2011-07-22x86/PCI: config space accessor functions should not ignore the segment argumentJan Beulich
Without this change, the majority of the raw PCI config space access functions silently ignore a non-zero segment argument, which is certainly wrong. Apart from pci_direct_conf1, all other non-MMCFG access methods get used only for non-extended accesses (i.e. assigned to raw_pci_ops only). Consequently, with the way raw_pci_{read,write}() work, it would be a coding error to call these functions with a non-zero segment (with the current call flow this cannot happen afaict). The access method 1 accessor, as it can be used for extended accesses (on AMD systems) instead gets checks added for the passed in segment to be zero. This would be the case when on such a system having multiple PCI segments (don't know whether any exist in practice) MMCFG for some reason is not usable, and method 1 gets selected for doing extended accesses. Rather than accessing the wrong device's config space, the function will now error out. v2: Convert BUG_ON() to WARN_ON(), and extend description as per Ingo's request.

2011-07-22PCI: Assign values to 'pci_obff_signal_type' enumeration constantsMyron Stowe
'pci_obff_signal_type' is passed between drivers and the kernel API. This patch explicitly assigns values to the enumeration type's constants which aids in detecting any future changes or additions that would break the kernel's ABI. No functional change.

2011-07-22x86/PCI: reduce severity of host bridge window conflict warningsBjorn Helgaas
Host bridge windows are top-level resources, so if we find a host bridge window conflict, it's probably with a hard-coded legacy reservation. Moving host bridge windows is theoretically possible, but we don't support it; we just ignore windows with conflicts, and it's not worth making this a user-visible error.

2011-07-22PCI: enumerate the PCI device only removed out PCI hieratchy of OS when ↵Tiejun Chen
re-scanning PCI When hot-plugging a root bridge, we always prevent assigning a bus number that already exists. This makes sure we don't step over an existing bus. But sometimes we only remove PCI device in PCI hieratchy of OS, i,e. echo 1 > /sys/bus/pci/devices/.../remove but actually don't hotplug this device out the platform, so in this case we still should re-scan this bus to enumerate this device when re-scanning PCI again.

2011-07-22PCI: PCIe AER: add aer_recover_queueHuang Ying
In addition to native PCIe AER, now APEI (ACPI Platform Error Interface) GHES (Generic Hardware Error Source) can be used to report PCIe AER errors too. To add support to APEI GHES PCIe AER recovery, aer_recover_queue is added to export the recovery function in native PCIe AER driver. Recoverable PCIe AER errors are reported via NMI in APEI GHES. Then APEI GHES uses irq_work to delay the error processing into an IRQ handler. But PCIe AER recovery can be very time-consuming, so aer_recover_queue, which can be used in IRQ handler, delays the real recovery action into the process context, that is, work queue.

2011-07-22x86/PCI: select direct access mode for mmconfig optionShaohua Li
Direct access is needed in mmconf mode too. There are two reasons: 1. we need it to access first 256 bytes. We have bug before that using mmconf to access pci config space hangs system (when resizing BARs), so we use type1 config for legacy config space. 2. when doing mmconfg bar checking, we need access ACPI _CRS, which might access PCI config space.

While it's declared static, etags points you to the wrong function in drivers/acpi/dock.c and acpiphp_glue.c for example also makes use of some (exported..) functions from this file. If you trust etags and oversee the static declaration (what happened to me) one gets totally confused...

2011-07-08PCI: conditional resource-reallocation through kernel parameter pci=reallocRam Pai
Multiple attempts to dynamically reallocate pci resources have unfortunately lead to regressions. Though we continue to fix the regressions and fine tune the dynamic-reallocation behavior, we have not reached a acceptable state yet. This patch provides a interim solution. It disables dynamic reallocation by default, but adds the ability to enable it through pci=realloc kernel command line parameter.

2011-07-04AT91: Change nand buswidth logic to match hardware default configurationNicolas Ferre
The recently modified nand buswitth configuration is not aligned with board reality: the double footprint on boards is always populated with 8bits buswidth nand flashes. So we have to consider that without particular configuration the 8bits buswidth is selected by default. Moreover, the previous logic was always using !board_have_nand_8bit(), we change it to a simpler: board_have_nand_16bit().
