DDI_MEM_PUT8(9F)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). 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 obso‐
lete. 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) func‐
tion 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 char‐
acteristics.
CONTEXT
These functions can be called from user, kernel, or interrupt context.
