NAME
       ddi_mem_rep_get8,   ddi_mem_rep_get16,	ddi_mem_rep_get32,   ddi_mem_rep_get64,   ddi_mem_rep_getw,  ddi_mem_rep_getl,	ddi_mem_rep_getll,
       ddi_mem_rep_getb - read multiple data from mapped device in the memory space or allocated DMA memory

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

       void ddi_mem_rep_get8(ddi_acc_handle_t handle, uint8_t *host_addr, uint8_t *dev_addr, size_t repcount, uint_t flags);

       void ddi_mem_rep_get16(ddi_acc_handle_t handle, uint16_t *host_addr, uint16_t *dev_addr, size_t repcount, uint_t flags);

       void ddi_mem_rep_get32(ddi_acc_handle_t handle, uint32_t *host_addr, uint32_t *dev_addr, size_t repcount, uint_t flags);

       void ddi_mem_rep_get64(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 reads from memory space or allocated DMA  memory.  repcount  data  is  copied  from  the  device  address,
       dev_addr,  in  memory  space  to  the  host  address,  host_addr.  For  each  input  datum,  the  ddi_mem_rep_get8(),  ddi_mem_rep_get16(),
       ddi_mem_rep_get32(), and ddi_mem_rep_get64() functions read 8 bits, 16 bits, 32 bits and 64 bits of data,  respectively,  from  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 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 reading 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:
