I have clockwork mod 3.0.2.7 and I don't believe it has EXT4 support. First, what is the difference between ext3 and ext4? Second, why are all of the latest kernels, namely Morfic's Trinity, Ext4 only? Sorry if this is the wrong place for this question. It just seems like people are very helpful here. I tried Google but I the responses were confusing. Thanks in advance.

Ext4 is faster, Trinity is true ext4, faux kernel mounts as ext4 for easy switching I guess.

Thats it. EXT4 is faster. I'm sure there are other benefits but it being faster is why you would sought after it.
I don't use it simply because I flash nightlies so often that EXT4 kernels aren't caught up. Sure they should work most of the time on new roms, but with the G2x being so new and so many changes are being made to make it stable, using a custom kernel right now just isn't worth it.
Your best bet is to focus on a custom kernel and use what they use. I would recommend cutting flashing back a little to prevent unneeded hardships with conflicting kernels/nightlies.
Once development slows down from getting the drivers to function properly, I'll give it a shot. I hear the UnderVolted kernels are fantastic for battery.
I just flash so often that it is an additional pain to flash a custom kernel over top every time. Plus I use Rom Manager which makes flashing effortlessly easy. For me to use kernels would require me to boot back into Recovery manually and flash the kernel every day.
Maybe one day CM7 will move to EXT4 and I don't have to worry about it.

I wanna run the OTB kernel from nemesis2all and it has cwm3 in the kernel is that going to conflict with anything?
Sent from my SCH-I500
The new OTB, shoudl be version 1.1b doesn't include a recovery in it, Now I did flash the one that had CWM3 in it from CWM2.5 and I didn't have any issues with it.
Now thats not to say you won't, so.
I'm running the new one without the recovery with it and its working just fine.
Alright the thing I wanted was bln, voodoo color and sound.

you need to download the respective apps from market just search for "voltage control" and "bln"... I've never used bln cuz I use noled but voltage control is really cool. Just don't choose to save as boot settings unless you are 1000% sure it's stable. The fascinate thread has a few posts with voltages to look at. My phone flakes out at anything over 1200mhz and will not even run 14-1600mhz without having to pull battery.

Mine will run 1300 no problem. Over that is gets iffy.
Mine will do 1300 but freezes when I go to reboot. Sticking with 1200

Just FYI - CWM3 would not be capable of flashing any of our flash packages as is, there is a script file located within META-INF in every flashable.zip that tells recovery how to apply the update files, since CWM3 uses edify vs. ammend scripting, our current one's are not compatible.
Phidelt has started converting the scripts (there would be 3, one for ROM flashing, Kernel flashing and Theme flashing.) However until CWM3 is used more (most people are still using the old scripts) we want to steer clear of CWM3. If you wanted that kernel (before the update which removed CWM3) you can use the SGS kernel flasher available from the market, to flash just the kernel from the .zip (it automatically picks it out)
If you do have CWM3, and want to flash something, you'll need to hop in IRC and ask around for the converted scripts - last I heard we had one complete (for ROM's) but I'm sure it wouldn't take long to get the other two converted if need be. Otherwise you'll need to revert back to the old CWM recovery.
I currently have my phone setup as ext3 running MIUI (last weeks). I want to know how to convert my filesystem to ext4 ? Do I need to run NvFlash again ?
Thanks
Not really sure how to do it manually, but if you flash faux123 4.3 kernel it will do it for you, make sure it is 4.3, very nice kernel good battery life and fast.

Well I was going to try
[ROM][Gingerbread 2.3.3] Weapon G2x 3.0_R1 [NEW TWEAKS APP & FEATURES!][10.22.2011] WhiteHawxk.
Faux .4.3 kernel doesnt convert partition to ext4, it leaves it the same, but it mounts as ext4.

Well I'm still fairly new to this and looking to learn a bit more . I am pleased with my current Hellfire 2.1 now I'm looking to exntend my battery life to the best I can and I was told this can be done with kernels, Soo I was hoping I could get some suggestions and anything that could help me out understand this a bit more.
I am currently using some Faux Kernel that came with the current Hellfire phoenix release.
Lot of people say to use Trinity with this Rom but no one says why nor in the xda page of this kernel say much about what it does, I like to be well informed before doing any changes.
also how do you install a kernel just download and install from zip from clockworkmod recovery like everything else? or is there certain steps to it?
First off this should be in the Q&A...

I'm currently testing the trinity kernel, The 1.1ghz one for the better battery. Using hellfire phoenix 2.1 so far its the rom I've enjoyed the most.
Any other kernel that anyone could recommend for the best battery performance I could get I'm pleased with the stock performance of the tegra 2 I have no need for overclocks.
Harsh kernel is the best. Flash it and see for yourself

Morfic's Trinity ELP if your phone can handle it as it varies phone by phone. But I also use Faux123's kernels and they work well enough.

When choosing a kernel you should first know that they all are, in the most basic sense the same, but have little tweaks that make them all different. I know that the Trinity kernel has the Voodoo sound driver built in that is much better than any other driver. Also when choosing a kernel you need to just try a few and see how stable they are as not all phones are created equal. Some can handle the Trinity kernel and some can't (and same with all others). When you find one that works well with you just stick with it. And, as I like to say, to each his own.
Ok all...I know about the wifi issues and all but here's my dilemma. I want ext4 on my phone but to have wifi I need to have the stock fp1 kernel which in turn makes me have rfs. Is there anyway any of you know of I could have wifi and ext4?

Go back to an EP4D based ROM, like Tweaked 1.5. Otherwise, someone will have to either modify the stock kernel or we'll need to wait until the source is released for it. Is RFS that much of a problem for you? I don't really have any performance issues with it on FP1.

I've been running rfs since FP1 came out and haven't had any issues with it. I probably would run ext4 if it were available, but I don't have any lag or any problems with rfs. They've gotten it pretty solid in recent builds.
Yeah I havent noticed any real problems with it but its just the reputation rfs has for being laggy

I believe most of that reputation is earned by misinterpreting Quandrant scores. Yes ext4 is much faster in raw read/write speeds, but raw speeds don't matter that much in the grand scheme of things unless you're streaming large amounts of data off of I/O. You will almost never being doing that on a smartphone.
Yeah I didn't notice any difference after using it for a day now

I have read here where having FP1 and a custom kernal, no WIFI. I am on the stock FP1 and showing FP1 kernal and have Tweaked 2.0. I can connect to WIFI, but when I try to use the browser for the internet, every thing is coming up unavailable. Is this what people are talking about with no WIFI or is this something new?

Check your wifi proxy settings. It should be blank.
FP1 source is out now, so we'll hopefully have a source compiled kernel in the next week or two.

Nice work here. Just what we needed. I have one request(which if you know me you know I hardly ever make them). Any way in a future release you might be able to get Badass as a governor and sio as a scheduler? I find that combo works incredibly well an another phone of mine and would love to see how it treats the 4g. Also what are you using to set UV if System Tuner ain't sticking? I really hate Set CPU so I'm hoping for another recomendation. Thanks for this.

Let me look into finding and understanding the Badass governor, as well as the schedulers. I try to be conservative and only put things in that I understand, rather than just throwing in the kitchen sink. I agree that both governors and schedulers can impact both user experience as well as battery life.
OK, I found a better source of badass from showp1984 / "Bricked"
On the UV table, I need to work through how Linux deals with what I am used to knowing as sysctl as well as what the various apps expect.

Voltage Control worked for my limited time testing this lastnight.
Is it possible to backup the kernel before flashing yours? I tried to use the SGS Kernel Flasher from the market place but it isn't compatible with TWRP. Or is it recommended/manditory that I completely reflash the OS, then flash the kernel, then just restore apps using Titanium Backup Pro? Still getting the hang of it... I just have it burnt in my memory not to restore a backup over a different kernel... thanks to bhundven

Do a nandroid prior to flashing so if something breaks you can revert.
TWRP will backup your kernel. You will also need a backup of /system/lib/modules/bcm4329.ko Using TWRP to backup /system will cover you there.
I flash more kernels every day than I want to admit. The kernel is in a different partition than the system or data, so the chance of corruption of your "ROM" is pretty small. The only file changed in /system should be the bcm4329.ko (WiFi/Bluetooth module).

flashed this kernel couple days ago, its good.
but......sad to say 4 me, i dont see any difference in battery life (running cm9, kernel it came with lasted about 16hours with wifi on and only txting), with this kernel my phones battery life only last about 8-10hours (thats with and without wifi on), trying my phone on 200/1400 and at 55% (unplugged it about 7 1/2hours ago), but my wifi has not been on. (i also saw a very bad drop rate, lost 17% battery life in about hour 1/2(wifi was off and it was just sitting)not sure if its because its set at 200/1400 or something else, and i have no other apps running in the background), im not to worried about it since im trying to buy a new phone soon, so for now im trying to make the best i can out of this phone.

Glad to hear it is solid for you!
Have you tried switching to the smartassv2 governor? It is not set as default when the kernel boots (you want a robust kernel when you have to boot into recovery).
