- Hi UNIX freaks,
-
- first of all, I want write a X-server for a new graphic card.
- It's an autoconfig (Zorro2) card with two autoconfig regions
- (64kB+1MB).
-
- My first problem is now to create a /dev device for the card
- to mmap() the memory into the virtual memory.
-
- How can I do this?
- How can I create a dev file (or two?) which correspond to the
- autoconfig card? What changes (where) must I do into the kernel?
-
- Should I implement ioctl() calls for the device? How?
-
- (It's my first try to program at such a low level UNIX)
-
- Thanks for all hints!
-
- Georg.
-
- PS: I do have the UNIX version 2.03.
