Insanity [ROM] by nitr8 powered by ULTIMATE SUPER OPTIMIZED Kernel !!!!

If you want to disable ramzswap put S_ramzswap_disable.sh from S_scripts.zip into you /etc/init.d directory

If you want to maximize ram performances put S_stock_mem_timings.sh from S_scripts.zip into you /etc/init.d directory

If you want to disable VSF put S_VSF_Disable.sh from S_scripts.zip into you /etc/init.d directory

The file "Customized_freqs.txt" contains a list of usable frequencies, and all of them divisors, for customize first four kernel frequencies.
If someone want ... i added possibility to donate something by paypal on my profile. If you appreciated my work you could give me a little gift.
It works on all stock froyo ROMS !!

Istructions:

- BlackLigthNotificaion updated to v2.3.1
- Fixed a bug with external SD Mount
- Since this release the first four frequencies are completely user configurable :
There are four new sysfs files with this structure ARMCLK,MDIV,PDIV,SDIV,DIVA2M,DIVHCLKM,DIVPCLKM,DIVG2D,DIVMFC,DIVG3D
- /sys/devices/system/cpu/cpu0/cpufreq/user_free_freq_values_table_L0 original values (1600,400,6,1,7,7,1,4,4,4)
- /sys/devices/system/cpu/cpu0/cpufreq/user_free_freq_values_table_L1 original values (1500,375,6,1,7,7,1,4,4,4)
- /sys/devices/system/cpu/cpu0/cpufreq/user_free_freq_values_table_L2 original values (1400,350,6,1,7,7,1,3,3,3)
- /sys/devices/system/cpu/cpu0/cpufreq/user_free_freq_values_table_L3 original values (1300,325,6,1,7,7,1,3,3,3)

ARMCLK is the final CPU freq(Mhz) and it is a calculated value so do not set it as you want. It's value have to be calculate as follow :
ARMCLK = MDIV X 24 / (PDIV × 2power(SDIV-1)

where, MDIV, PDIV, SDIV must meet the following conditions :
PDIV: 1 = PDIV = 63
MDIV: 64 = MDIV = 1023
SDIV: 1 = SDIV = 5
(25/ PDIV): 1MHz <= (24/ PDIV) <= 12MHz

Es. ARMCLK = 400 X 24 / (6 × 2power(1-1) = 1600(Mhz)

DIVHCLKM is the divisor for main system frequency.

HCLK_MSYS(main system frequency in Mhz) = ARMCLK / (DIVHCLKM + 1)
Es(1600). HCLK_MSYS = 1600 / (7 + 1) = 200(Mhz)
HCLK_MSYS must be <= 200 (Mhz)

DIVPCLKM is the divisor for perimetral devices frequency.

PCLK_MSYS(perimetral devices frequency in Mhz) = HCLK_MSYS / (DIVPCLKM + 1)
Es(1600). PCLK_MSYS = 200 / (1 + 1) = 100(Mhz)
PCLK_MSYS must be <= 100 (Mhz)

DIVA2M is the divisor for 2d and 3d subsystem frequency.

SCLKA2M( 2d and 3d subsystem frequency in Mhz) = ARMCLK / (DIVA2M + 1)
Es(1600). SCLKA2M = 1600 / (7 + 1) = 200(Mhz)
SCLKA2M must be <= 400 (Mhz)

DIVG2D is the divisor for 2d graphic subsystem.
DIVG3D is the divisor for 3d graphic subsystem.
DIVMFC is the divisor for Multi-Format Codec.

these values must be calculate as follow :

SCLKG2D= SCLKA2M / (DIVG2D + 1)
SCLKG3D= SCLKA2M / (DIVG3D + 1)
SCLKMFC= SCLKA2M / (DIVMFC + 1)

Es(1600).

