[MODULES][GSM] Smartass & Interactive CPU Gov for Gingerbread [Patch Included]

[-Mr. X-]

100% tested and working!
FLASHABLE ZIP ATTACHED
Patch For GT-P1000 GB Source Attached

Smartass CPU Gov is tweaked by me to behave properly on the SGT and ill assume it works on the SGS. I was running this module (well i built it in to the overcome kernel source) on Froyo just fine. No Ramping issues. It has been modified a fair bit by Ziggy471 originally for my Bravo, and now has a working sysfs interface to change settings on the fly. Ramp up and down steps should always be multiples of 128000, this is default set at 256000 which i have found to be optimal. I would not recommend touching any of the other defaults i have set.

Interactive Gov has been modified to load properly with direction as its not finding a symbol. Smartass depends on Interactive.ko


To install:

Push to /system/lib/modules obviously and run these commands in an adb shell or via device terminal:

insmod /system/lib/modules/cpufreq_interactive.ko
insmod /system/lib/modules/cpufreq_smartass.ko

init.d:

add these lines to an existing init.d script or download the one attached, and remove.txt from it. Push it to the device and chmod 755 it.

insmod /system/lib/modules/cpufreq_interactive.ko
insmod /system/lib/modules/cpufreq_smartass.ko

Big thanks to Ziggy471 for helping me with my C code, and af974 and crisvillani for being the testers since my tab is busted!

Patches Are attached, one labled with GINGERBREAD was made from the newly released Galaxy Tab Gingerbread source. It is assuming that the kernel devs will include the 600MHz frequency so the table conforms to =< 250MHz step up or down on each level of frequency. Otherwise They will have to define 800MHz as a skipped frequency in the config when compiling the kernel. I have made the patch to also export the nr_running symbol in sched.c which is needed by both interactive and smartass.

I'm going to test it right now, thanks for sharing though.

 

[-Mr. X-]

Thanks, i would have liked to test them make sure they behave properly. But i'm unable to.

 

[af974]

I don't know what i'm doing wrong but i can't insmod it, get: " unknow symbol in module or invalid parameter.Any advice?

Note: I have it under System/lib/modules

The module is probably borked then, I will investigate. Does Interactive work?

If neither do i will pull them both.

can you do a dmesg and post it?

 

[af974]

i'm testing it, wait a bit for a reply.

[af974]

Interactive zip is empty, you forgot it

 

[-Mr. X-]

Interactive zip is empty, you forgot it

LOL damn, its fixed now and uploaded

also

dmesg | grep smartass

would be better to run to see what its complaining about when you try to install it.

 

[af974]

Dmesg attached.

[af974]

I'm getting the same error with interactive, it could be that i'm doing something wrong?
I'm doing all by terminal, i'm gonna try another terminal app.

Well thats not good, Smartass depends on interactive, i had a brain fart there and forgot to mention that. this is why i posted both in one shot.

But if you cant get interactive to install then you wont be able to get smartass too.

If you want to throw me a dmsg of the interactive as well fi you cant get it to install. and i don't think you are doing anything wrong.

 

[af974]

This is dmesg for interactive:

dmesg | grep interactive
[ 2593.847022] cpufreq_interactive: Unknown symbol nr_running (err 0)

 

[-Mr. X-]

This is dmesg for interactive:

dmesg | grep interactive
[ 2593.847022] cpufreq_interactive: Unknown symbol nr_running (err 0)

Thank you, let me investigate this, thanks for the help!

 

[af974]

Anytime buddy, thanks to you for this, i'm waiting for smartass from a long time.
Take your time, i will check this thread for any news and i will test asap.

Alright i recompiled unstripped versions.

These should work. Install in the order you see on first post

I hope lol

No luck my friend

alright i think i may have actually tracked the issue down with interactive atleast. nr_running was undefined, the modules build fine with make modules but it threw the error if i atempted a full build.

so that should take care of the dmesg issue for that, unless its undefined in this kernel was compiled wiht it undefined in sched.c in if thats the case then i will have to work around that.

We could also try using richardtrips interactive module for the desire, just change the versionmagic. If this fails.

 

[-Mr. X-]

Alright attempt 3 is up, hope they suck less.

 

[crisvillani]

Don't mean to be a noob, but it seems may tab doesn't have a system/libs/modules folder

Will it work if i just create one or am I missing something ?

 

[af974]

Same as before with 3rd attempt.....sorry bud.
