NAME

ddi_io_rep_put8, ddi_io_rep_put16, ddi_io_rep_put32, ddi_io_rep_putb, ddi_io_rep_putl, ddi_io_rep_putw - write multiple data to the mapped device register in I/O space

SYNOPSIS

#include <sys/ddi.h> 
#include <sys/sunddi.h>



void ddi_io_rep_put8(ddi_acc_handle_t handle, uint8_t *host_addr, 
    uin8_t *dev_addr, size_t repcount);

void ddi_io_rep_put16(ddi_acc_handle_t handle, uint16_t *host_addr,
    uin16_t *dev_addr, size_t repcount);

void ddi_io_rep_put32(ddi_acc_handle_t handle, uint32_t *host_addr,
    uin32_t *dev_addr, size_t repcount);

INTERFACE LEVEL

Solaris DDI specific (Solaris DDI). The ddi_io_rep_put8(), ddi_io_rep_put16(), ddi_io_rep_put32(), ddi_io_rep_putb(), ddi_io_rep_putl(), and ddi_io_rep_putw() functions are obsolete. The ddi_rep_put8(9F) function replaces ddi_io_rep_put8(). The ddi_rep_put16(9F) function replaces ddi_io_rep_put16(). The ddi_rep_put32(9F) function replaces ddi_io_rep_put32(). The ddi_rep_put8(9F) function replaces ddi_io_rep_putb(). The ddi_rep_put32(9F) function replaces ddi_io_rep_putl(). The ddi_rep_put16(9F) function replaces ddi_io_rep_putw().

PARAMETERS

handle

: Data access handle returned from setup calls, such as ddi_regs_map_setup(9F).

host_addr

: Base host address.

dev_addr

: Base device address.

repcount

: Number of data accesses to perform.

DESCRIPTION

These routines generate multiple writes to the device address, dev_address, in I/O space. repcount data is copied from the host address, host_addr, to the device address, dev_addr. For each input datum, the ddi_io_rep_put8(), ddi_io_rep_put16(), and ddi_io_rep_put32() functions write 8 bits, 16 bits, and 32 bits of data, respectively, to the device address. host_addr must be aligned to the datum boundary described by the function.

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.
