I did dirty hack: insert msleep(1) after each input thread synchonization in mcs6000 driver.
Now hack is not dirty, just found that driver has native implementation of "sleep".
Result: 15-30% cpu use with tap down.

Included all tweaks from GNM OC Kernel.
Packaged in koush's anykernel for compatibility with any rom.

Do not forget to make nandroid backup first.

Probably fixed "scroll bug".

v1.1: added pressure sensitivity (works correctly only for single touch because of our touchscreen).

No. Only apply kernel.zip via recovery (that flash new kernel).

About unsigned zip files

You can flash unsigned zips. In the recovery menu just select Other -> Toggle Signature Verify. It will disable this verify.
About this hack. It's working. BUT the scroll works buggy now. For example, you cannot make the contacts menu scroll from the beginning to the end fast now

I would not say that it became too buggy, only a little bit (very little). And maybe you have too much contacts in youe contact list

miki, is it possible insert some double or something with float value? I mean if it is possible do less that 1 millisecond? For example msleep(0.5)? It will be faster for scrolling, but will not do loop on touch.


//Edit:

It should be possible... http://www.handyboard.com/oldhb/software/icmanual/node86.html


//Edit2:
or maybe use usleep(microsecond)

We can't use usleep in kernel level code because it is libc function. And msleep accept only integer (int/long).

The bug in our phone is not related to famous bug in android issue tracker. And my hack is little bit crappy
