I'm working on building a v4l2 driver for an FPGA module on a Xilinx
Virtex4 PPC.
Question:
Why does the v4l2 videobuf *depend* on PCI?
Rob.

You could try dropping the dependency from Kconfig and see what breaks
when you compile the core v4l2 stuff.
Cheers,

That does work and nothing seams to be broken just yet.
I also removed the dependency from the vivi (virtual video) module and
that modules works fine.
However, I tried to enable PCI support and that failed with undefined
PCI addresses. (duh. I have no PCI on the board)

Historical reasons I guess. The videobuf module has been designed for PCI
hardware (bttv if I'm not mistaken). Now that other, non-PCI devices would
benefit from videobuf, PCI-specific support is being moved to a separate
module.
Search the video4linux mailing list archive for discussions about videobuf
cleanup. You can get the latest source tree at www.linuxtv.org.
