Yep. He means that :)

Pretty much 1000 should be fine (that's the rated speed) and 1200 should be fine, and 1400 depends on your karma :)

Uncheck the "set at boot" option in setcpu. That way, it will reset to a stable speed if you need to reboot/it freezes up. Once you find your stable max, you can set it at boot safely.

I need to update to yesterday's kernel, but the one before that was rock solid for me (on CM7 nightly 41) at 1200, but not stable at 1400. So I run it at 1200. Even "just" at 20% overclocked you can really feel the difference.
[G Tablet Android Development] cotangent05:
oh i get it... :) i thought 1400 will be the stable clock for everyone.. :DD thanks that lightens things up.. by the way @pershoot, your kernel rock! \m/ thanks
[G Tablet Android Development] pershoot:
this looks good so far (04/20).

that 'stuck' feeling in certain apps during access looks to be further diminished.

will look in to the timing issue when un-mounting USB and overclocked past 1000.
[G Tablet Android Development] brew1brew:
Pershoot, I have a couple of quick questions,

1. you say "In order for UMS (USB mount) to work on Gingerbread, this must be reverted:" so do I have to recompile this option out to have USB mount work on CM 7.0? (gtab) or did you already do that in the Gingerbread version? and is this to mound a USB stick on the device or have the devices SD mount on a computer?

2. can I set CPU speed in CM 7 with the settings option under CM performance?

3. USB networking, does CM 7 have the necessary components to go with your added kernel functions?

Thanks for the hard work

I updated to this on a gTablet/CM7 nightly 41 / OC 1200, running good. Did notice lag (rarely) on the previous version, none at all on this one.
[G Tablet Android Development] pershoot:
1. this would depend on the rom your running. if running cm7 or the latest vegan gb, you can disregard this.

2. this doesn't work currently. it's on the list to fixup.

3. it should work. pls test it and let us know.

Thank you pershoot ;)

btw, how are you stress testing your overclocked gtabs guy ?
[G Tablet Android Development] schettj:
Running benchmarks, if it doesn't just roll over and die :)
[G Tablet Android Development] rob_z11:
Well, it is not fair test since you are running custom kernel with higher clock rate.. Have the ROM of your choice, but use the default kernel without customizing the kernel to see how Viewsonic does against the Asus.
[G Tablet Android Development] Dueces99:
That would be the fair way to do it, but why do that after all the work thats put into these kernels?? Gotta show em off somehow! Also, thanx aasoror for the comprehensive list of benchmark apps. Some of those I never heard of, and like to have butt loads of data from benchmarking, gonna have to look into those!
[G Tablet Android Development] brew1brew:
Thanks man!

[G Tablet Android Development] pershoot:
how's 4/20 working out?

smoother then previous?

responsive?

etc.?
[G Tablet Android Development] wd5gnr:
So far great! Thanks man! Not sure I can tell much difference casually but over the non oc it screams. Hoping this one will wake better than previous ones. Seems to not wake well from out of the bag but haven't seen that on the latest so far.
[G Tablet Android Development] pershoot:
i increased voltage to the low end. those devices (such as yours) which were starving/struggling at sleep, should be sorted now.
[G Tablet Android Development] aasoror:
Why would using any other firmware but stock be any fairer than using nonstock kernel ? some of these roms have tweaks and code optimization that would also bias the results from a stock ROM. For the end user, the overclocking kernel is just as installable as the custom roms (both involves several clicks from CWM, reboot the device and enjoy).

Exactly, overclocked numbers are fair and square because :

- overclocking is running invisible to the end user with minimal effect on battery life and system stability.

- you are not comparing stock to stock (and you shouldn't), you should be comparing the best you can get from each tablet (else it would be unfair to make any comparison involving a nook, for example, unless it has the B&N stock e-reader only firmware).

- until a stable overclocking kernel is realized for the Eee pad this is a fair and accurate status quo.

- there is more into overclocking than just CPU right ? (which is common between GTab and Eee pad) lots of other components and build quality is involved to maintain stability at the overclocked speeds, so what if a stable overclocking is not achievable on the Eee pad, for whatever reason, would that invalidated the results reported above ?! I would say no. Wouldn't that make it an inferior product ? I would say yes. Not fair ? well, perhaps but most of us aren't looking for fairness but more interested into the best bang for buck ;)

no problem :), that said I didn't do much, I just followed laptopmag lead.

[G Tablet Android Development] chugger93:
Can someone explain what these modules do? Why to install them, etc?
[G Tablet Android Development] tcrews:
Basically...if you have to ask, you do NOT need them :)

However, to answer your question...they add additional features if you need them like CIFs support, NTFS support and others... I only use the CIFS.ko to map shares on my NAS box, so that's the only module I copied over and use.

Chugger,

Nothing which would affect your usb drive has changed from 4/20 to 4/19.

Reflash up and post logs if u still face issue.
[G Tablet Android Development] chugger93:
Well what else I noticed is this. Originally my flash drive was formatted as fat32 and it was working. I decided to format to NTFS on it because it wouldn't let me copy a 7GB mkv movie to it. I'm assuming because of fat32 limitations. Once I formatted as NTFS, I could copy the file to it.

However now, it won't read the flash drive again...and maybe its cuz of the NTFS formatting.
[G Tablet Android Development] pershoot:
U have to push the ntfs module from lib pack to your system and insmod it.

Then mount your usb drive's partition.
[G Tablet Android Development] chugger93:
I was gonna say, that sounded familiar. Plus I was trying to follow this guide pershoot:

http://xdaforums.com/showthread.php?t=1028285

So maybe pushing the NTFS module should help that situation out huh?

Oh and just to reiterate, it's the nfs.ko module right?

Thanks man! Appreciate all your responses and insight
[G Tablet Android Development] pershoot:
once you load the NTFS module, you will be able to mount your NTFS partition.

ntfs.ko
[G Tablet Android Development] chugger93:
n/m, may have figured it out
[G Tablet Android Development] pershoot:
put it under modules. that folder is under modules (it gets flashed when you flash the .zip).

your adb is messed up. disco and reco, make sure debugging is on.

do it in recovery if anything.

scan this thread, there is instructions.
[G Tablet Android Development] chugger93:
pershoot: naw the error was cuz my tab was going to sleep and I was loosing my wireless adb connect. I'm good, and it worked! I can now mount my ntfs flash drive. Friggin brilliant!

Thanks so much for your help. b.t.w, will I have to do this ko module push everytime I flash a new updated kernel of yours?
[G Tablet Android Development] pershoot:
only when the version changes in the kernel and/or there are updates to the module.
[G Tablet Android Development] chugger93:
weird, now even fat32 stopped mounting. can't get it to work anymore. Before your other post I pushed the nfs.ko module not realizing it wasn't ntfs.ko, but I just left it there. I doubt that had any implications
[G Tablet Android Development] pershoot:
start from scratch and go slow, and you will sort it.
[G Tablet Android Development] chugger93:
Reflashed 20th kernel, did the push of the ntfs.ko, still nothing. Ok' either I'm an idiot, or something is jacked.

I'm gonna keep tryin tho...cuz I did have it at one point.

Do I have to get adb loaded on my tablet somehow?

Or can you not do it this way, and I have to use adb from my laptop...?

EDIT: Sorry, I didn't need the adb shell part in there I guess, cuz it worked now... when I insmod it, everytime I can get it to mount now. Good stuff

just updated to the latest kernel (cleared dalvik and cache) now any app i launch just closes and goes back to the home screen.

vegan 5.1.1
[G Tablet Android Development] pershoot:
Why are you clearing cache before kernel flash? your flash went haywire.

Reflash the rom (clear dalvik first). Then flash kernel. Then reboot.

There is no need to clr cache b4 kernel. As a result your dalvik may not have repopulated properly.
[G Tablet Android Development] davidukfl:
never mind it's working fine now. I guess it just needed a bit to get itself together.

Usually i clear cache and then dalvik cache after i flash the kernel. I didn't realize that was the wrong order.

thanks for clarifying for me though :cool:
[G Tablet Android Development] Vadimus_ca:

So clear cache, (only cache or all?), reflash rom, immediately after rom can I flash the kernel at the same time or do I need to reboot first?
[G Tablet Android Development] pershoot:
only cache (dalvik), from wipe menu.

then flash rom, flash kernel (GB = boot-cm_2632.39_gb-oc-uv-xtra-vfp_fp-042211.zip, froyo = boot-cm_2632.39-oc-uv-xtra-vfp_fp-042211.zip), then reboot.

gb has HW video decoding now for harmony. SW AAC is still being used though.

flash the latest nightly.

Ok so I posted about that when I read the changelogs, yet I noticed it was only a change to the framework and it had me thinking it was only support for the nvidia stagefright stuff when it would arrive. I did see that aac software decoding too... I'd love it to have ac3 soft decode. Rockplayer has that, yet its only for sotftware mode, which means sw vid dec as well.
