2009-04-21 09:45:46 Possible memory leak

Hi,
I noticed that the ftree memory size decreases when I touch the screen...
Using:
Linux version 2.6.28.7-ADI-2009R1-pre (root@dlnx764) (gcc version 4.1.2 (ADI svn)) #391 Tue Apr 21 10:33:52 IST 2009
and BF527 EZKIT
I have "top" running to display the memory usage. When I move a pointer over the screen the free memory decreases with about 57.6K/sec.
Can anybody comment that, please, and help me to solve it?
Best regards,
Nikolay

Are you using the BF527-EZKIt on board Maxim touch screen digitizer?

Hi Michael,
Yes, that's exactly what I'm using.

Message: 72999 I guess you have to ask whoever wrote the driver for it.
- I know that there are no such issues when using the AD7877 or AD7879
touchscreen controllers.

...so, it seems to be in the MAX's driver. Thanks for pointing me, Michael.
Best regards,

I just noticed that this 'leak' comes from "/var/log/messages". It has been fluded by something like:
blackfin user.debug kernel: evbug.c: Event. Dev: input0, Type: 0, Code: 0, Value: 0
What is 'evbug.c' for? How can I solve that?

Turn it off.
