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.
