I2O_MSG_IN_TO_VIRT(9) Message-based devices I2O_MSG_IN_TO_VIRT(9)NAME
i2o_msg_in_to_virt - Turn an I2O message to a virtual address
struct i2o_message __iomem * i2o_msg_in_to_virt(struct i2o_controller * c, u32 m);
message engine value
Turn a send message from an I2O controller bus address into a Linux virtual address. The shared page frame is a linear block so we simply
have to shift the offset. This function does not work for receive side messages as they are kmalloc objects in a different pool.

do_config - EISA/ISA: Initializes the device to its assigned configuration
struct controller *ctlr_p );
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.
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.
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
Routines: get_config(9r), get_info(9r)
Data Structures: controller(9s)do_config(9r)
