Description: Sets the device address to be used for read or write through

PCI bar, or the device VA of a host mapped memory to be read or
|
|
written directly from the host. The latter option is allowed
|
|
only when the IOMMU is disabled.
|
|
The acceptable value is a string that starts with "0x"

|
Description: Allows the root user to read or write directly through the
|
|
device's PCI bar. Writing to this file generates a write
|
|
transaction while reading from the file generates a read
|
|
transaction. This custom interface is needed (instead of using
|
|
the generic Linux user-space PCI mapping) because the DDR bar
|
|
is very small compared to the DDR memory and only the driver can
|
|
move the bar before and after the transaction.
|
|
If the IOMMU is disabled, it also allows the root user to read
|
|
or write from the host a device VA of a host mapped memory
