taskfile_load_raw — send taskfile registers to host controller
void taskfile_load_raw ( | struct ata_port * | ap, |
struct ata_device * | atadev, | |
const struct taskfile_array * | gtf) ; |
ap
Port to which output is sent
atadev
-- undescribed --
gtf
raw ATA taskfile register set (0x1f1 - 0x1f7)
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.
