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

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:
