R4_v2.5.0 kernel runs like a charm! "SYNAPSE BOOT CANCELLED" issue solved following instr of post 3, same for "SSeekbBar has failed".

As usual, much appreciated - keep up the good work! Thanks.

How long takes you to download that file? I can upload it for you in 10 hours or so if you want and if you don't already have it
[Galaxy Tab S Original Android Development] UpInTheAir:
How long is not the point .................

I only need the 7 MB boot.img from it. I'm not going to DL 1.5 GB myself. If users wish for an updated kernel for their device, they must make the

contribute

themselves. I won't go chasing it for device I can test or use.

I haven't updated the T700 kernel either, so the kernel mustn't be that high in demand, or, too many leechers not willing to give something back to help themselves. I do enough for devices I don't use, plus I have other personal/professional priorities and also other device to support too.

I just built a basic ROM for my N915 and with over 300 DL, not ONE thanks. Nice encouragement (not) !

Just a word of warning, once LP kernel source is released for our devices, there will be a new single thread covering all SkyHigh TW kernels. These TW kernels will not be included in any 3rd party ROM so kernel related tracking and issues can stay with the kernel. I even get users complaining about CM kernel (which I currently have nothing to do with) posting in this TW thread ! .............
[Galaxy Tab S Original Android Development] Tkkg1994:
I know what you are talking about. For example I can see how many peoples that were looking at my screenshots of the rom and how many are reading the thread.

20'000 viewed the screenshots, 15 thanks. Great I know :/

So you mean no longer add your kernel as default kernel when lollipop is out?

The boot.img for you will be there tomorrow, don't worry!

Users sometimes don't care about things. They just think, the devs make everything and I don't have to do anything else, except from reporting bugs ...

Have a nice day!
[Galaxy Tab S Original Android Development] UpInTheAir:
Not just you, but anyone. Rules have to apply same to all.

Hey, I don't worry ;) I have other things to do and more important things to worry about :)
[Galaxy Tab S Original Android Development] Tkkg1994:
Just want to help you pal! :)

You kernel always works great. So I'm a bit disappointed that I have to use stock kernel in lollipop again :(
[Galaxy Tab S Original Android Development] UpInTheAir:
Having my SkyHigh TW kernel in 3rd party ROMs by default doesn't actually do anything to help me or kernel development in my own threads.

the latest version breaks Private mode. Can you fix it ?
[Galaxy Tab S Original Android Development] j1gga84:
No problems here on T805 as usual, good job :good:

regards
[Galaxy Tab S Original Android Development] Tkkg1994:
It isn't caused by the kernel... it is because you have root. Download Xposed Installer and set up the framework. Than install wanam xposed. After setting up that, go to security and enable private mode. You have to enable that BEFORE trying to enter in the private mode the first time. Otherwise it wont work anymore...
[Galaxy Tab S Original Android Development] UpInTheAir:
Hey. Firsts signs of trouble, let's just randomly blame the kernel and expect a fix. :rolleyes:

Some users are on ignore, because of various reasons and not following development thread protocols. Hence me not replying because the post isn't visible.

Thanks for helping out. :)
[Galaxy Tab S Original Android Development] sku||:
ok, i reflashed the stock rom, then i flashed cf auto root with odin, and you know what, i still can use private mode :D

Would you consider adding the ROW io scheduler? Considering it's intended for solid state
[Galaxy Tab S Original Android Development] UpInTheAir:
I have compiled it in the past for 5420, but reset my git (removed commit and history). There are a lot of block patches etc required first to get it compile, and I just wasn't happy with it. Might take a look in future again though, no promises.
[Galaxy Tab S Original Android Development] Zootopia:
This is where the magic starts to happen in what concerns the TAB S lifespan... long live UpInTheAir's kernel !

Running smooth and fast here with my T800.

[Galaxy Tab S Original Android Development] lisboapcs:
Warning!!!

