My board is based on 2.6.24,I have tried to use 2.6.29 or27,but it
seems very difficult to fixed the driver problem，so I choose
2.6.25（release r1）--- diff the android2.6.25 from standard 2.6.25 and
then patch it to my board's given kernel 2.6.24.7
1.
I hacked the touch driver as follows：
first use tslib to get the pointercal file and then add it to s3c-ts.c
for calibration,like:
xtmp = (axis_table[2] + axis_table[0]*x +
axis_table[1]*y )>>axis_table[6];
ytmp = (axis_table[5] +
axis_table[3]*x + axis_table[4]*y )>>axis_table[6];
printk("x (xtmp)-> %d (%d)\t y(ytmp) -
> %d (%d)\np->%d\n",x,xtmp,y,ytmp,p);
input_report_abs(d->idev, ABS_X,ytmp);
input_report_abs(d->idev, ABS_Y,xtmp);
input_report_abs(d->idev,ABS_PRESSURE,
p);
input_report_key(d->idev,BTN_TOUCH,1);
input_sync(d->idev);
2.
and I hacked the android source code 1.6 as follows:
1 --- services/jni/com_android_server_BatteryService.cpp-orig
2009-11-01 18:20:41.000000000 +0800
2 +++ services/jni/com_android_server_BatteryService.cpp

Now，the board can boot up，but wherever I tap，it just respond at top
bar，I can see the date and time.
4.
Some one said that I should enable the following:
PM
Power Management support
Suspend to RAM and standby
Wake lock
Wake lock stats
Userspace wake locks
Early suspend
User-space screen access -> Sysfs interface
5.
and someone said the hack the PowerManagerService.java
boolean screenIsOn() {
synchronized (mLocks) {
- return (mPowerState & SCREEN_ON_BIT) != 0;
+ return true;
if I do it ,the sceen will respond nothing!
since 2.6.25 have none of them ,so I copied the source files from
2.6.27 to 2.6.24 ,reconfigured and rebuild the kernel.
BUT,It is a pity that the ts still only responds at top left bar.

here are part of logcat：

so Could you tell me how to solve then?
Thank you !