SCLKG2D(Mhz)= 200 / (4 + 1) = 40(Mhz)
SCLKG3D(Mhz)= 200 / (4 + 1) = 40(Mhz)
SCLKMFC(Mhz)= 200 / (4 + 1) = 40(Mhz)

Just to try by your self the values for 1200 and 1000 are (1200,300,6,1,6,6,1,3,3,3) and (1000,250,6,1,4,4,1,3,3,3).
To set your values at start-up crete a S_xxxxxx.sh script file as follow :
#!/system/bin/sh

echo "1600 400 6 1 7 7 1 4 4 4" > /sys/devices/system/cpu/cpu0/cpufreq/user_free_freq_values_table_L0
echo "1500 375 6 1 7 7 1 4 4 4" > /sys/devices/system/cpu/cpu0/cpufreq/user_free_freq_values_table_L1
echo "1400 350 6 1 7 7 1 3 3 3" > /sys/devices/system/cpu/cpu0/cpufreq/user_free_freq_values_table_L2
echo "1300 325 6 1 7 7 1 3 3 3" > /sys/devices/system/cpu/cpu0/cpufreq/user_free_freq_values_table_L3
​

Well done, this is faster - 20% boost in Quadrant score, can't feel much real world but the increase is there.

I downloaded this kernel. But odin does NOT detect the file as a .tar.. The filename has with it the .tar extension, but my pc detects it as a .zip file. what do i do?

edit: LOL nevermind. i just forgot that i hid the extensions so i shifted to displaying the extensions and edit it from zip to tar. :p

This thing works. I have Tayutama's superslim version of JP6 with AOSP, and it works just faster. :D Trying to install more apps and see how it does. Great stuff!

Do optimizations have any affect on battery life etc?

Hmmmm... I'm no pro.. But I think faster performance means more effort on the hardware, which means more energy will be used. I THINK. :p

By the way, I have just downloaded another ROM, and when i tried to go to recovery, my screen hangs at the galaxy screen. :p Went back to download mode, and I'm flashing a different ROM at the moment.

Anyway, tried using linpack and quadrant. Numbers weren't significant, but response in real time is a better benchmark than these programs. It feels snappier and faster. :)

Would like to try, but as a captivate user, I don''t like i9000 roms without reorient kernel to keep my buttons properly mapped, my power button in recovery, autorotation and the other things that kernel addresses......

    If you want to disable ramzswap put S_ramzswap_disable.sh from S_scripts.zip into you /etc/init.d directory

    If you want to maximize ram performances put S_stock_mem_timings.sh from S_scripts.zip into you /etc/init.d directory

    If you want to disable VSF put S_VSF_Disable.sh from S_scripts.zip into you /etc/init.d directory

    The file "Customized_freqs.txt" contains a list of usable frequencies, and all of them divisors, for customize first four kernel frequencies.
    If someone want ... i added possibility to donate something by paypal on my profile. If you appreciated my work you could give me a little gift.
    It works on all stock froyo ROMS !!

    Istructions:

    - JPX Kernel Aligned
    - Minor memory tweaks.
    - BlackLigthNotificaion updated to v2.3.1
    - Fixed a bug with external SD Mount
    - Since this release the first four frequencies are completely user configurable :
    There are four new sysfs files with this structure ARMCLK,MDIV,PDIV,SDIV,DIVA2M,DIVHCLKM,DIVPCLKM,DIVG2D,DIVMFC,DIVG3D
    - /sys/devices/system/cpu/cpu0/cpufreq/user_free_freq_values_table_L0 original values (1600,400,6,1,7,7,1,4,4,4)
    - /sys/devices/system/cpu/cpu0/cpufreq/user_free_freq_values_table_L1 original values (1500,375,6,1,7,7,1,4,4,4)
    - /sys/devices/system/cpu/cpu0/cpufreq/user_free_freq_values_table_L2 original values (1400,350,6,1,7,7,1,3,3,3)
    - /sys/devices/system/cpu/cpu0/cpufreq/user_free_freq_values_table_L3 original values (1300,325,6,1,7,7,1,3,3,3)

    ARMCLK is the final CPU freq(Mhz) and it is a calculated value so do not set it as you want. It's value have to be calculate as follow :
    ARMCLK = MDIV X 24 / (PDIV × 2power(SDIV-1)

    where, MDIV, PDIV, SDIV must meet the following conditions :
    PDIV: 1 = PDIV = 63
    MDIV: 64 = MDIV = 1023
    SDIV: 1 = SDIV = 5
    (25/ PDIV): 1MHz <= (24/ PDIV) <= 12MHz

    Es. ARMCLK = 400 X 24 / (6 × 2power(1-1) = 1600(Mhz)

    DIVHCLKM is the divisor for main system frequency.

    HCLK_MSYS(main system frequency in Mhz) = ARMCLK / (DIVHCLKM + 1)
    Es(1600). HCLK_MSYS = 1600 / (7 + 1) = 200(Mhz)
    HCLK_MSYS must be <= 200 (Mhz)

    DIVPCLKM is the divisor for perimetral devices frequency.

    PCLK_MSYS(perimetral devices frequency in Mhz) = HCLK_MSYS / (DIVPCLKM + 1)
    Es(1600). PCLK_MSYS = 200 / (1 + 1) = 100(Mhz)
    PCLK_MSYS must be <= 100 (Mhz)

    DIVA2M is the divisor for 2d and 3d subsystem frequency.

    SCLKA2M( 2d and 3d subsystem frequency in Mhz) = ARMCLK / (DIVA2M + 1)
    Es(1600). SCLKA2M = 1600 / (7 + 1) = 200(Mhz)
    SCLKA2M must be <= 400 (Mhz)

    DIVG2D is the divisor for 2d graphic subsystem.
    DIVG3D is the divisor for 3d graphic subsystem.
    DIVMFC is the divisor for Multi-Format Codec.

    these values must be calculate as follow :

    SCLKG2D= SCLKA2M / (DIVG2D + 1)
    SCLKG3D= SCLKA2M / (DIVG3D + 1)
    SCLKMFC= SCLKA2M / (DIVMFC + 1)

    Es(1600).

    SCLKG2D(Mhz)= 200 / (4 + 1) = 40(Mhz)
    SCLKG3D(Mhz)= 200 / (4 + 1) = 40(Mhz)
    SCLKMFC(Mhz)= 200 / (4 + 1) = 40(Mhz)

    Just to try by your self the values for 1200 and 1000 are (1200,300,6,1,6,6,1,3,3,3) and (1000,250,6,1,4,4,1,3,3,3).
    To set your values at start-up crete a S_xxxxxx.sh script file as follow :
    #!/system/bin/sh

    echo "1600 400 6 1 7 7 1 4 4 4" > /sys/devices/system/cpu/cpu0/cpufreq/user_free_freq_values_table_L0
    echo "1500 375 6 1 7 7 1 4 4 4" > /sys/devices/system/cpu/cpu0/cpufreq/user_free_freq_values_table_L1
    echo "1400 350 6 1 7 7 1 3 3 3" > /sys/devices/system/cpu/cpu0/cpufreq/user_free_freq_values_table_L2
    echo "1300 325 6 1 7 7 1 3 3 3" > /sys/devices/system/cpu/cpu0/cpufreq/user_free_freq_values_table_L3
    ​

    - New script, S_set_cpu_thres_table.sh, inside S_scripts.zip file as an example to how change cpu threshold values

    Version 4_7_8 (2011-02-20)
    - Better Sharpness Again
    - Added Bonus scaling on conservative governor :
    Every two scaling up events a bonus up jump on upper freq is made to get more smooth
    Every two scaling down events a bonus down jump on lower freq is made to get better power usage

    ​
    Version 4_7_9 (2011-02-24)
    - Fix a bug that hangs phone when you disable the cpu state before the maximum
    - Add ext2 for System FS. IT DO NOT WORKS AT ALL. IS THE FS TYPE IS NOT SUPPORTED BY THE PHONE IN SOME WAY??
