ddi_mem_get8(9F)					   Kernel Functions for Drivers 					  ddi_mem_get8(9F)

NAME
       ddi_mem_get8,  ddi_mem_get16, ddi_mem_get32, ddi_mem_get64, ddi_mem_getb, ddi_mem_getl, ddi_mem_getll, ddi_mem_getw - read data from mapped
       device in the memory space or allocated DMA memory

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

       uint8_t ddi_mem_get8(ddi_acc_handle_t handle, uint8_t *dev_addr);

       uint16_t ddi_mem_get16(ddi_acc_handle_t handle, uint16_t * dev_addr);

       uint32_t ddi_mem_get32(ddi_acc_handle_t handle, uint32_t *dev_addr);

       uint64_t ddi_mem_get64(ddi_acc_handle_t handle, uint64_t *dev_addr);

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI). The ddi_mem_get8(), ddi_mem_get16(), ddi_mem_get32(), ddi_mem_get64(), ddi_mem_getb(),  ddi_mem_getl(),
       ddi_mem_getll(),  and  ddi_mem_getw() functions are obsolete. The ddi_get8(9F) function replaces ddi_mem_get8(). The ddi_get16(9F) function
       replaces ddi_mem_get16(). The ddi_get32(9F) function replaces ddi_mem_get32(). The ddi_get64(9F)  function  replaces  ddi_mem_get64().  The
       ddi_get8(9F)  function  replaces  ddi_mem_getb().  The  ddi_get32(9F) function replaces ddi_mem_getl(). The ddi_get64(9F) function replaces
       ddi_mem_getll(). The ddi_get16(9F) function replaces ddi_mem_getw().

PARAMETERS
       handle	   The data access handle returned from setup calls, such as ddi_regs_map_setup(9F).

       dev_addr    Base device address.

DESCRIPTION
       These routines generate a read of various  sizes  from  memory  space  or  allocated   DMA  memory.  The  ddi_mem_get8(),  ddi_mem_get16(),
       ddi_mem_get32(),  and  ddi_mem_get64()  functions read 8 bits, 16 bits, 32 bits and 64 bits of data, respectively, from the device address,
       dev_addr, in memory space.

       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.

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