Siyah itself won't cause any problems ie. wiping data\restore nandroid\format.

Configuration for alarm to work with UC at 25 ?

@pickachu

A few days ago someone was mentioning again the issue with the alarm not ringing when underclocking below 200 and you said it wouldn't happen if the scaling was set appropriately on pegasusq to allow it to ramp up so the alarm rings.

I remember you mentioning before something on how to configure that properly, but despite my searches I didn't manage to find that information.

Could you post a link to where I could find those instructions or explanations? I'd like to reduce min to 25 but without risking being late again :)

[Galaxy S II Q&A, Help & Troubleshooting] Tungstwenty:
Thanks!

I had a look at the main script, bolt_siyah and also screenstate_scaling.

Here are a few comments, do you mind clarifying some of these?

On the main script there's lots of settings which I'm far from understanding :) but I guess they're applicable and will try them as is.

The noatime mount part will only change mounts /acct, /dev/cpuctl, /system (??? it's ro...) vs my siyah 3.3.2 defaults - is it worth keeping? /system is ro, and the 2 others are not physical devices.

Also, I see that my default mounts in addition to noatime also have nodiratime on sdcard, external_sd and secure/asec, but not on /data. Should this be added as well to prevent additional writes? Or noatime already implies nodiratime?

There are 3 lines active (with a comment before stating that they're tests), sending NO_GENTLE_FAIR_SLEEPERS, NO_NEW_FAIR_SLEEPERS and NO_NORMALIZED_SLEEPER to /sys/kernel/debug/sched_features. Should I keep this? Won't it disable the new GENTLE_FAIR_SLEEPERS that I activated on ExTweaks?

On bolt_siyah, the only 2 settings is sending 0 to sched_mc (which is the same as I have in ExTweaks) and 3 to cpuidle/parameters/enable_mask, which I'm guessing is binary for AFTR+LPA which is also default in ExTw. So I think I won't need this script.

Then there's the screenstate one which if I understand correctly will sleep 2s between loops and adjust the governor's settings to the ones you mention, without changing it (it's "").

The sleep times will likely be bigger if the CPU is in deep sleep, I assume. And in that case, if the alarm goes off and the CPU awakes with the screen off and quickly on, the script will take at least 2s, but could eventually be 4 (?) to execute the governor adjustments for screen on.

My question is if the on/off settings are both good enough that I can set minfreq to 25, max to 1000 or 1200 on NSTools and the phone will still ring when the time for the alarm comes (apart from all the improvements in the other areas on the main script, which are lots and lots of them).

(BTW, you have a typo on line 452 - there's an i from when vim was already in insert mode ;))

On the 2 dirty_ratio & vfs_cache_pressure sections, the values seem to be a bit off against the comments, especially on the screen off block.

And finally, about data corruption:

Siyah's defaults are already nobarrier and commit=60 for cache and data. I think I'll skip the libsql patch for now in order not to have a higher risk of data loss.

In conclusion, excellent info on the scripts even if I wont use them all right not. I'll start by putting the main and the screenstate ones in init.d, with one or another change depending on your feedback.

Thanks again!

[Galaxy S II Q&A, Help & Troubleshooting] pikachu01:
Even if they are not physical devices, they are still touched when accessed. The noatime will help. About system, noatime will not do anything, but no harm in putting it in, though when you access /system in rw mode, it helps there. :)

noatime implies nodiratime.

Yes, it'll disable ExTweaks's GENTLE_FAIR_SLEEPERS. IMHO, all of those *_FAIR_SLEEPERS only helps certain tasks so that they are given more priority in CFS. My objective here is to make the CFS as fair as possible.

In Siyah, only GENTLE_FAIR_SLEEPERS is tuneable:

https://github.com/gokhanmoral/siyahkernel3/blob/update4-3.0.y/kernel/sched_features.h

The sleep will be 2 seconds flat, but the screenstate_scaling mechanism happens faster than that (try it). No, the sleep will be the same amount of time no matter the frequency.

Thanks for catching the typo :P Yes, I was using VIM. Yes, the 25MHz are good enough for screen on/off. Though, one thing I've noticed is that 25MHz is not good enough while viewing videos. You'll get stutters. My advice is to use 25MHz while screen is off while 100MHz minimum while screen is on.

Ignore the comments on the screenstate_scaling. I need to prune those. LOL.

The barrier and remounts were originally from ThunderBolt! :P The libsqlite is only compatible with Gingerbread. Don't use it!

I would prefer posting this on ThunderBolt! thread itself, but you've already posted here. Sorry if this was too offtopic.

[Galaxy S II Q&A, Help & Troubleshooting] Mutalisk:
If you disable second core, all hotplug mechanisms are useless.

But nevertheless, you can use both of these governors, so yes, you can stick to pegasus.

