Module Name:
|
|
|
|
UnixThunk.c
|
|
|
|
Abstract:
|
|
|
|
Produce UnixThunk protocol and it's associated device path and controller
|
|
state protocols. UnixThunk is to the emulation environment as
|
|
PCI_ROOT_BRIGE is to real hardware. The UnixBusDriver is the child of this
|
|
driver.
|
|
|
|
Since we are a root hardware abstraction we do not install a Driver Binding
|
|
protocol on this handle. This driver can only support one one UnixThunk protocol
|
|
in the system, since the device path is hard coded.
