Which chipset you are using? ICH9 generally shall be better suited for
your needs, due to recent
PCI features support.

Hi all,
I'm working on a PDM virtual PCI device module and I need to have a
bar size of 512MB.
This particular PCI device uses bar 0 and 1 for register blocks (64KB
each) and bar 2 for memory (this one I need to be 512MB or even bigger).
Registering the memory bar using the MMIO2 functions fails when the
size is bigger than 256MB (hard coded limit in the allocation
function) so I tried registering using MMIO. It seems to work but my
read and write callbacks never get called (bar 0 and 1 also use MMIO
and their callbacks always get called). I tried decreasing the bar 2
size and the callbacks got called.
Is this even possible without modifying VBox source code? What am I
missing?
Thanks,
Jose
