[Sony Xperia S, Acro S, Ion] Galaxen:
Ive been using XTX7 with Arkmaar Adv Stock Kernel 17 for a while now but Im getting lots of memory issues. Reboots, freezeups for 5-10 sec s and complete freezes etc, memory runs out all the time every day more or less(20-40mb) :confused: I cant reboot every day. Ive used Autokiller memory optimizer pro but it doesnt help at all. So my Q? Is memory management mostly dependent on Kernel or ROM?

Since Ive had this issue on most ROMs Ive used and always had Adv Stock Kernel so i wonder if its me or the kernel? (cant be ROM) Will this/your V3 kernel be any different? or is it my daily use that puts too much pressure? Any help will be appreciated.
[Sony Xperia S, Acro S, Ion] tosa.th:
I'm not an expert nor a developer. I'm just a moder at best.

I use to have freeze problem once I play with dalvik tweak for deodex ROM and/or new GPU driver from XTX7 thread. I do not know for sure which one cause me freeze issue. I end up with restore the my nandroid backup.

I personally try a lot of kernel and Arakmar's kernel is the best for stability. It is very close to stock kernel. I think your problem should relate to rom or some application that you install afterward. I think Stock+ V3 will not give you any different.

When you install new rom, did you do a clean install? Personally before install a new rom I always factory reset (this will format cache and user data) then I manually format system. Then I install a new rom.

If possible try to use rom without any mod first to see if the freeze issue is disappear. The other thing is application, try to install them from market or truthable apk file not from titanium backup, I heard some time restore from backup cause some issue.

Task killer is not need it doesn't help. I take it from faux123 the recognize developer.

"Please DO NOT use any task killers, they DO NOT improve performance nor battery life. They INTERFERE with your phone's stability (more crashes) and App compatibilities (Forced Close)."
[Sony Xperia S, Acro S, Ion] Stenlius:
After using you kernel for a while I think it's on par with advanced stock kernel - both battery life and performance. It is stable - i've experienced no bugs at all. Maybe you could work for some additional performance without overclock and losing stability, it will be a very good alternative to advanced stock kernel out there. And please make a fastboot version :).
[Sony Xperia S, Acro S, Ion] tosa.th:
Thank you for feedback.

Regarding to advanve stock kernel, I took ramdisk and mmc fix from his kernel merge it to .55 stock kernel source. You could see from OP post it is very close to his kernel. Anyways there are some different which I mod to suit my preference e.g. superSU, minimum clock speed at 192Mhz, ondemand parameter tweak for battery life and lately PegasusQ governor this also for better battery life.

Do you use PegasusQ?

Regarding to fast boot version just extract kernel.elf from the zip file.
[Sony Xperia S, Acro S, Ion] Redstarr1:
A quick report. I have my phone running for 33 hours on your kernel without recharging, rebooting or any apps FCing. Was at about 21% battery but now I'm recharging anyway. Most of the time I used PegasusQ as governor and no other changes to I/O scheduler or clock speeds.

As far as stability or battery performance goes, the kernel is really good. I have 160MB of free memory which is about exactly the same as 24 hours ago, so no memory leaks or stuff like that and in my opinion that's plenty of memory backup in case I open a memory hungry app.. Your tweaks probably saved some battery life but I would have liked a little more performance, everything is a bit more sluggish compared to Arakmar's kernel. I noticed it most in the launcher (widgets get loaded late really often) and when opening apps. So the battery part you've got covered, now for a bit fluidity? :p

EDIT: I just noticed that I changed the I/O scheduler to noop. Changing it back to deadline made the launcher a lot more fluent :).

EDIT 2: The combination PegasusQ and deadline scheduler seems to make the phone very unstable.. At first wifi wouldn't work anymore. Clearing cache and dalvik cache fixed that, but now when I enable my cpu settings (PegasusQ+deadline+default clock speeds) the phone gets hot in the left top corner and reboots most of the time. My cpu control program sets the settings back to default in case of an unexpected reboot, so the phone works fine after rebooting. Changing the scheduler back to deadline will make the phone reboot in a few minutes...
[Sony Xperia S, Acro S, Ion] Stenlius:
I only used tweaked ondemand, as for the fastboot - thanks, shoul have figured that :). Will give it another try with PegasusQ.
[Sony Xperia S, Acro S, Ion] tupacsoul:
Bricked after flashing..... good. :(
[Sony Xperia S, Acro S, Ion] tosa.th:
Thanks, may I know what ROM you are using? what is your CPU control ? Any additional tweak?

I use with a slightly modified stock ROM without any tweak and setcpu I never experienced reboot or lag with pagasusq+deadline

If you still not giveup on this kernel and want to test some more IO schedule. I have some more i.e. SIO, ZEN and ROW io scheduled.
[Sony Xperia S, Acro S, Ion] tosa.th:
What you did exactly? Can it recover?

It is too little info you gave here.
[Sony Xperia S, Acro S, Ion] tupacsoul:
After 4 hours I could recover from flash tool and .45 stock. The problem was a Bad flashing with the kernel. Now everything works ok.

Thanks.

[Sony Xperia S, Acro S, Ion] Redstarr1:
Sorry for the late answer, I didn't have a lot of time because of new year's and studying. The ROM I'm using is XTXperience v7, I use No-Frills cpu control as CPU control app. Didn't change anything aside from governor and scheduler. PegasusQ + deadline does work but only if I set it manually after rebooting. If I reboot while PegasusQ+deadline is active, the phone becomes unstable the next boot and resets.. Have been experimenting with some other kernels the last few days because just ondemand+deadline wasn't very spectacular, but if you have a good one ready, I'll try it :).
[Sony Xperia S, Acro S, Ion] tosa.th:
As your comment about No-frills, I just try it on mine and it cause me a lot of problem. Sometime it just stuck at highest speed. After screen off It cause my phone to reboot. I'm now suspect No-frills. Is it possible for you to try setCPU. I never have problem with it.

I will update the OP for V4 link. Not much update mainly add I/O scheduled.
[Sony Xperia S, Acro S, Ion] Redstarr1:
I can't use setCPU because that's a paid app and I don't have a credit card. It's not that I'm stingy, €1,5 isn't that much, but you need to have an income in my country to have a CC and I'm still a student for 6 more months.. I could switch to AnTuTu CPU Master, does that give issues for you? On Elite kernel with badass or intellidemand governor I don't have issues with no-frills, maybe it's the specific combination PegasusQ+Deadline+no-frills...

I'll report how V4 works with AnTuTu then.
[Sony Xperia S, Acro S, Ion] SimonZ:
Is possible to add voltage control?
[Sony Xperia S, Acro S, Ion] tosa.th:
Antutu working on mine.
[Sony Xperia S, Acro S, Ion] tosa.th:
I think it is possible but there are two kernel for stock base rom that have voltage control out there.
[Sony Xperia S, Acro S, Ion] SimonZ:
Where? i foun another one kernel by Arakmar but incredicontrol not work with this stock.. Anyway thanks for your kernel!
[Sony Xperia S, Acro S, Ion] Redstarr1:
SSpeed kernel and Elite kernel both have voltage control as far as I know and are stock-based. Arakmar's kernels are even more stock than this one, no special schedulers or governors there.
[Sony Xperia S, Acro S, Ion] SimonZ:
SSpeed and elite have both GPU overclock and i'm extremely conservative so i'm in doubt if install.

I prefer real stock with little optimization and possibility of undervolt.
[Sony Xperia S, Acro S, Ion] Redstarr1:
Ah you wanted to undervolt. I thought you wanted to raise the voltage. There's a version of Elite without GPU overclock though, it's very much stock based as well.

Update

Update

- Add Badass governor

- Unlock Interactive governor

- TWRP recovery
[Sony Xperia S, Acro S, Ion] Redstarr1:
I've been using V4 for about a week now, everything's going well. Can't really say how the battery life is because I'm at home studying most of the time, so I just charge my phone frequently, but I think it's still about the same as before. I like the new governors and schedulers you added. After some experimenting this is what I settled with:

- Max frequency: 1512 MHz

- Min frequency: 384 MHz

- Governor: Intellidemand

- Scheduler: row

Other schedulers I played around with were zen (but I don't really know what that does, can't find a lot of info, not very different from deadline anyway) and also cfq which was a little better compared to deadline but the overall experience felt smoothest with row.

