If you get caught in a boot loop cuz of setCPU, you can delete the settings from ADB to reset setCPU and get out of it. just rm -r com.mhuang.overclock from the /data/data folder.

Worked for me.

Edit: You'll lose your profiles though.

SetCPU also supports the setcpu_safemode file or the .nocpu file in /data/local, /data, and /sdcard. As long as any of these files exist, it won't boot loop you.

Wifi only Xoom.

I have been running 1.4.4 for a few days. I flashed the CWM 3.2 .zip from recovery this morning. Now I can't cold boot into bootloader or recovery anymore. Volume up + power just boots normally. Everything else is working fine.

Just put this on my uk xoom. Took ages

Had to root and install cwm first.

tried a one click root and it just bricked found another way and it was just dandy.

Main reason I wanted it was for USB otg mounting of pendrives.

But have oc'ed it to 1.5 just to show off lol.

Very impressed wth it. Well done.

I flashed to 1.4.4 and just about everything works great at 1.6 ghz. The one issue I have is that when my screen shuts off it seems to drop my wireless connection to my router after a few minutes. It isn't the end of the world, but once I turn the screen back on my Xoom takes a few seconds to connect the wireless router again and then catch up on any data that it hadn't received (chats, emails and the like). Anyone else notice this? This never used to happen on stock.

@1.7 its no good in my XOOM WiFi... reboots just after setting the speed. (no sure if the problem may be just the vsel kernel settings... actually, I'm using the OC GPU version)

trying @1.6 now... had to use a bit more to know if it's really stable (had a reboot at this speed in previous version while remoting my desktop (with 1920x1080 display with Pocket Cloud)...

Anyone else on wi-fi only Xoom lose their wi-fi after flashing 1.4.4? On the settings screen Wi-Fi says "Error", and I cannot connect. This is the first version of Tiamat to do this to me (and I've flashed them all so far!). So I am confused. :confused:

Edit: Just flashed back to 1.4.2 @ 1.6GHz and it seems fine... wi-fi is back. Also getting much higher quadrant scores (4210!)
[Xoom Android Development] JFMFT:
Re-download 1.4.4 and re-flash. It may fix your Error on Wi-Fi.

In not sure ive really seen any tangible everyday performance gain from this kernel. I run at 1200 most of the time, but the governors ar just too slow. An ipad 2 unfortunately still feels so silky smooth picking up scroll events and the like.

I have used my xoom extensively and heavy widgets dont make too much difference. Its the animations that are the problem, even now at 3.0

How do you see no real world gain? why not run interactive @ 1600. Also look at the ipda2 homescreen. Its simple scroll left and right. Install ADW Launcher on your xoom and it will run smooth as butter.

Got a question, I read on Peter Alfonso, the author of bugless beast ROM that in his kernels, he is using some tweaks to speed up SDCard access, some .35 kernel tweaks and also using the .38 kernel "interactive" governor code which is supposedly more advanced than what's in the earlier kernel versions, does the kernel here use the .38 kernel governor code?

Are you using SetCPU?

If you look at post #1004 in this thread, some one had "flickering" camera problems after flashing. It seems that once SetCPU was disabled, the problem was solved.
[Xoom Android Development] ClydeB1:
I think you misquoted me instead of @intensus LOL, but to answer your question anyway, No I'm using No-Frills CPU now, but was using SetCPU and my front camera has always worked and still does :D

[Xoom Android Development] ClydeB1:
No problem, I know those few quick sneaked replies at work LOL.

Not sure what the problem could be re the camera to really help @intensus. As it's not the kernel it is possibly an app or just a hardware issue.

Nevertheless, I WAS experiencing problems with my xoom after flashing the newest tiamat kernel and it would randomly reboot and act up at times (froze twice a well). IT seems quite stable at 1.5 now, don't think I'm going to push it to 1.7 though.

Thanks guys.

Testing

So I was finally able to test both versions of 1.44. Here are my results.

When running 1.44 with the OC GPU I would get repeatable reboot when running at 1.7 and 1.6 GHZ. It was only when I dropped it to 1.5 GHZ that I was able to use my Xoom. I then loaded 1.44 without the OC GPU. I was not able to run at 1.7 GHZ but I was able to run at 1.6 GHZ with stability.

I am going to be interested to see how this kernel develops. I am going to now try the other kernel developer's kernel to see how it differs from this.

Steve
[Xoom Android Development] willverduzco:
That's quite interesting to hear. I'll have to try this out on my own as well, as I can only run at 1.5 GHz and I only use the GPUOC version. That said, the limiting factor in our game performance is GPU, not CPU. I will happy accept this trade-off. :P
[Xoom Android Development] PMDColeslaw:
What should i be using to adjust the clock speed? I flashed the boot and kernel yesterday. Do I need to dl setcpu or something?
[Xoom Android Development] stevefxp:
SetCPU is what I use.
[Xoom Android Development] stevefxp:
I ran with the Launchpad kernel and I am able to run at 1.7 GHZ with no reboots or hangs whatsoever. There must be something different in the kernel implementations between BRD and Launchpad. I would love to know what it is.

Next on my testing hit parade is to run Quadrant against both. Granted I do not put much stock in Quadrant as a performance tool but it does give me a graphical representation. If you have any other suggestions for test tools I would love to hear about them.

Steve
[Xoom Android Development] ClydeB1:
AFAIK the difference between the 2 is in the voltage settings. I know BRD has stated that he is trying to implement voltage settings into his next release.

@bigrushdog, any chance of an update to the boot.img for 3G Lights on. I tried the current version with your new rom and although the LED lights up while charging, it seems to cause a wi-fi error.
[Xoom Android Development] stevefxp:
So does that mean Launchpad is using higher voltages to keep stability, even at 1.7 GHZ? Its too bad the voltage settings are in hardware on the Tegra. I would love to use Viperboy's mod to control voltages, much like I do on my Incredible. With these changes I can get about 1.5 days worth of life before a re-charge, whereas before I was barely able to make it a full day. Imagine what we can get on a Xoom!

Steve
[Xoom Android Development] ClydeB1:
AFAIK, yes. You can get more info re Launchpad and the over/undervolting settings here - http://www.xoomforums.com/forum/mot...hpad-1-2-1-new-6-8-11-3-1-only.html#post69562

[Xoom Android Development] stevefxp:
It locks up at 1.7 GHZ for me now, so it looks like my Xoom does not like either kernel at 1.7 GHZ. I am back to Tiamat now. Oh by the way not sure if anyone has used pimp my CPU but it errors out on my Xoom.

There is a memory leak issue in TIAMAT Kernel. The free memory will decrease slowly. After 1-2 days using, even if I killed all process, the free memory will be below 150M, I have to reboot xoom to free memory.

But Launchpad Kernel is very safe, free memory is always larger than 450M after I killed all process. So maybe there are something wrong in TIAMAT kernel.

BTW:The memory leak issue didn't exist in 1.3.2. It's in Kernel above version 1.4.0.
[Xoom Android Development] bigrushdog:

I am profoundly grateful to you, our hero.

Using red font is to catching your attention.

I reported the similar issue on this post: http://xdaforums.com/showpost.php?p=13308325&postcount=1419. But it is flooded by so many posts.

The leak issue exists in 1.4.0 is about tethering. While the issue in 1.4.4 exists in normal using.

To those who impeach my motives, I mentioned LaunchPad because I wasn't sure the issue was coming from the ROM or the Kernel, until I flashed LaunchPad kernel.

Here is my test in the past few hours.

I observed that if I cut off data connection, there should be no issue.

After I turn on WiFi or 3G network, the free memory began to decrease.

1.reboot xoom, and check the free memory. It's 429M.

2.Turn on WiFi, the free memory began to decrease.

3.after about 3.5 hours, the free memory decreased about 40M.

4.Still decrease slowly.

I'm having a problem with this kernel and was wondering if anyone can help? I can't seem to detect any of my connected FAT32 thumb drives or my Sony Cyber-shot camera. I am using a UK Wifi Xoom rooted and patched to 3.1 with the latest version of this Kernel installed and also the USB Mass Storage Watcher OTG app.

When I plug in a USB thumb drive into my OTG cable it doesn't detect anything is plugged into it (using estrongs File Explorer to look in the usbOTG folder) and the light on the USB drive doesn't come on either , also when I go into the USB Mass Storage Watcher OTG app it says that there is No USB Connection. However I can get the Xoom's SD Card to show up on my PC using the USB Mass Storage Watcher OTG app. So this seems to rule out that the OTG cable is faulty.

I have tried connecting the thumb drives with USB debugging switched on and off, I've also tried rebooting the Xoom with the drives plugged in but have had no success.

Any help really appreciated as I cannot for the life of me figure out what I'm doing wrong.
