handle The data access handle returned from setup calls, such as ddi_regs_map_setup(9F).
dev_addr Base device address.
value The data to be written to the device.
Solaris DDI specific (Solaris DDI).
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.
ddi_mem_get8(9F), ddi_mem_rep_get8(9F), ddi_regs_map_setup(9F), ddi_device_acc_attr(9S)
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:
