[Galaxy Tab 10.1 Android Development] IDroidThere4Iam:
I wasn't able to check out my Tab since flashing the test kernel until about a half hour ago. Its been sitting in the dock for over 24 hours. I pulled it off the dock and I had no wifi (also unresponsive touchscreen....power button works and the screen rotates, just can't unlock). Any ways, sometimes after a few screen rotations I can unlock and it happened here. So no wifi, but Tab was responsive at least. I checked for the last kmsg log, found a very short log. I made a copy I've attached. What was weird is after I rebooted to get my wifi back there was no last kmsg file in the proc directory at all. Strange stuff.
[Galaxy Tab 10.1 Android Development] pershoot:
yea the dock is problematic, so it seems.

please try to reproduce again on the dock.

nothing was in your log that pinpointed to the issue.
[Galaxy Tab 10.1 Android Development] pershoot:
-test2 comin up.
[Galaxy Tab 10.1 Android Development] pershoot:
-test2 is up.

please run a adb shell uname -a to ensure it is current.

then dock it and come back to it in 30-60 mins, and see if that behavior comes back.

if it does, leave it be, plug it in, and grab a dmesg log.

pls post it.

thx.
[Galaxy Tab 10.1 Android Development] pershoot:
able to reproduce yet?
[Galaxy Tab 10.1 Android Development] IDroidThere4Iam:
Sorry, haven't flashed yet. Pregnant wife took priority over the past few hours : D

I'm going to wipe and reset my tab one more time to make sure I'm clear with this test. Sorry I'm not moving quicker with this. I'll let you know when its flashed and I'll dock it for an hour and check it right after.
[Galaxy Tab 10.1 Android Development] pershoot:
yup, cool.

congratulations!
[Galaxy Tab 10.1 Android Development] used2hvatreo:
Congrats++

Pershoot, i will test too, i need to charge and have a dock so i will be happy to oblige
[Galaxy Tab 10.1 Android Development] Denkai:
test two isn't working for me. the Samsung GALAXT TAB 10.1 shows up, but the animated graphics do not show up. I get the jingle then a few seconds later the screen goes wierd. I see a bunch of lines of various colors followed by watching the screen scan each line over and over. I think my test2 file might be corrupt. I'll try and redownload.

edit:odd it's not the file, it's doing it with test1 as well, however it is not doing it with the 9/13 update.
[Galaxy Tab 10.1 Android Development] pershoot:
test2 should be fine.

this is only for UX, 7510. you should ideally be on UEKME (but not a requirement).

if your on HC 3.1, this won't work.
[Galaxy Tab 10.1 Android Development] pershoot:
LTE folks,

sammy released newer src. ill diff out the changes and merge when i get some time.
[Galaxy Tab 10.1 Android Development] Denkai:
I am officially retarded. thanks for catching that. wow can't believe I missed that....

on a side note it's odd cause the HC 3.1 worked with the UEKME kernel.
[Galaxy Tab 10.1 Android Development] pershoot:
it wouldn't.

it too would cause inverse scan lines on the screen.
[Galaxy Tab 10.1 Android Development] used2hvatreo:
been on the dock charging for awhile now with no adverse effects. Left it for over an hour and its like i never left it
[Galaxy Tab 10.1 Android Development] Denkai:
that's what I thought... but I double checked myself, it did. but good news so far, left it on the dock for over an hour, still no hang ups. I'll leave it over night and see if it does it.
[Galaxy Tab 10.1 Android Development] pershoot:
if that works, then ill send a test3, for another 24hr observation, on/off dock.
[Galaxy Tab 10.1 Android Development] MagicOnline:
big thanks pershoot for this awesome kernel.

especially the usb-charging option - fantastic job *thumbs-up*
[Galaxy Tab 10.1 Android Development] RustyNailz:
Running test2... Touchscreen was unresponsive when I took it off the dock this morning. Once it started responding, wifi was working as expected. So, this is a definite improvement over prior builds.

If you need them, I captured a dmesg log and also copied the full ksmg log.
[Galaxy Tab 10.1 Android Development] pershoot:
yes pls send it.
[Galaxy Tab 10.1 Android Development] RustyNailz:
Logs

Here you go...
[Galaxy Tab 10.1 Android Development] Denkai:
Well here's the logs. when I first woke it up it hung for two seconds of the screen not responding, but unlocked afterwards no problem. I literally watched as the wifi disabled itself. after the screen locked itself back I went to wake it up and now touch screen is unresponsive.

Still running 3.1 UX without OC or any kind of mod

as for the wifi thing I don't know if this means anything for you but the type of signal I'm connecting two is a N type 5 ghz frequency. I doubt it matters but I figured I'd put it out there.
[Galaxy Tab 10.1 Android Development] RustyNailz:
Here's another dmesg log from test2. This time the screen was unresponsive and it hadn't been on the dock since this morning. When screen started responding again, wifi was stuck in the "Turning off..." phase and I has to reboot to restore wifi functionality.
[Galaxy Tab 10.1 Android Development] IDroidThere4Iam:
I've been running test 2 for about 1.5 hours now. No problems yet. I have gone 2 or 3 days sometimes without my Tab freezing or losing the wi-fi so I'll keep an eye on it.

Also, Im not sure the dock itself is an issue. I have had freezes and lost wi-fi without being on the dock. It was sitting on my dining room table once and I lost it. I also just hooked my dock back up a few days ago, so it may just be that charging the Tab exacerbates the problem, which is more consistant with my experience.

Any ways, running test 2 finally, I'll report back after work tomorrow (eastern time zone for me).
[Galaxy Tab 10.1 Android Development] pershoot:
ill link up with someone with a dock on gtalk, to better understand what is ocurring, so i can work towards rectifying it.
[Galaxy Tab 10.1 Android Development] Highriser:
Any issues?

Are there any issues with the 9/12/2011 kernel release that would make it better not to flash? I've been reading through the thread, but I can't really tell if the problems are on the current release, or on the test kernel.

Thanks!
[Galaxy Tab 10.1 Android Development] pershoot:
9/13 is the latest.

if you have and use a dock, things become problematic.

other then that, it is rock solid.
[Galaxy Tab 10.1 Android Development] Hironimo:
I'm using ROM version XXKI1.

To that i've applied kernel boot-cm_2636.4_p4_ux-oc-xtra-vfpv3-d16_fp-091311.zip - overclocking works and quadrant score improves (though not that much as I would have liked).

However:

The home screen is not as fluid as with the stock kernel - stutters are more frequence and it feels more sluggish (doesnt seem overclocking matters here).

Is this known? Is there anything that can be done here?

Also I wonder: the configuration to force usb charging - is it only available with the pershoot kernel?
[Galaxy Tab 10.1 Android Development] pershoot:
no idea whats in that rom.

silky smooth over here.

yes, usb charging support is only in this kernel.
[Galaxy Tab 10.1 Android Development] nickwarn:
Using the same kernel and Broodcomb KI1 and its smooth as hell. Try setting it to interactive it seems to work best. Also want to say thank you to Pershoot, your doing great work here man and this place would be very boring with out you.
[Galaxy Tab 10.1 Android Development] Kurupt1:
Yes great work pershoot, thanks for the hard work
[Galaxy Tab 10.1 Android Development] IDroidThere4Iam:
Running test 2 this morning and within about 5-10 minutes of putting the Tab in the dock my screen was unresponsive. I still had wifi so I left it sitting there. I checked again maybe another 5-10 minutes later (so total max about 20 minutes on the dock) and I had no wifi, but my screen was responsive (go figure!).

Attached is output from dmesg and also the last_kmsg.
[Galaxy Tab 10.1 Android Development] pershoot:
sorry. havent had time to sit down and work on this.

ill try in the next few days.
[Galaxy Tab 10.1 Android Development] armanys:
Can I use it with my P7500 3G tablet??....I have Broodcom ROM, not pure stock!

And how can I install, if yes?
[Galaxy Tab 10.1 Android Development] IDroidThere4Iam:
Thanks for your help and all the time you already put into this.

Attached is another set of logs. I think the dmesg output in this one is a lot more helpful. There are some eth0 failures within it.
[Galaxy Tab 10.1 Android Development] BBLV:
Is there any way to increase the max volume through the tabs speakers? I have the latest versions of pershoots 7510 wifi kernel and Task650's ROM, which are both awesome by the way. I also purchased the Voodoo Control app earlier and have been playing around with it but don't see a way to increase anything besides the line-out volume... when the media volume level is maxed its loud but not that loud. When the media volume level is at half its very, very quiet... any tips?
[Galaxy Tab 10.1 Android Development] Grommish:
Ironically, pershoot turned DOWN the volume because people compained it was too loud
[Galaxy Tab 10.1 Android Development] mystifiyer:
Would an option to disable logcat be considered?

It works wonders for SGS but given that Tab 10.1 ain't exactly fast. would it helps?

I had previously posted in Broodcom thread but since its more of kernel than rom related, hence decide to repost my suggestion here.

Thanks
[Galaxy Tab 10.1 Android Development] sixstringsg:
When we actually tested turning Logcat off on the SGS, we found it didn't do much. I am one of the devs of the Glitch kernel, and we compared them side by side, and it didn't give much performance increase. Theoretically it would, but not enough to notice.
[Galaxy Tab 10.1 Android Development] Denkai:
hey pershoot dunno if this will help you or not but I've done five clean wipes with the stock recovery and had it occur with and without the dock being used. Not sure if the dock is the issue, as it's occurred without it ever being connected.

as a dumb question but I remember on the Cliq the "ghost touches" was due to the recovery not wiping a particular directory, Not sure if the stock recovery ever did wipe it or not. I know the stock wipes /data/media (the "SDCARD" for those who are wondering), however, does it truly wipe everything? is it possible the issue is caused due to flashing a different kernel and your kernel is encountering something on our systems that isn't getting wiped?

I'm probably fishing but hoping to unleash an "aha!" moment for you.
[Galaxy Tab 10.1 Android Development] mystifiyer:
Thank you for the explanation. It has been insightful.
[Galaxy Tab 10.1 Android Development] armanys:
Can u tell me if I can I use it with my P7500 3G tablet (with Broodcom ROM - which is aprox. sock rom)??!

I can install it thru CWM?

Nobody???
[Galaxy Tab 10.1 Android Development] Grommish:
Once again, ROMs are written for kernels,not the other way around.

ROM writers tend to include a kernel in their packages for this reason. If you want to know if it'll be compatible, you have three options..

1) flash and pray.. be ready to lose everything if you have to ODIN back..

2) talk to the ROM author. Pester them to include pershoot's kernel in their release.

3) ask (as you have) but be prepared for no answer if others haven't tried it.

Pershoot has already stated he will only support the STOCK roms, of which there are now 4.. (non-tw, twux, 3g, and LTE). Deviate from them, and you are running solo.

These are your options and risks. Proceed accordingly.
[Galaxy Tab 10.1 Android Development] ck_looi:
Can this kernel be used in GT P7500?
[Galaxy Tab 10.1 Android Development] mabalito:
What's up with all the people asking if this kernel works on the GT-P7500? Learn to read maybe?
[Galaxy Tab 10.1 Android Development] tiny4579:
People don't choose to read, they post without reading the thread. The answers are available in the thread and pershoot's website.
[Galaxy Tab 10.1 Android Development] The Root:
Can I use this on my cable box? :-p
[Galaxy Tab 10.1 Android Development] mabalito:
You can, just flash it to your tab and put your tab on the cable box ;)
[Galaxy Tab 10.1 Android Development] Grommish:
I tried it. range was so short its unusable and it just shows colored hash. did i flash the wrong kernel?

;-)
[Galaxy Tab 10.1 Android Development] jackie_jagger:
hey guys, been following the thread since a while ! I have a 3G tab (P7500) just curious which is the best version to install because I am seeing few posts about lock ups and tabs getting hung.

My primary use of the Kernel would be for NTFS support and gaming controllers support - not a fan of overclocking !

