Solaris DDI specific (Solaris DDI). The \fBddi_io_rep_get8()\fR,
\fBddi_io_rep_get16()\fR, \fBddi_io_rep_get32()\fR, \fBddi_io_rep_getb()\fR,
\fBddi_io_rep_getl()\fR, and \fBddi_io_rep_getw()\fR functions are obsolete.
The \fBddi_rep_get8\fR(9F) function replaces \fBddi_io_rep_get8()\fR. The
\fBddi_rep_get16\fR(9F) function replaces \fBddi_io_rep_get16()\fR. The
\fBddi_rep_get32\fR(9F) function replaces \fBddi_io_rep_get32()\fR. The
\fBddi_rep_get8\fR(9F) function replaces \fBddi_io_rep_getb()\fR. The
\fBddi_rep_get32\fR(9F) function replaces \fBddi_io_rep_getl()\fR. The
\fBddi_rep_get16\fR(9F) function replaces \fBddi_io_rep_getw()\fR.

.SH DESCRIPTION
.sp
.LP
These routines generate multiple reads from the device address, \fIdev_addr\fR,
in I/O space. \fIrepcount\fR data is copied from the device address,
\fIdev_addr\fR, to the host address, \fIhost_addr\fR. For each input datum, the
\fBddi_io_rep_get8()\fR, \fBddi_io_rep_get16()\fR, and \fBddi_io_rep_get32()\fR
functions read 8 bits, 16 bits, and 32 bits of data, respectively, from the
device address. \fIhost_addr\fR must be aligned to the datum boundary described
by the function.
.sp
.LP
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.
.SH CONTEXT
.sp
.LP
These functions can be called from user, kernel, or interrupt context.
