Following the advice from [MENTION=4410351]honeyx[/MENTION] since wayyyyyyyy back in the past, it's already been default unticked =). Also 16 bit transparency and disabled surface dithering. I think for the AROMA installer part, just ask user to do "remove SWAP" if they prefer not to have swap partition is good enough. You should focus your awesome programming skills on improving the performance/battery life instead xD! Btw, if I want to have back the responsiveness from 4.3 (before you implemented the more aggressive sleep behaviour) is there anything I can do like editing build prop? If yes, may I know what are the parameters to edit? Many thanks!
[Samsung Galaxy W I8150] hurtsky:
it lots more responsive from old kernel since i already revert into normal MEM so im not touch anymore touch responsive, about the lag after wake up it just awhile since it just to optimize more battery and it wont disturb performance.. you can rather up the frequency from 61Mhz to 245Mhz if you had problem.. but im using 61 Mhz i had no delay when wakeup the phone, just phone call is abit delay.. actually v4.3 also had aggresive sleep behaviour, but it not completely linked between each changes so it not effectively functioning, this REV version make it linked correctly and remove others useless changes

Edit: im not really expert in programming skills. i just learning it randomly ;) so im learn from previous mistake in making changes
[Samsung Galaxy W I8150] egagah:
1 last question, what is Performance Tool? What are the dynamic things that you've mentioned? But more importantly, did you enable anything that is currently on default disabled? I don't think its necessary for me to enable it if yours is disabled and you are running your device smooth and stable =P

EDIT: I will soon run out of thanks by thanking your replies hahahahaha!
[Samsung Galaxy W I8150] hurtsky:
thank you for the your thanks :D

i disable it just to ensure optimize boot timinng, i enable it using performance tools.. in my sight i disable it on boot just to easy the users to change the value of the features without making init script and it wont run twice on boot and on init it will make the boot and startup take more long time... you can read at second post and you will find out the link to the thread of performance tools for you to download..
[Samsung Galaxy W I8150] Lakum:
Thank you for introducing Performance Tool. I just discovered just now because of you. Can i use it to flash kernel on our Wonder?
[Samsung Galaxy W I8150] hurtsky:
i never use flash kernel features, so i cant give feedback on that.. you need to ask on the thread.. or maybe others user using it ;)
[Samsung Galaxy W I8150] TiTAN-O-One:
Thanks for this long note! Gonna try REV3 :)
[Samsung Galaxy W I8150] Mrkblo:
I'm sorry for asking mr hutsky, but if I want to use your kernel without the Turbo thing (I really want to be able to use my phone storage on the computer), wich version should i flash?
[Samsung Galaxy W I8150] egagah:
With swap partition you still could use phone memory from your comp. But if you still do not wanna swap you could just opt for an option "remove swap" then it'll just install hurtsky kernel without swapping
[Samsung Galaxy W I8150] Mrkblo:
According to the Turbo swap topic:

Disadvantages of a swap file on your sdcard:

A sdcard is always slower than internal memory

You may NEVER unmount the sdcard or connect your phone to your computer, because you then just kill your swap file – it is the same as pulling out the Ram of your running computer!

Maybe this is not applied for internal memory swapping? I'm really interested in using it, but I do connect my phone to the computer, preety much for charging everyday, and I always allow mtp for file sharing. If swaping the cache or internal memory wont do any harm, I think I will try it.
[Samsung Galaxy W I8150] hurtsky:
SWAP file that i put there is NORMAL SWAP, you need to read rightly.

The turbo boost mod swap is different, it is to differentiate NORMAL SWAP with TURBO BOOST swap ... see at TURBO BOOST PART, that the advantages, no disadvantage by applied the TURBO BOOST

My Review REV3

after install REV3 from REV2 and swaps 50/100/100, my HH got lag after few hours when i open browser whatsapp and xda app. I tried to remove swaps on REV3 and then got bootloop. i could not recovery with wipe cache/dalvix or reflashing REV3/REV2/4.3 again. until i restore my backup (i'm lucky :p )

then i back to REV2 but without swap and the result no more lag

my question is why i get bootloop when i remove swap on REV3 but REV2 can?

do you have more tweak or enable some tweak on your kernel, so you have different experience with me? because i didn't do anything after flashing your kernel, just it.

please advise

sorry for my bad english :D
[Samsung Galaxy W I8150] Lakum:
Hello hurtsky. Great kernel as usual. But something is happened to me and maybe only me.

