I'm trying to overclock the gpu to 512, when I type oc gpu 2 in terminal I get sh: oc: not found I'm using kernel 3.1.0 exp 2. Thanks in advanced!

Where did you get that from? That version has not been released yet and there is no reference to that instruction. It will be set with sysfs not a script.

The release version actually has a script called "oc" that wasn't in the test version. I wrote the FAQ first and ThehulKK caught it before I officially released 3.2.0. ;)

I'm going to wait for a new EXP build, I want SoundControl and it seems that it isn't in the Stable builds.

Haha yeah I see the FAQ entry now. Make me look like a liar. :P

leanKernel v3.2.0

1) Introducing... Variable GPU OC! This will allow you to dynamically change your top GPU speed between 307mhz (stock-default), 384mhz and 512mhz. Check the FAQ on how to use it.


(from the faq) or use the built-in "oc" script

Is this a dynamic max based on load (similar to cpufreq for the OMAP) or something different?

Thanks
Gary

3.2.0exp1 is also up. Aside from Variable GPU OC, it also adds Gamma control (beta).

To use gamma control, open terminal, type "su" without quotes, enter, and then type:

echo "[number between 0 and 10, inclusive]" > /sys/devices/platform/omapdss/manager0/gamma

0 disables gamma control
5 is stock value

So for example:

echo "6" > /sys/devices/platform/omapdss/manager0/gamma

will produce a slightly darker picture. manager1/gamma and manager2/gamma will control external displays.

I think "dynamic" was the wrong word choice there. I'll fix that. It will basically just select the max speed between the three choices that are available.

Hey imoseyon, I tried the oc gpu function and both 1 and 2 set it to 384mhz. I also get terrible screen draw tearing and lag when I use the feature. Any idea what might be the issue? Running Liquid 1.25 and using leantweaks as well. This occurred on 3.2.0 stable, going to dl and try exp1 now.

interesting. You may have a phone that can't OC GPU to 512mhz. Run this command and send me the output?

dmesg | grep gpu

GPU OC is overrated, IMO, anyway. ;) I think going from 384Mhz to 512Mhz you only get about 10% performance boost due to factors outside the gpu module.

leanKernel v3.2.0

1) Introducing... Variable GPU OC! This will allow you to select your top GPU speed between 307mhz (stock-default), 384mhz and 512mhz. Check the FAQ on how to use it.
2) Linux 3.0.27 update
3) Some lowmemkiller updates from mainline Linux
4) interactive (and iX) speed enhancement patches from android source.
5) a couple of somewhat experimental battery saving patches (already tested in exp builds)
6) and more smartreflex fixes from omap source
7) "so" - script to toggle your screen-off max between stock 700mhz and your max speed (credit bjn)
8) remove more code for leaner kernel

I believe everything except for Variable GPU OC was already in 3.1.0exp2. Stay tuned for 3.2.0 experimental builds which will have another cool feature not in stable.


awesome, IMO! I'll give it go today. Some cpu utilities allow for screen-off profiles. Is the 'so' script similar in that regard? Also, I did notice governor(Interactive) would stay essentially pinned at 700mhz if min was set to 700mhz in earlier kernels. I think that was resolved in 3.1 exp2 though.

As far as off-screen behavior goes, is there an easy way to force it not to go below the minimum - unless it's sleeping. The only benefit 'could' be some of the tethering / mobile data disconnects people are experiencing with the release of 4.0.4 imm76.

Thanks again!
