do_config(9r) do_config(9r)
NAME
do_config - EISA/ISA: Initializes the device to its assigned configuration
SYNOPSIS
void do_config(
struct controller *ctlr_p );
ARGUMENTS
Specifies a pointer to the controller structure associated with the controller to be configured. The do_config routine obtains the device
to initialize through its controller's associated controller structure pointer.
DESCRIPTION
The do_config routine initializes the specified controller based on its power-up resource assignments. If the device uses either an inter-
rupt or a DMA channel, then do_config also performs any setup requirements. For example, for controllers that connect to the EISA bus,
do_config initializes the controller according to the parameters specified in the EISA configuration file.
NOTES
The do_config routine is a generic interface that maps to a bus-specific interface that actually initializes the specified device. Using
this routine to initialize a device makes the driver more portable across different bus architectures. Not all buses support the do_config
routine.
RETURN VALUES
None
