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). The ddi_mem_put8(), ddi_mem_put16(), ddi_mem_put32(), ddi_mem_put64(), ddi_mem_putb(), ddi_mem_putl(), ddi_mem_putll(), and ddi_mem_putw() functions are obsolete. The ddi_put8(9F) function replaces ddi_mem_put8(). The ddi_put16(9F) function replaces ddi_mem_put16(). The ddi_put32(9F) function replaces ddi_mem_put32(). The ddi_put64(9F) function replaces ddi_mem_put64(). The ddi_put8(9F) function replaces ddi_mem_putb(). The ddi_put32(9F) function replaces ddi_mem_putl(). The ddi_put64(9F) function replaces ddi_mem_putll(). The ddi_put16(9F) function replaces ddi_mem_putw().

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 characteristics.
