INTERFACE LEVEL

29       Solaris    DDI    specific    (Solaris    DDI).   The   ddi_mem_get8(),
30       ddi_mem_get16(),  ddi_mem_get32(),   ddi_mem_get64(),   ddi_mem_getb(),
31       ddi_mem_getl(), ddi_mem_getll(), and ddi_mem_getw() functions are obso‐
32       lete.  The   ddi_get8(9F)   function   replaces   ddi_mem_get8().   The
33       ddi_get16(9F)  function  replaces  ddi_mem_get16().  The  ddi_get32(9F)
34       function replaces ddi_mem_get32(). The ddi_get64(9F) function  replaces
35       ddi_mem_get64(). The ddi_get8(9F) function replaces ddi_mem_getb(). The
36       ddi_get32(9F) function replaces ddi_mem_getl(). The ddi_get64(9F) func‐
37       tion  replaces  ddi_mem_getll().  The  ddi_get16(9F)  function replaces
38       ddi_mem_getw().

PARAMETERS

41       handle      The data access handle returned from setup calls,  such  as
42                   ddi_regs_map_setup(9F).
43
44
45       dev_addr    Base device address.

DESCRIPTION

49       These  routines  generate  a read of various sizes from memory space or
50       allocated    DMA   memory.   The    ddi_mem_get8(),    ddi_mem_get16(),
51       ddi_mem_get32(), and ddi_mem_get64() functions read 8 bits, 16 bits, 32
52       bits and 64 bits  of  data,  respectively,  from  the  device  address,
53       dev_addr, in memory space.
54
55
56       Each  individual  datum  will automatically be translated to maintain a
57       consistent view between the host and the device based  on  the  encoded
58       information  in  the  data  access  handle. The translation may involve
59       byte-swapping if the host and the device have incompatible endian char‐
60       acteristics.
61

CONTEXT

63       These functions can be called from user, kernel, or interrupt context.
