* PCI: avoid early PCI mmconfig init if pci=noearly is given in cmdlineJacob Pan2009-01-07
| | | | | | | | | | Early type 1 accesses can cause problems on some platforms, and pci=noearly is supposed to prevent them from occurring.

| | | | | | | | | | | | | | The _OSC capability OSC_EXT_PCI_CONFIG_SUPPORT is set when the root bridge is added with pci_acpi_osc_support() if we can access PCI extended config space. This adds the function pci_ext_cfg_avail which returns true if we can access PCI extended config space (offset greater than 0xff). It currently only returns false if arch=x86 and raw_pci_ext_ops is not set (which might happen if pci=nommcfg is set on the kernel command-line).

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: Changes reboot behavior. If port CF9 seems to be safe to touch, attempt it before trying the keyboard controller. Port CF9 is not available on all chipsets (a significant but decreasing number of modern chipsets don't implement it), but port CF9 itself should in general be safe to poke (no ill effects if unimplemented) on any system which has PCI Configuration Method #1 or #2, as it falls inside the PCI configuration port range in both cases. No chipset without PCI is known to have port CF9, either, although an explicit "pci=bios" would mean we miss this and therefore don't use port CF9. An explicit "reboot=pci" can be used to force the use of port CF9. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

From: Stefan Assmann <sassmann@suse.de> Subject: Introduce config option for pci reroute quirks The config option X86_REROUTE_FOR_BROKEN_BOOT_IRQS is introduced to enable (or disable) the redirection of the interrupt handler to the boot interrupt line by default. Depending on the existence of interrupt masking / threaded interrupt handling in the kernel (vanilla, rt, ...) and the maturity of the rerouting patch, users can enable or disable the redirection by default. This means that the reroute quirk can be applied to any kernel without changing it. Interrupt sharing could be increased if this option is enabled. However this option is vital for threaded interrupt handling, as done by the RT kernel. It should simplify the consolidation with the RT kernel. The option can be overridden by either pci=ioapicreroute or pci=noioapicreroute.

Nevertheless it's possible for Linux to be more resolent about this situation (and similar situations) and work around this bug, by cross-checking the mmconf range against the e820 table and ACPI resources. Change the mconf bus range from [0,0xff] to to [0, 0x3f] to match range [0xf0000000, 0xf4000000) in e820 tables.
