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
