How to change your frequency/governor before flashing?

!!!! READ THIS :) !!!!

​

That's new. Sounds strange, but it works. I am proud to present a truly innovative concept:

cmdline_khz / cmdline_gov / cmdline_maxscroff

What does this do for you?

Have you ever wished you could set the default min/max/gov/scroff frequency on your own?

Without having to rely on the dev to recompile?

Or doing it yourself?

Or even bothering to learn how to do that?

Or using OC apps that are just in the way?

(governor set able in setup from version 1.0)

Well, your prayers have been heard!

It simplifies any kernel install to the bare minimum. You download the zip, and just change the values to your liking. The kernel will obey you, it's magic!

you will download this file for example:

Bricked-3.0-v0.61-ics-maxkhz=1566000-minkhz=192000-maxscroff=432000.zip

now it is possible that you don't want to oc to 1566Mhz, or your preferred min freq is higher, or or or...

Just rename the file!

Bricked-3.0-v0.61-ics-maxkhz=1188000-minkhz=384000-maxscroff=540000.zip

The kernel will now boot from second 0 with this settings:

Max freq: 1188Mhz

Min freq: 384Mhz

maxscroff: 540Mhz

Cool, isn't it?

Now one could say, hell that's too dangerous, what if I write something wrong in there? No problem, your show-p1984 thought of everything. I have built in that much security measures that it is not even remotely imaginable that something could go wrong. I am serious. Whoever manages to break it gets a golden pile of **** from me.

Now what does it "autocorrect" exactly?

It corrects mhz instead of khz values for you, so you can actually flash this:

Bricked-3.0-v0.61-ics-maxkhz=1188-minkhz=384-maxscroff=540.zip

and it will still work.

Or it corrects wrong acpu frequencies. You can find a table @ the second post, but if you mistype sth, no fear, it will still work!

Bricked-3.0-v0.61-ics-maxkhz=1190-minkhz=390-maxscroff=545.zip

for example will let the kernel boot with 1188Mhz max and 384Mhz min (maximum screen off frequency 540Mhz). It always falls back to the next lower step. Actually you won't need to bother for the acpu table anymore, just type anything in there, it will automatically correct it for you! If you still want to enter the correct values, just look in the second post ;)

Now what if you write a letter in there? Like this:

Bricked-3.0-v0.61-ics-maxkhz=II88000-minkhz=38A000-maxscroff=5A0O00.zip

Well, the kernel will detect that and fall back to default settings read out of my .config. Which means the kernel will boot @ 1566Mhz max and 192Mhz min and maxscroff will be set to 1566Mhz (=disabled).

What to do if you just want to change your clocks?

Rename the zip file, boot into recovery, flash, and enjoy ;)

There is also a sysfs interface for the maxscroff frequency, for simplicity I kept the common name for it.

/sys/devices/system/cpu/cpu0/cpufreq/screen_off_max_freq

Currently there is only one limitation:

You can't have two files with the same base on your scard. that means:

Bricked-3.0-v0.61-ics-maxkhz=1566000-minkhz=192000-maxscroff=432000.zip
Bricked-3.0-v0.61-ics-maxkhz=1188000-minkhz=384000-maxscroff=540000.zip

are not allowed to be on the sdcard at the same time, the kernel would boot with defaults: 1566/192 if you flash either one of those files.

The "base" of the filename is this: Bricked-3.0-v0.61-ics-

So you can have 2 files (or more) on the sdcard with names like this:

Bricked-3.0-v0.55-b4-ics-****

Bricked-3.0-v0.7-ics-****

Bricked-3.0-v0.8-ics-****

(****=etc etc etc etc)

Furthermore it must be followed by maxkhz=VALUE-minkhz=VALUE-maxscroff=VALUE.zip It is not possible to switch the positions of the options. But you can leave them out of there completely, the kernel will then boot with 1566/192/1566.

Ah btw: We now see our set max mhz under Settings->About Phone->HW->Cpu ;) (it actually changes when you change your maxkhz)

And since 0.6 comes with the awesome Aroma installer you can now choose from 3 gpuoc versions!

GPU OC disabled, 3D@266Mhz & 2D@200Mhz

GPU low overclock, 3D@300Mhz & 2D@228Mhz

GPU high overclock, 3D@320Mhz & 2D@266Mhz + Bandwidth push

The source for this is split into two parts, Kernel & bash script. The script finds the zip on your sdcard, parses the filename and modifies the kernels cmdline inside the boot.img. The Kernel is parsing the cmdline, checking if everything is valid and setting your options.
​

How to install?

Just flash from recovery. Because it creates a boot.img out of the one on your phone while flashing, it should work with the majority of ROMs out there.

Interactive install, enjoy the ride! ;)
