# i2o\_msg\_out\_to\_virt(9)

Turn an I2O message to a virtual address

## NAME

i2o\_msg\_out\_to\_virt - Turn an I2O message to a virtual address

## SYNOPSIS

**struct i2o\_message \* i2o\_msg\_out\_to\_virt(struct i2o\_controller \*** *c***, u32** *m***);**

## ARGUMENTS

*c*

controller

*m*

message engine value

## DESCRIPTION

Turn a receive 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 sender side messages as they are ioremap objects provided by the I2O controller.
