Hello !

For me, beta 11 is very smooth everywhere. Better than the other betas even on stock browser.

FYI i'm on XXKI4 and I use Nemus Launcher.

The 2nd core looks to start more often as in b8 but It doesn't means it gonna drain more battery. Will have a look at my battery stats today.

Sent from my mobile phone
[Galaxy S II Original Android Development] gokhanmoral:
no, it is still 70 but I decreased the lower threshold to 15.

if second core becomes active (which is less often with 70), it stays active longer.

I will investigate the reasons of that lagging.

it is fixed in v2.2
[Galaxy S II Original Android Development] kva:
2.2b9 + 2.2b11 defenitely has lag sometimes on 'home screen'.

2.2b6 have no such lag.
[Galaxy S II Original Android Development] sierrafox:
nice work gokhan, but i've recently noticed something odd about jerky video playback (mkvs, camera recorded videos etc, a variety of codecs and bitrates) in 2.1.1 and all the 2.2 betas (no ov/uv, independent of scheduler and governer). the last known release which doesn't do this is 1.8. not sure if it's due to memcard reading issues or ... i don't know, my knowledge isn't that great lol.

any chance you could have a look at this? thanks again
[Galaxy S II Original Android Development] cheewaca:
Another thing that happens with siya 2.2 is that I have less coverage than other kernels.

For example, with stock kernel, speedmod... i always have 3 lines of coverage. With Siyah 2.2, in beta 6, beta 9, beta 11 and the same place, i have 2 or less lines of coverage and sometimes when people call me the phone appears as if off.
[Galaxy S II Original Android Development] :
Nothing to do with kernel. Sorry to dissapoint.
[Galaxy S II Original Android Development] extract1:
I'm using I9100T and it works great :cool:
[Galaxy S II Original Android Development] cheewaca:
May not be the kernel but it is rare that only happens with siyah... at stock values with stock rom.

edit:

The version of stock rom is XWKJ3.

[Galaxy S II Original Android Development] cheewaca:
Don´t make me laugh please. I tested it several days before post it.
[Galaxy S II Original Android Development] gokhanmoral:
it may be related with dvfs locking frequency.

previously, locking level was CPU_L1 or CPU_L0 (same as stock rom)

but since we have 2 more higher freq. steps in this kernel I changed them to CPU_L3 and CPU_L2.

I don't want to use anything above stock frequencies. but I may modify that part a little more so that higher frequency will be used if you have overclocking.

EDIT: increasing it is already safe as the cpu won't go higher than the policy max. I will change it back in the next release.
[Galaxy S II Original Android Development] TecQuality:
@gokahn: take note that i've just noticed that we can flash your kernels easily w/odinmobile ... superb! :)
[Galaxy S II Original Android Development] veyka:
I have been watching a lot of video with my sgs2 via mhl (my computers down due to part failure) and i have had 0 video lagging problems with any of the betas, this is outputting to a 1080 screen.
[Galaxy S II Original Android Development] energie:
how to ? :|
[Galaxy S II Original Android Development] sierrafox:
ok thanks for that (i think i understand). but i'm using hardware decoding with these videos (presumably being driven by the GPU), would dvfs locking affect that? just wondering if it's I/O-based (any changes to filesystem access?) or CPU/GPU-based. in any case, thanks for taking a look, and hoping reverting to CPU_L1 or CPU_L0 fixes the problem.

that's strange, but it's really obvious whenever i watch anything (locally on the SGS2). i've just noticed that you're running cognition, i'm on checkrom revolution HD v2 so i might try switching roms to see if it makes a difference...
[Galaxy S II Original Android Development] gokhanmoral:
right, it may not be directly related with CPU but setting CPU level to 0 in stock kernel leads to setting the bus freq to 400MHz without considering the bus load. that may be the reason of the lag.

anyway, I will double check those parts again.
[Galaxy S II Original Android Development] spaxx24:
Gokhan, do you still use Touch X-Power ROM or what do you use?
[Galaxy S II Original Android Development] gokhanmoral:
those who can notice lag with beta11: can you please comment on beta12?
[Galaxy S II Original Android Development] gokhanmoral:
I used 4 different roms in this week :)

it would be more but I was a little busy so I did not flash miui.

right.. I have to update my signature...
[Galaxy S II Original Android Development] Dark_Lord0122:
the lag is gone in beta12 :) i noticed it in some games and while opening any text/sms
[Galaxy S II Original Android Development] shahulvm:
beta 8 and beta 9

Beta 8 and beta 9 had a good combination of battery life and performance....but sadly swithing boat to speedmod kernel as siyah kernel is taking away battery charge by display...if only it could be auto brought down, as ther is always an option to increase it...

I know there exists a Screen shade or screen filter app, but they are not auto started and also stay annoyingly on the status bar..

Siyah, am sure kernel can be tweaked to lower the brightness, as the users would always have a chance to increase it
[Galaxy S II Original Android Development] veyka:
I tried checkrom rev3.x before cog and had trouble with it, ymmv of cause, cog has been great so far!
[Galaxy S II Original Android Development] sierrafox:
i was on cog 1.51 before moving to chkromrv2, might move back depending on how it goes ...

