Subject: [PATCH] acrn/vhm: HC_ASSIGN_PTDEV passes the bdf directly instead of
|
|
guest physical address
|
|
|
|
Currently the HC_ASSIGN/DEASSIGN_PTDEV is called to add/remove the
|
|
pass-through device and the bdf is passed by using guest_physical_addr
|
|
mode. This requires that the ACRN hypervisor looks up the GPA mapping
|
|
to get the bdf. In fact it looks much simpler that it is passed directly.
