2019-05-09PCI: Replace printk(KERN_INFO) with pr_info(), etcMohan Kumar1-6/+4
Replace printk() with pr_*() to be more consistent with other logging and avoid checkpatch warnings.

2018-03-19PCI: Tidy commentsBjorn Helgaas1-1/+2
Remove pointless comments that tell us the file name, remove blank line comments, follow multi-line comment conventions. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2018-01-28PCI: Add SPDX GPL-2.0 to replace GPL v2 boilerplateBjorn Helgaas1-2/+1
Add SPDX GPL-2.0 to all PCI files that specified the GPL version 2 license. Remove the boilerplate GPL version 2 language, relying on the assertion in b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license") that the SPDX identifier may be used instead of the full boilerplate text.

Add PCI-specific dev_printk() wrappers and use them to simplify the code slightly. No functional change intended. Signed-off-by: Frederick Lawler <fred@fredlawl.com> [bhelgaas: squash into one patch] Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2013-11-14PCI: Fix whitespace, capitalization, and spelling errorsBjorn Helgaas1-2/+2
Fix whitespace, capitalization, and spelling errors. No functional change. I know "busses" is not an error, but "buses" was more common, so I used it consistently.

2012-11-07PCI: Convert dev_printk(KERN_<LEVEL> to dev_<level>(Joe Perches1-1/+1
dev_<level> calls take less code than dev_printk(KERN_<LEVEL> and reducing object size is good. Coalesce formats for easier grep. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2010-12-23PCI: pci-stub: ignore zero-length id parametersTejun Heo1-0/+3
pci-stub uses strsep() to separate list of ids and generates a warning message when it fails to parse an id. However, not specifying the parameter results in ids set to an empty string. strsep() happily returns the empty string as the first token and thus triggers the warning message spuriously. Make the tokner ignore zero length ids.

2009-09-09PCI: pci-stub: add pci_stub.ids parameterTejun Heo1-1/+44
Add ids module parameter which allows specifying initial IDs for the pci-stub driver. When built into the kernel, pci-stub is linked before any real pci drivers and by setting up IDs from initialization it can prevent built-in drivers from attaching to specific devices. While at it, make pci_stub_probe() print out about devices it grabbed to weed out "but my controller isn't being probed" bug reports.

2009-01-07PCI: pci-stub module to reserve pci deviceChris Wright1-0/+47
When doing device assignment with KVM there's currently nothing to protect the device from having a driver in the host as well as the guest. This trivial module just binds the pci device on the host to a stub driver so that a real host driver can't bind to the device. It has no pci id table, it supports only dynamic ids. # echo "8086 10f5" > /sys/bus/pci/drivers/pci-stub/new_id # echo -n 0000:00:19.0 > /sys/bus/pci/drivers/e1000e/unbind # echo -n 0000:00:19.0 > /sys/bus/pci/drivers/pci-stub/bind # ls -l /sys/bus/pci/devices/0000:00:19.0/driver lrwxrwxrwx 1 root root 0 2008-11-25 19:10 /sys/bus/pci/devices/0000:00:19.0/driver -> ../../../bus/pci/drivers/pci-stub Cc: "Kay, Allen M" <allen.m.kay@intel.com> Cc: "Nakajima, Jun" <jun.nakajima@intel.com> Signed-off-by: Chris Wright <chrisw@sous-sol.org> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
