[Galaxy Tab 10.1 Android Development] pershoot:
No not from that.

There is one/two freq's that few devices have an issue with (not speaking of overclocking).

This will be rectified on Sunday

Don't forget, only people with issues would normally post. So this is few and far between.

My device itself is fine, so my device is not a good test device, unfortunately.
[Galaxy Tab 10.1 Android Development] pershoot:
In fact I'm going to amend the oc logic a bit, to make it easier moving forward to troubleshoot such issues with the odd ended device.

All will happen as soon as I get back from vaca (sun).

Then I can move on with the other stuff I wanted to bring in, etc.
[Galaxy Tab 10.1 Android Development] mark1962nc:
Yeah, with the exception of one sleep/charge death things have been great for me!
[Galaxy Tab 10.1 Android Development] JStar1033:
Hey pershoot just an idea. Maybe you could have 2 seperate kernels. 1 for people who are stable at a lower voltage and the other that need a little more for 1.4ghz stable.
[Galaxy Tab 10.1 Android Development] OgremustCrush:
I keep trying this kernel, but stock just feels more responsive at 1ghz. Maybe the interactive governor? Never been a big fan of ondemand myself.
[Galaxy Tab 10.1 Android Development] JeffR714:
Good idea on interactive it worked excellent on the Xoom just ran more stable. I'm not a pro at the kernel stuff I just know what seems to run well

Sent from Samsung Galaxy Tab 10.1
[Galaxy Tab 10.1 Android Development] pershoot:
Ogrem,

This kernel is much more responsive then stock.

You must have some instability, which will be sorted when I come back to do that.

Get rid of setcpu then try.

The tweaked ondemand is working quite well and jumps right up and softens back when I need it.

I will not use interactive on high oc's as of yet until I have a chance to look further in to that governor.

Ondemand (tweaked out) works well here and all the other devices I support, so not sure I will get a chance to look in to interactive.
[Galaxy Tab 10.1 Android Development] pershoot:
Jstar, nah too much to maintain.

One size fits all will be fine, after some refinement. I'm used to it by now (goin through some revisions to encompass all the devices out there). As long as mine and users' patience holds up, hehe, we're good!
[Galaxy Tab 10.1 Android Development] OgremustCrush:
That's the thing though, I've tried running both with setCPU disabled, no "set on boot" boxes checked or any settings changed. Scrolling just seems a lot jerkier with the custom kernel, takes longer to scroll between homescreens etc. It seems like if I'm doing a lot of stuff the ondemand eventually picks up, but the initial feel of interactive is superior. I mean I haven't tried running benches or anything, just general usage of the tablet. Not trying to demean your work or anything, I really want to run this kernel. Maybe if I try it again running conservative, I never liked the feel of ondemand on my evo either.
[Galaxy Tab 10.1 Android Development] pershoot:
Ths is not ondemand as you know that's in here. It has been revamped/reworked a bit.

You probly have some instability which is giving this illusion of not working well. Also, yours is the first that I've heard of this, which is also indicative of instability. Wait till Sunday/monday, then try out the next rls.
[Galaxy Tab 10.1 Android Development] LovellKid:
Hey Pershoot... You thinking of any voodoo love for the future?
[Galaxy Tab 10.1 Android Development] pershoot:
Yea will bring it in as soon as I sort this kernel for one size fits all.
[Galaxy Tab 10.1 Android Development] horatiob:
I truly appreciate your diligence, commitment and faithfulness. The effort you are putting into this ROM is nothing short of awesome. I have crazy instability with your kernel. It will be going fine for a while then outta then during heavy network transfers it will lock up. I wish i knew how to send you the logs and stuff but I don't. Also I think I'ma gonna swap it out for the 32GB model. I hope I have better luck with that one...
[Galaxy Tab 10.1 Android Development] pershoot:
If u are attempting to oc, clock down (your device may not be stable with what I am giving currently).

