Hey Guys,
This is the discussion thread for the DM Kernel.
You can discuss here about the best config's, performance, and any other non-development related queries or topics.
Please feel free to discuss about anything and everything related to Android / Kernels / ROMs... It will be a place where I can gain knowledge from you guys
Based on the discussions, I'll create an FAQ's and Interesting Post's list for everyone's reference.
Thanks to M90 for the idea. :good:

Yes, The DarkKnight is rising again

Hi Dharam,
I'm on Checkrom V7 and wait for a DarkKnight LQ5 Kernel
Do they really stop developing for SG2?

I think they really stopped,leomar wrote "no more s2 developing" on CR forum ,so...

can anyone recommend a governor best suited for heavy use? smartassv2 doesn't really handle resource-intensive apps very well.

Hi,
i wanted to thank you for this fantastic Kernel.
Using it ont CM9 RC2.
I'm coming from Siyah, and Fluxi, but your Kernel just blows everything away. Best Battery Life of all.
And with the upcoming fixes, especially BLN, it will be even better! Good Luck with your exams! And keep up this Good work.
Adding some Screenshots of my Battery Stats, and still 30% left(kernel default settings):
Edit: Added 2 new Screenshots, resulting in a Screen-On-Time with 5h 11m. I'm very happy with that.

Hi i use siyah with miui i want to install asnet and darkknight!
I like to know if darkkn. is for battery saving or / and preformance ?
I like to play gtaIII and other games so preformance and stability is important anny one has exp. or a tip ? tanks

First try the default settings. If they are not good for your usage, you can try to overclock to 1200 and to change governor to ondemand or pegasusq..

This was my first full cycle with DarkKnight v1.9.2, and the SensatioN ROM 3.5. And these are my results.
On the phone i was basically using chrome and whatsapp. I have no widgets on my homescreen and used the default kernel settings without changing anything. Note that i have a different non-samsung battery from "anker" with 1900mAh.
I think these are pretty decent results for the first cycle so keep up the good work
Ill continue to test your kernel, maybe also with different roms like cm9 rc2.

This is another one of my longest screen on time. The uptime is just 7hrs+ tho, I think.
Ondemand & sio
Auto Brightness
200-800mhz

Hey, i can't post in the development section, so i'm asking in this thread:
flashed 1.9.2 today and can't disable the LEDs. if i disable them in the system settings they stay disabled as long as i don't lock the screen. after unlocking they are enabled again. hadn't that problem with 1.8.
cache and dalvik already wiped.
any suggestions?

How do you guys get such great battery with high screen time? I have brightness set to auto. Whenever I have the screen on I can see my battery % drop very quickly.

[POLL] Which CPU governor do you use the most?

I know polls existed like this before but I was curious which governors are most commonly used in my gingertiny and incredikernel kernels as there are quite a few options though looking at the list not too many. I didn't put performance on the list even though it's an option in my kernels or at least one of them as it's not great on battery. Feel free to post comments about why you choose it. My choice is actually smartassV2 but there are other good ones as well.

I voted for lag free, but smartassV2 is a close second. I have always used smartass and smartassV2, untill lagfree was introduced. Lagfree just seems to have a little better balance between speed and battery consumption, at least in my opinion.

Been using sa2 but switched back to lag free and all is back to being smooth on ics linaro.

Try it but I always though sav2 was fine. The issue may be voltage.

Sav2

Good read on Gov's.nice explanation of how each Gov scales the CPU under load/idle
Which i personally found helpful since i wasn't sure what the difference between each gov was. Of coarse excluding the obvious ones powersave/conservative etc

Thanks for the read - It's tough to wade through all the differences all over the web, so seeing a single spot for all the info like that is great.

i use smartassV2, it seems to work better than the rest do for me

Using lazy on ics and jb roms, seems just as good as sav2 but with better battery.

How Important is it to change the I/O
After you choose the governor how important is it to choose the right I/O.

It may be worth giving interactive another chance in the latest incredikernel releases.

Deadline, noop and sio are about even. Noop may be a bit quicker.

Both smartassv2 and lagfree have worked well for me. If there is a difference, so far I haven't been able to tell

Where can I get CPU governor lag free? Is it compatible with miui gb?

Logcat for Team Union Rom

Sorry, I dont have enough posts yet to post in the dev thread so hopefully someone will add this to the Team Union Rom thread for me.
Basically, I installed Team Unions Rom after performing full wipe/cache/dalvik and format system.
The rom installs fine but I'm getting random reboots and occasionally it shuts down.
No apps are force closing and it never does it while I'm using it, but can often do it only a few minutes after I set it down beside me as I hear the Samsung boot noise and look down to see it booting.
I've never looked at a logcat so not sure what to look at.
To try to resolve it I've reflashed, and flashed full/small/extreme all with the same problem.
I'm going to try Paranoid Android Unofficial now while I'm waiting for N8010XXALGC_N8010BTUALG7_BTU.zip to come down from Hotfile. Then I'll try going back to stock to see if I have any issues.

Are you having M8010/N8013?
then you need to change CPU governor to "Ondemand", this should solve the problem.

Yep, I'm N8010.
I tried searching thread for "shut down" and found nothing.
I've just installed Paranoid Android so I'll give that a go later.
Is that a known bug?
Thanks for the help,
Conor

Yes its a known bug, i also had it with Cyanogenmod, if you'll have it with Paranoid, try change governor.

go to settings then tap on SET CPU..tap auto recommended then change the SCALING to on demand

Scaling equals the governor.
It is known that on all wifi devices you MUST use the ondemand governor with all the roms made for N8000 else you'll get random reboots.
No problems at all when you switch to ondemand (standard is pegasusq).

Done. Nice one!

I tried out your Set CPU setup and it was kind of bad, because of the lagfree governor,i did some research and i found a thread explaing all governors and lagfree doesn't actually make your phone "Lag free" it saves battery by throttling it down to the minimum clock speed for a simple task but when it needs more juice it will throttle higher providing more performance, but it doesn't work well as i have had regular force closes with apps like FlipBoard, Falcon Pro and messaging (which force closed alot)
Thanks anyways for contributing

Awesome stuff man.
I decided to install Lupus Kernel (720p) and I failed so many times because ADB wasn't detecting my phone in fastboot and reason is because i use a mini usb hub (it connects into 1 hub and makes 5 hubs) so adb and fastboot dident have direct conntact with my phone and today i had a strange feeling and pluged it in to main usb port on my pc and it worked like a charm,i flashed lupus and i am enjoying it.
I think it is considerably faster that Doomkernel and smoother AND reliable,i used to get random force closes every now and then but now its super smooth and Touch screen response seems to be 100x better,
I also tried out your setup and shadowgun,Dead trigger(ULTRA GFX setting) and MC4 runs smooth at around 50 FPS

Glad I could help!

SetCpu for the Razr M

guys I am rooted on stock 4.1.2, unlocked bootloader an' all that jazz, i used to use setcpu on nexus s and the old droid milestone, does setcpu work for the razr m? any good working profiles without the reboots and stuff ?

All of the 4.2.2 roms I have tried have a settings option called Performance that lets you set the min/max CPU speeds, switch between different kinds of governors, and play around with RAM management settings.

i am not on 4.2.2 nor do i intend to go, all i wanna know is that if setcpu is stable for the razr m and what profile should be best for good battery life

I use row or noop for my i/o scheduler and on demand for my governor and setup works I used to use it but I like no frills better

So far the clocks have stuck Meaning once you set a clock its stays there, doesn't reset to default. As for govs and I/O, I use msm-dvcs as my gov and row as my I/O. Msm-dvcs will shut a CPU core down when not needed

That's nice... but shutting down a core... isn't that harmful for the phones life or something? Just asking to increase my knowledge that's all...

Unfortunately I don't dabbled in profiles as I personally find them unreliable. I just stick it at a certain clock and set my govs and I/O. If you want to know my configuration, I set my clock to 1350MHz and min to 384. The gov and I/O I've already mentioned.

thanks bro, that's really informative, i think ill solve that out but once again, battery life with speed is what everyone's after, yes the M has plenty of oomph under the bonnet but clocking it down will save battery yeah?
the profiles you have set are stable enough? no random reboots or lags?
