Not really interested in logs in any settings other than kernel default and only if using completely stock rooted ROM of the latest firmware (or my own ROM). I'm not going to waste time to debugging something i can't reproduce or debug other issue than kernel.

Edit: Just downloaded GFX bench and ran full test (took a while) and no issues. Running SkyHigh ROM and kernel defaults (GPU 177-480 -50MHz and CPU 200-1900)

Who knows about UMS, I don't. I have only one last thing to try. If it's not consistent, it's not included.

Just went to super Sammy ROM v2 full wipe and flashed latest sky high but WiFI won't obtain IP from my tether I have T705
[Galaxy Tab S Original Android Development] UpInTheAir:
WIFI and BT tethering works fine with SkyHigh ROM.

Please contact your ROM developer in the first instance, or update your firmware, thanks.

Edit: sorry, read your post again more closely. The word "from".....

Yes works for to, but from won't connect with security enabled tether, only open tether.

It's probably one of the setprop I use in the kernel int.rc .I'm sure there's something on the net somewhere. Maybe you want to take a look? And you can write into your build.prop or if doesn't work a script to set on boot. Just spending some time with my son, so this isn't even on the list ;)

After flashing the WIFI Kernel for my Samsung Galaxy Tab S 8.4 Wifi 16GB (SM-T700)

The tablet will not boot up.

I installed it using TWRP and everything looked fine untill it did the bootup animation and stopped at the text "Samsung".

Any ideas why this is happening?
[Galaxy Tab S Original Android Development] UpInTheAir:
Well, no actually. I flash many almost every day with only self-induced issue.

Can only guess what firmware version and ROM you're using.

Can only guess if you've read Post #3 Help & FAQ suggestions.

Can only guess if you've flashed the correct kernel.

Can only guess if you've done as above and re-download the kernel and flash again (after above).

Can only guess if you flash your backup kernel (part of installation instructions) from recovery (or stock kernel in download section).
[Galaxy Tab S Original Android Development] epicmoi44:
Well now I tried using the stock version and it works fine , I was just trying to give feedback.
[Galaxy Tab S Original Android Development] UpInTheAir:
You gave nothing defined as "feedback". What was given was a complaint with no useful information that would lead to others assisting YOU.

[Galaxy Tab S Original Android Development] UpInTheAir:
I think the kernel needs to be compiled with some config options enabled. I saw something somewhere for a Pxx kernel in XDA. Could be wrong though. Is not of interest to me, however, if you do the "groundwork", i might consider.
[Galaxy Tab S Original Android Development] danny19901:

[Galaxy Tab S Original Android Development] Topogigi:
So, if all is at the right place on the kernel side, the only further requirement for enabling loopback support should be in userspace: a good busybox release (including a loop-enabled "mount" command and a working "chroot" command) should be enough to do the trick. I would try with the stericson one (https://play.google.com/store/apps/details?id=stericson.busybox)

regarding UVC support:

I tried dashcam app from android market and it says "no UVC driver". Seemingly Tab S doesn't have it - while majority of devices now seem to support it. Here is a list. And it is stated that "The ROM must have these options enabled:

CONFIG_VIDEO_DEV=y

CONFIG_VIDEO_V4L2_COMMON=y

CONFIG_VIDEO_MEDIA=y

CONFIG_USB_VIDEO_CLASS=y

CONFIG_V4L_USB_DRIVERS=y

CONFIG_USB_VIDEO_CLASS_INPUT_EVDEV=y

"

Edit:

There is also a new thread regarding UVC support on T-705: http://xdaforums.com/showpost.php?p=57308015
[Galaxy Tab S Original Android Development] UpInTheAir:
Just checked for you, only one NOT enabled in kernel is:

# CONFIG_USB_VIDEO_CLASS is not set

I'll enable it and test compile (with no negative impact) for next release. ;)

[Galaxy Tab S Original Android Development] Daniel Smedegaard Buus:
Previous versions archive?

Hi UpInTheAir :)

I'm having some WiFi issues with the last two versions of your kernel, v2.2.0 and v2.4.0. More precisely, I have to turn off WiFi and re-enable it about once every 30 minutes, almost like clockwork, if I'm using the tablet to stream video (Kodi, MX Player, ...).

What happens is that the transfer speed suddenly drops drastically, and any network activity from that point on until I "reset" WiFi as described, is slow, much too slow to stream HD video from my network, and often makes games like The Simpsons Tapped Out lose their server connections. The 30-minute interval in which it happens is, as described, almost like clockwork, if I use the network a lot (such as trying to watch a movie, which requires me to reset WiFi at least thrice to complete it).

It happened just when I upgraded to v.2.2. But my version of your kernel before that was a v1.something, back when you had to use Odin to flash it.

So two questions:

Any idea why this is happening? Anything I can configure?

Is there an archive of previous versions so that I can revert to an earlier one two resolve the issue immediately?

Thanks,

Daniel :)
[Galaxy Tab S Original Android Development] UpInTheAir:
Other users have report that no WIFI issue, I would suggest to upgrade your base firmware. Edit: You could also try set WIFI power mode to OFF for either screen on/off.

Look in the download section available in Web view. ......
[Galaxy Tab S Original Android Development] Daniel Smedegaard Buus:
I'll give it a shot, thanks :) I assume we're talking about Synapse?