You can send me /proc/last_kmsg (adb pull /proc/last_kmsg .)

At any rate,

Check back after sun/mon's release, and you should be riding fine (non oc'd). Oc, I wont be increasing the high end more at this stage, so if your device can't do it now, it probly wont do it then.

Conversely, my device can do 1.4 all day long with/without large net transfers, etc.

Others can as well. Small minority of devices to sort, and in a week or 2, I should have them covered as well.
[Galaxy Tab 10.1 Android Development] pershoot:
Actually I may increase the high end just a tad bit more so those devices which were on the edge before, can play.

We'll see...
[Galaxy Tab 10.1 Android Development] antonyfl:
would I be correct to say that Supercurio is already working on a voodoo kernel for the tab 10.1?
[Galaxy Tab 10.1 Android Development] pershoot:
He already ported it to galaxy, but some things I believe need to be redone for it.
[Galaxy Tab 10.1 Android Development] horatiob:
I believe mine is "right on the edge," reason: I was fine all day yesterday and all today... at the end of the day i was doing large file transfers and it just locked up after a full two days... maybe a little voltage increase might help... but also I am considering returning mine and getting the 32GB.
[Galaxy Tab 10.1 Android Development] horatiob:
got the file... where do I send it to?
[Galaxy Tab 10.1 Android Development] jim_hardcore:
The sound and screen improvement he was talking about?
[Galaxy Tab 10.1 Android Development] aliirq:
thank you pershoot for your nice job

I flashed this kernel for 3 days now and it is almost perfectly stable at 1.2

I didnt push it to 1.4 till now but I have no problem at all
[Galaxy Tab 10.1 Android Development] SellswordShev:
Just attach it to as post in this thread, with a short description perhaps of how you crashed / froze / etc.
[Galaxy Tab 10.1 Android Development] IDroidThere4Iam:
I've been running this for about 2 days now. So far no lockups or anything adverse. I set up SetCPU using autodetect, ondemand, and I have it running up to 1.4GHz.

I did modify two parameters on the advanced SetCPU screen. First, I changed the sampling interval to 100000 (the default was 300000). I also dropped the threshold from 80 to 60. If anyone has comments on why this might be bad, please let me know. I do feel like it makes things a bit snappier, but it is just a feeling.
[Galaxy Tab 10.1 Android Development] 5thElement:
Reverted back to stock kernel. I like others at first thought the 1.4ghz kernel was great until I started to notice lockups and yesterday the tab10 even rebooted on me while watching youtube at 1ghz. Never had any of these problem with the stock kernel.

I would highly recommend avoiding this kernel.
[Galaxy Tab 10.1 Android Development] joedon3:
You're an idiot. just because it doesn't work for you doesn't mean it doesn't work for everyone else.

OCing your device and even flashing anything custom even if you're not OCing has risks. everyone here is aware of that. If you experience problems with this kernel, you can go back to stock, or help the developer troubleshoot the problem to create a better experience for everyone.

But let people make their own decisions. I've run my Tab at 1.4 since day 1, not a single issue. I highly recommend trying this kernel!!!
[Galaxy Tab 10.1 Android Development] pershoot:
We have been over this, and I am losing my patience with you. Have you been reading the past 20 or so of my replies? I need to make more adjustments. I cannot have it all done magically in one release.

Guess what? I am perfectly stable all day long at 1.4. I cannot crumble it. Tab is my only net device while on vaca. I can watch youtube all day long, long net transfers. Sleep/wake, etc. I know of plenty others that are as well on this very kernel.

Do not spam in this thread again. I will have you perma-banned. That is all.

If you have something positive to contribute, then I am listening. You are ruining this community very fast. I strongly advise you to curb this attitude at once.
[Galaxy Tab 10.1 Android Development] used2hvatreo:
I am entirely positive that your opinions, like all others, belong in the general threads category. This thread is reserved for the development and testing of new kernels, something that is done for free, to benefit anyone who has this fantastic device. You trying to scare people away from a kernel because your tab sucks is just immature and ridiculous.

