@hardcore, how about implementing ext4 lagfix into your kernel? When are you gonna do that? I'm waiting only for this one feature :]

I (and a lot of people) love so much your job and support you

please please all : let that topic readable and please stop "i missed you" i love your job" ... if you want to thank HC just clic the "thank" bottom cause it is very hard to find real information about bugs and cheats on that topic

thanks by advance

EDIT : hardcore, please let me know if all improvements about GPS, wifi, battery ... included into K13x was included too into K15A ?

JVP + H15H-T8 + GTalk 1.3 + VoIP = <3

I'm using Ramad's JVP with K15H-T8 and everything is really cool here: no reboots, nice battery, front face camera working.

I have installed the GTalk 1.3 for GB 2.3.4 and was able to perform video chat over WiFi with no problem with a desktop client. I have not tested it with 3G.

I have also applied the framework update for adding VoIP native support and it's running fine over wifi and 3G.

For me, hardcore can freeze K15H on T8 (NOT T8B!) and release it as stable :-P

I personally prefer the kernel with cpu deep idle disabled.. Correct me if I'm wrong but ifu keep getting a lot of messages or calls (like in my case) its better that deep idle is disabled.. I feel it gives me better battery life.. Even t5 which had it disabled worked very good for me..

In the startpost:

This kernel has only EXT4 LAGFIX support. Please UNDO OTHER LAGFIXES before flashing this kernel.
[Galaxy S I9000 Android Development] ukdtweak:
Yes, a few of us that used Ramads Deodexed rom have this problem, check the Stock 2.3.4 thread, there is a CWM.zip to flash a working phone.apk, though I have flashed it, not had any more calls to verify if it fixed the issue...

I Flashed Stock JVP via ODIN from Romads collection, then flashed SM K15 T6 and then flashed Romads deodexed JVP and again flashed SM K15 T6.

Only time I had a problem was after I enabled EXT4... after a few hours my phone locked up and I had to Hold PWR button untill phone rebooted, since then I disabled EXT4 and returned to RFS and the system has been Stable, fast and great battery... so I am sticking with it for now.
[Galaxy S I9000 Android Development] russell.nash:
Just flash speedmod over your existing setup. It will work. I did the same thing.
[Galaxy S I9000 Android Development] Ticiano:
Voodoo sound

I know we have a lot of kernel options around, but I just learned to trust hardcore's. ;) As I was used to like the Froyo versions with all that options, it would be awesome to have voodoo sound in gingerbread kernels.
[Galaxy S I9000 Android Development] demonstone:
but you could have voodoo sound without a kernel that includes it, simply buying supercurio's app voodoo control plus, and so you'll be supporting supercurio's work, isn't it?

it is only 2€, and you'll have voodoo sound to the end of times...
[Galaxy S I9000 Android Development] hippo_potamus:
I'd prefer K15H-T8, no issues since flashed when it came out.
[Galaxy S I9000 Android Development] P$T:
@hardcore

Sorry about this..but why you don't include voodoo sound, but you steal some supercurio work ?
[Galaxy S I9000 Android Development] HM.Carbide:
Steal from open source? And hardcore always released his source too!

I think hardcore made a good solution.

There is some basic support for better sound quality, and if you want, you can use Voodoo Control Plus, and have always the latest version.
[Galaxy S I9000 Android Development] washburn111:
It works on mine.
[Galaxy S I9000 Android Development] lpy:
Which ROM are you using?

Im guessing auto-brightness doesn't work on JVP but is still ok on JVO? I could be wrong though.

It's weird, some people say it still works fine, but for me it works fine on a stock kernel, but not on any version of Speedmod. JVP.
[Galaxy S I9000 Android Development] daigoro64:
The issue is present on all re-compiled JVP kernels, due to outdated (yes, Sammy did it again) sources.
[Galaxy S I9000 Android Development] lpy:

With the "Mount Manager" app there's no need to have a working init.d scripting.

I did this:

1) copy the slow-work.ko & cifs.ko to the internal sdcard. I copied with root explorer in /system/modules but I thinks it dosn't matter where

2) In the app you can configure the modules to load. Look at the 1st screenshot. Make sure, to load slow-work.ko first. In the app you can set the priority

3) In the preferences you can no let the modules load automatically (2nd Screenshot)

[Galaxy S I9000 Android Development] jaiiscool:
I found that the phone is running smoother with rfs, is there something wrong with ext4 implementation or rfs just got soooooo much better.
[Galaxy S I9000 Android Development] davidf:
RFS got better along with a few other things, with JVO/JVP standard rom and a decent kernel you just get smoothness and speed, every custom rom out there is currently causing micro lags. time to kiss de-odexed roms and placebo lagfixes goodbye, now its just about getting a decent kernel and hardcore is doing pretty well in that area.
[Galaxy S I9000 Android Development] EarlZ:
Good thing I dont have those micro-lags on my phone!
[Galaxy S I9000 Android Development] LordVetinari:

Microlags??

