 uint8_t *dev_addr, size_t repcount, uint_t flags);

void ddi_mem_rep_put16(ddi_acc_handle_t handle, uint16_t *host_addr,

INTERFACE LEVEL

Solaris DDI specific (Solaris DDI). The ddi_mem_rep_put8(), ddi_mem_rep_put16(), ddi_mem_rep_put32(), ddi_mem_rep_put64(), ddi_mem_rep_putb(), ddi_mem_rep_putl(), ddi_mem_rep_putll(), and ddi_mem_rep_putw() functions are obsolete. The ddi_rep_put8(9F) function replaces ddi_mem_rep_put8(). The ddi_rep_put16(9F) function replaces ddi_mem_rep_put16(). The ddi_rep_put32(9F) function replaces ddi_mem_rep_put32(). The ddi_rep_put64(9F) function replaces ddi_mem_rep_put64(). The ddi_rep_put8(9F) function replaces ddi_mem_rep_putb(). The ddi_rep_put32(9F) function replaces ddi_mem_rep_putl(). The ddi_rep_put64(9F) function replaces ddi_mem_rep_putll(). The ddi_rep_put16(9F) function replaces ddi_mem_rep_putw().

PARAMETERS

handle

The data access handle returned from setup calls, such as ddi_regs_map_setup(9F).

host_addr

Base host address.

dev_addr

Base device address.

repcount

Number of data accesses to perform.

flags

Device address flags:

DDI_DEV_AUTOINCR

Automatically increment the device address, dev_addr, during data accesses.

DDI_DEV_NO_AUTOINCR

Do not advance the device address, dev_addr, during data accesses.

DESCRIPTION

These routines generate multiple writes to memory space or allocated DMA memory. repcount data is copied from the host address, host_addr, to the device address, dev_addr, in memory space. For each input datum, the ddi_mem_rep_put8(), ddi_mem_rep_put16(), ddi_mem_rep_put32(), and ddi_mem_rep_put64() functions write 8 bits, 16 bits, 32 bits and 64 bits of data, respectively, to the device address. dev_addr and host_addr must be aligned to the datum boundary described by the function.

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.

When the flags argument is set to DDI_DEV_AUTOINCR, these functions will treat the device address, dev_addr, as a memory buffer location on the device and increments its address on the next input datum. However, when the flags argument is set to DDI_DEV_NO_AUTOINCR, the same device address will be used for every datum access. For example, this flag may be useful when writing from a data register.

CONTEXT

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