bus_activate_resource(9) -- activate or deactivate a resource
|
|
These functions activate or deactivate a previously allocated resource. In general, resources must be activated before they can be accessed by the driver so that the bus driver can map the resource in... |
|
bus_alloc_resource(9) -- alloc resources on a bus
|
|
This is an easy interface to the resource-management functions. It hides the indirection through the parent's method table. This function generally should be called in attach, but (except in some rar... |
|
bus_child_present(9) -- ask the bus driver to see if this device is still really present
|
|
The bus_child_present() function requests that the parent device driver of dev check to see if the hardware represented by dev is still physically accessible at this time. While the notion of accessib... |
|
BUS_CONFIG_INTR(9) -- Configure interrupt polarity and trigger mode
|
|
The BUS_CONFIG_INTR method allows bus or device drivers to provide interrupt polarity and trigger mode to parent busses. This typically bubbles all the way up to the root bus (e.g. nexus) where the ne... |
|
bus_deactivate_resource(9) -- activate or deactivate a resource
|
|
These functions activate or deactivate a previously allocated resource. In general, resources must be activated before they can be accessed by the driver so that the bus driver can map the resource in... |
