    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). The ddi_rep_putb(), ddi_rep_putl(), ddi_rep_putll(), and ddi_rep_putw() functions are obsolete. The ddi_rep_put8() function replaces ddi_rep_putb(). The ddi_rep_put32() function replaces ddi_rep_putl(). The ddi_rep_put64() function replaces ddi_rep_putll(). The ddi_rep_put16() function replaces ddi_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 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() functions 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 characteristics.

    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.
