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()  func-
     tions  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 characteristics.

CONTEXT

     These functions can be called from user, kernel,  or  inter-
     rupt 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:
