Firstly, I didn't mean to be harsh at all. If I sounded that way, I apologize to you.

Yes, Paragon reads my card. I experimenting with various roms, and noticed that ACPI rom mounts it only if it's formatted in NTFS.

So I was curious if you kernel is capable of mount an NTFS card *and* let me see it from pc in MTP mode. Like exFAT cards.

I know that exFAT maybe is more efficient, but it will more useful to me if I can mount properly more sdcards file systems. :)

I don't know if this is kernel related, or if it's possible at all. I just asked.

In any case: thank you, and keep up your great work. :good:

PS: Happy anniversary! ;)

You got to follow the instructions.....

1. wait a couple mins after boot for the CPU temp to settle. It will have throttled the A15 cores.

2. After that, make any change and apply. Just be patient after booting !! ;)
[Galaxy Tab S Original Android Development] UpInTheAir:
Ensure you have no other CPU control type apps installed

Ensure there are no init.d scripts installed in /etc/init.d folder (except ROM root script - if there)

Device settings > applications > Synapse > Force Close > wipe data

Remove any busybox in /system/xbin or system/bin

Flash SkyHigh kernel in TWRP

Reboot

Wait 2 mins for device to stabilize

Open Synapse and tap "understood" and APPLY.

Make some changes in Synapse > APPLY

Reboot

Wait 2 mins for device to stabilize

Open Synapse ............

I did some tests, running antutu with f2fs and ext4. Ext4 was faster.. I don't think tab s has anything to benefit from f2fs. I haven't the numbers right now but f2fs was definitely a bit slower. All other things the same.

I have a question. The kernel works pretty good but I have a feeling that my Tab S is charging VERY slow. When I say very, it takes like almost 7-8 hrs to charge completely. I dug into synapse a bit, but found a lot of sliders to change input current which was kinda confusing and I'm afraid to mess with it without knowing. So can you guys help me out with this? For the record, I use Anker 5 port 30W charger, in which it delivers 2.4 amps per port or 6 amps overall (I never use 5 ports simultaneously. When I charge my tab S, I use just a port so I can see that it's still slow. I use the Samsung USB cable that came with the tablet).

I used the 'Ampere' app to measure charging and the max it reached was 1300mA.
[Galaxy Tab S Original Android Development] rookie12:
I set it to max 3000 mah for very long and I dont have no problem i am charging with normsl Samsung charger
[Galaxy Tab S Original Android Development] EiNESTEiNi:
Nice to hear that things are rolling nicely.

It's definately worth waiting to get a Stable and fast kernel instead of a release that still needs quite a bit of work to be done. So take your time!
[Galaxy Tab S Original Android Development] UpInTheAir:
From a development point of view, incremental releases prove a better pointer to locating potential bugs with greater user feedback. With 300 + commits for one release could be a task to get right. Things will always require tweaking etc, but can only hope nothing major because I don't have the time to test everything. If something isn't quite right, would take a long time to track the culprit down..

My internet connection is intermittent and caused by the rain. So an all-stop right now :( ............. Hopefully working better later/tomorrow.
[Galaxy Tab S Original Android Development] ninspector:
May i ask you to put the source code on github after the inital release? Because i am a heavy chroot user, i need devtmpfs support, which seems not to be supported in your KK kernel releases.
[Galaxy Tab S Original Android Development] UpInTheAir:
Of course. All my kernels are GPL legal compliant and posted within the XDA rules. I choose github as a means of being transparent, easy to collaborate and keep track of changes etc. I could just upload a tarball, but that would be selfish to those I've cherry-pick and adapted from.

Essentially, this means that the source code must be made available for all Linux derived kernels to compile the exact kernel binary (zImage)

at time of release

. I have ALWAYS worked within the above framework, so there is no reason to expect anything less. If you find any member not compliant, you may request that member for the source be made available (for publicly released kernels) or contact a friendly Moderator as an intermediary. There are many not receptive to this though.....
[Galaxy Tab S Original Android Development] UpInTheAir:
I'm still "on the fence" whether or not to implement the Hotplug

from my KK kernel

. If any user can provide a compelling enough reason, I might to consider it. I just don't know.......

Anyway, T705 kernel v1.0 is in the latter stages before release. Expect it very soon :)
[Galaxy Tab S Original Android Development] UpInTheAir:
v1.0 released

SM-T705 kernel v1.0 is available for release.

Please read the installation instructions !!

EDIT: [MENTION=5978945]DUHAsianSKILLZ[/MENTION] , not sure from which builds you extracted those boot.img's ?

