      [PATCH] ata_piix: fix ghost device probing by honoring PCS present bits · f1a58eca
      Tejun Heo authored
      Move out PCS handling from piix_sata_prereset() into
      piix_sata_present_mask() and use it from newly implemented
      piix_sata_softreset().  Class codes for devices which are indicated to
      be absent by PCS are cleared to ATA_DEV_NONE.  This fixes ghost device
      problem reported on ICH6 and 7.
      
      This patch moves PCS handling from prereset to softreset, which makes
      two behavior changes.
      
      * perform softreset even when PCS indicates no device
      * PCS handling is repeated before retrying softresets due to reset
        failures.
      
      Both behavior changes are intended and more consistent with how other
      drivers behave.
