>From 9937ccded1e182b50f1128e80d70768b16d2b5e7 Mon Sep 17 00:00:00 2001 From: Andy Yan <ayan@xxxxxxxxxxx> Date: Thu, 26 Mar 2009 18:32:31 +0800 Subject: [PATCH] PM port setting and attached SATA port selector in discover Default PM port should be set 0 other than 1.For most SATA disk, it is ignored, But I got that some expander reports attached SATA port selector 1 and won't clear it. Host should pass this check and send command with PMport 0. --- drivers/scsi/libsas/sas_ata.c | 2 +- drivers/scsi/libsas/sas_expander.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/scsi/libsas/sas_ata.c b/drivers/scsi/libsas/sas_ata.c index e155011..bea3deb 100644 --- a/drivers/scsi/libsas/sas_ata.c +++ b/drivers/scsi/libsas/sas_ata.c @@ -174,7 +174,7 @@ static unsigned int sas_ata_qc_issue(struct ata_queued_cmd *qc) qc->tf.nsect = 0; } - ata_tf_to_fis(&qc->tf, 1, 0, (u8*)&task->ata_task.fis); + ata_tf_to_fis(&qc->tf, 0, 0, (u8*)&task->ata_task.fis); task->uldd_task = qc; if (ata_is_atapi(qc->tf.protocol)) { memcpy(task->ata_task.atapi_packet, qc->cdb, qc->dev->cdb_len); diff --git a/drivers/scsi/libsas/sas_expander.c b/drivers/scsi/libsas/sas_expander.c index 3da02e4..75ca00b 100644 --- a/drivers/scsi/libsas/sas_expander.c +++ b/drivers/scsi/libsas/sas_expander.c @@ -642,7 +642,7 @@ static struct domain_device *sas_ex_discover_end_dev( struct sas_rphy *rphy; int res; - if (phy->attached_sata_host || phy->attached_sata_ps) + if (phy->attached_sata_host) return NULL; child = kzalloc(sizeof(*child), GFP_KERNEL); -- 1.6.2.1 -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
