OnDemand and Intellidemand both seem a bit laggy to me as well.

I have not used the Lulz Gov. But the Lagfree seems to work good for me. Although CPU0 seems to shoot high then slowly descend and CPU1 is offline until load and then maxes until the load goes down and then goes back offline.. Like I said it works for me though im not 100% sure if this is how this governor is supposed to behave.. Smooth with what seems to be decent battery as well but to early to judge on that..

I am using System Tuner 17200 Max/192 Min With lagfree governor. Also used the -12.5 button in voltage control in the system tuner app. Pressed it a total of 5 times so UV @ -62.5 *Odd Number and I am not sure if its even taking but I have not had any reboot/freezing/or sleep of death..

As far as quadrant goes, like i was saying before, I am seeing in the 4K+ score with this set up. Best I've had.

I know not a real help, but trying to give feedback on my experience.

I love the BLN but switched back to stock kernel due to touch being unresponsive sometimes and lulzactive governor being stuck at 1.5Ghz.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
1.2 Updated..

1.2 Update up:

(read the changelog in OP)

Summary:

* restored the Stock governor and I/O scheduler.

* scaling enabled so it should not stick to one frequency.

* BLN & touchkey interaction fixes..

I am going to stick with the stock and all the remaining gov's will be there as optional for people to play around..Eventually I would like to remove some of the unused one's to trim the kernel, I will give it a few versions..

- And folks BLN enabled and touchkey off behavior will be undefined. As it does not make any sense, please spare a post..

I have no idea what you are talking about? If you don't describe what the problem is, i don't see how anyone can help you.

I am not experiencing any such thing..but then I am not a big video player watcher, camera shot movies, videoplayer launched via browser videos all are working fine..so you would need to flash back to stock rom (ucle2) and then install the kernel, or attach the logcat and kmsg..so I can point what may be wrong if the info. is available.

1.3 added

1.3 Up..

* the max. allowed freq. is enabled again..

Since the default governor is on demand (since 1.2) which is what the stock uses, it will use the extreme frequencies...which mean 1.728MHz, please use any of the other governors, for better battery life or lower the max. with any app or use the shell to lower the value.....

P.S: Please read OP (for other changes or general info).
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Pseudonym117:
well this may be fixed now, but its on my mind:

in 1.1, a few governors have strange issues. smartassv2 sometimes would work in a semi-normal way, but others (earlier today) got stuck at 1620 MHz and never wend down, except to go to deep sleep. not even to 192 when the screen was off. and the max was set to 1720, so i dont get why it would be doing that... id get it if it were at max frequency, but near max? thats just strange. also, lulzactive seems to toggle between 1500 and sleep. is that just what it does? ondemand also seems laggy, as does badass and lazy, but i have never used those before, so i assume thats what they do.

sorry if this is fixed now, but i felt a reply may be helpful.

edit: also, could you up the OC to 1.8 GHz? my phone was able to run it on da_g's old GB kernel and itd be cool to have. ive never done any kernel compiling or i would try that my self, as it doesnt seem too difficult with the source.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] kishke:
Moahn, Can you please uploaded a kernel version where SmartReflex is turned off?

I have an issue that when the screen is off and the phone is idle it loses signal.

After doing some googling I found out its a pretty common note issue from patch 4.0.4 and the only fix beside setting min cpu to 700+ Mhz is to install a kernel with SmartReflex off, which cant be done manually without reverting on reboot.

I'm still on stock UCLE2,Kernal. when I'm trying to use hotspot tethering it works until the phone goes to sleep. I also have noticed that if I have several apps needing update in market and select to update all. Only the first couple get downloaded the rest get cut off as soon as phone goes to sleep This should not happen especially since I have the market app set as enable wifi when screen off in Juice deffender app.

My Question is first is this a common problem with 4.0.4?

Second if so, can you fix this behavior in kernel land

SO glad your on the job mohan :good: Your current kernel work and the features you,re bringing to the ICS. SkyRocket Have been long anticipated. Keep at it, and Siyah won't have nothin on CYMBALINE

Hello, I appreciate your work a lot and I love what it can do but I am running SKYICS 4.2E-17 and whenever I use your kernel it makes the screen lag and not respond well. As soon as I revert back to stock kernel the lag is gone. Is there any fix? I really just want to use your kernel for BLN control....

Hi Mohan,

The problem I am having with bluetooth is I am getting disconnect/connect issue in my car. The pairing work fine but every few minutes my phone get disconnected and then it reconnect right away. I dont have this issue with android 2.3 but every ICS leak and even the stock ICS Rogers ROM cause this problem. I am not the only one, there is a lot of people complaining on this problem.

Thanks.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
Kernel is Rogers Compatible

Ok..Folks, I have updated the OP to indicate the Cymbaline kernel is Rogers Compatible. I have based this on:

* The official Rogers ICS kernel, it looks they are using the same offsets as ATT now. GB version kernels had a different offset. This was my main worry..

* I have scanned the ATT & Rogers code block for differences, they appear to be minor and deal with some initialization differences on the peripherals.

The only issuse *some* users may have is dependent on the H/W version of your device. In case you do have such a thing, pm me your "dmesg" (adb shell dmesg > dmesg.log)..

Also, I got a bunch of requests for feature adds, please I will get to them as time permits..
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] slam666:
Hi Mohan,

For Rogers, we just install Embryo 3.2 then flash this kernel?

