My aim is to make kind of minimalistic, debloated kernel which will be perfect for daily usage and it will be speed demon whenever you would like to play some games
Please respect my time spend on doing that kernel and read at least those few opening posts

You probably would like to have the best kernel possible so please left here TONS of feedback and opinions, suggestions, etc

I won't write that my kernel is super and the fastest and that every feature/update give +50% performance, it is stupid attitude.


FEATURES:
*BFS (brain**** scheduler) - doesn't give too much cpu boost but make performance more stable
*fsync disabled
*o3 and ofast optimiaztion - I will stick to classy,old,good toolchains, I won't use LINARO ones because I don't see any point in doing so
*removed slowdown in downloading files when device is locked
*forced fast AC charging (device charges faster via USB)
*only available iosched is SIO
*440mb of ram - I won't fight for every mb 440 or 445 doesn't really make big difference and it is huge value already, but I will try to expand it in future
*20% UV for LCD
*changed readahead for optimal sd performance
*LOAD_FREQ (4*HZ+61) avoids loadavg Moire
*nonblocking for entropy tweaks and some entropy changes
*debugging diabled (gpu too)
*frandom

FREQUENCIES (cpu,gpu,voltage)
1520mhz - 253,3mhz - 1375000mV
1320mhz - 220mhz - 1300000mV
1096mhz - 219,2mhz - 1200000mV
800mhz - 200mhz - 1075000mV
400mhz - 200mhz - 1000000mV

TO DO:
*rework voltages, they suck as for now
*rework cpu frequencies - I don;t like removing 200mhz but was needed to fix SODs
*rework lowmemory killer and ram management
*find and add good scheduler or tweak on of existing ones and delete rest of them
*add BLN (backlight notification)
*tweak touchscreen - I have to find optiomal values
*other stuff



I now there are many things to do yet, but kernel is really fine to use for now. I have limited time because I have my finals ATM. cheeres and peace


There is a problem with uploading... so I will post it here for a while:

FAQ

Q: How to install it?
A:Simply apply via CWM

Q: What does not work?
A:You tell me, should be exact as "stock" cm10.1 JackpotClavin's kernel

Q: What is O3 optimization?
A:

What is it with people and NOT READING? I believe the OP states that download links will come later. In other words not available now! Read, people! Read!

Yup I can't understand it too
If you really want to flash something please read the opening post.
I hope I will post kernels today.
But nice enthusiasm though

Short answer/opinion:

Voltages should be higher to support more unlucky devices (like mine), we can undervolt next; overvolting kernel default values instead of UV to reach stability is not safe imho.

Frequencies like: 200, 400, 800, 1200, 1500, aren't good? GPU, asaik should be: 200, 200, 200, 220, 250, no float.

And about SoD (maybe can help): I'm currenty using untouched jackpot's kernel with range 100~1200 (stock voltages); SoD appear rarely, but not "real SoD", if I push some hw button for some seconds the device turns alive. I experienced real SoDs immediately after undervolt all the freqs. This make me think that is not a low frequency problem.

Where did you cherry pick BFS from? I haven't been able to find the 3.0.X patch for BFS so I've never added it

I changed voltages a little bit, will uptade soon in OP
I will rework frequencies sometime but I don't think 800-1200 is good idea
no, I know what is the reason for SOD, partially

Overclocking on sultan kernel always causes my device to reboot randomly or sod.
Any chance of this being different with your kernel?
