ddi_mem_put8(9F)	 Kernel Functions for Drivers	      ddi_mem_put8(9F)

NAME
       ddi_mem_put8,	  ddi_mem_put16,     ddi_mem_put32,	ddi_mem_put64,
       ddi_mem_putb, ddi_mem_putw, ddi_mem_putl, ddi_mem_putll - write data to
       mapped device in the memory space or allocated DMA memory

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

       void  ddi_mem_put8(ddi_acc_handle_t  handle, uint8_t *dev_addr, uint8_t
       value);

       void   ddi_mem_put16(ddi_acc_handle_t   handle,	 uint16_t   *dev_addr,
       uint16_t value);

       void   ddi_mem_put32(ddi_acc_handle_t   handle,	 uint32_t   *dev_addr,
       uint32_t value);

       void   ddi_mem_put64(ddi_acc_handle_t   handle,	 uint64_t   *dev_addr,
       uint64_t value);

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

       dev_addr	       Base device address.

       value	       The data to be written to the device.

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI).

DESCRIPTION
       These routines generate a write of various sizes	 to  memory  space  or
       allocated     DMA    memory.   The   ddi_mem_put8(),   ddi_mem_put16(),
       ddi_mem_put32(), and ddi_mem_put64() functions write 8 bits,  16	 bits,
       32  bits	 and  64  bits	of  data, respectively, to 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
       ddi_mem_get8(9F),     ddi_mem_rep_get8(9F),     ddi_regs_map_setup(9F),
       ddi_device_acc_attr(9S)

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:
