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 regis- ter 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). PARAMETERS
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 char- acteristics. For certain bus types, you can call these DDI functions from a high-interrupt context. These types include ISA and SBus buses. See sys- bus(4), isa(4), and sbus(4) for details. For the PCI bus, you can, under certain conditions, call these DDI functions from a high-inter- rupt context. See pci(4). CONTEXT
These functions can be called from user, kernel, or interrupt context. SEE ALSO

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: Previous Name New Name ddi_putb ddi_put8 ddi_putw ddi_put16 ddi_putl ddi_put32 ddi_putll ddi_put64 SunOS 5.10 18 Nov 2004 ddi_put8(9F)
