do a search on the thread for stock kernel, thats how I found it. I don't remember the post #
[Galaxy Tab 10.1 Android Development] MarcAntonyy:
I may be wrong, but doesn't flashing Pershoot's Tools Pack flash you back to the stock kernel?

That's what I did and I'm pretty sure it took me back to stock.
[Galaxy Tab 10.1 Android Development] pershoot:
correct.

stock kernel + insecure boot (adb root shell).
[Galaxy Tab 10.1 Android Development] used2hvatreo:
unfortunately i'm dumb and didn't read, yes thats correect
[Galaxy Tab 10.1 Android Development] pershoot:
it bundles a kernel in there as well for flashing, along with the tools stuff.
[Galaxy Tab 10.1 Android Development] player4lifeov:
How is the battery life when running this kernel, thanks?
[Galaxy Tab 10.1 Android Development] Grommish:
I cannot compare to stock, but I went almost three days between charges with heavy use. Wif was on whenever the tab was on.
[Galaxy Tab 10.1 Android Development] rainby:
same here , no wifi issues
[Galaxy Tab 10.1 Android Development] foethalove:
Has anyone noticed if this kernel had helped with the keyboard lag in the browser? I haven't noticed it since flashing.

Great job pershoot ! Everything smooth. I appreciate how much snappier task switcher is
[Galaxy Tab 10.1 Android Development] mbh87:
Did I miss the refresh? Pershoot told me last night not to flash the one up because he was going to post it but I dont see it. Im assuming he didnt get to it but was curious.
[Galaxy Tab 10.1 Android Development] PhantomHacker:
From Pershoot himself.
[Galaxy Tab 10.1 Android Development] G1_enthusiast:
so that is the most recent? Cause it says the 23rd
[Galaxy Tab 10.1 Android Development] PhantomHacker:
On the blog is the preview kernel, I believe.
[Galaxy Tab 10.1 Android Development] ofcsu1:
Don't flash anything yet. He removed the kernal to work out the kinks and the bugs that users were experiencing. Just wait until he has it ironed out and puts it back up for the public.
[Galaxy Tab 10.1 Android Development] mbh87:
Skipped right over that, I even looked through the thread. Thanks.
[Galaxy Tab 10.1 Android Development] Zoide_:
The latest file is from the 24th: http://droidbasement.com/galaxy/kernels/2636/preview/

I guess we have to wait...
[Galaxy Tab 10.1 Android Development] MarcAntonyy:
I think the Pershoot KernelTM is in 'Closed Beta' atm.

;)
[Galaxy Tab 10.1 Android Development] used2hvatreo:
Rest assured you guys will be very happy with outcome. pershoot has put a lot of time into making this kernel as close to perfection as possible
[Galaxy Tab 10.1 Android Development] hkoutso:
Not to mention his excellent work on the Nexus One kernels ;)
[Galaxy Tab 10.1 Android Development] pershoot:
Sorry guys still working on this with various testers.

Almost there with knocking out most of the stuff.
[Galaxy Tab 10.1 Android Development] PhantomHacker:
Awesome, can't wait.
[Galaxy Tab 10.1 Android Development] aSeeker:
Looking forward to having this on 10.1v also - the stock rom isn't a debug/dev build - which makes debugging apps a PIA - many of the android sdk tools won't run against end-user builds.

Emulator performance is sluggish at best.
[Galaxy Tab 10.1 Android Development] Zoide_:
If only the moisture under the screen could be debugged away :(

Edit: Sorry for the OT post... Many thanks to pershoot for his awesome work with the kernel!
[Galaxy Tab 10.1 Android Development] G1_enthusiast:
No rush but EtA?
[Galaxy Tab 10.1 Android Development] antonyfl:
soon. Let the man work his magic :D:D
[Galaxy Tab 10.1 Android Development] Archangel:
I trust that he will have it fixed, this current version freezes at various points and have to force a reboot.
[Galaxy Tab 10.1 Android Development] PhantomHacker:
That's the preview.
[Galaxy Tab 10.1 Android Development] used2hvatreo:
You are correct, pershoot is making positively sure none of those problems exist in the release. It is well worth the wait, he has done some great stuff
[Galaxy Tab 10.1 Android Development] Knight2011:
Maybe it's just my tiredness but i can't find the stock kernel.

I tried the tools pack, but it won't flash. Anyone have a direct link?

Thanks
[Galaxy Tab 10.1 Android Development] IDroidThere4Iam:
If you made a nandroid of your system prior to flashing other kernels you can restore only your boot partition in the advanced menu of CWM which should bring you back to the stock kernel if that is what was installed when you made the nandroid. That is how I did it, worked great.

I'm pretty sure what I wrote is a run on sentance. Definitely time for bed, haha.
[Galaxy Tab 10.1 Android Development] horatiob:
Hey Pershoot, any chance of a 1.6 kernel? I know you said you would not be releasing it to the public. My guess is for "Safety Reasons." But if we are not stable at 1.6 we'll just slow it back down to 1.4, or 1Ghz. So please if you have something you are working of please share it. If not I understand and respect your decision. Thank you for reading this and thank you for your time...
[Galaxy Tab 10.1 Android Development] pershoot:
Thanks to nakedninja42, Rlcohen70, concept0, used2hvatreo and proengin for the assistance in testing!
[Galaxy Tab 10.1 Android Development] drae52:
Nice work bro I was waiting for release to flash, super smooth.
[Galaxy Tab 10.1 Android Development] Fyahstarter:
Crazy fast...crazy smooth! Great work!
[Galaxy Tab 10.1 Android Development] SellswordShev:
sweet! looks great so far. ~85 on linpack, ~2050 on quadrant :D.

I noticed that the build# has 'cyanogenmod' in it, is this merged with cm7 in places ?
[Galaxy Tab 10.1 Android Development] pershoot:
no merge. i just keep the -cyanogenmod in it (its historical).
[Galaxy Tab 10.1 Android Development] roccos_van:
Get some sleep ;)...and thanks for the hard work!!
[Galaxy Tab 10.1 Android Development] mark1962nc:
Just reporting.....tab died while on charge.

Using latest release.
[Galaxy Tab 10.1 Android Development] Fyahstarter:
Tab still freezing at 1.4. Stepping down to 1.2 to see how that works.
[Galaxy Tab 10.1 Android Development] used2hvatreo:
what were you doing when it froze? I'm going to try and recreate any issues you have so that Pershoot can make adjustments
[Galaxy Tab 10.1 Android Development] EvoXOhio:
Was it the sleep of death?
[Galaxy Tab 10.1 Android Development] :
Package with xtras link is broke.
[Galaxy Tab 10.1 Android Development] Riztnack:
My tab froze at 1.4 while listening to music
[Galaxy Tab 10.1 Android Development] used2hvatreo:
Please drop down to 1200 and see if it still happens
[Galaxy Tab 10.1 Android Development] Akarim47:
Flashed the latest, installed set CPU. OC to 1.4 restarted the tab. Connected the charger and now the tab won't wake up? Any idea?
[Galaxy Tab 10.1 Android Development] JeffR714:
Modules

