.SH NAME
ddi_put8, ddi_put16, ddi_put32, ddi_put64, ddi_putb, ddi_putl, ddi_putll,

.SH INTERFACE LEVEL
illumos DDI specific (illumos DDI). The \fBddi_putb()\fR, \fBddi_putl()\fR,
\fBddi_putll()\fR, and \fBddi_putw()\fR functions are obsolete. The
\fBddi_put8()\fR function replaces \fBddi_putb()\fR. The \fBddi_put32()\fR
function replaces \fBddi_putl()\fR. The \fBddi_put64()\fR function replaces
\fBddi_putll()\fR. The \fBddi_put16()\fR function replaces \fBddi_putw()\fR.

.SH DESCRIPTION
These routines generate a write of various sizes to the mapped memory or device
register. The \fBddi_put8()\fR, \fBddi_put16()\fR, \fBddi_put32()\fR, and
\fBddi_put64()\fR functions write 8 bits, 16 bits, 32 bits and 64 bits of data,
respectively, to the device address, \fIdev_addr\fR.
.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.
.sp
.LP
For certain bus types, you can call these \fBDDI\fR functions from a
high-interrupt context. These types include \fBISA\fR and SBus buses.  See
\fBsysbus\fR(4), \fBisa\fR(4), and \fBsbus\fR(4) for details. For the PCI bus,
you can, under certain conditions, call these \fBDDI\fR functions from a
high-interrupt context. See \fBpci\fR(4).
.SH CONTEXT
These functions can be called from user, kernel, or interrupt context.
