2008-07-10x86, VisWS: turn into generic arch, add early init quirksIngo Molnar
add early init quirks for VisWS. This gradually turns the VISWS subarch into a generic PC architecture. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-07-10x86, VisWS: turn into generic arch, make VisWS boot on a regular PCIngo Molnar
first step: make the VISWS subarch boot on a regular PC. We take various shortcuts for that. We copy the generic arch setup file over into the VISWS setup file. This is the only step that is not expected to boot on a real VISWS. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-07-09x86/pci: removing subsys_initcall ordering dependenciesRobert Richter
So far subsys_initcalls has been executed in this order depending on the object order in the Makefile: arch/x86/pci/visws.c:subsys_initcall(pcibios_init); arch/x86/pci/numa.c:subsys_initcall(pci_numa_init); arch/x86/pci/acpi.c:subsys_initcall(pci_acpi_init); arch/x86/pci/legacy.c:subsys_initcall(pci_legacy_init); arch/x86/pci/irq.c:subsys_initcall(pcibios_irq_init); arch/x86/pci/common.c:subsys_initcall(pcibios_init); This patch removes the ordering dependency. There is now only one subsys_initcall function that contains subsystem initialization code with a defined order.

2008-06-10PCI: boot parameter to avoid expansion ROM memory allocationGary Hade
Contention for scarce PCI memory resources has been growing due to an 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 provides a new 'pci=norom' kernel boot parameter that can be used to disable the default PCI expansion ROM memory resource allocation. This provides a way to avoid the above described issues on systems that do not contain PCI devices for which drivers or user-level applications depend on the default PCI expansion ROM memory resource allocation behavior.

2008-06-05PCI/x86: fix up PCI stuff so that PCI_GOANY supports OLPCAndres Salomon
Previously, one would have to specifically choose CONFIG_OLPC and CONFIG_PCI_GOOLPC in order to enable PCI_OLPC. That doesn't really work for distro kernels, so this patch allows one to choose CONFIG_OLPC and CONFIG_PCI_GOANY in order to build in OLPC support in a generic kernel (as requested by Robert Millan). This also moves GOOLPC before GOANY in the menuconfig list. Finally, make pci_access_init return early if we detect OLPC hardware. There's no need to continue probing stuff, and pci_pcbios_init specifically trashes our settings (we didn't run into that before because PCI_GOANY wasn't supported).

2008-05-13x86/PCI: X86_PAT & mprotectVenki Pallipadi
Some versions of X used the mprotect workaround to change caching type from UC to WB, so that it can then use mtrr to program WC for that region [1]. Change the mmap of pci space through /sys or /proc interfaces from UC to UC_MINUS. With this change, X will not need to use mprotect workaround to get WC type since the MTRR mapping type will be honored. The bug in mprotect that clobbers PAT bits is fixed in a follow on patch. So, this X workaround will stop working as well.

this change: | commit 08f1c192c3c32797068bfe97738babb3295bbf42 | Author: Muli Ben-Yehuda <muli@il.ibm.com> | Date: Sun Jul 22 00:23:39 2007 +0300 | | x86-64: introduce struct pci_sysdata to facilitate sharing of ->sysdata | | This patch introduces struct pci_sysdata to x86 and x86-64, and | converts the existing two users (NUMA, Calgary) to use it. | | This lays the groundwork for having other users of sysdata, such as | the PCI domains work. | | The Calgary bits are tested, the NUMA bits just look ok. replaces pcibios_scan_root with pci_scan_bus_parented... but in pcibios_scan_root we have a DMI check: dmi_check_system(pciprobe_dmi_table); when when have several peer root buses this could be called multiple times (which is bad), so move that call to pci_access_init().

2008-05-05x86/pci: add pci=skip_isa_align command lines.Yinghai Lu
so we don't align the io port start address for pci cards. also move out dmi check out acpi.c, because it has nothing to do with acpi. it could spare some calling when we have several peer root buses.
