.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.
