The way the size is reported by the BAR register by checking if the device
decodes certain bits or not implies that the address must be naturally
aligned, i.e. aligned to the size.

Hello Wannes,
Sorry, I don't think that's possible, because there's no way you can
set up a 32 bit BAR to point to anywhere higher than 4GB. The only

Hello Daniel,
No, unfortunately this cannot be changed. So there is no possibility
to map the 32 bit BAR in a higher memory region (where the 64 bit
BAR’s are located)?
Kind regards,

Hello,
For a device with such a big 32 bit BAR, it would be a challenge to fit
it inside the 32 bit window, since the RAM region available on <4GB must
be specially tuned with help from the emulator (which, as far as I am
aware, isn't available) to give space for BAR allocations there. Is
