NAME
       ddi_mem_rep_put8,   ddi_mem_rep_put16,	ddi_mem_rep_put32,   ddi_mem_rep_put64,   ddi_mem_rep_putw,  ddi_mem_rep_putl,	ddi_mem_rep_putll,
       ddi_mem_rep_putb - write multiple data to mapped device in the memory space or allocated DMA memory

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

       void ddi_mem_rep_put8(ddi_acc_handle_t handle, uint8_t *host_addr, uint8_t *dev_addr, size_t repcount, uint_t flags);

       void ddi_mem_rep_put16(ddi_acc_handle_t handle, uint16_t *host_addr, uint16_t *dev_addr, size_t repcount, uint_t flags);

       void ddi_mem_rep_put32(ddi_acc_handle_t handle, uint32_t *host_addr, uint32_t *dev_addr, size_t repcount, uint_t flags);

       void ddi_mem_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).

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 memory space or allocated DMA memory. repcount data is copied from the host address,	host_addr,
       to  the	device address, dev_addr, in memory space. For each input datum, the ddi_mem_rep_put8(), ddi_mem_rep_put16(), ddi_mem_rep_put32(),
       and ddi_mem_rep_put64() functions write 8 bits, 16 bits, 32 bits and 64 bits of data, respectively, to the  device  address.  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 will treat the device address, dev_addr, as a memory buffer location
       on the device and increments 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 from a data register.

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

NOTES
       The  functions described in this manual page previously used symbolic names which specified their data access size; the function names have
       been changed so they now specify a fixed-width data size. See the following table for the new name equivalents:
