Honest, I was going to say Wifi is worse. In other words no different ;-)

With respect to battery life I don't think there is any issue with the kernel. But turning off background sync on applications will make a huge difference. I believe in general apps try to sync and fail because Wifi don't connect in time, thus waste energy. Only a theory.

With Clemsyn's kernel and CIFS I was able to copy over 10 GB of data to sdcard2 without a freeze. That's a first. So I would suggest one of the patches applied by Clemsyn in fact fixed an outstanding problem.

On the other hand I have seen some strange video corruption, but I don't know if that is related to the kernel or the phase of the moon. I need more time to play and I'll get to it tonight on a long plane ride.

One more thing... I changed the optimization on the kernel build to "-O3" and the quadrant score seemed to bump up a little. I might be worth testing this on a kernel build.
[G Tablet Android Development] rcgabriel:
BTW Clemsyn, NVidia just tagged the 10.9.8 branch on the kernel source code a few hours ago. Doesn't look like any significant changes from 10.9.7 (they added an Atmel Maxtouch driver to the Tegra 2 mainline, but that's not the same as our AT168 driver, and made one or two changes that also don't look like they affect us).

Of course, there are also the 10.11.x tags too, but that's all 2.6.36 kernel stuff I think...
[G Tablet Android Development] rcgabriel:
Good observations vsc.

Not sure about the battery life issue, but I agree that there's plenty to be gained from fixing user space behavior in our ROMs - I see way too much stuff causing wake-ups in my dmesg logs still (and causing the dread error -16 and -11 in there that used to cause lag-on-wake, though that's been fixed). Though I think our active-usage battery life is fine, I think there's a lot of improvement possible in battery usage when idle/suspended.

I have also seen some *very* minor resurgence of the video corruption stuff from time to time since moving to Clemsyn's kernel. I can't even honestly swear to you that it's something in 10.9.7 causing it, but I don't *think* it was present in the stock kernel, nor in our lagfixed 10.8.2 kernels. At least, not with the most recent set of performance pack drivers (i.e. Vegan beta 5, TNT Lite 3.1.x, etc.). It was present, and much worse, in the first performance pack release, as I recall. But that was a driver issue strictly. Since the video drivers haven't changed since the other day, I'm assuming this is some very minor interaction between the kernel and the drivers.

I can likewise stream DVD res movies without issue over CIFS. In particular, I noticed that CIFS mounting works much faster than it did with 10.8.2+CIFS kernels, which took a minute to mount.

Regarding -O3, my understanding is that doing that isn't always the best idea with kernel compiles, though I understand this is an issue of some contention (does -O3 make assumptions about register usage that are true with the vast majority of apps but perhaps not true in the kernel? Is the loop unrolling and the like that it does necessarily good in a kernel environment?). But I definitely believe there could be a 5%+ boost in kernel performance with it. Good find - let us know if things seems fully stable with the -O3 optimizations.
[G Tablet Android Development] ckelly33:
Just finished reading through this and alot was Greek to me. What is TUN Support?

I understand what CIFS is for is that (and TUN) the only difference between the two VEGAN builds on p1?

Still not sure whether I need to install this. I was sold when people mention quickeness and Wi-Fi connect on wake, but later entries show others are still having issues with Wi-Fi disappearing on sleep->wake. Another concern is the video corruption. This might be an issue for me since initially it was bought to replace an Archos video player. Is this corruption somply on streaming (won't use CIFS much) OR does it affect vdieos on device/SDCard too?

question about kernel upgrade

My kernel is 2.6.32-dirty....can I safely upgrade to your latest kernel? If so are there instructions. Posted somewhere? I am running he newest vegan rom. .

thanks
[G Tablet Android Development] rogersranch:
TUN is a kernel module that allows you to use VPN applications to connect to your corporate network or home office.
[G Tablet Android Development] vsc:
Loop unrolling is best for math and such. So I agree in general. But nothing hurts to benchmark it.

I'm getting very long standby times. Playing video seems to be on par with 8-10 hours.
[G Tablet Android Development] digger44:
cifs died

Was using cifs with TNT 10.9.7 kernel perfectly yesterday. Streaming movies & everything... (TNT Lite 3.1.4)

Home from work today and no matter what, I get "Mount: Out of Memory" errors. I tried resetting permissions (no go), un-installing and re-installing cifsmanager (no go), formatting boot and re-loading kernel (no go). I'm certainly not out of memory or card space.

I did search, and in other threads (not in gtab area) someone said un-installing and re-installing fixed it. Someone else said they fixed it without mentioning how!