Well, I only see the latest version. Are there no archived ones?

Hi i have a t705 stock rooted running your kernel, after my battery reach zero and turn off i boot it up and show it is 15% do you think i need to do a fuel gauge reset? The battery life itself is not really bad about 4h of sot mostly for browsung and the occasional gaming.

If it is needed is this the correct step: reset the fuel gauge and let drain to 5-10% and then do a full charge cycle again
[Galaxy Tab S Original Android Development] UpInTheAir:
1. FG reset

2. Reboot device

3. Battery % "reporting" calibration (digital)

a) Deplete battery to 5-10% (NOT ZERO)

b) Charge UNINTERUPTED until FULL (don't touch)

c) Unplug and then use normally. Device should then re-calibrate itself

EDIT: I've now added the basic steps to Post #3 HELP & FAQ ;)

[Galaxy Tab S Original Android Development] UpInTheAir:
OK, in the change-log v0.9 > v1.0, the only thing that may make a difference is the screen mirroring / Allshare cast fix is causing you issues???

So I can help you (and others) and possibly add more functionality to the kernel, please:

1. Flash the latest kernel (follow install instructions)

2. Open terminal emulator app

su
setprop wlan.wfd.hdcp enable

3. Turn on WIFI and test

If all works, then this is it, I can maybe add a Synapse control switch to easily enable/disable

.
[Galaxy Tab S Original Android Development] Daniel Smedegaard Buus:
Not sure if that's the last version that didn't trigger my problem. I just tried a very old one because I initially didn't upgrade for a long while, and the one I had before doing so was one of the first Skyhigh kernels, before you made flashable zips, so it was flashed via Odin. And the consensus seemed to be, "No one has any problem but you, so stop talking," so I didn't do any hunting to try to find out at which version the problem first shows — I was just happy it disappeared ;). As described, It takes about 30 minutes of streaming video for it to surface, so it'll take a while to find the one version where it starts :)

But I'll have a go at it, if you want? I could just have the tablet playing video next to me while trying different kernels. It'd be like a manual binary search, I guess :D

Btw, I noticed that the speed WiFi drops to when the problem kicks in is very steady at about 540 kBps when transferring files via CIFS (drops from ~7 MBps (probably capped by it writing to external SD)), not sure if that gives you any clue? I'm also thinking that people might be having the problem and not necessarily noticing, since it's not THAT slow (pornhub would still work :laugh:).

Anyway, I'll start trying out different versions, let me know if you don't want me to anyway :highfive:

BTW: I also tried the latest Oloendithas kernel, and it has the same problem on my tablet.
[Galaxy Tab S Original Android Development] UpInTheAir:
Is not "if I want", because I don't have any issues. Up to you if you wish to help yourself, otherwise use stock or be happy with v0.9 ;)

If your problem is running through CIFS (which you never mentioned before), then I probably can't help. I don't use it.
[Galaxy Tab S Original Android Development] Daniel Smedegaard Buus:
Well, I don't really care as I'm am indeed happy with any old version as long as it works, I just asked to help out in case you wanted to track down a potential bug. I sounded like you wanted to know, so I went ahead and spent the last hours testing different kernels. In case you care, the last kernel to not exhibit this behavior turned out to be v1.1.0.

CIFS, DLNA, or any other network activity does it for me. Doesn't matter what, as long as it pulls a lot of traffic, so YouTube in HD will do as well.

Well, I'm off then :) Cheerio!
[Galaxy Tab S Original Android Development] UpInTheAir:
[MENTION=4142938]Daniel Smedegaard Buus[/MENTION]

EDITED !!

v1.2 changelog is:

I didn't really dont care, but if you narrowed things down for yourself, I might be able to help your case. I can't make magic if I can't reproduce (and none other can either).

As I said in an earlier post SET YOUR WIFI PM TO OFF IN SYNAPSE NETWORK SETTINGS. Did you actually try my suggestion, or overlook it same as "downloads" section ;)

Try different settings to see if they make a difference !

If you're running from CIFS,might be an issue. But likely to stay that way.

Sorry, that's all I can suggest.
[Galaxy Tab S Original Android Development] Daniel Smedegaard Buus:
Well, as I wrote, v.1.1 is the last one not having problems, i.e. the last one working, so it's the v1.2 changelog you should be looking at. The one with all the WiFi PM changes.

Again, "my case" ended when I reverted to a previous working kernel. Everything I've done from then on is narrowing down things for, well, you, in case you're interested.

Have you tried to reproduce it? Again, the drop in WiFi speed will only be really obvious if you're streaming video and the described drop (to ~540 kBps) means you can no longer stream normally. As described, WiFi doesn't stop working — it drops from AC levels to below B levels. Keeps on going, but your traffic will be capped.

Anyway, I only wrote to clarify the version: The problem starts with v1.2.0 with all the WiFi changes and all versions after (that I've tested (which were 1.5, 2.2, 2.4, and 2.5)).

Either way, I'm happy with my now once again normally working tablet. It's been less than fun trying to report on this issue, but I'd like to thank you for your work.

Cheers,

Daniel :good:

PS: As to your edit addendum: Yes, I tried all sorts of WiFi PM settings in Synapse, including forcing it to off.