If T700 users wish the same, please provide the boot.img from PDA T700XXU1BOE5. You can download and extract from the full firmware package at sammobile or samsung-updates.

Cheers

[Galaxy Tab S Original Android Development] rookie12:
T700 will release soon?

And is the chance high to damage hardware with this kernel or is this 100% save that it wont damage anything?
[Galaxy Tab S Original Android Development] UpInTheAir:
This doesn't deserve an answer..............

After spending a couple days travelling and with jet lag, I just just spent 2 1/2 days straight porting this from my KK kernel (with additions). Please give me a break !! Read post above ...........

If you're worried about anything, don't bother flashing or modifying your device. FACT: User ignorance is the #1 cause of damaged device and data loss ................
[Galaxy Tab S Original Android Development] maris__:
Big thanks for the new kernel - running great on my T705. With the stock kernel, I was unable to install Viper4Android, with your kernel it works flawlessly after switching the SE kernel mode to permissive with Synapse.

Just as a note: after flashing the kernel, I needed to give in my wifi settings, as they were seemingly wiped.

Best, maris
[Galaxy Tab S Original Android Development] UpInTheAir:
Good to hear :)

Should not be wiped from one SkyHigh kernel to another. For example, if you flash SkyHigh over another Skyhigh kernel, settings won't be lost because settings are already saved with secure storage disabled. If you re-flash stock kernel, settings will be lost because secure storage is enabled and your settings were saved with it disabled.

Edit: I'll look at making Permissive default in the future (whilst keeping the Synapse switch Enforcing <> Permissive). The ramdisk is a little weird, and didn't work after a couple tries. Needed to move on this other things.
[Galaxy Tab S Original Android Development] ninspector:
Thanks for your effort, UpInTheAir! I have cloned your github source and compiled it with namespace and devtmpfs support, it works like a charm!

[Galaxy Tab S Original Android Development] ashyx:
If and when you decide to release your source code for the t805 model. I'd appreciate it if you could give me a heads up before adding hotplug so I can clone your repo first or at least make the first release without hotplug.

Personally I don't see much benefit to it.

Thanks.
[Galaxy Tab S Original Android Development] EiNESTEiNi:
Thanks for this!

Seems to work like a charm. Only initial testing done at this point though.

For some reason there was a bit of a problem going on when I enabled UKSM in Synapse. First the tablet was laggy as hell and after I switched the tablet off and connected it to charger the whole thing wasn't able to boot up. I did the hard reset thingy which led me to the choice of DL Mode or Vol Down (if I remember correctly) to reboot. After reboot the Synapse settings were pretty much in their initial (default) state. I'm not 100% sure if it indeed was the Memory -> UKSM setting in Synapse or not but I have a strong hinch of it. Dunno even if it has to do with this v. 1.0 Kernel or the Synapse app but thought to let You know.

Thank you for the release, it's been long awaited here. Besides the mentioned problem above everything has worked flawlessly.

My respect to the developer of the kernel!
[Galaxy Tab S Original Android Development] UpInTheAir:
The hotplug I used in KK had no reboot issues like other kernel. So obviously you never tried my kernel before. You can always remove something you don't like. I try and compile all kernels from same source, but first attempt for T800 failed.
[Galaxy Tab S Original Android Development] UpInTheAir:
If you wish, can you please send me your patches or link to where you found them. I could include it in further releases

Thanks, I'll take a look today (Sunday)

Don't know. My tablet has been going strong for the last 12 hours since I last flashed. UKSM has been enabled the whole time.
[Galaxy Tab S Original Android Development] ashyx:
I was using your kernel on kitkat and it was fine. So was Iron kernel on lollipop.

However it didn't like the F2FS file system, with hotplugging enabled it caused the tablet to freeze.
[Galaxy Tab S Original Android Development] UpInTheAir:
I believe you were talking about IronKernel here, not SkyHigh........ FS should have nothing to do with Hotplug
[Galaxy Tab S Original Android Development] DeathlessOne:
Can you let me know which options you changed? And, thanks!
[Galaxy Tab S Original Android Development] UpInTheAir:
As per attached screenshot. Providing your charging source is recognised as "AC Mains" and "Fast", then max SCREEN OFF is limited to the max output of charge source up to 2550 mAh. Stock max screen off is 1800 mAh.

Screen ON charge rate is limited to max stock 1200 mAh (from memory) and no control (doesn't appear to work).

Make adjustments, then connect charging source.

Using my Note 5 charger (3150 mAh max), have seen my "Current Now" at 2300+ (for about a second before it polls for new values) after opening Synapse to battery section so live values were visible, make adjustments, plug in charger, turn off screen, charge a bit, quickly turn on screen......

