i2o_msg_in_to_virt(9)
NAME
i2o_msg_in_to_virt - Turn an I2O message to a virtual address
SYNOPSIS
struct i2o_message __iomem *
i2o_msg_in_to_virt(struct i2o_controller * c,
u32 m);
ARGUMENTS
- c
- controller
- m
- message engine value
DESCRIPTION
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.
