SYNOPSIS
#include <sys/ddi.h>
#include <sys/sunddi.h>
void ddi_rep_put8(ddi_acc_handle_t handle, uint8_t *host_addr,
uint8_t *dev_addr, size_t repcount, uint_t flags);
void ddi_rep_put16(ddi_acc_handle_t handle, uint16_t *host_addr,
uint16_t *dev_addr, size_t repcount, uint_t flags);
void ddi_rep_put32(ddi_acc_handle_t handle, uint32_t *host_addr,
uint32_t *dev_addr, size_t repcount, uint_t flags);
void ddi_rep_put64(ddi_acc_handle_t handle, uint64_t *host_addr,
uint64_t *dev_addr,size_t repcount, uint_t flags);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). The ddi_rep_putb(), ddi_rep_putl(),
ddi_rep_putll(), and ddi_rep_putw() functions are obsolete. The
ddi_rep_put8() function replaces ddi_rep_putb(). The ddi_rep_put32()
function replaces ddi_rep_putl(). The ddi_rep_put64() function replaces
ddi_rep_putll(). The ddi_rep_put16() function replaces ddi_rep_putw().
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.
flags Device address flags:
DDI_DEV_AUTOINCR Automatically increment the device
address, dev_addr, during data
accesses.
DDI_DEV_NO_AUTOINCR Do not advance the device address,
dev_addr, during data accesses.
DESCRIPTION
These routines generate multiple writes to the mapped memory or device
register. repcount data is copied from the host address, host_addr, to
the device address, dev_addr. For each input datum, the ddi_rep_put8(),
ddi_rep_put16(), ddi_rep_put32(), and ddi_rep_put64() functions write 8
bits, 16 bits, 32 bits, and 64 bits of data, respectively, to the
device address, dev_addr. dev_addr and 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.
When the flags argument is set to DDI_DEV_AUTOINCR, these functions
treat the device address, dev_addr, as a memory buffer location on the
device and increment its address on the next input datum. However, when
the flags argument is set to DDI_DEV_NO_AUTOINCR, the same device
address will be used for every datum access. For example, this flag may
be useful when writing to a data register.
CONTEXT
These functions can be called from user, kernel, or interrupt context.
