****SIYAH KERNEL DEVELOPMEMT... STILL GOING STRONG!!!****

Thanks to his loyal fans and and appreciative SGS2 community Siyah is still going strong on the SGS2. GM has a donated device to play with and with recently released official JB sources development has resumed in earnest...
================================



If you have been directed here after posting in the original Siyah thread and are wondering why. Or you are a bit unsure which thread to post to, the man himself posted this:

I always welcome your feedback such as "it was working in X version but it is not working Y, it gives me blahblah problem and here is the logcat and last_kmsg output".
sometimes last_kmsg cannot help but it is always good to post it if you are unsure.
normally, I have patience for those who has no technical knowledge. but lately there were too much talk in the development thread which was only wasting people's time reading it.
you can post your screenshots and talk about "best settings" here.
but they do not help much with the development.
I will read this thread.
but not as much as I read the other one.

So there you have it, honestly rank your noobishness to yourself and familiarity with Siyah and follow XDA general rule no.1: READ the last 10 pages of thread before posting and skim the rest. Once you are a familiar with Siyah don't be scared to post intelligent suggestions and such on his thread. You will find he is one of the most helpful DEV's around especially for the inexperienced... he won't even call you a Noob

===============================

There is already a dual use cm9/siyah combination use thread for disvussion so use it. For general discussion about your Siyah experience and/or issues please use this thread.

================================

***If you consider yourself a inexperienced post your questions here first.***

Since Siyah is the all-in-kernel there are simply too many different roms that it can run making it very hard for the dev to troubleshoot if every little issue is posted on his dev thread, many of which are super noob, noobish or posted without prior testing/problem solving/research.

- battery issues
- wake locks
- PERCEIVED Bugs. Remember that what you experience as a bug is likely just a rom issue or settings related. If many users experience the same thing then GM will take a look.
- extweaks issues
- CPU related
- suggestions/additions to future kernel versions.

================================

Remember this thread is for EVERYTHING related to general Siyah kernel experiences you have and issues.

Welcome back GM

***Current affairs! Latest release feedback and tidbits***

***New Pegasus governor***

***Relevant contributions from guys who know stuff.

Most old hotplug configurables (which are now useless in ExTweaks when using this governor) can now be found in the governor. Use the new SetCPU for example to be able to configure everything.

SetCPU is currently the only GUI interface usable to tweak Peg... for the curious

The lower frequencies not being used is a quirk of pegasus and I pointed it out to Gokhan and he will make it configurable, see the dev thread for info. Nothing you can do about it right now as that nonsense is hardcoded into the governor for now.

And this from GM about the quirky frequency scaling. I'm a bit unsure about his reference to 100mhz not being a good idea as it seems to behave normally for me set as min.

load will be high on those frequencies and it will jump to a higher freq very quickly.
I have added a small workaround to prevent that but I think it is not enough.

*** My Observations so far:

- Scaling misses 200,300 mhz steps completely. Others are barely touched.

- multi core aware. Probably not the same version that will release with the SGS3.

- don't bother with the hotplug settings in extweaks they WILL BE NON-FUNCTIONAL when using Peg.

- setting 200mhz min freq will actually set 500mhz. Setting 100mhz min will work and will jump straight to 500.

scaling issues much improved in 3.2.5 so above info mostly no longer relevant. The new Hot plug governor appears to be be very similar to Pegaasusq. Will add info as it's reported

Now I have set both programs to identical settings (governor smartassV2), but I think this is it unnecessary...

Thanks Neo

extweaks has it's own set parameters which are configurable (the ones provided by gokhan). whatever other settings you want to change (for example voltages and freq's, governor's) you'll have to do with other mechanisms, such as built-in ROM control of your prefered rom, or voltage control app, nstools, setcpu, or any other app like those.
Try some of them and see what suits you best.
Extweaks is only for the kernel specific tweaks, but essential if you want to tweak those too....

Yes but it has died. I will endeavour to update the OP regularly with this fresh start.

i have been using siyah kernel 3.2.1 and am experiencing massive battery drains?? i dont know what settings to use. can someone share with me settings for good battery backup and optimum performance. I have deleted some apps that were causing wakeups but still im attaching my bbs dump for people to see and comment. Please see the dump and suggest all i should do.. ive deleted the fb app, turned off latitude and deleted some other weidgets like BMW , beautiful widgets..

Kindly share your settings in detail..

**The so called "Slow-motion" bug**

Possible solution to the slow-motion bug???

Un-check Force gpu rendering in developer options. That will eliminate most slow motion bugs. I haven't experienced any bugs after that, but you might.
:what:

Post your results for others benefit......

Stock LPQ 3.2.3

Learn to read the BBS dump on you own, don't wait for someone to do it for you, you clearly did not look at your own dump report.

These things are fairly obvious e.g

multipdp (): 1 h 30 m 53 s  (5453 s) Cnt:(c/wc/ec)579/0/578 9.4%
secril_fd-interface (): 1 h 58 s  (3658 s) Cnt:(c/wc/ec)1178/0/0 6.3%
com.google.android.apps.maps (): Wakeups: 966
ccc71.bmw.pro (): Wakeups: 961

I looked at your dump for 5 seconds and saw those, do those figures seem normal to you?

Don't just remove widgets, reconfigure the app or uninstall them, some apps are so poorly written, they perform the same even if there isn't any active widgets
