Advanced overclocking for DroidX

If you know your way around android terminal, overclocking your Droid X without a helper app is really not that difficult.  Here are the steps:

1. Download and install Milestone Overclock (this is just so you can grab the kernel module).
2. Find overclock.ko from the milestone directory and move/copy it over to /system/lib/modules.  You can optionally uninstall Milestone Overclock now - you no longer need it.
3. Run the following script (be sure to substitute A, B, C, D with your own vsels, and W, X, Y, Z with your own frequencies).
   
   #!/system/bin/sh
   insmod /system/lib/modules/overclock.ko
   echo 0xc05a8dcc > /proc/overclock/mpu_opps_addr
   echo 0xc0048a00 > /proc/overclock/omap2_clk_init_cpufreq_table_addr
   echo 0xc059b258 > /proc/overclock/cpufreq_stats_table_addr
   echo 0xc02d1104 > /proc/overclock/cpufreq_stats_update_addr
   echo D > /proc/overclock/max_vsel
   echo Z00000 > /proc/overclock/max_rate
   echo 1 W00000000 A > /proc/overclock/mpu_opps
   echo 2 X00000000 B > /proc/overclock/mpu_opps
   echo 3 Y00000000 C > /proc/overclock/mpu_opps
   echo 4 Z00000000 D > /proc/overclock/mpu_opps
   echo 0 Z00000 > /proc/overclock/freq_table
   echo 1 Y00000 > /proc/overclock/freq_table
   echo 2 X00000 > /proc/overclock/freq_table
   echo 3 W00000 > /proc/overclock/freq_table

My values: W = 3, X = 6, Y = 9, Z = 12, A = 22, B = 33, C = 48, D = 63

If you want the new settings to stick at boot, you'd want to put the script in /etc/init.d somewhere.  You can name it 99overclock or something like that.

As for how you can determine the best frequencies and vsels, you'll have to experiment.  If you're lazy, I recommend using something like Quickclock - the developer, Paul, is an awesome guy. :)

Finally, here's a nice trick.  The numbers in the following file will tell you your usage pattern per frequency:

/sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state

Here's an example:

bash-3.2# cat  /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state
1200000 1424737
900000 87456
600000 182945
300000 4688410

You will notice that your phone spends most of the time at the lowest clock frequency and rarely will it use the middle ones.  Interesting, but expected.
