NAME

ddi_put8, ddi_put16, ddi_put32, ddi_put64, ddi_putb, ddi_putl, ddi_putll, ddi_putw − write data to the mapped memory address, device register or allocated DMA memory address

SYNOPSIS

#include <sys/ddi.h>
#include <sys/sunddi.h>

void ddi_put8(ddi_acc_handle_t handle, uint8_t ∗dev_addr, uint8_t value);

void ddi_put16(ddi_acc_handle_t handle, uint16_t ∗dev_addr, uint16_t value);

void ddi_put32(ddi_acc_handle_t handle, uint32_t ∗dev_addr, uint32_t value);

void ddi_put64(ddi_acc_handle_t handle, uint64_t ∗dev_addr, uint64_t value);

INTERFACE LEVEL

Solaris DDI specific (Solaris DDI). 

ARGUMENTS

handle The data access handle returned from setup calls, such as ddi_regs_map_setup(9F). 

value The data to be written to the device. 

dev_addr Base device address. 

DESCRIPTION

These routines generate a write of various sizes to the mapped memory or device register. The ddi_put8(), ddi_put16(), ddi_put32(), and ddi_put64() functions write 8 bits, 16 bits, 32 bits and 64 bits of data, respectively, to 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 characteristics. 

CONTEXT

These functions can be called from user, kernel, or interrupt context. 

SEE ALSO

NOTES

The functions described in this manual page previously used symbolic names which specified their data access size; the function names have been changed so they now specify a fixed-width data size.  See the following table for the new name equivalents:
