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 characteristics.
