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, ddi_io_rep_putw, ddi_io_rep_putl, ddi_io_rep_putb - 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).

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() func-
       tions 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 char-
       acteristics.

CONTEXT

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

NOTES

       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.  See the  following table for the new name equivalents:
