<div dir="ltr">Hi all,
<div><br>
</div>
<div>
<div>I'm working on a PDM virtual PCI device module and I need
to have a bar size of 512MB.</div>
<div>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).</div>
<div><br>
</div>
<div>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.</div>
</div>
<div><br>
</div>
<div>Is this even possible without modifying VBox source code?
What am I missing?</div>
<div><br>
</div>
<div>Thanks,</div>
<div>Jose</div>
