[KERNEL][14APR-K13E]Insane OC/UV kernel
- Thread starter xan
- Start date
Thanks for valuable feedback.
Its always good to look behind and reevaluate some statements.
I wont be doing this much, I dont want to break it.
The smoothness can be related to so many things... like kernel tick hz, preempt, scheduler, clock changes, maybe even compiler used.
My main aim will be to leave the hard work to hardcore and focus on oc changes, however there will be no new features to oc code. It just needs to be stable, change states accordingly.
I wont add 600 and 900 Mhz.
I wont let it clock over 1280Mhz
Those are design principles.
Hi Xan
I am new to OC and I am messed up with those setting in Voltage Control.
Would you mind telling how to set up those figures in the app?
It will be great if this can save more battery while increasing the performance than speedmod

Yes, drivers dont load with preemptible kernel
Its volountary preemptive desktop.
It does nothing? I had no idea, you got me here.
Thats very individual. Most cpu's (80%) should be able to handle 1120 mhz and 99% should handle -25 on lower (100-800).
Mine isnt best but can handle 1200 and -50 on 100-400 and -25 on 800. Thats very stable and safe for me, probably if I spend enough time I can find a bit higher values.
Mine is stable too with some UV on lower fq, -75 on 100MHz, -50 on 200-800 and -25 on 1GHz . However i can't OC to 1280MHz, it's unstable on all OC kernels i've used so far. 1.2GHz works fine.
With setcpu mine is stable at 1280, but i will try to use uv to vet more battery life....

Quadrant is a bad benchmark software for sgs,try smartbench instead

Cheers worked it out in the end, still had v3 alpha installed as a system app... (ticked in rom kitchen)
For anyone else with the same problem just use titanium backup to uninstall the old version and install the new one again..

22This is an alpha release!
It is nowhere as stable and tested as Speedmod itself!
What it is?
All I did was to compile Speedmod (To be honest, I'm clueless what gizmos are sitting there, but its great)
Credit should go to hardcore. He is author of this kernel, I'm responsible for breaking it and making bugs.
What did you break?
+ OC/UV features (this might fry your device)
+ some clock changes to keep it stick more to 100mhz (should be at least)
+ preemptive config (needs testing)
* optimised for size (not sure if this is good)
* noop is being the default scheduler (i just like it)
* 341MB ram (if someone is curious about this)
- everything I have broken along the way (maybe nothing)
So (as you can see) its pretty alpha
How do I?
Just flash the CWM package.
This kernel is being tested onInsanity ROM
, which I personally use.
If you want some more power, extras like nitrality (Ha I bet you dont know what it is!) I recommend you flashing this one.
By default no OC is applied. You need to download and use Voltage Control.
BE SURE TO USE LATEST (3.0.1)Voltage Control app!
Voltage Control in Adroid Market:
Wooah, I think its stable...
You can never be sure.
My device freezes just after going into menu in Asphalt 5 (Samsung apps), so thats the test I can recommend.
I suggest you do the following:
OC 1120Mhz -> 1x Asphalt race,
OC 1200Mhz -> 1x Asphalt race,
OC 1280Mhz -> 1x Asphalt race.
If that is stable.. Well you can be 99% sure, but you know, 1% off one week is ****loads of time ;p
Why?
Because I can
Consider this a tribute to all developers who constantly work on improving Galaxy S kernels!
Then tell me who was that?
- hardcore - its his source
- sztupy - excellent recovery
- supercurio - sound fixes, lagfix ideas
- raspdeep, unhelpful, laststufo, trasig -> oc code
- all others involved, sorry if I missed anyone! (its late)
- personal thanks to nitr8 - support and testing, some recovery tweaks (more coming, if hardcore releases sources for recovery)
So what you gonna do?
Basically wait for feedback. As always it will be mixed.
I dont have many plans for this kernel, I will just upgrade with every new Speedmod (well, if time will allow).
However, I dont want to release kernel more than once a week.
Erm, sources, bit#^?
See: insane.7z (fixed)
Its code prior cleaning, some leftovers are there.
Lots of debug info, to track whats going on (kmsg is disabled in release, so they dont work anyway)
F...udge! I'm stuck at bootlogo!
Flash back your previous kernel and disable lagfix from recovery!
F...udge! My device is totally unstable
Check it after few mins of runnning. If it goes over desired frequency -> report here with outputCode:cat /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state21
Did you have a lagfix on as K13c only reads rfs and EXT4 ?? I flashed over DamianGTO and it was fine, but I disabled lagfix first1Well if you choose max freq 1120 then have 1120 frequency enabled in advanced screen (assuming you use Voltage Control 4) then something is wrong with kernel.
At this moment kernel its provided 'as is', without any support, its simply outdated.
I made some tests with Insane GB kernel, however ATM I'm running CM7 and awesome TK-Glitch, so I'm in no need of working on kernel for stock-based ROMs.