For my bluetooth problem, is there anything I can send you to help finding the problem (if I still have it after installing your ROM and Kernel)?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
The kernel is ROM independent, you just need an ICS based firmware. As far as the bluetooth issue, I believe this is somewhere in the F/W. Just make sure you are running the latest version of BT F/W on your car. I have a Ford Edge (running my touch 3.0.2, I think, which has major bt fixes), i am not experiencing any issues, despite my gazillion kernel flashes :) (maybe thats the cure). All I am saying is there is another variable here one must consider. I believe ICS roms they have modified the bluetooth stack (or upgraded it), so that's why it may work in GB consistently. What is strange is not everyone on ICS appears to be having this issue..Yeah a logcat would be helpful..
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
Are you on 1.3? One thing you can do is since we have the stock governor scale down the top cpu speed (if on 1.3) using any of the tools..and see..I am running 1.3 on a UCLE2 based ROM..and I have to admit never seen the phone more responsive (of course at the expense of batt. life, will see)..

- Also, check if anyone else running the kernel on the same rom having any issues..the ROM author is your best bet..
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] jstrayy:
Yea, another member told me to go back to stock and that was the fix for the lag. I would ask the ROM author but they are not too friendly in the thread. I will just have to go without, thanks a lot for the speedy response and thank you for not bashing me :)

UCLF5

SO....i'll be the guinea pig, I loaded the Kernel on the UCLF5 leak, it won't show in the "About" section of the Settings, but I am able to OC up to 1.72Ghz and use all Governors, the only problem im seeing is the Syscrtl tweaks, i'm assuming those don't work because the Kernel was based on previous builds, is this an update we will see in the future?

Till then, i'll keep OC'ing till 1.4 :cyclops:
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
CYMBALINE-1.4 up..

1.4 is up. I would recommend everyone to upgrade to it.

* scaled down the default max cpu scaling to 1.566 Mhz. So this should give much better battery performance and some slight tweaks added to the ondemand gov.

(you can still oc/uv)

* More govs added for people to play with..

* Also made it configuration compatible with newly released UCLF5 rom.. I played with the stock UCLF5 kernel for an hour, sammy did a disservice did not appear to have fixed any of the major issues with ucle2, thank god for cymbaline..:) (I didn;t install the rom though that's tomorrow)..

I will put up a voting thingy to eliminate least used govs, so I can trim the kernel down..

I am on the new UCLF5 and flashed this kernel 1.4. Set CPU is doing the same thing for me. Set to 1566 but stuck at 1728. Even after reboot with set on boot checked.

I just installed System Tuner and am seeing the same problems. Maxing at 1.24. CPU1 is showing offline the whole time.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] ReedX50v:
Try a different governor and/or app. Not all of them play nice with various apps.

SetCPU is working fine for me with ondemand, badass, and smartassv2.

Alternatively, download Terminal Emulator in the market and see the following thread for info on how to manually set the various features.

[REF][TWEAKS] Kernel Governors, Modules, I/O Schedulers, CPU Tweaks, AIO App Configs

For Example:

SU

echo "X" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

echo "X" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

Where the Xs are your desired frequencies. The settings won't stick on a reboot (I think) but you can at least see that the OC/UC is working.

If you are really feeling randy, it shows you how to write a script to make your desired changes...

Overall, System Tuner has been incredibly flaky for me.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
OK General Info

Some of you know this, but those who don't. I don't know the internal of the app, but the standard sysfs interface to query your cpu frequency is (cmd line):

#:cpu0 min freq
adb shell cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
#:cpu0 cur freq
adb shell cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
#:cpu0 max freq
adb shell cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
#:cpu0 current set governor
adb shell cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
#:cpu1 min. freq ONLY IF ONLINE (default is hotplug mode, online when needed)
adb shell cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_min_freq
#:cpu1 max. freq ONLY IF ONLINE (default is hotplug mode, online when needed)
adb shell cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
#:cpu0 show all available govs.
adb shell cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
#:cpu0 show avail. freq.
adb shell cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies

- I do NOT KNOW how each app. set this..and if set through multiple apps (which I am guessing people have done)..who wins..

To permanently set this w/o any apps. create a shell script and use the above interface to set. and drop the script in /system/etc/init.d (chown root.shell, and chmod 0755)..

* DVFS has been enabled, which should only affect the default governor (ondemand) none of the other ones should be effected..

ALSO, all this is related to 1.4

I think that the touch response had been better with the 1.5 dev version. I started using this with v. 1.4.

Thanks for testing folks, here is another one, if the testers can jump on it:

* This one has the siyah tweaks for the ondemand..

* And, the booting to max. freq was annoying me, this version, locks the boot to 1.52 the stock max. (NOTE: only when booting.) So people noticed that 20s cpu in the max (1.836GHz), yup when cpu is brought online it inits to the max. set. Also, as the old jungle saying goes "not all cpu's are created equal", so at least this should let everyone at boot up the rom...

CYMBALINE-1.5-DEV-2-cwm5.zip

That's it for some time now..let everyone run their tests.. Also, I still believe ondemand (the one stock uses) is probably going to be the best allround dd gov. so I am going to leave it that..vary as little from stock..and oc/uv'ers can anyway change them...

Okay Mohan, I've been running 1.5 Dev-1 since shortly after you released it and it seems at least as stable as your other releases. :good:

1.836GHz is more stable than it was for me on the GB kernels. Ran quadrant with Ondemand, Interactive, Badass, and SmartassV2 governors and got 4300+ scores with all and no stability issues. (using deadline i/o scheduler).

Sleeps like a baby, dropping only 1-2% per hour.

Also, I haven't had time to test each individual frequency, but a global voltage drop of 12.5 mV is also stable for me. So, there's at least that for a starting point.

Have you considered messing with the GPU and system bus frequencies and their scaling? I've seen mention that limiting the GPU a bit has some substantial power savings.
