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 characteristics.
