BLN

Thank's for this kernel, finally BLN for my sgs2 with miui:p:p
[Galaxy S II Original Android Development] yahyoh:
same here but without sod alot of time happened with siyah when i turn off the screen the wifi will disconnect from the router and it see my wifi idk what the problem but no problem with cm9 default kernel
[Galaxy S II Original Android Development] bala_gamer:
Lol, if you have a desktop PC then it would be dead meat soon :D though you would have room for water cooling
[Galaxy S II Original Android Development] virland:
Which miui ROM do you use? Because I tried the kernel with MiuiSp v1.1 and my phone doesn't boot right after the Samsung screen it gives me black screen like its shutting down...

From my Galaxy to Talpatalk!!!
[Galaxy S II Original Android Development] cmvcarlos88:
Gokhan, don't worry.Neophyte told that we only have to add on build.prop any line that contains the word miui and will work. I will try it later and report if it works.

Just installed rc1... data usage page (Settings -> Data Usage) does not show or allow me to select warning or restriction levels. Reverting back to b7 works fine.

I am using XWLP3 stock, not sure if problem persists on CM9.

Attached image to show what I mean - the red & orange lines (in the image set as 432 and 232 MB) are not present when I use rc1. The screenshot is from b7.

Can someone tell me how to fix the problem with external sd??? I can't see anything! Thanks!
[Galaxy S II Original Android Development] spyrale:
I found out that flashing siyah rc1 on wanam lite 10.5 breaks something about usb mass storage, it doesn't work anymore, phone freezes and have to long press power button, no problem with cf-root.

Edit: Re-enabling MTP with cwm zip provided by Wanam himself fixes the problem.
[Galaxy S II Original Android Development] The_MutenRoshi:
There is any version with the best battery life?
[Galaxy S II Original Android Development] bala_gamer:
Either set it manually via extweaks or simply flash rc1 and select battery friendly profile in cwm
[Galaxy S II Original Android Development] bleuxeon:
I use Siyah since the 2 dot something under CM7.

Now under CM9, I have successfully flash each new versions without any big stability issue.

Except with the rc1:D

I have had 2 "half" reboots : the screen complety freeze and 15 to 30 secs later it reboot (its not a true reboot I think) just to the CM9 splash intro.:confused:

This is the very first time I see this using Siyah. It didn't happent to me since v2 under CM7.

Should I try to completly reinstall CM9 from scratch, then Siyha?
[Galaxy S II Original Android Development] Shm33g:
I also can't access my external sdcard [yes I know it's mounted at /emmc but it's just not there :p]

Also my storage settings crash immediately upon opening.

I'm about to do a full wipe to flash Infinitum Rom 0.6.6 and Siyah RC1, mainly because of glitchy bootups and the sdcard problem.

Edit: My glitchy bootup problem is similar to bleuxeon's, it hangs for 10-30 seconds with the screen on then reboots to the bootscreen, i think it is the bootscreen anyway as it is blank :/
[Galaxy S II Original Android Development] toxictoby:
what does this mode actually do to the phone ??/

thanks in advance
[Galaxy S II Original Android Development] BoneMo:
well i have opposite experience....can access external sdcard...i have installed some apks from it....

i can access storage settings

not having bootloops....everything is just ok

maybe it is ROM related problem
[Galaxy S II Original Android Development] luke05dee:
This kernel is like having a new phone, so many things to play about with, thank you :)

I'm so looking forward to being able to edit available frequency's, I always thought 1.5ghz was a good comprise between speed and battery :)
[Galaxy S II Original Android Development] Schindler33:
I think 800 MHz is a good compromise between speed and battery. Even most games do not lag. if you not game at all I think 500 MHz is enough. Personally,I don't see the point in overclocking
[Galaxy S II Original Android Development] The-Hulk:
I have just flashed rc1 on CM9 Nightly 02-04-2012, running very smooth, only problem is on my galaxy s2 the menu and back button dont light up and when pressing menu button no option to select settings. This is my first time flashing this kernel ao not sure if these are known problems.

Thanks for the work, and i am looking foward to your dual booting
[Galaxy S II Original Android Development] danielsf:
The backlights are know problem, they are fixed in the upcoming RC2 update :) I hope this helps you :)

[Galaxy S II Original Android Development] The-Hulk:
Thanks it was helpful, this is my first time using a kernel not supplied by cm9 and it is so smooth, loving it how have i missed this for so long.
[Galaxy S II Original Android Development] Shm33g:
Yeah I'm guessing it is, about to re-flash everything anyway, I hope they're compatible as the Infinitum ROM + Siyah is an amazing experience.

[Galaxy S II Original Android Development] yahyoh:
the boot animation is blank screen on HyDrOG3N-ICS with rc1

and i have wifi problem some times get stuck didn't connect to my wifi until i turn it off and on then it will connect
[Galaxy S II Original Android Development] fettkraut:
Using stock XXLPQ with Siyah v3.0rc1 and everything is really smooth and fast. No problems here except the issue with the data limit. But it is not really a big prob in my opinion.

THX for this great kernel and for your efforts...!
[Galaxy S II Original Android Development] AndreiLux:
I ran through the Pegasusq logic for some time now;

The conclusion is that it's a governor tightly tied in with the hotplug logic but at the same time totally independent of it. It's written to be used with quad core CPUs where it really shines as you can specify dvfs frequencies on each jump between running core x and core x+1, and also for also each jump between online counts select the latency/delay (If somebody can explain me the real meaning behind the nr_run_avg value, please do because I can't wrap my head around it).

The problem is, that I'm not sure if the usual hotplug driver should be even used in that case, and if it doesn't, then do we have a conflict with two things trying to control the hotplugging? Doesn't the other have to be turned off?

I don't see the benefit of it anymore on our device; the code overhead is bigger than the benefits from it, if any. The governor has a lot of debug and monitoring functions available, but we have to have something to compare to, to evaluate it. I ran several benchmarks with the same work-load and the end ended up with higher sum of high frequencies running on Pegasusq vs usual Ondemand. I tried to change the configurables to bring it down but I always end up with it several times higher residency time on 500MHz vs 200MHz compared to the opposite on the usual Ondemand. I can't explain as to why this would be like that, as the frequency scaling should be the same between the two, and only thing as a reasonable explanation would be additional overhead? Not sure.

Anyway, I don't see the point in the governor as it is now, for our "mere" dual-core device.

It also has some useful early_suspent and early_resume notifier code which changes the sampling rate and up_rate on either event and I don't see why that part couldn't be made useful and backported into the usual Ondemand governor.
[Galaxy S II Original Android Development] hanhav:
I get reboots with stock LPQ using RC1 that I didn´t had with beta7. I have no idea of the cause.

Edit: and touch is almost too sensitive, cant scroll widgets cause I have set some gestures in Go launcher and they always go on when scrolling. Not that big of a deal though.

Set screen sensitivity to 5 pixel but still too sensitive.

Well reboot is my biggest problem now :(

And by reboot I mean, phone turns off and on, not asking pincode.
[Galaxy S II Original Android Development] Happy_Jack:
I hope you don't have the same issue I did. Straight after installing RC1 and rebooting my external 32GB SD card was not accessible. Turns out the partition table was corrupt. I had to reformat and then restore the last backup from my PC. :( Try accessing your SD card in a PC if you can.

I am also using the latest CM9 nightly (1 April from Codeworkx) and the Galaxy Note USB Mount app. I couldn't say that RC1 was what corrupted my SD, it could well be coincidence, but I'd remind everyone to make sure your internal and external SD storage is backed up somewhere else when playing with experimental ROMs and kernels.
[Galaxy S II Original Android Development] whazi:
just to be sure i wont mess up with all files\config:

i just flashed last rc1, wiped cache and dalvik

resetted extweaks and used battery mod from cwm

what now? i can still move change governors and setting on extweaks\voltage control?

or that battery mod set all and i dont have to touch anything else?
[Galaxy S II Original Android Development] Happy_Jack:
I had one spontaneous reboot (an hour after stuffing my SD card, see above). I never saw either problem with beta 7 so I've reverted to that for now. It will be interesting to see if the problems reoccur with b7...
[Galaxy S II Original Android Development] Blindi1985:
I had same problem!

I think the problem is with the SetCPU profiles.

As soon as I remove the profiles, there is no reboot.

