Subject: [PATCH] vfio/iommufd: Implement HostIOMMUDeviceClass::realize_late()
|
||
|
|
handler
|
||
|
|
|
||
|
|
There are three iommufd related elements iommufd handle, devid and
|
||
|
|
ioas_id. ioas_id is ready only after VFIO device attachment. Device
|
||
|
|
id and iommufd handle are ready before attachment, but they are all
|
||
|
|
iommufd related elements, initialize them together with ioas_id.
