NAME
ddi_io_get8, ddi_io_get16, ddi_io_get32, ddi_io_getb, ddi_io_getl, ddi_io_getw - read data from the mapped device register in I/O space SYNOPSIS
#include <sys/ddi.h> #include <sys/sunddi.h> uint8_t ddi_io_get8(ddi_acc_handle_t handle, uint8_t *dev_addr); uint16_t ddi_io_get16(ddi_acc_handle_t handle, uint16_t *dev_addr); uint32_t ddi_io_get32(ddi_acc_handle_t handle, uint32_t *dev_addr); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). The ddi_io_get8(), ddi_io_get16(), ddi_io_get32(), ddi_io_getb(), ddi_io_getl(), and ddi_io_getw() functions are obsolete. The ddi_get8(9F) function replaces ddi_io_get8(). The ddi_get16(9F) function replaces ddi_io_get16(). The ddi_get32(9F) function replaces ddi_io_get32(). The ddi_get8(9F) function replaces ddi_io_getb(). The ddi_get32(9F) function replaces ddi_io_getl(). The ddi_get16(9F) function replaces ddi_io_getw(). PARAMETERS
handle Data access handle returned from setup calls, such as ddi_regs_map_setup(9F). dev_addr Device address. DESCRIPTION
These routines generate a read of various sizes from the device address, dev_addr, in I/O space. The ddi_io_get8(), ddi_io_get16(), and ddi_io_get32() functions read 8 bits, 16 bits, and 32 bits of data, respectively, from the device address, dev_addr. 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