Hi Guys is this right that only on Stock ROMs with a good Kernel microlags are gone?

Because i treid so many ROM's and i always get sometimes microlags. Sometimes it hangs when i scroll in Contacts. And i hade something like this :-(

But i i flash a Stock ROM + Speedmod Kernel can i use Jkays Theme?
[Galaxy S I9000 Android Development] Bangdoo:
Or is also good to use a doedexed ROM from RAMAD.

i was on stock and speedmod only and got that when switch to T8. lets see if i have the same problem tomorrow morning and the clock don't go off. :)

but i also got the battery leaks issue. i only know the battery drain is caused by some wireless process not turned off correctly as my phone gets hot. previous way to fix it is reset. now monitoring the issue with watchdog task manager see if it helps.

[Galaxy S I9000 Android Development] Bangdoo:
Are you using a Theme?
[Galaxy S I9000 Android Development] Giginicchio:
No I don't use any theme, why?
[Galaxy S I9000 Android Development] bitblaster:
Just to confirm that I'm using Darky's ROM 10.1 RE (ext4 lagfix), and since I put the T8 speedmod kernel, my phone is unbelievably fast!

And when I say unbelievably I'm not joking, it's 2-3 times faster in every aspect (I have a 150+ apps, many services, including tasker, k9,

go launcher, etc), boot time of 28 sec, and instantly start of all apps (i.e. opera Mobile 3secs)!!!

Not only: previously I had only 45-50 MB of free ram, now over 150, so I think the Darky's kernel has some strange bug, expecially regarding ram usage.

In any case gingerbread on ext4, even using the darky's kernel, is way faster than froyo on ext4 + speedmod kernel, in my opinion.
[Galaxy S I9000 Android Development] yalouf:
Can somebody tell me if there is more battery life without lagfix or not ???

I think gb should be fast enough without lagfix by now. But I have speed mod lagfix atm. If you tell me I may have better battery life I may revert back :)
[Galaxy S I9000 Android Development] jaiiscool:
I just converted back to rfs yesterday and I already see an improvement in battery life.
[Galaxy S I9000 Android Development] demonstone:
Why do you all are still naming ext4 as lagfix when there is no lag to fix on ginger? Why don't you call it "system file conversion" or simply sfc? Looool

I am currently using it with speedmod, and have used it with several different kernels in the past. As I mentioned earlier, it loads a module to overclock.

[Galaxy S I9000 Android Development] mab71:
quardrant scores are not 100% reliable... its the UI experience that determines the performance.... i personally feel there is no reason to apply lagfix(ext4) with 2.3.4 as the rfs + speedmod is superb enough....mine is running almost like iphone4
[Galaxy S I9000 Android Development] biohazard.tan:
Unfortunately for me, it's the opp. After running RFS for a day and enabling lagfix, I find lagfix so much smoother. :)
[Galaxy S I9000 Android Development] elhennig:
You should wait some time in order to take fs fragmentation into account. As far as I know, RFS is based on FAT plus some transactional extras. But it is still FAT. Hence, the filesystem will fragment...

BTW, has anyone tried to use btrfs?

Sent from a galaxy
[Galaxy S I9000 Android Development] hardcore:
That's why there is now a 'unfragment' feature - just convert rfs to rfs and you unfragment it.
[Galaxy S I9000 Android Development] jaiiscool:
where is that option? CWM?
[Galaxy S I9000 Android Development] mab71:
Just go to rec>speedmod options>convert fs to rfs....you have to be on rfs first though
[Galaxy S I9000 Android Development] elhennig:
And still one more unnecessary thing to keep the filesystem in a proper state. Unnecessary, because other filesystems do this internally and automagically.

P.S: What about btrfs? Have you tried to compile the kernel with btrfs support?
[Galaxy S I9000 Android Development] DocMarc73:
AFAIK btrfs is not completely stable (no fsck tool support) , so i don't think hc will take it into account.

Hardcore has to speak for himself but, from what see here, his main focus seems to be aimed at stability and i guess he won't implement anything that's not proven stable so far ...

Personally i think btrfs looks very promising ... !-)
