2012-01-06PNP: work around Dell 1536/1546 BIOS MMCONFIG bug that breaks USBBjorn Helgaas
Some Dell BIOSes have MCFG tables that don't report the entire MMCONFIG area claimed by the chipset. If we move PCI devices into that claimed-but-unreported area, they don't work. This quirk reads the AMD MMCONFIG MSRs and adds PNP0C01 resources as needed to cover the entire area. Example problem scenario: BIOS-e820: 00000000cfec5400 - 00000000d4000000 (reserved) Fam 10h mmconf [d0000000, dfffffff] PCI: MMCONFIG for domain 0000 [bus 00-3f] at [mem 0xd0000000-0xd3ffffff] (base 0xd0000000) pnp 00:0c: [mem 0xd0000000-0xd3ffffff] pci 0000:00:12.0: reg 10: [mem 0xffb00000-0xffb00fff] pci 0000:00:12.0: no compatible bridge window for [mem 0xffb00000-0xffb00fff] pci 0000:00:12.0: BAR 0: assigned [mem 0xd4000000-0xd40000ff] Reported-by: Lisa Salimbas <lisa.salimbas@canonical.com> Reported-by: <thuban@singularity.fr> Tested-by: dann frazier <dann.frazier@canonical.com> References: https://bugzilla.kernel.org/show_bug.cgi?id=31602 References: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/647043 References: https://bugzilla.redhat.com/show_bug.cgi?id=770308 Cc: stable@kernel.org # 2.6.34+ Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

Because populate_msi_sysfs fails, we never registered any of the msi irq sysfs objects, but free_msi_irqs still calls kobject_del and kobject_put on each of them, which gets flagged in the above stack trace.

Convert from pci_scan_bus() to pci_scan_root_bus() and remove root bus fixups. This fixes the problem of "early" and "header" quirks seeing incorrect root bus resources. This arch was unusual because it filled in bus->resource[0..3] in pcibios_init(), then overwrote them, applied io_space.offset and checked for unset resources in pcibios_fixup_bus(). I moved all of that to a new pci_controller_apertures() that we can use before scanning the root bus.

2012-01-06x86/PCI: convert to pci_create_root_bus() and pci_scan_root_bus()Bjorn Helgaas
x86 has two kinds of PCI root bus scanning: (1) ACPI-based, using _CRS resources. This used pci_create_bus(), not pci_scan_bus(), because ACPI hotplug needed to split the pci_bus_add_devices() into a separate host bridge .start() method. This patch parses the _CRS resources earlier, so we can build a list of resources and pass it to pci_create_root_bus(). Note that as before, we parse the _CRS even if we aren't going to use it so we can print it for debugging purposes. (2) All other, which used either default resources (ioport_resource and iomem_resource) or information read from the hardware via amd_bus.c or similar. This used pci_scan_bus(). This patch converts x86_pci_root_bus_res_quirks() (previously called from pcibios_fixup_bus()) to x86_pci_root_bus_resources(), which builds a list of resources before we call pci_scan_root_bus(). We also use x86_pci_root_bus_resources() if we have ACPI but are ignoring _CRS.

2012-01-06x86/PCI: use pci_scan_bus() instead of pci_scan_bus_parented()Bjorn Helgaas

2012-01-06microblaze/PCI: use pci_scan_root_bus()Bjorn Helgaas
Microblaze doesn't need to replace pci_scan_child_bus() or do anything special before pci_bus_add_devices(), so we can use the more generic PCI path in pci_scan_root_bus().

2012-01-06microblaze/PCI: convert to pci_create_root_bus() for correct root bus resourcesBjorn Helgaas
Convert from pci_create_bus() to pci_create_root_bus(). This way the root bus resources are correct immediately. This patch doesn't fix a problem because microblaze fixed the resources before scanning the bus, but it makes microblaze more consistent with other architectures. It also allows us to use the pci_scan_root_bus() path safely.

2012-01-06microblaze/PCI: fix pci_bus_for_each_resource() usageBjorn Helgaas
The pci_bus_for_each_resource() iterator sets "res" itself, so there's no need to look it up in the bus->resource[] table. Logically part of 89a74ecccd and 8a66da71fa.

Convert from pci_create_bus() to pci_create_root_bus(). This way the root bus resources are correct immediately. This fixes the problem of "early" and "header" quirks seeing incorrect root bus resources. We can't use pci_scan_root_bus() because, like x86, ACPI hotplug currently requires pci_bus_add_devices() in a separate host bridge .start() method. v2: fix compile error by using window resource pointer instead CC: Tony Luck <tony.luck@intel.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2012-01-06frv/PCI: convert to pci_scan_root_bus() for correct root bus resourcesBjorn Helgaas
Convert from pci_scan_bus() to pci_scan_root_bus() and remove root bus resource fixups. This fixes the problem of "early" and "header" quirks seeing incorrect root bus resources. Note that peer root buses are scanned with pci_scan_bus() (which is now deprecated), so they have the default ioport_resource and iomem_resource resources. This is unchanged from before, but these resources are incorrect, and I don't know how to discover the correct ones.