With all respect for the SkyHigh kernel creator but I almost had my tablet bricked when I installed this update. I was about to play a very simple game called Jewels when it reboot to "sdcard mode" and was stuck there till I let the battery drained empty and did factory reset. My rom is the IRONROM 1.9.
[Galaxy Tab S Original Android Development] DUHAsianSKILLZ:
SDCard mode isnt related to the kernel. For some reasons samsung devices do that which I am unsure why. What most people do is let the battery drain and factory reset like you did.
[Galaxy Tab S Original Android Development] ramiss:
Your device isn't bricked as long as you can get into download mode. It's pretty impossible to truly "brick" a device these days.

Next time ry holding down Power and Home until the device hard resets.
[Galaxy Tab S Original Android Development] lisboapcs:
Thanks!
[Galaxy Tab S Original Android Development] JUNEBUG-1:

[Galaxy Tab S Original Android Development] artoni:
I can't set the tab to keep the overclock nether to 2 GHz nor to 1,9 GHz, it automatically switches back to 1,8 when I open synapse again. Does someone know why it doesn't work? It used to work one month ago

[Galaxy Tab S Original Android Development] artoni:
Yes of course. Sometimes even when I click on apply it switches back immediately..
[Galaxy Tab S Original Android Development] Mokum020:
Did you try to disable DVFS, it's in Wanam Xposed/advanced.

Otherwise there is a seperate Xposed module for it you can try:

Reinstalled the Rom and kernel and now it works
[Galaxy Tab S Original Android Development] wbedard:
I've been running your kernel on my T800 for almost a week now with almost no discernible issues at all. I did have to discover that I needed to activate Android logging in the Synapse app in order to view logcat info but that was it. Great job on the new release and keep up the good work... it's greatly appreciated!

[Galaxy Tab S Original Android Development] vibecatalin:

[Galaxy Tab S Original Android Development] RichPLS:
Working great on my sm-t700. Thanks again, UItA!
[Galaxy Tab S Original Android Development] Tkkg1994:
Just a small question. Am I the only one getting problems on 2.1 GHz? Sometimes reboots itsself. For me 2.0 GHz is much better!
[Galaxy Tab S Original Android Development] vibecatalin:
Me too, but as far I understand you have to tweak a little bit the voltage CPU to get stable at 2.1 Ghz.

I'm using 2.0 Ghz with 600Mhz at GPU.

What other settings you guys applied with Synaps?
[Galaxy Tab S Original Android Development] Mokum020:
Mine runs fine at 2100Mhz without voltage tweaks even with ASV being 2.

CPU: 200-2100Mhz, GOV: Interactive

GPU: 100-667Mhz, Mali: Demand, GOV: Performance

KSM: Enable

Also upped the AC/Mains charging to 2000mA, rest is default.
[Galaxy Tab S Original Android Development] UpInTheAir:
It just uses slightly higher default voltage (determined by ASV) for any given frequency to maintain device stability. Downside will obviously be higher battery drain, and operating temps invoking thermal throttle earlier than devices with higher ASV.

Of course, some users would never know or able to tell the difference. Just don't get too obsessed over it and enjoy ;)
[Galaxy Tab S Original Android Development] UpInTheAir:
Try increase the 2100 MHz voltage. I would suggest just a little bit at a time and test for a while, once happy, increase again +6.25 mV just to ensure long-term stability.

If your default synapse voltage is already at max 1362.5 mV well that's it, as I cap it to mirror the asv voltage table. ;)
[Galaxy Tab S Original Android Development] UpInTheAir:
Been busy with work and away, back home and starting to play with the kernel again. Not sure what the end result will be yet. ;) Hopefully a KK update to give "flash-aholics" something to do. .. ;)

Just hoping LP kernel source will be released in a timely manner though :)
[Galaxy Tab S Original Android Development] Zootopia:
So nice to see you back here again :)

V2.9 is running without problems on T-805 LTE :good:

Will test it further :)

btw. have you considered to built your kernel with Linaro Toolchain 4.9.3?

