[MIUI/CM KERNEL] SwiftExtreme-20112011 - FINAL

Hi all, welcome to SwiftExtreme MIUI/CM kernel
Kernel-20112011 - FINAL
Features :
-[20112011] Add autogroup to increase interactivity when screen on
-[20112011] Add autogroup to background process, it will reduce background process trying to get cpu attention by grouping process tasks, slightly increase battery lifetime
-[20112011] Update kernel to 2.6.32.48, more bug fixing
-[20112011] Reduce backlight voltage need, slightly increase battery lifetime
-[20112011] Introduce Powersaving version, the different is, powersaving doesn't have spare frequency at screen off, based on my testing, it increase lifetime around 10-20%, but gives you more delay when switching screen state
-[20112011] Introduce ability to turn off second core at specific frequency, slightly increase battery lifetime, read this http://xdaforums.com/showpost.php?p=19419710&postcount=334
-[13112011] Reduce cpu voltage a little bit
-[20112011] Add voltage in some area to increase stability
-[13112011] Increase second core turn on frequency limit threshold and delay second core turn on, faster second core turn off. It should increase your battery lifetime when doing light task, like reading facebook, scrolling homescreen/drawer, watching movies, etc
-[12112011] Enable EXT2 and LED fix problem
-[12112011] DDR Undervolt
-[12112011] Return back to 216Mhz as lowest stock, introduce +100Mhz as spare frequency to make kernel can breath a little when doing task at screen off. It should make your screen turn on much faster and reduce MP3 glitch. With this method, kernel will work at 216Mhz-316Mhz at screen off
-[12112011] Add Simpe I/O as kernel default scheduler, watch out for tweakpack, it may change kernel scheduler on one its script
-[12112011] Now compiled with gcc 4.6 with -Ofast option
-[12112011] Implement some patch that fix memory leak, optimize lowmemorykiller function, and mmc sleep mode
-[05112011A] Now compatible in nightly CM and MIUI begins from 1.11.4 version
-[05112011A] reduce some volt in lowest clock and sdram
-[05112011A] use git SHA-1, it should speedup kernel boot process upto 11%
-[05112011A] Improve memcpy and memmove kernel performance
-[05112011A] CRC32 algorithm optimization. it should increase any activities that use CRC32 algoritm
-[05112011] Replace deadline with noop as kernel I/O scheduler
-[05112011] Compiler cflags optimization, use O3 right now....
-[05112011] Increase standby frequency clock to 256Mhz instead 216Mhz, slightly increase screen/phone call wakeup, battery drain itself doesn't change too much, still around 20% in 7 hours 3G, all sync ON in my area while standby.
-[05112011] cgroup speedup
-[05112011] Introduce file sync disabled, it boost kernel write algoritm with slightly increase rate data corrupt when your phone get crash(use androbench to bench the write speedup, bench first before flash the kernel to see the different). beside write access speedup, it make MIUI more smooth, faster installing apks, and in some games it seems the loading much faster
-[05112011] Increase TCP initial congestion window to 10 and initial receive window
-[05112011] Remove Jhash3, replace with Jhash speed tweak
-Provide 1.5Ghz and 1.2Ghz version(use PimpmyCPU to control clock and voltage)
-Excellent standby power management(Make sure you remove any script that control screen state ON/OFF when using this kernel, it will mess the kernel mechanism)
-[30102011]JHASH 3.0 patch
-SLQB as default allocator
-[30102011]Deadline I/O Kernel patch NAND storage optimize
-Improve scheduler latency
-Voodoo V1 sound driver

Thanks for muffindrg that provide benchmark score Quadrant and Antutu...


Tips increasing battery life :
1. Build your rom installation with Toogle2G, it helps a lot battery drain when screen off. 3G only active while screen ON, and get turn off automatically back to 2G when screen OFF.
2. Pick correct baseband, better signal, more battery life
3. When you're using script in init.d, just make sure you don't have lot of scripts that do looping on background. eventhough it only takes small amount resources


fire3d got it running on stock, based on his testing, brightness not working on stock, check it:

nice work mate!

can you tell me what the benefits are when you compare it with VorkKernel?

I can't promise anything, the only thing that I can tell, you'll get Excelent Standby Time...

owain94 said:

then im gonna flash it right now
do i need to remove my setCPU screen off profile?

Click to expand...

Click to collapse

Yes.., it will mess the kernel screen off handling

deadmetal said:

I take it that this should also work with cm7?

Click to expand...

Click to collapse

I think it will work with cm7 rc1, because MIUI use that as base.

Thanks for your job

But i have BSOD after a call with SwiftExtreme HOC-30102011
on MIUI 1.10.28

Click to expand...

Click to collapse

I'm already test it for 3 days, got no problem receiving call, there is a probability that your phone doesn't support low clock when in call... If your phone doesn't support it.., SwiftExtreme is not for you .

maybe on next version, gonna make SetCPU compatible, so it can make "on call" frequency control..

cheers

When you're in call, screen off. When screen off, kernel down clock mechanism get triggered. So, your phone probably not support low clock when in call. This kernel down clock when screen off is the most important feature of this kernel.
