From 656563e32c3f1dfdc35b3944305ece1c5dfeade5 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Sun, 20 Nov 2005 03:36:45 -0500 Subject: [PATCH] [libata] Print out SATA speed, if link is up Make the SATA phy probe messages a bit more informative. Note this only applies to drivers that use __sata_phy_reset(), which excludes some drivers. --- drivers/scsi/libata-core.c | 20 ++++++++++++++++---- 1 file changed, 16 insertions(+), 4 deletions(-) diff --git a/drivers/scsi/libata-core.c b/drivers/scsi/libata-core.c index 665ae79e1fd6..9f27e8d0e774 100644 --- a/drivers/scsi/libata-core.c +++ b/drivers/scsi/libata-core.c @@ -1444,11 +1444,23 @@ void __sata_phy_reset(struct ata_port *ap) } while (time_before(jiffies, timeout)); /* TODO: phy layer with polling, timeouts, etc. */ - if (sata_dev_present(ap)) + sstatus = scr_read(ap, SCR_STATUS); + if (sata_dev_present(ap)) { + const char *speed; + u32 tmp; + + tmp = (sstatus >> 4) & 0xf; + if (tmp & (1 << 0)) + speed = "1.5"; + else if (tmp & (1 << 1)) + speed = "3.0"; + else + speed = ""; + printk(KERN_INFO "ata%u: SATA link up %s Gbps (SStatus %X)\n", + ap->id, speed, sstatus); ata_port_probe(ap); - else { - sstatus = scr_read(ap, SCR_STATUS); - printk(KERN_INFO "ata%u: no device found (phy stat %08x)\n", + } else { + printk(KERN_INFO "ata%u: SATA link down (SStatus %X)\n", ap->id, sstatus); ata_port_disable(ap); } -- 2.34.1