Would this have any benefits?

thanks for update :)

Regards
[Galaxy Tab S Original Android Development] UpInTheAir:
I don't really know if there will be any added benefits or placebo.

Actually I did start to build the latest release with 4.9.3, but I lost interest in tracking down a compile error (I didn't want "hide" it in Makefile).

What I do know, is that 4.7 is stable, fast and efficient enough.

I'm just having a little "fun" before official LP on my Note Edge and T705 :)
[Galaxy Tab S Original Android Development] Tkkg1994:
What is interesting for me: Why didn't you update the kernel to version 3.4.106?

Then you got all security patches and so on. :)
[Galaxy Tab S Original Android Development] UpInTheAir:
1. 99 % are nothing to do with security. .. (where did you source that term?? )

2. Important updates are in OEM source updates.

3. Well over half (maybe 90%) are nothing to do with files that are actually compiled.

4. It takes a lot of effort and time for possible little gain

5. I'm more concerned with optional tweaks and a usable kernel (lots in synapse for the power user)

6. No point in starting when LP is close by. Waste of time. Refer above points. Maybe I will for LP, maybe not.
[Galaxy Tab S Original Android Development] Tkkg1994:
1. Sorry maybe I wrote it a little bit false.

2. They put out patches that are fixing problems (open leaks) or stuff that makes your device slower.

3. That simply isn't true if you check my github then you can see what was patched.

4. Yes it takes a lot of time. But then I am sure to give my users one of the best experience out there :)

5. STweaks, synapse is kind of buggy :/

6. Your decision :)
[Galaxy Tab S Original Android Development] UpInTheAir:
Your first post make it seem that because I don't bother to update to Linux mainstream that my kernel is insecure. What a load of garbage. I noticed you had used that word "security" in your kernel thread OP.....

You think that because I haven't committed to github that I've never applied any patches. There is so many patches unrelated code to what's actually compiled.

If these patches were critical to security or performance, OEM would apply them during each incremental updates.. They don't.

Some things, even in this kernel could be placebo, or provide such minimal benefits (compared to time expended).

Please tell me what is so buggy (other than mentioned in Post #3) about my synapse implementation?

Is down to the kernel developer to implement the code and user to follow instructions. Is rarely the fault of the app itself. Same goes for your STweaks, is up to you to implement things properly, not the app. If you find it buggy, then it's up to you to fix your implementation, don't blame the app! !

Of course is my decision, I gave valid reasons why. ... as I said, maybe when we have LP source. At the moment, I'd rather not expend the effort for 100 patches for near outdated kernel. It's my time.
[Galaxy Tab S Original Android Development] Tkkg1994:
It was also my time. But I think you don't want to update to later versions anyway. As you also not use the latest version of the linaro toolchain. But why you shouldn't?

A friend of the developer of minecraft (hopefully you know what this is) told me always to use the latest version of compilors or kernel and so on. I think I better follow his suggestion. I also think that it is good we haven't got the same opinion at all.

You say, the linux patches aren't applied to stuff that we actually use? Why after two or four patches, I get some compiling errors? Because it patched some related stuff that is used for OUR kernel.

About synapse: I just know from the Galaxy S4 forum, that three devs switched from stweaks to synapse and then back to sTweaks again. Because they said, synapse is to unstable for them and not as good as stweaks is (at the moment).

After all: I just wanted to ask you this simply question about why you haven't done it and now I have my answer. I have my reason to do it, you too. I just invested about 8hours to patch the LL kernel to 3.4.106 (for the galaxy s4).

I hope you can understand my point of view, I can understand yours too!

Edit: You also spoke about the security I wrote. I meant, if a leak appears in the kernel source (you know towelroot?) then it will 100% (!) be fixed by a kernel patch from linux. They also make stuff more simplier, add new lines that make our device more efficient and fluid, because they found out a better way to manage that all (as they maybe found a year before).

Linux 3.4.39 is now nearly two years old! Maybe 1 and a half but that is a lot of time. Things are changing...
