[Galaxy Tab 10.1 Android Development] pershoot:
kernel rework is goin good.

should have something out in few days which should be solid for:

p7100

p7500-ux

p7510

p7510-ux

this battery oddness should be gone as well (which only seems to effect a small minority of users (apparently it happens on stock as well for a small amount of people)).
[Galaxy Tab 10.1 Android Development] funky81:
thanks..i will wait for your next release..
[Galaxy Tab 10.1 Android Development] nakedninja42:
My battery had started showing the wrong stats after flashing the 0807 kernel. I had been running starburst for a couple days with no issues, then the day I flashed pershoot kernel, I had no issues on the battery stats. That night I plugged in my charger like normal and the next morning it said I was still at the same level I went to bed at which was 31%. So I did a reboot and then it reported that it was 96%, so I plugged it back in for a few minutes and it hit 100%. That's when the issue really began.

Within an hour, I dropped down to 40%. Did a reboot and I was at 92%. So for the rest of the day, my goal was to drain the battery to recalibrate the battery. In the late afternoon, I got to the point that the tablet would shut down as soon as it started up because it was at "0%". I plug in the tablet while shut off and noticed a quarter of the battery still charged from the indicator. After an half hour, I booted up to see what % it was and I was at 76%. We all know that the battery can not charge from 0 - 76% in a half hour, so something was fishy. So that evening I flashed back to the stock kernel and things still did not change. The next day, I did a full wipe and did the same steps you recommend, but the issue did not go away. So while on stock 3.1, I upgraded KG4 to see if that made a difference and I still had the drain (battery stats not reporting right as described before).

So on 0809 when the next refresh happened, I tried again. Stock factory reset, flash CWM, then custom rom and kernel. Still the same thing. I went back to stock that afternoon and ended up doing an RMA in my frustration since no one else was reporting it.

During the entire time, I wanted to do a Battery Stats wipe in CWM but NEVER did until the afternoon before the RMA. Did not make a difference.
[Galaxy Tab 10.1 Android Development] nakedninja42:
Hopefully my new tablet won't have the battery oddness issue :D
[Galaxy Tab 10.1 Android Development] alphaola:
Am not sure if this as already be reported. I flashed the 08 /09 kernel, I noticed the battery quickly went down to 40% from a full charge in few hrs. Then I flashed the stock kernel, after reboot the battery went to 82% which is weird.
[Galaxy Tab 10.1 Android Development] pershoot:
you probably did not have to RMA. you could have rectified it.

i can only assume a patch or two exarcibated the issue for the odd ended device. my device goes on/off usb constantly. no issue at all. i rarely plug it in to power, but when i have, no issue. but that's my device...
[Galaxy Tab 10.1 Android Development] pershoot:
ill pull the last posting if more devices are seeing this odd behavior.
[Galaxy Tab 10.1 Android Development] pershoot:
done. pulled last two.
[Galaxy Tab 10.1 Android Development] alexige:
This is exactly what happens to me. If this is what you are fixing Pershoot I await your fix.
[Galaxy Tab 10.1 Android Development] nakedninja42:
Eh, I am glad to RMA. I have messed with my tablet so much since June, I wanted to have a fresh untouch tablet when the semester starts.

It didn't help that I had just RMA my netbook battery the day before because it stopped charging (issue resolved easily by Asus :cool:). To have both my tablet and netbook not working was an issue to me.
[Galaxy Tab 10.1 Android Development] pershoot:
this is already sorted. as i said, re-building from the ground up.
[Galaxy Tab 10.1 Android Development] alexige:
Glad to hear it!
[Galaxy Tab 10.1 Android Development] Live2Follow:
I am in the process of draining the battery completely. And then recharging while off to full. I have:

Odin'd to 3.01 with stock recovery

Reset in Recovery

Flashed CWM recovery

Wiped Data

Booted into 3.01 Loaded 3.1 TW OTA to Tab

Installed 3.1

Depleted battery completely (multiple reboots to where it would not stay on)

I am recharging while off to 100% +2 hours

If that doesn't calibrate it, I don't know what will. I think that should do it though. I doubt the kernel borked anything serious. I've had this problem on phones, the issues eventually works itself out.
[Galaxy Tab 10.1 Android Development] pershoot:
yea. the battery just needs to be 're-trained'.
[Galaxy Tab 10.1 Android Development] dseo80:
did the training but in docrambones with pershoot - didnt help still erratic reporting
[Galaxy Tab 10.1 Android Development] Live2Follow:
Well it is the risk we take playing with the devices like we do.
[Galaxy Tab 10.1 Android Development] pershoot:
do it on the stock kernel, and you will be fine.

i wouldnt even touch UX which doing it. do it on stock 3.1.

notice that all this wierdness started ocurring on UX? havent heard of anyone running this kernel on stock have these issues. things to ponder..
[Galaxy Tab 10.1 Android Development] muz_aj:
Does anyone have the problem of the draining battery? This version really killed my battery in a strange way, going back to stock for now :)

Edit: I think it just needs calibration, I restarted and it jumped from 32 to 82 :P
[Galaxy Tab 10.1 Android Development] Super-S:
Read the last 2 pages plz...
[Galaxy Tab 10.1 Android Development] smalis:
This exact thing happened to me as well, multiple times. For now, I am running Starburst 8/9/11 w/o pershoot kernel.
[Galaxy Tab 10.1 Android Development] smalis:
Do I correctly understand that after you factory reset with stock recovery, you must use ODIN to flash CWM? If no, how? Can you flash CWM with stock recovery?