If they are activated, the arbitrary and irregular intervals reboots.

But i'm on latest CM9 from 02. April

I do have a PC,but it's a very basic HP notebook for the time being,no proper desktop rig with its water cooling etc.I have already fried one PC CPU though,although it was an old AMD Athlon 3000+.You know,one of the single-core 1.8GHz variant of about a decade ago. :p

Oh,don't worry,it's an old bootanimation known as ohmaingodzifuckedmyphone.I remember we had it in an early version of Siyah 2.Don't remember exactly which one.It's quite nice though.It offers quite a bit of that feeling of happiness when the device finally boots up. :p

At first I thought the battery profile in recovery wasn't going to help much but look at this! It would be at like 60% or less by now without your kernel!
[Galaxy S II Original Android Development] Tergon:
Screen shot crazy battery life, running Omega V6 ICS Syiah 3.0 beta 7+. UV as per disscussion a few pages back, lowest screen brightness for two of four I ran the test. Admittedly light use, more phone calls than I original wanted to make about 6, total call time was 27 minutes and screen time was just shy of three hours on time. Check screen shot.
[Galaxy S II Original Android Development] sorg:
Gokhan,

i've downloaded your sources http://github.com/gokhanmoral/siyahkernel3 and initramfs http://github.com/gokhanmoral/initramfs3.

Compiled using your default config by android-toolchain-eabi-4.5-77-2012-03-30_00-44-21-linux-x86.tar.bz2

Kernel doesn't boot :(

If i change initramfs to one from CF-Root, your kernel boots (but have issues).

In your build script i see you use some additional folders payload and recovery. Last line is commented out, but i'm not sure is it needed or not.

I've tried your pre-copiled Beta7 - it works.

How to compile your kernel?

I've compiled NEAK ICS kernel which works, but i don't like it because it doesn't support CPU frequency adjustment. Well, it pretends it support, but settings are not affected to real CPU freq.

So, i wanna use your kernel, but i don't know how to properly compile it.
[Galaxy S II Original Android Development] Sepharite:
Has anyone tried with the latest CM9 Nightly?
[Galaxy S II Original Android Development] Entropy512:
Those experiencing freezes or reboots - such reports are useless without providing /proc/last_kmsg after you've long-pressed Power to reboot the device.

gokhan - Check my repo, there are two hotplug commits that might help. You need them both - the first one is broken without the second. I didn't put them in master. They're also in the teamhacksung repo
[Galaxy S II Original Android Development] Entropy512:
I believe nr_run_avg is some average of the number of running threads. I believe it's also how stand-hotplug takes measures to only hotplug in the second CPU when there are multiple threads.

There's a big in it where it tries to hotplug the CPU with the fewest threads running to minimize task migration overhead - if it picks CPU0, you get the "faint of death" I mentioned earlier.

It's a difference from Gingerbread - that hotplugging code didn't take into account active threads at all.

Also, we have a few other choices of hotplug algorithms - one of them is tied into cpufreq, and instead of ticking on an independent timer, ticks whenever the governor makes an adjustment.
[Galaxy S II Original Android Development] Entropy512:
None. I'm 90% certain 9.7 was a frankenbuild hybrid XXLPQ/XXLPJ firmware. No source-based kernel will boot it due to the XXLPJ components. Update your firmware.
[Galaxy S II Original Android Development] rlorange:
In beta6 you could change the top 3 frequencies using tegrak Oct ultimate but something changed from b7 on and tegrak updated his app too so it doesn't work any longer. Shame

[Galaxy S II Original Android Development] droidphile:
O.K so trying to turn off a core when both cores were up and minimum run queue length = zero was the reason to weirdly turn off CPU0.

i have a slow 3g speed in all ics rom with SiyahKernel also but in gb rom with SiyahKernel 2.12 2.13 2.14 is very good about 4mbps but in ics only get 2mbps

i have try many tweak but i think its kernal releted

so plz any one can explain it thank in advance
[Galaxy S II Original Android Development] bajee11:
You sure it's not your modem? did you change it?
[Galaxy S II Original Android Development] ripalbaria:
no in both ics and gb rom modem is kl1

and other thing in stock gb rom i also get 2mbps speed but when flash a SiyahKernel speed go to again 4mbps i have try many times
[Galaxy S II Original Android Development] gokhanmoral:
which GB kernel are you talking about

2.6.13 or 2.6.14?

I wish I knew the reason of that boost.

I'd say it may be crc algorithm but we have the same one in ICS.

I'll try to find the reason, because the boost you are talking about is huge.
[Galaxy S II Original Android Development] nickwarn:
Im having the same issue. On beta7 and on RC1 i have read and searched and this is the latest post on the issue. No one else has this?

As soon as i flash another kernel CF, CM9 stock and Neak it works.

I read in post abovethat its was caused by gpu undervolting. I never undervolt anything so i read the changelog and feature list for Siyah in OP, and it doesnt say if it undervolts the GPU by default it just says that the feature of Gpu undervolt/Overclock is there. Just thought i post that the issue is still present (atleast for me).
[Galaxy S II Original Android Development] gokhanmoral:
you are right. I think it is designed purely for Samsung SLP Pegasus-Q (M0-PROXIMA) board which has quad core. (and I was wondering what q was.. it is Q of Quad :) )

and I guess there will be no other hotplugging mechanism other than the on in this governor. and probably this governor will be the only scaling governor present in that version as we have ondemand for ICS release.

maybe we can have an option to disable other hotplugging (standalone one) and modify this governor a little later.

as Entropy512 has pointed out there are some other hotplug options. I didn't check them yet but names look interesting. I think dvfs-hotplug is similar to the one we used before and there is another dynamic-dvfs-nr_running one.

by the way, Entropy512: thank you for the fix of that CPU0 unplugging. I think your last patch will fix all blankscreen and unexpected locking up issues.
[Galaxy S II Original Android Development] nickwarn:
Gokan, sent you a PM. Well done
[Galaxy S II Original Android Development] Karpfenhai:
Hi there,

after one day of testing i want to give a feedback about RC1.

As you all already know about the features, i will only bring up the issues i found.

- Undervolting: Works great with GB Settings, but 500 MHZ has a Problem, as soon as you go below 925 it will freeze the phone, why is that? all others, -100 is working so far.

- In low Power conditions, the phone freezes one time, means, less then 10 % left, wakeup from sleep and crash, rebooting, applying the same settings, no issue, goes down to zero with no freeze.

- Weird behavior, i use only 200 -800 mhz on my phone, but it jumps sometimes to 1000 MHZ still. its rare but it happens, any advice on that?

Settings:

cfq/ondemand

200@850

500@925

800@950

1000@1050

1200-1400 not in use

CPU Hotplug off (Use 1 core only)

loadh 85 - loadl 40

Screen Off max freq. set to 200, many many thanks for that, i missed it really!

GPU Settings @ recommended Power Saving options 100-160-200 @ 800-850-900

@ Ghokan, Many thx for your advice and support!

Iyi günler, regards!

[Galaxy S II Original Android Development] planetf1:
Just a quick thanks for building this kernel. As a developer also (though not in this area) I appreciate all the effort you're putting into getting to the bottom of the issues being found.

I did try rc1 with LP3 but after 3 reboots/dead situations I've gone back to stock/cfroot. HOWEVER I so your reminder of retrieving the last kmesg so once there's a new build I'll probably try again and this time do a much better job of catching the pd information. (I have the same situation in sw I debug too with info not provided!). At the time I was trying the new pegasus scheduler so that may have been a factor. but will try again ...
[Galaxy S II Original Android Development] aceofclubs:
Is the last_kmsg file only created when you use the long press on the power button to reboot when you have a lockup?

Just had a lockup using rc1. Was on charge while I was using it to browse. LP3 firmware. Used the long press of power button to reboot but no last_kmsg in /proc so sorry gok I can't help with this one.

I did have a little problem over night. As you can see from the screenshots my battery was going downhill fast, without any noticeable wakelocks. I double-checked with bbs and from the timing the suspend_backoff kernel wakelock seems to be the culprit. I tried searching for it but didn't find anything. Maybe I'm just missing my first cup of coffee :rolleyes:

Does anybody knows where this comes from? I'm curious because apart from this, standby drain seems to be even better than from my GB times (or maybe the long time on not optimized CM9 kernel was that hard on me ;) ).
