NAME
       taskfile_load_raw - send taskfile registers to host controller


SYNOPSIS
       void taskfile_load_raw  (struct ata_port * ap,
                                 struct ata_device * atadev,
                                 const struct taskfile_array * gtf);


ARGUMENTS
       ap     Port to which output is sent

       atadev -- undescribed --

       gtf    raw ATA taskfile register set (0x1f1 - 0x1f7)


DESCRIPTION
       Outputs  ATA taskfile to standard ATA host controller using MMIO or PIO
       as indicated by the ATA_FLAG_MMIO flag. Writes  the  control,  feature,
       nsect,  lbal,  lbam,  and  lbah registers. Optionally (ATA_TFLAG_LBA48)
       writes hob_feature, hob_nsect, hob_lbal, hob_lbam, and hob_lbah.

       This function waits for idle (!BUSY and !DRQ) after writing  registers.
       If  the  control register has a new value, this function also waits for
       idle after writing control and before writing the remaining  registers.


LOCKING
       TBD: Inherited from caller.