I would highly recommend you go back to whatever dreamland forum you came from where every FREE release of a development level kernel is perfect, and where the developers clearly love to feed on your opinions and emotions.

I would also highly recommend that you read all of the pages of this thread, where you will see that many are having 100% success with this thread, and in the cases where thats not true, we are working to make this kernel work on there device.

I would also finally highly recommend that if you have a problem with the hardware limitations of your device, that you return it and try and get a different one.

Thanks.
[Galaxy Tab 10.1 Android Development] xefe:
I have a question about 3g. I will buy a 3g 10.1 by the end of the month, does this kernel support the 3G version? Woould be great, always used custom kernels on my SGS and want to try a custom one on the SGT also. Does it increase the temperature much with overclock or its not noticeable?
[Galaxy Tab 10.1 Android Development] pershoot:
I should be able to, as long as the 3g module is available.

Pls pull your device's config for me, and I'll take a looksee for you.

Thx.

No issues running at 1.4. Had it running since 7/2 in the morning. Ill see if I can get thus to crash. Hopefully not. Thanks for the good work.

On second thought, I have ocassional keyboard lag. Still stable though.
[Galaxy Tab 10.1 Android Development] pershoot:
Kb lag is not the kernel.

That's sammie's hc 3.1 issue (didn't happen on 3.01).
[Galaxy Tab 10.1 Android Development] joeski27:
Well I can say that it did work extremely well with bigrushdog's OC kernels for the Xoom. In fact that was the only governor I ever ran with his killer OC kernels and it performed much better than the other settings. :confused:

And apparently, now in the new Bonsai rom (which uses your 1.4 kernel) he has the interactive governor in use and someone who has tested it in that thread said that they saw a 60% performance jump (at least in quadrant scores) when they switched from on demand to interactive. Just sayin. :rolleyes:

[Galaxy Tab 10.1 Android Development] SellswordShev:
Its really just a trade-off between battery life vs responsiveness. It should be added if it's stable, so that the user can choose. So far for me it has been stable, I'm running @1.4 on the bonsai ROM as well

edit: STRONGLY recommend using a screen off profile in SetCPU to limit your max frequency with the interactive governor, not sure if it's changed recently but from what I remember interactive can rampup quite high even when screen is off.
[Galaxy Tab 10.1 Android Development] horatiob:
since i flashed bonsai my tab been flying at 1400 interactive. No lock ups or anything. I am liking it so much that I dont even wanna put it on ondemand or conservative... I dont wanna take the chance of it locking up again.

I just tried your kernel on p7500 indonesia release. Regret to say that it doesnt work. My steps perbelow

get the zip only

flash via cwm

reboot

Screen booted pass samsung logo then my screen is all messed up.

Reboot wipe cache

screen jumbled up

waited 2 minute, can see vaguely my wallpaper and notification sound

but screen still jumbled up.

Reboot cwm restore

awesome !

any chance of adding the interactive governor ? I saw better results with that over the weekend when on the bonsai ROM, with no stability issues
[Galaxy Tab 10.1 Android Development] pershoot:
Not at the moment.

Maybe later on...
[Galaxy Tab 10.1 Android Development] Grommish:
I ran this for a solid 45+ mins @ 1400 using SetCPU's internal stress test without issue. I also ran this for about 2 hours in 90+ degree temps outside streaming HD YouTube videos without issues other than YouTube decides to FC on me twice (It did NOT crash YouTube oddly, or crash the tab. it just went back to the previous video I was watching. I blame it on the video I picked more than anything else.. happened only for that particular video).

Pulled a 83-85 MFLOP consistantly with LinPack and 2065 on QuadranPro.

Pershoot rocks!

Pershoot.. I see there is a TouchWiz hack released out ther for the tab. While I can't stand TouchWiz itself, I want Allshare back. The ability to stream video and audio over my network is def high on my list. AllShare requires some shared Samsung libraries though. Any chance they could be incorporated so AllShare will work?

Edit 2:

Looking around at the various threads, they talk about USB Hosting OTG support being hardware (Pin 13 and 15 on the 30 pin connector) or kernel based as done in some of the Froyo builds for phones. Since we know the hardware support is present, is there anyway to force the kernel to go into OTG host mode so we don't have to either buy or hack up a 30-pin connector?
[Galaxy Tab 10.1 Android Development] Zoide_:
Can this kernel be installed on top of the Bonsai ROM?
[Galaxy Tab 10.1 Android Development] pershoot:
im looking in to it.
[Galaxy Tab 10.1 Android Development] pershoot:
yes. but if that rom has changes in the ramdisk to accomodate init.d script running, you will lose that functionality.

also if that rom is placing the wifi module on your actual system (and not in the ramdisk), then you will have an issue with wifi.

i'd ask the author at any rate.

It would be nice to know if there were specific issues with it before I re-enabled it in my fork. :)

am i the only one getting freeze/reboots every 2 hrs? even after update? :confused:
[Galaxy Tab 10.1 Android Development] pershoot:
are you overclocking (i assume you are)? then,

you are not stable. clock down. im not going to be increasing voltage anymore at this stage.

if you are not, tell me where you are freezing and ensure you do not have a bad app causing this.

thx.
[Galaxy Tab 10.1 Android Development] fit333:
ive tried every possible combination of settings for the last day and a half. is something to do with the journaling feature? i love this kernel because its the only one that alows me to set up cifs mounts for some reason.. but after intensive YouTube /g+ etc i get a freeze and auto reboot, like the ram gets filled up and os fails or something ...any ideas?
[Galaxy Tab 10.1 Android Development] pershoot:
yes, clock down.

turn off any other tweaks that you know are causing you instability.

there should be no issue from extended youtube hd/flash, if you are truly stable at your intended freq. even at 90+ degrees (the other poster). be mindful of your temp tho, it will get warm at 1.4 (top left corner on back).

if you are receiving this at 1ghz on this kernel (0710), remove known tweaks which could be causing issue, then observe.
[Galaxy Tab 10.1 Android Development] fit333:
ye , did all that, but tx..:mad:

will edit when solution is found..
[Galaxy Tab 10.1 Android Development] pershoot:
if you are on the stock system and running this without setcpu installed, you should not be getting freezes at all. there is more then enough juice here to accomodate even the weakest devices.

my advice,

take a CWM backup.

full wipe and flash back to the stock rom.

then flash kernel (0710), then reboot.

quickly re-setup your device then (without installing setcpu; leaving things stock as is), try youtube hd.

if you get a bounce, post your /proc/last_kmsg. if you do get said bounce, flash back to the stock kernel. then try youtube hd once more. if you get another bounce, then there is something else wrong on your system, and further investigation should be done, to rule out HW defect, etc.
[Galaxy Tab 10.1 Android Development] fit333:
ok tx ..will try, (it weird though,that all is great for 2hrs ..)
[Galaxy Tab 10.1 Android Development] Entropy512:
I can understand not making it the default for that reason, but why completely remove it? Some people might want to trade off a tiny bit of responsiveness and Quadrant epeen (Conservative can kill Quadrant scores because Quadrant doesn't "preload" the CPU to get it to ramp - a perfect example of why Quadrant scores are meaningless in the real world.) in order to improve battery life.

Also, it may not be a valid concern for Tegra, but some CPUs don't take kindly to the rapid voltage/clock swings that ondemand entails. Hummingbirds are kind of notorious for instability when overclocked and ondemand...

I enabled Conservative in my fork of your kernel and it's working fine so far. :)

Edit: Which toolchain do you recommend? I'm using CodeSourcery 2009q3-68 (due to newer versions causing stability problems with Samsung Infuse kernels), but can easily start having two toolchains installed.
