Siyah Gingerbread kernel (v2.x)

[Shotgun84]

You'll notice the difference while loading webpages as its a case of blink and you miss it. Overclocking to 1.6ghz does use a little more battery but not that much more. I used performance governor for the benchmark which isn't supposed to be for everyday use as it drains the battery. I think its more for using when your phone on charge. But still overclocking and using a sensible governor will still make your phone feel a bit speedier.

What we need now is some idiot to test it!

You called?

9h 32m so far and battery is at 84%. No wakelock issues, lag or other problems noticed. This with Dlev 3.1, smartassV2 governor, standard clocks but my own tested undervolting settings.

 

[Shotgun84]

I've had to go back to dark knight. There's been a couple of times today where I've been using my phone and the screens gone black. The only way I could get it working again was to boot into recovery and then reboot from there.

 

[Rudedawg]

The only anomalies i've encountered was when trying to call someone it went silent yet the person i called could hear me. Also when they called me I couldnt hear them. This was however a one off but strange none the less.
That an the battery is pants lol . I may buy one of those bolt on batteries anyway.

Are you undervolting the CPU at all? Mine won't resume from sleep if I use 100MHz @ 800mV. 825mV is the minimum I can use, which is annoying as both 200MHz and 500MHz are 100% stable at 800mv.

 

[Shotgun84]

Nah I wasn't undervolting, I didn't even overclock. The only thing I had changed was the governor to SavagedZen.

The TV show, "Top Gear" has, "The Stig"... we've got..... "The Slug".

Siyah 2.1.1 (anti-lag update) out now!

Changelog:

UI lag and browser lag is fixed. no changes in the source code.


Certainly liking the Siyah over the Dark Knight kernel.

No lag

Good battery life

smartassv2. 200 - 1200 No profiles Stock voltage

Will give this a go today.

sounds promising, and may try again

but have recently switched to speedmod - although it doesn't have all the governers, bln, oc/uv support, and all the other bells and whistles of siyah, it seems to get rave reviews on xda, so been trying this the last couple days
the speed is simply awesome, my s2 has never been so quick
and battery drain is a flat horizontal line when not in use
scores 6200 on antutu
definately no lag with this

even though i cant mess around with governers, the speed and battery are so good i think i'll stick with this for a bit.... certainly a kernel that lives up to it;s name.

 

[Hawker]

Put 2.1.1 on Dlev3.1
WOW! VERY impressed so far. Extremely smooth. Not a lag in sight for me. Browsing also seems extremely snappy.

Comes with CWM v5.0.2.7 which has the old-style orange text instead of cyan. Also has back-key soft button support as per v4.

Going to resotre my CheckROM backup and put it on this too to see how the two compare.......

Well CWM4 backups restore fine on CWM5.
I can also confirm CWM5 backups are NOT compatible with CWM4

Installed Siyah 2.1.1 on ChekROM and as with DlevROM, early signs seem very good indeed. I will keep you posted......

Not sure if its the ROM or kernel, but is anyone on Siyah 2.1.1 and has BLN working?
I cant get it to work on DlevROM 3.1 (even though this is reported as fixed in this version)
I'm putting CheckROM back on for now to test. If it works, I might try applying CheckROM's BLN mod over DlevROM......

Yup. BLN works on CheckROM with Siyah 2.1.1
I will now try applying CheckROM's BLN mod over DlevROM to see what happens.....

BLN NOW WORKS by doing the above.

Siyah kernel 2.2beta1 is up.

v2.2beta1 changelog:

init.rc changes to support ICS based ROMs (not yet finalized)
xz compression support. better compression with faster decompression (boot). not as fast as gzip in decompression but size matters more for me.
initramfs fixes to get rmmod working (thanks to smitna)
blue color in CWM recovery 5.0.2.7, again with back button support
reverted some files and the speed is better now. I don

 

[Slug]

Okay, my sense of duty says I have to test this out. Backing up now.....

Some say that he is more machine than man... we just know him as, The Slug!

Early results are favourable for me.

(actually, with my track record on kernels, this should be the kiss of death for this one!)

 

[Slug]

Some say that he is more machine than man

Aye, a very badly-oiled and creaky one this morning.

Early results are favourable for me.

No issues found here so far, either. It's certainly stable - I managed a 7437 in AnTuTu last night @ 1600MHz - and since coming off the charger this morning battery usage has been 1%/hr.

 

[Rudedawg]

yeah oddly I got 7437 on DK this morning. Highest Ive had yet.
Battery is about 10% over night. Was worse on Siyah 2.1 final. Meh I dont get how people only lose 1% in a night of no usage. :S 4 hours is about 50% for me

 

[Sydney99]

That's high battery drain.you used better battery stats and checked your wavelocks?

 

[Rudedawg]

Cant say i have. will check now.

That app doesnt exist on the market in uk so downloaded Juice defender

 

[Sydney99]

Have pm'd you a link to better battery stats on xda.

 

[Rudedawg]

Have pm'd you a link to better battery stats on xda.

Cheers mate. I found a copy of the apk in a dusty folder in my hdd. If its not right ill go with your link.

Siyah 2.2 beta 2 is up!

"some patches applied: posix-timers: RCU convention [Eric Dumazet], Fixed ext4 disk write performance regression
default i/o scheduler set to cfq (some of my friends think it is working better with 1080p recording and it is set as default by the stock kernel). I am still using sio FYI.
kernel config changes
reverted all changes in arm platform sources
removed all unsafe optimization flags
disabled tvout. I will convert it to module later"

Here I go again!

UPDATE

Both 2.2b1 and b2 seem very smooth on 100MHz. More so than 2.1.1.

 

[ironass]

Siyah 2.2 beta3 is up!

"Changes:

bootloop and cache rebuild problems are fixed. it was related with bootclasspath (to support ICS)
"

Here I go again!

 

[Slug]

You can be chief guinea-pig for this one, pal. I'm still getting over the fact that beta1 spent most of today out of wifi and 3G range without trashing my battery. It's the politest kernel I've used.

If beta3 is as good as beta1 has been to me today... I'll be a happy bunny!

 

[Shotgun84]

I have that feeling I'm going to struggle to keep up. Beta 4 is available.

 

[Hawker]

I'm on 2.2 Beta4 with no problems, with Beta5 is now starting to trundle out.
