PCI: change PCI_MSI help text to recommend enabling

2010-05-11T19:01:10+00:00

Most current machines have no problem with this, and in fact many devices and
features work best (or only!) with MSI.

PCI: push deprecated pci_find_device() function to last user

2010-02-23T00:17:01+00:00

The ISDN4Linux HiSax driver family contains the last remaining users
of the deprecated pci_find_device() function. This patch creates a
private copy of that function in HiSax, and removes the now unused
global function together with its controlling configuration option,
CONFIG_PCI_LEGACY.

PCI: remove pci_find_slot from PCI_LEGACY config description

2009-11-04T21:06:42+00:00

Commit 3b073eda has removed pci_find_slot, so there's no point in
mentioning it in the config description as one of the deprecated APIs
there are enabled by PCI_LEGACY and still used by some drivers.

PCI hotplug: move IOAPIC support from acpiphp to ioapic driver

2009-11-04T21:06:39+00:00

This patch moves PCI I/O APIC support from acpiphp to a separate driver.

Like pciehp and shpchp, acpiphp handles PCI hotplug, i.e., addition and
removal of PCI adapters.  But in addition, acpiphp handles some ACPI
hotplug, such as the addition of new host bridges, and the I/O APIC
support was tangled up with that.

I don't think the I/O APIC support needs to be in acpiphp; PCI I/O APICs
usually appear as a function on a PCI host bridge, and we'll enumerate the
APIC before any of the devices behind the bridge that use it.

As far as I know, nobody actually uses I/O APIC hotplug.  It depends on
acpi_register_ioapic(), which is only implemented for ia64, and I don't
think any vendors have supported I/O chassis hotplug yet.

PCI: initialize and release SR-IOV capability

2009-03-20T17:48:22+00:00

If a device has the SR-IOV capability, initialize it (set the ARI
Capable Hierarchy in the lowest numbered PF if necessary; calculate
the System Page Size for the VF MMIO, probe the VF Offset, Stride
and BARs). A lock for the VF bus allocation is also initialized if
a PF is the lowest numbered PF.

PCI: pci-stub module to reserve pci device

2009-01-07T19:12:38+00:00

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.
