[Kernel] Ziggy471 MECHA BETA Kernel UPDATED 3 May 11

Hey Ziggy. I am really liking the new toggle frequencies on and off feature. I made a script to disable the frequencies I dont use but one issue I'm having and it's not a big one is I can't disable the min and max that is set on startup (ex. 122 MHz min and 1.037 GHz max). Every other frequency is disable except those 2. This is the script I made to disable certain frequencies.

#!/system/bin/sh
echo 24576 > /sys/devices/system/cpu/cpu0/cpufreq/user_freqs
echo 61440 > /sys/devices/system/cpu/cpu0/cpufreq/user_freqs
echo 122880 > /sys/devices/system/cpu/cpu0/cpufreq/user_freqs
echo 184320 > /sys/devices/system/cpu/cpu0/cpufreq/user_freqs
echo 1036800 > /sys/devices/system/cpu/cpu0/cpufreq/user_freqs
echo 1113600 > /sys/devices/system/cpu/cpu0/cpufreq/user_freqs
echo 1190400 > /sys/devices/system/cpu/cpu0/cpufreq/user_freqs
echo 1267200 > /sys/devices/system/cpu/cpu0/cpufreq/user_freqs
echo 1344000 > /sys/devices/system/cpu/cpu0/cpufreq/user_freqs
echo 1420800 > /sys/devices/system/cpu/cpu0/cpufreq/user_freqs
echo 1497600 > /sys/devices/system/cpu/cpu0/cpufreq/user_freqs
echo 1574400 > /sys/devices/system/cpu/cpu0/cpufreq/user_freqs
echo 1651200 > /sys/devices/system/cpu/cpu0/cpufreq/user_freqs
echo 1728000 > /sys/devices/system/cpu/cpu0/cpufreq/user_freqs

Since I'm ranging between 192 MHz to 960 MHz, is there anyway to tweak it to disable those 2 on boot?

And one more issue I am having is the proximity sensor. It does not seem to be working correctly for me. Not sure if its because you lowered the voltage or its because I am extremely undervolted by almost 100 mV from your voltage table or even 100+ mV on certain frequencies. This is the script I am running for vdd levels just to show you how low I am undervolted.

Since I am new at this, how do you create the script and where do you place it? Plz?

Really simple fix, add these two lines at the beginning of the script to shut off the frequencies:
echo 192000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
echo 960000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

EDIT: I'd also recommend using the added feature of disabling all freqs outside of the policy, it'd be a much cleaner script.

I'm assuming that your using SetCPU to set the freqs for you, with adding those two lines, there's no need to use it anymore.

The answer is in the OP, I did a write up about it on my site awhile ago.

So if we change the freq we use by issuing these comands, we dont need to use SetCPU anymore? Except if we want to see what it is acutally running at?

Yep, that's correct.

Will try this tonight. Also the reason why I created the script that way is because I am also going to disable certain frequencies between my 192 MHz and 960 MHz range as I see my phone doesn't utilize the 806 Mhz and 883 Mhz frequencies. Thank you.

@ Ziggy

Just edited my script to include the min/max code you provided and it worked like a charm. Thank you for your help.

Glad to hear it.

Whoaaa!!! I downloaded ziggy's 5-3 from his 5-1 and I am SOOOO confused!! This one is to brilliant for my noobie brain.
I'm stuck between 120 and 1036. I thought I would be smart enough to handle this but NO WAY!!
I'm restoring back to the wonderful 050111.

I have brain ache!!!
