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_getw, ddi_mem_getl, ddi_mem_getll, ddi_mem_getb - 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).

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.

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:
