Kernel Functions for Drivers                      ddi_io_get8(9F)



NAME
     ddi_io_get8,   ddi_io_get16,   ddi_io_get32,    ddi_io_getb,
     ddi_io_getl,  ddi_io_getw - read data from the mapped device
     register in I/O space

SYNOPSIS
     #include 
     #include 



     uint8_t ddi_io_get8(ddi_acc_handle_t handle, uint8_t *dev_addr);


     uint16_t ddi_io_get16(ddi_acc_handle_t handle, uint16_t  *dev_addr);


     uint32_t ddi_io_get32(ddi_acc_handle_t handle, uint32_t  *dev_addr);


INTERFACE LEVEL
     Solaris  DDI  specific  (Solaris  DDI).  The  ddi_io_get8(),
     ddi_io_get16(),        ddi_io_get32(),        ddi_io_getb(),
     ddi_io_getl(), and ddi_io_getw() functions are obsolete. The
     ddi_get8(9F)    function    replaces    ddi_io_get8().   The
     ddi_get16(9F)   function   replaces   ddi_io_get16().    The
     ddi_get32(9F)    function   replaces   ddi_io_get32().   The
     ddi_get8(9F)   function    replaces    ddi_io_getb().    The
     ddi_get32(9F)    function    replaces   ddi_io_getl().   The
     ddi_get16(9F) function replaces ddi_io_getw().

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


     dev_addr    Device address.


DESCRIPTION
     These routines generate a read of  various  sizes  from  the
     device  address,  dev_addr, in I/O space. The ddi_io_get8(),
     ddi_io_get16(), and ddi_io_get32() functions read 8 bits, 16
     bits,  and  32  bits  of data, respectively, from the device
     address, dev_addr.


     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.
