|
|
|
|
|
.Fx
|
2002-12-10 14:21:55 +00:00
|
|
|
provides machine-independent bus support and raw drivers for
|
|
|
|
|
.Nm
|
2002-09-13 12:31:56 +00:00
|
|
|
interfaces.
|

|
|
.Pp
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
driver consists of two layers: the controller and the
|
|
|
|
|
bus layer.
|
|
|
|
|
The controller attaches to a physical bus
|
|
|
|
|
(like
|
|
|
|
|
.Xr pci 4 ) .
|
|
|
|
|
The
|
2002-12-10 14:21:55 +00:00
|
|
|
.Nm
|
|
|
|
|
bus attaches to the controller.
|
2003-12-17 01:13:13 +00:00
|
|
|
Additional drivers can be attached to the bus.
|
2002-09-13 12:31:56 +00:00
|
|
|
.Pp
|
|
|
|
|
Up to 63 devices, including the host itself, can be attached to
|
2002-12-10 14:21:55 +00:00
|
|
|
a
|
|
|
|
|
.Nm
|
|
|
|
|
bus.
|
2003-12-17 01:13:13 +00:00
|
|
|
The root node is dynamically assigned with a PHY device function.
|
2002-12-10 14:21:55 +00:00
|
|
|
Also, the other
|
|
|
|
|
.Nm
|
|
|
|
|
bus specific parameters,
|
|
|
|
|
e.g., node ID, cycle master, isochronous resource manager and bus
|
2003-01-25 15:24:59 +00:00
|
|
|
manager, are dynamically assigned, after bus reset is initiated.
