flags

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.

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