It's a problem with the XZ compression. Apparently sometimes our touchpad cannot calculate the Checksum correctly and then assumes that it hasn't extracted the kernel correctly, therfore dies.

I am trying to fix this currently. If I have no success we might need to switch back to gzip. (which will make the kernel +1 - +1,5 Megabyte larger)

It's 1728Mhz @ trips kernel. The "2.2Ghz" kernel does not have 266Mhz 2D gpu oc either. It's just ~228Mhz.

Trip knows that. I wonder why he hasn't deleted the post yet.
[TouchPad Development] seth.i.simmons:
Great, good to know youre aware of and working on it. Love the kernel, just wish I could get it to be reliable in booting!
[TouchPad Development] kingtuk1:
I will gladly take a gzip kernel since the latest kernel does not boot at all for me.
[TouchPad Development] mkosem:
Can these devices not boot a bzip2 or lzma image? They're normally smaller than gzipped kernel images. I'm pretty sure I've successfully done bz2 with uboot (but not on an android device).

[TouchPad Development] enik_fox:
I love this kernel just the issues booting and sod's kill it for me. Oddly enough it works fine for a few days lol.
[TouchPad Development] cdzo72:
I have a question for the more experienced...

Is there anything to be gained, or lost for that matter, by using this kernel, but at the same time having supremerohan's tweaks installed and the v6 supercharger scripts installed?

[TouchPad Development] cdzo72:
Dunno if this will help the OP or not... tried to run this again this morning without any luck.

I flashed the latest nightly this morning, 20120404. And then gapps and then I flashed this kernel and it was all good.... BUT when I installed the hacked Maps.apk so that Navigation will work here in Costa Rica, the TP will not boot past where it has the small green Cyanogen logo and says loading beneath it.... BUt, if I boot into moboot, choose Cyanogen Mod as the boot instead of Bricked then it boots fine.

Once I boot again, if I remove the hacked Maps.apk it still wouldn't boot so I did some more tinkering...

I went back and flashed the previous nightly, 20120329 and used the Bricked kernel without gApps and it boots fine, with the new nightly and gApps and Bricked kernel, I couldn't get it to boot no matter what I did, wiping caches, dalvik and factory reset, the whole nine yards
[TouchPad Development] nikos5800:
hello developer are you still working on this kernel?
[TouchPad Development] show-p1984:
I got a lot on my plate atm. I did some rather extensive work on the pyramid, which still needs an aosp version. Then i will come around to the touchpad.
[TouchPad Development] Trainer_H:
How could i delet it out of my bootlist?
[TouchPad Development] mkosem:
Follow the uninstall directions in the OP.

--Matt
[TouchPad Development] Trainer_H:
if i try "rm /boot/uImage.CM_Bricked-Kernel" they mean it is a Read-only file system, so i can't delete this file.
[TouchPad Development] mkosem:
The step immediately before that one remounts boot as rw. Did that step succeed?

Thank you. Please know that your work is very much apreciated by many here in this section, and that we are patiently waiting for the next thing you can cook up for us
[TouchPad Development] tichs:
As far as I am concered to run it at 1.9 is perfectly safe and won't harm your device because the CPU can handle that with ease, if you go above 1.9 let's say 2.0 you can start getting heat, if you go further and heat it up so much it can make silicon damage to the CPU. So the max speed you may want is that because seriously it runs perfect buttery silky smooth. If you want 2.0 or 2.1 use it for benchmarking or a specific task but don't use it much of the time because it heats up and may cause unexpected reboots. But definetly worth it if you really need the speed.
[TouchPad Development] Trainer_H:
if i start "adb shell" they sayed "error: device not found". What should i do?
[TouchPad Development] nitrobg:
Manually install the generic ADB driver located in *\android-sdk-windows\extras\google\usb_driver through device manager.
[TouchPad Development] nixey55:
I installed this kernel and it's great apart from 1 thing

If it goes to sleep when it's on the touchstone it will not wake have to force it to shutdown and reboot.

If it sleeps off the dock it wakes perfectly.