Please advice, Thanks !
[Galaxy Tab 10.1 Android Development] pershoot:
there is only one version. that is 9/13 (which is the latest).

read the 'known issues'.
[Galaxy Tab 10.1 Android Development] used2hvatreo:
The best version is always the latest. Generally a release is pulled if its not stable, but thats rare these days. Pershoot has a group of people that test the heck out of these kernels before they go live. He puts a lot of time and effort into making sure that the kernel is a good product before it flies.
[Galaxy Tab 10.1 Android Development] pershoot:
those with docks, please test.

[Galaxy Tab 10.1 Android Development] Entropy512:
This makes sense to me.

Logcat and dmesg usually only go to RAM and not to the filesystem - and even at its chattiest, logcat isn't putting enough into the logs to possibly have anything but a negligible effect on RAM.

The disadvantages of disabling logcat and dmesg (making debugging impossible) GREATLY outweight the miniscule (if any) advantages.

If an app or kernel driver is spamming the logs so much that it affects performance, the app or driver needs fixing - disabling logcat/dmesg outright is an absolutely poor bandaid over the root problem.

It's like putting a gigantic band-aid that covers your eyes and tapes your mouth shut over a minor shaving nick.
[Galaxy Tab 10.1 Android Development] slack04:
Searched the thread and didn't see anyone else with this (in fact, only the opposite). Posted a similar question on task's thread. I'm on your 9/13 kernel and task 650v7.1 and there's something with the volume. It's way too loud on the lowest setting. I'm in a library and I can't use my Google music because it's blaring out of my cans! Any idea of what's going on? The difference between off and volume at "1" is huge, but minimal from there up to maximum volume.

Thanks dude!
[Galaxy Tab 10.1 Android Development] pershoot:
Use voodoo cp to control it.

It may also be at fault, but majority wants it in, so leaving it in for the interim.
[Galaxy Tab 10.1 Android Development] Grommish:
Pershoot

What version of voodoo is baked in. i ask because on the og epic forum theyve had issues with 10 and reverted to 9
[Galaxy Tab 10.1 Android Development] quinn12:
Flashed the latest version of Overcome and loaded both versions of Pershoot. I keep getting these lines. Any idea what's going on? I'm out of ideas and couldn't find any thread or post regarding this issue. It seems the two are compatible for everyone else's Tab by mine. Thanks guys.
[Galaxy Tab 10.1 Android Development] stormglove:
I just had this issue too when I tried to install the kernel. I just purchased and rooted haven't done too much research on the device so I will continue to read the thread and others but I would love to have this kernel work if anyone could help. Thank you in advanced for any help.

Grommish, 10. Latest for gtab.
[Galaxy Tab 10.1 Android Development] pershoot:
Storm,quinn,

Stop and read very carefully (the posting where you downloaded the file to flash). Then you will find out the issue you had and its fix.
[Galaxy Tab 10.1 Android Development] stormglove:
I think I see what your talking about pershoot, thanks. In my excitement to root and start flashing I didn't see that we have to move that file over. Thanks again and I'm looking forward to trying out the kernel.
[Galaxy Tab 10.1 Android Development] pershoot:
Ensure you flash the right kernel for your device/rom.
[Galaxy Tab 10.1 Android Development] Grommish:
The hash error happens when you flash the wrong kernel file for your device. there are 4 versions of the kernel depending on which gtab you picked up..

Rodderick over in the Epic 4g area pulled 10 from the Genocide2.0 due to sound issues and put back 9. people where losing their sound and other wierd issues. wonder if something in 10 is causing some of the wierd, hard to track issues?

version was the first thing I checked and it was correct, thank you for that though. And again thank you pershoot.
[Galaxy Tab 10.1 Android Development] pershoot:

[Galaxy Tab 10.1 Android Development] Denkai:
anyone thought of a way to get the:

adb shell echo 1 > /sys/class/power_supply/battery/force_usb_charging

to run automatically when usb is plugged in? I thought about using tasker, but I suck at setting up the program. I thought about writing a udev script but I don't know the usb driver on the tablet and I don't think android works with udev anyways...
[Galaxy Tab 10.1 Android Development] pershoot:
Scroll up. I posted how to accomplish this.
[Galaxy Tab 10.1 Android Development] quinn12:
Pershoot,

