INTERFACE LEVEL

29       Solaris    DDI   specific   (Solaris   DDI).   The   ddi_io_rep_get8(),
30       ddi_io_rep_get16(),       ddi_io_rep_get32(),        ddi_io_rep_getb(),
31       ddi_io_rep_getl(),  and  ddi_io_rep_getw()  functions are obsolete. The
32       ddi_rep_get8(9F)    function    replaces     ddi_io_rep_get8().     The
33       ddi_rep_get16(9F)    function    replaces    ddi_io_rep_get16().    The
34       ddi_rep_get32(9F)    function    replaces    ddi_io_rep_get32().    The
35       ddi_rep_get8(9F)     function     replaces    ddi_io_rep_getb().    The
36       ddi_rep_get32(9F)    function    replaces    ddi_io_rep_getl().     The
37       ddi_rep_get16(9F) function replaces ddi_io_rep_getw().

PARAMETERS

40       handle       The  data access handle returned from setup calls, such as
41                    ddi_regs_map_setup(9F).
42
43
44       host_addr    Base host address.
45
46
47       dev_addr     Base device address.
48
49
50       repcount     Number of data accesses to perform.

DESCRIPTION

54       These  routines  generate  multiple  reads  from  the  device  address,
55       dev_addr,  in  I/O  space.  repcount  data  is  copied  from the device
56       address, dev_addr, to the  host  address,  host_addr.  For  each  input
57       datum,      the      ddi_io_rep_get8(),     ddi_io_rep_get16(),     and
58       ddi_io_rep_get32() functions read 8 bits, 16 bits, and 32 bits of data,
59       respectively, from the device address. host_addr must be aligned to the
60       datum boundary described by the function.
61
62
63       Each individual datum will automatically be translated  to  maintain  a
64       consistent  view  between  the host and the device based on the encoded
65       information in the data access  handle.  The  translation  may  involve
66       byte-swapping if the host and the device have incompatible endian char‐
67       acteristics.

CONTEXT

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