INTERFACE LEVEL

     Solaris DDI specific (Solaris DDI).

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  device  address,  dev_addr,
                 during data accesses.

DESCRIPTION

     These routines generate multiple writes to memory  space  or
     allocated  DMA memory. repcount data is copied from the host
     address, host_addr, to  the  device  address,  dev_addr,  in
     memory  space. For each input datum, the ddi_mem_rep_put8(),
     ddi_mem_rep_put16(),        ddi_mem_rep_put32(),         and
     ddi_mem_rep_put64() functions write 8 bits, 16 bits, 32 bits
     and 64 bits of data, respectively, to  the  device  address.
     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  will  treat  the  device  address, dev_addr, as a
     memory buffer location  on the  device  and  increments  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 from a data register.

CONTEXT

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

NOTES

     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:
