40 Solaris DDI specific (Solaris DDI). The \fBddi_mem_get8()\fR,
41 \fBddi_mem_get16()\fR, \fBddi_mem_get32()\fR, \fBddi_mem_get64()\fR,
42 \fBddi_mem_getb()\fR, \fBddi_mem_getl()\fR, \fBddi_mem_getll()\fR, and
43 \fBddi_mem_getw()\fR functions are obsolete. The \fBddi_get8\fR(9F) function
44 replaces \fBddi_mem_get8()\fR. The \fBddi_get16\fR(9F) function replaces
45 \fBddi_mem_get16()\fR. The \fBddi_get32\fR(9F) function replaces
46 \fBddi_mem_get32()\fR. The \fBddi_get64\fR(9F) function replaces
47 \fBddi_mem_get64()\fR. The \fBddi_get8\fR(9F) function replaces
48 \fBddi_mem_getb()\fR. The \fBddi_get32\fR(9F) function replaces
49 \fBddi_mem_getl()\fR. The \fBddi_get64\fR(9F) function replaces
50 \fBddi_mem_getll()\fR. The \fBddi_get16\fR(9F) function replaces
59 The data access handle returned from setup calls, such as
60 \fBddi_regs_map_setup\fR(9F).
75 These routines generate a read of various sizes from memory space or allocated
76 \fBDMA \fRmemory. The \fBddi_mem_get8()\fR, \fBddi_mem_get16()\fR,
77 \fBddi_mem_get32()\fR, and \fBddi_mem_get64()\fR functions read 8 bits, 16
78 bits, 32 bits and 64 bits of data, respectively, from the device address,
79 \fIdev_addr\fR, in memory space.
82 Each individual datum will automatically be translated to maintain a consistent
83 view between the host and the device based on the encoded information in the
84 data access handle. The translation may involve byte-swapping if the host and
85 the device have incompatible endian characteristics.
89 These functions can be called from user, kernel, or interrupt context.
