handle dev_addr value illumos DDI specific (illumos DDI). The ddi_mem_put8(), ddi_mem_put16(), ddi_mem_put32(), ddi_mem_put64(), ddi_mem_putb(), ddi_mem_putl(), ddi_mem_putll(), and ddi_mem_putw() functions are obsolete. The ddi_put8(9F) function replaces ddi_mem_put8(). The ddi_put16(9F) function replaces ddi_mem_put16(). The ddi_put32(9F) function replaces ddi_mem_put32(). The ddi_put64(9F) function replaces ddi_mem_put64(). These routines generate a write of various sizes to memory space or allocated DMA memory. The ddi_mem_put8(), ddi_mem_put16(), ddi_mem_put32(), and ddi_mem_put64() functions write 8 bits, 16 bits, 32 bits and 64 bits of data, respectively, to the device address, dev_addr, in memory space.

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.

These functions can be called from user, kernel, or interrupt context. See attributes(5) for descriptions of the following attributes:
