INTERFACE LEVEL
     Solaris DDI specific (Solaris DDI). The  ddi_mem_rep_get8(),
     ddi_mem_rep_get16(),                    ddi_mem_rep_get32(),
     ddi_mem_rep_get64(), ddi_mem_rep_getb(), ddi_mem_rep_getl(),
     ddi_mem_rep_getll(),  and  ddi_mem_rep_getw()  functions are
     obsolete.    The    ddi_rep_get8(9F)    function    replaces
     ddi_mem_rep_get8().  The ddi_rep_get16(9F) function replaces
     ddi_mem_rep_get16(). The ddi_rep_get32(9F) function replaces
     ddi_mem_rep_get32(). The ddi_rep_get64(9F) function replaces
     ddi_mem_rep_get64(). The ddi_rep_get8(9F) function  replaces
     ddi_mem_rep_getb().  The ddi_rep_get32(9F) function replaces
     ddi_mem_rep_getl(). The ddi_rep_get64(9F) function  replaces
     ddi_mem_rep_getll(). The ddi_rep_get16(9F) function replaces
     ddi_mem_rep_getw().

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 reads from memory space  or
     allocated  DMA memory. repcount data is copied from the dev-
     ice address, dev_addr, in memory space to the host  address,
     host_addr.  For  each  input  datum, the ddi_mem_rep_get8(),
     ddi_mem_rep_get16(),        ddi_mem_rep_get32(),         and
     ddi_mem_rep_get64()  functions read 8 bits, 16 bits, 32 bits
     and 64 bits of data, respectively, from 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  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 reading from a data register.
