\fBddi_mem_putb()\fR, \fBddi_mem_putl()\fR, \fBddi_mem_putll()\fR, and

.SH DESCRIPTION
.sp
.LP
These routines generate a write of various sizes to memory space or allocated
\fBDMA \fRmemory. The \fBddi_mem_put8()\fR, \fBddi_mem_put16()\fR,
\fBddi_mem_put32()\fR, and \fBddi_mem_put64()\fR functions write 8 bits, 16
bits, 32 bits and 64 bits of data, respectively, to the device address,
\fIdev_addr\fR, in memory space.
.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.
