Iam trying to integrate the xfree video driver for my PMC graphics card ..

I need to debug the video driver.. ( reg its IOBASE,mem base etc)
I added printf inside the driver but it is not coming in var/log
Please give idea how to add some debug statements(with variable values)
inside the video driver such that it will come in var/log ...???
The server closes stdout as part of its initialisation. You could use
stderr instead, but it is preferable to use the xf86Msg() family of
functions. These are documented in section 18.1 of the DESIGN document.
Still, I could not find where my video driver access bad area.
As said earlier iam using the PMC graphics card along with a base board.
while integrating the frame buffer driver for the graphics, based on
our architecture
FOR I/o READ/WRITE ACCESS I should use as
outb(val,port) as outb(val, 0xF200+port)
inb(val,port) as inb(val, 0xF200+ port)
I have modified the direct I/O accessing in the xfree in my video driver
...
Shall i need to modify the same in compiler.h inside
programs/Xserver/hw/xfree86/common ??
I suspect the problem is closely related to I/o issue only
I have attached the log file and the serial port messages for ur
reference ..
Please shed me some light to solve the issue..
Thanks a lot
