NAME
     ddi_rep_put8, ddi_rep_put16,  ddi_rep_put32,  ddi_rep_put64,
     ddi_rep_putb,  ddi_rep_putw,  ddi_rep_putl,  ddi_rep_putll -
     write data to the mapped memory address, device register  or
     allocated DMA memory address

SYNOPSIS
     #include 
     #include 



     void ddi_rep_put8(ddi_acc_handle_t handle, uint8_t *host_addr,
          uint8_t *dev_addr, size_t repcount, uint_t flags);


     void ddi_rep_put16(ddi_acc_handle_t handle, uint16_t *host_addr,
          uint16_t *dev_addr, size_t repcount, uint_t flags);


     void ddi_rep_put32(ddi_acc_handle_t handle, uint32_t *host_addr,
          uint32_t *dev_addr, size_t repcount, uint_t flags);


     void ddi_rep_put64(ddi_acc_handle_t handle, uint64_t *host_addr,
          uint64_t *dev_addr,size_t repcount, uint_t flags);


INTERFACE LEVEL
     Solaris DDI  specific  (Solaris  DDI).  The  ddi_rep_putb(),
     ddi_rep_putl(),  ddi_rep_putll(),  and  ddi_rep_putw() func-
     tions are obsolete.  The  ddi_rep_put8()  function  replaces
     ddi_rep_putb().   The   ddi_rep_put32()   function  replaces
     ddi_rep_putl().  The   ddi_rep_put64()   function   replaces
     ddi_rep_putll().   The   ddi_rep_put16()  function  replaces
     ddi_rep_putw().

PARAMETERS
     handle       The 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.

     flags        Device address flags:

                  DDI_DEV_AUTOINCR       Automatically  increment
                                         the    device   address,
                                         dev_addr,  during   data
                                         accesses.


                  DDI_DEV_NO_AUTOINCR    Do not advance the  dev-
                                         ice  address,  dev_addr,
                                         during data accesses.



DESCRIPTION
     These routines generate multiple writes to the mapped memory
     or  device  register.  repcount data is copied from the host
     address, host_addr, to the  device  address,  dev_addr.  For
     each   input  datum,  the  ddi_rep_put8(),  ddi_rep_put16(),
     ddi_rep_put32(), and ddi_rep_put64() functions write 8 bits,
     16 bits, 32 bits, and 64 bits of data, respectively,  to the
     device address, dev_addr. dev_addr  and  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.


     When the flags argument is set  to  DDI_DEV_AUTOINCR,  these
     functions  treat  the  device address, dev_addr, as a memory
     buffer location on the device and increment its  address  on
     the  next  input  datum. However, when the flags argument is
     set to DDI_DEV_NO_AUTOINCR, the same device address will  be
     used  for  every datum access. For example, this flag may be
     useful when writing to a data register.

CONTEXT
     These functions can be called from user, kernel,  or  inter-
     rupt context.
