* Change pci_raw_ops to pci_raw_read/writeMatthew Wilcox2008-02-109-32/+47
| | | | | | | | | | We want to allow different implementations of pci_raw_ops for standard and extended config space on x86. Rather than clutter generic code with knowledge of this, we make pci_raw_ops private to x86 and use it to implement the new raw interface -- raw_pci_read() and raw_pci_write().

* PCI x86: always use conf1 to access config space below 256 bytesIvan Kokshaysky2008-02-104-67/+19Star
| | | | | | | | | | | | | | | Thanks to Loic Prylli <loic@myri.com>, who originally proposed this idea. Always using legacy configuration mechanism for the legacy config space and extended mechanism (mmconf) for the extended config space is a simple and very logical approach. It's supposed to resolve all known mmconf problems. It still allows per-device quirks (tweaking dev->cfg_size). It also allows to get rid of mmconf fallback code.

| | | | | | | | | | This adds support for flushing the chipsets on the 915, 945, 965 and G33 families of Intel chips. The BIOS doesn't seem to always allocate the BAR on the 965 chipsets so I have to use pci resource code to create a resource It adds an export for pcibios_align_resource.

* PCI: remove default PCI expansion ROM memory allocationGary Hade2008-01-301-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | increasing number of PCI slots in large multi-node systems. The kernel currently attempts by default to allocate memory for all PCI expansion ROMs so there has also been an increasing number of PCI memory allocation failures seen on these systems. This occurs because the BIOS either (1) provides insufficient PCI memory resource for all the expansion ROMs or (2) provides adequate PCI memory resource for expansion ROMs but provides the space in kernel unexpected BIOS assigned P2P non-prefetch windows. The resulting PCI memory allocation failures may be benign when related to memory requests for expansion ROMs themselves but in some cases they can occur when attempting to allocate space for more critical BARs. This can happen when a successful expansion ROM allocation request consumes memory resource that was intended for a non-ROM BAR. We have seen this happen during PCI hotplug of an adapter that contains a P2P bridge where successful memory allocation for an expansion ROM BAR on device behind the bridge consumed memory that was intended for a non-ROM BAR on the P2P bridge. In all cases the allocation failure messages can be very confusing for users. This patch addresses the issue by changing the kernel default behavior so that expansion ROM memory allocations are no longer attempted by default when the BIOS has not assigned a specific address range to the expansion ROM BAR. This was done by changing the 'pci=rom' boot option behavior for BIOS unassigned expansion ROMs to actually match it's current kernel-parameters.txt description which already implies "off" by default. Behavior for BIOS assigned expansion ROMs implemented in pcibios_assign_resources() [arch/x86/pci/i386.c] is unchanged.

* PCI: use _CRS for PCI resource allocationGary Hade2007-10-133-0/+143
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use _CRS for PCI resource allocation This patch resolves an issue where incorrect PCI memory and i/o ranges are being assigned to hotplugged PCI devices on some IBM systems. The resource mis-allocation not only makes the PCI device unuseable but often makes the entire system unuseable due to resulting machine checks. The hotplug capable PCI slots on the affected systems are not located under a standard P2P bridge but are instead located under PCI root bridges or subtractive decode P2P bridges. For example, the IBM x3850 contains 2 hotplug capable PCI-X slots and 4 hotplug capable PCIe slots with the PCI-X slots each located under a PCI root bridge and the PCIe slots each located under a subtractive decode P2P bridge. The current i386/x86_64 PCI resource allocation code does not use _CRS returned resource information. No other resource information source is available for slots that are not below a standard P2P bridge so incorrect ranges are being allocated from e820 hole causing the bad result. This patch causes the kernel to use _CRS returned resource info. It is roughly based on a change provided by Matthew Wilcox for the ia64 kernel in 2005. Due to possible buggy BIOS factor and possible yet to be discovered kernel issues the function is disabled by default and can be enabled with pci=use_crs.

* PCI: skip ISA ioresource alignment on some systemsGary Hade2007-10-133-0/+56
| | | | | | | | | | | | | | Skip ISA ioresource alignment on some systems To conserve limited PCI i/o resource on some IBM multi-node systems, the BIOS allocates (via _CRS) and expects the kernel to use addresses in ranges currently excluded by pcibios_align_resource() [i386/pci/i386.c]. This change allows the kernel to use the currently excluded address ranges on the IBM x3800, x3850, and x3950.
