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()  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 char‐
       acteristics.

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

SEE ALSO
       isa(4),	  ddi_io_get8(9F),    ddi_io_put8(9F),	  ddi_io_rep_get8(9F),
       ddi_regs_map_setup(9F), ddi_device_acc_attr(9S)

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 mem‐
       ory  space only in  PCI local bus.  This is especially true in instruc‐
       tion 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:

       │ddi_io_rep_putl	     ddi_io_rep_put32			      │
