DDI_MEM_GET8(9F) DDI_MEM_GET8(9F)
NAME
ddi_mem_get8, ddi_mem_get16, ddi_mem_get32, ddi_mem_get64,
ddi_mem_getb, ddi_mem_getl, ddi_mem_getll, ddi_mem_getw - read data
from mapped device in the memory space or allocated DMA memory
SYNOPSIS
#include <sys/ddi.h>
#include <sys/sunddi.h>
uint8_t ddi_mem_get8(ddi_acc_handle_t handle, uint8_t *dev_addr);
uint16_t ddi_mem_get16(ddi_acc_handle_t handle, uint16_t * dev_addr);
uint32_t ddi_mem_get32(ddi_acc_handle_t handle, uint32_t *dev_addr);
uint64_t ddi_mem_get64(ddi_acc_handle_t handle, uint64_t *dev_addr);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). The ddi_mem_get8(),
ddi_mem_get16(), ddi_mem_get32(), ddi_mem_get64(), ddi_mem_getb(),
ddi_mem_getl(), ddi_mem_getll(), and ddi_mem_getw() functions are obso‐
lete. The ddi_get8(9F) function replaces ddi_mem_get8(). The
ddi_get16(9F) function replaces ddi_mem_get16(). The ddi_get32(9F)
function replaces ddi_mem_get32(). The ddi_get64(9F) function replaces
ddi_mem_get64(). The ddi_get8(9F) function replaces ddi_mem_getb(). The
ddi_get32(9F) function replaces ddi_mem_getl(). The ddi_get64(9F) func‐
tion replaces ddi_mem_getll(). The ddi_get16(9F) function replaces
ddi_mem_getw().
PARAMETERS
handle
The data access handle returned from setup calls, such as
ddi_regs_map_setup(9F).
dev_addr
Base device address.
DESCRIPTION
These routines generate a read of various sizes from memory space or
allocated DMA memory. The ddi_mem_get8(), ddi_mem_get16(),
ddi_mem_get32(), and ddi_mem_get64() functions read 8 bits, 16 bits, 32
bits and 64 bits of data, respectively, from 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.