Don't want to be a pain after doing this for 2 years I think I can do the things I need to to keep my devices running rooted and overclocked. But the kernel modules seem to be a problem I know how to push them I did it with the Xoom but there were only a few and then he just included them in the kernel. Now I need a little help I don't know which ones to install or which modules are needed to have the kernel run. Any chance I might get a little help? I really would appreciate it. I have the kernel at 1.4GHZ seems to be running great
[Galaxy Tab 10.1 Android Development] Akarim47:
It just won't wake up. Any idea if it's dead or not?
[Galaxy Tab 10.1 Android Development] EvoXOhio:
Worked for me. I will say that i have never been able to flash one of these kernels via rom manager. It will go to cwm, try, and then fail. I have to boot to cwm and then manually do it.
[Galaxy Tab 10.1 Android Development] Knight2011:
Thanks. Yea, i got too tired and gave up for the night before something got bricked. Evo 3d vs Galaxy Tab lol
[Galaxy Tab 10.1 Android Development] Akarim47:
ok, i guess the tab just turned off, so I pushed the power button with the vol down then went to recovery and full wipe, restored the back up (the one I made before flashing the kernel and installed set cpu) now it's working and will wait till we hear from the dev.
[Galaxy Tab 10.1 Android Development] pershoot:
Long press power and hard shutdown then power to come back up.

Charge as in wall or to usb? Please be very specific. Post logs and flash off of the kernel. I will look at it when I return.
[Galaxy Tab 10.1 Android Development] pershoot:
Usb or wall? Please be very specific. Long press power to shutdown and then come back up. Post logs and flash off of the kernel.
[Galaxy Tab 10.1 Android Development] pershoot:
All,

If you are reporting an issue I need logs and be very specific.

This kernel has gone through various testing from various people. It is expected that a small minority still experience issue.

Do not report an issue if you are not stable on your overclock. Clock down and try to reproduce it. Then report that with a log in hand.
[Galaxy Tab 10.1 Android Development] Akarim47:
well I'm back to stock kernel, but if it helps it was wall charging not USB
[Galaxy Tab 10.1 Android Development] pershoot:
Pls post logs. It us difficult to fix something without it.

/proc/last_knsg

If its not there flash back to kernel, try to reproduce, post log then flash off the kernel.
[Galaxy Tab 10.1 Android Development] SS2006:
I o tab still freezing at 1.4

Will try 1.2
[Galaxy Tab 10.1 Android Development] pershoot:
To anyone that receives this sleep issue while screen off, pls pm me so I have your name on the list, and I will send you a test image in a week (when I get back from vaca).

So far I count 2 since the rls this morning. I and my testers cannot reproduce the issue. We've been hammering/abusing it for days.

Please get me a /proc/last_kmsg as well.

Thx.
[Galaxy Tab 10.1 Android Development] Fyahstarter:
Sorry for the late response. I was actually flipping through some pics on Google+. Was thumbing through pretty fast and then freeze.
[Galaxy Tab 10.1 Android Development] pershoot:
If you are overclocking, clock down.

If you are not, then thoroughly test each freq step (you can do this by limiting your max), then report back at which step, and I will make an adjustment.

Thx.
[Galaxy Tab 10.1 Android Development] OgremustCrush:
Just got a lockup while doing a speedtest using the website while set to 1.2. Downclocked and will see if stable at 1.0 on this kernel.
[Galaxy Tab 10.1 Android Development] OgremustCrush:
Tablet just got really laggy on this kernel, even after reboot. Switching back to stock seemed to fix it.
[Galaxy Tab 10.1 Android Development] SellswordShev:
I've got a freeze @1.4g with new release, the last 6-27 kern had been working fine for me for 4-5 days though (moderate - heavy use). Lock up happened when using Nook + Grooveshark in background. I'll clock down and see where I can get stable

edit throwing up dmesg if thats any use
[Galaxy Tab 10.1 Android Development] mark1962nc:
It was on the wall charger.....sorry I'm on vacation and don't have my usual setup to pull logs. Off charger it wakes without issue and everything else is very smooth....oc to 1.4.
[Galaxy Tab 10.1 Android Development] SellswordShev:
you can pull last_kmsg and demsg using just connectbot on the tab

open a local terminal in connectbot and use these commands

su (grant super user in the popup)

cat /proc/last_kmsg > /mnt/sdcard/last_kmsg.log

demsg > /mnt/sdcard/demsg.log

sdcard directory should now have the logs saved in files last_kmsg.log and demsg.log
[Galaxy Tab 10.1 Android Development] JeffR714:
Only problem I have is the lag tapping from one homescreen to the next oh and keyboard lag other than that it runs fine
[Galaxy Tab 10.1 Android Development] SellswordShev:
are you running autokiller ?

if not try that with a 325,350,375 profile, did wonders for me
[Galaxy Tab 10.1 Android Development] rainby:
Off topic question about the profile u mentioned ....is this from setcpu or your own profile ? I. Didn't see any preset in the app, thanks.

