From f8d4ab3d9bfdb249c3489e92478685b986ef6fcc Mon Sep 17 00:00:00 2001 From: David Milburn Date: Fri, 3 Sep 2010 17:13:03 -0500 Subject: [PATCH] libsas: fix NCQ mixing with non-NCQ commit f0ad30d3d2dc924decc0e10b1ff6dc32525a5d99 upstream. Some cards (like mvsas) have issue troubles if non-NCQ commands are mixed with NCQ ones. Fix this by using the libata default NCQ check routine which waits until all NCQ commands are complete before issuing a non-NCQ one. The impact to cards (like aic94xx) which don't need this logic should be minimal Signed-off-by: James Bottomley Signed-off-by: Greg Kroah-Hartman --- drivers/scsi/libsas/sas_ata.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/scsi/libsas/sas_ata.c b/drivers/scsi/libsas/sas_ata.c index 816ab97eb16d..0ee989fbb0fc 100644 --- a/drivers/scsi/libsas/sas_ata.c +++ b/drivers/scsi/libsas/sas_ata.c @@ -346,6 +346,7 @@ static int sas_ata_scr_read(struct ata_link *link, unsigned int sc_reg_in, static struct ata_port_operations sas_sata_ops = { .phy_reset = sas_ata_phy_reset, .post_internal_cmd = sas_ata_post_internal, + .qc_defer = ata_std_qc_defer, .qc_prep = ata_noop_qc_prep, .qc_issue = sas_ata_qc_issue, .qc_fill_rtf = sas_ata_qc_fill_rtf, -- 2.39.5