This isn't just a occasional thing it does it every time it's on the dock.
[TouchPad Development] unsivil_audio:
Try it a different kernel version. I had to go back to. V. 65 because of Sod's and wakelock issues.
[TouchPad Development] nikec:
any plans for a new version with the badass governor?
[TouchPad Development] Divine_Madcat:
I would say that this kernel is officially doa.. I wouldn't expect anything new at this point..
[TouchPad Development] show-p1984:
Yes ;)

I just took a bit free time to enjoy the nice weather we had in the past 3 days ;)
[TouchPad Development] nikec:
No problem mate :) The weather is just too beautiful to spend it in front of the screen :)

Anyway, I'm excited about the new version :)
[TouchPad Development] nikos5800:
its that mean new kernel coming soon?are you allready finished with htc sensation/pyramid?
[TouchPad Development] Remolten:
Yeah hoping for update from the dev sometime lol.
[TouchPad Development] sahhar1993:
can any one fix this kernel :-P
[TouchPad Development] Remolten:
It works just doesn't boot easily.
[TouchPad Development] Razor512:
it is a bit buggy.

The GPU overclock significantly improves GPU performance took my quadrant score for the 3d section from 1613, to 2014

but the overall score went down because this kernel for some reason, reduces the CPU score, memory score, and IO score as compared to the stock stuff that comes with cyanogenmod.

if they could take the stock kernel and just apply the GPU overclock then it would be great.

even when I take the max overclock from 1.78GHz to 1.89GHz, on every single benchmarking app, it scores lower than with the stock kernel, the only area where there is a consistent and significant improvement is with the GPU performance

The max stable that I can get is 1.83GHz, 1.89 will cause the system to reboot randomly every few hours (this is because who ever made the kernel, limited to voltage to 1425mv while from my testing with webOS, it needs at least 1487mv

The 0.6 build of this kernel also introduces a lot of boot issues, generally takes 3 to 4 tries for it to boot

does anyone know if there are any cyanogenmod based android builds that just apply a GPU overclock and nothing else as compared to the stock build?
[TouchPad Development] nitrobg:
You shouldn't use this kernel as it is outdated and apparently no longer supported. Stick to the stock CM9 at least until it's updated or a new one is released.
[TouchPad Development] gaww:
While it is outdated, it was interesting to mess around with. But after reading the thread, I am still not sure if there is anyway to get its WiFi working.
[TouchPad Development] fishhelmet:
Everyone should pm show-p, I think he forgot about us.
[TouchPad Development] Razor512:
I wonder are there any guides that focus just on unlocking a GPU overclock with the stock kernel?

Even if the bricked kernel was stable, as it is now, I would not have used it long because it takes the quadrant CPU score down from around 7400 with the stock kernel overclocked to 1.78GHz, to about 6400 or less even with the kernel is used to overclock to 1.89GHz

I also lose about 300 points from the memory score and around 500-600 points from the IO performance all of this is too much of a loss for the boost in GPU performance that I get.

The best of both worlds will be to simply take the GPU overclock and make it part of the stock kernel
[TouchPad Development] nikos5800:
can developer told us if still working on this kernel?

Real life has a way of getting between the things you wanna do and have to do, that's why I had a little kernel dev pause, but I am back since a week as the Sensation kernels show you.

The touchpad is 2nd on my TODO list, the OneX is next up.

Ofcourse, I think if show-p1984 have solved sod issues it will be great, touchpad kernel its very optimized right now and with gpu/CPU overclocking I can't imagine what can be the benchmark result :)
[TouchPad Development] bouncyball:
Why does my TP boot to a white screen when selecting this Kernal? Also, how can I uninstall this? I don't have a great knowledge on this sort of stuff yet. Only just flashed my TP to ICS 4.0.4 tonight so it's all new to me.

Thanks :)
[TouchPad Development] nikos5800:
Because this kernel its to old and it doesn't work with the current cm9 official nightly

Download root explorer go boot folder and delete the ulmage.bricked

And after that reinstall again the custom rom
[TouchPad Development] bouncyball:
Thank you. I'll give it a go tonight
[TouchPad Development] bouncyball:
Is there a free explorer program that'll do the job? Root Explorer is £3.

Thanks
[TouchPad Development] nikos5800:
1)solid explorer

2)es file explorer file manager
[TouchPad Development] Kasten:
Will this kernel be updated to work with the latest cm9 nightly or is there anther kernel anyone would recommend for the HP touchpad?
[TouchPad Development] show-p1984:
yes it will. in the next few weeks.
[TouchPad Development] nikos5800:
And your kernel will can be run on cm9 or cm10 ?
[TouchPad Development] reggiexp:
Tablett lags on briked kernel graphics ****ed you know whites lines

So uninstal is with comande center on windows? If i get it right?

But adb? Do i need that? Install or something because wanted to try this but lags lile hell so want back to cm9 kernel and yeah now no wifi--"

It looks great the kernel but if it wont work its ****...ow okay you gone update that good

Shortly.

(All times are measured in VT)

There will be no ETAs, because I have no idea how much time I will need to fix the reboot issue on the One X. It can be done in 1 hour, or 1 week. But I will not leave a rebooting kernel on a device and move on to the next one.

He starting to working on nexus 7 kernel, i think we must wait much more :(
[TouchPad Development] show-p1984:
The Nexus 7 was donated to me and has the same soc as the OneX, so there is a lot of stuff that is being shared between them. Would you have me tell everyone (especially the one guy that donated over 80% of the N7): "Hey guys, thanks for the N7, but I am off working on my Touchpad. Bye!" ?

That would be unacceptable.

Since I am still working on the OneX too, I wouldn't be working on the Touchpad either.

It takes how long it takes. That is all what I can tell you.
[TouchPad Development] Divine_Madcat:
Well, I guess that will teach me to get my hopes up..

While I understand what you are saying about the donation bit, it is rather disheartening to keep hearing that something is coming, only to be put off for device after device ... I really appreciated the work you did, which is why it is such a bummer to see other devices get love after we had been hoping for so long..
[TouchPad Development] Razor512:
I wonder is it possible to have a kernel that is as close to the stock that comes with CM( but with 1 change being the GPU overclock?

It would be also great to have a wider voltage range to choose from. In webOS, I have been running my touchpad at 1.89GHz + L2 overclock and a voltage of 1600mv for about 1 year, and I use the touchpad daily mainly to surf the web and watch 1080p video while in bed.

at 1400mv, only 1.78GHz is stable and 1.83GHz is not stress test stable but with extra voltage (1500mv+ I can stress test at 1.89GHz with no problem)

in android, some HD videos will have a few stutters when there is a lot of motion (but the CPU will not be at 100% and since the hardware render is used, the limit is most likely the GPU, (if we could just push the GPU to around 333-350MHz HD video should be smoother as well as games )

[TouchPad Development] Razor512:
I was wondering does anyone know what part of the kernel is actually modified for CPU and GPU overclocking and is it possible to just take that one section of changes and just port it over to the stock kernel from cyanogenmod.

bricked kernel makes many changes but for the most part, we only need the CPU and GPU overclocks and while I such at programming, I feel that it would be easier just to focus on those 2 features and leave everything else stock, or if that is too much work, then just port over what is needed for GPU overclocking and leave everything else stock.

Most (if not all) users will be able to get a nice 30% performance boost on their GPU without any stability issues.
[TouchPad Development] mjben:
Am wondering about this also. This kernel seems like it hasn't had a lot of activity recently.

Has anyone flashed this with nightly 1118 and the camera patch?

This kernel is so old its not even funny; the dev abandoned it anyway.

[TouchPad Development] DashingGentleman:
No issues so far that are not present in the default kernel.

Edit: It still does the same thing, every time I rest it on the Touchstone, it keels over. Hrm...

Edit again: It doesn't do it if I lock the tablet prior to resting it on the Touchstone. If I rest the tablet on the Touchstone while not locked, it immediately freezes.

Edit 3: Nevermind, it did it anyway.

Since I do not own a touchstone it would be nice to get some logs.

What clock thingy?
[TouchPad Development] treehumper:
I sent you a log, from nathanbelote@gmail.com.

And there's a desk clock that pops up every time I dock the touchpad in the touchstone.

---------- Post added at 06:00 PM ---------- Previous post was at 05:57 PM ----------

Even more clarification: it works well while *on* the Touchstone, it just locks up after being removed. Very odd, but I can live with it for now as long as it means the Touchpad charges, which it seems is what is happening.
[TouchPad Development] show-p1984:
You don't need to remind me of issuetracker changes, I get them per email ;)

The deskclock is a rom thing and has nothing to do with the kernel.

[TouchPad Development] dirran:
same issue here

I had the same issue coming off my touchstone this morning as well after switching to this kernal. Hadn't happened before on the stock kernal.

When I pulled mine off it wouldn't let me do anything with the screen, or hardware buttons but the desk clock did move once on the screen before it locked completely and rebooted.

Edit: actually I installed Nova launcher last night as well. It could be related to that. I'll try and switch back and test that.
[TouchPad Development] treehumper:
I'm running Trebuchet, but Nova is installed. I can try and remove it...
[TouchPad Development] dirran:
I just switched my default launcher back to Trebuchet but the locking still happened. Not sure if uninstalling would make a difference.

Uninstalling didn't help. I manually deleted every trace of Nova Launcher (I don't like it anyway). I reloaded stock kernel and the problem is gone.

---------- Post added at 11:50 PM ---------- Previous post was at 11:35 PM ----------

Overall I liked your kernel better. Your wifi was a bit stronger as well. I just can't justify leaving it as-is with it locking up when I pull it from the Touchstone, not with kids around here that knock it off or grab it a lot. Your wifi stays up better than stock, that's for damn sure.

And after removing yours, wifi doesn't work.... damn. I'll play with it.

If we change name of kernel file in your brikied zip to uImage.CyanogenMod will it overwrite original CM kernel?
[TouchPad Development] show-p1984:
Yes.

But: the default boot will still be CM_Bricked-Kernel.

You can change that in /kernel/defaultboot.sh

Change:

#!/sbin/sh
echo "CM_Bricked-Kernel" > /boot/moboot.default
return $?

into:

#!/sbin/sh
echo "CyanogenMod" > /boot/moboot.default
return $?

The next versions of this kernel will be smaller in size (thx to XZ compression), so it may not be necessary to delete anything. (depending on your device setup ofc)
[TouchPad Development] lambda30:
@show-p1984:

From what you have told us, the battery life is supposed to be the same as with the CM9 kernel, right ? And what would that be more precisely ? 8 hours like HP's official take with webOS ? Or a little under that, like 7 hours ?

I'm asking this because I have the feeling that my battery life is quite miserable. Something more like under 5 hours. So nowhere near those illusive 8+ hours.

I would really appreciate your response on this matter. Thanks a lot !
[TouchPad Development] show-p1984:
To be honest I have no idea what HP wrote.

My touchpad did last 12 hours with Bricked v0.1, with about 60% screen on time.

I had no chance to get any new data because my touchpad is hooked up to usb for debugging puposes 24/7 atm :p
[TouchPad Development] lambda30:
http://www.engadget.com/2011/06/29/hp-touchpad-review/

Engadget:

"Battery life according to HP is 9 hours for continuous video playback, and in our test (WiFi on, Bluetooth off, video looping) we came close to that: just over eight and a half hours."

So that means 8:30 hours of screen on time with Wi-Fi and Bluetooth on. Probably with 60% brightness.

One comment from an Engadget user:

"I use it ALL day at school for a solid 8 hours with the screen staying on the entire time, and casual internet pages inbetween boring lecture bits. Have not killed it yet. Screen brightness is consistently 50-75% as well."

12 hours with 60% screen on time. You mean 60% of that time the screen was on, or that the screen has accounted for 60% of battery drain ?

If it's the first one, that means you had 7.2 hours of screen on time. That's good. At what % brightness ?