I updated from rev2 (without swap) to rev3 (without swap too). It felt a bit lag. Noticeable in candy crush saga. Sometime it hangs, sometime it just return to home screen. This never happen to me at rev2 and older version. I don't know why. I reverted to rev2 (without swap) , everything is good again.

I don't swap because I tried every size and swap type combination I could but my device seems to slow. Opening application takes some time. Even system app. But I think that is not kernel related because I've been trying swap since before Rev version.

Thank you..

- XDA Rocks -
[Samsung Galaxy W I8150] hurtsky:
i don knot why it is bootloops REV3 remove many un use tweaks or anything.. it should be more lag free from previous version.. i had no lags in within 2 days usage(that my battery life for now), my CM9 is pure without any prop tweaks just Turbo Boost tweaks.. opening browser , whatsapp and wechats no problem in my case.. i think you need to prestine your phone since this new kernel slightly had many different from previous version..
[Samsung Galaxy W I8150] hurtsky:
it may related to kernel, but i do some testing like browsing and play youtube on phone, i didn't play candy crush, so i cant test it tho.. but im playing some games like Cytus, fantashooting, subway surf, temple run and TURBO , tested and run well with nice touch responsiveness.. i think it is time for you to prestine your phone, too much flashing make some system conflict.. ;)
[Samsung Galaxy W I8150] egagah:
This could be due to REV3 having removed the extra RAM mod. REV2 has 379mb or something like that. But I'm not too sure.

I had a boot loop too when I tried remove swap and go back to 4.3 from REV2 about a week ago. Also thanked god I made a backup. Perhaps the AROMA installer is not perfect at removing the swap partitions and corrupted some system files? I too have no tweaks, just pure cm9 eol + hurtsky kernels. Maybe hurtsky is right, we should go pristine. But man I'm so lazy to reset all the app settings in my phone haha
[Samsung Galaxy W I8150] hurtsky:
backup must have before flash anything, we play with system files.. there still had chances to corrupt or do some damages same file.. that normal concept.. ;)

our phone maybe in different condition.. before i had many problem, since now i just prestine my phone, all my games nicely to play.. maybe some changes had made from previous kernel, but what i confirm here REV3 use correct changes and doesn't had any hanging function just like V4.3.. in V version, Zram not correctly function because i mess up some kconfig in sources.. and many things.. so now im learning from mistake and some extra knowledge so i redo and correct back all uncorrected thing :)
[Samsung Galaxy W I8150] TiTAN-O-One:
First problem encountered :( I'm on the final OOAK Stable Build 28 but after updating the kernel to Rev3 (previously Rev2) WiFi isn't usable on Google apps like YT and GPlay Store related stuff. Whatsapp, Twitter, Facebook and XDA seems to work fine :+

EDIT: Issue is still not fixed yet. Its not the router's faulty connection but somehow the kernel or the phone since other phones can connect to it :(
[Samsung Galaxy W I8150] abhenx:
same experience :D

but when using REV2 and got lag...i could removed swap and reboot normally :p

but not lucky with REV3

now i'm using REV2 after restore old backup :D but without install swap..and good result like before.

yes maybe need pristine but same like you, it's need more time.

:p
[Samsung Galaxy W I8150] hurtsky:
youtube and google play work fine with me but this problem got happen before, the person just reflash back the original gapps and it work.... i wonder why the problem happen... i think all need go prestine before flash REV3 @_@

REV3 slightly different from previous version maybe it make the bootloop.. next version i will not include turbo boost in default..
[Samsung Galaxy W I8150] abhenx:
Understood sir :thumbup:

but your update from old version to new version was very fast...amazing update

so if need pristine every update to new version, it will be problem in time :D

but I always be patient day by day for your new updates :)

i never backup when flashing your kernel before REV, i did it when replace default arco kernel to your kernel, because i really trust on your work :thumbup::D

thanks you sir, your kernel have been making my wonder be crazy in performance, more stable than before. i

love your brain :beer:

thanks again
[Samsung Galaxy W I8150] hurtsky:
for now i only keep updating fixes from previous version... i don't think you need prestine to update each time to flash the kernel.. it will only make my user in hard state... maybe in this REV3 we need to prestine. because my phone now really in great smoothness. :D
[Samsung Galaxy W I8150] gregoriaz:
great job hurtsky, my phone more smooth for gaming use your kernel

woaaaa thanks :laugh:
[Samsung Galaxy W I8150] sinoid:
Hi all,

I would like to install rev3 from 4.3. I dont know if i have to install single swap or what. Can you help me from this point? I wont install the swap and i quit it doesn't install the kernel. So Must i install al least single swap for better performance??

