[Q] Question about smartass governor - Wildfire General

Hello,
I've flashed cyanogenmod 7.1 RC1 and immediately switched to using the smartass governor. However, I've noticed that the apps that can detect CPU speed (like SetCPU or OS Monitor) always detect frequency as 480 MHz. I've set the Max freq to 748 MHz and min to 245 MHz, but whatever I do, the frequency stays at 480 MHz. I've also seen in the messages section of OS Monitor errors about setting to 768000 from 480000, so I guess there is some kind of a problem there.
So is there a problem or does this governor work in a completely different way - if so, how? ;-)
Thanks a lot.
Cheers...

Smartass caps the frequency when screen on to 480 MHz to ensure responsiveness. This also helps with video playback being smooth, as it otherwise will begin to stutter when the frequency is lower than this.

OK, but how does it behave during screen off and battery low scenarios? Does it put the freq to to minimum value which is selected in the freq options of cyanogenmod setup?
I just want to understand if indeed the smartass governor can replace setcpu with profiles using the ondemand governor and keep the battery usage at optimal values.
Thanks...

When screen off smart ass governor sets the minimum CPU frequency to the value you entered (even below 480 which is to conserve the battery).

Bug in SetCPU or in Nexus kernel?

If I set the min cpu speed to the minimum (245MHz) using SetCPU and then refresh the CPU monitor, it's always at Max (998MHz).
However if I set the min to 384MHz and refresh, it's at 384 (unless something else is going on in the background in which case it might increase a bit).
This is all with the CPU governor set to on-demand
If I set MAX cpu to 245 then the monitor says it's 254, btw, so it seems it can run at that speed fine and the monitor is working ok apparently. It's just with min speed set to 254, it seem to stick at 998Mhz.
Does anyone else see this behaviour?
It this just a problem with SetCPU, or an underlying issue?
well, having played around with it some more, it seems it's actually the cpu speeding itself up so rapidly when monitoring it that it registers max MHz!
If I increase the up threshold, or the sampling rate, so that it doesn't step up a gear so quickly, then the monitor reads 245MHz.
This does raise the question though that if simply pressing the refresh button is enough to up the cpu to max when it's at the default settings, maybe there are better settings for battery life?
Maybe a slightly higher minimum speed is better, so that it doesn't step up all the time (because when it does, it seems to go straight to max).....

[Q] Best Overclock setup

Hello together,
first of all i would say that im completely new to this rooting and flashing stuff so dont be too hard to me. Lets start with my story: last year ive buyed my wildfire and used it for 2 months without rooting it. fast i've seen that it would be much more easier for me if i start rooting and flashing it with a custom ROM. Wildpuzzle was the first ROM i've ever used on this phone and i didn't updated it for a long time because i thought i can do anything bad to my phone. 3 days ago i've felt very bored so i read myself once again through all of the tutorials and FAQs. I decided to search the forum for a new ROM without sense so i picked CyanogenMod 6.1 because i wanted a stable ROM which dont reboot 4 times a day(like my old Wildpuzzle one). Today I wanted to speed um my phone and read through some posts and found out that I can overclock my wildfire with SetCPU. I've never overclocked a phone or a pc so i dont know what setup is good for it or which is not.
And thats my question: HOW should i do this and with what cpu setup(min/max) for a stable working phone.
PS: as i've read through the overclock posts i've found out that my phone is already flashed with a overclocking kernel(2.6.32.21-HCDRJacob)
PPS: i'm excuse myself for my bad english and hope you all can understand what i mean
Depends on your preferences really. For me, on my SetCPU Normal Profile, I have set it as 614 MHz Max and 245 MHz on Min, Interactive Scaling. Apart from that, I have also set the following profiles:
1: Screen Off - Max 352, Min 245
2: Temp >46C - Max 352 Min 245
3: Battery <20% - Max 480 Min 245
I had set the minimum earlier to 122, while it gave me awesome battery life, the phone would hang whenever I got an incoming call / message (CPU too slow to handle it), hence, after several experiments, I have found it to be stable at 245. For Max, you can keep it upto 710 MHz, but, I wont recommend a speed beyond that for 24x7 usage. For short purposes (like playing a game, benchmarking etc.), you can go till 768, or the max your phone is stable at.
Amazingly my set up is nearly identical to 3xeno but my max in normal profile is 691 MHz

