Abstract
A virtual function (VF) driver is provided, which receives an indication of base address registers (BARs) exposed by an I/O device providing virtualized hardware resources for use by the VF driver. The VF driver performs an internal probe and analysis to determine a target adaptation of at least one of the BARs exposed by the I/O device. A physical function (PF) driver receives a request message from the VF driver to adapt at least one of the BARs exposed by the I/O device. The BARs exposed by the I/O device are adapted by the PF driver according to the request message. A confirmation message is provided to the VF driver indicating the adaptation to the BARs exposed by the I/O device. The VF driver accesses regions of memory allocated to the adapted BARs exposed by the I/O device.
