DDI_IO_REP_PUT8(9F) Kernel Functions for Drivers DDI_IO_REP_PUT8(9F)


NAME


ddi_io_rep_put8, ddi_io_rep_put16, ddi_io_rep_put32
- 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


illumos DDI specific (illumos 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().

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.

CONTEXT


These functions can be called from user, kernel, or interrupt context.
