NAME

ddi_io_rep_get8, ddi_io_rep_get16, ddi_io_rep_get32
- 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

illumos DDI specific (illumos 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().

PARAMETERS

handle

host_addr

dev_addr

repcount

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.

CONTEXT

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