Hi,<BR>
<BR>
I am working a Xorg graphic chip driver, but find some bugs(Xorg crashed while switching between X windows and console). So I need a Xorg server with debug info. That's why I want to compile Xorg.<BR>
<BR>
The original Xorg which came with Debian got IOPortBase assigned correctly which means that resource of my graphic chip is ok.<BR>
<BR>
The problem is my driver used function outb() which was defined as :<BR>
static __inline__ void<BR>
outb(unsigned PORT_SIZE port, unsigned char val)<BR>
{<BR>
*(volatile unsigned char*)(((unsigned PORT_SIZE)(port))+IOPortBase) = val;<BR>
}<BR>
Just found that IOPortBase wasn't set correctly.<BR>
As I found that IOPortBase was only set in the file arm_video.c, I think that outb() shouldn't be as above. There are several different version of outb(). So I just think that maybe I should do some extra work to let Xorg find correct version of outb().<BR>
<BR>
