MemoryRegionOps callback sizes

Hello,

Im new to qemu and trying to update a project that developed before me ! I have a question, thanks for help.

Memory allocation is done using MMIO and its created 64 bits bars for it. And while accessing pages I wish to see 8 bytes at read / write callbacks but 4 bytes are used.

I wish to learn how to edit this ? How can we set MMIO will use 64 bits = not 32 bits ?

( I hope I can explain = sorry )

Thanks
