[Galaxy S II Q&A, Help & Troubleshooting] droidphile:
You want to limit your screen off frequency to 200 or you want to use only smartassv2 as the screen on governor (without screen off governor) ? I don't get your point.

1) If screen on = lulzactive and screen off = smartassv2 100-200 then when screen is off, smartassv2 scales down to 100 very quickly. If you're playing music, then depending on demand, it scales upto 200 and there won't be any stuttering.

2) If screen on=smartassv2 and no screen off governor/profile, then like previous case on screen off, smartassv2 scales down to 100 mhz quickly. (And when screen is on, it scales up to 500 mhz quickly and then ramp down or ramp up depending on the demand. This way, there won't be any lag when screen wakes up). Now if you play music during screen off, the frequency is ramped up depending on demand and there is no upper limit for frequency when screen is off. So you can not guarantee that cpu uses at max 200/500/1000 or whatever during screen off when there's load. (like music playing)

To sum up, if you like luzactive as your awake governor, and you don't want music to stutter during screen off and don't want delay while waking the screen, use smartassv2 as sleep governor with lulzactive. As simple as that.

Hey all :)

I decided to post this here so the main thread stays clean.

A new feature of 2.2 is the mounting of NTFS drives, which is very cool. I'm wondering if this can be achieved for the external SD card too? Can it even be done or it's an Android limitation?

Thanks :)
[Galaxy S II Q&A, Help & Troubleshooting] olifee:
Technically that's possible (with a script, you can already do it yourself).

However, please rethink about it: Do you really want to use a journalling filesystem on an SD-card? It will decrease its lifetime and the benefits are really small.

A filesystem like ext2 should be much more interesting, as it will be faster and put less strain on the SD-card. And it does not have all those limitations NTFS brings about ;).

For now, this also works with a script (you could put it in init.d).

hi,

i am a new user and got my sgs 2 in october. i read much about sgs 2 and i want to try siyah kernel 2.2. now i use xwkj3 stock rom and stock kernel which i flashed it with odin from the intratech post. i also rooted the phone with cf-root and doomlord's easy method. my question is that i can use siyah kernel with the xwkj3 stock rom or i need a custom rom for this kernel? stock rom for me now is ok. i also read in the syah kernel developer post that the kernel supports dynamic hotplug. i need to instal from market 2nd core app and that is all? i want to ask that using smartass v2 governor which has a profile for deep sleep and using 2nd core app which shutdowns 2ndcore when screen off is compatible, and work combined to save more battery life.
[Galaxy S II Q&A, Help & Troubleshooting] droidphile:
1) Yes, you can flash Siyah kernel on your stock KJ3 rom. Siyah is a unified kernel that can be flashed on Samsung official roms, samsung based custom roms and aosp roms.

2) Dynamic hot plug mode is the default/stock behavior where in second core is active only when load on first core reaches a certain threshold. When load is reduced, second core is automatically turned off. You can use Tegrak 2nd core app to switch it to Single core mode (only one core active all the tim), Dual core mode (both cores active all the time) or leave it in dynamic hotplug mode for the stock behavior.

3) Smartassv2 is a battery friendly governor, it doesn't have a screen off profile. But it make sure that frequency is scaled down rapidly to lowest frequency when screen is off. Also, in the kernel, (while screen is off) 2nd core is turned on only when load=90%. So you can be sure that when phone is idle and screen is off, only one core is active until deep sleep.
[Galaxy S II Q&A, Help & Troubleshooting] pissyhun:
thank for your reply droidphile

so if i want to use only 1 core when in deep sleep and both cores when screen is on kernel does this by itself and i don't need 2nd core app for the hotplug setting.
[Galaxy S II Q&A, Help & Troubleshooting] droidphile:
As to Kernel default, you can be sure as long as you're not using phone when screen is off (like playing music), only one core will be active.

If you want to use two cores all the time when screen is on, you have set to dual core mode in 2nd Core app. But this will override the kernel threshold settings which is meant only for hotplug mode. Also, using 2 cores all the time will cause battery drain.

I suggest you leave it in hotplug mode and kernel will look after switching cores when necessary.

poor battery life with Siyah 2.2nolog

Hi,

Since today I was using Siyah 2.1.1 and I had a good battery life (nearly 2 days).

I've installed today Siyah 2.2nolog and setcpu. In 30 minutes my battery passed from 48% to 44% while I was doing nothing. As I am writing now, it's 41% :(

Setcpu is set with ondemand governor, min 200MHz max 1200MHz.

I had understood that Siyah 2.2 disable the second core in sleep mode, am I right ?

Please help me, don't want to go back to 2.1.1...

As I am writing this message, in 2 minutes battery went down to 40%... It's just crazy !

Please help me

Thank you

[Galaxy S II Q&A, Help & Troubleshooting] droidphile:
Ondemand in 2.2 final (and 2.2 rc3) has a

sleep profile. With max screen off frequency 500 mhz. So it is same as ondemandx.

When you're using smartassV2 as screen off profile, the governors are

conflicting

1 - Does anyone have freezing device when disconnect via usb with RC buids?? I'm having that problem with v2.0 i just want to know if the problem are also in 2.1 RC builds

2 - If i flash a 2.1 RC build do i get any OC or UC by default?? (don't want that!!!)

3 - What are the default settings for CPU and UV with samsung stock kernel??

You can always download voltage control and look at your GPU settings from inside there. Voltage control can also save a boot config file into init.d folder that is really handy. It has everything including CPU steppings, voltages, GPU steps and voltages, governors, I/O schedulers and charge rate. Basically all in one.

You can also generate one and then edit your GPU settings from there. Reboot and then check voltage control to see if your problem still persists. Dont forget to remove your prevous 96_GPU file.

No need. You can just uninstall voltage control. But many people have mentioned that setcpu consumes quite abit of battery.
