ddi_putl(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 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). The ddi_putb(), ddi_putl(), ddi_putll(), and ddi_putw() functions are obsolete. The ddi_put8() function replaces ddi_putb(). The ddi_put32() function replaces ddi_putl(). The ddi_put64() function replaces ddi_putll(). The ddi_put16() function replaces ddi_putw().

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 characteristics.

For certain bus types, you can call these DDI functions from a high-interrupt context. These types include ISA and SBus buses. See sysbus(4), isa(4), and sbus(4) for details. For the PCI bus, you can, under certain conditions, call these DDI functions from a high-interrupt context. See pci(4).

Context

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