Thanks for the assist. I see the message regarding the custom roms that you moved the wifi files, etc. I hate being a noob and asking these basic questions, but which files do I move where and from where and to? Again apologies for being ignorant to how these things worked. I have rooted the system however so I have filessytem access. Thanks again.
[Galaxy Tab 10.1 Android Development] pershoot:
download proper file from droidbasement, move to /data/media, flash in CWM.

that's all.
[Galaxy Tab 10.1 Android Development] quinn12:
Actually, that's what I was doing. But the same result.

boot-cm_2636.4_ux-oc-xtra-vfpv3-d16_fp-091311.zip

Even tried: boot-cm_2636.4-oc-xtra-vfpv3-d16_fp-091311.zip

but I got the same issue. Am I doing something wrong? I am versed in how to flash via CWM as well as ODIN but I feel there's something I'm leaving out or just not noticing. I appreciate the help though. It's righteous of you.

ROM: Overcome v. 1.1.0
[Galaxy Tab 10.1 Android Development] pershoot:
For overcome you would use ux (i gather).

I am unsure of what is exactly in there.

Please check with the author on compatibility, etc.

Do people use the headphone control in voodoo? Or is it unuseable in its current form, on this platform?
[Galaxy Tab 10.1 Android Development] SeanHacker:
If you're talking about the headphone amp. Yes. It works for me. Makes the music louder when Ive got my tab hooked into my stereo.
[Galaxy Tab 10.1 Android Development] Denkai:
yea I rock the G2 kernel. to bad it doesn't do voodoo :)

I'll flash the new one (test3?) right now and leave it over night, let you know what I get.

I was debugging the system and noticed when I run watch_media.sh I'm getting a:

watch_media.sh[16]:syntax error: 'if' unmatched

I assumed that it was self induced. and it was. not to everyone use notepad++ instead of wordpad. not sure why it was giving me a syntax error on line 16, I removed formatting from the file after adding but whatever.
[Galaxy Tab 10.1 Android Development] Entropy512:
Could be very likely device-port-specific. I've seen no problems specific to V10 on the Infuse, for example. The only documented VS bugs on the Infuse are audio routing to the dock (likely didn't work in V9 either) and an audio volume bug that was specific to CM7 due to CM7's different audio routing.

Yes. Worked fine for me last time I tried it, but I haven't touched kernel or ROM in a few weeks due to being busy in RL.

This issue seems to occur so sporadically (at least for me) , so it will be a few days before I'll know for sure.
[Galaxy Tab 10.1 Android Development] slack04:
Thanks Pershoot. Voodoo CP at least lets me turn the amp down enough to use the tab in the library, but there's still the issue of there being almost no difference from lowest to highest volume. I like the dynamic bass expansion, but it's not worth it to me.

Anyways, thanks for the help. I'll continue to (happily!) use your kernel, but count this as a vote for removing the voodoo sound in a future updatel.

Thanks dude!
[Galaxy Tab 10.1 Android Development] Denkai:
bad news is it happened again, unfortunately I didn't have logcat catch it. I've reset and have an active logcat recording everything in a log via putty.
[Galaxy Tab 10.1 Android Development] pershoot:
this test is only to rectify issue with docks.

no idea what issue your having. its definitely something that no other tab seems to be having. none that i or others can reproduce. without seeing the issue laid out, i cannot see what is going on, if indeed you do not have a hardware problem.

post specific kernel logs, but if they don't display anything, im afraid there isn't much i can do for you, as i'd be flying blind, since it can't be reproduced.

yes, the inability to turn off wifi (rare ocurrence) and/or it going off and needing to reboot to get it back does happen on the stock kernel. few have had this. it may be a HC UX issue on this platform.
[Galaxy Tab 10.1 Android Development] The Root:
How much are docks?
[Galaxy Tab 10.1 Android Development] Entropy512:
I'm able to get PLENTY of volume adjustment out of the amp - far more than is possible with just the stock volume controls.
