"It was a great honor using ur Kernel sir, my GNEX is very proud of that."

I am excited to know the name of the new kernel, is it going to be DirtyV or can we expect some rebranding...

DirtyV +

DirtyV2---which dirtyV square, denoting the improved graphics driver and lollipop support, etc

I know i am being over excited here, just couldn't resist:good::good:
[Samsung Galaxy Nexus] Nephilim:
If you get it running with working mobile data I would be glad to test the rom and your new kernel betas.

Just flashed the DirtyV-final and it's flying. Awesome job! Worthy of the final tag for sure.

Found a new option on trickstermod, it's IVA OC, what does it exactly do?

However this version is really fast and the smoothest i've ever seen, temp lag seems vanished. Thank you sir for all the effort put on this kernel.

Sh*ttyV could be a good start ahaha I'm obviously joking.

I've experienced just a temp lag this morning during typing with keyboard on clash of clans, nothing more. However i'm really satisfied; on pre-final version temp lags were almost a routine. I hope that the new gpu drivers will help in this way.

[Samsung Galaxy Nexus] sagara.sandaru:
Is this happening because of the touch boost thingy?
[Samsung Galaxy Nexus] osm0sis:
No idea. I know it doesn't happen on 8.30.14 and I keep going back to that build to get away from it. 11.9.14 is a rebase from 8.30 but still seems to contain the problem, whatever it is. :eek::(

http://v.ht/osmods if anyone wants it from my BasketBuild to compare. Latest ramdisk of course.
[Samsung Galaxy Nexus] pattyboi:):
to anyone wondering:

IVA oc is a toggle for overclocking the image/video acceleration chip,which also sometime can help with dsp (audio processing) lagging in heavy apps,im pretty sure when i did the pull request for smitty i set the oc freq to 430 mhz,all tho he couldve up'ed it

Guys I have been getting this issue since a long time the problem is that when I overclock gpu to 512 I get graphical glitch whole scrolling extremely annoying also I am getting random reboots on the latest dirtyV SR other than that it's rock solid
[Samsung Galaxy Nexus] Culex316:
Thank you very much for all your effort in making yet another great custom kernel alternative for our Galaxy Nexus!

I don't post much, but I do follow this thread and your work has been nothing short of phenomenal.

I am looking forward to the Lollipop kernel and I hope that this old 3.0.x kernel base doesn't pose too much of a problem when adjusting it for this new Android version.
[Samsung Galaxy Nexus] osm0sis:
Franco is the only one I know of who made 512 work for everyone by locking certain core voltages in and not using variable oc. Worth checking out if you really want 512. I just uploaded a Synapsed version of r398 the other day. :good:
[Samsung Galaxy Nexus] CoDe LaZaRuS:
Overclocking on fancy works fine and so does the stock kernel. Only seem to be having this problem on dirtvV ?

What exactly is synapsed version of r398 a little detail is appreciated.
[Samsung Galaxy Nexus] osm0sis:
You could probably bump up the core voltages on DirtyV and have 512 work fine for you too. r398 Synapsed osmod is obviously franco.Kernel so you can check that thread for my explanation if you're interested. :good:

[MENTION=4608636]bsmitty83[/MENTION]..

I am currently on fml lollipop version...

Do you think zImage from your current build (final one) would work with it?

I would really love to try this rom out with your kernel...

Even though it is with older gpu libs... I have a feeling that there will be much better performance and battery life with your kernel...
[Samsung Galaxy Nexus] seriousia:
No

Ok i'm quoting my self again

According to this patch it introduces FITRIM in f2fs_ioctl.

So just want to ask if it is already included?

Sorry for posting again :D
[Samsung Galaxy Nexus] bsmitty83:
no i dont recall seeing that , although i did add fdtrim to ext4 , i could be wrong due to the amount of f2fs commits but i'm pretty sure its not in there

Downloaded & installed DirtyV-SR plus buscher's (sp) init.d script per instructions (which aren't clear whether both scripts are necessary or just the preferred due to saying 'scripts' on instruction line 1 but 'script' on line 2), renamed, copied, set permission and rebooted my toro running the latest AOKP nightly.

