how to test framebuffer driver

Hello all,

my task is to write frame buffer driver.
can someone provide me some material for - how to remove the existing
framebuffer driver and place mine when testing it. Is these any other
way i can test my framebuffer driver.

Are there any applications which can directly run on framebuffer driver
other than X server.
If yes, what r they and how can I test my framebuffer driver using them.
If no, how can I test the fb driver using X server.

Please send all notes, corrections and additions to me regarding the
framebuffer drivers.

Can I write an application by directly opening my fb device and
performing operations like read/write/ioctl on it.

					OR

Are there any functions for the following list of fb_ops function
pointer.
I mean when they will be called. r there any system calls for calling
them.

 
regards,
mukund jampala

Yes you can, see here
"http://cvs.sourceforge.net/viewcvs.py/wyodesktop/wyoDesktop/checkdfb/src/app.cpp?view=markup"
or here
"http://cvs.sourceforge.net/viewcvs.py/linux-fbdev/fbtest/main.c?view=markup".
You are welcomed to enhance either test or even write your own. Best if
you look at this thread as well "http://sourceforge.net/mailarchive/forum.php?thread_id=5445188&forum_id=2357".
