guys have you noticed stuttering/lags in games with 5.0 or 5.0.1 version ?

I have Asphalt 7 installed on my S2 running latest CM9 nightly. When I play the game (quick race) it stutters from time to time, especially on turns. I tried everything stock, which means:

governor: pegasusq

cpu: 1200 Mhz

option 1: GPU: stock without VPLL

option 2: GPU: stock with VPLL enabled

Anyone has an idea or can advice me something to get rid of stuttering? To be honest I do not know whether the game sucks or I should tweak kernerl a little bit.

I do not want to overclock my CPU, however I was wondering about GPU settings.

Can you please let me know how GPU thresholds work? In Stweaks we have 5 thresholds (step 1 to step 5). Both steps 1 and 2 have condition that says: " GPU threshold to jump up from first to second / second to third" which is set to 80%. Does it mean the GPU freq will jump from first to the second step when 80% threshold is reached and then with another poll it jumps from second to third when load is still equal or greater than 80%?

OR it means that the second threshold is skipped and GPU jumps directrly from first to the third step?

Hi,

Was it a question or just a statement?

Nevermind, I can only confirm - the option "Remove root" in STweaks is quite sensitive - if you use it, it remove your su binary + SuperSU app from the system. If you forget to tick before an option "Auto-install root" then you loose your root for good and to have root again you have to reflash a kernel.

In fact, if setting it @450mah, it'll charge at that level. However if setting it to more, not matter how (500, 550, 600, etc..) it will be charging @650mah... Either USB or AC. Is this a known bug or did i forgot something somewhere else? I'm wondering since in Dorimanx kernel it can go up to 750mah (but still charging @650mah)...

The game itself is full of lags. Read the reviews in the Play store. It lags even on the S3. Don't bother with tuning the kernel & all the jazz ju for this game.

Ummm.. That's the options intended function. What did you expect when you hit that option? It's functionality remains the same since the inception of the option.

If you would have even bothered searching once in the Dorimanx thread instead of spamming both the thread with the same question again & again you would have got your answer form GM himself who took out time form his precious schedule to give an answer but apparently the quote "No pain no gain" is lost on you so here goes.

Our IC only supports 90, 450 & 650 mAh so no amount of software coding is going to change that.

Now I know your going going to come back with a rude reply because I was rude to you but I'll just you know that you deserved it & if you wish to continue this please PM me.

I have flashed 5.0.1, all seems ok for now, im on xwlpx, because on xwlpy lost signal when talk with anyone.

vpll work for me( but its not activated by default), games work ok. At 333mhz battery is not that hot.

But lost CSC( is unknow) ( dont know if because of siyah or new room), but i flash again hidden+cache in mobile odin, csc is ok now.

And mass storage not working at all now, on my PC at least, try force mass storage, mtp, etc, in my computer appear 2x removable disk, instead of one, i cant acces neither.

kies does not sees my phone. Only option work is to TURN on USB Storage, that one work..maybe ill fixed it in time...

No freeze, no nothing, baterry seems ok.

One small bug: in stweaks at BLN tab, i need to set LED TIMEOUT to 1 sec( default its use room....), if i leave default led are light up non-stop, even if i set 1.5 sec in my android settings.

If you find this bug, you know how to fix it.

Settings in Stweaks remain after restart( someone on v5 siyah forum talk about that).

A lot of new options on this kernel.
[Galaxy S II Q&A, Help & Troubleshooting] Debadatta:
For LED, select "Always off" in system settings and select desired setting from STweaks. Will work fine.

And as for Mass Storage, works fine here bro. Try a different USB port. Kies will recognize as soon as its correctly connected. Or maybe you have some driver problem?

[Galaxy S II Q&A, Help & Troubleshooting] bogdan1980:

2 h 30 min screen time and down to 50%., brightness 30%, GPS,3g,sync off, no Facebook, no nothing.

4.1.4 is better at battery but I like 333 mhz on video. My gpu don't like 400 mhz on any voltage.

Liter bench score on xwlpx compare to xwlpy.

But to many bugs on lpy.

I didn't modify it to detect Kies. I modified the aesthetic part of the framework :p

If my ROM gets detected with the modified framework, stock framework will definitely get detected :p

kernel 5.0i: landscape mode notification not working properly anymore

kernel 5.0i: rotating the phone stops working properly after using the phone for a while after each boot: keyboards don't stretch horizontally on whole screen in landscape mode. I observed that with Swype, Swiftkey.

Also Nova launcher gets confused when this problem stats to happen and in landscape mode it does not display the dock bar on the right anymore, but instead it displays it at the bottom.

Once I upgraded the kernel to 5.0.1, the problem disappeared.

I only listed this here in order to make aware the creator(s) of the kernel to avoid this bug in future version.

GM, thanks for this great kernel.

I would like to report that since I've installed Siyah 5.0.1 the S2 is becoming very hot when using WiFi, it doesn't matter if I'm browsing or using Twitter app or Facebook app, it becomes hot a lot, more than it used to do with v4 of the kernel. Do you have any advice on this? something I should configure in the STweaks ?

Phone: GT-i9100

Kernel: Siyah 5.0.1+

Compilation: IMM76D.UHLPV

Thanks.
[Galaxy S II Q&A, Help & Troubleshooting] Tungstwenty:
Do you have the device connected to a PC?

I have noticed that my phone also gets very hot sometimes, and it appears to happen when I reboot it and leave the cable connected. Perhaps if the kernel was flashed, I'm not sure.

Or it could be related with Mobile ODIN, since the situations I remember were after flashing newer kernels (Mobile ODIN) and restarting without unplugging.

When this happens, I disconnect, turn the phone off, and after turning on the problem is gone.

It doesn't get hot for me (running Resurrection Remix 3.1.2 with LPS on my SGS2).

However, talking about WIFI, the WIFI was a bit unstable on my phone with 5.0i (especially the connecting phase, whenI had to try at least twice each time when I wanted to switch it on), but now seems stable with 5.0.1

Are you sure it only happen with the 5.0.1?, because that kind of behaviour can be inducted by your gateway rules/or network environment.
[Galaxy S II Q&A, Help & Troubleshooting] Tungstwenty:
Neither does mine ... normally.

But if I leave it connected, transfer the TAR of e.g. a new Siyah version, flash the kernel with Mobile ODIN and let it restart still connected, it will then start heating and when I notice it I'll need to disconnect and shutdown before starting again.

At least that's my impression, but I don't guarantee this is a sure receipt to replicate that symptom.

[Galaxy S II Q&A, Help & Troubleshooting] It_ler:
If you don't need the additional/higher GPU frequency steps, then keep vpll mode disabled (like default).

But some users experience stuttering in resource-demanding graphics/3D video games ... or even when playing HD videos.

And the additional/higher GPU frequency steps lead to a better performance (if they are stable on the phone) - measurable in graphics benchmark/test apps.

In this case, enabling the vpll mode can help.

"Deep Sleep" Governor

There are some things that you do not understand :

- No governor are used when being in deep slepp <= This is a reality, there is a reason it is called "Deep sleep"

- In your initial post you certainly mixed two things "screen off" governor... and "deep sleep" "governor" ...these are two differents things, the first one exist the second don't... ! The phone do not go in deep sleep as soon as the screen goes off...

=> Useless discussion now, facts have been explained

- No governor when deep sleeping

- Nothing more than 650mAh can be achieved

=> "Features" can't be achieved

[Galaxy S II Q&A, Help & Troubleshooting] It_ler:
Yes, wifi is mainly kernel-related AFAIK.
[Galaxy S II Q&A, Help & Troubleshooting] Socotroco:
I found out that it would might be VPLL MODE in the GPU settings at STWEAKS, having that setting enable made my S2 get hot after some time with screen on(5 or more minutes). I have disable that setting and now the S2 is working at normal temperature for it (28-30 celsius). I have also changed the STEP5 in the GPU frequency to 267MHz as I don't play graphic intensive games(the most "intensive" I play is Angry Birds). Also changed the GPU voltage for STEP5 and set it to 100mV. Basically the STEP4 and STEP5 are the same: 267MHz/1050mV.

This simple tweak solved my issue with temperature and the battery is also having better performance.

Sched_mc

Of course sched_mc is to be used in dual core mode ! This is explained in the link i gave.

"We have at least 3 different solutions for decreasing a core load:

sched_mc and sched_smt with load balancing

cgroup + cpuset

cpu hotplug"

These are three methods that can't be mixed or you'll get a strange behavior. About using sched_mc in hotplug mode, i do not know what would be the result... i would keep away from using it.

