Can you help me a bit with the apps and steps? What stock kernal should l try. I have paired and used the device with previous roms, but i do not recall which.
[G Tablet Android Development] pershoot:
clear dalvik and re-flash the rom your on now. when your booted back, in do the pairing.

if success, reboot, flash this kernel, then do the pairing. if failure, try again, and run a adb logcat >logcat while doing do. then do a adb shell dmesg >dmesg

paste both files to pastebin.

That's strange. It should report something (usually).

Pls redload the lib file and repush from it, and try again.

Then:

PLease excuse me, I am an idiot....got it loaded just fine. Had the tun.ko on my desktop but wasn't cd'ing to desktop before I pushed the tun.ko file...so I was pushing the wrong one the whole time...sorry and thanks for the help. Now to try and get "vpn connections" going.

[G Tablet Android Development] pershoot:
dont set it.

leave things as they are.

nv's driver takes precedence so the selection wont be there. it is set as default in the kernel. it does have an impact, although may not be as prominent as other devices.
[G Tablet Android Development] xmr405o:
Thanks! I left it alone. If I read it correctly, you have it set "on demand" as default and I don't even need to check set on boot too.

BTW- This is exactly what this forum needed especially the past few days. I could care less about Nvidia and Viewsonic drama.....right now. :p

I've tested your GB kernel. I'm gonna try going back to a froyo based ROM and then try that kernel. To be honest, Froyo and an OC kernel is all I ever needed. You just put a tear in my eye. haha.
[G Tablet Android Development] pershoot:
i believe you still need to launch the app to get the setting, but it retains the last values set.

let me test that, and ill update the post.
[G Tablet Android Development] pershoot:
you need to also have set on boot, if you want it on boot. the last values set are retained though.

If I limit it to 1GHz, is the voltage the same as stock? that is, is there any power disadvantage using this kernel at 1 GHz.

That said, I plan to push it sometimes!

Thanks for your great kernels!
[G Tablet Android Development] pershoot:
im unsure what stock sets at 1GHZ at various times, per se, but i believe DVFS gets set to 1275mv, at stock.

it is now 1100mv at 1GHZ.

ill try to get a test out tonight with further reduced voltages, if possible.

1GHZ max is what gets set automatically when you boot in (unless you use set on boot via setcpu, to your own value), so you need not do anything further to limit it.

[G Tablet Android Development] Synman:
Considerably
[G Tablet Android Development] wd5gnr:
Now that I've played with this a bit (and its great, thank you sir!) I thought I'd share my take on what profiles to set in SetCPU. These are totally made up so maybe there is a better way to set it up. I don't know.

Priority 100: Screen Off. 216/216

Priority 90: Battery<15% 456/216

Priority 85: Temp>38.9C 816/216

Priority 30: Charging AC 1400/608

Priority 20: Charging 1400/608 (see below)

Priority 15: Temp >0.0C 1200/312

Notes:

One of the charging ones does not work unless it is not plugged in and then it is plugged in. I forget which one.

I kept the priorities so that you'd get the slowest speed. So I didn't want battery temp up and battery life down, but I wind up with a faster speed!

I could not figure out a way to just tell it "default" so I figured Temp >0.0C would do it.

So far so good. Anyone else tried this? Any thoughts on a better scheme? Does anyone ever see the battery temp go up?
[G Tablet Android Development] pershoot:
i am unsure if the reported battery temp in setcpu is detecting properly on this device.

i will reach out to coolbho3k and see if we can work out a solution.
[G Tablet Android Development] pr0cs:

[G Tablet Android Development] Archangel:
One last thing whats up with the "In order for UMS (USB mount) to work on Gingerbread, this must be reverted" I went to the site and downloaded the zip do i have to flash that before your kernal?
[G Tablet Android Development] pershoot:
if your running the latest vegan ginger from gojimi, you can disregard that.

there is nothing to dload from that github link for flashing. its source code.
[G Tablet Android Development] xmr405o:

[G Tablet Android Development] Roxxas049:
Well I haven't had many problems with any of the tweaks or roms that I've installed since I got my Gtab 2 months ago but now this newest kernel with the overclocking that I want so badly has seemingly borked my wifi. I've tried forgetting and scanning, it sees my network but says it's out of range even when I'm sitting right next to it.

I'm running the latest vegan gb rom.

Any ideas?

Edit for fyi when I flash back to clemsyn's gb kernel I get wifi back.
[G Tablet Android Development] pershoot:
you did not flash the right file if it says scanning.

_gb in the filename.

please re-read the blog post carefully. then re-download and re-flash.
[G Tablet Android Development] Archangel:
I installed and setCPU does not go higher than 1000?

Nevermind I am stupid and I know it can get real old when people like me do not read all of what we should I forgot to select custom, thank you for your hard work and help!

This new kernel definitely makes a difference on how my tablet functions when overclocked. As mentioned above, it doesn't take a big hit on the battery either. Just ran the smartbench 2011 and scored higher than the xoom clocked at 1.5.
[G Tablet Android Development] ralex76:
Hi Guys,

I am newbie about these things, but at the sime time excited to try them!.

In few words I ve got a gtab with the stock rom (tap ui 1.2-4349) kernel version 2.6.32.9-00001-g0e0c333-dirty. I never changed anything expect using z4root for getting root access.

What steps should I go follow up to install this kernel?

Maybe if you can explain me through simply words the steps it would be great.

Thanks in advance

Alex

[G Tablet Android Development] JinxtPhoto:
I'm on the new Vegan 7.0.0 RC1 and after flashing the new Kernal (inb4 "did you dl the right file?") my WiFi doesn't work anymore. In the system settings when I try to turn WiFi on it just says "error" underneath "WiFi".

I've re-booted and even tried toggling airplane mode to see if it might knock something loose but no-go.

I'm going to try to re-flash the kernal over the current system and if that doesn't work I'll load my backup and try again from stock Vegan 7.

Just thought I'd get a heads up if anyone had any ideas before wasting the time and still not having working WiFi.
[G Tablet Android Development] nitefallz:
Been waiting for this, but only getting around 2200 now on Quadrant Standard. IO seriously takes a few minutes to complete.
[G Tablet Android Development] pershoot:
if it says error then you either did not flash the right file or the wifi module did not get copied over properly, and/or it was copied over in a corrupt state.

pull it from the .zip and copy it to your system.

wifi works fine.
[G Tablet Android Development] pershoot:
it does not come oc'd when booted in. it is 1000 bootup clock.
[G Tablet Android Development] pershoot:
not the kernel.

either reinstall launcher pro and/or clear cache, for a dalvik rebuild.
[G Tablet Android Development] pershoot:
this is most likely not going to flash properly on the 4349's stock recovery build

please nvflash to a custom rom, then flash this kernel over, if you would like to run it.
[G Tablet Android Development] rob_z11:
Well, I updated kernel on Harmony ROM, and it worked great, but when I left my tablet overnight, my tablet was turned off, and when I rebooted, I kept getting acore.process has stopped errors, and has FCS on most of the apps.

I cleared the cache and dalvik and reinsalled the ROM and kernel, and same problem.

I am restoring the ROM from backup, and will try one more time to see if I can get it going.

Anyone else is having problem with Acore.process?
[G Tablet Android Development] pershoot:
robz,

Ensure your wifi is set to never sleep (I assume your on the stock'ish froyo build).

This is outlined in the blog post.

The wifiservice is bugged in the stock froyo frame when working with our method of injecting the newer module.

This is a not an issue on cm7. Only the stock/stock'ish froyo builds.

Reflash your rom clean (clear dalvik) and ensure you set wifi to never sleep.

If the flashing procedure messed up your data structure, you may have to wipe. You can also try fix permissions.
[G Tablet Android Development] hitekredneck:
Flashed and everything is running well as far as I can tell.

I do have one question though, I am currently running on CM7 stable release. Am I supposed to use the CPU setting in the CM settings, or am I supposed to use SetCPU for this Gingerbread CM build?

All other CM builds that I have used state specifically to NOT use SetCPU but to use the built in settings.

Thanks for the great work pershoot, now I am just itching to get into the OC settings and see what this thing will do. Keep up the great work!!

HTR
[G Tablet Android Development] pershoot:
That function is not working right now within settings.

Its on the list to fixup.

Use setcpu for now.
[G Tablet Android Development] hitekredneck:
Thanks for the quick reply, will get SetCPU and see what damage I can do. LOL

To all,

it is imperative that you not only read through this thread but also every posting on the blog, when posted.

most of your questions have been answered. most of all issues can be avoided with this ideology as well.

if you still have questions, then please ask.

please do not flash until you have absorbed and digested the needed information, as it pertains to you.

thank you.
[G Tablet Android Development] hitekredneck:
I tried doing that but was limited on time. It would be nice to have a link with a reference point in it to the first post concerning this OC kernel. That way we would all know where to start reading and could find the pertinent information much more quickly.

[G Tablet Android Development] bschrib:
I'm getting this problem as well - Perhaps not minutes, but definitely the longest portion of the test for me, around 30 seconds I'd say. My scores are fluxing between 2300-2500 with the kernel clocked at 1.4GHz on Vegan GB RC1.

Anyone else have any idea what the IO issues are and any possible resolution? Also of note (not sure if it matters, can't find a good answer anywhere) my tablet doesn't appear to have a dalvik cache? I get an error when I try to wipe it.
[G Tablet Android Development] Zaphod-Beeblebrox:
Process.acore errors are usually related to a borked contacts DB.

If you can get into settings/app management, find contacts and 'clear data', that will usually fix it.

Of course it erases your contacts too (but if you are syncing with Google or exchange they will come back.
[G Tablet Android Development] pershoot:
i would rebuild and reflash fresh (your rom).

something is definitely wrong in your case if your getting odd errors, cant clear cache, and/or other strange behavior.
[G Tablet Android Development] bschrib:
Thanks for the quick response -- The kernel is amazing, the device does seem snappier -- I'll try another reload. So far I haven't been able to buck this problem with the cache though, it's when I try to clear the dalvik-cache from the advanced options menu. I get the following error:

E: Can't mount /dev/block/mmcblk0p2 (File exists)

I'm just sort of assuming that everyone else gets this same error at this point, because from the reading I've seen it appears this is the SD-Ext partition, which maybe we dont have since it's internal memory? idk...
[G Tablet Android Development] pershoot:
when you clear cache from wipe menu, can you clear cache properly?

are you using CWM0.8? can you please flash to CWM0.8 and then try again to clear cache?
[G Tablet Android Development] bschrib:
I can clear Cache OK from wipe menu, no errors. It is only the dalvik-cache that I encounter the error on.

I am currently using CWM0.8 but I'll try re-flashing it and then clearing cache, etc. again and start fresh. I've already done this previously after doing an NVFlash -> CWM0.8 included as part9.img.. Just at a loss on the dalvik-cache stuff. Anyways after I reflash I'll post my quadrant info.
[G Tablet Android Development] pershoot:
clearing cache from wipe menu should be sufficient.
[G Tablet Android Development] jmdearras:
It seems to report the battery temp. That's what it always matches in other monitors.
[G Tablet Android Development] jmdearras:
I always get that error, was told to ignore it.
[G Tablet Android Development] bschrib:
Thank you! I've been dying to hear that someone else gets this error too! I was so confused because I see a lot of posts that talk about clearing the dalvik-cache but that seems pointless if we all get errors. Anyways that alleviates some confusion for me so thanks again.
