Even without UV and OC ?! ;)

Chrono added the 300Mhz step.. here is good to know at wich Voltage.. it's nothing new that we have different CPU Qualitys.

I've made many Test'S about OC, UV... u know that. And at the End for now I've made scripts only for Screen off UV, so 200 - 400MHz @ 1V and i faced in the last few days the "Blackscreen issue" + Problems with no appeared Clock in Lockscreen and after that the Clock was + 1 the Widget..

So if i don't delete the double Clocks on Lockscreen, I've one Day 6 or 7 Clock pages.. And somethimes the Device don't respond for 3 Minutes, and sometimes the Kernel resets.. so reboot beginns at CM Bootlogo.

I will try to find out what is the reason for that.... i hope it's related to GPU or CPU UV !

When i've results, i will post it here.

Report stock rom 4.1.2 - latest esperimental build - 200/1000 mhz - pegasusq/vr

My phone is smoother than previous build and all is fine until now. I'll test again tomorrow
[Galaxy Ace II Android Development] fluffi444:
Yes - Completly without UV - no CPU / no GPU! Removed all my uV weeks ago to eliminate possible reboot reasons...

I use only standard which Chrono set in Kernel (according to you I guess)

Exactly the same here - Blackscreen with no response and after quite long time (3 min sounds good :)) - reboot...

After that pegasusq was setted as Gov - But I used last time pegasusqplus...

Will now stay at pegasusq with our values and see what happens.
[Galaxy Ace II Android Development] muop_92:
I also have **** issue. Clock stops running after a long time screen off
[Galaxy Ace II Android Development] ace2nutzer:
Ok Guys, keep calm, now we know that, we will fix this as soon possible.
[Galaxy Ace II Android Development] Master-ZizO:
[MENTION=5695278]ChronoMonochrome[/MENTION] i think Up/Down arrows for Mobile Data disappears with your kernel.. any fix for that ?
[Galaxy Ace II Android Development] judas1977:
that newest kernel looks really good, but I have annoying stuttering all the time (slim 4.3.1).

but maybe I try to port some improvements to stock kernel:)
[Galaxy Ace II Android Development] ChronoMonochrome:
Yeah, MCDE driver from CoCore is really awesome https://github.com/ChronoMonochrome/Chrono_Kernel/commit/6200f4a02165c597f159f42369fa24ac765aac7e

Looks like s6d "black screen" completely disappeared, and I no longer notice screen tearing during watching video with HW decoder.

Btw I didn't noticed sound shuttering on Abyssplug, PegasusQ(tested 200/1200 MHz and 100/400 MHz) and Interactive(works with 200/1200 and 100/600 MHz).
[Galaxy Ace II Android Development] judas1977:
@up

oh, sorry, I meant screen tearing in last post. it's rather massive one. I have standard LCD driver. last time I saw such tearing in polishvidka's kernel made especially for s6d driver
[Galaxy Ace II Android Development] ChronoMonochrome:
:eek: didn't notice any tearings. I have ws2401 screen driver too.
[Galaxy Ace II Android Development] pedroleon99:
No tearing here. Of course, i have standard LCD driver

Confirmed the first impression.

No reboots and no problems at all

Good work [MENTION=5695278]ChronoMonochrome[/MENTION]
[Galaxy Ace II Android Development] exodius48:
Which version did you use?
[Galaxy Ace II Android Development] judas1977:
i believe you guys, but it doesn't change the fact that I have it:)

maybe I'll try to install it once more (I think there were no tearing when I installed it on bit different ROM...)

and that's kernel compiled by me, so maybe... (toolchain difference or sth)

edit: still massive tearing: (
[Galaxy Ace II Android Development] xkvegans:

Can you upload it for me please :D

or give me link for the thread

Thanks before
[Galaxy Ace II Android Development] ace2nutzer:
Oh.. i think we have 2 diffrent Bugs with Clock / Lockscreen Clock and Blackscreen after waking up the Device..

The actually Bug is: Clock STOP working after long time screen OFF. - I don't have this Bug, because i'm on older Build with Stock Kernel.

The older Bug with Blackscreen, and disappered Clock fron Lockscreen ----> i have this... and [MENTION=4962787]fluffi444[/MENTION] too ?!

It looks like that I've found the Problem.. from Yesterday till now.. i don't have any Bug... but for sure i'll wait another 24h Hours if the Problem don't came back !

@ All with the actually optimized pegasusq Gov. !

I've optimized this Gov. for min. CPU 200Mhz.. please don't use other Freq's.

I don't know if Chrono has merged this Tweak too:

echo 100 > /debug/prcmu/ape_opp

To Check if this is Fully working:

After the Phone is on for minimum 2 Hours and u have it used normally.. check in /debug/prcmu/ape_stats if the APE OPP 100 shows 98 - 99 %.. if not, u need to make init.d script with the command above !