I run Pandora for streamingmusic. 1.4 and 1.2 will cause lockup. Back to 1 then no problems.
[Galaxy Tab 10.1 Android Development] 5thElement:
Are there any other kernels available for the tab10 that overclock? This one seems to be causing alot of problems. :(
[Galaxy Tab 10.1 Android Development] JeffR714:
Excellent suggestion downloaded auto memory killer used your settings an I'm noticing a major difference thanks for the great tip
[Galaxy Tab 10.1 Android Development] used2hvatreo:
Currently there is only one because the thing has been out for two weeks to the Gen public. Have you tried it yet? I have been running the latest version without a hiccup for days. One of the problems currently is different tolerances per different devices. Give it a try and see what happens, you can always go back to stock if you don't get it workng
[Galaxy Tab 10.1 Android Development] 5thElement:
ok im flashing now. I have the 16gb unit.
[Galaxy Tab 10.1 Android Development] SellswordShev:
If youre getting lockups then stay at stock clock, OC will always vary from device to device, though pershoot may try to further stabilize things.

The profile I mentioned has nothing to do with setcpu, its an autokiller profile:

https://market.android.com/details?id=com.rs.autokiller&hl=en

If you were just curious about the numbers, I came up with those just from trying what worked best
[Galaxy Tab 10.1 Android Development] 5thElement:
So I finished flashing it and have been running the tablet at 1.4ghz for the past hour or so with no issues. The tablet runs SIGNIFICANTLY faster now which makes me really happy. :)

I also found that general scrolling is much smoother when you use the Performance setting instead of the OnDemand setting. Seems like the speed stepping gives scrolling tiny hickups.
[Galaxy Tab 10.1 Android Development] hoodoomagic:
Umm, when you use the performance governor you're keeping the cpu clock maxed that's why.

You should keep it on demand for normal use with this kernel.
[Galaxy Tab 10.1 Android Development] 5thElement:
Scrolling through menus IS normal use. lol. For example scrolling through the Market is much smoother when you set the cpu to Performance instead of OnDemand. The stepping of speeds causes hicups in scrolling unfortunately :(
[Galaxy Tab 10.1 Android Development] 5thElement:
well my tablet froze at 1.4ghz. I left it on Performance mode at 1.4ghz to see if its stable for long periods of time. After a few mins of using it at 1.4ghz the unit froze. All I was doing was scrolling through the market.

Oh well, this kernel is very unstable. Has anyone else made a kernel that works?
[Galaxy Tab 10.1 Android Development] bootsie99:
as always they are very stable congrats great work
[Galaxy Tab 10.1 Android Development] Berner:
So let's see if I have this correct: You used the kernel for all of 4 hours, and did so pegged at redline despite recommendations to the contrary. When you experienced a problem, you neither (a) downclocked to 1.2 or 1.0, nor (b) posted logs as requested by the developer.

Instead, you: (1) publicly dismissed the kernel as "very unstable"; and (2) asked a question that had already been answered for you in the same thread.

What a fine addition to the community you are! Is it too late to suggest an ipad for you?
[Galaxy Tab 10.1 Android Development] pershoot:
Ogremustcrush,

check your bg apps and ensure you are stable at the freq u are intending to run at.