@Gokhan; 2.2b12 seems to have fixed the jerky video playback, not sure if it's placebo because i'm sure you'll tell me that you haven't changed dvfs locking at all lol. anyways, nice one, and thanks for the fix!

ps: no lagging in zeam scrolling
[Galaxy S II Original Android Development] veyka:
Jerky scrolling in xda app/reader seems to be fixed in beta 12!
[Galaxy S II Original Android Development] jdmcivic:
is it just me or that beta12 seems to.have changed my display abit?

i believe this is the smoothest version ever on my sgs2
[Galaxy S II Original Android Development] cheewaca:
In b12 less lag but still present when i change between home and aplications menu.
[Galaxy S II Original Android Development] bgx:
Report no more lag with b12 here too! Very smooth! Now would be nice to lower display brightness per kernel and script!
[Galaxy S II Original Android Development] gokhanmoral:
working on it...
[Galaxy S II Original Android Development] karlesg:
Which are the stock Samsung charge_current values?

In latest beta 12, I see 750 650 450 by default.

In previous betas it was 650 550 450 by default.
[Galaxy S II Original Android Development] ebliss:
b12 is still the same. The governer changed to ondemand by itself once I turn off the screen. The min freq gets changed too, from 25 to 200.

edit: after a few reboots, it is back to normal. weird.

jdmcivic, nope. still on vr2.5.
[Galaxy S II Original Android Development] jdmcivic:
are u by any chance using gingermod rom??
[Galaxy S II Original Android Development] sadonlyone:
indeed, on b12 less lag related to b11.

still b6 it seems to me a little bit faster for now. a second opinion would be helpful.

how to reproduce on opera mobile web browser (not opera mini!):

- open opera mobile app

- touch opera icon (right bottom corner)

- notice a little lag when menu shows up first time.

on beta6 there is no lag following steps reproduced above.
[Galaxy S II Original Android Development] iamsmallpang:
my white gs2 stay to beta 9 , it work great because i have not to charge battery 2 days , battery level above 60

then black 1 just flashed to beta 12 , it work smooth , setcpu can set profile ( max 500 min 100 ondemand)
[Galaxy S II Original Android Development] kalpik:
Definitely less laggy than Beta 11, but I've seen smoother Betas :D
[Galaxy S II Original Android Development] spaxx24:
Sigh. b6 is the new b14... :(
[Galaxy S II Original Android Development] droidphile:
Gokhan, some lag in app drawer using lulzactive, hotplug, 25-1400. (like beta 11)

This lag disappears:

1)if i use ondemand/ondemanx or 2) use single core mode (even on luzactive)

Scenarios for lag: (only while scrolling slowly and gently, NO lag while scrolling fast)

1) lulzactive-hotplug 2) smartassv2-hotplug 3) luzactive-dual core 4) smartassv2-dual core

I think the 2nd core lower threshold is still 15 like beta 11. And the "stubborn" 60% threshold which governs scale-up/scale-down for lulzactive, and "ideal frequency" concept in smartassv2 using 2 cores is what's causing the problem.

Could you increase the lower threshold or provide an interface for upper/lower threshold in the upcoming Siyah App.
[Galaxy S II Original Android Development] gokhanmoral:
thanks for this comprehensive comment.

did you try to modify sched_mc value (setting it to 0) and try the same laggy governors?

I will increase the threshold in the next release and also provide an interface to configure it.

EDIT: oops. I made a typo and typed "ifdef" instead of "ifndef". cpu threshold values are set to default in beta12. not 15-70 but 20-60. they were supposed to be defaults in darkknight edition :)
[Galaxy S II Original Android Development] BoneMo:
menu+back button problems

when with b12 i set in Settings>Device Settings....Notifications to enabled...then backlight of buttons menu+back stop to work when display is on...and cannot turn on backlight back ---backlight is forever turned off:(----only factory reset helps :(
[Galaxy S II Original Android Development] bragon2010:
Very laggy beta12 with GalnetICS and ADW Launcher. In desktop scroll and apl drawer.
[Galaxy S II Original Android Development] droidphile:
Thanks in advance for threshold interface :)

Tried sched_mc=0 and even 1 for luzactive and smartassv2. Same lag in hotplug and dual core. No lag in single core. Beta 9 was butter smooth on app drawer scrolling.

I guess, increased "active" and "deactive" threshold is better for our phones. 25-70 may be...

EDIT: Setting to 0 causes random freezes as well. (Because there's no load balancing, and since it takes more time for cpu1 to become inactive, may be cpu1 is overloaded)
[Galaxy S II Original Android Development] taqri85:
Excellent kernel. Very very stable indeed.

[Galaxy S II Original Android Development] :
No lag with standard launcher, why do u use adw when miuis one is already great and hw acc afaik?
[Galaxy S II Original Android Development] goose2600:
I Gokmam, I have the same lag in app drawer on CM7 (nightly 115).

Even for me, it decreases using single core mode.

With beta 10 and 11 I had a strange kind of lag.

While phone was in standby and start ringing I had to wait it rings a couple of times (the screen was black) before I can answer sliding lockscreen.

This lag disappeared on beta 12.

Maybe it helps someone.

Bye

[Galaxy S II Original Android Development] id10terrordfw:
I'm loving this kernel, amazing performance with Oxy 2.3.2 (customized to my liking). One question though, any chance we can remove the GPU FPS cap, like the i9000 and i897 Captivate have? It is odd benchmarking them both next to each other and seeing the Captivate hit 65fps in Nenamark and AnTuTu while my GSII stays at or under 60... :D
[Galaxy S II Original Android Development] gokhanmoral:
yes, but I am also using different values for screen_off (35-90) to decrease second core usage when the screen is off.

I thought it would be easier to extend tegrak's code.

but maybe I should use the same location as Samsung did...

or maybe both? :)
[Galaxy S II Original Android Development] droidphile:
in Samsung location, beta 9 has it 15-70.

I thought you lowered it to 15 from beta 11 only.

Can't wait to try changing screen on & off thresholds in beta 13 :p

[Galaxy S II Original Android Development] :
Hi gokhanmoral, it would be nice if you could add these lines in your post-init.sh script to make it able to remove /mnt/emmc :

mount /system -o remount,rw

rm -f /mnt/emmc

mount /system -o remount,ro
[Galaxy S II Original Android Development] olifee:
Any chance we can lower the GPU FPS cap, i.e. cap it more? :P

The GPU cap is very nice to conserve some power / lower GPU temperature (as vsync on a desktop). Imagine you are playing some OpenGL-game (which might not implement some cap itself) that keeps throwing as many frames as possible at you (which might be 120, or even more).

With our display, you may not even notice the difference between 30 and 60 frames (I guess), but your GPU will have to render twice as many frames, screen will be refreshed twice as much etc.

So unless you have a cat and develop an app to entertain it (after all, it appears this phone can do anything with gokhanmoral around ;) ) we should not need more than about 30 frames/s effectively.

However, if gokhanmoral decides to change something with the cap, I guess he might as well make it configurable ;). At least, a pure benchmark-encouraging change which might even consume power does not make sense to me.
[Galaxy S II Original Android Development] Guetta1:
beta12 is o.k., but beta6 is the best !

please fix the jerky video playback, it's really annoying.
[Galaxy S II Original Android Development] xuxuzao:
is it possible for miui user to have great battery life as other roms using this kernel?

with normal use i cant go trough 20 hours
[Galaxy S II Original Android Development] gokhanmoral:
thanks for help :) I didn't have time to explore what is wrong.

I forgot that rootfs is already mounted readonly when that rm command is executed.

now I will remove the second known issue from beta13 :)
[Galaxy S II Original Android Development] BoneMo:
emmc

in beta 13

removed /mnt/emmc 30 seconds after booting

so now where will we find emmc(real plastic SD) ?? /sdcard/external_SD ?

PS: now with beta 12 i also have /emmc folder linked to plastic sdcard

oops.. I forgot to fix that problem and I've just restored my phone back to samsung rom.

you'll have to wait for beta14 for that.
[Galaxy S II Original Android Development] gokhanmoral:
if you are having problem with internal sd you should try flashing a stock rom by repartitioning and then flash cm7 back because I have absolutely no problem with internal or external sdcard with beta 12 and 13.

but I did not test them with 115, I made my tests with 111.

[Galaxy S II Original Android Development] goose2600:
Internal and external sd card works fine for me on cm115 and b13 (without to flash stock rom or anything else)

The lag continues with beta14, Galnet ICS, ADW Ex and SmartassV2.
[Galaxy S II Original Android Development] Auridran:
That makes sense, because SmartassV2 has been laggy for a very long time in this kernel. Use another governor.
[Galaxy S II Original Android Development] CamoGeko:
Try lulzactive. :)

I have lag also. It does not happen with beta9.
[Galaxy S II Original Android Development] droidphile:
Gokhan, any specific reason why sched_mc=1 in Beta 14? :)

Sorry for repeating the same thing again, but beta 14 has those lags as well. Even though thresholds are now 25-70, 2nd core is active more often compared to beta 9. (To reproduce: screen off-wait for 2 mins-screen on-open 2nd core app immediately)

Whatever magic you did in beta 9, please do it in beta 14 too!

I will try different even higher threshold and report back about the lag.

EDIT: Tried 30-70, 30-80, 35-70, 35-80. (using sched_mc=2) Still lags. Gokhan, may be something else is overriding this limits and kicking in 2nd core too often. Half-heartedly, switching to ondemand on beta 14 until 2nd core stays calm in upcoming releases :)

The same here lulz 100-1000, sio, some uv on Tricky's optimized MIUI ;) no lag.
[Galaxy S II Original Android Development] gokhanmoral:
smartass or lulzactive may have lag sometimes. they are not meant to provide the best performance. if you want no lag, user performance governor.

there are some tweaks that I apply sometimes that feels those battery saving governors have less or no lag but there is no magic tweak that makes everybody happy. when I tweak them to have less lag with lulzactive on your device another device has another kind of lag (browser, appdrawer, 3dgames...etc)

so, I will try to close to stock in the next release and leave that tweaking part to rom developers/users via sys interfaces.