Toro immediately suggests the battery, which was around 80%, is almost empty. Settings appear applied in TricksterMOD, but should I be worried? Battery shot up to 49C so I switched the governor to powersave...
[Samsung Galaxy Nexus] ahmadairfan:
This kernwl was not that good on my gnex. Heat problem, lags (just a minor lag though), huge battery drain, and charging takes much time. I don't know why. Maybe core/IVA voltages not playing nice with my device?

Few pages back, there's a suggestion from [MENTION=4544860]osm0sis[/MENTION] to bump the core voltages up. My idea is to change the core voltages to be the same as other kernel (mention it Fancy). But then I just realized that DirtyV has only 3 core voltages, not 4 like in Fancy? :?

Some basic knowledge will be very appreciated, thank you :)
[Samsung Galaxy Nexus] geodescent:
I ended up deleting the initd script, rebooting to cwm and hopping over to fancy. Worth noting though that as-is, dirtyV ran way snappier than cm-11 even under performance.

Sorry if a dumb question, but how should I go about achieving the dvrevertmedia script to get back 1080p recording and essentially truly undo dirtyV installation? I've attempted the script in Rom Toolbox thus far. I will have to check permissions in the directories the script references.
[Samsung Galaxy Nexus] DR3W5K1:
Just reflash whatever rom your on no wipe needed. Flash kernel go to go
[Samsung Galaxy Nexus] osm0sis:
[MENTION=4608636]bsmitty83[/MENTION] still planning on building TWRP 2.8.1.0 with f2fs support? It's a gap nobody else has filled yet. :)
[Samsung Galaxy Nexus] amd_h4x0r:
Another slight off topic:

I was going to try the new Lollipop build here but I had to change back to ext4 from f2fs. I somehow managed to format /data and now my entire phone is wiped.

Is there any way to recover the data that might still be on the sdcard? I haven't tried sideloading anything yet because I don't want to overwrite anything that might be salvageable.

Maybe there's a way to do an adb dump of the entire phone and then recover the files that way? I'd rather not have to go back to an old nandroid saved on my computer from over a month ago.

EDIT: I'm trying this method right now. Will report back once the entire phone has finished copying.

EDIT2: After spending quite a few hours getting a raw internal dump, I still wasn't able to pull any un-corrupted files from it. I'll be sure to copy my TitaniumBackup and TWRP files on a more regular basis now.
[Samsung Galaxy Nexus] bsmitty83:
I believe Boype added a few more Core OPPs , thats why there are 4 .

the revert script should run anytime a non-DirtyV-SR boot.img is flashed . so if you dirty flashed fancy anykernel over my kernel then that could be the issue . dirty flash cm and then fancy and your cam should be fine

I guess ........:p

although everyone seems to complain that its not "official" , I'll still build it since I do anyways for myself
[Samsung Galaxy Nexus] szale9001:
Hell, I couldn't care less if its official... it works lol.

Also, assuming its not terribly difficult, would you mind including this so us weirdos who encrypt can get lollipop support :p

I have a question that is not specifically dirty V kernel related but a general minfree question.

If I increase the RAM on my Gnex from normal asram (742-749MB) to super RAM (772-785MB) by ****ing around with the omap tiler memory allocation in the source code and then recompiling and flashing , should I adjust my min free values accordingly or would this small RAM increase not warrant a change?

I figure with more free RAM I could afford to lower the values a bit to have better multitasking and not have all the apps redraw everyone I switch to them.

With dynamic fsync there is no need to completely turn fsnyc off. As metalspring mentioned when dynamic fsync is on then fsync is only off when the screen is on, which is the only time you really would need the improvements having fync off provides. Turning dynamic fsync off turns on fsync completely for those worried about data corruption. (Which is possible but I myself have never encountered)