My reply was about sched_mc and consumption : 0 is worse than 1 which is worse than 2 : 0 is a kind of "all core on", 1 is a kind of "hotplug" and 2 is a kind of "hotplug" with "fill CPU0 first"

How can i activate bln for sms. (stock rom)

In the STweaks, bln is activatet.

thx mike
[Galaxy S II Q&A, Help & Troubleshooting] Many40:
You just answered yourself if SCHED_MC is usefull or not for our S2 (your sentence in red). Why? Gonna explain you ...

It's obvious that analyzing pros and cons for activation sched_mc inregards to battery power saving shouldn't be done without considering CPU HOTPLUG kernel's tunable.

In short, we have following possibilities in S2 / Siyah:

1. CPU Hotplug - ON

"When hotplugging knows when and how to hotplug In and Out second core, there's no need of another logic to do the same and cause conflicts. Hotplugging does load balancing already by taking care of thresholds, run queues, process priorities etc"

So, no need for sched_mc=1 neither 2, It should be disabled -> Sched_mc=0.

2. CPU Hotplug - OFF, SINGLE CORE

. Sched_mc doesn't make sense - this is the logic for multi - core architecture.

3. CPU Hotplug - OFF, DUAL CORE

. Sched_mc exactly makes sense and if it's set to "2" (load balancing) probably (haven't tested that) will save some power BUT ONLY in comparison with situation when on DUAL CORE mode sched_mc is set to "0" AND DEFINITELY NOT in comparison with setup when CPU Hotplug - ON. Why? Mainly because in DUAL CORE mode (2nd core always ON) phone will never reach CPU idle states (default AFTR/LPA) -> states between screen-off and deep-sleep, so that it will never go to DEEP-SLEEP.

Answer yourself if this would be good for power saving of our phones :)

[Galaxy S II Q&A, Help & Troubleshooting] Sun90:
use 'NS TOOLS' app from stores for the same:)
[Galaxy S II Q&A, Help & Troubleshooting] Honusnap:
I used my phone in forced dual core mode for like 6 months but i do not really know if it reached intermediate low power mode like LPA or AFTR. There was not a big difference in battery consumption vs Hotplug, was smooth with no problems, but the idea of having this second core powered for nothing ... i do not like it .. :)

In forced dual core, there is near no spikes to 1200Mhz, there is more in hotplug mode... of course it also depends on the governor parameters, so it's difficult to compare.

The best for our phone is to use hotplug (most of the time), removing sched_mc from the kernel would be a good idea, rewriting the hotplug module would also be a good idea. The scheduler should be aware of the hardware topology (energy envelope, what cost what in which conditions, do not know the real word in english)... to send the task to the correct CPU, being aware of what it would "cost".

Of course the Hotplug module should also be aware of this topology.

Hi guys so far 5.01 works pretty well and it might just be me but has anyone else experienced issues with smooth scaling on ondemand? I have it set to 800 and it used to work perfectly but now it (as judged by cpu spy) it almost always ignores 800 and jump to 1000. Am I the only one experiencing this issue?

Is the easiest way to restore 5 cpu steps (Samsung default) via init.d scripts or is there an easier way I don't know of?

Hi all,

i have a couple of questions, which i hope someone can help me with.

1) Signal drop on 4.1.5: has anyone got an idea on why it happens? i do get every now and then signal drop ("insert sim card") which i can only fix by rebooting... btw, has someone experienced this on 5.0.1? what's the last version that doesn't suffer from this?

2) i tried installing 5.0.1 on my phone, but even with default (GM's one) configuration (no UV in the GPU and CPU) i get freezes. these happen in non gpu intesive games (e.g. PES 2011 - with malistatus i see it run mostly at the lower gpu step). any idea? is it only because of my hardware that is not compatible with the latest kernel or is it sw related?

Hi,

Just reminded myself one possibility which I'm testing right now and seems it works.

Executed thich command from terminal:

kmemhelper -n smooth_level -t int 11

Should also work as init.d script.

It changes smooth scalling level from 800MHz to 500MHz. What with MAX scalling freq set to 1000MHz makes sense. I'm observing this in Voltage Control app and now seems CPU more seldom jumps to 1000MHz and usage of intermadiate frequencies is bigger.