After that, the oiled KitKat project V1.0 if working correctly !

Also i reccomend this: (For Powersaving)

echo min=100000 > /sys/kernel/cpufreq/screenoff_cpufreq_limits
echo max=400000 > /sys/kernel/cpufreq/screenoff_cpufreq_limits
echo on > /sys/kernel/cpufreq/screenoff_cpufreq_limits

does latest f2fs kernel have option to convert ext4 to f2fs???

f2fs conversion guide must use zwliew kernel though...
[Galaxy Ace II Android Development] danny19901:
Flash any F2FS kernel then reboot recovery and option is there you don't need zwliew kernel to convert

Thanks for report. It may relate to 3.1 or 3.2 patches. I'll try revert some changes in networking.

Upd. Ok, I see it also may relate to some changes(not in networking) which already reverted. I'll make new build( here is uploaded builds for 4.4.x and 4.2.x) for stock and see if it help.

Aospa is superfast, with or without chrono kernel but has some random reboots occasionaly

random reboot I think it is a problem with the SDcard, I have often encountered before, especially after swap memory.

[Galaxy Ace II Android Development] Andrewbons:
Dunno what's wrong with this kernel...

First time i've installed it, we all had recovery reboot bug. Since then i'm stucked at the recovery with a black screen, randomly it lets me in. I've changed rom, kernel, flashed with odin, repartitioned, but since then i cannot enter on recovery mode easily: i have to try and reboot lots of times untill it lets me in.

Another weird thing:

I've always used CM 11 by rox, with minimum 22 hours battery life with my daily usage, and i was very happy with that. Since i've installed this kernel (i love F2FS) my battery last 6-8 hours with the same usage. The weird thing is that restoring my old CM 11 backup i still have that very same battery drain. Same things with all the others roms. I bought my Ace II on April 2014 and all the apps i found say my batter is still good. I tried stock JB, cm10.2, cm11 and i cannot even reach 12 hours

If someone has any idea about what is appening to me, please help me

Yes, without data arrow its hard to notice is the connection work properly...

Btw i like chrono cross..its one of the greatest game on playstation...

Its hard to find a game have such quality this day..
[Galaxy Ace II Android Development] ChronoMonochrome:
Afaik data arrows were removed by CM team. Maybe anybody knows which CM builds have this?
[Galaxy Ace II Android Development] ace2nutzer:
I never seen Arrows on CM .. but very very small arrows in Signal Bars.. but very little.
[Galaxy Ace II Android Development] judas1977:
stock tc kernel has the arrows since long time ago.
[Galaxy Ace II Android Development] riyosakura:
Its removed on aosp 4.4.x. But not on CM.

CM has implemented data arrow since june or july.

[Galaxy Ace II Android Development] ChronoMonochrome:
Okay, I'll look into this soon.
[Galaxy Ace II Android Development] fluffi444:
Maybe in the F2FS enabled recovery itself. I think this was taken from codina as it is.

Hi, ChronoMonochrome,

I have flashed yesterday your new kernel from the file chrono_kernel_r1.2.1_4.4.x_cwm_ext4.zip on my phone Samsung Galaxy Ace 2 (GT-I8160, Codina). But there was next information about kernel version in the phone after flashing this new kernel:

"3.2.0-Chrono-r1.1-g000d0d2-dirty chrono@Monochrome #0 Sun Sep 7 20:48:37 MSK 2014".

What's up? Why the kernel version number "r1.1" in my phone after flashing your new kernel is not "r1.2.1" as in the kernel zip-file? And why the date is Sep 7?

Thank you in advance!
[Galaxy Ace II Android Development] ChronoMonochrome:
Hi. I just forgot to change version number before I compiled those kernels :silly:
[Galaxy Ace II Android Development] riyosakura:
Hi there..

Ive problem with bln_kernel_wakelock after installing this kernel on liquidsmooth 4.4.4.

Reboot solved it..its always occured after charging the phone..any suggestion..?
[Galaxy Ace II Android Development] ChronoMonochrome:
Very weird behaviour... Check value in /sys/devices/virtual/misc/backlightnotification/wakelock if it will happen again. I'll remove this interface in next version.
[Galaxy Ace II Android Development] riyosakura:
Value is 1.

So what the best thing i can do until next version released?

Im stuck with f2fs and cannot revert back to default without formatting. [emoji20]

And the wakelock will drain my batt.

I hope you'll release next kernel as soon as possible. :D

I forgot to mention im using 10 sep build. I'll try another build.
[Galaxy Ace II Android Development] ChronoMonochrome:
Try to disable bln from NT settings, if it will not help, type

echo 0 > /sys/devices/virtual/misc/backlightnotification/wakelock

Sorry for the inconvenience.
[Galaxy Ace II Android Development] riyosakura:
I try previous build 1.2.1 version.

And there is no bln wakelock.

So changing value on bln wakelock will actually fixed the bln wakelock itself?

Thaanks for you fast responses. :D
[Galaxy Ace II Android Development] lumufei:
Thank you for your work, this kernel super smooth with F2FS, and i want to konw which cpu governor and I/O scheduler is best ? thanks:fingers-crossed:(i am in AOSPA)

No. It did not helped.
[Galaxy Ace II Android Development] judas1977:
I'd say that it's in one of three first commits AFTER releasing R1.2. R1.2 works good, but kernel with Chrono sources (with additional 3 or so commits) has that massive tearing... I don't know which commits are "they" because Chrono reworked that sources later i think...
[Galaxy Ace II Android Development] ChronoMonochrome:
I know, this https://github.com/ChronoMonochrome/Chrono_Kernel/commit/6200f4a02165c597f159f42369fa24ac765aac7e commit causes tearing on 4.3 :\ . I'll make new build for 4.3, without this commit and will see if it helps.
[Galaxy Ace II Android Development] BlueZ-:
I'm not sure..the ext4 version is the one named twrp? Because for 1.2 version of the kernel there is the ext4_cwm one..

i download this kernel chrono_kernel_r1.3_4.1.2_twrp.zip

twrp in the name thats mean it have a TWRP recovery with it

i have stock kernel and a temporary CWM can i use it to flash this kernel
[Galaxy Ace II Android Development] ChronoMonochrome:
You can flash it via temporary CWM.

UPD. I found time for new build for 4.3. https://drive.google.com/#folders/0B_OwIFfWQnj_U0k5MTNPYmJ6X3M (r1.3.3)

Can anyone check if there is display tearing?

P.s. It's also bumped to 3.2.6 . Damn it, it was not such easily as expected. :)
[Galaxy Ace II Android Development] Andrewbons:
Lots of battery drain with the last kernel. I have too many kernel wakelocks.

[Galaxy Ace II Android Development] arroyo:
1.3.3 for Android 4.3 has not got any screen glitches. No screen tearing.
[Galaxy Ace II Android Development] riyosakura:
I think f2fs take more ram than ext4.

Is it true or it just a bias??

For all with reboots and Gov. Interactive - Use another Gov. (PegasusQ is recomended - well optimized now by [MENTION=5840412]ace2nutzer[/MENTION] and [MENTION=5695278]ChronoMonochrome[/MENTION])

I had everytime probs with interactive... Stock CM11 as well as Chrono's kernel...

OK - Interactive is quite nice and fast - But reboot sucks as well... :)
[Galaxy Ace II Android Development] MarquesYOLO:
PegasusQ is better than Intelliactive? I'm with Intelliactive in CM11 and i'm very happy with it.
[Galaxy Ace II Android Development] fluffi444:
Then stay with it. If it works over few days without reboot then its ok. Its faster than pegasusq buts eats more battery....
[Galaxy Ace II Android Development] muop_92:

[Galaxy Ace II Android Development] ace2nutzer:
Strange.. for me it's Smooth :o and have good battery life.

We can tweak the Gov. a little more, for more Smooth, but then it will drain more Battery....

I Think we have already the Right Balance beetwen Performance / Battery.

Yeah.. it's Known.. we will try to fix this may be in next Build.

( It's not only a Problem of too low Screen OFF Freq. ... )
[Galaxy Ace II Android Development] fluffi444:
Comparend to Intelliactive every other governor is laggy :) Only 100% preformance is faster...

Inn generall Intelliactive rises the clock to maximum with every little fingertip and lower it slowly depending on the further use of the Phone.
[Galaxy Ace II Android Development] shaqman89:
How's the battery performance? Just by how it works, sounds kinda heavy on battery.
[Galaxy Ace II Android Development] ChronoMonochrome:
Strange. For me it works properly with whatever CPU settings( of course, with max CPU freq at least >= 300 MHz :) ) which I use. CPU prefers to stay at 300 MHz if min freq is same(but with min freq @ 100 MHz it stays at 600 MHz).

[Galaxy Ace II Android Development] ace2nutzer:
Hmm really strange... but for screen ON I've optimized pegasusq for min. 200Mhz ... if u use other freq. it will not work properly.

If u prefer to use for ex. min. 100Mhz.. u can do this.. without problems... but u need to adapt. the "up_threshold_at_min_freq" Value :)
[Galaxy Ace II Android Development] ChronoMonochrome:
I think it's really unnecessary if screenoff max freq capped to 400 or 300 MHz.
