From 62795041418dd63cd9ff6ff7bbdf1d1c513c189b Mon Sep 17 00:00:00 2001 From: Alex Chiang Date: Wed, 4 Feb 2009 11:25:22 -0700 Subject: PCI: enhance physical slot debug information Convert usages of pr_debug to dev_dbg and add physical slot name. Note that we use dev_dbg on the struct pci_bus and still manually print out the PCI slot number (instead of calling dev_dbg on a pci_dev) because a struct pci_bus with empty physical slots will not have any pci_devs. Reviewed-by: Andrew Patterson Signed-off-by: Alex Chiang Signed-off-by: Jesse Barnes --- drivers/pci/slot.c | 18 ++++++++---------- 1 file changed, 8 insertions(+), 10 deletions(-) (limited to 'drivers/pci/slot.c') diff --git a/drivers/pci/slot.c b/drivers/pci/slot.c index 5a8ccb4f604..21189447e54 100644 --- a/drivers/pci/slot.c +++ b/drivers/pci/slot.c @@ -1,8 +1,8 @@ /* * drivers/pci/slot.c * Copyright (C) 2006 Matthew Wilcox - * Copyright (C) 2006-2008 Hewlett-Packard Development Company, L.P. - * Alex Chiang + * Copyright (C) 2006-2009 Hewlett-Packard Development Company, L.P. + * Alex Chiang */ #include @@ -52,8 +52,8 @@ static void pci_slot_release(struct kobject *kobj) struct pci_dev *dev; struct pci_slot *slot = to_pci_slot(kobj); - pr_debug("%s: releasing pci_slot on %x:%d\n", __func__, - slot->bus->number, slot->number); + dev_dbg(&slot->bus->dev, "dev %02x, released physical slot %s\n", + slot->number, pci_slot_name(slot)); list_for_each_entry(dev, &slot->bus->devices, bus_list) if (PCI_SLOT(dev->devfn) == slot->number) @@ -248,9 +248,8 @@ placeholder: if (PCI_SLOT(dev->devfn) == slot_nr) dev->slot = slot; - /* Don't care if debug printk has a -1 for slot_nr */ - pr_debug("%s: created pci_slot on %04x:%02x:%02x\n", - __func__, pci_domain_nr(parent), parent->number, slot_nr); + dev_dbg(&parent->dev, "dev %02x, created physical slot %s\n", + slot_nr, pci_slot_name(slot)); out: kfree(slot_name); @@ -299,9 +298,8 @@ EXPORT_SYMBOL_GPL(pci_renumber_slot); */ void pci_destroy_slot(struct pci_slot *slot) { - pr_debug("%s: dec refcount to %d on %04x:%02x:%02x\n", __func__, - atomic_read(&slot->kobj.kref.refcount) - 1, - pci_domain_nr(slot->bus), slot->bus->number, slot->number); + dev_dbg(&slot->bus->dev, "dev %02x, dec refcount to %d\n", + slot->number, atomic_read(&slot->kobj.kref.refcount) - 1); down_write(&pci_bus_sem); kobject_put(&slot->kobj); -- cgit v1.2.3-70-g09d2
