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.

SEE ALSO

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 fol‐
       lowing table for the new name equivalents:
