ddi_put8(9F)						   Kernel Functions for Drivers 					      ddi_put8(9F)

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
ddi_get8(9F), ddi_regs_map_free(9F), ddi_regs_map_setup(9F), ddi_rep_get8(9F), ddi_rep_put8(9F), ddi_device_acc_attr(9S) 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: 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)
