From c96f1732e25362d10ee7bcac1df8412a2e6b7d23 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Tue, 24 Mar 2009 10:23:46 +0000 Subject: [libata] Improve timeout handling On a timeout call a device specific handler early in the recovery so that we can complete and process successful commands which timed out due to IRQ loss or the like rather more elegantly. [Revised to exclude the timeout handling on a few devices that inherit from SFF but are not SFF enough to use the default timeout handler] Signed-off-by: Alan Cox Signed-off-by: Jeff Garzik --- drivers/ata/sata_vsc.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'drivers/ata/sata_vsc.c') diff --git a/drivers/ata/sata_vsc.c b/drivers/ata/sata_vsc.c index ef211f333d7..ed70bd28fa2 100644 --- a/drivers/ata/sata_vsc.c +++ b/drivers/ata/sata_vsc.c @@ -308,6 +308,9 @@ static struct scsi_host_template vsc_sata_sht = { static struct ata_port_operations vsc_sata_ops = { .inherits = &ata_bmdma_port_ops, + /* The IRQ handling is not quite standard SFF behaviour so we + cannot use the default lost interrupt handler */ + .lost_interrupt = ATA_OP_NULL, .sff_tf_load = vsc_sata_tf_load, .sff_tf_read = vsc_sata_tf_read, .freeze = vsc_freeze, -- cgit v1.2.3
