2007-10-12PCI: Add 'nodomains' boot option, and pci_domains_supported globalJeff Garzik
* Introduce pci_domains_supported global, hardcoded to zero if !CONFIG_PCI_DOMAINS. * Introduce 'nodomains' boot option, which clears pci_domains_supported on platforms that enable it by default (x86, x86-64, and others when they are converted to use this).

2007-10-12PCI: modify PCI bridge control ISA flag for clarityGary Hade
Modify PCI Bridge Control ISA flag for clarity This patch changes PCI_BRIDGE_CTL_NO_ISA to PCI_BRIDGE_CTL_ISA and modifies it's clarifying comment and locations where used. The change reduces the chance of future confusion since it makes the set/unset meaning of the bit the same in both the bridge control register and bridge_ctl field of the pci_bus struct.

2007-10-12PCI: use _CRS for PCI resource allocationGary Hade
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.

2007-10-12PCI: avoid P2P prefetch window for expansion ROMsGary Hade
Avoid creating P2P prefetch window for expansion ROMs Because of the future possibility that P2P prefetch windows will contain address ranges above 4GB some BIOSes are providing space in the P2P non-prefetch windows for expansion ROMs. This is due to expansion ROM BAR 32-bit limitation. When expansion ROM BARs without BIOS assigned address(es) are currently found behind a P2P bridge, the kernel attempts to create a P2P prefetch window for them even though space for them has already been provided in the non-prefetch window. _CRS on some systems with certain resource conservation conscious BIOSes may not provide the extra 1MB or more memory resource needed for the expansion ROM motivated prefetch window causing resource allocation errors. This change corrects the problem by removing IORESOURCE_PREFETCH from the expansion ROM flags initialization. It also removes IORESOURCE_CACHEABLE which seems inappropriate if only non-cacheable memory is available.

2007-10-12PCI: skip ISA ioresource alignment on some systemsGary Hade
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.

2007-10-12PCI: remove transparent bridge sizingGary Hade
Remove transparent bridge sizing. Due to code in pci_read_bridge_bases() [drivers/pci/probe.c] the child bus of a transparent bridge already has access to the parent bus resources so transparent bridge sizing appears unnecessary. The bridge sizing includes alignment and granularity adjustments that can cause significantly more memory to be reserved from the parant bus than required by devices on the child bus and allotted by _CRS.

2007-10-12dma_free_coherent() needs irqs enabled (sigh)David Brownell
On at least ARM (and I'm told MIPS too) dma_free_coherent() has a newish call context requirement: unlike its dma_alloc_coherent() sibling, it may not be called with IRQs disabled. (This was new behavior on ARM as of late 2005, caused by ARM SMP updates.) This little surprise can be annoyingly driver-visible. Since it looks like that restriction won't be removed, this patch changes the definition of the API to include that requirement. Also, to help catch nonportable drivers, it updates the x86 and swiotlb versions to include the relevant warnings. (I already observed that it trips on the bus_reset_tasklet of the new firewire_ohci driver.)