Both indicative of slowdowns.
[Galaxy Tab 10.1 Android Development] pershoot:
5thelement,

Clock down

Your device cannot do 1.4 on this kernel. Sorry.
[Galaxy Tab 10.1 Android Development] gdog1977:
I've put it though about 3 hrs of heavy use at 1.4, seems really stable and finally FAST. Thanks a bunch.:D
[Galaxy Tab 10.1 Android Development] foethalove:
I had been getting some freeze issues at 1.2 and have clocked down to SV for the last two days. still getting some of the same freeze issues. Have had it happen in both QuickOffice and Stumble Upon apps. Screen becomes completely frozen, menu buttons non responsive, volume not responsive and I am forced to hold power to boot down. I hope I have included the correct log if not let me know.

Thanks for all of your hard work pershoot.
[Galaxy Tab 10.1 Android Development] 5thElement:
Any Tegra 2 can EASILY handle 1.4ghz regardless of manufacturing tolerances. The 40nm process used has zero issues running at 1.4ghz. Im sorry but this is a problem with the kernel not the device, seeing all the issues people are having support my claim. Sorry, the kernel just needs more work right now...
[Galaxy Tab 10.1 Android Development] pershoot:
Dude, i am very familiar with tegra2 and its tolerances.

Your device needs more voltage to operate at 1.4. I am not willing to give more.

WRONG, not all tegra2 devices can handle 1.4 easily. If you were familiar with all of them, you would not have made that statement. I'm not talking about juicing the daylights out of a device to get it to go either.

You want it, pull my src, adjust and rebuild to your liking. If not, clock down.
[Galaxy Tab 10.1 Android Development] pershoot:
You should be so lucky that someone is willing to spend half their life on something that can work harmoniously across thousands of devices. Rome was not built in a day, and I cannot attenuate for all of the devices out there in one release.

If you do not want to contribute, please keep your idle comments to yourself and out of this thread.

Thank you.
[Galaxy Tab 10.1 Android Development] pershoot:
For all the others getting freezing (I'm counting about 4 now) at stock freq, I will make adjustments when I get back from vaca.

For those getting sleep wakeup issues, I have a hunch as to what it could be, and I will send you a test image when I get back.

To all,

Please be very specific when you post an issue and with a log in hand.
[Galaxy Tab 10.1 Android Development] 5thElement:
Im making my own kernel actually and should have it completed by next week. IMO you are going about developing this kernel the wrong way. You are changing too many attributes based on the word of the general public which is an uncontrolled environment quite susceptible to errors and I have already seen people here unknowingly give incorrect false information you u and you acted on it and changed the kernel....this is not the way to develop, you need a controlled environment not trial and error guessing by the general public...
[Galaxy Tab 10.1 Android Development] pershoot:
Good for you.

Good luck.

Ill keep my lengthy android experience and kernel engineering in here.

Any source you use don't forget to credit. Would hate to see anything rehashed/rebadged without proper credit.

Also some advice, don't bite the hand that feeds you (especially when its something for free).

I love criticism, but criticism such as the one you have given, I can do wiithout (it helps no one).

Good luck to you and your future endeavors.
[Galaxy Tab 10.1 Android Development] prosive:
Thanks for the hard work, pershoot! I know many of us here deeply appreciate it. I was wondering if you were going to include tun.ko support in the future?
[Galaxy Tab 10.1 Android Development] pershoot:
Tun is built in.

If your specific app needs it modular I will make it in to a module for the next rls.
[Galaxy Tab 10.1 Android Development] jm6001:
Hey pershoot

Downloaded a tegra 2 game off tegra zone and after you install it you have to download content for itto complete and it froze during download of the new content,, i will post klog
[Galaxy Tab 10.1 Android Development] pershoot:
Thx.

can u pls test the range (do this by limiting your max) and let me know which you have an issue with?

I'm fairly certain I know which range to bump up, to attenuate for the odd ended device, but want to confirm.
[Galaxy Tab 10.1 Android Development] FricoRico:
Let's hope that with your attitude you will be able to post your much more awesome kernel on XDA before you get banned. Until you've proven yourself, behave or get out!