Thanks to all in advance.
[Samsung Galaxy W I8150] hurtsky:
you can choose remove swap. it will install the kernel in the end.. btw, i want to release next version :) without turbo boost
[Samsung Galaxy W I8150] sinoid:
Hi hurtsky

pleasur to have an answer from you directly

IS the swap really needed?

Are you going to release a new version soon?

Thanks
[Samsung Galaxy W I8150] hurtsky:
it is depend.. not really needed, but for people feel that turbo boost boosted their performance than use it.. yea soon i will update. maybe tomorrow.
[Samsung Galaxy W I8150] egagah:
Surprisingly, removed swap with rev3 is quite lag free. And stable too =)
[Samsung Galaxy W I8150] hurtsky:
yea.. i notice it too.. but wait for REV4 ;) will more boost performance.. without turbo boost :D
[Samsung Galaxy W I8150] egagah:
Bro trust me, I check this post 3x a day haha
[Samsung Galaxy W I8150] hurtsky:
that so active ;) i already compiled REV4 for my test.. i run it with prestine because updates from REV3 with clear dalvik cache make my phone bootloops.. i think you all also will experience this later when updating for next release.. for those who not using turbo boost maybe will not experience any difficulties... next version had zram for android optimization.. use it with Zram.. i played minion rush without any lag already. ;) wait for i release it later
[Samsung Galaxy W I8150] egagah:
Ok will do. Maybe you can update the 2nd post will all the settings you're using, sort of like a starting point for everyone using this kernel. Settings like your 50/100/100 swap, how many % zram, performance control settings (like those swappiness thing which I'm not familiar with), and so on. I'd understand some settings cannot be shared as it's device dependant like UV values so just share whatever you can or willing =). Nonetheless, thanks for the continued development on this kernel. You've made this device last much longer than it should (since Samsung left us). Of course we need to thank acro and others as well for all their work combined together makes this kernel possible
[Samsung Galaxy W I8150] abhenx:
same with my experience before

with REV1 and REV2 , i got better performance after remove swaps. i want try REV3 without swaps but still afraid get bootloop.

like hurtsky said before he recommend to prestine installation to get better performance for REV3 :(

now i still with REV2 without swaps, and satisfied

:beer:
[Samsung Galaxy W I8150] hurtsky:
Update To New version :)

Edits: For those who use turbo boost maybe will end up with bootloops.. i suggest you to remove turbo boost before updating kernel just to avoid bootloops.. sorry for the trouble.
[Samsung Galaxy W I8150] hurtsky:
Just a recommended setting, you can try choose others...

Enable Zram with 18% default.. for this kernel updates... i can play minion without lag.. remove turbo boost also.
[Samsung Galaxy W I8150] mps42:
i want to know mr hurtsky if we update kernal 3 times quickly from rev 2 to 3 and now to 4 is there any problem happen in.hardware or its ok ? :) and thanks for new update
[Samsung Galaxy W I8150] hurtsky:
it wont had any problem to hardware @_@

it is same like updating other custom kernel... the bootloops happen because of clear dalvik when we changing kernel.. seem because of that turbo boost caused it..
[Samsung Galaxy W I8150] xlollomanx:
Thanks for REV4 I flash it immediately but i have a question...Do you have intention to re-implemen high-mem one day?
[Samsung Galaxy W I8150] hurtsky:
still not in my mind because i feel smoother with default RAM size in game the touch really responsive i satisfied with the performance..... but who know later ;)
[Samsung Galaxy W I8150] egagah:
Can I ask zram uses which partition to swap ram with?
[Samsung Galaxy W I8150] hurtsky:
it use RAM itself.. it most likely compress the data to make more size available RAM

read this, http://xdaforums.com/showthread.php?t=2023568

sometimes you need to search first..
[Samsung Galaxy W I8150] egagah:
Exactly the same one that I found after I asked (I should have search before asking sorry). Hmmm says there it may affect battery life. Will be observing the next few days. Btw is it me or is my lcd a little brighter in REV4 at minimum brightness ?

Edit: omg so smooth lol!
[Samsung Galaxy W I8150] hurtsky:
no need to be sorry ;) it just normal concept in XDA search first :P

yea it effect battery life abit, don't worry i just recommended the setting.. you can disable zram also, because i enable zcache in kernel it also provide more available RAM..

Owh yea, do not TICK - Allow purging of assets..i had 140mb free with disable zram.. :D

try your own setting feel which one you feel different, but i highly recommend to UNTICK- Allow purging of assets.

i recommended for enable Zram because there are some article said it boost the performance plus with enable zcache in Kernel itself.. i tried, performance kinda boosted but available free RAM because kinda not very stable.. sometimes more sometimes less.. it all just a testing.. feel free to test by yourself.. do some research also beside that ;)
[Samsung Galaxy W I8150] egagah:
This setting may eat more battery but it's so smooth I feel like I have a sgs2 lol!
[Samsung Galaxy W I8150] hurtsky:
nice to hear that ;)

next update i may try completing optimized wakeup event/ reduce wakeup event commit from Colin Cross developer... in testing period ;)
[Samsung Galaxy W I8150] egagah:
So from here i understood that what Colin Cross is trying to do is ultimately:

1) cut the time for freezing tasks

2) reduce the number of context switches and restarted syscalls

From my understanding, the above 2 things Colin has improved will in the end cause the phone to have lesser max CPU time (in other words CPU stays in high clock speed for shorter times due to faster/easier processing). So if my understanding does not fail me, if this is successfully implemented by you [MENTION=4723408]hurtsky[/MENTION], then ultimately, our phones will be snappier in terms of performance since programs take less time to thaw/freeze, while we can also save battery since CPU spends less time in high clock speeds? Correct me if I'm wrong =(
[Samsung Galaxy W I8150] hurtsky:
yup you're correct. ;)

wow you can find it the patch.. actually i already patched in our version/current version, about half of the patch itself. from the patch got 10 patch and 9 of the patch already patched in current version i left out 1 patch when i revise it back.. but in updates there are another 6 patches that he and another developer implement to optimize it more... so in test version i already included that (the version that i used now not published yet)..

and for your information.. in my CM10.1 modification with kernel 3.4.x i already implemented it 13 patches of this patch.. i left 2 because it not for our phone use and 1 patch i miss out.
[Samsung Galaxy W I8150] TiTAN-O-One:
HurtSky, i have a question for you, why didn't you implement OC up to 1.5GHz since it has the same voltage as the 1.4GHz one? It could give us more power without wasting as much battery as OCing up to 1.6 or 1.8GHz :rolleyes:
[Samsung Galaxy W I8150] Lakum:
Hurtsky, did you undervolted for your own use? If yes, how much?

- XDA Rocks -
[Samsung Galaxy W I8150] hurtsky:
try use this kernel and play games.. and you know why you no need OC with this kernel.. :)

even up 1.5Ghz and used same voltage, it same with stressing the CPU with low voltage...
[Samsung Galaxy W I8150] hurtsky:
i only undervolt -50 each frequency... :)
[Samsung Galaxy W I8150] TiTAN-O-One:
Wow, i played games like CSR Racing and i didn't notice any lag. I dare say its smoother than the Galaxy Ace 2 Stock ROM when i compare with my friends. Not only tht but the battery can last for 3hrs when i play games clocked at 1.2GHz for an hr. Really not bad HurtSky! I'll do more testing and feedback sometime later :D:thumbup:
[Samsung Galaxy W I8150] Redwraith96:
What tweak are you using ? Cause I'm in REV3 and i can't play CSR.
[Samsung Galaxy W I8150] TiTAN-O-One:
I'm using the Final Version of OOAK. No tweaks other then this kernel ;)
[Samsung Galaxy W I8150] abhenx:
FYI

REV2 without swaps to REV4, successfully. and Amazing and incredible smoothness :thumbup::beer:

thanks again
[Samsung Galaxy W I8150] sinoid:
Hi all i dont know if the following problem happened only to me as i ll describe.

Using HurtSky' Kernel REV4 i have problem with skype and videocall in order to see each other. I re-installed Version 4.3 and NO problems any more.

Is it normal: Is the rev4 manages camera fully?

Thanks in advance
[Samsung Galaxy W I8150] Ahmed.ragab:
sure the problem related to the kernel

in previous post u meant (video call on chat apps) or normal video call ?
[Samsung Galaxy W I8150] hurtsky:
i need other users confirm it.. i didn't use any video call.
[Samsung Galaxy W I8150] abhenx:
i just tried to send video via whatsapp and the result like on my picture below
[Samsung Galaxy W I8150] hurtsky:
no he said video call, whatsapp didn't have video call.. i don think video call is work in CM9.. i got used tango.. but now i didn't anymore..
[Samsung Galaxy W I8150] abhenx:
yes I know, but when he said could not use video call on social media like skype. i tried to send video capture via whatsapp..and the result like my picture. look like taking video could not working on whatsapp, or only me?

plz advise
[Samsung Galaxy W I8150] hurtsky:
just tested on pure CM9, whatsapp can send and take video flawlessly..
[Samsung Galaxy W I8150] abhenx:
sorry my fault sir :p

i have been freezing galery app, and replace with xperia album.but after defrost it, taking video via whatsapp working normally

i'm sorry again :D
[Samsung Galaxy W I8150] sinoid:
HI all i meant video call over WIFI with rev4 has problems. No problem with 4.3

Concerning Videocall over UMTS i understood that there is NO WAY to make it on all CM,
[Samsung Galaxy W I8150] hurtsky:
just now i find my little bro to do video call through wechat, working flawless also.. nothing wrong or error... can video call nicely..
[Samsung Galaxy W I8150] Dwama:
i have a problem with recording the video and it keep stuck every second , when im done recording, it took along time to stop the vid. and when im trying to play the camera using default and mx player, it only cane be play until 0:02 , then it stucked until the end of the vid .

anyone experienced same problems as me ? :(
[Samsung Galaxy W I8150] TiTAN-O-One:
Actually, yes. I can't remember what i did but it all went well after that :rolleyes:
[Samsung Galaxy W I8150] egagah:
So what's going on with this kernel now hurtsky haha. This thread is so quiet that I felt something is amiss. Perhaps a little sneak peak to the future features added in rev 5? Sorry for my impatience
[Samsung Galaxy W I8150] TiTAN-O-One:
Yeap! This thread is so suddenly inactive! Maybe you are doing smthin' BiG for us? ;)
[Samsung Galaxy W I8150] hurtsky:
i at university now ;) just reach here for new semester.. but don worry.. there sure will be have few updates :D i had done few updates on my repo
[Samsung Galaxy W I8150] fivezall:
hi to hurtsky.. your kervel REV version is awesome but i want comment one thing.. its about sound.. before REV Kernel, sound it to good for me and i very like but when you launching REV kernel, the sound not to good. Can you make REV kernel version have good sound like before? tq :p
[Samsung Galaxy W I8150] hurtsky:
about the sound it same adjustment like previous version, i only include loudness tweak i do nothing more...

Now testing zram from 3.7 for our 3.0.x kernel ;) kinda feel nice now
[Samsung Galaxy W I8150] hurtsky:
Update To New version :)

Huge Updates

- Please Activate KSM and Zram at Setting > Performance for better performance !
[Samsung Galaxy W I8150] xlollomanx:
Which ratio of Zram compression do you think is better? 18% or what?

P.S= thanks for your new version :)
[Samsung Galaxy W I8150] hurtsky:
default 18% should be fine.. just try any value..
[Samsung Galaxy W I8150] egagah:
First and foremost, A HUGE THANK YOU FOR YOUR HARD WORK!

I think post 2 needs some cleaning up (old features can be tagged out). So I'll remove uksm default on then haha. One question, all the tests mentioned in the changelog means we will be testing them is it?
[Samsung Galaxy W I8150] hurtsky:
it in test because the performance improve slightly but not dramatically.. i did some test but only abit improvement.. about the compaction.. not really know how good the compaction of memory it will be.. that why i put test there ;)

about the cleanup. i will do later.. doing work with laptop not really my type..
[Samsung Galaxy W I8150] egagah:
flashed and testing =P! man changes in bfq and deadline as well as a new sioplus! dunno which is best now >_<! currently giving sioplus a run. How about yourself?
[Samsung Galaxy W I8150] hurtsky:
i used SIO plus for now...

here some explaination of SIOplus

Block: Add SIOPlus

The Simple I/O scheduler is an extremely simple scheduler, based on noop and deadline, that relies on deadlines to ensure fairness. The algorithm does not do any sorting but basic merging, trying to keep a minimum overhead. It is aimed mainly for aleatory access devices (eg: flash devices).
[Samsung Galaxy W I8150] yugioh93:
Can i ask about the REV5 installation method?
[Samsung Galaxy W I8150] reinjoy:
back read

-all instructions are given in the 1st page bro..

-go read for yourself and you'll be astonished..lol

-salute!
[Samsung Galaxy W I8150] slovee78:
dear hurtsky,

when I flashed the REV5 the total memory is still 352MB not 378MB. Is REV5 uses low memory or is there something wrong?

Sorry, It's OK. I read the changelog. It's normal mem not high mem.

have a nice day.
[Samsung Galaxy W I8150] kabychow:
