Thank you smartgardens, Byrana & Puzzlegirl for u kind donations

• i will be creating 3 series for the kernels (this is only for v02 & below)
  • S-series - Stock like - will be using stock SE kernel voltages, so should work on most devices w/o issues
  • X-series - eXtreme - will be undervolted, so as to give better battery life (has been discontinued from V03 since user-level CPU voltage control has been added to kernel)
  • FS-series - FailSafe - will be using stock SE kernel voltages & stock frequencies (no under/over clock) [245-998Mhz], so should work on ALL devices
• i have unlocked frequencies from 128Mhz to 1228Mhz (many intermediate frequencies)!!!
• thats why calling it "Power to The People" so u decide which voltages/frequencies u want
• X & S series kernels would be having all those frequencies unlocked!
• now for sake of safe booting i have hardcoded the startup/bootup frequencies to min:245, max:998 (in ramdisk) u can over-ride that using setcpu, ('set at boot' option should be used only after u have done adequate testing)
• i want u guys to please test these kernels for a few hours (10-15 hrs atleast) on the ROM of ur choice!
• i would recommend that u DO NOT use high frequencies for long time! this may damage ur device!
  [*]the high frequencies are just for temporary boost/benchmarks/showoff
  [*]you have been warned!

1. Rooted ROM based on latest SE FW 3.0.1.G.0.75
2. working Recovery

1. Stock Rooted SE FW 3.0.1.G.0.75
2. CM7-ZMOD v003
3. FreeXperia Project CM7 - FXP018
4. WB's ROM v4.0.4
5. TripNMiUI ROM

• see each cpu/chip is different
• each is unique and has different tolerances
• so dont directly jump to max frequency/undervolted kernel (X-series)
• slowly keep increasing the frequency
• check its stability for 5-10 hrs
• check for random reboots
• check which one is best suitable for ur device
• if u start getting reboots/wlods then throttle back and use lower frequencies
• if X-series kernels give u random reboots/instability then use S-series kernels
• remember just because someone elses device was able to work at that frequency/voltage doesnt mean that ur phone can support/handle that frequency/voltage

• derived from FreeXperia Kernel:
  • kernel version 2.6.29
    
  • latest SE sources patched
    
  • Classic RCU
    
  • added an interesting change in GPU frequency *might* increase gaming/benchmarking performance
    
  • FPSuncap at kernel level
    
  • removed nv_vsync and set to manual
• my additions:
  • user-level/runtime CPU voltage control [VDD control "sysfs interface"] (for more info keep checking this post: http://xdaforums.com/showthread.php?p=16877711#post16877711)
    
    
  • changed in-call volume (i think its now improved)
    
    
  • added fixed ondemand & conservative CPU governors
    
    
  • z's workaround for added for cpu idling too high (http://xdaforums.com/showpost.php?p=16459282&postcount=111), thanks to Karlson2k for informing me about this!
    
    
  • VERY IMPORTANT FIX: device now doesnt touch high frequency while booting! this *might* solve the issue for most users...
    
    
  • enabled SWAP support
    
    
  • cpu voltage modulation:
    • FS & S-series kernels - stock voltages
    • X-series kernels - undervolted (has been discontinued from V03 since user-level CPU voltage control has been added to kernel)
  • optimized frequency-voltage table
    1. added 192 Mhz frequency and unlocked frequencies from 128Mhz to 1228Mhz [for both series]
    2. further decreased voltage (improved undervolt) for many frequencies [X-series only]
  • bumped jHash to v3
    
    
  • increased VM MAX READAHEAD to 512KB
    
    
  • updated config with iptables fix for droidwall & co (thanks to Jerpelea)
    
    
  • startup/bootup frequencies set at min:245Mhz, max:998Mhz (in ramdisk)
    
    
  • init.d scripts execution support (/system/bin/sysinit will be called/executed via init.rc) [for more info check this]
    
    
  • bash shell included in ramdisk (located in /sbin/bash) [i recommend using Hacker's KeyBoard to take full advantage of bash shell features]
    
    
  • CPU Governors activated/added: (the inbuilt governors have not been disabled) [default: OnDemand]
    • Smartass [now using different sources][settings used from here, thanks to viulian for those settings/parameter values]
    • Interactive
    • Scary (for info on how it works read this)
    • MinMax
    • smartassV2 (thanks to erasmux) with some fixes from ThJap
    • interactiveX (thanks to imoseyon) with some fixes i made
    • SavagedZen
    • Lagfree (thanks to ThJap)
    • BazillianWax
    • Smoothass
  • compiled using GCC-4.6.2 with O4 optimization (thanks to tkymgr)
    
    
  • File System support (in kernel):
    • EXT3
    • EXT4
    • NTFS
    • SquashFS
    • NFS (server/client)
    • CIFS
  • enabled access to .config through /proc/config.gz
    
    
  • enabled ARM THUMBEE extensions
    
    
  • enabled NLS_UTF8 support
    
    
  • SLAB memory allocator
    
    
  • I/O scheduler added/activated: (the inbuilt I/O schedulers have not been disabled) [default: deadline]
    • Simple I/O
    • BFQ
    • CFQ (Tweaked)
    • Anticipatory
  • Tweaked scheduler params to give better responsiveness

• Scheduler parameter Tweaks ported from erasmux's Hero-Fly Kernel sources

• and finally ME for getting this all together for u guys

1. take backup of ur system before using this
2. download the kernel package u want and place in SDACRD
3. flash the kernel package via recovery then reboot into android OS
4. check Menu -> Settings -> About Phone -> Kernel Version to check if the kernel has changed or not

please test them out and let me know how it goes!

1. if u get stuck at bootanimation then try rebooting into recovery and wiping cache/dalvik-cache and then reboot
2. on v01-X (at 128Mhz) the voltage is very low (875mV) which may cause screen off reboots... if that happens then just switch to 192Mhz as lowest frequency...
3. if the X-series doesnt work for u then try S-series.... if S-series doesnt work for u then try FS-series...

• preconfigured init.d startup scripts for setting cpu voltages to S/X series values (for v04 & for v03)
• VERY Important SetCPU information (in second post, towards end)
• Information on cpu governors
• lots of info on CPU Governors and I/O Schedulers
• [DISCUSSION-TEST] CPU Governors and I/O Schedulers
• the new update to WB's ROM (4.0.4) has some issues... check the following: http://xdaforums.com/showpost.php?p=17049346&postcount=565

Hey doom ,
Is there a way u can add cwm recovery native to your kernel ?2

Is in-call volume hack in this kernel? I can not see it in first post

Hi,

Sorry for stupid question, i'm a newbie. Is it compatible with Wolf's Stock modified ROM??

Many thanks in advance

must be the unlucky one, just bootloops twice and freezes on xperia man. wiped dalvik cache.
