33Description:    Allows the root user to read or write directly through the
34                device's PCI bar. Writing to this file generates a write
35                transaction while reading from the file generates a read
36                transcation. This custom interface is needed (instead of using
37                the generic Linux user-space PCI mapping) because the DDR bar
38                is very small compared to the DDR memory and only the driver can
39                move the bar before and after the transaction

103                e.g. to display info about VA 0x1000 for ASID 1 you need to do:
104                echo "1 0x1000" > /sys/kernel/debug/habanalabs/hl0/mmu