That's all that has to be said, let's not waste posts on this any more.
[Galaxy Tab 10.1 Android Development] pershoot:
Also there is no such thing as overclocking in a controlled environment. I wish. I'd take a few devices, adjust, and done.

If it were only that easy.

The fabrication/manuf. process alone creates imperfections where every cpu and envmt is just a lil different then the next. This is why you need some trial end error across many devices.

I have been overclocking mobile devices for a while, and there is no difference here as to overclocking desktop pcs (also been oc'ing them for a long while). Except here I have to attenuate for thousands of devices and ensure stability is key throughout all of them. Where desktop, I only have to worry about myself.

So with that being said, it is a community effort to create something great and in a short time we will have something great. Will take a little bit of time, but we will get there.
[Galaxy Tab 10.1 Android Development] Grommish:
I, for one, am stayin here regardless. Pershoot is active and willing to help. To say the man process has no tolerance is assinine.. its like saying a car engine can is the same without variance! If that was the case, the dyno tuning industry wouldn't exist (at 150/hr no less!).

Per, enjoy the vacation!
[Galaxy Tab 10.1 Android Development] pershoot:
Rest assured, I will sort the remaining issues swiftly, for the odd ended device (which I cannot reproduce on my own device).

I will mull over an increase in voltage, for said devices, so they can do 1.4. Many now can, but some are left out of the party. I favor less heat, better battery life and not too much voltage for longevity of components,, above all else. We'll see....
[Galaxy Tab 10.1 Android Development] antonyfl:
Thanks for all u have done for the community , and here's to more success in your Future! Ignore the trolls.

On topic : would love to contribute but I haven't a clue on how to start posting logs. Perhaps you could whip up a quick tutoria ln the op?
[Galaxy Tab 10.1 Android Development] pershoot:
Ill attach this to the blog posts.
[Galaxy Tab 10.1 Android Development] antonyfl:
Here's my log. im getting a lot more freezes running 1ghz no overclock vs the preview kernel. How do i flash back to stock?

PS I'm on retail running stock rom

http://db.tt/yYBYihI
[Galaxy Tab 10.1 Android Development] pershoot:
Flash the latest tools pack.

Ill rectify this when I return on Sunday for your device and devices like yours.
[Galaxy Tab 10.1 Android Development] ofcsu1:
Just had a crash. Tab was on for about 10 hours in sleep mode while I was out all day. Was listening to an audio book with the default music player and browsing stories in pulse when everything froze up and the tab restarted by itself. Using setCPU at 1.4 ghz max with on-demand governor. First hiccup I've experienced so far.
[Galaxy Tab 10.1 Android Development] EvoXOhio:
I've been running this final kernel since it came out at 1.4 ondemand, and just got my first freeze today. I am not in a position to provide logs I am just posting this FYI. I just downclocked to 1.2 and will see how it goes. I was just browsing the web when it happened.
[Galaxy Tab 10.1 Android Development] RustyNailz:
I had a freeze earlier today while trying to view a Youtube video.

Last_kmsg log attached.
[Galaxy Tab 10.1 Android Development] gdog1977:
Things have changed for the worse for me, system had started to get slow, really slow. Figured out that going back into setcpu would fix the issue. So I uninstalled it alltogether and I havent had a slow down yet.
[Galaxy Tab 10.1 Android Development] pershoot:
Yea sometimes u may be stuck on a low freq. Uunsure why setcpu does that.

Echo the values yourself to cpufreq if u run in to further issues of that sort.
[Galaxy Tab 10.1 Android Development] pershoot:
Also for those receiving sleep wake issues, uninstall setcpu and then observe. Ive seen a similar issue occur on another tegra2 platform.

Will liaise with coolbho3k regarding it.
[Galaxy Tab 10.1 Android Development] danielsjam:
Been watching this for a while now before I dive back in. It seems that most of the lockups are happening while using the network connection. I maybe wrong.
