FramBuffer for ep9310 ARM Board

FramBuffer for ep9310 ARM Board

[Bhaskar]

Dear Team,

I need to modify modify Frame Buffer for ep9310 ARM board.  The
original frame buffer was provided by Cirrus Logic.  For the debugging
purpose, I introduced trace messages in frame buffer operation
functions like imageblit, fillrect, etc.

These messages appear only during Linux boot up and shutdown.  When I
move the window, none of the trace messages from the frame buffer
appears.  The Xserver used is XOrg-6.9

Somebody kindly provide a pointer from where to start inorder to
understand the flow functionlity of the existing framebuffer.

Regards.

The in-kernel frame buffer operation functions like imageblit, fillrect,
etc. are not used from userspace. X does all drawing itself.