Thanks.
[Galaxy Tab 10.1 Android Development] pershoot:
Static screen means u did not flash the right kernel.

If you have noticed, I have pulled the last 2 releases. This includes the ux release.

You must read very carefully before you flash anything. This goes to everyone.

Don't just start clicking and flashing just for the fun of it.
[Galaxy Tab 10.1 Android Development] smalis:
Unlikely, but possible I suppose. While I try to be careful to do things correctly, I am still working at understanding it all.

Looking forward to reworked kernel, many thanks for all your hard work!
[Galaxy Tab 10.1 Android Development] Live2Follow:
Pershoot, you are super patient. I have seen other developers freak at this point. LoL.
[Galaxy Tab 10.1 Android Development] texasredrider:
+1 Heh heh. Thanks for the hard work pershoot!

I thought I was going nuts until I finally read that more than a handful of users are having this issue crop up. Mine acts the same as has been reported.

I also agree that stuff like this is to be expected when we tinker with our toys. Hell, I enjoy flashing, wiping, testing and stuff. Kinda like a hobby, really. Just wish I had the time to actually sit down and learn how to become an Android developer for real.

I look forward to the next release.

Pershoot FTW!

[Galaxy Tab 10.1 Android Development] :
probably a stupid question, and has certainly been mentioned.

But if I install this kernel, how do I get back to the kernel I had before?

Run Starburst ROM and would like to try a different kernel, but if I dont get satisfied, can i go back without any problem and how do i do that?

Which version should i flash on 10.1 16GB 3G with touchwiz

boot-cm_2636.4_p4_ux-oc-xtra-vfpv3-d16_fp suits my hardware?
[Galaxy Tab 10.1 Android Development] pershoot:
neither. it was pulled (the last 2 releases which entailed 10.1 3g support and ux support).

[Galaxy Tab 10.1 Android Development] wojmzy:
thx for enlightment :)

hard to dig trough 133 pages for a start
[Galaxy Tab 10.1 Android Development] pershoot:
your 10.1 3g must be running touchwiz ux in order to run this kernel. i believe all newer devices come with this. i only knew of one person who had a stock 3.1 gt-p7500 device. all the rest had touchwiz on it.

Any word on your reworked kernel for 10.1 wifi? Looking forward to it! <3
[Galaxy Tab 10.1 Android Development] ehe12:
I tried tonight and what a disaster... after I rebooted, the screen suddenly went blur, couldn't show correct image and looked like heavy snow on old tv, never recognise any touch operation. I finally had to flash back to original rom.

I followed the instruction, downloaded the kernel and installed it using clockworkmod, how come this is happening? is there any way to do it right? my original rom was 3.1 europe.
[Galaxy Tab 10.1 Android Development] ehe12:
installation Instructions:

Flash in recovery.

so I downloaded the zip file and installed it in clockwork mod, when I rebooted it just showed the big snow blur picture on the screen, no response to any input. did I do it wrong?
[Galaxy Tab 10.1 Android Development] alexige:
The proper kernel isn't out yet. Probably why your seeing that.

there is no battery issues (i.e. calibration goes off).

the kernel innards have been tested for days straight across various devices, literally beating up that subsystem. on some devices which had it the worst. worst then any 10.1 wifi device had it.

hence the 're-work'.

I had the battery issue previously, had to calibrate using teh stock OTA kernel. Testing the new release for a few hrs now (was running doc slim touchwiz v6.5 with stock OTA TW kernel), all seems good.

Thx pershoot for the hard work. Exist any plan to update the oc up to 1.6 ghz?
[Galaxy Tab 10.1 Android Development] :
So this new kernel is stable and fast? No battery issues?

And have someone tested it with Starburst rom?

For benchmark maybe "Antutu Benchmark " is a better program to use?

Edit.

Running this kernel now, no problems so far.

When running Antutu Benchmark i gets the following scores.

Ondemand 1400mhz and Starburst rom - 5908

Starburst rom only - 4702

And the browser feels faster and smother. And flash performance is better, on some websites the videos that had a little lag before is now running almost perfect.

I ran smartbench immediately before flashing the new kernel and had no issues.. however, I just ran it now and it did work(on the third or forth try). seems be very inconsistent.

Try using CF Benchmark, its free in the Market. It is optimized for dual core benchmarks
[Galaxy Tab 10.1 Android Development] madsquabbles:
it could be b/c you're using profiles and setting your screen off to conservative. when it comes out of standby it sometimes loses your adv settings and won't go back to on demand properly.

i've been using setcpu since it's been rooted and have always had it "on demand" without it changing.

i haven't tried this kernel yet, but i'll give it a go later. being so thin and plastic i'd have to suspect that heat is going to be major factor in oc'ing.
[Galaxy Tab 10.1 Android Development] pershoot:
im not using profiles. cpufreq is losing its setting when it comes out of standby (sometimes). it runs deeper internally where ondemand is hooked in. ill need to investigate it and rectify it.

ive tweaked out ondemand to work a bit better so it keeps things in check (in terms of scaling).
