ddi_io_put8(9F) 					   Kernel Functions for Drivers 					   ddi_io_put8(9F)

NAME
ddi_io_put8, ddi_io_put16, ddi_io_put32, ddi_io_putb, ddi_io_putl, ddi_io_putw - write data to the mapped device register in I/O space SYNOPSIS
#include <sys/ddi.h> #include <sys/sunddi.h> void ddi_io_put8(ddi_acc_handle_t handle, uint8_t *dev_addr, uint8_t value); void ddi_io_put16(ddi_acc_handle_t handle, uint16_t *dev_addr, uint16_t value); void ddi_io_put32(ddi_acc_handle_t handle, uint32_t *dev_addr, uint32_t value); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). The ddi_io_put8(), ddi_io_put16(), ddi_io_put32(), ddi_io_putb(), ddi_io_putl(), and ddi_io_putw() functions are obsolete. The ddi_put8(9F) function replaces ddi_io_put8(). The ddi_put16(9F) function replaces ddi_io_put16(). The ddi_put32(9F) function replaces ddi_io_put32(). The ddi_put8(9F) function replaces ddi_io_putb(). The ddi_put32(9F) function replaces ddi_io_putl(). The ddi_put16(9F) function replaces ddi_io_putw(). PARAMETERS
handle Data access handle returned from setup calls, such as ddi_regs_map_setup(9F). dev_addr Base device address. value Data to be written to the device. DESCRIPTION
These routines generate a write of various sizes to the device address, dev_addr, in I/O space. The ddi_io_put8(), ddi_io_put16(), and ddi_io_put32() functions write 8 bits, 16 bits, and 32 bits of data, respectively, to the device address, dev_addr. Each individual datum will automatically be translated to maintain a consistent view between the host and the device based on the encoded information in the data access handle. The translation may involve byte-swapping if the host and the device have incompatible endian char- acteristics. CONTEXT
These functions can be called from user, kernel, or interrupt context. ATTRIBUTES

For drivers using these functions, it may not be easy to maintain a single source to support devices with multiple bus versions. For example, devices may offer I/O space in ISA bus (see isa(4)) but memory space only in PCI local bus. This is especially true in instruction set architectures such as x86 where accesses to the memory and I/O space are different. The functions described in this manual page previously used symbolic names which specified their data access size; the function names have been changed so they now specify a fixed-width data size.
