The the bdf(bus/dev/func) is used to determine which pass-through device should be assigned/released. Now the hypervisor parses the corresponding bdf from the guest physical address when hcall_assign_ptdev/hcall_deassign_ptdev is called. As it is only uint16_t, it is unnecessary to use the GPA to pass the bdf parameter. Instead the parameter can be used as the bdf directly. In order to keep the compatibility, it still can get the bdf by using copy_from_gpa when SOS passes the parameter based on the buffer. But this will be depreciated. This is based on the assumption that the GPA in SOS is greater than 0x10000 when one buffer is allocated to pass the corresponding hypercall parameter. After the SOS uses the bdf to pass the hypercall paremeter, we can remove the code that gets the bdf by using copy_from_gpa. V1->V2: Add some comments for hcall_assign_ptdev/hcall_deassign_ptdev.

Embedded-Hypervisor ################### This open source embedded hypervisor defines a software architecture for running multiple software subsystems managed securely on a consolidated system (by means of a virtual machine manager), and defines a reference framework Device Model implementation for devices emulation This embedded hypervisor is type-1 reference hypervisor, running directly on the system hardware. It can be used for building software defined cockpit (SDC) or In-Vehicle Experience (IVE) solutions running on Intel Architecture Apollo Lake platforms. As a reference implementation, it provides the basis for embedded hypervisor vendors to build solutions with an open source reference I/O mediation solution, and provides auto makers a reference software stack for SDC usage. This embedded hypervisor is able to support both Linux* and Android* as a Guest OS, managed by the hypervisor, where applications can run. This embedded hypervisor is a partitioning hypervisor reference stack, also suitable for non-automotive IoT & embedded device solutions. It will be addressing the gap that currently exists between datacenter hypervisors, hard partitioning hypervisors, and select industrial applications. Extending the scope of this open source embedded hypervisor relies on the involvement of community developers like you!