so what is exactly the interactive scaling ??
what is the difference between ondemand, userspace, performance, interactive...
while searching for the answer ... i also saw pple tlking about powersave and conservative scaling ... i dont have these options ... :s
Sorry to butt in but since we are on the subject of overclocking etc and I dont want to make another thread. Is that setcpu app from the market any use on my wildfire? its not rooted.
No you need rout access to change frequencies mate.

What, your settings are extractly like me, lol
are you referring to old wildpuzzle 8.0.11, i got freezes with that, but after changing to new wildpuzzle, i have not had one freeze or reboot with settings below.
set on performance

Thank you for sharing this information, I changed mine to this too. Can I ask if you 'Set on Boot' on the main profile? I think you would, but I thought i better check!

I usually set my speed to Max 710, Min 480 Ondemand, no profile. I think it's interesting to try your setting. Thanks for sharing.

[Q] Why doesnt my phone underclock to 122.88mhz

Has anyone else noticed this? My phone only goes to 245 mhz for idle speed. Android system info said that the cpu can go as low as 122mhz. I think it would save some battery life right?
yes we can... but you need root acces and setcpu
and you can underclock
PM me if you need more help
i suggest dont do that..
i ever do that, n phone become slowly ..
even to open setting..
it will become slow like symbian, and what ur friends think about it??
maybe they will thinking, android very slow :|

what ROM are you using? I'm using racht's floyo 0.15 and when the screen goes off the cpu idles at 122 MHz well.
or maybe you checked cpu freq when screen is on? because it's not 'idle' state.
This sounds interesting - can you guys let me know if you manage to extend battery life with this... and how much by, daily charging is sucky!
I use setcpu with this configuration:
Max: 600000
Min: 122880
Scaling ondemand
check: set on Boot
I also create profile:
Screen Off
Max: 320000
Min: 122880
Scaling ondemand

SetCPU Settings

I need suggestions to setup good config in SetCPU i have kyrilos rom 7.5 beta and Galaxy 3 phone of course. thanks
There is option to automatically detect optimized setting.You can create profiles and enable them.Setting speed to powersave mode while charging and while screen off saves lot of battery.You can still experiment and see what suits for you.By the way setting some extreme values might affect life of your phone so be careful.
It is strange but in setcpu on my galaxy 3 conservative mod is not working. So ichoose userspase

Try latest version it works for me.Maybe you can try rebooting phone see if it works then.
Use 400Mhz-800Mhz on demand for battery.
Go to full 1300Mhz for performance but this will drain battery

[Q] about CM 7.1 Performance Settings~

hmm, may i ask about :
CM7.1 performance settings:
CPU Settings :
Available Governors
1.hotplug
2.ondemand
3.userspace
4.performance
as i know performance is keep the CPU run at maximum. how about hotplug, ondemand(default) and userspace, which one should i select??
-----------------------------------------------------------------------------
And what the best Min CPU Frequency set ?? 300Mhz (default) or 600Mhz???
Thank you~~~~~
I leave mine set to ondemand set max to 1300 and set the min. to 600 because when I set my min. to 300 I would get the sleep of death.
So far with my min. set to 600 I have gone a full 24 hrs. with no SOD and it seems to have not had any ill effects on battery life.
if you want to know more about the specific governor options you can read the cpufreq configs, for example
https://github.com/intersectRaven/kindle-kernel/blob/master/drivers/cpufreq/Kconfig
will show you the configs for intersectRaven's kernel.
honestly until someone tests each of these on an array of frequencies it's hard to know which is actually best. obviously the previous statements regarding sod are more than valid points.