Of course, you will not have max charge rate to 100% because of the "top off" current.

I'm sure I've covered most of this in thread or its Q&A section though ......

[Galaxy Tab S Original Android Development] UpInTheAir:
You only need to look at my release posts for my setup.......... I always use rooted stock and NO Xposed

I believe to have previously said that you need to have "Synapse boot completed" otherwise settings won't stick no matter how long you wait......

Either your device is unstable with 2100 MHz or "Synapse boot cancelled".

Not all device SoC are the same. You need to live with it or use alternative means because as far as I'm concerned, there is nothing to "fix" here.

3. Post your full firmware information and details of device setup, mods or tweaks etc.

4. There is a reason the kernel.zip is meant to be flashed via custom recovery and not as boot.img

[Galaxy Tab S Original Android Development] schiphol:
Hi,

Thanks for this Kernel, seems to be giving me moderately better battery life when screen is on compared to stock. I was hoping it would also fix some of the kernel wakelocks stock is suffering from, but it seems to be exactly the same. I am sure you are aware and maybe you can optimize that some more in the future.

Importantly tho and this is very different from my A5 (and old Nexus 4 for that matter), this tablet refuses to be power efficient on music playback (screen off) through the headset. The wakelock is there all the time and it just refuses to sleep and you can see it drain about 0.5% per 5 mins (awful!). Music playback refers to standard mp3 file from the internal SD using stock music player.

Maybe this is a dumb question but is that something that can be improved on the kernel-side through updates or synapse settings. If anything, would an obviously knowledgeable developer like you maybe able to explain why this device with this exynos chip keeps the CPU at 250mhz on simple mp3 playback?

Thanks!
[Galaxy Tab S Original Android Development] rookie12:
[MENTION=3511708]UpInTheAir[/MENTION] are still planning to update this awesome project? Just worried because you havent updated it in a while or give us a heads up when?
[Galaxy Tab S Original Android Development] UpInTheAir:
The cores won't hotplug

if a task is scheduled. The music player will keep wakelock otherwise the device would sleep. In default state, the kernel has either 4 LITTLE or 4 big cores "on" at anyone one time. You can play with the CPU MULTICORE settings in Synapse and this will force hotplug cores when screen on/off states. 250 MHz is actually 500 MHz, which explanation in Post #3 (I think)

I'm still using the tab and there are a couple things still not quite right. The experimental RAM tweaks needs a look at and also adjustments to various Synapse controls such as restore/backup.

As you know, I don't take a "shotgun" approach to what I commit to source, and don't update just to make things appear good or for the sake of it.

For the time being, I intend to continue with updates only if warranted and/or I have time.

I was away for around 5 weeks and back home only 2. As you would understand, I concentrated just on my new Note 5 SkyHigh kernel :) But now I'm away again, and for an undefined extended period.

Hi again and thanks for replying. I understand that other apps may indicate incorrect CPU values but I am not really concerned wit that, all I want is my phone to go to sleep when playing music (as any other cheap android phones I have owned did!)

Based on your recommendation I have played around with the CPU MULTICORE settings but I still cannot get it to work, the tablet refuses to sleep when playing music in screen off state regardless of music player and settings I have tried.

Can you maybe suggest some settings to try in the Synapse, as I am really not sure what some of the settings actually do and not all available tweaks and settings are properly (elaborately) explained in your posts on the first page.

Really hope you can help, thanks!

Headphone amplification

but when I open synapse in the audio section after SP equalizer settings .. I can't find Headphone amplification

only HP equalizer settings.

Is Headphone amplification = HP equalizer settings ?
[Galaxy Tab S Original Android Development] maxq1:
don't think so. HP equalizer settings is for tweaking...well, your device's built-in headphone equalizer settings. i've amp'd my T700's speaker volume by adjusting the main speaker volume, so if you wanna amp the headphone volume i'm guessing earpiece volume is where it's at.

Been supporting the Note 5 and it's variants quite a lot. So decided to take a peek at Samsung OSRC to see if they have released any source update for our Tab. Surprise surprise............ NONE since August !!

Appears that the Tab-S is getting left behind now and I won't expect much more from Samsung. We will be lucky to get 5.1.1, but surely never 6.0. There are just to many devices for them to support and why would they update the Tab-S (will be 2 yo soon enough) when they probably encourage users (or potential users) to by the latest they have available............... all about $$$

Anyway. there are a couple fixes needed for this kernel, but I just lack the motivation for it ...............
