during stressing GFXBench which I still have to try to reproduce and provide log; also have to compare against stock.

Also yet have to test using OC.

so Chances become slim we get UMS back ever?

Already had that Setup.

Had stressed GFXBench once more - and this time it went all through!

Retried GFXBench using OC to 2.1Ghz max - but tablet resetted instantly. Have to rerun this soon and provide kmesg
