using lehto's for 2days, and everything is perfect so far.

loading of images in web browsing are 20% faster is what i mainly notice in OC @125/900mhz frequencies.

the gba emu is 1% faster specially in rendering audio.

while an app is running and idle or when charging, noticed that the freqs are dynamically changing @125 and 900 only (no 250, 500, 550).

All the info lays in the /usr/share/kernel-power-settings/ and depending on you run lv/ulv/xlv/ideal

In my case i did a "cp /usr/share/kernel-power-settings/xlv /usr/share/kernel-power-settings/my-xlv" and tweaking the my-xlv file. You can also twak the DSP here if you like.

wow things are moving so fast. ive been using lehto's 128-800 and its been ok. i want to try titan's kernels but they dont seem to be as noob friendly and i dont want to brick my phone. hopefully it will advance to the point where there will actually be a gui to mess with the setting instead of a bunch of scripts and commands.

It's pretty straight forward actually..

1. install from app-manager: kernel-power-flasher and kernel-power-settings. (For safety reset kernel to stock and backup all your data)
2. edit /usr/share/kernel-power-settings/ (and the preferred voltage) vl/ulv/xlv/ideal
3. run a test with: kernel-load /etc/share/kernel-power-settings/ (preferred setting)

after a reboot you will be back on default and need to run the kernel-load command again. You can make it permanent later when you are sure it works stable for you.

The "kernel-load /etc/share/kernel-power-settings/xlv" looks like this. Edit only the "min_freq" or "max_freq" if you just want to set the mhz. Vdd1_opps_vsel is for voltage tweaking.

Code:
#UP_THRESHOLD=75
#SAMPLING_RATE=150000
VDD1_OPPS_VSEL="20 20 30 33 38 38 45 45 48 48 54 54 60 67 72"
DSP_OPPS_RATE="90000000 90000000 180000000 360000000 400000000 430000000 430000000 430000000 430000000 500000000 500000000 500000000 500000000 520000000 520000000"
MIN_FREQ=250000
MAX_FREQ=850000
SMARTREFLEX_VDD1=0
SMARTREFLEX_VDD2=0

What about ignore_nice_load? Should it be included in the kernel-power-settings scripts also? Personally I don't think it's worth enabling but still.

thanks for the reply but I don't know what to tweak and btw whats the default values set when first installed?
I have installed and done sudo kernel-load /usr/share/kernel-power-settings/ulv and set the max cpu freq echoing 850000 to scaling_max_freq as its how I was doing before. Now as the frequencies for dsp are also various, do I have to set it like cpu or it happens automatically when setting cpu and tweaking is only required if I want something different from what is there? I mean somewhere I read titan saying >=850 cpu will be 500 dsp and 520 for 1.1 and 1.2 cpus, so tweaking is only required if I want to change this?
thanks

this package version doesn't exist. you mean kernel-power-flasher?
did you reboot after installation?
did you overclock or change some other settings?

Either busybox is really broken or I'm more stupid than I thought.

After installing the transition-package I symlinked the file - and later found out, that there was no file to be symlinked at all... I forgot to install the additional package. But busybox didn't gave an errormessage after the first attempt to symlink - that's really... "bad".

So - if someone has no errormessage, doublecheck if the symlink (the "ln -sf"-thing) was created correct...

yes. try
Code:
cat /sys/power/dsp_opps_rate
the next version of the settings package will have a command to summarize the current settings.
