Will do. I will charge it first and then let it sleep for couple of hours.
[G Tablet Android Development] JinxtPhoto:
That's what it was. Something must not have gone right with the flash because the system files from the zip were not in the tablet's system folder. I extracted the zip, copied the wlan files to where they should have been, changed the permissions to rw-r--r-- as they should have been and went back into the system settings. Turned WiFi on and "boom", works perfectly now.

I wonder what could have happened during the flash. OC works perfectly, been watching TV shows with RockPlayer all morning with no issues. SmartBench2011 works fine and shows similar results to other peoples' posts, but Quandrant will not display results and errors out after posting results but before being able to display the score. Not a FC, an application error.

Just to be safe I'm going to do another nandroid backup, NVFlash, install RC1 fresh, flash the new kernel and then recover the data partition from the backup just so I know it's good from the start.

Thank you for all your work and sharing these kernel updates with us. I'm anxiously awaiting NVidia letting loose the new harmony drivers so we can get GB HW video acceleration. Once that's done these tablets will truly shine (aside from the crap display panel that is).

Excellent --

I performed the followings steps and am now getting 3000+ benchmarks in Quadrant.

NVFlash (w/cwm0.8 replacing part9.img)

Enter CWM and flash data/cache/system/boot x3 each

Load Clemsyn/Calkulin combo

Load pershoot's OC Kernel

Start up tablet, installed 16 apps (including quadrant)

Anyways I'm going to finish loading the rest of my apps (About 80 more) then see if it bogs down my I/O read stuff -- I don't feel it should, but it certainly makes my boot times take a lot longer when I have all that stuff installed.

Thanks again for your hard work pershoot!

Does this kernel (or is this something the ROM has to do?) provide dual-core CPU support? CM7 at least only seems to access/see a single core.
[G Tablet Android Development] pershoot:
both cores are used (with cpu1 shutting down when not needed). whether the app uses it or not, is debatable.
[G Tablet Android Development] ls430cw:
Just flashed on Calkulins by clearing cache and rebooting. Had to unintall and reinstall Set CPU. Runs great. Thanks for the hard work!

[G Tablet Android Development] Dueces99:
Could someone please post the steps specifically that they used to successfully flash this kernel, preferrably starting from flashing Vegan GB to flashing pershoots kernel to benchmarking? Ive read every post in here and practically every one in the Vegan GB thread, and havent come across someone actually listing the steps taken to get this running.

IE: nvFlash to bekit 1105 image (which I did), clear/wipe/mount etc...

Did you boot into the ROM first, then flash the kernel? Or flash the ROM format/clear/wipe etc then flash the kernel in the same session?

Not saying I havent gotten it running, I have and am seeing considerable gains when running Quadrant, SmartBench 2011, and NenaMark before and after. Theres just a couple areas where my numbers on average are literally almost half that of majority the screenshots Ive seen here.

Specifically in Quadrant (I understand it isnt the most reliable, but still a benchmark for data), the numbers I'm getting for I/O(1300~) and 3D(599~) seemed skewed when compared to other results Ive seen (I/O:2800~ and 3D:1000~).

I've made a spreadsheet showing values for the 3 benchmark apps before and after the OC kernel, if someone wanted to see it for a better idea Id be happy to provide.

Thanks for any insight anyone can lend, and Pershoot beautiful work as always!

P.S.: Anyone by any chance tried running the Data2Loop tweak alongside this kernal/ROM with success?

@Duces99: Have you installed SetCPU, set the CPU type to custom, and actually overclocked it?

From Pershoot's blog:

How-To:

-Install the latest SetCPU (2.11a is current) from the market and/or XDA (http://xdaforums.com/showthread.php?t=505419)

-Select custom

Note:

Be aware, that if you leave it pinned to max, hammering it, it will get warm/warmer then your used to at 1GHZ, pinned.

It is advised not to select any of the 2 governor’s listed (but, at the very least, not performance).
[G Tablet Android Development] TEK112:
Pershoot, as always... job well done!

It is like a new tablet. Just awesome.

Now, I'm gonna do the typical user thing... The new kernel is awesome, but now my refrigerator doesn't seem as cold.... can you fix that?

lol!
[G Tablet Android Development] adampdx:
I forgot to set to custom, but after that everything worked as promised.
[G Tablet Android Development] Dueces99:
I apologize for not clarifying initially, I have done everything needed in the proper manner and have seen noticeable gains. Dont get me wrong, this is working and in flying colors no doubt about it (attached the spreadsheet showing my numbers).

My only concern is more of a perfectionist/pride/envious undertone :) . See, I pride myself on following directions to a 'T' and most of the time, the numbers I get on my tab are just as high if not higher than what I see on here. So you understand when I'm seeing the numbers I'm getting being almost half compared to what others are getting, I can only assume there was a small minuscule step somewhere that they did that I did not.

Sorry if my post was misleading you to think I'm having problems with this kernel, I most certainly am not, neither with this ROM (it's amazing!). Just more of a 'get as much as I possibly can outta this' kind of mentality.

Note: In the spreadsheet, mainly look at my numbers for I/O and 3D AFTER the OC kernel, I'm seeing numbers literally twice that amount and not sure why, help!
[G Tablet Android Development] hitekredneck:
Aha! Therein lies the problem, I downloaded the kernel to my keydrive this morning before work intending on doing my research and install at work during slack times. But it seems that my organization deems your blog worthy of blocking and stated that it was "uncategorized: Sites in this category may pose a security threat to network resources or private information, and are blocked by your organization" so I had no way of reading up on it from work. Thanks for the answers, they are really appreciated.
[G Tablet Android Development] pershoot:
all,

how's the kernel working out?

sleep/wake is ok?

fall from load to idle ok? (in use)

rise from idle to load ok? (in use)

pls let me know.

thx.
[G Tablet Android Development] geological1:
Can I just flash this without wiping data/cache etc??

I don't want to reinstall everything and I think I made that mistake one my first kernal update.

Doesn't setting wifi to never sleep result in battery drain?
[G Tablet Android Development] geological1:
Man you are fast.

Thanks pershoot!
[G Tablet Android Development] pershoot:
nope, it does not.

wifi uses barely any power.

it will hibernate when it goes to sleep after some time, and wake back up when you turn on the screen.
[G Tablet Android Development] rob_z11:
Can you clearify how to pinned to max? I can't select any two governor's listed? Is this only available in paid version?

I have widget of SetCPU running, and I am polling every 60 seconds, and it is shows various frequency range, but not 1400 all the time.

1400 is the max what I have set.
[G Tablet Android Development] Synman:
wake from sleep seems to lag a little (takes a couple clicks of the power button from time to time) but it hasn't failed me yet.

Extremely stable so far for me.
[G Tablet Android Development] pershoot:
do not select any. leave it as is.

it will not go to 1400 unless needed (pass a certain thresshold).

if you want to pin it, min: 1400, max: 1400. only do this if you are in a benching session, and not in normal use.

be mindful of your device, when overclocking.
[G Tablet Android Development] pershoot:
you shouldnt have to repeatedly click. maybe up to 2 (rare) when it could be busy.

i myself have hit that thing countless times. very consistent (it does mess up from time to time tho due to the delays/time loops in place, but much better then it was in stock).

what rom are you using?

ill see if i can add further logic to the function, to try and remedy that for your specific device.
[G Tablet Android Development] rob_z11:
Why would People want to do that? No, mine is 230 min and 1400 max, and I am reading to see if I can create few profiles based on my usage.

Just curious, why I can't select any governor's?
[G Tablet Android Development] pershoot:
performance will let it gravitate to max quickly on a static climb. you dont want this.

conservative will be reluctant to climb. this would kill your in-use useability.

ondemand is the default governor (with some enhancements/tweaks) in this kernel, with nvidia's driver taking some precedance.
[G Tablet Android Development] wd5gnr:
Working quite well here. The only anomalies -- and I can't reproduce them:

1) Last night I jammed the on off button to put it to sleep and then I went to sleep. This morning I woke up and the screen was on! I had a lot of battery burned out over the course of 6 hours, but not bad actually. I don't know if it had come on for some reason 10 minutes before I woke (no, not using its alarm clock) or if it had been on for most of the 6 hours. I suspect it had been awhile though since I lost a good bit of battery.

2) I did see one isolated case where the speed was up at the max (1200 for me on batteries -- see my other post about how I have profiles set) and only a reboot took it back. CPU usage did not appear high.

Now I have other problems that I do not think are kernel related but nothing bad. Biggest problem is that VEGAn Ginger takes upwards of 4 minutes to start for me. But I don't restart often so...

If I haven't said so, thanks for your work on this.
[G Tablet Android Development] rob_z11:
Well, it is good to know that default in ondemand. My selection of scaling is all greyed out.. Just curious if scaling is only available on paid version?
[G Tablet Android Development] rover442:

Hi Pershoot

It's been two days with this kernel. No issues to report. YAY!

I'm not sure if it works but I set my SetCPU profiles and actually set it to underclock when the tab's screen is turned off. Do you think that's even necessary?
[G Tablet Android Development] ls430cw:
Have been using for the last couple of hours and no issues at all.
[G Tablet Android Development] pershoot:
that is a bug where it could come on after an event (plugging in/out, pressing power button too hard (and it registering in the time loop, and waking up), etc. i will look in to it. it happens to my test device here, but very rarely.

you should leave your screen off at 10 mins. you probably have it set to never right now.

it must have been doing something that warranted it staying there and/or it was on its way to fall and the monitoring app did not get refreshed.

the bootup.. do you have a lot of apps loaded on to the system?
[G Tablet Android Development] pershoot:
scaling is not avail, because nv's driver takes some precedance.
[G Tablet Android Development] bso44:
Gotcha. Thank you sir.
[G Tablet Android Development] pershoot:
you dont need it, in my opinion.

i will work with coolbho on the temp thing/accuracy of it, so that actual profile can be setup and utilised.

screen off will be the lowest freq.
[G Tablet Android Development] bso44:
So do most of you guys have your min set to 230?
[G Tablet Android Development] pershoot:
there is no 230.

its 216, with pllx0 generating some after that, for the frequency.

leave min at 216.

For CM7

Guy's is this (boot-cm_2632.36_gb-oc-uv-xtra-vfp_fp-041411.zip) the one I need to download for CM7? the reason for asking is... It's only 2.85 Mb. usually my Captivate kernels are about 6+MB.

+ do I need to do something in SetCPU after Flashing.. (Cos if its Not necessary then I might Not install SetCpu as well)

Thanks in Advance.
[G Tablet Android Development] pershoot:
correct.

that is the one you want for CM7.

there are no extraneous modules in there (.zip), and the compression method used on the kernel itself keeps it compact.

if you want the extra functionality of modules, grab the lib pack and push the desired modules to your system.

Hey just thought I'd give you my notes since you asked.

1.) NVFlashed device, using the CWM 0.8 recovery in the NVFlash as replacement for part9.img (just a simple rename, outlines in another thread somewhere around here).

2.) After NVFlash finished I turned the device off then turned it back on and went directly to the recovery and proceeded to flash all partition (except dalvik-cache) 3x each.

3.) Installed Clemsyn/Calkulin combo ROM.

4.) Installed pershoots OC Kernel

5.) Reboot into the ROM, configured first-run settings and setup Google account.

6.) Install SetCPU from the Market, then open SetCPU and set frequencies for custom (bottom choice), then raise the MAX speed to 1400 and leave MIN untouched.

7.) Install Quadrant, run and enjoy benchmarks in excess of 3000. :)

Sorry that I don't have a data sheet to attach, I might do one later but my home PC lacks ADB support for this device.. Windows 7 x64 refuses to install the drivers damn it all.

Duh.... it is now. Shame on me.... it was a fresh install. I should've known better too.

Sleep/Wake: Works well most of the time, a few issues with long delay coming out of sleep but only seems to happen if I sit idle for longer than 30 minutes and had been running something memory intensive beforehand (e.g. Internet Browser)

[G Tablet Android Development] pershoot:
the delay could be up to ~1 second before screen turns on. i had to put that in there to combat issues with the stock froyo based rom, and it locking up if it woke too fast.

Assistance Updating Kernel

Hello,

I've followed the instructions provided on this post and on the blog.

I wanted to try out the overclocking Kernel however I get to the last step and I get the below error.

insmod: init_module '/system/lib/modules/bcm4329.ko' failed (File exists)

I've never tried doing a kernel update and this is a new file from the forum post. Any help is much appreciated. I am using the VeganTab Gingerbread RC-1 Release, has anyone had any success pushing the new kernel on the VeganTab Rom?

Thank you
[G Tablet Android Development] bschrib:
I kept trying with the VEGAn RC1 ROM but never got it to work properly. Kept having random issues (either items wouldn't load, or market items wouldn't download. Was frustrating). Loaded up Clemsyn/Calkulin's ROM and then pershoots new OC kernel and things were the best I've ever seen. But in answer to your question, no I didn't have no love with VEGAn RC1.
[G Tablet Android Development] dharr18:
I have this kernel running with Vegan Ginger. The only issue I ran into was having to wipe cache and davlik. Everything else has worked fine.
[G Tablet Android Development] Dueces99:
Also have this running on VeGan Ginger RC with absolutely no issues. Seeing SmartBench 2011 scores averaging 4707.20, see this post for my spreadsheet:

http://xdaforums.com/showpost.php?p=12930813&postcount=712

Havent had any FC's, every app/game Ive thrown at it installs and runs flawlessly. Bar-none the fastest and most stable ROM I've tried yet. My Quadrant scores should be higher (from what I've seen elsewhere here), but that could be due to the version Im running (1.1.6 vs the newest 1.1.7) or just how its a finicky app. Biggest thing I've learned when flashing these ROMs are the steps taken in loading them. Afterall, the devil's in the details ;) Hope this helps, everyone should be running this ROM in my opinion.

[G Tablet Android Development] Dueces99:
Pershoot, I swear you are really a machine posing as a human whipping these kernels out as fast as you do. I was just considering nvflashing again (ran into a little problem trying to implement the fps tweak), and you just gave me the perfect reason to do just that! Amazing work!

Just outta curiosity, has anyone tried using the Data2Loop mod on top of the Vegan GB/OC kernel combo? So hard for me to steer away from it after seeing the obvious difference it made in benchmarking, even after reading about the possibility of data corruption (havent experienced this myself however).

Also, pershoot I've used the fps mod few times before (installed same way as well), there any reason why you left the fps at 50? Only ask, cause after loading it Nenamark only showed an increase from 50 to ~52 (using the Vegan 60hz version) so was just wondering if there was any reason why it showed such a small increase. As always, I am forever grateful for the hard work you and all the devs here put in. Thanx!
[G Tablet Android Development] Dueces99:
Highest I got was 3209 which perturbs me since Ive seen scores around ~3700. What version of Quadrant are you running?

Edit: One thing I noticed making a difference in benchmarking was increasing the min clock value. Wasnt substantial, my numbers did consistently increase. Also try running whatever benchmark youre using a few times successively, although Pershoot advises against it "It is advised to keep your min value at 216."

@pershoot

So I have a question which has probably been answered before, but I feel a refresher is in order. What exactly does the kernel do? As I understand it the kernel is the middleman between applications and the OS and the hardware. How do your changes effect how the OS interacts with the hardware of the particular device you are developing for?
[G Tablet Android Development] jguy:
Why am i unable to set the scaling? Option is blacked out.
[G Tablet Android Development] pershoot:
this question has been answered.

scroll up.
[G Tablet Android Development] pershoot:
kernel is the heart (depending on the context) and/or brains (depending on the context), if you will, of the OS. it is the layer between the OS and the hardware.

most of android is in userspace, but it all flows through the kernel to interact with said hardware.

the kernel manages memory,cpu,process management/tasks,i/o,video,etc. at a very low level.

so it is in the kernel where you can affect these things and others which will give an overall system effect in the runtime.
[G Tablet Android Development] pershoot:
this issue should be better/sorted.

yea, that's why it takes you long to boot. all the apps:)
