NAME
ddi_rep_put8, ddi_rep_put16, ddi_rep_put32, ddi_rep_put64, ddi_rep_putb, ddi_rep_putw, ddi_rep_putl, ddi_rep_putll - 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_rep_put8(ddi_acc_handle_t handle, uint8_t *host_addr, uint8_t *dev_addr, size_t repcount, uint_t flags); void ddi_rep_put16(ddi_acc_handle_t handle, uint16_t *host_addr, uint16_t *dev_addr, size_t repcount, uint_t flags); void ddi_rep_put32(ddi_acc_handle_t handle, uint32_t *host_addr, uint32_t *dev_addr, size_t repcount, uint_t flags); void ddi_rep_put64(ddi_acc_handle_t handle, uint64_t *host_addr, uint64_t *dev_addr, size_t repcount, uint_t flags); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). 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 the mapped memory or device register. repcount data is copied from the host address, host_addr, to the device address, dev_addr. For each input datum, the ddi_rep_put8(), ddi_rep_put16(), ddi_rep_put32(), and ddi_rep_put64() func- tions write 8 bits, 16 bits, 32 bits, and 64 bits of data, respectively, to the device address, dev_addr. 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 char- acteristics. When the flags argument is set to DDI_DEV_AUTOINCR, these functions treat the device address, dev_addr, as a memory buffer location on the device and increment 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 to a data register. CONTEXT
These functions can be called from user, kernel, or interrupt context. SEE ALSO

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.
