flash the latest kernel (2.6.32.38).

after boot, type:

dmesg | grep CPU | grep clock

dmesg | grep CPU | grep -i nvrm

paste that output here.

then go to setcpu -> device selection -> custom

you should see max: 1400, min: 216 (your previous values wil be retained which you had when you last opened it).

select max: 1000

run smartbench 2011 three times in succession

max: 1200

run smartbench 2011 three times in succession

max: 1400

run smartbench 2011 three times in succession

you will see an increase.

paste the 3rd run number here from each clock (1000,1200,1400).

For me, the number one issue is the reset on start problem. If I cannot stop and sleep the pad, and then pick it up later, and resume my work, it's little more than an expensive gameboy.

Which is better?

Just wondering which one is better for the every day user. 2.6.32.27 or 2.6.32.28. Does either one have automatic mounting of an NTFS file system? Also just saw that there is now a new kernel for my G2 on droidbasement. I must say pershoot I have been using your G2 kernels since you started making them and they are all very very impressive. Can't wait to see what you can do with the Gtab. Thanks for all your hard work.
[G Tablet Android Development] pershoot:
use the most current kernel offering to date (when possible). in this scenario, it being -010911.

i posted instructions on how to automate NTFS. scroll up. either through an init script (with a delay) and/or a gscript.

I like to think it's Master Control from Tron.:D
[G Tablet Android Development] wd5gnr:
Well I fired up DDMS (actually, although I don't build kernels for Android I do a lot of low level coding in real life ;-) ) and I found that every time I boot it is unpacking native libs for practically EVERY app.

I don't think that's normal. I have a feeling it has something to do with reloading apps via Titanium Backup and not getting them in packages.xml. I'm trying something now that should either a) prove that, b) disprove that, c) let the smoke out of all the electrons.
[G Tablet Android Development] Synman:
Unpacking or loading? Anything that reaches beyond the jvm will call upon its underlying native library via jni. Opengl, video, audio, etc.... all jni. Just like vanilla Java the google vm is a slow inefficient pcode dawg.
[G Tablet Android Development] Synman:
Still getting a consistent 4300+ smartbench score with the new version. Wake is smooth too.
[G Tablet Android Development] wd5gnr:
On first boot, the system will run dexopt to try to build a cache of JIT compilation and other things. But there is also an install step that unpacks native libraries (by the way, I have become fond of JNA over JNI, and was sorry to see its not well supported on Android). I am not sure why it is doing this install step on each boot.

I'm not a big Java cheerleader but its good for what it is good at and getting better all the time. Froyo and beyond actually use JIT if I'm not mistaken. And the DEX format is much tighter than conventional class files.
[G Tablet Android Development] Synman:
For some reason (lack of reading comprehension on my part) I thought you were referring to app loads.... not boot up.

IRL I play a similar gig development wise it sounds.

Thanks for the awesome work.

one more thing, in the instructions its mentioned that its better not to use any of the governors listed (performance, power saving), but I noticed that once you pick one you are no longer able to "not chose any", am I missing something ?

Running CM7 (nightly #39)

Thanks in advance,
[G Tablet Android Development] pershoot:
yes, you should not pick one at all. there is no need, in the way things are setup currently, in the kernel. just reboot so it goes out of effect.

ill probably take those out from being seen for the future.

Everything is working great! Just outta curiosity, any reason why your kernel OCs to 1.4 where clemsyns goes to 1.5? Is it something related to the ROM, or just a personal preference? Either way, phenomenal work!
[G Tablet Android Development] pershoot:
because 1.5 will not be stable/feasable for the masses, within the confines of how much voltage i am willing to give and while keeping within the limits of what's allowed, etc., etc.
[G Tablet Android Development] adampdx:
I've been wondering this myself. So if we really wanted to push this thing, like almost to guaranteed burnout, what's the theoretical maximum clock speed the kernel can enable?
[G Tablet Android Development] wd5gnr:
Looks good here. Last night I repeated my sleep experiment. 6 hours later it was still asleep and battery went from 85% to 78% so that's didn't strike me as unusual.

Just to jump in a little here. My Droid 1 isnt stable past 1Ghz however my wifes runs just fine at 1.2 Ghz. From watching people test pershoots kernels on irc anything over 1.4 was just not stable for everyone. I think pershoot wants stability for the masses while pushing the envelope.

Right, my first impression was that it was related to instability. I'm overclocking my pc around the clock (cpu, ram, video), and stability obviously plays a role in what you can safely run. Thanx for the input!

Flash playback and video?

I know we don't have HW acceleration yet, but does this help with the transitions in video (i.e.e Youtube app) to smooth them out and make that sort of video a bit more watchable? Running CM7 stable.
[G Tablet Android Development] Oozura:
just saw the reason. I was too optimistically trying to load the g2 1.5 kernel. Doh...
[G Tablet Android Development] pershoot:
yes.

sorry i missed over the filename in your posting just now (just scanned my eye over the last line with the error).

the gtab kernel filename has a vfp_fp in it.
[G Tablet Android Development] pershoot:
double post...
[G Tablet Android Development] wd5gnr:
Silly question: is it because its the neon and not the vfp? I assume that's a kernel using the ARM NEON instructions which I think we don't have.

Whoops I was typing while Pershoot was hitting the post button. Whoops.
[G Tablet Android Development] pershoot:
that kernel is for a completly different device. it will never work/boot on this device.

at any rate,

we (tegra2) dont have neon. only vfp3(-d16).

scorpion has neon.
[G Tablet Android Development] wd5gnr:
Yeah. I do some ARM stuff on the side -- guess I will eventually go grab the Tegra tools and tear us some stuff ;-)

By the way, I had the speed shift problem again where I unplugged from AC and appeared to be stuck at 1400MHz. Turns out it is just the SetCPU widget that is stuck. Opening the app showed the limit was set right and the speed was changing. But the widget was frozen (I have it on a reasonably fast update rate for the moment, like 30 seconds or maybe less just for troubleshooting).

So I think that was probably the same case before I just didn't investigate.
[G Tablet Android Development] pershoot:
yea.

Thanks for all the hard work!

Just curious if you've given any thought to adding the hfsplus module to it. I just checked the modules and didn't see it, but I know you had said previously you would consider it. I have an external drive that I take on trips with me, but is most often connected to my airport extreme at home. So hfsplus is the best format for it. Would love to be able to watch videos off it when I'm traveling though :)...

Or can you point me to a descent howto for building kernels for android. I used to build them back in my gentoo days, but its been a while, and I know I don't have a crosscompiler currently installed.

Either way, thanks!

you had a bad flash.

nothing which would prevent you from booting was in the refresh.

try again.

for a full sweep, clear dalvik (from wipe menu), reflash rom and then reflash the last kernel which was not oc'd. reboot.

boot in, reboot back to recovery, flash the latest oc kernel, reboot.

i see your using calkulin. please do not reflash with the oc combo of that rom (if you were attempting to use that prior). keep things clean and use the stock (non oc) rom that was given by him and/or clem.

[G Tablet Android Development] Blades:
Is there a defined switching time for clk/vdd? What gets there first in the event of a clock speed change? Desired voltage or desired clock? Is it upclock/downclock dependent? You may remember me mentioning something similar that exists (upclock/downclock independent) for dz/g2 board-power src.

Since this implementation is a manipulation of a daemon/driver that controls clock speeds, I'm guessing that vdd/clk logic is already in place - in a good way. Correct me if I'm wrong on any of that. It would be nice to have some control, having the vdd be set (reached) further ahead of the clock on an upclock event could help with stability issues.