They just don't make much sense that way I guess... ;)
[Galaxy S II Q&A, Help & Troubleshooting] tlf55:

Edit: just to clarify:

I'm skeptical, because pegasus uses hotplug mechanisms as well, so not sure if it is a good governor without the second core, but you'll see if it is or not ;)
[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
The hotplug settings in extweaks are only there for the not multicore-aware governors (everything except pegasusq and 'hotplug' governor).

So if you keep using pegasus (which is hotplug-aware), it will use the second core if it finds need to, despite of the setting 'second-core-off' in extweaks

I'm testing 3.3.2 right now as opposed to 3.2.7.1 which I've been using for quite a while, and I'm still leaning towards 3.2.7.1

Battery efficiency on both are practically even, wifi in 3.3.2 is much better than it was on 3.3.1, but I still have the impression that it's a tiny bit weaker, and takes a bit longer to connect

3.3.2 tends to spend a lot more time on 500Mhz (minimum set to 100) as compared to 3.2.71 with exact same settings, which would imply, in the long run, 3.2.7.1 would be slightly battery friendlier

(so unless you're on 3.3.2 for the usb-mode settings, I think 3.2.7.1 is still a tiny bit better...)

edit: scratch that remark about spending more time on 500Mhz (both kernels about the same...)
[Galaxy S II Q&A, Help & Troubleshooting] Frozenthunder:
Hey guys,

I'm not sure if this is kernel related or if it's just a problem which only I have, but since 3.3.2 the charging animation when the phone is turned off changed. When I plug it in the battery symbole appears but then the screen somehow restarts and I see a different symbole which just shows a chargin animation and not the current charging level like it used to do.

Also, my battery gauge has been behaving a bit weird in the last time (jumping from 50 to 12%).This is all since 3.3.2. Not sure if this is just coincidence or a bug. Anyone else experiencing this?

Can someone with 3.3.2 please turn off his phone and plug it into wall charger and try it out?
[Galaxy S II Q&A, Help & Troubleshooting] Many40:
To be honest recently I haven't charged my battery when the phone was turned off, but I have checked it for you - after short restart of a battery symbol - the same battery symbol starts again with charging animation inside this symbol. Then after a while it turns off automaticaly. It pops up again if you press the power button. Concerning battery behaviour and battery saving I personnaly experience better conditions than I had with older kernels - no problems at all.

Edit: It is probably obvious for you, but did you do wipe cache and Dalvik before flashing the kernel - it helps often.
[Galaxy S II Q&A, Help & Troubleshooting] Frozenthunder:
That sounds like the same animation which I see. There used to be an animation where the battery was "filling up" the more the batter is actually charged. And below that were 5 dots which were flashing up from left to right. This seems to be gone now.

Edit:

Changelog:

-battery charging animation, service and lpm.rc from CM9

Looks like this is intended. But why did you do that GM? The old battery charging animation is superior in every way. Why did you give us this animation which is completely useless? I don't know the charge level of my phone now when it's charging while turned off.

I've seen you post this a few times now over the past couple of days.

It doesn't seem that anyone else is having this issue as it hasn't been reported by anyone else. I'm certainly not having this issue and come to think of it I've never even heard of it happening to anyone else in the whole time I've read the thread. It has to be the ROM, ROM\kernel combination or just one of those strange things that happen.

Have you tried everything you can think of to remedy it; wipes, resetting tweaks etc? If you have it sounds like you're going to have to do something a little more drastic such as wiping data and reflashing the ROM or perhaps another ROM entirely because like I said it doesn't seem to be happening to anyone else.

Basically, I like a more "dynamic" battery charging animation.

But I doesn't like the new battery charging animation as it is now on Sammy ROM, as I often charge my phone when it's turned off and I can no longer see when the battery is 100% (fully) charged.

[Galaxy S II Q&A, Help & Troubleshooting] #illidan:
Well it wasn't GM that wanted to change it but it was the CM team that changed the charging animation to the asop one

a few weeks back & since there were not changed to match those in the kernel, the charging animation just froze & the phone could'nt be switched on when charging so GM had to do the necessary changes.

For the gauge issue try resetting the gauge form ex tweaks.

It a known bug that when you change brightness the backlight keys will automatically turn on. All you need to do is untick & retick the below setting once again & the backlight will get turned off.

Yes for me time spent on 500mhz with pegasus seems huge as well and with it battery drain. I just reseted all settings(also cache etc) and took out battery for 5min to see if this will help... but for me it also spended almost 50% of time on 500mhz with screen off (and about 30 on 100mhz that i have set up as lowest frequency)! This was more "normal" on 3.2.3 and lulzactive, i had like 70% spend on 100mhz, i didnt try lulzactive yet on 3.2.4.

Also about issues with BLN... i have them as well, i am on stock XWLPD firmware (it was same thing on XWLP9 and 3.2.3) and i tryed probably 90% of combinations of all settings(always on/off in settings, and many of random settings in exteakes), BLN does not work for me for SMS/calls... but it works for example for mails. It seems like when you get SMS or missed call it turns on your screen and after BLN does not work, for incoming mails where your screen does not turn on it works. Anyone have a solution?
