I have a 16GB 3G+WiFi model bought in Thailand (build: HMJ37 P7500DXKG7), and have rooted it and put CWM on it.

I'm now looking for a kernel and a ROM. Looking through this thread and other threads I found that "kernel 2.6.36.4" was not compatible with my 3G version, and then I found a 3G version of this kernel in this thread.

a) So what is correct? Can I flash the 3G version of this kernel?

b) ROMs, if I use this kernel (3G version) and flashes a ROM without 3G (Task's for example) - will that work? (except I will lose 3G)

c) if I'm totaly lost, and can't use this kernel - is there any kernels for 3G tablets yet?
[Galaxy Tab 10.1 Android Development] Wubdidu:
I have the same tablet. I flashed the current stock rom KG9 and this kernel works like a charm. I had some crashes in sleep mode (SOD), but in the current version nothing bad happened so far.

Can't tell you anything about using WiFi-only Roms on the 3G... There is another Rom called Broodcomb which is specifically for the 3G tablet.

If you want to help the dev. community for this tablet please try this kernel and report any problems so pershoot can have a look at it. :)

any plan to do an undervolt/underclock version?

but i think it might not make much diff anyway since most power is used by the screen, not the processor.
[Galaxy Tab 10.1 Android Development] nickwarn:
you can use the GT-P7500 version of the kernel it works fine. you can flash any rom on top of this kernel as they all have kernels in them, so they just overwrite the existing kernel. And Wifi only roms work fine on the GT-P7500 only 3G wont work. And there are no other OC kernel for the GT-P7500, not posted on Xda anyways oor anywhere else i looked.

Oh snap....Really? I have this model (European 3G from Germany - Build Number HMJ37 P7500XWKG9) and it DIDNT come with TW, and its running just fine for me. Im not running any custom ROM and still dont have a TW build. Im just rooted and the kernal is working just fine for me.

Should I not be using it? I ve been running it for about 4 days, and its working great so far.

Oh man...now Im confused...maybe I AM running TW and wasnt aware of it?? ROFL! How can I confirm this? I thought TW hadnt been rolled out to Europe yet?

LOL..man oh man do I feel stupid :) Im not sure how to tell if I have it or not! LOL!

EDIT - Ok, after watching a video of TW features, it appears I AM running TW...LOL...sorry for the confusion. :)

Installed the kernel, and trying to get cifs to work. Installed cifs manager, and tried the various options there. But still just get an error "mounting the share has failed with an error. Mount: no such device".

This kernel support cifs right, so what do I do wrong?
[Galaxy Tab 10.1 Android Development] pellegj:
You need the cfis kernel module from lib-2636.4.tar.gz, extract it to the tab, point it out in cifs manager or load with insmod from terminal window.
[Galaxy Tab 10.1 Android Development] rr3636:
thx :) it worked :) I copied the full contents of that tar.gz file and pointed to the cifs.ko file within it. Did I need all the other files, or just the single file (cifs.ko) ?

As I was testing out my HDMI adapter, I noticed that I have the same flickering issue as descriped in this thread. The interesting part was that for some reason the flickering seemed to be more frequent when using this kernel (the overclock didn't seem to have any effect, just the kernel) compared to stock. It would be great if other people could confirm this as it could indicate that the flickering problem is a software issue.

Delete the entry in superuser, autodetect in setcpu, allow it and leave default of allow always, 216-1400 on boot, and you'll be good.

I had this same issue, my tab became unresponsive while trying to load browser or other apps. A reboot "fixed" it. I was advised to move a .nomedia file to /data/media and I haven't had the problem since.

If you don't have the file, I made a zip of a .nomedia file. Unzip and move the file to /data/media and then reboot. See if that helps.

Pershoot:

I updated to the latest kernel and immediately saw increased system lag and less responsiveness. As I test, I dropped back to a previous kernel (Unless you can tell me if it dumps the date into Build-prop I don't know which one because of the naming conventions you are still using on the website.. truncates the filename at the first period) and the issues disappeared.

Of course I only updated because its a revised update, not because of any problems.

Suggestions on what I can provide you if your interested would be appreciated. Again, I've used your kernel since week after retail release without issues and love it..
[Galaxy Tab 10.1 Android Development] pershoot:
your lag is specific to your system and not related to the kernel.

[Galaxy Tab 10.1 Android Development] Grommish:
I can check that, however please note that I specified this occured with the last kernl update ONLY. None of the previous releases had this issue, which is why I'm mentioning it. Indeed, flashing back to the eariler kernel release with no other changes has fixed the issue.
[Galaxy Tab 10.1 Android Development] pershoot:
its not the kernel. if it was, you wouldnt be the only one experiencing it.

this is a known issue with that process, eating cycles. that, and the behavior you described is indicative of it.

to show you how bad this is, this just happened to me just now, and i have a .nomedia file present.

the media process was going wild. i knew immediately as the swiping in app tray didnt look as fluid. this is after i received a market notification for an app update on a fresh power up (after being off for the whole day).

i had to force kill it, then things returned to normal.

ill see if i can write a daemon to watch this process and either re-nice it or kill it, if it acts up.

i was able to substantially reduce the flicker on hdmi, but not completly eliminate it. it is a marked improvement from stock. it is useable and watchable without being too much of a hinderance.

i feel there may be some HW issue, possibly with the hdmi adapter.
[Galaxy Tab 10.1 Android Development] CazeW:
After intensive testing with pershoot, he did indeed manage to reduce the amount of flicker that I was experiencing with stock kernel. I was able to go from pretty much unuseable with flickering sometimes occuring several times per minute to a few or no flicker at all for an hour+. So if you're experiencing the same thing as descriped in HDMI Adapter Problems/Flickering Output, you should give this kernel a test. It most likely wont fix it completely but it should reduce it. If you're still experiencing bad flickering with this kernel, I also noticed that reconnecting the adapter to the Tab sometimes helped.

Big thanks to pershoot for taking time to try to fix this.
[Galaxy Tab 10.1 Android Development] MaximKat:
I've seen people complain about volume level way back and wanted to comment on that. For me the problem is that volume control doesn't seem to do much when headset is plugged in. Basically, there is almost no difference between 20% volume and 100%. For some reason, it works properly with speakers, but not with headphones.

I've tried voodoo, but it only changes the overall volume, but not the control range. It helps if I enable "direct volume control hack", but it's not really a viable permanent solution.

Now, I don't know if this is something that kernel is supposed to do and I also don't remember how things worked with stock kernel, but if there is something that can be done, it would be great.

Always make a Wipe before you install V5 (as Task wrote before) and then zip this wonderful kernel and you will be happy!

Just out of curiosity Pershoot, any reason you limited this to 1.4ghz? Have you tried anything over with success? If it worth doing, its worth over doing :-)
[Galaxy Tab 10.1 Android Development] Serious_Beans:
He answered this question for me before. He said that 1.4ghz is what most tablets can handle so he doesn't want to make a public kernel with higher clock speeds because he would have too many devices to support and there might be instability, so he's sticking to an easy to handle 1.4ghz. I'm pretty sure I summed it up properly or go back like 8? pages and look for his answer.

The blog posts show pershoot is supporting multiple devices, in addition to the 4 seperate "flavours" of the GTab10.1

Perhapse in the future once he can zero in on the "wide range of coverages" for our device he will start playing. Though Sammy's build tolerances seem to be as spotty on the Tab as they are on the phones. Certain devices can only handle so much and others can go much further.
