NAME
     ddi_mem_get8, ddi_mem_get16,  ddi_mem_get32,  ddi_mem_get64,
     ddi_mem_getb,  ddi_mem_getl,  ddi_mem_getll,  ddi_mem_getw -
     read data from mapped device in the memory  space  or  allo-
     cated DMA memory

SYNOPSIS
     #include 
     #include 



     uint8_t ddi_mem_get8(ddi_acc_handle_t handle, uint8_t *dev_addr);


     uint16_t ddi_mem_get16(ddi_acc_handle_t handle, uint16_t * dev_addr);


     uint32_t ddi_mem_get32(ddi_acc_handle_t handle, uint32_t *dev_addr);


     uint64_t ddi_mem_get64(ddi_acc_handle_t handle, uint64_t *dev_addr);


INTERFACE LEVEL
     Solaris DDI  specific  (Solaris  DDI).  The  ddi_mem_get8(),
     ddi_mem_get16(),      ddi_mem_get32(),      ddi_mem_get64(),
     ddi_mem_getb(),   ddi_mem_getl(),    ddi_mem_getll(),    and
     ddi_mem_getw()  functions  are  obsolete.  The  ddi_get8(9F)
     function replaces ddi_mem_get8(). The ddi_get16(9F) function
     replaces   ddi_mem_get16().   The   ddi_get32(9F)   function
     replaces   ddi_mem_get32().   The   ddi_get64(9F)   function
     replaces ddi_mem_get64(). The ddi_get8(9F) function replaces
     ddi_mem_getb().   The   ddi_get32(9F)   function    replaces
     ddi_mem_getl().    The   ddi_get64(9F)   function   replaces
     ddi_mem_getll().   The   ddi_get16(9F)   function   replaces
     ddi_mem_getw().

PARAMETERS
     handle      The  data  access  handle  returned  from  setup
                 calls, such as ddi_regs_map_setup(9F).


     dev_addr    Base device address.


DESCRIPTION
     These routines generate a read of various sizes from  memory
     space   or   allocated    DMA  memory.  The  ddi_mem_get8(),
     ddi_mem_get16(), ddi_mem_get32(), and ddi_mem_get64()  func-
     tions  read  8  bits,  16 bits, 32 bits and 64 bits of data,
     respectively, from the device address, dev_addr,  in  memory

     space.


     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.

CONTEXT
     These functions can be called from user, kernel,  or  inter-
     rupt context.
