ddi_put8(9F)						   Kernel Functions for Drivers 					      ddi_put8(9F)

NAME
       ddi_put8, ddi_put16, ddi_put32, ddi_put64, ddi_putb, ddi_putl, ddi_putll, ddi_putw - write data to the mapped memory address, device regis-
       ter or allocated DMA memory address

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

       void ddi_put8(ddi_acc_handle_t handle, uint8_t *dev_addr, uint8_t value);

       void ddi_put16(ddi_acc_handle_t handle, uint16_t *dev_addr, uint16_t value);

       void ddi_put32(ddi_acc_handle_t handle, uint32_t *dev_addr, uint32_t value);

       void ddi_put64(ddi_acc_handle_t handle, uint64_t *dev_addr, uint64_t value);

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI).

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

       value	       The data to be written to the device.

       dev_addr        Base device address.

DESCRIPTION
       These routines generate a write of various sizes to the mapped memory or device register. The  ddi_put8(),  ddi_put16(),  ddi_put32(),  and
       ddi_put64() functions write 8 bits, 16 bits, 32 bits and 64 bits of data, respectively, to the device address, dev_addr.

       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.

       For  certain bus types, you can call these DDI functions from a	high-interrupt context.  These types include ISA and SBus buses.  See sys-
       bus(4), isa(4), and sbus(4) for details.  For the PCI bus, you can, under certain conditions, call these DDI functions from  a  high-inter-
       rupt context. See pci(4).

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:

       Previous Name			New Name

       ddi_putw 			ddi_put16
       ddi_putl 			ddi_put32
       ddi_putll			ddi_put64