....don't know what else to try.... something from the terminal? Any other suggestions?

thx

**UPDATE**

I was able to resolve the issue by re-starting the server that is hosting the shares. Even though I was able to access the shares from my desktop machine, it was not allowing the cifs client to make the connection. I think it was responding with an error 12, which according to some links I tracked down tells the client that the server has insufficient memory process the request. So the prob was not with the kernel or the g-tab or my updating skills, but with another machine... GOOD! ;)
[G Tablet Android Development] jaybob413:
I merged in the non-touchscreen 10.9.8 commits, as the comment on one was to revert a previous commit that "resulted in display corruption". With that and the other non-touchscreen changes, I am back to 2400+ quadrant scores fwiw.
[G Tablet Android Development] rcgabriel:
Ah, I shoulda read those patches more carefully. Looks like maybe they fixed a few things after all. Cool beans.

[G Tablet Android Development] bittrix:
This install does indeed put in the new kernel. Ignore the assert error message - it comes up because the installer script wants to continue installing other stuff too, but that stuff isn't part of this package. If Clem is ignoring his kids on our behalf, I'd rather that time be used building kernels rather than wrestling with installer scripts.

The higher "dirty" numbers make me feel, well, dirtier. :D

i installed this and didnt see any difference? except skype didnt work anymore..

whats this kernel doing? i see lots of tla's being thrown around, but i for one dont know what they mean! lol..

so, is there any advantage to the average person installing this? im not running it anymore because skype is one of the things i use my tab for.

what am i missing? people seem excited about this, but i cant figure out why?
[G Tablet Android Development] bittrix:
These kernels are not for the average person. These kernels are for exceptional people only. They are based off the very latest available codebase, contain features not generally available, and, like a hand-built airframe, should be considered somewhat experimental even though they're built with great skill and attention to detail.

[Req] PL2303 inclusion

Hi Clemsyn, I think I'm on to something with the locationprovider stuff. The Vegan 9.8 build is running practically perfect for me - wifi wakes up by itself (at least it was today - knock on wood). Would it be possible to include the pl2303 module again in a future build?
[G Tablet Android Development] vectorcharlie:
Skype faulty

Indeed... Skype is not working for me as well... Someone else with this failure?
[G Tablet Android Development] clemsyn:
Do you want it as a module or you want it incorporated in the kernel? LMK.
[G Tablet Android Development] clemsyn:
I'll reverse the ALSA changes in the kernel and see if that helps skype.

GOT IT!!!! FIXED SKYPE NOW!!

Not related to the ALSA, but disabling NTFS debug fixed it...Will return ALSA Changes and make some kernel with PL2303 module support.
[G Tablet Android Development] clemsyn:
Kernel updates for zpad build coming soon :)
[G Tablet Android Development] bittrix:
Probably a module as long as I can insmod or kmod it before the usb bus inits... that way it doesn't bloat the standard build. {One less thing to break} :D
[G Tablet Android Development] clemsyn:
OK, will make one, update me on how it goes, pls.
[G Tablet Android Development] bittrix:
You're a machine!!
[G Tablet Android Development] pqrs:
thats a nice response... called me average and not exceptional.. lol.. ive installed many kernels, im just wondering what this one does thats useful? some give a lag fix, some overclock, some have better modems.. whats this one got?

just exceptional stuff? un-nameable, exceptional stuff?

are you saying that this does nothing 99% of the g tab owners can use?
[G Tablet Android Development] anlog:
The stock kernel in Vegan b5.1 includes the lagfix and has most of the video artifacts fixed.

There are several individuals putting together custom kernels with various other modifications. The ones here in this thread include CIFS (Windows file sharing), NTFS filesystem support, the latest patches/optimizations from NVIDIA (hard to say exactly what those are), TUN (VPN) support, and other fixes. The are from the latest source tree, and should be considered bleeding edge.

I use them and they work fine, but if you don't need any of the extra features then you should just stick with the stock kernel. The most important and tested features will most likely be pulled into the next Vegan release.

Also, I am exceptional and awesome.
[G Tablet Android Development] clemsyn:
All builds for TNT, Vegan, Zpad 10.9.8 uploaded and has Pl2303 module, CIFFS, TUN and NTFS support.

Re: PPPD, PPP is already enabled. Do I need to enable all other options under PPP to turn PPPD on? LMK and I'll build it.
[G Tablet Android Development] pqrs:
thanks for the explanation, you da man! latest nvidia patches will benefit everyone id have to assume? id love to get some file sharing going on my network too.. so maybe this is useful to me.

like i said, all i could notice was that skype didnt work.. could notice any real differences on the surface.

but now that skype is fixed ill give it another try!

thank you... you are exceptional!:D

[G Tablet Android Development] rushless:
Seems overclocking a dual core will probably have quick diminished returns in relation to correlation of performance and battery usage.

Tegra 2 and OCing seems a rather slippery slope. Not to mention it is passively cooled.
[G Tablet Android Development] geo_gecko:
Skype fixed?

Is the ClempatchTNT10.9.8 kernel the one with Skype fixed? If so, I've done a clean install of TNTLite 3.1.4 with that kernel and Skype still hangs at login. And a NTFS formatted external drive that was recognized using the previous kernel is not seen now. Any ideas?

OK, so no really plug & play process so no point unless you need files from a drive. Not practical for quick access to media. To me at least. I thought true NTFS playback with Android was too good to be true. If it were not, we would already see it supported in general.

All,

I loaded the Clempatch TNT version 10.9.8 on my "stock" 3452 tablet with the enhancement pack.

It shows Kernel Version 2.6.32.9-00001-g6e47897-dirty clemsyn@clemsyn-MM061 #53. No 10.9.8 showing anywhere on page. Will try to check other ways.

Seems to be working fine so far. 2301 on Quadrant, which is down about 100 from the "Stock" enhanced speed.

[EVO 4G Q&A, Help & Troubleshooting] hmsheen10:
Ok i am not really a noob but have never had to update my radios before. Now the new ones are out and I would like to take advantage of them. The problem is I keep hearing horror stories about flashing radios. What do I do if it doesnt work or something goes wrong? IF something goes wrong am I basically screwed? Also, is it ok if I just update the Radios and NV? I don't want to update WiMax because I dont want to lose 4g and I dont want to update the PRI because I keep hearing people are having problems with 100% wake. Also obviously I'm not going to update Hboot because mine is fine.
[EVO 4G Q&A, Help & Troubleshooting] mroneeyedboh:
Basically if your radios are alright I wouldnt flash over them. The main one you reall dont want to flash over is the WiMAX becasue you can loose your RSA keys. If you ARE going to flash over it, make sure you dot he backing up of them. So do an Amon_RA nand and then manually back up you certificate and RSA keys using the guide found in I think the Dev section. And yeah if something goes wrong you'll loose your RSA keys and that will render you 4g dead. And at this time we dont have a way to get the key back in action.

What version ROM are you on? if your on 3.30 then flash and or keep the 1.77 PRI, if you're on a 3.70 rom then flash the 1.90
[EVO 4G Q&A, Help & Troubleshooting] hmsheen10:
Right now I am running BurntDroid which is based off of 3.70 but I change roms ALL the time. I usually stick to AOSP roms though rarely do I run sense roms. Should I update the radio though if I want to stick with this? I have the last version of everything (PRI, Radio, etc)
[EVO 4G Q&A, Help & Troubleshooting] mroneeyedboh:
I would do a nand with Amon RA to back up your WiMAX partition. And then I would manually do the RSA keys and certificate.

But yeah 3.70 roms use the 1.90 so you'll be ok in regards to that.
[Galaxy Tab General] ianandamy:
Ok here is a simple tutorial for any new to this tab stuff like I was yesterday.

I take no credit for this just wanted to help compile an easy solution.

It is so simple once you figure it out.

First download Odin v1.7 here unzip it and stick it on your desktop,

http://xdaforums.com/attachment.php?attachmentid=478059&d=1293895557

Then download these files.

http://files.deodexed.com/ModADroid-Galaxy-Tablet/Rotohammer/JME/

These zips need to be unpackaged to get to the .tar files. Pay attention as Winrar will see .tar as a .zip too. (read the file extensions or you can't select them in Odin.) Stick the 3 files (pit, modem,FmInsSD) into a folder on your desktop. (You no longer use the "Jme-hidden" file shown in the pic.)

Attach your tab to your computer, if you have windows 7 the drivers will be installed for you. If you don't you'll need to get them from here.

http://downloadcenter.samsung.com/c...G_USB_Driver_for_Mobile_Phones_v1.3.350.0.exe

launch Odin v1.7(if you get an error about some missing .dll file then you need to install the Microsoft .Net framework)

It should look like this once configured correctly:

MAKE SURE BEFORE YOU ADD YOUR FILES-THE TAB IS PLUGGED IN-YOU WILL HAVE A YELLOW COM BOX CIRCLED IN THE PIC IF IT IS CORRECTLY CONNECTED AND READY TO FLASH.

ALSO YOU MUST HAVE A BIG TRANGLE ON YOUR TAB WITH A DIGGING ANDROID (to do this power up the tab while holding down the down volume button)

Looks like this:

LOAD THE FILES AS SHOWN IN THE PIC THEY ARE CIRCLED IN RED

MAKE SURE REPARTITION IS CHECKED THE OTHER BOXES ARE CHECKED BY DEFAULT-LEAVE THEM HOW THEY ARE.

ONLY IF YOU HAVE EVERYTHING DONE. (DOUBLE CHECK)

HIT START

Do not touch anything or use your computer it takes about 5 mins to reboot your tab to the kies sync screen.

your done enjoy!

HIT ME SOME THANKS IF THIS WORKED FOR YOU.