I also upgraded XTXperience 7 to XTXperience 8(.1), which is very smooth with the above settings. One issue I have though is that PimpMyRom is built into that rom and it doesn't seem to apply frequencies, governors and schedulers when rebooting, it always resets to default. When I use Antutu CPU Master instead the settings are set at boot, so I'm assuming it's a problem with PMR.

I might try V5 now, but I'm a bit wary of TWRP.
[Sony Xperia S, Acro S, Ion] tosa.th:
Thank you for feed back. You don't have to try V5 coz V5.1 is out.:p

[Sony Xperia S, Acro S, Ion] Crocodile1973:
Anyone know of an app that can reboot into TWRP from android OS
[Sony Xperia S, Acro S, Ion] tosa.th:
I read it from somewhere cwm backup not compatible with twrp. You will need to create a new backup.

I used to use quick boot with my htc but it not appear to work with XS. Now I don't use any app because TapNGrid systemUI mod for XS allows user to boot to recovery. Well, it state "CWM recovery" but with this kernel it will boot to twrp.

[Sony Xperia S, Acro S, Ion] 3vilhomer:
so i should use a flash tool and flash in this TWRP and i should b fine right?? or i have to flash to the .55 firmware first??
[Sony Xperia S, Acro S, Ion] Redstarr1:
You can use flashtool to put your phone in bootloader, yes. But first you need to unlock the bootloader, or you won't be able to flash a kernel. Be aware that unlocking the bootloader has consequences such as downloading music info in Walkman not working anymore and the Bravia Engine also not functioning anymore. Your phone will also be wiped if you unlock the BL and you won't be able to update through PC Companion anymore. But most of the time there's a newer version available than the one offered through PC Companion (2.55 is only official in a few Asian countries).

You can find out how to do this in this thread: http://xdaforums.com/showthread.php?t=1526866 There are links there that show you how to do most of what you need to know. The information is a bit outdated, so don't mind what he says about specific kernels and recoveries, but the code is still the same (fastboot flash kernel kernel.img is what it comes down to :p). Doomlord says to use fastboot, which is what I also use, but you can also put Flashtool in fastboot mode without having to install the Android SDK (press the lightning bolt and select fastboot mode). The kernel you need to flash is located inside the zip you download from this website. When you have a custom kernel, from then on you can flash zips with the recovery, but for fastboot it needs to be an img, elf or sin file.

However, if you were not planning on ever installing a custom rom, I wouldn't bother unlocking the bootloader just to install a custom kernel. It is an improvement for performance but the major reason is easily installing any custom rom.
[Sony Xperia S, Acro S, Ion] mrsatan:
You need to unlock the phone first, that msg means that you are allowed to unlock it.
[Sony Xperia S, Acro S, Ion] davidbar93:
How is the overall perfomance with this kernel? Comapring to custom kernels like SSpeed.
[Sony Xperia S, Acro S, Ion] tosa.th:
It may not fair to compare NONE O/C kernel to the O/C kernel :p

This kernel is not for O/C it is close to stock but with little extra thing like more govenor, I/O schedule and different recovery.

No Wipe cache bug!!

Can you make this kernel supports my xperiaSL?I am gotta be crazy at that 1674Mhz speed :D
[Sony Xperia S, Acro S, Ion] tosa.th:
Sory for a bit late response. I was looking around how to make it work for you.

I use sony stock CPU frequency and in the code it has frequency table upto 1674Mhz.

I believe the kernel should read cpu frequency and set the right one for you.

I don't have SL so can not test it. However I found some interesting thread

http://xdaforums.com/showthread.php?t=2108464

"The Xperia s kernels should work on the sl, the only difference is the sl has a faster dual core and different colour options, try it if it dose not work then flash back to stock"

Another thread http://xdaforums.com/showthread.php?t=2094438

Looking at his screen shot you could see he use Arakmar kernel (This is advance stock kernel) as far as I'm aware there is no special version made for SL. I did send him a PM to ask him to confirm what I saw and to check the CPU speed he is using but so far there is no answer.

Well, If it is not work I will try to make another one for you. But it is unlikely to happen:fingers-crossed:, I also check the def_config of the S and SL, only one line is different.

Re: [XS][Kernel][STOCK+] V5.1 Update TWRP recovery 2.3.3.0

Freaking awesome!

Tosa... Could you make an oc version of your kernel... If you are free to do so... Hugely appreciate.
[Sony Xperia S, Acro S, Ion] tosa.th:
OC to XSL speed

After looking around for the XSL. I found the CPU frequency table for the XS define frequency upto 1674Mhz but XS use only 1512Mhz. I guess it is for the XSL. So I just change the max frequency of the XS to 1674Mhz same as XSL!!

Ues it for a day without a reboot.

Some people do not want to use O/C kernel so I made a change in ramdisk to limit max frequency at 1512Mhz same as stock speed. This limit can be changed later after boot by using app like setCPU or Antutu.

Re: [XS][Kernel][STOCK+] V5.1 Update TWRP recovery 2.3.3.0

Great kernel, love recovery, problem it takes to much space on a backup. Cwm can get them down to 30mb ish.
[Sony Xperia S, Acro S, Ion] Redstarr1:
How is it even possible that your backups are only 30MB... If you do a full backup you take the complete contents of your /system and /data partitions (and some other stuff). Even when you compress it, you'll never get that down to 30MB, so you're probably just looking at the wrong files of your CWM backups. There's not much difference between TWRP and CWM for me in backup size.
[Sony Xperia S, Acro S, Ion] tosa.th:
Please take look at blobs it is a huge folder isn't it. If you check the whole clockworkmod folder you will see a lot bigger than that. I have 7 backup of CWM and it took 2.3GB so it is about 300MB each. It is smaller than TWRP but not down to 30MB:D

I agree back up space is not the advancetage of TWRP but for me I like that it has feature to name a backup so you know what it is, when it was. CWM name it backup by date and time but it is wrong date. 1970 don't remind me when I want to restore a backup :D

At the end of the day it down to user preference.

Thank for the feedback.

problem with set at boot.

Not sure if anyone has problem like me. I just found that setcpu and Antutu set at boot function is not work correctly. It is appear that the first core is correct but not the second core it is still using ondemand the default. There is another similar app call No-Frills and Kernel tuner which do set both core correctly but unfortunately it doesn't like Pegasusq.

Quick note. Badass and intellidemand work with No-Frills and kernel tuner. I do not yet try with any other governor yet.

Please also note that the max speed of second core will also not stick at setting value. This is not only this kernel but should be all kernel even on htc device.

Re: [XS][Kernel][STOCK+] V5.2 Enable to Over Clock to match XSL speed

Wanted to share my thoughts regarding 2nd core :

1.In stock versions both work. 2nd is triggered only if required.

2.In OC versions :

a. only one works.

b. To trigger the second, we need any kernel tuner.

c. 1st can be uc/oc... 2nd can also be done TILL THE KERNEL TUNER APP IS RUNNING.

d. On exiting the app that 2nd core sets to the max oc level.

Conclusion : good job dev. But users need to be careful using oc version. It's with all kernels.

Could you make an OC and non OC version?

And another thing,if I install this on a new,fresh,and clean install ROM,SuperSU won't work.

A solution is to install another kernel (Advanced stock for example) run Superuser,run SuperSU and revert to this kernel again.

I know you mentioned the auto root function is broken in OP. It would be nice to fix it :)

I really like the TWRP :good:

Yes this kernel supports the extract_elf_ramdisk setup, you can just install GooManager, select Flash ROMs and the app will ask if you have a custom recovery. Choose to install one and it will install the latest TWRP for you. I have TWRP 2.4.3.0 since last night without having to install another kernel.
