ddi_io_rep_get8(9F)					   Kernel Functions for Drivers 				       ddi_io_rep_get8(9F)

NAME
       ddi_io_rep_get8, ddi_io_rep_get16, ddi_io_rep_get32, ddi_io_rep_getb, ddi_io_rep_getl, ddi_io_rep_getw - read multiple data from the mapped
       device register in I/O space

SYNOPSIS
       #include <sys/ddi.h>
       #include <sys/sunddi.h>

       void ddi_io_rep_get8(ddi_acc_handle_t handle, uint8_t *host_addr,
	    uint8_t *dev_addr, size_t repcount);

       void ddi_io_rep_get16(ddi_acc_handle_t handle, uint16_t *host_addr,
	    uint16_t *dev_addr,, size_t repcount);

       void ddi_io_rep_get32(ddi_acc_handle_t handle, uint32_t *host_addr,
	    uint32_t *dev_addr,, size_t repcount);

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI). The ddi_io_rep_get8(), ddi_io_rep_get16(),  ddi_io_rep_get32(),  ddi_io_rep_getb(),	ddi_io_rep_getl(),
       and  ddi_io_rep_getw()  functions  are  obsolete.  The ddi_rep_get8(9F) function replaces ddi_io_rep_get8(). The ddi_rep_get16(9F) function
       replaces  ddi_io_rep_get16().  The  ddi_rep_get32(9F)  function	replaces  ddi_io_rep_get32().  The  ddi_rep_get8(9F)   function   replaces
       ddi_io_rep_getb(). The ddi_rep_get32(9F) function replaces ddi_io_rep_getl(). The ddi_rep_get16(9F) function replaces ddi_io_rep_getw().

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

       host_addr    Base host address.

       dev_addr     Base device address.

       repcount     Number of data accesses to perform.

DESCRIPTION
       These  routines	generate  multiple reads from the device address, dev_addr, in I/O space. repcount data is copied from the device address,
       dev_addr, to the host address, host_addr. For each input datum, the ddi_io_rep_get8(), ddi_io_rep_get16(), and ddi_io_rep_get32() functions
       read 8 bits, 16 bits, and 32 bits of data, respectively, from the device address. host_addr must be aligned to the datum boundary described
       by the function.

       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 char-
       acteristics.

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