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 obsolete. 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) function 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. ATTRIBUTES
