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:

Install Kernel :
1- download kernel
2- (Only Odin Version )turn off unzip file and use tar file as pda in odin and flash it
3- (Only CWM Version)go into CWM recovery and select install zip from sdcard, choose kernel CWM zip from sdcard and then install it

Apply Lagfix :
- after you installed kernel go into CWM recovery and select advanced ulk features-->Lagfix option and select your desire method and reboot your device

Apply root :

- JPX Kernel Aligned

- 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,DIV G2D,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
Good work to all.

What G++ compiler tuning options did you use?
And how did you measure the performance improvement?
- Backlight Notification (BLN) mods for Samsung Galaxy S i9000 - led notifications by touchkey backlight
- BLN control - blinking, call notification, scheduler, locale plug-in(s) and more
- SGS kernel flasher - flash a kernel from any .tar or .zip within android on Samsung i9000, Captivate, Fascinate, Vibrant and more.
