Siyah Gingerbread kernel (v2.x)

Dark knight seems every bit as good as siyah. It didn't seem as smooth as siyah at first but I've changed my governor and scheduler and its hard to tell them apart. Speed is about the same so I think its just going to come down to battery. Which its holding out nicely stu the moment.

I'm glad I got in early before sydney had the time to break it.
 
I've never been so happy to be annoyed. I was just settling in with DarkKnight and now I have to give siyah placebo a try.
 
There's no lag on either dark knight or siyah 2.5.2b. Siyah loads webpages quicker and gives you the option to change voltages so it gets my vote at the moment. Will have to wait and see how the battery performs.
 
I had DK 2.5.2p on for what had to be all of 4 hours and found that to be very good, but I'm just a flashing whore, so now giving Siyah 2.5.2 (no GT reference for this one I notice) a go.

First signs for me are that there are no great differences in usage. Homescreens and app drawer are both ridiculously smooth on both.
Browsing I find pretty much identical
only difference I could find was in boot up time (on SECOND boot) from initial GT-I9100 screen to when the phone has truly settled (ie. no more media scanning notifications etc. On Siyah this took 45 seconds On DK 2.5.2 this took 50 seconds.
So absolutely nothing in it.
I will keep siyah on to test battery drain tonight, and may compare it with DK in a few days time

Hell yeah! Another excuse to delay Xmas shopping. :)

I'm not sure about this one. May sit it out and see what you guys have to say. :rolleyes:

I've just put it on so no real impressions yet, other than scrolling the apps drawer and home screens seems as smooth as v2.5.1. I looked at the voltage settings and they're very conservative, between 100mV and 50mV above the settings I usually use. I'll leave it idle for an hour or so and then check that it's deep-sleeping as well as previous versions.
 
I cant notice too much difference at all between Siyah 2.5.2b and DK 2.5.2p in terms of smoothness and overall performance.

I'll be reverting back to DK for tonight as it is supposed to be more battery friendly than Siyah to see how battery drain fares tonight....

Which governor are you using Slug?
 
I'm glad you asked the question Twinn. I've been trying to play gta3 today and it kept freezing and sticking me back in the app draw. Reminded me I was using deadline which is rubbish under a high workload. Stuck my scheduler on cfq and its as smooth as anything.
 
Here's the link to the siyah xda page
[KERNEL] SiyahKernel v2.5.1-GT - "One kernel to rule them all" (SAMMY&AOSP ROMs) - xda-developers

I'm sure it will be completely irrelevant by the time someone reads it but it doesn't show up on any google search at the moment. I had to rack my brain and remembered hawkers "is anyone here using this kernel" thread to get the link. I'm sure its somewhere in every siyah thread but if your anything like me (which I hope you're not) you can't be assed to look through every page. Lucky I'm a sort of rain man for pointless crap. Just never ask me to remember anything important.

I wonder if that's related to a HD video playback issue that was reported? The d/l has apparently been refreshed to include a fix for this.

I have to ask. Where's the fix? I spent along time trying to find the siyah page and by the time I did I forgot why I was there. Hence the random bull a couple up.

Totally agreed Kie its spot on. The challenge goes out to gokhanmoral, can you make it better?
 
Siyah v2.5.2 is up! :)


"If you have problems with v2.5.2b, use this version. If not, don’t.


Changelog:

same features as in v2.5.2b but with the following exceptions:
no default undervolting. all voltages & clock values are the same as stock
SLAB (SLUB in 2.5.2b)
disabled CONFIG_RCU_FAST_NO_HZ
android logger is enabled (in v2.5.2b, you have to flash EnableLogger.zip to enable it)
dynamic bus frequency mode (in v2.5.2b it is static)"


(Not to be confused with Siyah v2.5.2b (placebo-edition)... but it will be!) :D

Don't say that to me. I've had no problems but I'm a whore for flashing. I think I'm going to have to bite my lip this time.:D

If 2.5.2b is working for you... then don't!

Unfortunately, like yourself and some others, I'm a flashing whore too.

Initially when 2.5.2b was released, I decided against installing it because I was getting amazing results for battery life and performance, with my usage, from 2.5.1 with some settings tweaks.

However, after reading the posts here, I decided to download and install the 2.5.2b (placebo-edition) with video fix. I reset both SetCPU and Voltage Control and used the Ultimate Kernel Cleaning Script before install.

Once installed, I began to encounter all sorts of problems. On reboot I got a totally black screen with just a notification bar. Video's would not play or record. Sleep of Death, etc: Basically it did not like me. I did various wipes. Remounted SD card. Flashed a previous backup. Re-downloaded 2.5.2b and re-installed. I was loathe to tinker too much with this already heavily tweaked version as it only seemed to make matters worse. Over 3 hours, you name it, I did it!

In the end I accepted the fact that 2.5.2b just didn't like me!

I did notice however, that most of gokhanmoral's settings for voltage, etc, were roughly the same as the one's I'd been using on 2.5.1 so I just re-installed that again and applied some tweaks and everything was hunky dory.

I've now just downloaded and installed 2.5.2 which is working fine on my phone and, to all intents and purpose, is no different from 2.5.1.

I'm now about to apply some tweaks and see what happens. :eek:
 
Show us your tweaks! :D

2.5.2b seemed fine for me. I didn't get chance to test it's battery overnight as I had DK on last night and this seems very good for me. Lost 3% in 8 hours overnight with no sinister wakelocks and 85% deep sleep.
Not sure whether or not to stick or twist! :rolleyes:
