Module Name:

WinNtThunk.c
|
||||
|
||||
Abstract:
|
||||
|
||||
Produce WinNtThunk protocol and it's associated device path and controller
|
||||
state protocols. WinNtThunk is to the NT emulation environment as
|
||||
PCI_ROOT_BRIGE is to real hardware. The WinNtBusDriver 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 WinNtThunk protocol
|
||||
in the system, since the device path is hard coded.
